-------------------------
It was a warm spring day. I had just biked home (as a junior in high school, I didn't have my own car) and raced up to my room to log on to my computer. I eagerly checked my inbox and found the email there: Your Order Has Shipped. The estimated date of arrival was today!
"This thing came for you," said my older sister, Samantha, standing in the doorway of my room. I looked and saw her holding a small cardboard box in her hands. Excitedly I leapt up and took it from her.
"What is it?" she asked, as I eagerly opened the box.
"It's a Plot Device," I explained.
"Very funny." Samantha rolled her eyes at me. She's a year older than me, a senior about to graduate. As is customary, I should also point out that she is extremely hot. She's a star on the school's volleyball team, and today she wore shorts (for the warm weather) and a sports top with a bare midriff (our parents gave up trying to stop her from baring her midriff in public or around the house). "What is it really?"
"It said it was a Plot Device. I found it on the Internet." I pulled away the bubble wrap and examined the device, which looked just like a smooth black box with a bright red button on it. "Apparently, you push the button and the plot advances."
"Plot, you mean like a story?"
"I guess so."
"But you're not in a story. What kind of story would have you in it anyway? You're a geek."
I smiled at her. "I was hoping I'd be in a sex story."
"Ha! Typical." She shook her head. "You're like my boyfriend. Or all guys. All you think about."
All we think about when we're looking at your hot body, I thought.
"How can you be in a sex story when you don't even have a girlfriend?" Sam continued.
"Well, there are stories where a guy gets to do it with his sister," I offered.
Sam laughed. "Yeah, Penthouse Forum! In your dreams, Mike."
I laughed with her. "Yeah, you're right. Well, it can't hurt to try." I pushed the button.
Sam and I both stood there for a minute. I was waiting hopefully for some sign, something. Sam stood there smirking.
"Well, don't believe everything you read on the Internet, Mikey boy." Then her face changed from mocking to serious. "Besides, where do you read those kinds of stories anyway? Penthouse?"
"No, on the Internet."
"Are they hot?"
"The stories?"
"Yeah."
"Yeah they're hot."
Sam closed and locked my door, then walk toward my computer. "Show me one."
She sat down in my chair, I pulled up the extra folding chair and scooted next to her. I opened a browser and brought up mcstories.com.
"You see," I explained, "there are some sex stories where guys get it on with their sisters and stuff because everyone is just really horny and they don't care about incest taboos or anything. That's not very realistic. And then there are 'mind control' stories, where a person, usually a guy, has some way to control people's minds. Of course he uses it to have sex with anyone he wants, including his sisters."
"You think the mind control stories are more realistic?" asked Sam skeptically. She was reading, or really just scanning her eyes over, a story on my screen.
"Yeah, in a way, because there's a single point where you suspend your disbelief. You don't have just accept all these wildly unlikely things are happening. You just accept one thing, like Hypnotic Programming, or a Ring of Power, or an Alien Gift, or a Magic Charm. It's basically a plot device. Like this one." I pointed to the Plot Device box sitting on my desk.
"Uh-huh." Sam was deep in the story. "So in this one, he's wearing a ring, and his sister basically kinda throws herself at him. She's getting naked and letting him do whatever he wants to her. His ring is making her do it." Her voice had changed, with the sound of arousal.
"Yeah, that's typical. Sometime the guy has to talk his sister into it, or hypnotize her. Other times it just makes everyone really horny."
"And now they're fucking. She's doing it with her brother, and she's coming!" Sam's eyes were wide with surprise. "That doesn't happen when I'm with my boyfriend. I mean, I don't come from just fucking. I have to masturbate for that." She pulled her eyes away from the story. "Well you're right, that kind of story is pretty hot. It's too bad we can't do that kind of stuff. Even if you are better looking than my boyfriend. You can't put it in me because that'd be incest."
"We could do some stuff." I offered. "You know, just fool around. I could go down on you. You like that, right?"
Her eyes went wide. "Yeah! OK."
She kissed me, her tongue pushing into my mouth aggressively. My hands went to her breasts, and she impatiently pulled up her sports top and bra to get my fingers on her nipples. We lost most of our clothes on the way to my bed. I found myself naked, on top of Samantha, alternating between kissing her and sucking on her adorable little pink nipples, as her body writhed under me. My hand trailed down to dip into her panties, finding her hand already there.
"Wait," she said, "Do you even know how to eat a pussy?"
"Sure! I've seen it hundreds of time in porn."
"Ha! That figures. OK, go ahead."
I moved down and pulled off her panties, my tongue seeking her clit. I was totally excited. My Plot Device worked! There was no other explanation for my hot sister letting me do this with her. She was really into it, too. She moaned loudly when my tongue made contact, she was already wet, and it didn't seem to matter what my tongue was doing, she just loved it. In under three minutes, she was obviously coming. I slowed down my tongue motions as she swooned and gasped, then kissed my way back up her body.
"Hmmm, you taste like my pussy," she mentioned between kisses. "I guess you're probably totally hard."
"Completely". My erection pressed against her naked thigh.
"And I guess I should help you come too."
"It's only fair," I agreed.
"I guess you could put it in my mouth."
"You'll suck on me?"
"Sure."
"And can I come in your mouth?"
She shrugged. "I guess so. I let my boyfriend do it. It's OK."
I moved up and pressed my cock into my older sister's open, welcoming mouth. Once she started sucking, I didn't last even three minutes. I felt my orgasm starting, clutched at her head and held my cock inside as it filled her mouth. She never lost a drop.
I sat down next to her on the bed, taking in the sight of my sister's amazing body, completely naked, flushed with arousal, breathing heavily.
"Well, thank you." I managed to say.
"Thank you too." She spread her legs a little and a hand trailed down. She pressed two fingers into her very wet pussy, moving them in and out. "It's too bad we can't actually have sex, since you're my brother."
I reached over to my desk and pushed the button on the Plot Device. "And why is that exactly?"
She smiled. "Cause fucking my brother is incest."
"But you're not going to get pregnant, right?"
She nodded, and smiled as if suddenly realizing something. "That's true! I'm on birth control, so it's not like we're going to have a two-headed baby." She looked at me hotly. "Those stories you read, the girl always has orgasms from fucking."
"Pretty much always, yeah."
She pulled me to her. "Lets find out."
So that's how I lost my virginity, to my experienced older sister, in missionary position, on my own bed. Sure enough, she came from fucking, and then her enthusiasm only grew. We fucked in every position on the bed, we fucked standing up, we fucked bending her over against the wall. My athletic sister had no trouble at all fucking me on top, bouncing with youthful glee, my cock just barely reaching bottom each time her clit came down against me. I came once inside her, softened slightly, got sucked quickly back to hardness then we fucked some more. I loved grabbing her strong hips and slamming myself into her doggy-style, and I loved face-to-face where I could kiss her and suck her nipples as I thrust into her.
Eventually we heard noises downstairs and quickly dressed.
---------------
That's how it was for the next few days. After school, my big sister would come to my room, lock the door, and we'd fuck like rabbits. I ate her pussy, she let me come in her pussy and her mouth. Sometimes we sat together at my computer and read things from mcstories. Sometimes she was so horny she even asked to watch porn with me.
We were sitting like that, in my chair at my computer one day. She was completely naked and sitting in my lap impaled, my hard cock inside her, one of her fingers on her own clit, as we watched a scene on my computer screen with one guy and three hot porn actresses, all doing each other.
"That's not very realistic," said Samantha. "I mean, doing it up on the table like that. And what guy gets to do it with three women? And this guy isn't even very good. The women look like they're getting more pleasure from each other."
"The girl-girl stuff turn you on?" I asked.
"Oh yeah totally. Especially if the girls are hot, like in this scene. It's too bad we can't get another girl to have sex with."
I smiled. "Maybe it's in our story?" I reached over and pushed the button on the Plot Device.
"Yeah, right." Sam laughed.
Just then, there was a quiet knock on my door. Sam leapt up, pulling on clothes. I pulled on my pants and went over to the door. "Who is it?"
"Me!" said my younger sister, Sabrina. She's just a freshman in high school, and she's kinda mousy and shy to most people, but in our family, she was pretty bossy. "Let me in."
"Not now."
"Look, I know what's going on. Let me in, or I'll tell!"
Sam and I gave each other a quick glance, then I opened the door and quickly let in Sabrina, closing the door again behind her.
Sabrina took a look at me, wearing just pants, and Samantha, loosely dressed. Maybe the smell of sex was in the air, or maybe we just looked guilty. "I knew it! You guys are having sex in here."
"Don't tell on us!" begged Sam.
"I won't, if you let me watch."
Sam and I looked at each other in surprise.
"You want to watch?" I asked. "Aren't you still a virgin?"
"Yeah, exactly. I don't know much about sex, so I want to see it."
"Well, I'm OK with letting her watch." I offered, smiling at Sam.
Sam nodded. "Sure. But totally secret, all right? Pinky swear."
"I swear." Sabrina looked serious. "Nobody will ever learn from me that you're having sex with Mike."
The two sisters did that gesture with their fingers which was apparently a bond of unbreakable trust between them.
"So, go back to what you were doing." said Sabrina.
"Well, we were kinda having sex in the chair there, watching porn on my computer," I offered, "but you could probably see a lot better if we did it on my bed."
"Yeah, do it on the bed!" Sabrina grabbed a chair and pointed it at my bed.
I took Samantha by the hand. The two of us stood next to the bed, kissing and pulling each other's clothing off again. After some heavy naked petting, I got onto the bed, Sam got on with me on her hands and knees, and she started to suck my cock.
"Wow!" said Sabrina, scooting her chair closer. "My date last year, Sammy, he wanted me to do that."
"Did you?"
"No, I just did it with my hand."
"Like this?" asked Samantha, pulling her mouth back and jacking my hard cock towards her face.
"Yeah. But not aimed at my face. I didn't want his stuff to get on me."
"I let Mike do it in my mouth all the time. I don't mind it," explained Sam. "Here, you want to try stroking it?"
"I guess so." Sabrina pulled up even closer, put out her hand and tentatively put it around my cock. I throbbed in her hand at my first sexual touch from her. Sam gave her tips on how to hold it and how to stroke it. After a minute, Sam put her mouth back down, taking just the tip of my cock in her mouth, as Sabrina stroked the shaft. My little sister, masturbating me into my big sister's mouth.
"You gonna shoot your stuff?" asked Sabrina.
I was pretty close, not from her inexpert stroking but just from the kinkiness of the experience. "Yeah, but you should take your top off. It's not fair that we're the only ones who are naked."
"You want to see my tits, huh?"
"Yeah." I confessed.
"OK." Sabrina stopped stroking long enough to quickly pull off her shirt, and her bra which her small breasts didn't really need, then went back to stroking. I feasted my eyes on her adolescent budding nipples, quickly losing it. Samantha sucked firmly, not missing a drop of my cum as she swallowed.
"Are you going to do it now?" asked Sabrina, pausing as she worked up the courage to say a dirty word, "You know, are you going to fuck?"
"Not yet. He's gotta eat my pussy first." asserted Sam.
Sam lay out on the bed naked, spreading her legs for me as I got into position and started going down on her properly.
"Wow!" said Sabrina, staring in amazement. "I've only heard of that."
"It's so, so good" gasped Sam. I focused my attention on her, losing myself in her labia, my tongue dancing complex patterns on het clit. The next time I looked up, Sabrina and Sam were kissing. I watched in amazement as the kissing got heavier, Sam grabbed one of her own breasts and pulled Sabrina's mouth down to it. Seconds later, Sam started coming like crazy, her hips nearly lifting off the bed.
I saw Sabrina whisper something in Sam's ear as they cuddled through Sam's orgasm. Sam giggled and said "Of course." She turned down to me. "Sabrina asked if she can be next."
"My pleasure," I offered.
In no time flat, Sabrina ditched her skirt and panties and took Sam's place on the bed. I moved up to kiss Sabrina's mouth, then kissed my way down to her perfect little adolescent nipples, then down to her sparsely-haired little pussy. I gently pressed on the insides of her thighs, and she quickly took the hint, eagerly spreading to give me access.
As I ate her delicate little pussy, she made such wonderful little gasps of surprise. Some of them were from the feeling of my tongue all around her labia and clit. I glanced up to see that some of them were from what Sam was doing, sucking on Sabrina's nipples. Soon they were French-kissing again, then when I looked up next they were "titty-nining", Sam hovering over Sabrina, sucking one of her little nipples, as one of her own larger breasts was dangling its nipple into Sabrina's mouth to get sucked.
It took me around five minutes to make Sabrina come.
"Let me try? I want to see if I can do that to her too." insisted Samantha.
"Fine by me," I said, moving aside.
"OK," agreed Sabrina, still woozy from her first orgasm.
I took over the job of kissing Sabrina and sucking her nipples as Sam got into place, eating pussy for the first time, taking to it like a natural. I swear it only took her three minutes to make her sister come! Maybe she was better at eating pussy than me.
Sabrina, drunk with orgasm, still want to see Sam and me fucking, so we did. We got into missionary, and I let Sabrina hold my cock and aim it into Sam's pussy. Then she sat back and watched us go, fucking vigorously for a few minutes of missionary, a few minutes with Sam on top, and then doggy-style.
"That's so cool!" exclaimed Sabrina, sitting next to me on her knees, watching my cock disappearing into our older sister. "You gonna do it inside her? Won't she get pregnant?"
"I'm, on, birth, control" gasped Samantha between pushing her hips back to take my cock deeper.
Sabrina leaned in to kiss me, I felt her little tits pressing against my side as her tongue sought its way into my mouth. One of her hands came down and grabbed Sam's hip, moving along with our fuck. I felt Sam start to come, which was unusual for her to come during doggy-style. That did it for me, I came hard and deep inside Sam.
Sabrina kissed each of us, reiterated her vow of secrecy, pulled on her clothes and left the room.
"I guess the Plot Device worked." I said, as Sam and I cuddled together on the bed.
"It did?"
"Yeah. You said you wanted another girl to have sex with, and it happened."
Sam laughed. "I guess it did. I didn't think it would be our little sister! But I'm glad it was."
I nodded. "I mean, 'Let me watch, or I'll tell on you'? That's the oldest plot twist in the book. My Plot Device isn't very original. Well, I guess it was only fifty dollars on the Internet."
-----------------
The next day, after school, of course Sabrina came to my room again. We insisted that even though she couldn't have full sex (being a virgin, and not on birth control) it was only fair that she at least return the favor of oral sex. So, that day Sabrina took my cock in her little mouth for the first time, accepting a mouthful of my cum, then she turned and went down on Samantha. I contented myself with playing with Sabrina's little pussy, sucking on both their tits as they practiced. Sabrina was a quick learner, bringing our older sister to an orgasm pretty quickly.
Next I fucked Samantha on her back, as Sabrina sat on Sam's face. That led to three orgasms: first Sabrina, then Sam, then me.
After some cuddling, Sabrina wanted to know what porn looked like, so we sat at the computer and watched some.
"Wow!" she said, watching the enormous penises, breasts, and group scenes. "That's crazy!"
"There's lots of sexy stuff here." I said. "Look at this scene, this lucky guy is getting a double blowjob, from two girls."
"What's so special about that?" asked Sabrina. "It's still just a mouth on your cock. I mean it's two mouths, but it's still only one at a time. It's going to feel the same."
"Trust me, it's really a lot sexier than with just one woman."
"Well, we could do it. Sam and me."
"I'd like that." I agreed. "And see now at the end?" I slid the little bar to the end of the video. "See how he comes in one of the girl's mouths, then she passes the cum to the other girl, it goes back and forth, and then they kiss with their spermy mouths? That's called a cumswap."
"But's that's nothing special." Sabrina was unimpressed. "I mean, Sam and I already do lots of kissing, and we've both had your cum in our mouth, so what's special about going from one mouth to another?"
"Trust me, it's really hot and sexy for a guy to watch. And when a guy comes inside a girl, instead of on her face or something, it's called a creampie."
"That makes sense, I guess. It's kinda creamy. But don't you always come inside Sam?"
"Yeah. I guess creampies are really more common in real life than in porn. And then, when another girl licks it up, it's called creampie eating."
Sabrina shrugged. "But that's just like eating pussy, and eating cum. I've done both those things already."
"Yeah, but it's sexier when you do it together, I guess."
"Oh. OK." She watched the screen. "And what's going on there. It looks like it's in her butt!"
"It is. That's called anal sex."
"Do you guys do that?!"
"No." said Sam firmly.
"Not yet." I said optimistically.
"And that other girl... he just took it out of one girl's butt and put it in the other girl's mouth! Isn't that gross?"
"I guess it could be gross," I agreed, "but it seems like porn actresses have some way to make everything squeaky clean. It's called ass-to-mouth. I guess if it's clean enough then it isn't gross, it's sexy."
"Hmmmmm." said Sabrina, unconvinced.
"We could try the double blow-job" I suggested.
"OK." they agreed. I turned off the porn and went back to the bed. I had both my sisters between my legs, naked, on their hands and knees. Sam started sucking, then passed my cock over to Sabrina's smaller mouth. I suggested all sorts of things I had seen in porn: One of them licking and sucking my balls, one licking the shaft as the other sucked the head, the two of them licking both sides of the shaft. I finally lost it when Sam was sucking my balls and stroking my shaft really fast, and Sabrina had just the head of my cock in her little mouth, sucking hard.
"Remember the cumswap?" I asked.
"Yeah! We can do that." offered Sam.
The smile on her face, her willingness, pushed me over the edge, coming hard in Sabrina's mouth.
"Mmm-hmmmm" she moaned with mouth full. Awkwardly, Sam craned her face in and opened her mouth. Sabrina let the cum slip, running down her chin into Sam's mouth. To both my sisters' credit, they actually got the cum back and forth a couple times between their mouths before it was just messy all over and they had to kiss and swallow what was left.
"That's it, you did it perfect, I am totally drained." I gasped, falling back on my bed.
"Cool!" Sam turned to Sabrina. "He's all worn out. Let's go lock the door to my room and 69 on my bed."
-----------------
The next day, my sisters and I were already naked and twenty minutes into a free-for-all of oral sex, kissing and fingering and nipple-sucking, when one of their hands reached for the desk by my bed, looking for a steady surface, and accidentally pressed the button on the Plot Device.
"Uh-oh" said Samantha.
"Uh-oh?" asked Sabrina.
"Yeah. That's Mike's Plot Device. When you push the button, the plot advances."
"What plot?" Sabrina looked puzzled.
I heard the sound of my doorknob turning. In panic, we all reached for clothes, but it was too late. I guess I forgot to lock the door.
Our mom came right in, and took in the scene of the three of us naked, on the bed.
"I knew it!" she declared triumphantly. "You guys are having sex."
We just froze, not knowing how deep trouble we might be in.
"Oh, relax." Mom smiled. "Your Dad and I are highly sexed, we're swingers. I knew it was just a matter of time until you were all having sex. I didn't think you'd do it with each other, though."
"We're not in trouble?" said Sam tentatively.
"Oh yeah, you're in a little trouble." Mom came over to us, staring at our naked bodies. "And quite nice how you all look in your birthday suits. But I understand that Sabrina is still a virgin, and not on birth control?"
"Yeah." agreed Sabrina.
"Well, we'll get you on birth control soon enough. You're old enough to fuck, but I won't tolerate any two-headed babies of incest under MY roof. And you've got to get rid of that virginity. Don't let your brother or some nasty boy do it."
"Um.... how does she do it then?" I asked.
"Gently, with toys. You have toys don't you? Dildos?"
"I've got my little vibrator." said Samantha.
Mom shook her head. "Nope. Alright, come over to my room."
"But... Dad?"
"He won't be home in a while, so you don't even need to bother putting your clothes on."
We followed her down the hallway to the master bedroom. She pulled out a large drawer and the whole thing was filled with sex toys of every size and description. There were some I hadn't even seen in porn.
"Now this is a girl's party, but you can watch, Mike," said Mom. "Pretty soon there will be two girls for you to fuck. And you don't want to fuck me, do you?"
"Um, no!" That had never entered my mind.
"Good, well that's fine. But there's no way I'm going to pass up on sex with my beautiful girls. Who wants to get their pussy eaten first?"
Samantha and Sabrina looked at each other. "Me!" they said at the same time.
Mom laughed, getting between Samantha's legs. I got between Sabrina's. Together, we ate the girl's pussies. When they were close to coming, we switched. Sam came on my mouth, Sabrina came on Mom's.
"I think I like this plot development so far," said Samantha. "God, Mom, you're really good at that."
"I've had a lot of practice over the years," explained Mom, "when your father and I go to swinging parties. Are you ready to return the favor?"
"What, you mean ... to you?" Sam looked uncertain.
"Yes. Are you comfortable with that?"
Sam shook her head. "No, I guess, I mean ... you're not a girl. And you're my mom!"
"You were OK with letting me go down on you."
"Yeah, but .. you .. down there .. I mean, that's where we were born from."
"That's true. You may not have known that your Mom is a kinky slut. I've let men, women, anybody eat my pussy. But it would be much more exciting and meaningful if it were you, my own sweet daughter."
"OK, fine." Sam gave in.
"I'll do it too," offered Sabrina quietly.
"Oh, my beautiful girls! I'm so proud of you. Come to me." They all kissed, Mom sucked on their nipples, then she was pulling off her skirt and panties. Pretty soon both my sisters were on their hands and knees, between Mom's legs, eating her pussy together. I watched for a bit until I couldn't take it any more, getting behind Samantha and pushing my two fingers into her tight wet pussy, and one finger into Sabrina's virginal tightness. Pretty quickly Mom came.
After a lot of kissing between them, Mom grabbed some toys and she and Sam worked together on gently penetrating Sabrina's virgin pussy, bending her hymen with their fingers and a toy. I guess Sabrina was already a little loose, because she didn't seem to be in much discomfort by the time Mom got the decent-sized dildo into her little pussy. It probably helped Sabrina a lot that Mom was French-kissing her and Sam had her tongue dancing on Sabrina's little clit as the dildo went in.
They kept going until Sabrina had a little orgasm with the toy inside her. Sam cried out with excitement as having succeeded and they all kissed each other a lot through the aftermath of the orgasm.
"Oh, you poor boy," said Mom looking over at me, sitting at the end of the bed with my hard cock bobbing. "You must be going crazy. Come here and have sex with Samantha, why don't you? I want to see my children fucking. I've been going crazy listening to you guys already."
"You could hear us?" I asked, as Sam got on her back and spread her legs for me.
"Of course, silly. The walls aren't that thick. The sound of sex carries. I heard you and I knew you were fucking. I had to stand by your door and masturbate myself, it was so hot to imagine you two together. Now I want to see it."
"No problem!" I said, getting between my older sister's legs. I sat up a little at first, so that Mom could watch my cock going inside of Sam, then I relaxed and got busy in a steady, classic missionary position fuck.
"That's so, fucking hot." gasped Mom. "Here Sabrina," she pulled the girl up to her, "put some fingers in my pussy and suck my clit while I watch them fuck. That's a good girl."
By the time I was close to coming, Sabrina had her whole small hand in Mom's pussy.
"Wow!" said Sam, turning her head to see where her sister's fist was.
"Can I come now?" I asked.
"Go ahead," said Mom, "I was thinking of asking you to do it where I could see it, but it's kinda sexier for you to do it inside your sister's pussy. Sabrina sweetie, you've tasted your brother's cum, right?"
"Sure." Sabrina was still moving her hand gently in and out.
"Have you tried drinking it right from your sister's pussy?"
"No, but I know what that's called. Mike told me when we were watching porn, that's called creampie eating."
"That's right! Wow, how fast children grow up nowadays with the internet. Will you do that for me, sweetheart? I want to see you eating your brother's cum from your sister's pussy."
"Sure, no problem."
"Oh, my sweet girl. You are so sexy, you turn me on so much." With that, Mom came on Sabrina's fist, and a second later I came inside Sam.
Slowly they untangled, and Sabrina took my place between Sam's legs. Sam's pussy was really wet and messy, with her pussy juice and my cum trickling out. Sabrina started licking everywhere, then fastened her mouth on Sam's hole and used suction and her tongue to get all my cum.
"Oh, that's so hot," gasped Mom. "You are such a beautiful, sexy girl. I just have to fuck you! Why don't you girls get into a 69." With that, Mom rummaged in her big drawer of toys and strapped on a dildo, as my sisters got into 69 position, with Sabrina on top. Mom got behind Sabrina and pushed her fake cock into Sam's mouth at first to get it wet, then gently into Sabrina's freshly de-virginized pussy.
"Lower your hips, sweetheart," said Mom to Sabrina. "Push your clit down there on your sister's mouth, I want her to suck your clit while I fuck you. I want to make you come this way." She looked up at me. "Mike, there's a pussy and mouth available there on the other side."
I smiled and took my position, moving my cock back and forth between Sam's pussy and Sabrina's mouth. Sabrina wasn't really sucking, since all of her attention was on the sensation she was getting at the other end. Both girls made wonderful moaning noises as Mom and I fucked them.
"This is fucking awesome, Mom." I said.
"I know! I'm so happy you kids turned out as sex-crazy as your father and I."
"Does this mean we can stop hiding in my room when we do it?"
"Maybe. You can do anywhere as long as your father isn't around. I don't want him to know you guys are having sex yet. If he hears about it, he's going to want to fuck the girls, and I'm not ready to share them yet. So, only when you know for sure that he won't find out."
"OK." We thrust together for a minute, listening to the girls moaning. "Can you tell me why you're doing that, fucking Sabrina? I mean, you can't feel inside her where your strap-on toy is."
"That's true, but the other end of the toy is brushing my clit every time I thrust. And it's just sexy as hell for me to fuck my very own, gorgeous, sexy, virgin daughter. Besides, she's loving it, and it's not safe for you to fuck her yet. Where are you going to come?"
"I want to do in Sabrina's mouth."
"That's great, but wait until she comes. I want her to come first, then she can drink you."
I concentrated on fucking Sam, trying not to think about the sexy scene in front of me for a few minutes.
"I'm.... coming...!" said Sabrina suddenly.
I grabbed Sam's hips and gave her tight pussy a few more hard, deep thrusts until I felt my orgasm starting, then quickly moved up to Sabrina's mouth, stroking my shaft just a little then letting the suction of my little sister's mouth take over as I let her drink my cum.
We slowly untangled. "I want to take a shower with Mike," said Sabrina.
"Go ahead sweetheart," encouraged Mom.
"And I still haven't come yet, "said Sam. "Can you do that thing for me, Mom?"
"You want me to fuck you to orgasm with my strap on? You bet I can!"
They were quickly and happily bouncing in their mother-daughter fuck as Sabrina and I walked hand-in-hand from the room down the hallway, into the shower. It was my first time in a shower with a girl and it was a lot of fun, even though we were temporarily sexed-out, there was still a lot of playful groping with soapy hands
-----------------------------
The next day, after school, I biked home and went up to my room. I knew Samantha had some athletic practice that day, and I didn't know where Sabrina or Mom were, so I just sat down at my computer and pulled up some porn. I considered beating my meat, but then I looked at the Plot Device sitting on my desk. I pondered it. The last time we pushed the button, by accident, things had taken a wild curve with our Mom. What would happen next? Was I ready for it?
I smiled to myself and reached over and pushed the button.
A minute later there was a knock on my door, then Sabrina let herself in. She was wearing a miniskirt and a T-shirt. It was obvious there was nothing under the T-shirt, and when she came to my desk to kiss me, I put my hand between her legs and found there was nothing under her skirt either.
"I think you came to my room for sex," I said.
She giggled, "Yeah, I'm horny but I know we can't really do it yet. Can I sit in your lap and watch porn with you?"
"Sure!"
She removed her mini-skirt. I pushed my pants down to my ankles and she sat down on me, both of us facing the computer. My half-hard cock nestled between her inner thighs and her damp little pussy.
"What do you want to see?" I asked.
"I want to see anal sex."
"OK." I clicked a couple search words and brought up one of my favorite scenes, with Nacho Vidal and Jazmine, from Tristan Taormino's Ultimate Guide To Anal Sex For Women.
"Wow." Sabrina wiggled in my lap as we watched the couple on screen. "He just puts it right in there."
"Well, I'm sure it's not that simple. I other parts of this video they talk about how to start slowly and get it warmed up."
"And he's huge!"
"Well, yeah Nacho is big. He's a professional, but then again so is Jazmine. I think that's actually his girlfriend in real life. She's had tons of practice at taking his huge cock in her ass."
"You're not nearly as big as him."
"Yeah, thank goodness."
My hand were under Sabrina's shirt, my fingers playing with her nipples. She had one hand between her legs, touching her clit. I kissed the side of her neck and she wiggled her hips again, subbing against my hard cock.
"I bet we could do that."
"What, anal sex?"
"Yeah."
"I'm not sure. You're only 14."
"15 next month. And I really want to have sex with you and I have to watch you do it with Sam and it looks so good and you're my favorite brother."
"I'm your only brother."
"Exactly. You want to do it, don't you? It's sexy, right?"
"Sure, it's super sexy. I'd love to have anal sex with you, but .. I don't want it to hurt."
"Don't worry. I already asked Mom about it and she already told me all about it and gave me some stuff."
"Oh. OK. I guess we could try it then?"
"Goody!" Sabrina got up and gave me a quick kiss, dashing out of the room and returning with a bottle of lube. She pulled me to the bed, spread her legs wide, and put a pillow under her hips. I got in place between her legs as her instruction and started eating her little pussy, then slowly started to introduce a lubed finger in her incredibly tight little butthole, then slowly added another finger.
Sabrina was breathing heavy. "Yeah! Just keep doing that! Oh that feels weird, but kinda cool too. I think I'm going to come."
It took several more long minutes, but pretty soon I was able to thrust my two fingers in and out easily, and she did come, wetly, while I had her whole little clit sucked into my mouth.
"OK, let's do it now," gasped Sabrina.
I got into position, my cock resting against her pussy. It was so, so tempting just to push myself into her wet pussy, but I controlled myself. Instead I thrust my cock along her slit, the underside of my cock getting wet and rubbing against her clit.
"Oh! Wait a minute, that feels good but it's too sensitive! Go ahead and try putting it in my butt."
I lubed up and put myself at her back entrance. Her eyes went wide as she felt the head of my cock go through her sphincter. Once she was comfortable there, it was a simple of matter of going in really, really slowly. Pretty soon I was all the way in, buried to the hilt, with my pelvis pressing against her clit. I was also face to face with her so we were kissing.
"You're totally inside me!" she gasped between kisses. "You're fucking me!"
"Yes I am. God, you are so, so hot and tight!"
"Does it feel good?"
"Way, way better than good. I'm right on the brink of coming and I'm not even moving inside you."
"That's OK, you can come inside me."
"But I want it to last longer!"
"Don't worry." She kissed me. "We can do it again real soon."
I started to move and sure enough, in just a few half-strokes I was coming.
"Wow!" Sabrina kissed me "I can feel it! I mean, I can't feel the cum but I can feel you getting bigger and throbbing inside of me. It's like, you've taken my anal virginity." More kisses. "Can I be your girlfriend?"
"But you're already my sister."
"Yeah, it'd have to be a secret. Even from Sam, because she'd be jealous. Can I be your secret girlfriend?"
"OK."
"Good. I love you." More kissing. "Can we take a shower together again? I really liked that yesterday."
"Sure!"
We slowly untangled, and walked down the hall to the shower. Sabrina brought the lube with her. In the shower, we washed and fondled and kissed under the hot water. She took especially good care of washing my cock with soap and lots of hot water.
"I guess you're clean now," she said with a smile, bending over and taking my hard cock in her eager little mouth. Her hair was getting wet, but she didn't seem to mind. I just swooned and put my hands on her head, guiding it up and down even more quickly.
"Don't come in my mouth," she said between sucking. "I want you to put it back in my butt."
"Right here in the shower?"
"Yeah! Like from behind."
She released my cock, stood up, turned away from me, spread her legs slightly, tilted her hips back to lift her beautiful ass up to me, then reached back to spread her cheeks, showing me her back hole.
"I think it will work like this." she suggested.
I nodded, reaching around the shower curtain to grab the lube bottle. I was rock-hard and extremely slippery as I pushed myself slowly into her.
"Oh, yeah!" She giggled, then moaned. "Butt-fuck me, Mikey."
I did, very slowly and carefully at first, then gradually building up speed and pressure as she got used to it. I had my hands on her hips, the hot water beat down on us, and I was soon fucking her ass as strong and deep as I was used to fucking Sam's pussy.
"Does that feel OK for you?" I asked.
"Yeah! It's really intense, but it's kinda good too. I like making you come. Are you going to come?"
"Yeah, I'm close."
"Good! I want you to come deep inside of me, deep inside my butthole. I want you to use my body and make me your girlfriend."
I did, and then we slowly calmed down and hugged and finished washing and got out.
That night, when I was getting ready to go to sleep, Samantha came into my room.
"Hey, Mike." She sat the edge of my bed. "I heard about you and Sabrina."
"She told you?"
"Yeah. You know, I'm jealous."
"Because we did anal sex?" I smiled. "Do you want to try anal with me?"
"No, I'm not ready for that yet. I mean, now you're doing it with her, and she's younger, and cuter, and tighter than me. Are you still going to want to have sex with me? I don't want to go back to my old boyfriend."
"Are you kidding?" I reached for her. "You are probably the hottest girl I know. You've got a hard body, awesome tits and you love to fuck. And you're my big sister. I'll always want to have sex with you."
"How about now?" she said smiling, pulling off her top, her breasts springing free.
"Hell yeah!" I threw back the covers. Her mouth went straight for my cock, taking it surprisingly deep and sucking me quickly to hardness. Her panties came off in a flash, and I was on top of her and buried to the hilt in her already wet pussy.
"You know, I'm always going to want to fuck both of you, especially together."
She giggled. "Yeah, of course. Two hot girls is better than one, right?"
"Generally, yeah. Although both of you are perfectly hot, one-on-one like this too."
"You like watching us do the girl-girl stuff too, don't you?"
"Yeah, totally."
"Good, because I love that stuff too. I don't care what crazy sex stuff you come up with. I'm happy to do anything with you, with her, or with both of you, anytime, anywhere." She giggled. "I want to be your slut." We kissed as I thrust into her. "Hey, you pushed the button again, didn't you? Before Sabrina said she wanted anal sex?"
"Yeah, I did," I admitted. "Apparently, the Plot Device decided that my little sister wanting to get ass-fucked was the next plot development."
"I wonder what would happen if we pushed in again. I'm kinda scared, actually. You don't think Dad would want to have sex with me, do you? Like Mom said?"
"I don't know. Maybe we should put the Plot Device away somewhere safe where the button won't get pushed by accident."
"Maybe we should."
I fucked her through one (or perhaps two?) of her own orgasms, before I got close.
"Do you want to do it in my mouth?" she asked. "I'm about to go to bed, and if you do it in my pussy it'll be messy, dripping out of me all night."
"Sure. You mean like, when I'm ready, just get it up to your mouth in a hurry?"
"Yeah!"
I did exactly that, waiting until I felt it coming, then pulling out quickly and scampered up, getting it in her tight sucking mouth just in time for the blasts to get safely swallowed. No mess.
-------------------------
It took me a little longer to get home the next day from school. When I came in, there were sounds of sex coming from the living room.
"Come on in, Mikey?" called my mother's voice.
I walked in and stopped short at the sight that greeted my eyes. Mom sat on the sofa, wearing a bustier and stockings. Sabrina sat in her lap, completely naked. Sam still had her clothes on, but was on her hands and knees, her face between their spread legs. Mom had her hands on Sabrina's little tits, and was kissing the side of her neck as they hips moved slowly.
"Come see what we're doing!" said Sabrina excitedly when she saw me.
I came in for a close look. Sam pulled her face back so I could see. There was some kind of dildo-like toy, with a fat end that disappeared into Mom's pussy. The other end was skinnier and it was going right up Sabrina's little ass. Sam's mouth was right in there, licking and sucking our little sister's pussy and clit.
"I heard about yesterday," explained Mom, "about Sabrina getting anal. So I asked her if she wanted to try it while getting her pussy eaten at the same time."
"Of course I said yes!" giggled Sabrina.
"That's totally hot." I agreed. "I guess I could just watch?"
"I see your sisters have at least a mouth and a pussy available?" suggested Mom.
I smiled and nodded, dropping my pants and underwear. Sabrina eagerly opened her mouth. She was already woozy with lust, perhaps on a plateau between orgasms, so her mouth was kinda relaxed as I held her head and gently fucked her little mouth. When I was wet and super-hard, I moved down to Sam who was on her hands and knees on the floor. She eagerly wiggled her hips to help me pull her shorts and panties down, just far enough that I could get behind her and fuck her doggy-style.
"This is so wonderful, so fucking hot!" gasped Mom. She had her hands moved down to Sabrina's hips, helping her rock gently, moving the little toy just a little in and out of their holes. "I get to make my little girl come by fucking her in the ass! And watch my oldest children fucking in front of me on the living room floor! I am so NOT ready to share this with your father. I want you all to myself! How wet is her pussy, Mike?"
"Smooth and wet, Mom." Each time I bottomed out in Sam's pussy her face mashed against Sabrina's pussy. "She's really into it."
"I'm ... I'm coming again." gasped Sabrina quietly.
I held myself steady and Mom hugged Sabrina as her little body gently trembled.
"You want to take a turn, Mike?" asked Mom. "Come take my place. I want to see your cock going up your little sister's ass."
"Are you OK, with that, Sabrina?" I asked. "I might be a little bigger than that toy."
"Yeah. I want more," said Sabrina quietly.
I got rid of my remaining clothes and sat down on the sofa next to them. Very carefully, they helped Sabrina sit up, then helped her to sit back down in my lap. I couldn't see exactly, but I felt Samantha giving my cock a few wet sucks then using her hand to aim it, lining the tip up at Sabrina's little rosebud. Sabrina gave a long, quiet sigh as she lowered herself down, impaling herself on me.
I felt Sam's tongue licking my balls, then just her hot breath as her tongue must have moved up to Sabrina's pussy. Mom sat next to us for a while, French-kissing Sabrina and giving us advice on how to move together slowly, just an inch of my cock pulling out of Sabrina's ass then pushing back in. Pretty soon Sam complained that nobody was fucking her, so Mom got down there, switched out a different toy between her legs, and used it to fuck Sam doggy-style.
"Yes, yes, yes," gasped Mom as she slammed her toy into Sam. Mom's eyes were transfixed on the sight of Sabrina, naked and wiggled her hips on my lap. "Yes, good boy, fuck your sister, fuck her tight little asshole, fuck her and make her come again and again, fuck her and pump your hot cum deep in her ass, make her pussy come on her sister's mouth, make her sister drink all her girl-cum, drain your balls in your little sister's ass..."
I could feel my orgasm approaching. Only with pure concentration was I able to hold it off for another two minutes, long enough for Sabrina to work her way back to an orgasm of her own. When she came, it was too much for me, I had to let go. Incredibly, her ass was so tight, I was coming but I couldn't actually ejaculate! Her sphincter gripped me like a cock ring, stopping the cum partway. It felt amazing, an agony but also an ecstasy. Only when Sabrina's orgasm passed did her sphincter relax enough for me to actually deposit my cum in her ass.
"I wanna shower with Mikey," said Sabrina softly as we slowly untangled our bodies.
"No way. You got to do that yesterday. It's my turn." insisted Sam.
"Now, now, don't fight. Your brother has only come once today so there's plenty of him left. Sabrina sweetie, do you mind giving your sister a turn? I want to take a shower with you myself."
"Oh, OK." pouted Sabrina.
"Oh good!" Samantha took my hand, leading me towards the second bathroom. "I want you to fuck me in the shower and make me come standing up!"
As we walked away, I overheard Mom saying quietly to Sabrina, "Now that you're an anal girl and you let your brother ass-fuck you standing up in the shower, I want to try doing that to you too...."
