Saturday

With their dad having gone out for the day, Billy was in charge of Britney and Sarah. For a boy of fifteen, Billy was mature and diligent, cooking up some breakfast and laying the table, playing the role of a second-parent to his litte sisters. Wearing casual jeans and a black T-shirt, he stepped out the kitchen into the hallway and called up the stairs.
"Breakfast is ready," he said, loudly, "Hurry up girls!"
"Coming," came Sarah's voice.
"In a minute," added, Britney.
Billy went back into the kitchen and sat at the table, munching some toast and gazing idly out the window into the big leafy garden. It was Spring and the day was pleasantly warm.
There was a stampede of feet down the stairs and some girlish giggling, and then Sarah and Britney bustled into the kitchen.
"Hey bro," Britney said, sitting down at the table with Sarah.
"Hiya Britney," Billy said. They all sat and ate, the girls chattering about their day at school yesterday, Billy content to listen and sip his coffee.
"What are you planning to do today?" he asked the girls.
"Probably just hang around the house," Sarah shrugged, munching waffles.
"Just chill out and watch TV," added Britney, "What about you Billy? Gonna sit and play your silly computer games?"
"Counter-Strike is not silly," Billy insisted, solemnly, "I might go out in a minute, go and see my mates. You'll be okay on your own won't you?"
"Yeah," replied both girls simultaneously.
They finished their breakfast and Billy put on his sneakers then headed out the house, saying he'd be back at about two.
"Hooray, the whole house to ourselves," Sarah grinned.
"Excellent," Britney said, "Let's go upstairs."
They scampered up to their bedroom, Sarah going straight to the silver Hi-Fi system on the shelf above her bed and putting on some music - Bjork, her favorite - and turning to her clothes on the bed. She pulled off her nightgown and got a brief thrill when Britney, standing at her open wardrobe across the room, glanced over at her, her eyes lingering for a moment despite having seen her sister nude plenty of times.
"Ah, what to wear?" Britney said, turning to her wardrobe after noticing that her gaze had been met by her sister's. She slipped off her dressing gown so that both twelve-year-old girls stood nude. Britney had her back to Sarah, the latter looking at her twin's sweet round butt. Britney looked round and saw her sister's green eyes fixed to her ass.
"Stop looking at my butt," she smirked.
"Sorry," Sarah said, giggling to hide her embarrassment, "It's a nice butt," she added, still laughing to hide the seriousness of her statement.
"Are you boobs bigger than mine?" Britney asked.
Sarah looked down at her chest. Neither her nor her sister needed bras yet, their 'boobs' little more than tiny bumps on their chests, topped with light pink nipples.
"Dunno," Sarah said.
Britney walked over and stood in front of her sister, both looking over at each other's titties and then down to their own.
"Same size I reckon," Britney concluded, "Mom had big boobies, I reckon we'll both have big 'uns soon, in a few years."
"Yeah, that'll be cool," Sarah giggled, "No hair down there yet?" she asked. Britney stood back and they looked at each other's pussies.
"No," Britney said, "Neither have you. We're still bald! Give it a year or so and we might get some. I'm not in any rush though, I reckon it'd itch having pubic hair."
"Well, you'll have to get used to it! Those hormones will kick in and we'll both have furry beavers."
They both sniggered.
"I'll shave when I grow hair down there," Britney sniffed.
"Me too."
They stood there for a moment, then Britney, for no reason, stepped forward and gave Sarah a quick kiss on the lips, just a little peck. Then she turned and went back over to her wardrobe.
"What to wear," she ponded to herself again.
Sarah shook herself out of her mild shock and reached down and picked up a T-shirt, a tight one with pink and white stripes. She put it on, then slid on some white panties and a pair of jeans and white socks. She looked over ocassionally at Britney who was humming to the music playing on the stereo as she picked out some clothes. She threw on a red jumper, then panties and a pair of light blue shorts that hugged her cute ass nicely. Then she put on knee-length white socks. Both girls put their hair in pony-tails - like Sarah, Britney's hair reached past her waist - and then they went downstairs.
In the large living room, the twins sat on the sofa, close to each other, Sarah flicking through the TV channels and her sister uttering her verdict of "boring" for most of them. Finally they reached an episode of The Simpsons and sat and watched it. After it was over, Sarah stood up and yawned.
"What now?" she asked her sister.
"Dunno," Britney said, "It's the school holidays starting next week, I don't know how we'll cope for six-weeks without school if we can't find something to do for one day."
"Maybe we could go out," Sarah suggested.
"Or," began Britney, before she hesitated. "Or," she continued, "we could go upstairs and do something."
"What?"
"Follow me," Britney insisted, and she got up and walked out the room, her loyal twin in tow.

The girls went upstairs and into their bedroom, where Britney swished the pink drapes shut.
"What are you up to?" asked Sarah, curiously.
"I just thought we should get nekked together," Britney smiled.
"Get nekked?" giggled her sister, "Why?"
"I dunno."
"There's to to be a reason."
"Well...it was just fun this morning, standing naked here together. If you don't want to then..."
"No, it's cool," Sarah quickly said, feeling a buzz of excitement. She lead the way by stripping off her T-shirt, Britney following by taking off her jumper. Shorts and jeans were removed, then socks, and finally off came the panties. Sarah and Britney stood there, the pre-teen girls once again naked.
"What now?" asked Sarah.
"Dunno," shrugged Britney, "I just...like looking at you."
"Oh. Thanks. You're nice to look at naked too."
"I was thinking, we should frig ourselves together."
"What?" frowned Sarah.
"Well, I know you do it," smirked Britney, "I'm a light-sleeper. I can hear you moaning in bed quietly when you finger yourself. I pretend to be asleep. You don't hear me frig myself do you Sarah?"
"No. Never. I must be a heavy sleeper. I didn't know you knew I did it." She blushed.
"Hey, don't be embarrassed," laughed Britney, "It's natural, I guess. All girls do it. And boys. Billy probably bashes his bishop every night."
"Yeah," Sarah giggled, "He's okay though, he's got a room to himself. No-one to listen in on him."
"Well, we should do it together," Britney suggested, both girls comfortable as they stood there naked, "Frig ourselves I mean. No point in us waiting until we think the other is asleep. Let's make it a joint activity!"
"Okay," smiled Sarah.
"Plus," added Britney, shyly, "I'd like to, you know...watch you do it. It'd be sexy to watch another girl play with herself."
"Yeah. I can understand that. I'd like to watch you too Britney."
"Let's do it."
Britney sat down at the head of her bed, spreading her legs, her bald pussy lips glistening slightly with moistness from the lewd but sincere conversation she'd just had. Sarah knelt on the bed also, opposite her sister, parting her thighs, the girls looking at each other's cunts.
"How do you do it?" asked Britney.
"Hmm? Oh, you mean frig?" said Sarah, "Just...I dunno. How many ways are there?"
"I stick one finger in like this," Britney explained, reaching down and sliding her left forefinger to the knuckle in her tight pubescent vagina, "and rub my clit with the other hand." She used the tips of her right forefinger and index-finger to gentle rub her little clitoris. "It feels good that way, doing both actions, fingering and rubbing."
"I usually just put two fingers in like this," Sarah explained, feeling completely comfortable with this explicit sharing of private intimacies. She put two fingers from her right hand to her pussy and slid them in, letting out a slight sigh as she did so. "I don't normally rub my clit though."
"You should do, it feels nice."
"Okay."
"I'll try two fingers too."
Both twelve-year-old twins were now masturbating identically, two fingers in their twats whilst they rubbed their clits. They did so in silence for a few minutes, temporarily lost in their own pleasure, then they made eye-contact and giggled.
"It would be cool to have a vibrator," said Sarah, frigging away.
"Yeah!" Britney agreed, "That'd be great! A nice big one!"
"This is nice though. I like masturbating! It's great!" Sarah felt wonderfully liberated to be able to say such a thing.
"It sure is."
"Mmm...it's nice rubbing my clit! Mmmm."
They continued frigging themselves.
"How long does it take you to cum?" asked Sarah.
"It varies," Britney replied, "Ten-minutes? Maybe sooner, maybe later. It depends how turned on I am."
"I'm feeling really turned on now!" Sarah grinned.
"Me too. This is cool."
"We should do this more often. At night, when dad and Billy are in bed."
"Yeah, it's more fun having someone to do it with. You look really sexy Sarah."
"Thanks. So do you," Sarah smiled, blushing a little.
"It's turning me on watching you frig yourself," Britney added after a moments hesitation, "I mean...you look damn sexy!"
"You too sis."
They smiled, a little nervously, looking down at each other's cunts whilst fingering and rubbing their own. Their small fingers were slick with pre-teen pussy juice as they continued frigging themselves.
"I think I'm gonna cum," grinned Sarah, triumphantly, "Yeah...in a moment...I can feel it rising."
"Keep masturbating," Britney ordered her, "I want to see you climax! I've heard you cum when you've masturbated in the dark when I've pretended to be asleep but I really want to watch you do it."
Sarah was barely listening, her orgasm rising up from her busy fingers. She slid three fingers into her tight cunt whilst her the fingers from her left hand worked speedily over her clit. Her legs were widely parted and her big green eyes were blazing with pleasure. Her eyelids fluttered, she began to pant deeper, and then she came.
"Uuuuh, yeah," she moaned, "Aaah, ah. I'm cumming. Uh."
Britney was busily masturbating and watching intently. "You look so beautiful cumming," she told her sister.
"It feels beautiful," Sarah grinned, her climax dying away, "Wow, that was a good one." She took her fingers from her pussy but still rubbed her clit. "You cum now sis!"
"Okay. It's not far off."
Britney worked on her pussy with her slick fingers, three digits in her cunt now.
"You're nipples are all stiff," smiled Sarah.
"Yeah, that usually happens. So are yours."
Sarah looked down at her own titties, the dark nipples atop those tiny buds sticking out erectly. "Yours are stiffer," she giggled, and reached out and lightly ran her fingers over Britney's left tit, brushing the stiff little red nipple. This gentle touch sent Britney over the edge and she began climaxing as she finger-fucked her twat and rubbed her clitoris.
"I'm cumming now," she said, "Oh yeah, here it is...mmmm. Ah."
"You look so gorgeous," Sarah said, kneeling a bit closer to Britney as her twin hit the apogee of her pleasure.
"Kiss me," Britney said, eyes bright with lust "Kiss me while I cum."
Without hesitation Sarah did so, leaning forwards and planting her lips on Britney's. The kiss immediately turned passionate, their hot little tongues sliding into each other's mouths. They both gave out lewd and muffled moans of pleasure, Britney still fingering her cunt. Sarah reached up with one hand, remembering the pleasure touching Britney's tit had caused the girl, and she stroked Britney's right breast, lightly pinching the nipple. This prolonged her twin's orgasm, Britney shoving her tongue into Sarah's throat as they frenched lustily.
When Britney's climax ebbed away, Sarah pulled back, and they smiled at each other, all previous shyness dissipating.
"That was nice," Britney said, "Thanks."
"My pleasure," her sister said, softly, "It really was, my pleasure."
Britney leaned forwards and placed her hands on Sarah's slender shoulders and kissed her again. Their tongues intwined once more, their wet lips pressed to each other. Sarah wrapped her arms round her twin, their bodies joining and their budding tits pressed together. Britney took her hands from her sister's shoulders and held Sarah gently by the waist then ran her hands up and down Sarah's sides, making the ticklish girl shiver as her sister's fingers gently ran up either side of her ribs. They parted their lips a little, more to get their breath back than anything. With the tips of their noses nudging together, the sisters looked into each other's eyes, smiling childishly with their bright eyes filled with a mixture of love and mischief. Britney's hands were now back resting on Sarah's shoulders, whilst Sarah raised one of her hands and ran her fingers through Britney's silver-blonde hair.
"I love you," she said.
"I love you too Sarah."
The naked twelve-year-old's embraced once more, their pale flesh together, kissing and moaning with lust into each other's mouths. Their desires for each other, sexually, had previously been latent and private within each girl, but now they gave way to it and kissed like heated lovers.
Eventually, they parted, stroking each other's hair and gazing into each other's eyes.
"Shall we finger each other?" suggested Britney.
"Okay," replied Sarah, "I'll do you first."
She moved back and allowed Britney to lay on her back along the bed, her legs straight and parted. Sarah got between her sister's thin bare legs, looking down at her neat little bald cunt. She reached out, a bit nervous, placing a forefinger to her sister's pussy lips, feeling them to be moist. She licked her lips then slid the finger in to the second joint.
"Oh wow, that's nice," Britney said, feeling a shiver of pleasure run down her spine.
"Yeah?"
"Sure! It's great to feel someone else touch me there. Really strange, but nice."
Sarah slid her finger in to the knuckle and held it there, wriggling it slightly and feeling the insides of her sister's cunt.
"It's warm," she commented, "Warm and slippery."
"That's natural lubricant," Britney said, knowledgably, "Remember from sex-ed? It's to help a boy's thing go into you easier."
Sarah pulled her forefinger out of Britney, then slid it back in, repeating this a few times. The she placed her index-finger in there and lightly fingered Britney, making the girl coo with pleasure. Getting more ambitious, Sarah pushed both fingers into Britney's twat, running them back and forth, then reaching out with her other hand to rub Britney's clit with her thumb. This was having a marvelous effect on Britney, the girl closing her eyes and purring with joy. Sarah frigged her twin a little faster, working harder.
"That's good," Britney panted shortly, "Keep fingering me sis. Mmmm. Uuuuh. Shit, I might cum soon...oh yeah. Uuh."
She humped her ass off the bed a little, urging her sister to finger her deeper. Sarah now slid three fingers up Britney's twat, rubbing her clit all the while with her thumb.
"Uuuuuh," grunted Britney, her body tensing, her toes curling, "I'm cumming....Sarah, oh Sarah...you're making me cum. Aaaah."
She almost fainted with pleasure, her orgasm terrific compared to those she'd given herself late at night under the duvet.
When her orgasm subsided, Britney sat up, Sarah withdrawing her hands from between her sister's thighs. The girls kissed then Britney moved away and got off the bed.
"Your turn," she grinned.
"This is going to be fun," Sarah said, laying on her back and parting her legs. Britney got back on the bed, kneeling between Sarah's thighs. The process was repeated with the roles reversed, Britney starting off by inserting one finger gently into Sarah's pussy before sliding in two, then three digits. She rubbed Sarah's clit, working faster until Sarah, after five-minutes, had a delightful climax.
The girls sat up and kissed some more, repeating their genuine and passionate declarations of love for one another.

The girls felt a little sweaty after their 'fun' so decided to have a bath together. The tub was large and oval shaped, easily big enough for two people. The sisters stood and kissed, a finger in each other's cunt, whilst they waited for the bath to fill. When it was, they hopped in, sitting back in the hot soapy water.
"This is fun, bathing with someone else," Sarah commented.
"We haven't done this since we were little," Britney said, "I remember, vaguely, when we were about seven and Billy had to bathe with us. We were on holiday or something, we had a hotel bathroom with a huge tub big enough for us three kids. That was the first time I saw a boy's willie!"
"Yeah, I remember that. Billy was all embarrassed cos we were so curious to see his bits. He showed them to us though. I remember him standing there - he must have been about ten - and us two sitting there and looking at him."
"Then we stood up in the bath and he had a look at our bits. I still remember his comments. 'You girls have boring bits, it's just a slit'." The two girls giggled in the bath.
"We must remind him of that later," Sarah said, "Just to embarrass him."
"In front of his mates or something."
Sarah and Britney spent half-an-hour in the bath. Despite the previous activities of the twins, it was fairly innocent. They kissed a couple of times but mostly just sat back and relaxed, at opposite ends of the bath, knee-to-knee. They washed each other, Sarah shampooing Britney's lovely long hair and soaping down her body, Britney returning the favor to her twin. Then they got out, dried off and padded nude down the hallway. They were about to get dressed when they thought it would be fun to hang around naked. So, they went downstairs, had some lunch, watched a bit of MTV and just slouched around, in the nude and loving the sense of freedom it gave them. Occasionally they kissed, and watching TV together on the sofa they held hands, something they'd always done as toddlers.
At one o'clock they went upstairs and frigged each other some more, taking turns to lie back and be fingered. Their efforts were still amateurish but it didn't matter, they had a wonderful time. After they'd both climaxed once each they lay sleepily in each other's arms.
Sarah was asleep and Britney almost nodding off when the sound of Billy coming through the front door could be heard.
Britney sat up, abruptly.
"Shit," she whispered, "Sarah. Wake up."
She shook her sister, Sarah sleepily sitting up.
"What?" she muttered.
"Billy is home."
"Oh."
"And we're, like, laying on my bed nude and in each other's arms."
"We better er...dress," grinned Sarah.
They leapt up and hurridly threw on the clothes they'd carefully selected that morning. Billy could be heard coming up the stairs, unaware that in the girl's room the twins were busy dressing at record speed.
"Shit shit shit," whispered Sarah, doing up the awkward button-fly on her jeans. Finally she did it. Britney finished adjusting her shorts and straightening her jumper. They were both fully dressed when there was a knock on their door.
"Yeah?" said Britney.
"It's me," Billy said, opening the door, "Hiya girls, what you been up to?"
"Nothing," the twins said together.
"Ah, you've been up to no good," Billy concluded.
"What makes you say that?" demanded Britney, smirking.
"Guilty looks," Billy said, "Anyway, who wants some lunch?"
"We've had some."
"Okay. Later kids," Billy said. He closed the door and went downstairs, feeling a sense of pride at his curious role as a second-father to Sarah and Britney. His father worked hard and with his mother so long in the grave Billy had been caring for his sisters for so long that it was second-nature to adopt a paternal-role. Despite this he was still a laid-back adolescent boy at heart and liked to just act as a brother to his sisters as much as possible.
He was naturally curious as to what they'd been up to when he was out, given that the girl's expressions betrayed the fact that some sort of mischief had been perpertrated. However, Billy didn't think he'd ever figure it out, and anyway he could never have bought himself to tell the girls off if they had done something naughty, he was too much of a gentle youth. Last year Sarah and Britney had used his computer without permission and accidentally deleted some files, and when Billy moaned at them the girls apologized then jokingly offered to let Billy spank them. Britney even bent over, in her tight white jeans, and wiggled her bum. Billy had laughed, the tension broken, and sent the girls on their way. That night, jerking off, he'd found himself thinking of spanking the girls, smacking their bare bottoms, watching the round cheeks jiggle as they were hit and...then he'd shot his spunk and later felt rather guilty about such thoughts. He'd had that spanking-fantasy a few times but had generally tried to push it out his mind. However, he was fifteen and full of hormoness and couldn't be helped for having such fantasies with the females he was closest to. He'd lost his virginity a few months ago, with a girlfriend in his class at school, who he'd since fucked a few more times before they'd broke up last week. Naturally, his teenage libido was not satisfied with the half-dozen fumbling humps with his girlfriend when her parents had been out. His mind still raced with fantasies, espcially now that he and his girlfriend had split up. Billy found himself sometimes thinking back to when he was ten and he and his sisters had shared a bath on holiday, agreeing to show each other their parts. The innocence of the incident notwithstanding, it often found itself creeping into Billy's mind when he whacked off.
He was still pondering such things when he found himself in the kitchen. He noticed the tiled floor had footprints around it, slightly damp and clearly made by barefeet. Little ones. Clearly his sisters had been in here in their barefeet. Very odd. He was sure they were wearing socks earlier. Billy's stomach then grumbled with hunger and, his distracted thoughts pushed aside, he went over to the food cupboard.

Britney and Sarah came downstairs soon and sat and watched TV with their brother. Their father, Mike, returned at four and they had dinner and generally sat around the house up to their usual things - Mike watching TV and relaxing with a couple of beers, Sarah and Britney sitting on the floor also watching telly (their dad noticing that his daughters, for the first time in years, were holding hands as they sat there) and Mike was upstairs playing online computer games.
The girls went to bed at nine-thirty and lay talking quietly until their dad and brother had gone to their respective rooms for the night an hour later. At that point, Sarah turned on her lamp and Britney slid nude out her bed and came over to Sarah's. They quietly masturbated each other and kissed for an hour then slept in their own beds, having decided they couldn't risk being caught in bed together in the morning.

Sunday

It was soon raining that evening and Billy, on his bike zooming round the suburbs, decided to come back early. The light was fading anyway. He parked his bike in the garage then slipped into the house, taking off his jacket and glad that he'd missed most of the rain, his hair slightly damp but his jeans and black jumper were fairly dry.
Billy saw that neither of his mischievous little sister's were in the living room, although the TV had been left on. He went up the stairs, glad to see through the open door into his computer-room that the girls were not in their either. He didn't mind them using his computer, but they did have a knack of screwing things up without meaning to.
Sensing the girls were in their bedroom, Billy decided to surprise them for a laugh. A grin appeared on the fifteen year old boy's charming face and he tip-toed down the hallway to Britney and Sarah's door. He placed his hand on the handle, push it down and strode into the room, his amused facial expression quickly turning to blank shock when he saw his twin sisters kneeling opposite each other on Britney's bed, naked. They looked round at the intruder, Britney's big blue eyes and Sarah's big green eyes full of shock, quickly withdrawing their hands from between each other's legs.
"Billy?" gasped Sarah.
"Er..." stammered their brother.
"Can't you knock?" Britney asked, fearfully, raising her hands to cover her budding breasts, in the process just drawing her brother's attention to them.
"Uuh, sorry," Billy said, and he stepped out the room and closed the door. If he'd caught them naked because they were getting changed, he'd just be very embarrassed, but though he was blushing now he mainly felt intense curiosity given that what the girls had been up to was clearly not particularly innocent! They'd been feeling each other, Billy was certain. Sarah and Britney's reflexes had not been as quick as they'd have liked, Billy having caught a glance of his sister's with their hands between each other's legs because they'd had a chance to react. There was no doubt that the girls had been frigging each other! Billy couldn't move, standing there and wondering how he'd be able to look at the girls again having seen what they were up to. He was even more alarmed to realize that his cock was incredibly stiff in his pants!
Inside the room, Sarah got off the bed, reaching down to retrieve her clothes, muttering "Shit, shit, shit."
"Well, our secrets kind of er...out, now," Britney said, and she giggled.
"It's not funny!" Sarah insisted, quietly, then despite herself she sniggered.
"Shit, did you see Billy's face?" whispered Britney.
"Why are you whispering?" whispered Sarah.
"I think he's still out there. I haven't heard him walk away."
"Poor guy. He probably thinks we're a pair of lesbian sluts!"
"We are."
They both giggled.
"Hey, let's get him to join in!" Britney suggested.
"What?" Sarah gasped.
"Well...he can't tell dad, or indeed anyone, about us if he's been a partner in crime! It'll seal his silence."
"Good point. Plus...it might be fun."
"It will be fun! I haven't seen a teenage boy's thing, not in the flesh. I think it'd be cool to see a guy jack-off. Let's ask him to join us, a bit of mutual-masturbation."
"Okay," Sarah said, after a second's contemplation. She and her sister had always thought Billy was a handsome boy, much nicer than any other boy's they knew. Getting acquainted with a boy's 'parts' would be fun, and their brother the ideal choice.
Brintey got up - still naked, like her sister - and went to the door. She opened it and saw Billy standing with his back to her. He turned, saw Britney was wearing nothing but a big grin, and averted his eyes.
"Don't be silly," Britney said, "you can look. You've already seen us nekked anyway! Come in."
"Come what?" said Billy, looking into Britney's eyes, trying not to look down at her lovely pre-teen body.
"Come in silly. Come into our room. Bring that big stiffie with you!"
Billy realized his erection could be made out through his jeans, but there was nothing he could do to hide it. It didn't seem necessary anyway, it certainly hadn't bothered his sister. Britney turned and walked into the room, her brother unable to resist looking at her cute bare ass before he followed her in, shutting the door behind him.
"What were you up to?" he asked.
"Just playing with each other," Britney shrugged, sitting on the bed, Sarah next to her.
"Literally playing with each other," Sarah added with a grin.
"Oh," was all Billy could think to say.
"Do you want to join us?" asked Britney.
"Yeah, go on," Sarah urged Billy, "It'll be fun! We've been having fun together since yesterday. Masturbating is fun on your own but even better with someone else!"
"Well, I dunno," Billy said, "I could get in trouble, playing around with you two."
"Don't worry, no-one will find out, certainly not from us," Britney reassured the boy, both sisters realizing that Billy's hesitation was purely down to being worried about getting caught.
"Okay," smiled Billy, "Er...what shall we do?"
"Well," began Sarah, "you can begin by getting undressed. You've seen us naked. Let's see you!"
Billy took off his jumper, then undid his jeans. He slid them off, followed by his socks, and finally his shorts so that all three siblings were nude.
"Whoa, it's bigger than when we last saw it in the bath all them years ago," grinned Sarah, her and her twin looking at Billy's stiff prick. He had a small amount of brown pubic hair, jutting out of which was his erect adolescent cock, seven-inches in length, thick and with veins running up the shaft. The end was bright purple and swollen.
"I'm surprised you remember that time in the bath," Billy smiled, "when we showed each other our privates."
"We remember it well," Britney said, "Join us on the bed Billy."
The boy did so, kneeling on the bed so that he faced his younger sisters, who knelt side by side, their thighs slightly parted.
"You're pussies don't look much different yet," he commented, "No hair as yet."
"We'll get hair," Sarah insisted, "Sometime anyway. Like our boobs? We didn't have them when we were seven when you last saw us nekked."
"They're nice," Billy commented, eyes glancing at each Sarah and Britney's small titties, "They'll grow nice and big I reckon."
"I hope so, all boys love big boobs," Britney said.
"Well, I like them at their current size," Billy insisted.
"Wanna feel?" asked Sarah.
"Okay."
Billy reached out and tentatively placed his right hand over Sarah's left tit, gently groping that small mound of flesh, feeling the nipple stiff under his warm palm, his sister sighing a little with pleasure. He then reached out with his left hand and placed it over Sarah's other breast and he had a good feel before doing the same to Britney. Both girls had loved each other's physical attentions, but being touched by a boy - especially their dear, handsome big brother - was very new and exciting for them. As Billy played with Britney's tits, Sarah sat back, unfolding her legs from under her bum and stretching them out in front of her, spread them and watched Billy's eyes flick down to her bald slit.
"Like my pussy Billy?" she asked.
"Nice," Billy said, taking his hands from Britney's tits, that girl copying Sarah in sitting back with her legs out before her and parted, their brother sitting before them, still kneeling with his erection bobbing in the air. "They still look like little slits, but I can see the lips are more developed. And you're clits have grown a bit."
"Yeah, playing with them makes us cum," giggled Sarah, "We started doing it to each other yesterday, frigging each other. Do you want to frig us Billy? You can see if you can make us have orgasms, won't that be fun seeing a girl have an orgasm?"
"I've seen a girl cum," Billy said, proud.
"Yeah? Who?" asked Britney.
"Jenny, the girl I went out with," her brother explained, "The one who I split up with last week."
"You screwed her? Cool," Sarah grinned, "So you're not a virgin then! Very grown up."
"I made her cum a couple of times I think when I had sex with her."
"Do you think you could make us cum by fingering us?" asked Britney.
"I could try."
"Try it," Sarah said, parting her legs a bit more. Billy moved over and knelt between the girl's legs, looking down at her slit. He'd fucked his ex-girlfriend, Jenny, a dozen times but they'd been furtive fucks, hurried and sometimes with both of them not having time to take all their clothes off. Though he wasn't a virgin, Billy was hardly a fully-experienced gigalo and sex was very much a novelty, as was being able to take his time admiring and exploring his two sister's sexy little bodies. He licked his lips, a look of concentration on his face as he reached out with his right hand and placed the tip of his forefinger to Sarah's slit. The lips were slightly moist and Billy fairly easily pushed his forefinger into his sister's pussy.
"Nice," Sarah said, "Mmmm. Rub my clit too."
"I know, I know," said Billy, "I fingered Jenny once so I'm not a complete amateur." He reached out with his other hand and rubbed Sarah's clit with his thumb whilst adding a second digit into the girl's cunt. He buried them into the knuckle and moved them back and forth, rubbing her clitoris all the while, exchanging smiles and eye-contact with Sarah, glad that he was clearly giving the girl a thrill. Britney was watching this carefully, sometimes glancing down to Billy's stiff looking dick, delighting at the sight of that fascinating, hard rod of boy-flesh.
"That's good," Sarah was saying, her voice breathy with lust, "Finger me harder Billy! Harder! I'm not totally delicate my dear brother."
Billy began working his two-fingers back and forth in his sister's tight hot cunt, energetically rubbing the girl's clitoris.
"You like that?" he asked Sarah.
"Mmmm! Yeah!"
"Stick your finger in her bum," Britney giggled, "Go on! Sarah did that to me when she was licking me out earlier."
"Licked you out?" asked Billy.
"Yeah," Britney said, "We've er...done a bit more than just play with each other. We licked each other's pussies! Maybe you can try that soon. Anyway, Sarah stuck a finger up my ass earlier whilst licking and fingering my twat. It felt nice! Try it on her."
"I haven't got any spare fingers," Billy smiled, pushing two fingers up Sarah's cunt whilst his other hand was used to rub her budding clit.
"I'll do it then," Britney said, and she reached between her sister's thighs, under where her brother's hands were busy at Sarah's twat, and she pushed a finger between Sarah's buttocks. She nudged her anus with the tip of her finger.
"Oooh," yelped Sarah, "It won't go in dry. Try a bit of lube."
Britney took her forefinger from between Sarah's legs and sucked it, then put it back up to Sarah's anus. It slid in with just a bit of pressure, in to the second joint.
"Aaah, that's nice," Sarah said, "I was saying to Britney earlier that I often put a finger up my ass when I masturbate myself."
Billy smiled, loving this complete openeness between him and his sister's now as he fingered Sarah's pussy whilst Britney slid her forefinger up to the knuckle into Sarah's ass. Britney wiggled her finger around in her sister's rectum, Sarah now panting deeply with pleasure.
"She'll cum soon," Britney commented to Billy, "You watch Sarah! She's about to climax, she's beginning to blush, her eye-lids are fluttering."
"Mmmm," Sarah panted, "Oh yeah, that's good Billy! Frig me, harder! Britney, my love, slide that finger deep into my ass!"
Her brother and sister worked between her legs quicker, Sarah's legs quivering, her face growing flushed.
"Uuuh, uh, I'm cumming. Aaah! Oh yeah, uuuh."
The twelve-year-old angel slumped back, tossing her head from side-to-side and groaning with ecstasy whilst Billy and Britney showed no mercy, working Sarah's two orifices with their busy digits. For over half-a-minute Sarah was in the grip of total physical pleasure, and when she finally came down from her apogee, Billy took his fingers from her cunt and Britney tugged her finger from out of her sister's ass. Sarah sat up.
"Thank you, that was great," she grinned, brushing some of her golden hair from her eyes.
"It was fun doing it," Billy said. Britney agreed whilst feeling compelled to sniff her forefinger and giggling like a kid.
"Your turn," Sarah said to her twin.
"Hooray," Britney cheered, laying back, propped up on her elbows and looking down as she spread her legs. Billy knelt between her thighs and repeated his earlier actions with his other sister. He slid a finger, then two, into Britney's tight bald cunt then rubbed her clit with the thumb of his other hand. Britney was smiling and soon panting with pleasure. Sarah sucked on a finger and reached under her twin, sliding the digit up Britney's anus to the knuckle.
"Ooooh, yeah," Britney panted, "Mmm. That's so good!"
"Look at her nipples," Billy said, "Britney's little nips are like bullets."
Indeed, those red tips on her small boobs were very stiff. Whilst continueing to wriggle her finger up into her sister's rectum, Sarah leaned over and took one of Britney's nipples into her mouth and sucked. This enhanced Britney's pleasure even more, and as he frigged the girl, Billy was delighted at this sight! He recalled Britney admitting that Sarah had licked out her cunt previously and the image of this turned him on even more. He hadn't touched his cock - or had it touched - since getting onto the bed, and his organ was as hard as steel and felt as if it go off and shoot his sperm without having to be touched!
For now, though, he and Sarah concentrated on Britney, fingering and frigging that beautiful young girl for a good ten-minutes until she climaxed rather loudly. "Oh yeah, I'm cumming, finger me. Uuuuh! Billy! Sarah! Finger my holes, uuuuh! Oh yeah, oh God!"
She finally slumped back, spent from her climax, her siblings taking their fingers from her holes. Britney knelt up and leaned over, giving Billy a peck on the lips, then turned to Sarah did the same. All siblings were feeling very close and happy with each other, Billy's earlier shock when he'd discovered his sister's masturbating each other, totally gone. He was perfectly comfortable sitting here with them, all three naked.
"Your turn now dear brother," said Sarah, her and her twin sister looking down at Billy's erection.
"It won't take long for me to shoot my load," he smiled, "I'm so turned on!"
"Then lets get to it!"
Billy lay on his back along the center of the single-bed, his sisters on both sides of him. The teenager's cock lay across his hard belly like a seven-inch rod of cock-shaped steel. With complete confidence, Britney reached out and clasped her brother's tool in her small hand, wrapping her fingers round the shaft and holding it upright.
"Wow, it's hard as nails," she grinned.
"Let's feel," Sarah said, reaching out also, gripping the upper part of her brother's penis in her hand, Britney's fingers clasping the base of it.
"What do we do?" Britney asked her brother, "Just stroke it?"
"Yeah, just pump your hands up and down, rolling the foreskin back and forth."
The girls did so, matching their movement so that they pumped up and down at the same time. Billy was in utter heaven! Two fists pumping his prick at the same time with a perfect rythm. As he'd expected, his climax began to boil up fairly quickly. He breathed deeply, moaning with pleasure, his sisters increasing their pace as they sensed the critical moment approaching.
"Here it is," Billy cried proudly and he let out a long sigh of joy. His sperm erupted out, Sarah and Britney watching in awe as big cock they were both pumping rapidly began spurting thick wads of creamy sperm into the air, the wads splashing down on Billy's torso.
"Wow," grinned Sarah as one spurt almost reached a foot in the air before it arced down and splashed onto Billy's stomach. The final loads of cum just oozed out of his piss-hole, the slimy outpourings running over Sarah and Britney's fingers.
"Bit more spectacular that your climaxes," Billy smiled, sperm splattered over his belly.
"A bit messier too," Sarah said, taking her hand from her brother's cock and looking whistfully at the sperm that dripped from it. Britney did likewise then reached out with her sticky fingers and idly swirled the tips through the splashes of cum on Billy's body.
"That really was fun, thanks girls," said the boy as he sat up.
"Yeah, it was cool," Britney agreed.
"We could do it again sometime," Sarah added.
"Dad'll be back soon," her brother said, "I'd better lock the front door, that'll delay him."
"Okay."
Billy got up, and went out the room. He nipped to the bathroom and wiped the cum off his stomach with tissue, feeling excited at the events that had just taken place. He then went back to the girl's room, put on his clothes and then went into the hallway, when he heard the front door opening!
"Dad's back," he whispered as he ducked back into his sister's room.
The girls sprang off the bed and began dressing, Billy going downstairs and greeting his father whilst the girls upstairs made themselves look respectable.

During the course of the evening, Sarah had told Billy to come to their room late that night. He agreed, naturally.
At eleven-thirty, with their father having gone to bed half-an-hour ago, Billy crept down the hallway and into his sister's room. Britney and Sarah, their naked bodies illuminated in the soft glow of the lamp-light, were on Britney's bed. Billy closed the door quietly behind him and slid out his boxer shorts then hopped onto the bed with his sister's, his cock already semi-hard as it had been whilst he'd lay in bed waiting for the coast to be clear.
"Hiya kids," he grinned at Sarah and Britney.
"Glad you could make it," smiled Sarah, "Ready for more of the same fun?"
"Absolutely."
"We'll have to keep the noise down though," Britney warned her siblings, "No loud groaning and moaning!"
The others giggled.
"Let's get this nice and stiff first," Sarah said, reaching over and wrapping her fingers round her brother's cock. She stroked it firmly in her small fist, Billy's dick responding quickly, soon fully hard and stiff.
"I'll frig you two first," the boy shortly said, "Then you can do me!"
"Okay," Sarah said, "Me first." She took her hand from her brother's prick and sat back, legs apart. As before, her brother and sister worked on her at the same time.
"I wanna finger her ass this time," Billy said to Britney, "Why don't I work on her ass and pussy, and you rub her clit."
"A fine idea bro," said Britney.
Billy sucked on a forefinger then reached under Sarah and slid the digit up into her tight bum. Then he pushed two fingers from his other hand into her hairless little cunt. Britney enthusiastically began rubbing her twin's clit with the tips of her fingers, Sarah soon sighing deeply with pleasure. They kept a listen out for their dad but Mike was a heavy sleeper. He was slumbering peacefully in his bed, unware of what activities his kids were up to!
After five-minutes, Sarah had a delightful climax, slumping back on the bed and moaning quietly with joy as Billy and Britney frigged her cunt and asshole.
Then it was Britney's turn. Her brother slid a finger up her bum and two fingers up her cunt then Sarah rubbed her clit. Sarah also sucked on one of her sister's nipples, Billy deciding to copy her. With both holes being fingered and each tit being sucked, it didn't take long for Britney to cum.
Finally, Billy's turn came.
"I'm so horny," he said, kneeling up with his cock sticking erectly upwards, "I'll cum in no time!"
"Goody," grinned Britney, flushed from her own recent orgasm, "I love seeing your sperm fly out! It's cool."
She gripped her brother's cock and began pumping it, Billy half closing his eyes in pleasure. Sarah reached out and stroked her brother's balls, feeling them gently, licking her lips and thinking of all the lovely gooey spunk in those things, ready to shoot out.
"Here it is girls," Billy panted, "Ready?"
"Yeah!" the twins said, eagerly.
Britney pumped Billy's cock faster and the eruption occured, thick streams of sperm ejecting out. Billy let out a long sigh as his pent-up spunk geysered forth, landing onto his thighs and groin, a few dollops landing on Britney's forearm.
The girl masturbated Billy's dick after the flow of sperm had ended, feeling it soften, before she finally moved back.
"You give a good hand-job sis," Billy smiled.
"Thanks," Britney said, proudly.
"Better wipe your hand off," Billy said, grabbing a tissue from the bedside cabinet and wiping the white sitcky fluid off his thighs.
Britney looked at her forearm, which had two splatters of spunk on it. Then she bought it up to her face and flicked her little red tongue out and licked up some of the sperm, swallowing.
"Mmm, salty," she grinned.
"Britney!" gasped Sarah, a look of horror on her face which quickly turned to curiosity, then amusement, "Let me have a go."
Britney offered her forearm to her sister, Sarah licking off the other blob of semen.
"Yeah, salty," she concluded with a grin, "Warm too. Mmmm."
Billy just blinked, wondering at just how far his little sisters would go!
"We can do this in the morning," Billy said, "We've got six-weeks vacation ahead of us and dad'll be at work every weekday. We'll have loads of time to play around together."
"Yeah, it'll be great!" Sarah agreed.
Billy felt tired. He said his farewells then tip-toed out the room and into his own bedroom, falling into a peaceful sleep quickly, as did Sarah and Britney in their own beds, all the siblings looking forward to the morning.

Monday

Billy got up early, dressed, and chatted to his dad over breakfast. The girls were still asleep. Once his father had left for the day at eight o'clock, Billy hurried upstairs and knocked on his sister's door.
"Enter, dear brother," called Sarah.
Billy came into the room, spying Sarah sitting up in bed, nude, the covers only up to her waist so her bare torso and titties were on display. Britney was also awake, just sliding out of bed, also naked. She stood and stretched, yawning dramatically.
"I heard dad's car just drive away," she said, "Cool! We're all alone."
"Time for some fun," Billy said, stripping naked, his prick erect already.
"Let's go to your room Billy," Sarah said, "It's got a bigger bed."
"Yeah, good idea."
And so, they went into Billy's room. He had a big double-bed, the room facing East so the bright morning sunlight streamed in through the big window. He had posters of female popstars on his walls, along with shelves and shelves of books. Sarah clambered onto the bed.
"I think we should try oral," she said, as Britney joined her on the double bed.
"Oral?" quizzed Billy, excited.
"Yeah, you ever had oral?" asked Britney, "Or done it?"
"No," her brother replied, deciding not to lie, "Jenny didn't offer and I didn't ask."
"Well, now is your chance!" Britney said as Billy sat on the bed next to her, "Lie back Billy."
The youth did so, laying on his back whilst his twin sisters knelt either side of his hips.
"Neither me or Britney have sucked a cock before," Sarah said as she held her brother's impressive erection upright, "so tell us if we do something wrong."
"I've never had my cock sucked," Billy smiled, "so I won't really know if you're doing something wrong! Just go for it. You'll do fine. Then I'll lick out your hot little pussies."
Spurred on by such a promise, Sarah and Britney both leaned down together, bumping their heads. They grinned.
"You first," Sarah said.
"Thanks," said Britney, and she leaned in and clamped her warm wet lips over Billy's swollen glans. She sucked, moving her head down, taking a few inches of Billy's penis into her mouth.
"That is good," Billy sighed, "Oh yeah, that's nice!"
Sarah leaned in and found enough of Billy's shaft accessable to run her tongue over it, licking the base of her brother's dick whilst Britney took her hand away from it, just keeping Billy's prick sticking straight upwards in her mouth, slupring on the head. The girls make slurpy, smacking noises as they both work on their brother's tool. They switched over shortly so that Britney was licking the base of Billy's cock, sometimes sucking on his nut-sac, whilst Sarah sucked on the head.
Billy felt his sperm boiling up after just a few minutes. He felt so damn horny laying here, nude, his pretty twelve-year-old twin sisters sucking and licking his cock.
"I'll be shooting soon," he said. He felt it only fair to warn them, but the girls seemed enthusiastic about the prospect of drinking their brother's spunk, which Billy had not anticipated. He'd thought they'd move out the way. However, Britney slurped deeper on his cock whilst Sarah knelt up.
"You get the first few spurts," Sarah said to Britney, "I'll get the rest."
"Uuuh, I'm cumming," Billy groaned, "Fuck...uuuh!"
His first wad of sperm shot out into Britney's mouth, and she swallowed it down before the second squirt arrived. She gulped that down too then took Billy's dick from her mouth. Sarah leaned over, gripping Billy's prick, but she didn't get down fast enough, the third spray of cum shooting up into her face and streaking over her left cheek. Then she got her lips down over Billy's organ and sucked the remaining shots of salty jizz, and like her sister she swallowed every drip.
"That was nice," Billy said as Sarah finally knelt up, "Now I'll return the favor."
With the taste of their big brother's cum in their mouths, the girls were excited at this prospect. Britney elected to go first, laying on her back and spreading her legs, between which Billy knelt and leaned down. His sister's bald wet pussy was there for his attention. First he ran his tongue up the pink slit a few times, Britney responding favorably. Billy then pushed his tongue into the girl's cunt, feeling her tense a little with pleasure. He took out his tongue then pushed it back in, repeating this a few times before getting in there properly. He wiggled his tongue up into her cunt-canal, feeling how hot and moist it felt in there, his mouth lips pressed to her pussy lips.
"Oooh, suck me," Britney was panting, "Mmm. That's good Billy, yeah."
Sarah - a string of cum still slashed over her face - lay alongside her sister, sucking on her nipples in turn, Billy busy eating out Britney's cunt. Britney's toes flexed and curled, her eyes closed as she swam in pure pleasure. Billy really liked licking his sister out, enjoying the taste of her virgin pussy. Knowing the girl's desire for attention to her anus, he bought his right forefinger into play, easing it up into Britney's asshole to the knuckle whilst he continued to slurp at her pussy.
"Oh, I'm cumming," Britney shortly cried, "Uuuh, yeah! Billy...uuuuh, that's good. Aah. Oh yeah!"
Sarah sucked on her sister's right nipple whilst pinching the left one lightly between her thumb and finger. Billy waited until Britney had finished her orgasm before he finally knelt up, smiling, pussy juice round his lips, his cock re-stiffening already.
"My turn," Sarah smirked.
Soon, she was laying back. Billy sucked her cunt and fingered her asshole, Britney rubbing Sarah's clit whilst sucking on each of her small titties. In just five-minutes Sarah was climaxing, running her hands through Billy's hair as he busily worked between her legs with his tongue. Britney took her mouth from Sarah's nipple and kissed her sister, the twins snogging hard as Sarah climaxed. When Sarah's orgasm had died away, Billy knelt up stroking his erection and watching his sister's kissing deeply before they moved apart.
"Fancy a kiss?" Sarah said, kneeling up and facing her brother.
"A snog?" Billy said, frowning, "But your my sister."
Britney giggled. "We've frigged each other and we've sucked your dick, it's hardly going 'too far' to kiss."
"I guess," Billy said. He'd been briefly jealous when he'd seen the girls snogging and suddenly couldn't understand his initial reservations, "Okay, let's kiss."
Sarah smield then leaned forwards, clamping her lips to Billy's. They frenched deeply, their tongues sliding into each other's mouths. Billy had kissed girls before, but he found that it was even more exciting now. At first he'd thought it would be freaky, snogging his own sister, but if anything being brother and sister made it more exciting! Sarah shortly pulled back.
"You're a good kisser," she smiled, "Just as good as Britney."
"I'm sure," Billy smiled.
Britney quickly leaned in and started snogging Billy, both of them sucking on each other's tongues. For a full minute they snogged before they moved apart.
"I'm hard again," Billy stated, "I think I'll blow my nuts. Shall we frig each other off together? I'm sure we can manage that."
Billy directed his two sisters to kneel near him so that they formed a triangle, facing inwards. Billy reached out and thrust a couple of fingers into Britney's cunt. Britney reached out and fingered Sarah's cunt, leaving Sarah to reach over and pump Billy's cock in her fist. They masturbated together in unison. The girls climaxed together, Britney enduring her cum whilst still pumping her brother's cock, Billy soon spurting his sperm all over his thighs and onto Britney's forearm.
The three siblings had a bath together, giggling and splashing about, washing each other and practising more kissing. It was a free-for-all, Billy snogging his sisters in turn or just sitting back and getting a kick out of watching Britney and Sarah snog each other.
Once they were dressed, they had breakfast. The girls took a stroll outside to the shops and Billy went off to use his computer like he would on any normal school-free day.

Sarah and Britney were home at lunchtime. Billy was sitting in the living room, watching TV.
"Hiya Billy," said Sarah, sauntering into the room, her sister close behind her.
"Hi girls," their brother said. He appraised the girl's looks. They'd kicked off their sneakers and were just in their white sports socks. Sarah wore a pale yellow summer-dress, loose and reaching only half-way down her bare thighs. Britney was in a tight pink T-shirt and white jeans. Both girls had their flowing blonde hair hanging loose.
"Anything on?" asked Britney.
"Not really," Billy said, flicking the TV off and standing up, "Nothing more enjoyable than what we can get up to! Who needs TV?"
"Excellent," Sarah said, stepping up to her brother and, on her tip-toes, giving him a peck on the mouth, "I'm feeling horny."
"Me too," giggled her sister, also stepping up to give her brother a kiss.
"Well, as you girls are so affectionate perhaps you'd like to er...submit to a little request. A little fantasy."
"Oooh, sounds interesting," said Britney.
"Come on," said her sister, "Tell us what it is Billy."
"Well...er..."
"Don't be shy," Britney said, putting an arm around her brother's waist, "There can't be any secrets between us, not after all we've been up to since yesterday."
"Well," Billy began again, "I want to spank you two."
"Spank us," gasped Sarah in mock horror, "What have we done?"
"Nothing," Billy insisted, "It'd just be...fun. You remember that time last year, when you deleted some stuff off my computer? One of you - I think it was you Britney - bent over and offered to be spanked. Only jokingly of course. But anyway...I kinda fantasized about that for a while. I think it'd be sexy."
The girls looked at each other and smiled. Their dad didn't believe in corporal punishment so neither girl had been spanked before, as punishment or otherwise. They didn't view it as something to be frightened of, and the twins exchange of smiles communicated to each other that to both of them the idea of Billy's sounded like fun!
"Okay," they said together.
"Not too hard though," Sarah insisted.
"Don't worry, I won't hurt you two. Okay, who's first?"
"Me," Sarah said, "Shall I strip?"
"No," Billy insisted, "It'd be better if you just lifted your skirt up and let me pull down your panties."
"Hmmm, a very specific request," the girl smiled, "Your fantasies of this were clearly detailed."
"Come on," urged her brother, "Stand in front of the sofa. Like I said, I won't hurt you. Not much. Just say if you want me to stop."
Sarah was feeling very excited by this. Like Britney and Billy, she viewed the recent events as erotic, but also approached them with a sense of fun, like they were just games. Which effectively they were.
Sarah stood in front of the sofa and reached down to the hem of her yellow cotton dress, pulling it up and holding the bunched end around her waist so that she was exposed from the waist down, standing there in her white socks and matching white panties.
Licking his lips, with his cock as stiff as a post in his jeans, Billy reached down from behind Sarah and hooked his thumbs in the waist-band of her panties and slid them down, letting them fall to the girl's ankles.
"Bend over," he said, and Sarah did so, still holding up her dress as she leaned forwards, her cute pale butt sticking out.
"Spank that ass," grinned Britney, feeling pretty turned on herself as she stood nearby watching the proceedings.
Billy flattened out his palm, pulled back his arm then swung forwards. A resounding CLAP rang through the room as he whacked Sarah's ass fairly firmly, but not too hard.
"That okay?" he asked his younger sister.
"It was okay," she confirmed, "Do it again!"
Billy did so. CLAP! Sarah felt a rush of pleasure from the act, the sharp sting as her ass was hit by her brother's hand feeling strangely enjoyable. CLAP! CLAP! Billy smacked Sarah's ass a dozen more times, those little cheeks quivering with each spank, the pale flesh a glowing faintly red by the time he stopped for a breather.
"That feels quite nice," Sarah breathed, "Spank me more! Not too hard though, just about the same strength as you've just done."
"Then it's my turn," Britney said, eager to be spanked by her brother also.
Billy smacked Sarah's bum another five times, Sarah emitting little yelps which were partly pain but mostly pleasure. When Billy finally finished, his arm tiring a little, Sarah let the hem of her dress fall back into position and she stepped aside.
"That was good," she said, "It felt kinda nice. A bit sore, but in a nice way."
"It was fun for me too," said Billy, unzipping his flies, "Look how stiff I am!"
He tugged out his prick and sure enough it was rock-solid, the purple head throbbing brightly.
"My turn now," said Britney, impatient for a smacking. She stepped up to the sofa and stood there. "Yank my pants down and smack me Billy! Pretend I've been a really naughty girl!"
"You are a naughty girl," smiled Billy reached from behind her to undoe the buttons on her jeans to enable him to slide them down to her ankles, "Very naughty! Masturbating with your sister and brother! And sucking cocks and eating pussy. Time for a smacking young lady."
Britney giggled as her brother then tugged her panties down to her ankles, and she leaned forwards with her hands flat on the sofa, bent right over with her bum thrust right out. Billy proceeded to smack the girl's buttocks with the palm of his hand. SMACK! SMACK! SMACK! SMACK! Britney felt the same as Sarah had, namely a sharp sting from her spanked buttocks which was incredibly pleasurable and arousing at the same time. Sensing that Britney, though a little smaller than Sarah, was more resiliant than her twin, Billy spanked her for longer.
"Mmm, keep spanking me," Britney panted, "Uuuh, that's nice."
Billy continued smacking the girl's bum whilst Sarah knelt down and gripped his cock which jutted from his open flies still. She leaned in and sucked on it, slurping on the fiery tip. Billy was incredibly turned on as it was and after smacking Britney's ass a few more times he felt his sperm rising.
"I'm gonna blow," he announced, "Sarah! Jerk me off on Britney's behind, I'll sooth her smacked bum with a shower of spunk!"
Sarah took her brother's cock from her mouth to allow him to move round so that his cock was thrust right at Britney's reddened buttocks. Sarah pumped Billy's dick, her fist a blur as she whacked him off. Billy let out a long groan of pleasure as his spunk erupted, the thick wads of sticky white fluid spraying all over Britney's ass-cheeks. They were slightly spread, allowing a sticky wad to spurt right between her cleft and onto her pink, puckered anus which twitched. She loved this, the lovely smacking she'd got now contrasting with the cooling spray of cum over her ass-cheeks. When her brother's geyser of spunk finished, Sarah wiped Billy's cock-head over Britney's sperm-slimed buttocks, squeezing out the last oozing wads over her sister's tender, reddened flesh.
"That's something we'll have to repeat sometime," Billy smiled, finally stepping back and slumping into an armchair.
"Yeah, that was fun!" Sarah grinned, standing up.
"Don't rest just yet," Britney said to her brother as she stepped fully out of her jeans and panties, "You need to take care of us! We want licking!"
"I'm tired," Billy moaned, "Can't you take care of each other?"
"Men eh?" tutted Sarah with a smile, "C'mon sis. Let's do each other, we can put on a show that might give our poor brother some energy back."
"Why don't you sixty-nine?" suggested Billy. The girls blinked with confusion, unaware of what he meant. So, Billy, like the knowledgable brother he was, explained the activity to his sisters. He steered them in the right direction and soon, as he sat back in the armchair stroking his semi-hard dick, Sarah and Britney were in a sixty-nine on the floor. Sarah was below, Britney on top, both girls loving this activity, slurping thirstily on their sister's pussy whilst receiving the same treatment. The living room was filled with the sounds of the girls moaning with pleasure and the wet slurpy sounds as they ate each other out.
Billy was quickly erect once more, his cock hard and proud in his fist as he masturbated and watched his sisters sixty-nine on the floor. After ten-minutes he was feeling a bit left out, but the girls now very much considered their dear brother a part of their intimate little 'fun' now. They soon parted and got up, walking over to the armchair on which Billy sat. They sat on an arm each, putting their arms round their brother as he jerked off.
"Fancy some more fun?" Sarah asked him.
"Sure," Billy replied, "Why don't me and you sixty-nine? Then I'll do it with Britney."
Billy got down on the floor and Sarah mounted him, inverted, lowering her bald wet pussy onto his mouth whilst she lowered her head and took her brother's dong into her throat. She slurped deeply on his cock, more confident now, whilst Billy, also more confident at his abilities, ate out her pussy. He dug his tongue up into her snatch, reaching up and clapping his hands to her bum-cheeks and sucking her cunt. All the while Sarah was bobbing her head and moaning with pleasure with Billy's dick down her gullett.
After a short while, Sarah got off, tired, and Britney took her place. She was soon on top of her brother, sucking deeply on his cock and bathing it in her wet tongue whilst Billy turn lapped at her pussy from below. He wiggled his tongue up their, slurping noisily. Sarah knelt down nearby, behind her sister, Britney's spread ass before her and Billy underneath it sucking the girl's cunt. Sarah was planning on fingering Britney's asshole but instead she decided to lick it, leaning in and running her tongue up the cleft. Britney had been expecting a finger up her butt so having it licked was a surprise, a really nice one! She squirmed on top of her brother, emitting a muffled moan of joy, still sucking on Billy's organ. Sarah worked on her sister's asshole thoroughly, running the tip of her tongue round the anus then getting more confident and sliding it in. Billy was loving this too. As he ate out Britney's moist cunt he had a perfect close-up view of Sarah's tongue pushing in and out of Britney's clenching asshole. It aroused him further, his cock stiffening even more in Britney's sucking mouth.
Sarah eventually knelt up and placed the tips of both her forefinger and index-finger to her sister's saliva-slick anus and squeezed them in. Britney hadn't had two fingers up her ass before but she was able to take them, her sphincter sucking tighly on Sarah's two digits as she slipped them into her twin sister's rectum to the knuckle.
This bought on Britney's climax and she wriggled delightully on top of Billy, his tongue in her twat and Sarah's two fingers up her asshole. Billy began shooting his load a minute later, spewing thick creamy sperm into Britney's mouth. She gulped it all down, loving the taste and sucking on Billy's prick even when the flow had ended to get every last drop.
Sarah finally slid her fingers from her sister's ass, allowing Britney to take Billy's wet flaccid cock from her mouth and dismount him. They all lay back, tired and grinning.

They had lunch afterwards, then sat around watching TV in the nude. Their father was due home at five, so with plenty of time spare they had more fun. Britney and Sarah let Billy spank them, though not as much this time as their bottoms were still a bit sore from earlier. Billy licked out his sisters one at a time as they sat back on the sofa, then he sat down and the girls worked on his cock. Sarah sucked him to completion this time, drinking down all the spunk Billy fired down her throat, Britney meanwhile sitting next to Billy on the sofa and kissing him, pushing her tongue down his throat whilst her sister drank the boy's jetting semen.
They were dressed when their dad arrived home. The kids cooked dinner for their father, then they had a fairly normal evening. At night, with their dad in bed asleep, Sarah and Britney crept into Billy's room. They masturbated together, both girls climaxing before Billy took up the job of jerking-off in his own hand (literally), pumping his cock whilst kneeling up and directing the flow of sperm over Sarah and Britney's bellies as they knelt opposite him. After a quick wipe down with tissues the girls crept back to their own room.

Tuesday

As soon as Mike left the house for work, his three kids were in Billy's room. Billy was naked when his sisters came in, and they were just in their cotton panties which were quickly shed and tossed onto the floor.
They sat in a triangle again. Billy masturbated both his sister's at the same time, able to work a finger into each of their tight assholes and a thumb into their bald twats whilst they rubbed their own clits with one hand and masturbated their brother with their other hands, Sarah and Britney gripping Billy's cock at the same time and pumping it. They shortly tried some oral, the girls sucking Billy's cock (though not bringing him to orgasm just yet) before the boy licked each girl's cunts in turn.
They were all having a great time but Billy thought it was time to take things further.
"Say girls," he began, kneeling up as the sisters lay on their backs across the double-bed, "How about we do something different?"
"Like what?" asked Britney.
"Have sex?" suggested Sarah, sitting up.
"Yeah, how'd you know I'd say that?" said Billy.
"Well, it's the natural progression," Sarah shrugged, "I'd love to anyway! I'd like to give you my cherry Billy, my own dear brother!"
"Excellent," Billy smiled, "What about you Britney?"
"Yeah, I'm up for it," the girl smiled. She sat up and gave her brother a loving kiss, Sarah then doing likewise.
"You first honey," Billy said to Britney, the slightly smaller of the twins, "Lay back."
The girl did so, Sarah moving to oneside of the double-bed, kneeling up and lightly fingering her cunt.
Billy knelt between Britney's spread legs and nudged his cockhead against her bald pussy lips and began to apply some pressure. Britney's cunt, well licked and fingered, was nice and moist so despite the thickness of her brother's member, the virgin slit allowed surprisingly easy access. In a single thrust, Billy planted half his tool into the girl, who quivered with delight.
"Push it all the way in," Britney panted, her small hands flat on the chest of Billy who was over her, propped up with his hands flat on the mattress either side of his sister's shoulders.
"Here I go," Billy said, and he lowered himself some more, easing in the rest of his cock until it was fully buried in Britney's freshly deflowered pussy.
"Oh that's tight," he gasped, "Uuuh, oh Britney. What a hot little snatch!"
He lowered himself so that he was propped up on his elbows, his flat torso against hers, Britney locking her legs round her brother's waist almost as if she was desperate to prevent him from leaving her. Billy didn't have any intention of doing that. He planted a big wet kiss on Britney's lips then pulled half his cock from her slit then slid it back into her.
"Mmm, Billy, that's good," Britney panted, "That's so nice! Shaft me, baby, mmmm!"
"Is it nice?" Sarah needlessly asked, frigging herself as she watched from nearby.
"Oh yeah," Britney said, "So good! Billy is the best boy in the world to give my cherry to."
"You can have mine next," Sarah said to her brother.
"Billy leaned over and gave Sarah a kiss then gave one to Britney, who he was now fucking at a steady pace. He was driving his pole into her snatch firmly but gently, feeling his sperm rumbling up already. He had no chance of holding it back and decided to go for it, fucking harder and making Britney cry out with pleasure.
"I'm cumming," Billy gasped, "Fuck, oh yeah! Yeah! Uuuuh!"
His sperm exploded forth from his cock, the white fluid jetting into Britney's pre-teen womb, the girl nuzzling her head into Billy's neck.
"Mmmm, gimme your jizz," she moaned into his ear, Billy letting out a soft sigh as he finished oozing his semen into his sister. They held each other for a moment before Billy eased out of her and knelt up.
"That was lovely Billy," Britney said, embracing her brother and kissing him repeatedly on the mouth, "I couldn't think of a better guy to pop my cherry! Every girl should give her virginity to her brother!"
"I love you honey," Billy said, "You two, Sarah."
He embraced his other younger sister, kissing her lewdly, slipping his tongue into her mouth, "Now, if you would care to suck my prick I'll soon be in a state to deflower you Sarah."
Without hesitation, both girls went down on their brother, licking and slurping at his fine tool until, within a moment or two, it was erect once more. Britney moved aside and Sarah laid down.
"Careful now," the girl said as Billy mounted her.
"I'll be careful," he promised. He eased his cockhead into Sarah's pussy lips and paused, then slid forth. Sarah quivered with pleasure underneath him, her young twelve year old body tensing as her brother's prick slid up into her cunt. Then she relaxed, letting out a long sigh which Billy caught in his mouth when he sealed his lips to hers. They kissed passionately, Billy repeating his previous actions with his other sister as he slid half his cock out of Sarah's pussy before driving back in there. The girl tensed with pleasure, wrapping her arms round her brother and panting lustfully as she buried her chin in his shoulder.
"That's so good Billy, shaft me. Ram you lovely big dick in me! Uuuh! In my pussy!"
Billy fucked the girl steadily, driving into her gently at first before picking up pace. Sarah's pussy was lovely and tight and despite his previous activities Billy felt his cum begin to rise up after just a few minutes. He surrendered himself to such feelings, fucking harder and faster, Sarah climaxing beautifully beneath him. She kissed Billy deeply and thrust her tongue down his throat as he began spurting his boy-cum into her pussy. His cock sloshed thick slimy jizz into her young womb and Britney, too, climaxed, fingering herself wildly with a finger in her devirginated cunt and a finger in her ass as she watched he sister being deflowered. Billy groaned with pleasure as he emptied his nuts into Sarah's pussy, his little sister wrapping her legs round his waist as he drove into her to unload his cum in her pussy.
"That was nice," Sarah smiled.
"Likewise," Billy said. He kissed his sister lovingly then withdrew from her. He sat up, his cock limp and slick with cum and pussy juice. Sarah and Britney got up and kissed their brother hotly, taking turns to slide their tongues into his throat, before the beautiful twins kissed each other. The adolescent sibling's kissed and hugged for a few minutes before they finally got up. They all had a bath together and then, completely nude, they went downstairs for breakfast.

An hour later, still nude, Billy and his sisters were sitting on the sofa watching TV. Billy was in between Britney and Sarah. His hands began to roam, stroking each girl's thigh. Sarah reach out and gracefully clenched Billy's semi-hard cock in her small pale fist and began to lightly stroke it. Billy softly panted as his prick grew hard quickly, Sarah soon jerking off a very hard and very rigid pole. Britney held Billy's wrist and guided his hand to her pussy, her brother slipping a couple of fingers into that slit.
"Frig me," Britney commanded, "That's it Billy, frig my cunt. Mmmm. My nice deflowered cunt!"
Billy worked his two digits into Britney's twat to the knuckle, his sister squirming delightfully under his probings. He took his other hand away from Sarah and reached out to stroke Britney's titties, feeling the nipples stiffen under his touch. Sarah was busy masturbating her brother, licking her lips as she did so.
"Suck my dick Sarah," urged Billy, seeing the look of hunger in his young sister's big, emerald-green eyes. She smiled and bent down into her brother's lap, sucking on the purple head of Billy's cock, swirling her wet tongue over the head whilst her fist still pumped the base of that fine youthful tool.
"Oh Billy, that's good," Britney was sighing as her brother finger-fucked her bald cunt whilst pinching her nipples in turn, tugging those strawberry-red nips out a little and releasing them and watching them spring back into position on those budding young breasts adorning his sister's chest. He leaned in and kissed Britney, a passionate snog, their tongues intwining. Billy slid a third finger up into Britney's cunt, and all the while Sarah's head was bobbing in Billy's lap as she sucked his cock with considerable skill for a twelve year old.
After a few minutes of such foreplay, Sarah took Billy's dick out her mouth.
"I wanna fuck," she said, "Sit back Billy, I'll get on top."
Billy took his fingers from Britney's pussy and leaned back on the sofa, watching as Sarah knelt astride his lap. He held his prick upright and rubbed the saliva-slick head against Sarah's wet pussy lips which hovered just over it. Sarah began to lower herself, her cunt slowly swallowing up her brother's prick. She went down and down until every inch of Billy's dick was in her cunt.
"Mmm, that's so good," she panted.
"Ride me Sarah," Billy said, "Bounce on my dick you beautiful little slut."
Sarah grinned and kissed her brother, then placed her hands on his shoulders. She raised herself up so that half of Billy's cock emerged from her hairless young twat, then she lowered herself. She repeated this, a look of pleasure on her pretty face, Billy stroking the girl's tits.
Britney watched from beside the pair for a few minutes, then she got up. She knelt on the floor in front of the sofa, in between Billy's lower legs with her twin sister's ass - rising and falling as she bounced on Billy's dick - right before her.
"Reach round and spread her cheeks," she said to her brother.
Billy did so, reaching round to clap his hands to Sarah's buttocks. He parted them and Sarah's hairless little asshole, just above her cock-impaled cunt, came into Britney's view. Britney sucked on a forefinger then reached out, tentatively placing the tip to her sister's anus. Sarah stopped riding Billy's cock and held still, Britney taking this opportunity to quickly drive her finger up to the knuckle into Sarah's shitter.
"Oooh, that's nice," Sarah gasped, "Yeah! Finger my asshole Britney, whilst Billy's cock fucks my pussy." She began to rise and fall again, riding Billy's hard cock which slid to and fro in her tight wet cunt-channel. Britney remained kneeling and fingering Sarah's asshole. She slid her digit back and forth slowly at first, then went more vigerously. Sarah enjoyed this a great deal, and she rode Billy's cock harder. Britney then rammed her finger up to the knuckle into Sarah's rectum and held it there, wriggling the digit around in Sarah's guts and making the girl cry out with pleasure.
"That's so good," she wailed, "Mmmm...my brother's big dong up my pussy and my sister's in my bum. Mmmmm."
"Do you think you could handle a cock in your bum?" asked Billy.
Sarah stopped riding her brother for a moment.
"Hmmm," she pondered, "There's an idea."
"Go for it," Britney sniggered, sliding her finger out of her twin's asshole and idly sucking on it, "I think you could take it. If a finger feels nice up the bum, a cock would feel even nicer. I'm gonna try it."
"Okay, let's go for it," concluded Billy.
"Yeah," Sarah agreed, "Some bum-fun! Excellent!" She giggled like a child and raised herself one last time, Billy's prick popping out of her pussy and slapping erectly to his lower belly. Sarah got off the sofa and Billy did likewise, ready to direct things.
"Sarah," he began, "Get onto your hands and knees on the floor. Britney and me will lick your asshole, get it nice and wet."
Sarah followed these instructions, in a very prone position on all fours in front of the fireplace with her cute pale bum thrust out and spread, her bald little ass-pucker winking hungrily for attention. Her brother and sister got behind her.
"You first," Billy said to Britney, like a true gentleman.
"Thanks," smirked Britney, and she dived on in, running her tongue up and down the cleft of Sarah's ass. She slobbered on her sister's asshole, her tongue probing into that orifice, finding it a little loose from the earlier fingering. She slid her tongue right up into Sarah's rectum and slurped away, her hands clapped to her sister's buttocks.
"Oooh, that's so nice," Sarah was gasping, "I love having my bottom licked. Mmmm."
Britney spent a moment or two eating out her twin sister's ass then raised her head and moved aside. Billy followed his little sister's example and spread Sarah's ass with his hands and leaned in. He ran his tongue in circles over Sarah's shit-hole then slid it in, up into her rectal passage. After a minute he knelt up, his cock raging hard.
"Time to deflower your ass sis," he said, gripping the base of his erection and nudging Sarah's well-licked anus with his prick-head.
"Go for it," Sarah urged him, "Go gently though."
"I will honey."
"Then you can fuck my ass," Britney smirked, kneeling nearby, casually fingering her cunt.
Billy began pushing his cock into Sarah's asshole, going slowly but firmly, Sarah's sphincter soon blooming open and allowing Billy's cockhead in.
"Uuuh, that's good," she cried, "Work it right up me brother, mmmm! I like that!"
Billy eased forwards, making good progress, watching his cock dissapear up his little sister's tight bum. Soon, the fifteen year old's dick was lodged in Sarah's rectum to the hilt.
"What a tight ass," he gasped, "Oh my, it's even tighter than your cunt. Mmmm!"
"That's so good," Sarah grunted, "Oh wow, oh yeah! You gotta try this after me Britney!"
"I will," her sister assured her.
Billy eased halfway out of Sarah's asshole then fucked back into her, Sarah crying out with pleasure. Billy began working up a rythm, gripping Sarah's slender hips and working his cock back and forth in the girl's clutching anus. He buggered his sister lustfully, pumping that tight ass with his hard prick. Britney had two fingers up her twat now and had also popped a finger from her other hand up her ass. She knelt and fingered both her holes as she watched her brother fuck her sister's ass. She couldn't wait for her turn.
"God this is so good, so fucking tight," Billy was panting, humping Sarah's ass faster now. The girl bent over before him was in ecstasy, waililng with joy as her tender bottom was ravished by her big brother's thrusting erection.
"Hold your cum back Billy," Britney said to the youth, "I want you still hard to fuck my ass next!"
"Okay honey, just gimme a minute."
Billy thrust deeply into Sarah's shitter for a moment longer then withdrew from her, his cock soiled brown as it emerged from Sarah's tender ass. Her sphincter was wet with saliva and hung open from it's hard fucking.
Britney got onto her hands and knees after Sarah had moved aside. Billy licked Britney's asshole, licking it well, sliding his tongue into her rectum a few times. He then sat back whilst Sarah had her turn, the girl licking her sister's shitter thoroughly. Billy reached behind Sarah and pushed a couple of fingers up her bottom whilst jacking off his hard dick with the other hand and watching as Sarah pushed her tongue in and out of Britney's ass.
All was prepared. Sarah moved aside and watched as Billy shuffled up behind Britney. He followed the same plan as he had with Sarah. He pushed his cock to Britney's asshole and applied pressure until the anus opened up to let him partially enter her.
"That's so good, oh yeah," Britney gasped, "Go on Billy, cram it right up my ass."
Billy held Britney's hips and rammed forward, mercilessly slamming his pole right up Britney's rectum.
"You like that?" he grinned.
"Yeah, yeah," panted Britney, the girl's nude body shaking with pleasure, "Oh my God I feel so penetrated, so full of cock! Yeah, mmm. Fuck my ass Billy, fuck me up the bum good 'n hard!"
Billy did so, working his cock up and down in Britney's asshole, in heaven at the tight wet grip of his sister's rectal passage. Sarah reached under Britney and frigged her clit, adding to Britney's pleasure. Billy sodomized Britney deeply, loving the intimate heat of her bottom. Her anus gripped his shaft tightly and he felt his orgasm rising. He put it off for a while, slowing his pace and just steadily fucking Britney's shitter. But it couldn't be put off forever.
"I'm gonna cum," he grunted, thrusting harder and faster, "Here it is..uuuh...fuck!"
"I'm cumming too!" Britney announced, "Uuuuuh! GOD YEAH!"
Billy rammed his cock one last time into Britney's rectum and unleahsed his pent-up sperm, blasting his hot load deep into Britney's guts.
"UUUUH, FUCK!" he cried, his cock pumping madly in the grip of his little sister's anus. Britney shook with ecstasy.
Sarah meanwhile worked two fingers up her own cunt and two into her sister's, Britney enduring a long and wild climax as Sarah fingered her cunt and her brother's cock pumped hot fuck-sauce up into her rectum. Billy's sperm seemed never ending and he hunched over his sister as he gave her a sticky enema of his boy-cum.
Billy spurted out the last of his spunk and hung in Britney's ass for a moment. Then he pulled out, breathing deeply, and knelt back on the floor. Britney fell forward with cum leaking out her ravished asshole. Sarah bent down and kissed her sister's buttocks then shuffled over to Billy and kissed him hotly on the mouth.
"That was delightful," Britney said, turning over and lightly fingering her cunt and asshole, "Mmmm! I've been fucked in all my holes now! It's so much fun having sex!"
"Let's have more," Billy said, taking his lips from Sarah's, "My cock is getting hard again already, just thinking about fucking you dear girls."
"It's almost fully stiff," Sarah said, gripping her brother's cock and stroking it.
"I know what'll get me fully stiff," Billy said, "A bit of corporal punishment! I think you two children need a bit of a spanking for being such naughty sluts."
"Me first," Sarah said, standing up. Like Britney and Billy, her nude body was glistening with sweat.
"Okay," Billy said, and he stood up also. He went to the sofa, sat down and patted his thighs. "Come and bend over my lap Sarah, I'll smack that pretty behind and then I'll fuck it."
Sarah scampered over and got into position, bent over her brother's lap, hands flat on the floor in a very vulnerable position with her bottom sticking up. It was perfect for Billy, Sarah's lower abdomen and cunt laying over his thighs, her cute round bottom right before him in his lap. He placed one hand on his sister's lower back and placed the palm of his other hand across the girl's buttocks.
"Do it," Britney urged her brother as she stood up, eager to watch.
Billy raised his arm and bought it down with a SMACK, Sarah's pre-teen body shaking with the force of the spank.
"Smack me again," she begged, "Smack my bottom red, then fuck it!"
Billy did so, raising his arm and whacking the girl's ass. Then again, and again. Sarah was yelping with pleasure as her buttocks were smacked red, her toes - just hovering an inch from the carpet - flexing and clenching, her legs trembling. After twenty smacks, Billy stopped. Sarah clambered off her brother's lap.
"That was fantastic," she said, "It just makes my bum-hole itch for another fucking even more." She got on the floor on her hands and knees, her ass thrust out towards her brother, her anus winking out at him. "Come and fuck my ass Billy, ram that big cock up my pooh-hole. I need it! Pleeeease come and fuck me up the bum!"
Billy could not refuse. His cock was like a solid wooden club that bobbed in the air as he got down behind Sarah. Her asshole was yawning open a little, still loose from it's previous fucking.
"Here I come sis," Billy said, and pushed his cock-head into Sarah's anus.
"Ram it right up me," she begged, "Right in to the hilt!"
Billy reached forward and held Sarah's delicate shoulders and rammed forward, sheathing his cock in the girl's bowels.
"Uuuuh! Aaaah, that's good Billy, I can feel you in my bum! AAAH! Shaft my bottom, hard, hard!"
Billy slid most of his cock out of Sarah's ass then slammed it back in. Britney knelt nearby and reached under Sarah to frig her pussy.
"What a hot ass," Billy was panting as he fucked Sarah's shitter deeply and hard, "Oh yeah, what an ass. I'll not cum though, I'll be spanking you next Britney."
"Goody," the girl grinned whilst still masturbating Sarah.
"I'll smack your bottom just as hard as I did Sarah's..."
"Harder!" interrupted Britney.
"Okay, harder," grinned Billy, "I'll smack it raw then I'll FUCK you up the ass like I'm fucking Sarah up the ass right now."
"Look at it Britney," panted Sarah over her shoulder, "look at my bum! See Billy's dick in it? Is he slamming in to the hilt?"
"He is," confirmed her sister.
"Right in to the root?"
"He is, don't worry Sarah. Billy's cock is slamming right in to the root. It's beautiful! It's so beautiful to see your lovely bottom being so thoroughly fucked by Billy's dick!"
"Uuuuh, aah," Sarah gasped, "Oh fuck I'm cumming! Fuck my bum Billy! Finger my pussy Sarah! UUUUH!"
She climaxed, hard, Billy not relenting in his thorough buggering of his little sister. Britney fingered the girl's twat throughout it. Finally Billy stopped, tired out. He slipped his pole out of Sarah's behind and let her slump forward, exhausted and sweaty.
"My turn for a smacking!" Britney said, leaping to her feet.
"It sure is you naughty little minx," Billy said, also standing up. He went to the sofa and sat down, Britney eagerly laying across her brother's lap, her bum in the air ready for a smacking.
"I've been very naughty," Britney giggled over her shoulder, enjoying this little game, "Shall I tell you how naughty I've been?"
"Yes, tell me, and I'll give you the smacking you deserve, my mischievous little sister."
"Well, I've been masturbating myself for some time now," Britney admitted.
SMACK! Billy's hand clapped hard to tender white cheeks, making them quiver.
"I've been masturbating with my twin sister."
SMACK!
"My sister and me masturbate each other..."
SMACK!
"...and put our fingers up each others bottoms."
SMACK!
"Sarah and me jerked off our big brother and then had him frig us."
SMACK!
"We sucked his cock and swallowed, and Sarah and me have also licked out each other's pussies."
SMACK!
"Me and my sister had our big brother deflower our pussies..."
SMACK! SMACK!
"...and bums..."
SMACK! SMACK! SMACK!
"...and we have every intention of getting our dear brother to fuck our pussies and assholes a lot more! And we want to suck his cock more and drink his cum and do all sorts of wild stuff, like having him spunk on our faces or up our bums, then Sarah and me will suck the sperm out of each other's bums and..."
SMACK! SMACK! SMACK! SMACK! SMACK!
"Yeeowch!"
SMACK!
"And last of all," grinned Britney, the naked girl sweaty and shivering with pleasure from her smacking, "me and my sister have been letting our brother spank our bottoms in kinky corporal-punishment games." Billy laughed, gave Britney one more smack on her glowing red ass-cheeks then let her get off. Sarah had been watching this whilst sitting in an armchair and fingered her cunt as she watched Britney now get on all fours on the carpet.
"I take it you want ass-fucking now?" Billy said, getting up, his prick raging hard.
"Absolutely, come and fuck my bum," Britney urged him. Billy got behind the girl and slid his erection elegantly into Britney's ass. Fully lodged in her rectum he held his sister's hips and shafted her shitter deeply.
"Fuck me, fuck my ass," Britney was urging him, "Ooooooh, that's so good, it's so nice! UUUUH!"
"Yeah, yeah, take my cock in your shitter," Billy grunted, "What a tight ass!"
"Harder, faster! Yeah! UUUUH!"
Billy ass-fucked Britney for five-minutes, but before he came he began to slow down.
"I came up your butt last time Britney," he announced as he slowly withdrew his cock from her bowels, "I'll cum up yours now Sarah."
Sarah got off the armchair, all excited. Britney moved aside and lay down, exhausted, as Sarah retook her position on all fours. Billy pushed his cock deep into Sarah's rectum and began sodomizing her hard. Sarah panted with ecstasy and banged her butt back onto her brother's invading pole.
"I'm cumming now," he gasped, "Oh fuck yeah, yeah! UUUH!"
He shafted Sarah's anus throughout his climax, wild with lust as he spurted hot sperm deep into the girl's shit-chute.
"Cum right up me, right up my bum," wailed Sarah, feeling the sperm flood her rectum, "MMMM! Oh yeah, that's gooood!"
"UUUUH!" grunted Billy, fucking his cock one last time into Sarah's shitter and firing out the last of his spunk. He hung in Sarah's ass for a moment, out of breath, before he finally slid out of her. They joined Britney in sprawling across the floor, tired out.

They eventually had a bath together, dressed and had lunch. Things seemed fairly innocent for a time, but not for long! At two o'clock they all went to Billy's room for more fun. Billy fucked each girl's twat - first Sarah's, then Britney's. He fucked Sarah vaginally once again and shot his load up into her womb. Sucking and fondling soon had Billy erect once again. They indulged in some sixty-nines for a while in various combinations - Billy and Sarah, Britney and Sarah then Billy and Britney. Then the twins had a sixty-nine again, Britney below and Sarah on top. Billy slid his pole up Sarah's bum and buggered her whilst she and her sister slurped at each other's cunts. Billy shafted Sarah's shit-chute deep and hard before unleashing his sperm deep into the girl's belly.
They had a rest for a while, simply talking and stroking each other's bodies. With their father due home soon they had one more romp on the bed, Billy fucking Sarah and Britney in each girl's cunt, ass and mouth - five-minutes for each hole - before he chose to fire his sperm over Britney's barely-budding titties. He splashed his cum all over them and watched as Sarah leaned in and licked them clean.
The siblings were washed, dressed and looking thoroughly innocent by the time their dad arrived home. When their dad was in bed, the girls sneaked into Billy's room and he quietly fucked his sisters for half-an-hour before blowing his nuts up Sarah's tight twat. Then the girls returned to their beds.

Wednesday

Billy, Britney and Sarah had breakfast with their dad that morning, and as soon as Mike left for work the siblings were rushing upstairs. They stripped in Billy's room and fucked all morning. Billy was insatiable, as were the girls. He shot three loads of cum in a row - the first down Britney's thirsty throat, the second in Sarah's cunt and the third up Britney's bum.
They had lunch and relaxed until four o'clock, when Billy fucked each girl in the living room. He came up each girl's cunt and they'd cleaned up and dressed by the time their dad arrived home.
Mike stayed up late to watch a movie on TV that night and by the time he'd gone to bed after midnight, Billy had fallen asleep in his bed and the girls had fallen asleep in theirs. Missing out on a nocturnal fuck didn't bother the kids though, they knew they'd have tomorrow morning to have some fun!

Thursday

"Wakey wakey," Sarah said as she opened Billy's bedroom door and strolled in. She was fresh out the shower, her long blonde hair tied up in pig-tails with elaborate pink ribbons. She was otherwise stark naked.
"Uh?" muttered Billy, sitting up and rubbing his eyes.
"Dad's gone to work," Sarah explained as she hopped onto her brother's bed, "You've slept in a bit later than usual, it's gone nine-thirty."
"Cool, I'm horny. I was dreaming about you and Britney."
Sarah tugged the duvet down, exposing Billy's groin. The fifteen year old's cock was as stiff as an iron-rod, laying erectly across his belly.
"Obviously a very nice dream," she giggled, bending down and kissing her brother's dick gently.
"Your hair looks nice in pig-tails," Billy said.
"Thanks. It gives me a bit of a 'lolita' look don't ya think?"
"Yeah, but given that you're only twelve, I don't think you need pig-tails to get the 'lolita' look! You do look nice in them though."
Sarah kissed her brother on the lips.
"Where's Britney?" Billy asked.
"She's just drying off from her shower. We had one together."
"I take it you did more than just soap each other down."
"Naturally! We frigged each other a bit, fingering each other's pussies and assholes, getting ourselves all hot and ready for you! We've been discussing ideas too for more fun. I think that, as you fulfilled your fantasy of spanking Britney and me, us girlies should have a little fantasy fulfilled."
"And what request would this be?"
"You'll see. I think I hear Britney now."
Sure enough, Britney - her damp hair cascading loose down her back - strolled into Billy's room. She was naked, her body fresh and clean. Both girls carried the sweet aroma of their favorite apple-scented shampoo.
"Morning Billy," she smiled.
"Morning sis."
"I was telling Billy about our plan," Sarah said to her twin.
"What request is this you girls have been concocting?"Billy asked.
"We want to pee on you," Sarah sniggered.
"Huh?" Billy frowned.
"Come on, it'll be fun," Britney insisted, "I heard someone talking about it at school once. It's called 'watersports' or something. Wanna try it?"
"Okay," shrugged Billy, "I'm up for anything. And it is only fair as seen as you let me smack you."
"Though we enjoy spanking as much as you do," Britney pointed out, "Especially when you fucked us up the bum straight after smacking us the other day, that was nice. Anyway, back to the present! I need a pee."
"Let's go to the bathroom," Sarah said, "We don't wanna make a mess. You can lie in the bath and Britney and me will wee all over your naked body."
"I think I'll enjoy this," Billy smiled. He got out of bed and, followed by his horny little sisters, he went to the bathroom.
Billy got into the big (empty) bathtub and lay down, his cock erect.
"Me first, I'm burstin'," Sarah said. She got into the bathtub and placed her feet on the white porcelein either side of Billy's hips. She lowered herself, her hands reaching out to grip the end of the bath, her pussy hovering just over Billy's erect dick. Her bladder was fit to burst and as soon as she relaxed it her piss began to flow.
"Whoa," gasped Billy, a little taken aback by the strenght of the jet of piss splattering over his naked body. The golden fluid streamed out, all over his chest and torso.
"Is that nice?" giggled Sarah as she pissed over her brother.
"Yeah, nice and warm," smirked Billy, "This is a turn on! Yeah, my dick's feeling even harder now! Aim some at my dick sis."
Sarah shuffled back a little, still pissing, aiming the stream downwards now at her brother's pole. Billy's cock twitched erectly as it was hit by a warm flow of piss. Finally the stream ended. Sarah's cunt dripped a few more drops of urine onto her brother's dick and she stood up.
"Nice," she smiled, "Your turn Britney."
Sarah got out the bathtub and her position was taken by Britney. She squatted down and, grinning like a naughty girl, she began urinating over her brother. The boy was loving this, feeling the lovely warm stream of his little sister's piss splashing over him.
"Shower me in it," he panted, "Mmmm! All over me!"
Britney emptied her bladder over the youth then got up and out the bath. Billy stood, piss dripping down him as he got out of the bathtub.
"I need a piss now," he said, "I don't suppose..."
"Of course you can piss on us!" Sarah said, pre-empting her brother's question, "Come on Britney."
The twins got into the bathtub and knelt up alongside each other, shoulder-to-shoulder, their hands on the rim, looking up as Billy stood in front of them at the edge of the bath. Despite his erection he was ready to piss, his bladder feeling full. He held his cock and aimed it right at Britney's face.
"Here it is girls," he announced, and began to urinate. The stream his Britney right in her face. After a few seconds Billy moved his dick to oneside and began pissing all over Sarah. The girl bravely opened her mouth and caught some of the urine, swallowing it down and grinning.
"Try swallowing it," she said to Britney as their brother moved again to piss in Britney's face. The girl opened wide and caught some piss, swallowing it and smiling. Billy was coming to the end and stepped forward a little and jammed his cock into Sarah's mouth, the girl guzzling down the final jets of piss. It tasted warm and sour but she didn't care, she felt so horny. The flow ended and Billy stepped back, masturbating a cock that was fully hard and ready to fire out something other than piss!
"I'm so turned on!" he said, "I'm about to blow any second, I don't think I'll last long enough to stick my dick up any of your holes."
"Then shoot your load over us," panted Britney, drenched in piss, as was her sister, "Give us a facial."
Billy stepped forward again and jacked off his cock, pumping it in his fist, his cock-head thrust right into Sarah's face.
"Here it is...uuuuh! FUCK!"
His sperm exploded out, a thick stream of sticky cum that splattered over Sarah's pretty face. A second squirt went into her willing mouth and she swollowed. Still masturbating hard, Billy aimed his cock at Britney and spurted semen over her face. Britney caught the next two pumps in her mouth and she swallowed it down. Billy then fired the final squirt of semen into Sarah's face then jammed his dick in her mouth, the girl sucking out the last of the spunk. Britney leaned in and sucked on Billy's balls.
Eventually the girls took their mouths away from their brother's dong.
"I trust you'll be hard again soon," Sarah grinned, "We need fucking!"
"I'll be very stiff soon," Billy said.
"Oh look at me," Britney giggled, standing up, "I just had a shower and now I'm all covered in piss and sperm!" She laughed and hopped out the bath, embracing her piss-slathered brother and kissing him. Sarah did likewise.
Britney got to her knees and licked and sucked her brother's cock, Sarah remaining standing, on her tip-toes to reach up and stick her tongue down her brother's throat. Billy snogged his little sister hotly whilst his other sister gave him a great blow-job. It didn't take long for his cock to stiffen, rock hard between Britney's slurping lips.
"Let's fuck right here in the bathroom," Britney said as she took her brother's erection out her mouth and stood up.
"Okay," Billy said, taking his mouth from Sarah's, "Who's first?"
"Me," Sarah said, "I'm so hot and horny, I'll burst into flames if I'm not fucked in the next ten-seconds!"
She giggled and got onto her hands and knees on the furry bathroom rug on the floor. Billy got behind the girl and pushed his hard pole up into her hot pussy.
"Oh yeah, nothing like fucking a tight pussy in the morning," he grinned as he began to shaft the girl doggie-style.
"Mmmm, I needed that," Sarah panted. Britney - who, like Sarah, was dripping with urine and had a face splattered with jism - sat in front of her sister. She spread her legs and Sarah dived in, licking thirstily at Britney's piss-dripping cunt. She ate her out well, Britney's face a picture of ecstasy. Billy had a good view of this sister-on-sister oral session as he banged Sarah up the cunt.
"Lick your sister out," Billy grunted to Sarah, "Eat out that pussy!"
He shafted Sarah's twat deeply, Sarah moaning with pleasure into Britney's wet cunt.
"I'm cumming," Britney wailed, "UUUUH! Lick me out Sarah, lick my cunt. MMMM!"
She held Sarah's head in her hands and pushed her sister's face into her pussy, her legs quivering with ecstasy.
"Lick her out Sarah," said Billy, fucking the girl's cunt harder. Sarah slurped at Britney's pussy, drinking in her sweet juice. Her climax subsiding, Britney let out a long sigh of pleasure, Sarah raising her piss, cunt-juice and semen splattered face and kissing her sister hotly. Billy was on the brink of orgasm so he slowed down then slid his cock out of Sarah's clutching pussy. He watched as the girls switched places. Britney got on all fours before him, her ass in the air, Sarah sitting in front of her sister and spreading her legs.
"Fuck your dick up me," Britney ordered her brother. Billy did so, pushing his pole up her tight wet pussy. Britney then started eating out her sister, licking Sarah's cunt thoroughly. Sarah panted with delight, her eyes fluttering as her cunt was tongued. Billy shafted Britney for a good ten-minutes, holding back his orgasm. Eventually it rose up though.
"I'm cumming," he wailed, shafting harder, "Up your pussy sis...yeah! AAAH!"
His cock exploded thick semen deep in Britney's womb, the girl receiving her brother's cum in her cunt as she licked Sarah's twat deeply. Sarah was cumming too, grinding her cunt into her twin's slurping mouth as she climaxed.
"Lick me, lick me Britney, yeah! Oh, oh, I'm cumming!"
Billy slammed his cock repeatedly into Britney's cunt and flooded her with his fuck-sauce. By the time he slid his wilting dick out of Britney, letting the girl get up, they were all exhausted. They were very messy too so they had a nice long soak in the bath and scrubbed each other down. Then they dressed and went downstairs for breakfast.

It was early afternoon. Billy had finished cleaning up after lunch and, wearing just a pair of shorts, he strolled into the living room. Sarah and Britney were sitting on the sofa, watching TV, both in just their white cotton panties and trainer bras. It didn't seem worth getting fully dressed!
"Feeling horny?" Sarah casually asked Billy as the boy sat in between them on the sofa.
"I sure am," he smirked.
"Me too," Sarah said.
"And me," added Britney, "I need a spanking I think. A nice spanking on my bottom, then a good, hard bum-fucking!"
"Why don't we spank each other?" suggested Sarah to her sister.
"Yeah, that'll be fun," Billy interjected, "I'll watch you smack each other's bums."
"Okay," agreed Britney, "Come on Sarah."
The sisters got up and walked into the center of the room, Billy meanwhile slipping off his shorts and sitting naked, stroking his stiffening prick.
"You smack me first," Britney giggled to Sarah. She turned round and bent over, hands on her knees, her bottom thrust out.
"Get ready for a good whacking," sniggered Sarah, hooking her thumbs into the elasticated waist of her twin's panties. She tugged them down, letting them fall to Britney's ankles so that her bum was bared and ready.
"Go for it Sarah," Billy said, jerking off his erection, "Give Britney a good smacking then I'll step in and fuck her ass."
Sarah licked her lips as she stood slightly to oneside of Britney. She raised her arm and swiftly bought her palm down onto Britney's bum-cheeks.
"Yeeow," Britney giggled, "Nice! Do it again!"
Sarah did so, smacking her sister's bottom a bit harder. She kept it up, standing there in just her panties and bra as she smacked her sister's bare bum. Billy was in heaven as he watched this kinky little scene, stroking his pole as Britney yelped with a mixture of pleasure/pain as her bottom was whacked. Sarah was getting into it now, enjoying smacking her sister's cute little ass. However, her arm was aching after twelve smacks. She took a quick breather.
"Come on, smack me more," Britney begged, "I want my ass to sting, then I want Billy to bugger me."
"Okay, here come some more," Sarah said, and she resumed spanking Britney's butt. After two-dozen smacks she stopped. Britney kicked her panties aside so that she wore just her little bra as she got on her hands and knees on the floor. Billy scooted over and licked Britney's ass, swirling his tongue around that puckered pink orifice between the girl's reddened cheeks.
"That should be enough lube," Britney said after a moment, "Shove your dick up me Billy, up my bum!"
Billy knelt up and pushed his cock into Britney's ass. The girl let out a long moan of pleasure as her ass swallowed up her brother's pole, Billy soon wedged to the hilt in the girl's ass.
"Uuuh, I love fucking your ass sis," he panted as he sodomized the girl deep and hard.
"I want spanking next," Sarah said, standing nearby. She watched as Billy fucked Britney up the shitter for a good few minutes, then Sarah got down and reached under her sister to frig her pussy. This delighted Britney even more and she shortly had a noisy and powerful climax as her cunt was fingered and her asshole fucked hard. Billy withdrew from the girl's anus and he sat back on the sofa, jerking off slowly.
"Time for vengance," laughed Britney as she got to her feet and turned to Sarah, "Bend over!"
Sarah did so, hands on her knees, butt thrust out. Britney pulled down Sarah's panties then smacked her, thirty hard whacks to Sarah's bum-cheeks so that they glowed red. Then Sarah got on her hands and knees and, after licking the girl's anus, Billy slid his cock up her butt. Britney frigged her sister's cunt in the meantime.
"Yeah, yeah, fuck my ass," Sarah panted, "That's so good, it's just so good being buggered after a spanking! Mmm! AAAH!"
"Uuuh, I'll be cumming soon," Billy grunted, holding Sarah's delicate waist as he roughly rammed his prick repeatedly up the pre-teen slut's rectum. He fucked harder and faster, Sarah hitting a powerful climax.
"I'm cumming, I'm cumming," she cried, "Oh God! God! Fuck my butt Billy!"
"I'm cumming too," announced her brother, "Fuck, fuck...oh yeeeeah!" He rammed his pole to the hilt in Sarah's fudge-tunnel and pumped out his sperm. Britney masturbated her sister throughout this, Sarah's orgasm prolonged as she felt her intestines fill with bubbling hot sperm. Billy emptied his nuts up his sister's crapper before finally withdrawing. Both girls hugged each other and then their brother.
Afternoons were far less boring than they had been on previous summer vacations!

Before their father got home late that afternoon, the trio of siblings fucked in Billy's bed. The boy was feeling energetic, having had a brief nap earlier. He fucked Sarah's cunt in the missionary position, then gave Britney the same treatment. Then he licked out each girl's cunt and bought them both off to orgasm before the girls returned the favor by spending a good while slurping on Billy's cock, worshipping it with their tongues and lips. Billy then fucked Britney up the ass for a few minutes before he withdrew and got astride Sarah, masturbating into her pretty face. He coated her in cum and watched as Britney licked her sister's face clean, both kissing and swapping cum. Billy got another hard-on immediately and had the girls bend over, side-by-side with their cute bottoms in the air. Billy fucked his sister's tight assholes, spending a few minutes in each ass before swapping to the other girl, and then back again. For almost an hour Billy sodomized the lusty pre-teen twins, going back and forth between each girl's butt. It was Britney who had the honor of finally receiving her brother's injection of semen into her rectum.
They had a bath and, as usual, were clean and dressed when their unsuspecting father arrived home.
When their dad had gone to bed, Billy sneaked into his sister's room. They were all fairly tired so the girls just sat on the edge of the bed and frigged their own pussies whilst Billy stood in front of them and jacked off his cock. When their brother reached his orgasm, the girls put their heads together, opening their mouths as Billy stepped forward and sprayed his sperm all over them. He sneaked back to bed, leaving his sister's to giggle and lick each other's spermy faces clean before they finally settled down to sleep.

Friday

The three of them were sitting naked on Billy's bed. Their father had just left for the day and the siblings were about to have a nice pre-breakfast fuck.
Britney was leaning over and kissing Sarah, the girls sliding their tongues into each other's mouths. They stroked their titties as they kissed, Billy watching the twins snog whilst stroking his hard cock.
Britney then took her lips from Sarah's and she leaned over and kissed Billy. She pushed her tongue into his throat and they frenched lustily. Sarah busied herself bending down and taking Billy's hard cock into her warm wet mouth. She sucked deeply on the boy's dick, bobbing her head. Both girls were wearing their hair in pig-tails again as their brother seemend to get a kick out of the emphasis on the schoolgirl-look!
Shortly, Billy moved back from Britney.
"I wanna fuck your tight pussy," he told her.
"Goody," grinned Britney. She lay on her back, spreading her legs. Sarah took Billy's cock out of her mouth to allow the boy to mount Britney.
"Here it is honey," Billy said, easing his pole into Britney's cunt.
"Mmmm, yeah," purred the girl, "Yeah, that's nice!" She wrapped her arms round her brother and they kissed, Billy slowly fucking his prick to and fro in the girl's tight pussy. He shafted her at a fairly slow pace, Sarah kneeling next to them and fingering her pussy.
After ten-minutes the girls switched over. Britney know knelt up and frigged her cunt whilst Sarah lay back, Billy on top of her and humping her twat. He picked up some pace shortly and fucked Sarah harder.
"I'm cumming," the girl wailed, "Uuuuh, fuck me Billy!"
Billy screwed Sarah through a powerful climax but the teenage kept his own orgasm held back. His dick was sticking straight up, very erect and throbbing, when he dismounted Sarah. Britney leaned over and spent a moment sucking her brother's dick.
"Do you want another good fucking Britney?" asked Billy.
"What do you think?" grinned the girl, taking her brother's dong out her mouth. She turned round and got on her hands and knees, ass raised high. Billy shuffled up behind the girl and pushed his rigid dick up the girl's ass. Britney gripped the pillow as she was anally penetrated. Like her sister, Britney was quickly getting used to taking her brother's dick in her ass, and also like Sarah she thoroughly enjoyed it.
"Yeah, right up there with no lube," Billy commented, wedging his cock fully in Britney's shit-canal.
"Fuck my ass Billy, fuck it good and deep!" Britney panted.
"You got it sis."
Billy began fucking Britney's shitter steadily, sliding his cock up and down in her rectal passage. It was lovely and tight up there, his sister's sphincter taut round the base of his shaft.
Sarah stood up on the bed and stood by the side of Billy.
"Lick my pussy brother," she said.
Billy was more than happy to comply. He turned his head and buried his tongue up into Sarah's pussy, slithering it up into her wet twat. Sarah gasped with pleasure, rubbing her nipples as her brother sucked her cunt, Billy all the while ramming his cock deep into Britney's rectum.
"That's so good, I love being bum-fucked," Britney panted, "Oh yeah, yeah, Billy! Mmmm! Screw my ass hard!"
Billy increased his pace a little, thrusting faster into his sister's behind. He was still licking Sarah's cunt as he ass-fucked Britney.
After a few moments, Britney climaxed, wracked with pleasure as she reached down and fingered her pussy whilst her brother's cock slammed into her ass. Once Britney had finished cumming, Billy took his mouth from Sarah's dripping twat and slowly slid his pole out of Britney's shitter.
"My turn for a good fucking," Sarah said, "Move over sis."
Britney rolled to oneside and Sarah got on her hands and knees, ass spread for Billy.
"Which hole do you want shafting?" Billy asked, stroking his hard cock.
"My pooh-hole," sniggered Sarah.
"Here goes then," Billy said, and he gently squeezed his cock-head into Sarah's tight little anus. The girl tensed, quivering with pleasure. Billy thrust his cock halfway in, paused for breath, then shoved the rest in before he gripped Sarah's waist and began sodomizing her. Sarah grunted with pleasure into the pillow, ripples of pleasure shooting up her young naked body as her brother ass-fucked her.
Billy buggered Sarah for five-minutes before he slid his dick out of her ass.
"I'm about to cum," he announced, "I fancy shooting some spunk over you girls. Any requests as to where you want me to cum?"
"Over my belly," Sarah said, flipping over and laying on her back. She spread her legs and Billy knelt between his sister's parted thighs. He began jacking off his cock, pointing it down towards Sarah's flat stomach.
"Here, I'll do that," Britney said. She reached out and took Billy's cock into her fist. She masturbated her brother with great skill, stroking his foreskin back and forth in a tight grip, keeping the tool angled down at all times. Sarah looked down and licked her lips, anticpating the sperm-shower.
"Uuuuh, I'm cumming, fuck!" gasped Billy, "Oh yeah!"
His cock began shooting out thick wads of sperm over Sarah. Britney pumped the cock in her fist throughout the climax, ensuring the flow cascaded all over Sarah's stomach.
"Oh wow, what a cum," gasped Billy, his cock spurting out one last wad of semen over his sister. Britney let go of Billy's cock and the boy leaned back, out of breath. Sarah's belly was smeared in semen.
"Aah, some nice sperm for my breakfast," grinned Britney, and she leaned in and started licking her sister clean. Sarah giggled, slightly ticklish from the feeling of her sister's tongue lapping up the semen on her belly. Britney swallowed the sperm she licked up but was kind enough to gather some in her mouth to lean over Sarah.
"Do it, spit it in my mouth," Sarah said, and she opened her mouth wide.
Britney pursed her lips and a bubbly mixture of saliva and cum welled up and dangled from her lips. It dropped into Sarah's mouth, onto her tongue. The girls then kissed and Billy leaned forwards to stick a couple of fingers into each girl's cunt as the pair of girls snogged each other.
"What a pair of horny little sisters I've got," the boy smiled. Britney took her lips from Sarah's and sat up to kiss her brother. They frenched each other, Sarah then taking her turn in snogging Billy.
"Your hard again," Britney said, stroking her brother's fresh erection, "How about another fuck before breakfast?"
"Okay girls," Billy said, "Right then, Britney, why don't you lay down and Sarah can get on top of you in a sixty-nine? Then I'll give Sarah some more anal penetration whilst you lick each other's twats."
"Sounds good," smiled Britney. She lay on her back, legs spread. Sarah mounted her twin, inverted, lowering her head between Britney's legs. Britney had Sarah's cunt above her and she began to lap greedily at it like a thirsty dog, slurping at those tight wet lips. At the other end of the compact pair, Sarah was sliding her tongue into Britney's cunt. Billy got behind Sarah's spread ass and leaned down to lick it. He ran his tongue over the girl's anus which was hanging open a little. He pushed his tongue into her warm, wet, glistening rectum, eating out her ass whilst just below Britney was lapping at Sarah's cunt. Sarah was thrilled to have a tongue running into each orifice and she moaned with pleasure into Britney's twat.
After a few moments, Billy knelt up and pushed his cock up into Sarah's ass. He wedged himself up to the hilt in the girl's shitter and began to bugger her slowly, just running his cock to and fro in her shit-chute slowly. He could hear the wet smacking noises of the girls eating out each other's cunts throughout this. He ran his hands over Sarah's back, gently massaging her shoulders as he watched his cock alternately appear and dissapear in the girl's clenching sphincter.
After ten-minutes, Billy slid his dick out of Sarah's ass. The girls shuffled about and switched places, so Sarah was now on her back, Britney on top. With the girls back in a sixty-nine and lapping at the other's cunts, Billy eased his rod into Britney's ass. Once again he went fairly slow, content to take all the time in the world to lovingly sodomize Britney whilst the girl exchanged oral delights with Sarah. Sometimes in the last few days Billy had wondered which of his sisters he preferred fucking the most, but he now realized it was impossible to say. They were as sexy and as hot as each other, both girls just as enjoyable to fuck. They were as horny as each other too - it was never a case that one was more enthusiastic than the other. Sarah and Britney always had the same amount of eagerness to partake in a good fuck. Billy picked up his pace after ten-minutes or so, humping Britney's shitter a bit faster. The girl's picked up their pace too, going from just lapping at each other's cunts to greedily slurping away, thrusting their tongues into the other's womb. Billy's pelvis slapped against Britney's tight buttocks as he fucked her ass.
Sensing his climax approaching, Billy opted to hold himself back. He slowed down and eventually tugged his cock out of Britney's asshole, the child's anus yawning open. Britney got up off of Sarah and the girls moved apart, their inner thighs slick with pussy-juice, as were their smiling lips.
"I love that," Sarah said, "In a sixty-nine with Billy fucking our assholes. We should do that a lot."
"Yeah," agreed Britney, "Pity we don't have another brother then we could both be ass-fucked whilst in a sixty-nine, not just one of us."
"We could always ask dad to join in," laughed Billy.
"Hmmmm," smiled Britney, "There's an idea."
They all laughed, although each sibling did give a few seconds serious thought to this suggestion.
"Anyway," Billy continued, "I'm still hard. I'm about to blow."
"I want you to cum in Sarah's pussy," Britney said, "Then I'll lick all your spunk out of her cunt!"
"Wow, that sound cool," Sarah smiled.
"Okay, lay back Sarah," Billy said.
Sarah did so, spreading her legs wide. Her brother got on top and eased his prick into her twat, burying it in fully. He started fucking her fast, pounding her twat, Sarah reaching round and clenching Billy's ass-cheeks and grunting with delight. Billy fucked away for a minute or two before he shot his load, his spunk exploding out deep into Sarah's pussy. He emptied his nuts up her cunt then withdrew and moved aside.
"Mmmm, some more semen to slurp up!" Britney grinned as she dived in between her twin's legs. She slithered her tongue up into Sarah's cunt and slurped out the sperm, Sarah moaning with pleasure.
"Oh, that's good, yeah," she panted, running her hands through Britney's hair as her sister sucked her brother's spunk out her pussy. Britney did a good job and licked out nearly all the cum, slurping it down, a fine tasting mix of sperm and cunt-juice. She raised her head, smacking her lips and grinning.
Billy held Britney's head and kissed her hard on the mouth, tasting his own cum as he and his sister frenched. Sarah sat up and also had a good snog with Billy before they lay back, Billy in between his sister's, his cock limp across his belly, all of them tired out.
"I hope daddy is out all weekend," Sarah said.
"Me too, otherwise we can't fuck," Billy said.
"Hopefully dad will go and visit his buddies or something," Britney added.
"Well, even if he is around all weekend," shrugged Billy, "We can still screw at night when he's in bed. Plus we'll have all next week too!"
"I hope next week is just as much fun as this week has been," Sarah said.
"I'm sure it will be," Billy promised, "Anyway, time for breakfast. Then we'll fuck for the rest of the day, dad won't be back for ages."

summer
