My name is Paul and I'm 18-years-old, just about to start University. I was to study Economics, something that I was moderately interested in and also that would hopefully lead to a good job. By lucky chance, one of the colleges that accepted me was here in this city, across the country from my parents home, the luck being that my older sister Gemma lived here.

My sister and myself had always been close and she was happy for me to stay with her and her lover. The pair of them shared a large, single-storey house in this street, set in a big tree-filled garden. Gemma worked as a PR agent for a large company in the city-center, her sweetheart also working in the same company.

Soon I was walking up the garden path and I placed my cases on the ground and rang the doorbell. My sister, I knew, was working late tonight until about 8 o'clock, and so her live-in lover answered.

"Hiya," Tammy grinned when she opened the door, "You were a little later than I thought Paul, I was getting worried."

"I walked from the station," I told her, "Bit of a mistake, I'm whacked! Shoulda got a taxi."

"Yeah, it's further than you think," Tammy explained, "Trying to be macho were we? Or saving your money so you could have more for beer money?" She beamed a smile at me, which I returned.

"Gonna give us a hand then?"

"Sure."

The young woman took one case and I grabbed the other, then we both lugged them into the house, me shutting the door behind me.

The home was very open plan, with the hallway leading into one large, L-shaped room that took up most of one-half of the house. It contained the kitchen area, a large dining table and, where Tammy and myself now were, the living room area. The two bedrooms and bathroom were on the other side of the hallway.

"Shall I dump this here?" Tammy asked, then without waiting for me to answer, dumped the suitcase next to a bookcase. I placed my case there too and went to slump down onto the black leather sofa that sat underneath a big bay window at the front of the house. The curtains were open, giving a view of the lawn, the trees that blocked off sight of the road, and a beautiful Autumnal sunset. Before the sofa was a solid-oak coffee table, beyond that another leather sofa, and to the right a huge TV.

Very nice,I thought to myself. This would definitely beat student living, and was cheaper too, my sister - generous as always - being reluctant to accept any rent money. With savings and a part-time job lined up, I'd insisted that I at least pay her for food and heating, which still left me with more spare cash than an average student.

"This place looks even better than the last time I was up here," I commented, "Is there something new here?"

"Yeah, the sofas," Tammy said, "I thought you'd notice them as soon as you came in!"

"Well, I'm a bloke. I don't really notice such things when it comes to interior decorating."

"You think it looks nice though yes?"

"Absolutely. Nice Nirvana picture," I commented, the picture of the band being a poster hung on the wall in a large, chrome poster-frame.

"Yeah, you like them?"

"Sort of. A bit old fashioned for me."

"Old fashioned!" gasped Tammy, "I was 17 when they made it big. You're making me feel old!"

"You're not old," I reassured her. Tammy had turned 27 a few weeks ago, her self-consciousness about her age heightened by having a girlfriend three years younger than herself, and now myself, only 18, as a housemate. I don't know why she was concerned; she was naturally pretty and in good shape.

"Want some coffee or anything?" she asked me, "Or a beer?"

"Coffee will do," I said.

"Comin' up," Tammy responded, and sauntered off to the kitchen area at the other end of the room where, with her back turned to me as she fetched a couple of cups from the pine, fitted cupboards, I watched her idly.

Average height and slim, Tammy was very attractive with big brown eyes and long black hair reaching to her waist. She was dressed casually in jeans and a white T-shirt, and even though she was a lesbian who was my sister's partner, my naturaly male instinct was to look at her fine, firm arse within the tight blue denim jeans as she made the coffee.

My sister, Gemma, had 'come out' when she was 19, and though our parents were not wildly liberal, they were fairly open-minded and hadn't been particulalry bothered or critical. My mum had suspected anyway her daughter was a lesbian for a while, and had relayed these thoughts to dad, which meant the blow was softened. Tactfully, my sister waited a few months from then before bringing her first girlfriend home for dinner witht he folks, and everything went along smoothly. Gemma, in fact, was really bisexual. She'd had a couple of boyfriends after coming out, one of whom she was with for almost half-a-year. But she was primarily inclined to 'bat for the other side', as the euphamism, and at 20 she dropped out of college and got a job as a PR agent for a company. Tammy worked in a similar role for a different company on the outskirts of the city.

Like my sister, Tammy had been out with a couple of guys in her late teens, but also like Gemma she preferred female companionship when it came to long term sexual and emotional relationship. Now they'd been going out together for almost four years, and within the young women's circle of friends and their respective families, they were regarded as much as a couple as if they'd been married.

When Tammy had made coffee for us both, she turned and walked over towards the lounge area, where I'd grabbed a TV-guide to flick through so that my host wouldn't think I'd been staring at her arse for the last couple of minutes.

"You been staring at my arse for the last couple of minutes?" Tammy asked, cheekily, as she placed the cups on the table and sat next to me.

"Of course not," I protested, "I'd do no such thing!"

We both laughed, the way people do at silly, personal jokes. When I came to visit here for the first time last year, Tammy had sunbathed topless in the garden and I'd come out to ask her something. She'd lain on her stomach on a towel, eyes shut, a G-string bikini bottom on and nothing else. I'd paused, wondering whether to disturb her whilst transfixed by he sight of her lovely, fresh arse-cheeks. However, Tammy's eye's had not been closed behind those sunglasses she'd wore, and she'd made a sly comment "Enjoying the view?" I'd been embarressed of course, but Tammy had laughed it off, regarding it as utterly normal behaviour. "A teenage boy who doesn't cop an eyefull of a nice ladies' bum presented to him is the weirdo, not the one who does" she'd insisted. Tammy had told my sister too, who'd cracked a few daft jokes at my expense, which was a lot better than being branded a pervert which is what I'd feared originally. Now, it was a private joke to Tammy, who often asked - with mock indignation - as to whether I'd been looking at her arse. I always said 'no' and laughed along with her, wondering whether she knew that, most of the time, I'd been doing just that. I may have had a few girlfriends, and fucked a few, but Tammy was really pretty and sexy and I couldn't help but eye her up.

We sat and sipped our coffee, exchanging chatter about recent events, my ambitions for college, Tammy's recent promotion and so on. Shortly, the a car pulled up outside and soon my sister was entering the house.

"Hey Paul!" she cried, excitedly, pleased to see me here even though it was expected. I stood up from the sofa and Gemma hugged me, kissing me a couple of times on the cheek.

"Hiya sis, you okay?" I asked.

"Fine, fine, yeah," she replied, "Boring old work. Nevermind that though, how are you? This is gonna be great, me and you living under the same roof, like when we were kids."

Gemma stepped back from me, and I couldn't help but be touched that she was pleased that I was here. We had no other siblings, and with out parents having had busy careers that involved being away a lot, Gemma had babysat me a lot more than an average sister would've done. I wouldn't say she was a second mother as such, but we were as much close friends as we were brother and sister.

"Any coffee on the go?" Gemma asked, walking towards Tammy who still sat on the sofa.

"There's some in the pot," Tammy replied, and Gemma bent down to kiss her on the lips, a quick, routine peck you'd expect of a couple when one of them returns home.

I couldn't help but be a little turned on, even though I'd seen them kiss like that before. My 24-year-old sister was, even aside from my biased opinion, very pretty. Like Tammy, she was average in height and slim, but otherwise they contrasted with each other physically. Whilst Tammy was dark-haired with dark eyes and a sharp, elfin face, Gemma had shiny blonde hair, wide blue eyes and a full mouth. Dressed in a dark-grey business suit, Gemma's trousers hugged her arse, which was round, firm and shapely (a bit of a lewd observation for a brother to make, admittedly, but a testosterone-wracked boy can't help but notice). Tammy was fairly flat chested, and whilst my sister wasn't necessarily 'top-heavy', she did pack a fair sized couple of tits in that silk blouse she wore.

"Excellent," my sister said, heading towards the coffee pot in the kitchen area, "Anyone want refills?"

"Yes please," I called.

"Not for me," said Tammy, "I don't wanna be awake all night. Some of us," she continued, looking at me, "aren't students who have three years of sleeping until lunchtime and drinking beer whilst watching daytime soap-operas ahead of us."

"You're just jelous," I insisted, "Besides, you went to college Tammy, you had your slothful fun."

"Ignore Tammy," my sister advised as she poured herself coffee, "She's an old sourpus who's jelous of youth. Quarter-life crisis they call it."

"Oh shut it you," Tammy retorted, then stuck her tongue out rudely at Gemma, both of them breaking into giggles. I'd met Tammy a lot in the couple of years she'd known Gemma, so I felt as comfortably informal with her as I did with Gemma.

My sister was soon sitting back on the sofa, Tammy on one side and me on the other.

"This is going to be great with Paul here," she commented.

"A nice cozy household," Tammy agreed, "We should assign roles, you know, like if this was a traditional house. Paul would be the son. I'd be the mum and you can be the dad Gemma."

"Why am I the dad?"

"I dunno," shrugged Tammy, "Okay, I'll be the dad, you can be the mum. You think that's okay Paul?"

"Fuck knows," I smiled, "Gemma's my sister, so I'm not very qualified to determine if she's the mother or father of the household."

"Paul should be the dad," Tammy insisted, "He can put up shelves and mow the lawn. We'll be his daughters...and he's got to spank us if we're naughty."

We all giggled.

"We don't need to pretend such childish things," Gemma announced, placing one hand on Tammy's thigh, her other hand on one of mine, "It's a cozy enough set up as it is. Me, my lover and my kid brother."

With the TV on in the background, we chatted for a little while. It was Sunday evening and the two ladies I'd be sharing a house with had work in the morning, whilst I had induction week at college. So, after sharing a small bottle of wine, we made moves for bed.

"Will you get round to unpacking tomorrow," Gemma asked me as we got off the sofa together, "Tammy's a bit fussy when it comes to tidiness and will hate seeing suitcases lying around."

"Cheek!" cried Tammy, "It's you who's fussy Gemma! Don't listen to your sister Paul."

"Don't worry girls, I'll unpack tomorrow evening," I reassured them, "Me first in the bathroom."

I hurried off before they could protest, having a quick shower and brushing my teeth. As I came out, Tammy went in, carrying some silk, pink pyjamas in her hand.

In the living room, I retrieved my suitcases and headed towards my bedroom, which entailed walking past the open door to the room Gemma and Tammy shared. I heard my sister humming in there and I slowed as I went past to say one last goodnight. As I drew level, however, I peered in and saw my sister naked, facing away from me. She was at the dressing table, removing her make up, the mirror angled so that she was unable to see me. Because she was sitting down, I didn't see much (not that I wanted to, I lied to myself, shirking off such incestuous voyeurism) but I briefly appraised her bare back and her rounded buttocks which perched on the soft pink stool at the table. With her humming still eminating from the room, I walked on, entering my room and closing the door.

The following week went by smoothly. I settled into college, made a few friends and snapped up all the necessary books I required for the course. Things were fine at my sister's house too - or rather 'home', as I should now call it.

I was still a little titilated when I caught sight Tammy and Gemma kiss when they parted in the morning or met up in the evening (Gemma got home a little bit later than Tammy). They usually cuddled up to each other on the sofa whilst I sat on an armchair reading up on my homework, glancing out of the corner of my eye and catching them kissing during the advertisment breaks on TV. One morning, I strolled into the kitchen area where the two of them - Tammy in a fluffy white gown, Gemma in a skimpy, satin negligie - kissing quite passionatly against the worktop. Determined not to make a big deal of it, I simply strode up to the coffee machine and cheerfully greeted them with "Good morning sweethearts". The pair had reacted in a similarly casual manner, ceasing their kissing but remaining in each other's arms as I made us all some coffee.

On Friday evening, Gemma had drank a bottle of wine whilst watching some TV and had gone to bed at 10:00PM. I remained slumped on the sofa, clutching a single bottle of beer whilst watching TV. Tammy had gone for a shower earlier, and I was waiting for some trash sitcom to end, waiting for the movie Aliens to come on afterwars.

I heard Tammy leaving the bathroom down the hallway, and I did a double-take when the bisexual woman entered the lounge. She was wearing nothing put a skimpy, black thong, a dressing gown draped over her hooked left arm whilst in her right hand she held a towel which she rubbed her hair dry with. I looked away, a little embarressed, but unable to resist turning back to admire her - those firm, tanned legs, those tits, small and pert with big, dark-brown nipples. Fuck! My dick began to stiffen.

"Anything on?" Tammy asked, dumping the gown on the floor and sitting on the sofa opposite, still drying her hair.

"Just this," I replied, trying to sound casual, "Then it's Aliens on after this. Good movie...you seen it?"

"Not for a while," Tammy said, then finished drying her hair. She obviously sensed my nervousness, the way I sipped at the beer bottle even though it was empty, whilst paying undue attention to the TV adverts.

"You okay?" she asked.

"Sure," I shrugged, "Though, you know...a little distracted."

I looked at her, Tammy quickly catching on that she was sitting opposite me virtually naked.

"Oh shit, yeah," she began smiling, "Sorry. Force of habit, I'm not used to covering up in here. Sorry."

"No, it's okay," I insisted, then decided to state things honestly "It doesn't bother me. It's...well...Shit, I'm a teenage lad, you're a rather sexy young woman and you're wandering around topless. I know you're my sister's girlfriend and all that, but I can't help but respond in a predictable manner. I don't want you to feel as if you can't wander around naked in your own house - hell, I'd be lying if I insisted that you cover up because it bothered me - but at the same time I don't want to offend you by springing a stiffy if you choose to, you know...wander about...as nature intended."

"It's very nice of you to be so forthright," Tammy replied, serious for once, "Me and Gemma obviously don't bother covering up in here, and the only other guests we've had were two gay friends last year who stayed for a week. Obviously, neither batted an eyelid if we strolled from the bathroom nude. A lot of our male friends are gay so I'm not used to causing 'stiffies' by exposing myself. I'll keep things under wraps if you want. Or would you prefer I wander about naked?"

She grinned at me, but her question nonetheless wasn't entirely rhetorical

"You have a very nice body," I simply said, inwardly congratulating myself for saying it how I meant it - not a tacky come-on or a simple compliment, but rather a genuine statement.

"Thank you," Tammy smiled. She stood and put on her dressing gown, unhurridly, turning away from me as she did so and - deliberately? - giving me a good view of her arse. The thong meant her cheeks were fully visible, as firm and shapely as they appeared when I happened to catch a good look at them last year when she was sunbathing.

"I hope you've not been perving at my arse," Tammy asked, now with the gown on and tying the belt as she turned round.

"I was," I answered, and we both smiled. Tammy plonked herself down on the sofa next to me.

"It's been years since I've seen this movie," she said as the film began on TV.

"Same here, it's one of my favourites."

We both settled back, all tension eliminated and feeling utterly comfortable in each other's presence.

The next day, Saturday, Gemma was in the kitchen early in the morning wearing her pink, satin night-dress. It was low-cut, revealing a fair bit of cleavage, and the hem ended half-way down her thighs, showing off her legs. She wore a pair of white slippers with bunny-rabbit faces on.

"Hi sis," I said as I walked up beside her.

"Morning Paul," she smiled, "Want some breakfast? I was just about to make some waffles."

"Yeah, sure. You up to anything today?"

"I was going to see a friend of mine. What about you?"

"Nothing planned," I shrugged.

"Tammy's going to do the grocery shopping. You could help her if you want."

"Okay."

We both made breakfast, including something for Tammy who appeared shortly, yawning and dishevelled.

Showered and changed, Gemma later left the house in her car, whilst Tammy used her car to drive to the supermarket, with myself in tow.

Whilst I'd always considered Tammy a good friend who I could be honest with, since last night's encounter we felt even more at ease with each other. We chatted amicably as we wandered round the store on the edge of town, stocking up with food and hauling it to the checkout, then to the car, and probably being mistaken for boyfriend-and-girlfriend (or man and wife!) as we went.

We had to skirt round the city-center on the way home and I had no objections when Tammy said she wanted to stop at a shop on the way.

"Which shop is it?" I asked.

"A sex shop," Tammy replied, weaving the car through the building traffic.

"Oh," was all I could respond with.

"You don't mind do you?" Tammy grinned, and I smiled back.

"Nah, not at all. I've only been to one once, earlier this year, to buy a porn mag. It's really embarressing going in."

"Yeah, I know. I've been in this one a couple of times, for videos and other stuff, and on each occasion a customer and the guy behind the counter tried to chat me up. It's like any woman who goes in there is desperate for sex with any man."

I nodded, realising that that was the opinion I'd have held if I saw a woman on her own in such a situation.

"So you want me to go in with you and pretend to be your boyfriend then?" I asked.

"Sort of, yeah. You'll put off any creeps who might try to hit on me. You might find something worth buying too."

Shortly, Tammy parked the car down a back street and we walked up to the sex-shop, tucked away behind a noisy car-garage, well away from the nice family-friendly area of town. We entered, and I was surprised that the large store was tidy, well-lit and clean. A guy at the counter nodded hello from behind his paper, whilst two guys browsing seperately through magazines hardly paid any attention to us. A TV in the corner played a video, on which a Japanese woman was getting cummed on by a dozen guys, one at a time. The sound was turned down and a radio next to the till blaring out commentary on a football game.

"Here's the toys," Tammy said, "This is what I want."

She boldly walked to the corner that held shelves stacked with dildos, boxed inflatable dolls, leather suits, whips and a shitload of other things. I decided to browse through a few magazines, feeling strangely liberated and unashamed with Tammy here with me. After just scanning a few covers, however, the mags began to give me a hard-on, so I went over to Tammy who was browsing through a load of dildos.

"Anything you fancy?" I asked, barely unable to contain my grin, knowing that no matter how respectable and normal we tried to act, it didn't change the fact that I was helping her choose plastic cocks to shove up her cunt. And my sister's, I suppose.

"Oh there all so nice," Tammy grinned, giggling a little, "Seriously though, I need a strap-on. Ours is broke."

I nodded, trying to keep away images of Tammy wearing a strap-on dildo, naked, greasing it up, feeding it into my sister's cunt as she rubbed her...

"I might get these two," Tammy continued, pulling me out of my lewd fantasy. She held a box in each hand, the first containing an 8" white-strap-on, the other a strange looking pink dildo that was curved in on itself so it looked like a flattened 'C'.

"What's that one," I asked, pointing to the curved one, "It looks fucking odd.'

"It's a double-dildo," Tammy explained, knowledgebly, "It's made of flexible plastic. You can straighten it and feed each end into a woman and keep two happy with one dildo at the same time, or a woman on her own can bend it like it is now and feed on end up her cunt and the other into her arse."

"Well I'll be damned, I never knew that," I smirked. Tammy playfully punched me on the shoulder, telling me that I 'like a giggling schoolboy in a sex-education lesson', even though she herself was sniggering.

"I need a vibrator too," Tammy added, "Here, my hands are full. Grab that one will you."

She nodded her head at a selection on the shelf.

"This one?" I asked, reaching up to a box which contained (according to the bright packaging) a "vibrating, silver torpedo of pleasure!"

"Yeah. How long is it? Does it say?"

"Er..it say's 'seven inches'"

"Any bigger ones?"

"The one next to it is eight. It looks the same make and model, just er...bigger."

"That'll do. Grab it for us Paul. Fetch some of that too," she added before heading to the counter, pointing towards a tube of KY-Jelly. I took some and followed her as she made the purchase, paying with cash for the two dildos and the lubricant.

With the goods in a plain plastic bag, we left the shop and headed back to the car.

At the house, we packed the food away into the cupboards and fridge, then went to the lounge. Gemma was out, and would be for most of the day, and as I sat on the sofa I watched with some amusement as Tammy emptied the bag from the sex shop onto the coffee table and looked at her purchases like an excitable kid on Christmas day.

"Nice selection I have here," she smiled, "Did you not get anything?"

"No," I replied, shrugging, "Nothing I fancied. Not within my price range anyway, it's amazing how fucking pricey some porn is."

"Yeah. Not to worry."

Tammy then took the box containing the vibrator and opened it up, removing the shiny, chrome cock from it's packaging and checking that it came with batteries ("They never used to," she informed me solemly, "We used to forget to buy some and have to nick 'em from the TV remote")

As she checked it, turning it on briefly, then off before admiring her reflection in it's shiny surface, I tried to think of something to say to break the silence that hung in the air.

"Is that er...for you?" I asked, "Or for Gemma? Or both?"

"For both of us," she said, "We often use strap-ons but freehand dildos are often fine too. Or fists."

"Fists?"

"Yeah," confirmed Tammy, "You know, using the fist?" She clenched on of her hands to demostrate, "Just do that, clench, as if you're about to punch someone, then slide it up."

"Into the cunt?" I asked, enjoying such a candid talk.

"That's right. Or the arse."

"The arse?"

"Yeah. As long as you use a load of lubrication - like that KY-Jelly we got - it's not that hard to get your whole fist up a bum. Your sister loves it!"

I smiled and nodded, Tammy looking as if she was wondering if she'd overstepped the mark in being so forthcoming. I wasn't in anyway bothered, and I made it clear by asking "Do you like getting arse-fisted too?"

"Sure," Tammy nodded, "Not as much as in the cunt. Your sister's a bit of an anal-fan. Dildos, fists, fingers, whatever. If it'll fit up her arse she'll shove it up there. Or get me to."

Of course, many, many images were going through my mind at this moment, my prick hardening in my pants.

A silence followed, which was broken when Tammy tried the vibrator again, sniggering foolishly as she placed it on the coffee table and watched it judder and buzz it's way to the edge where she caught it as it fell.

"We've actually got some porn here," Tammy admitted, "Some videos anyway. Me and Gemma thought they might be exciting, but really they're not as good as doing it for real. It's all lesbian stuff, of course, but I know you blokes rather enjoy that."

She beamed a cheeky grin, which I returned.

"Can I borrow them then?"

"Sure. They're around somewhere."

"I haven't got a video in my room though," I added, "Have you got any mags?"

"Why go to your room?" Tammy asked, puzzled, "You don't have to go there to jack-off to lesbo porn my dear! Just do it here."

"Yeah?" I asked.

"Why not? Hell, I'll join you if you want. I wanna try these things out."

"The vibrators?"

"Yeah. Actually, what we could do...if you want...is is just watch each other jerk off. You whack off and I'll use my vibro and get off on watching each other. As you probably know, like your sister I'm not, like, a pure lesbian. Nothing wrong with men and real cocks. I'd really like to watch you."

"Okay," was the only polite response I could think of. It sounded a bit freaky, and I said so.

"Don't worry about your sister," Tammy insisted, "I've had a few one-night-stands with guys since me and Gemma started going out. So has she. Your sister often fucks a bisexual male friend, for a bit of fun, occasionally, or at least she did until he moved away. With us it's only cheating on each other if we do it with another woman...and even then only if we don't let the other one in on the fun!"

What little anxiety I felt was over-ridden by the hardness of my cock.

"Let's go for it then," I stated. Tammy stood and began to take off her jeans, and I did likewise, both of us casually admiring each other's naked bodies once we'd stripped. Tammy looked so fucking horny, tanned, dark and alluring. Her cunt was perfectly shaven, as bald as child's.

"Want to put a porn movie on then?" she asked me.

"Don't really need it," I shrugged, "If you're naked in front of me that's all the viewing pleasure I'll require! You look...fantastic."

"Thanks. So do you. If I ever develop a preference for men, I'll dump Gemma and shack up with you!"

We laughed, then got down to business. I knelt on the floor and Tammy sat opposite me, spreading her legs and flicking on the vibrator, She rubbed it along her clit, along her lips, then slowly fed it into her wet, glistening slit. Jacking off my prick, I watched her, fascinated and aroused, pleased that Tammy was enjoying watching me as much as I enjoyed watching her. We didn't make much eye-contact - there was no need - as we frigged ourselves off in front of each other.

I guess it was inevitable that we should frig each other, so I opted to air the idea, which Tammy agreed to eagerly.

My sister's lover lay on her back, spreading her legs and inviting me to kneel next to her, my eight-inch prick hovering menacingly over her chest. I took the vibrator and began to slide it into her cunt whilst Tammy reached up and gripped my prick. She masturbated me with considerable skill, and I frigged her cunt with the buzzing chrome-cock using the same technique as I'd seen her use on herself a moment ago.

I was wondering whether this was going to lead to when, after ten-minutes, Tammy answered my unspoken question.

"Hey Paul, wanna fuck?" she asked.

"Are you sure?" I responded, making it clear that I wanted to, but was just concerned that she was acting on an impulse she'd regret.

"Totally! Come on, we've come this far. Like I said, Gemma won't mind. Hell, I'll tell her, with pride. She'll be pleased for me, and for you."

"Shall I get some condoms? I've got some in my room."

"Nah, don't worry about that. I'm on the pill. I know I don't really need too, be I just take it out of habit to avoid PMT and stuff. Same with your sister actually. Anyway, come on, I need cock!"

Tammy got up onto the sofa, sitting on the edge and laying back with her legs spread. My sexual experiences were not vast, but I had enough practise to be confident enough to get down between Tammy's legs and start licking out her cunt. I frigged her clit as I lapped at her juicy lips, sliding my tongue up there eventually and eating her out hungrily, her bald pubis smooth against my face. Tammy was considerably excited, holding my head in her hands and urging me on. With my prick raging stiff, I knelt up and fed it up her cunt, the moist cunt clinging wetly to my cock as I began to fuck her.

We lost ourselves quickly, panting and grunting animalistically as we screwed on the sofa, myself groping Tammy's firm little titties whilst she held my shoulders and humped her arse off the sofa to meet my thrusts.

"Oh shit, I'm gonna cum," I announced eventually, "Shit! Oh God!"

"Fuck me Paul!" Tammy cried, "Fuck me hard! YEAH"

Increasing the pace of my thrusts harder, I began to fire my seed up into Tammy, her cunt feeling so hot and tight as I unloaded a hefty-wad of thick sperm up there. Once I'd finished, I slowed down and fell forward, me and Tammy kissing hard as my cock softened inside her spermy cunt.

When I pulled out, we both smiled at each other and kissed once more, Tammy once again telling me that my sister wouldn't mind this, and generally making it clear to each other that there was no guilt involved, that neither of us regretted it.

We dressed and made lunch, watching TV for a while until I felt horny again. Tamym was only to happy to accept my suggestion of going to my room, but she did insist that we go to hers.

Gemma and Tammy's room was large and bright, floor-to-ceiling windows taking up most of one side, blinds letting in the sunlight from the back garden. The walls and carpet were light beige, the furniture white with brass fittings, the white-oak bed fitted with cream sheets. Hopping onto the same bed she fucked my sister, Tammy invited me up onto it. We engaged in oral for a while, a long 69 to get us perked up. Then I cunt-fucked Tammy in the missionary position, our nude bodies hot and pressed against each other. Then Tammy went on top, riding my prick with her tight cunt like the proverbial kangaroo on a trampoline! I had to ask her to dismount lest I cum sooner than I wanted too. I fucked her with me on top to finish off, shooting my sperm up into her cunt as we kissed hard. A nap followed, then a shared shower before dressing and getting the dinner on for when my sister came home.

As expected, Tammy told Gemma that evening whilst I happened to be in the bath. I wandered out in a T-shirt and boxer-shorts to find the two of them cuddled up on the sofa. It was a hot night for September, the windows open but the room temperature still in the 70's. Curled up at one end of the sofa, Tammy wore a long black T-shirt that reached half-way down her thighs - I guessed she may, or may not, have a pair of panties on too - whilst Gemma lay up against her lover, in just a black bra and black panties, her legs stretched out across the black leather sofa.

"Hey stud," my sister called, "Been takin' a cold shower?"

"Tammy told you eh?" I shrugged, not too sure how to approach this, but quickly realised Tammy was right - it'd been no bother to my sister at all.

"I don't know who was hornier," Tammy began, "Me or your brother. We were both dying for a frig and one thing lead to another...hell, I'm not explaining this Gemma! You'd do the same thing if I had a brother."

"You little rascals," Gemma smiled, "Sneakily fucking whilst I'm at work. Heh! Seriously, I don't mind, I'm sure Tammy told you we don't have a totally monogamous relationship."

"Except when it comes to women," I observed, sitting on the armchair."

"Yeah," confirmed Gemma, "It's two-timing if either of us shag another woman, unless the other can join in."

Tammy giggled, the atmosphere in the room being totally relaxed and pleasant. We didn't have any secrets really. Tammy could have been sitting their nude, or I could announce I was off to my room for a wank, and it wouldn't cause a stir. I helped myself to a glass of the red wine sitting on the coffee table and drank it down slowly as we all watched telly. After a programme finished at about ten, my female housemates got up and announced they were going to bed.

"I'll see you in the morning then dear," Tammy said, and as she had started doing a few nights ago, leaned down to kiss me goodnight, but unlike previous nights she kissed me for a few seconds on the lips, her wet little tongue slipping into my mouth. She stood up and sauntered away, sexily. My eyes were fixed on her lovely legs until, unexpectedly, Gemma also leaned down to kiss me. She too gave me a rather lingering smooch then walked off, probably aware that I was look at her asscheeks move erotically in the tight, skimpy panties she wore.

Soon, the pair of them were out the living room and I was alone, my cock solid in my pants. I was going to have a wank once I was sure the two of them were settled down. Then I realised it wouldn't have been a big deal if either had come in and caught me so I got down to it straight away.

I opened the cabinet between the wide-screen TV and found the porn videos clearly on display next to more innocent titles. I selected one called "Anal On The Isle Of Lesbos", stuck it on the VCR and sat back to jerk off.

Quarter-of-an-hour later, I'd finished, cleaned up and went to bed.

When I'd walked past the door to Gemma and Tammy's room, I heard rather passionate noises coming from there. In my room, I stripped and put an ear to the wall that joined with my sister's room. I could hear, dull but audible, the sounds of both women panting and moaning in pleasure. My sister, it seemed, was the one on the receiving end of some sort of enjoyable activity, her cries of joy loudest. Tammy was saying something too, something passionate but not clear to my ears.

Highly aroused once more, I turned off the light and clambered into my bed. I began to jack off, but was so tired that I fell asleep.

After waking in the darkness, I wondered whether it'd been minutes or hours since I'd nodded off. Then I noticed the faint light at the window and saw the alarm clock reading 06:43. Saturday morning I thought; a day of relaxation. Perhaps another little fuck with Tammy.

I was ready to jerk off, but I need a piss first so I went, tip-toeing around to avoid waking the two ladies next door to my room.

Back in bed, I lay back and stroked my stiff cock that lay throbbing across my stomach. As always when I'd fallen asleep the night before half-way through masturbation, my arousal levels were high and my cock ultra-stiff. Then I heard movement outside, then a soft knock at my door. Tammy opened it and entered, flicking on the light and closing the door. She was wearing nothing but a pair of white knickers and a big grin.

"Hiya Paul," she said in barely above a whisper, "I thought I heard you awake."

"Yeah, I often wake up early when I don't need to," I replied, sitting up, my cock getting harder as Tammy approached the bed.

"I'm horny," Tammy announced, whipping off her panties and flinging them aside and hopping onto the double bed, "Fancy a fuck?"

"Wouldn't say no," I grinned, and tugged she duvet aside and kicked it to the floor. Tammy gripped my steel-hard, fat cock and leant down, running her tongue over the swollen head before sucking down on it. She deep-throated me jolly well for a lesbian - bisexual, whatever - before mounting me, sinking her bald slit down onto my prick and both of us sighing with mutual pleasure. I reached up and stroked her tits, pinching her hard nipples lightly as she rocked to and fro on my cock.

"You were a bit noisy last night," I said after a few minutes of quiet fucking.

"Shit, did we keep you awake?" Tammy asked, concerned for me getting enough peace at night, not at being heard screwing my sister.

"No, not at all. The walls are fairly thick."

"Aaah," grinned Tammy, "So you must have listened out for us eh?"

"Well...yeah...I admit it. It was kinda noisy though, it sounded fun."

"It was! Me and Gemma fucked in a rather frenzied manner, probably because I was still hot after our activities in the day."

"Shall we do this again today? Fucking I mean?"

"Sure. I don't have any plans. Christ, I'm horny. I wanna fuck all the time these days, even before you turned up! And Gemma was fucking horny too last night."

"Whaddya get up too?" I asked, still being ridden gently by Tammy.

"All sorts," she said lustfully from above, "We played with the new strap-on, with the double-dildo and had a good 69...the usual! Your sister is just so hot, so sexy! We fisted each other's butts too; mine's still aching a bit. In a nice, pleasant kind of ache, y'know?"

I didn't really 'know', but this talk was making me even more aroused. Not satisfied with Tammy's pace, I invited her to dismount and lay back so that I could mount her. I fucked her hard as we lay clutching each other and panting into each other's ears, our bodies humping and grinding against each other.

Soon, Tammy's body tensed beneath me, and she lightly bit the flesh of my shoulder, muffling her cries of pleasure as she was hit by an orgasm. My pace increased further and my climax approached, hitting me hard.

"Oh fuck, yeah, I'm cumming," I stammered, firing cum deep into Tammy's wet cunt.

I continued humping until both our climaxes were fully finished, and we lay in each other's arms with the dawn light beginning to pierce through the musky room for almost fifteen-minutes.

We finally broke up, sharing a shower as we had done yesterday, Tammy opting to head back to bed with the still slumbering Gemma, whilst I tugged on a pair of shorts and went to watch early morning telly.

Lunchtime, and the temperature that day was unseasonably warm at lunchtime. I was slouched across the sofa in just my boxer shorts, regular excercise at the gym for the last few years having given me a lean, athletic body which - whilst I didn't arrogantly judge it to be perfect - I was at least proud of. I was drinking a can of Pepsi and feeling faintly aroused as I watched MTV, Kylie Minogue wiggling her arse at the camera as she sang some song or other.

Tammy was sat in the armchair nearby, wearing a tight half-T-shirt that showed off her slim stomach, and also a pair of white denim cut-offs. She was sat sideways, her lovely smooth legs swung over an arm of the chair, the toes of her bare feet occasionally flexing as she flicked through a magazine and hummed quietly to the song on the telly.

Gemma had been stacking the plates from our recent late breakfast into the dishwasher before sauntering into the lounge area. The drapes were pulled shut so there was no need for modesty in the privacy of the room, meaning Gemma was rather scantily clad in a pair of white shorts and a blue bikini top.

"It is so fucking hot in here," she observed, "The heating is off isn't it?"

"Yeah, I checked," I told her.

"I can't believe it's September," Tammy commented, "It shouldn't be this hot."

"Make the most of it," Gemma told her, sitting down on the floor in front of the sofa I was laying on, "It'll be winter soon."

"Do you want to sit up here," I asked my sister.

"Nah, I'm fine down here, as long as I can have some of your drink."

I handed her the half-empty can of Pepsi which Gemma noisily guzzled from before handing it back. The video on the TV continued to play, prompting a discussion of Kylie Minogue's arse, the Australian woman's derriere being wiggle half-bare rather frequently on the screen.

"Definately a nice arse," Tammy was commenting.

"But her tits aren't anything special," was my two-cents worth.

"A great bum though," Gemma insisted.

"Oh yeah," I agreed, "That is a fucking nice bum, no doubt about it."

"I heard," began Tammy, "That the choreographer figured that Kylie couldn't dance, so merely asked her to wiggle her arse a lot during the music video."

"It wouldn't surprise me," Gemma said, "After all, most people would rather look at her bum than just see her attempt to dance, even if she was good at it."

"Madonna has a great arse," Tammy said, "Or had a great arse. It doesn't get shown off as much these days now she's gone all mature, but when she was whirling around in her music vids with little on, she had a fucking nice bum."

"What about Anna Kournakova, or whatever her name is?" I added, "She's fucking hot!"

"Totally," agreed Tammy, "Nice face, nice tits...fantastic bum!"

"Fantastic bum," I intoned, nodding.

"Not as nice as mine though," Gemma chirped.

"Nowhere near as nice as yours," I reassured her, then began stroking my hand through her hair as she remained cross-legged on the floor in front of me.

"Or mine," Tammy interjected.

"Yes yes," I sighed with mock impatience, "You've got a nice arse too. All the girls in this room have fucking great arses! Jeez you're self-consciouss."

The two ladies sniggered.

The Kylie Minogue video ended and on came some Brazilian song. Fuck knows what it was, but it featured lots of shots of Latin ladies in bikinis and thongs, lots of butts which held us three in rapt silence, it being unsaid how aroused we all were at the parade of women's arses on TV.

"Fucking hell I'm horny," Tammy announced once it'd ended.

"Me too," I added, my cock indeed stiff in my Simpson boxer shorts but not feeling the need to hide it, "Aw fuck, a Phill Collins video is coming on! How unarousing is that?! I might watch that lesbian movie later, the one I started viewing the other night."

"That 'Anal On The Isle Of Lesbos' one?" Gemma asked, "Yeah, the tapes on top of the video."

"Hey Gemma, you horny?" Tammy asked.

"As always. Why? Wanna nip to bed for a while?"

"Why bother going to bed?" Tammy grinned, clearly planning something, "Fancy a live show Paul?"

"Huh?"

"Well," shrugged Tammy, tossing her magazine to the floor and getting up out of the chair, "No point in you watching women fuck each other on telly when there'll be two doing just that in the same house. It seems silly! C'mon Gemma, let's get it on. You're brother can watch us."

"Okay," Gemma smiled, looking at me and seeing that - whilst a little anxious, as she was - I wasn't objecting to the idea in anyway.

"Right," Tammy began, moving the coffee table to one side, "Sit up Paul, whip the old man out and prepare for a great show!"

I sat up and, on seeing Tammy begin to quickly undress, went ahead and tugged off my shorts. My cock was rock hard and I stroked it a little self-conscioussly - but highly aroused - as I saw the two women before me, now naked. Tammy was still a delight to behold in the nude, but I was fascinated at my sister's naked body; her cunt was adorned with a neatly trimmed amount of hair, the same golden blonde as her head-hair. Her tits were fairly large and as mouthwateringly shapely and firm looking as I thought, her skin clean and smooth.

Tammy had suggested this idea but it was Gemma who got things underway, kneeling on the floor and pulling her lover down to her, kissing Tammy hard on the lips as they groped each other's tits. Eventually, Tammy moved down and sucked on Gemma's stiff nipples, frigging my sister's cunt before moving down further, Gemma laying back now and having her cunt eaten out. I was jacking off steadily now, infinitely aroused. Women in porn movies who got it on with each other were, I'm assuming, not really lesbians or even bisexual. They were just doing it for cash, and probably didn't enjoy it much most of the time. This, however, was utterly genuine, and soon it appeared as if the two lustful women before me had forgotten I was there.

Tammy now lay back whilst my sister sucked on her nipples in turn before going down to lap hungrily at her girlfriend's dripping cunt. I spotted the silver vibrator from earlier sitting nearby, and I picked it up.

"Here sis," I called, stroking my cock with one hand and offering the battery-powerered phallus to Gemma with the other.

"Cheers Paul," she said, taking the vibrator and flashing me a cheeky grin, cunt juice slathered round her mouth, saliva and more cunt-fluid hanging from her chin in a gooey string.

Gemma turned and flicked the object on, buzzing the end round Tammy's clit whilst pushing two fingers into her cunt.

Soon, she was pushing the whole thing into Tammy, sliding it in and out of that tight cunt whilst Tammy rubbed her own tits and moaned in genuine pleasure.

Another switch followed, my sister now on her back whilst Tammy got to work on her cunt, first employing the vibrator to good affect, and then putting it aside and just getting down onto her knees and elbows, hungrily eating out Gemma. Whilst pushing her tongue up into her lover's cunt, Tammy was pushing one of her juice-slathered fingers up into my sister's anus, up to the knuckle and causing the young lady some rather heated exitement.

I stood and moved to the armchair, behind Tammy, jacking off as I looked at her spread arse that was thrust towards me, her firm buttocks spread, her rosy arsehole twitching, below which hung her hot, glistening cunt. It was a fair assumption that I would be able to join in this little coupling to make it a threesome - such an invitation had clearly been made, if not spoken, in that both women must have realised what effect it'd have on me.

I got up and knelt behind Tammy and rubbed my swollen cock head up and down against her moist cunt lips, then plunged in. Tammy shuddered with delight and humped her cunt back onto me whilst eating out my sister, who flashed a grin at me, making it clear I was more than welcome to throw myself into the mix.

Holding onto Tammy's hips, I began fucking her cunt hard and fast, my meat sliding to and fro inside her gripping slit. Only strong willpower held my orgasm back.

"Time to swap over," Tammy announced shortly, and I pulled out of her whilst the two women switched places. I'd realised Tammy had wanted me to fuck my sister when she'd boasted of how 'hot' Gemma was earlier, and it was inevitable, since the suggestion of this 'live show' for my behalf that it'd come to this. Excitement at the incestuous act moments away gripped me, my cock standing high and hard, as Tammy lay back and Gemma got on her hands and knees between her legs. She began to lick Tammy's cunt but was clearly concentrating on my actions, Gemma's body shivering with pleasure as she felt my hard cock nudge against her cunt. I guided myself into my sister, her cunt very wet but still hot and tight, clenching my shaft as I began to fuck her hard. Spurred on by this stimulation, Gemma ate out Tammy's cunt with great enthusiasm, causing the dark haired slut to hold my sister's head in her hands and push it into her groin.

"Oh fuck," she was grunting, "oh Gemma, lick me out! Lick my cunt, yeah!"

I humped Gemma steadily, turned on by the sight of the women continuing to get it on before me. My orgasm began to raise it's head, but I held it back, grateful moments later when, on increasing my speed once again, I made my sister climax.

"Oh Paul!" she cried, her voice muffled as her head was still pressed between Tammy's legs, "Oh shit fuck me I'm cumming, oh! Oh! Fuck me!"

I slammed into her cunt, feeling her shake with joy under my humping pelvis. Her orgasm died away, after which she resumed eating out Tammy, moving her head down a little to tongue her girlfriend's bumhole, Tammy meanwhilst propping herself up on her elbows. Her long black hair clung to her sweaty face, our bodies all beginning to glisten in the hot room which filled with musky smell of hot bodies.

"Is your sister as good a fuck as I told you she was?" Tammy purred.

"Damn right," I confirmed.

"Well, don't forget," continued Tammy, "There's more than one hole in front of you there. Remember how much I told you your randy big sister likes it up the bum?"

Gemma raised her head long enough to instruct me to "Fuck my arse!" before resuming performing oral on Tammy. I'd once been out with a girl who'd let me bum-fuck her a few times and I'd liked it a lot. Like a lot of men - and indeed, some women - anal sex was not just exciting because of the physical feeling, but also the kinky nature of it. Right now, I was almost shaking with erotic anticipation at the taboos wrapped up in the upcoming act - incest, sodomy, mixed in with a bisexual threesome! Keeping my cool, I eased out Gemma's cunt and I slid my forefinger into her anus, finding it suitably loosened from Tammy's tongue-related attention earlier. I thus took my cock in hand, guided the head up to the slightly yawning hole and began to enter, Gemma tensing as he arsehole parted and allowed in my cock. Soon, she relaxed, breathing hard as she just lay her head to one side on Tammy's stomach, releasing a long, pent up moan of pleasure as I fed my throbbing rod up into her twitching anus. I was soon lodged in to the hilt, the rectal passage hot and tight, the membranous walls of her anal-canal feeling soft and slick against my stiff cock, her sphincter nipping my shaft. I began to fuck her, slowly at first then quicker, Gemma getting back to eating out Tammy's cunt as she was buggered.

For ten full minutes I arse-fucked my sister, in utter heaven, until I was compelled to pull out on the brink of orgasm. My dick was still proudly hard, Gemma's shitter gaping before me and leaking brownish pre-cum from it's reddened edges. My sister got up and sat on the sofa, getting her breath back. Tammy still lay on her back with her legs parted, so I mounted her and easily slid my thick dick up into her wet cunt, the woman enthusiastically wrapping her legs round my waist and gripping my arse to pull my fully into her. We fucked quickly and without grace, snogging passionately whilst Gemma watched and frigged herself from the sofa.

Still in-tact and hard, I pulled myself off Tammy and shuffled over to my sister, who sat back and welcomed me with open arms. I sank my cock up into her cunt and kissed her, moving down to lick her tits whilst I fucked her cunt. Tammy soon joined us, sticking her tongue down Gemma's throat. My orgasm finally arose and I almost fainted with pleasure as I was wracked with a powerful climax. My cock shot out squirt after squirt of thick sperm into Gemma's cunt, my sister taking her lips from Tammy's and planting them on mine, us two fuck-hungry siblings sucking in each other's sighs of pleasure as I continued to shoot my wad up into her womb.

Finally finished, I pulled out and dragged myself onto the sofa next to Gemma, who lay sweaty and out of breath between her girlfriend and her brother. We all left it unspoken as to how much fun it'd been, and how things would be even more fun in the future. The television was still tuned to MTV, and we lay watching a few songs before my sister took my semi-stiff cock and began stroking it back to stiffness.

"Let's go to our room," she said, and stood up. Me and Tammy did likewise and followed Gemma into her room.

Clambering onto the bed, we all engaged in a foreplay free-for-all, kissing, stroking, fondling and frigging each other in a random pattern, my dick soon rock hard and the girl's moist and ready for fucking.

The girls lay me back and tended to me together, taking turns to kiss my mouth and suck my cock, at one point both moving down to my groin. Gemma would suck the head of my cock whilst Tammy lapped at the shaft, then they'd swap jobs.

"Want another fucking from your little brother?" I asked Gemma when I eventually sat up.

"Absolutely!" she said, enthusiastically, "Fuck me up the arse again! You buggered me beautifully earlier and I want you to cum up there! Tammy?"

"Yes my dear?"

"Let's 69! I'll go on top so my brother can access my shitter!"

"Sure thing," Tammy agreed. She lay down on the bed, feet pointing towards the headboard, and the graceful manner in which my sister mounted Tammy, inverted in the 69 position, suggested it was a position they adopted a lot.

They wasted no time in commencing licking each other's cunts out, and I knelt behind my sister's arse and watched whilst jacking off as Tammy buried her chomping mouth into my sister's furry, slick cunt. I got down and lapped at Gemma's anus, both her holes now being tended to by busy tongues, before I got up and eased the head of my dick to her dilated anus. Slowly but surely, I eased into her bum, sliding my cock right up into the depths of her rectum before commencing a steady fucking motion. Gemma clearly got off on this a lot, bucking her arse against my dick and grinding her cunt onto Tammy's face, all the while lapping at the cunt she had before her.

The tight heat of her arse was exquisite and I fucked it whilst just admiring the view, the sight of my prick sliding back and forth in my sister's arsehole whilst she 69'd Tammy. My sister hit another climax eventually, raising her head from between Tammy's spread legs and crying out over my shoulder "Oh fuck my arse Paul! Fuck me! Fuck! YEAH!" with her hair flung messily everywhere, her face sweaty, a string of saliva connecting the corner of her open mouth with Tammy's quivering, juice-slathered inner thighs.

I hadn't fucked Tammy's arse yet, so I shortly decided to put that right by easing out of Gemma. Clearly with the same ideas, the two girls quickly switched over, my sister now beneath her inverted lover's body. Whilst my sister ate out Tammy's cunt from beneath, I bent down and licked my sister's girlfriend's anus, tongueing and fingering it, briefly leaving it to move down and join my sister in eating out the bald cunt, our tongues sliding together in the heat of Tammy's slit. My prick was throbbing with anticipation, and unable to wait any longer, I knelt up and placed my cock to Tammy's arsehole and applied the pressure. With a beautiful elegance, her anus soon bloomed open and allowed me in, Tammy shivering with electric pleasure as my dick journeyed up into her shit-canal. I fucked her hard as I'd done so several times to her cunt, gripping her shoulders as I did so whilst Tammy occasionally rose her head from Gemma's groin to urge me on with obscenties that'd shock a soldier! She hit a climax after ten-minutes, her arsehole spasming round the hilt of my dick.

As fantastic as Tammy's arse was, I wanted to cum in my sister again, or more specifically, in her bum. I withdrew and asked the two ladies to swap over once more, which they did, making me feel like a porn director as I orchestrated the positions of these horny ladies.

Tammy was once again down below in the 69, my sister on top, and I wasted no time in spearing her arse with my rampant cock. I fucked her hard and fast, animal lust overtaking me and finally my sperm flowed again. Throbbing as it spewed forth cum, my cock was lodged right up my sister's shitter, flooding her bowels with white foaming liquid, and during my orgasm from below Tammy took her mouth from Gemma's cunt and sucked on my balls which banged up against my sister's groin whilst I came. My pelvic thrusts soon slowed down and halted, the last drips of my sperm leaking into Gemma's arsehole whilst Tammy took my whole scrotum into her mouth and pushed my balls around with her tongue, after which I pulled out. The two women broke up and, with big grins on our faces, we got our breath back. All three of us were already planning the next adventure...

We later got up and dressed; or at least, put some underwear on. I double-checked with my sister and Gemma that I wasn't intruding on anything, that somehow I wasn't spoiling their quiet lives. I was really just seeking reassurance, which I received when the two ladies told be not to be so silly, that they'd always accepted that they were together as a couple in terms of a long-term relationship, but that when it came to sex, it was 'the more the merrier' and that my presence would be most welcome. Satisified with this, we set about making lunch, all of us buzzing with excitement and feeling on top of the world.

We had a big meal at the table, still sitting around in underwear, my sister in fact topless with her lovely boobs on display.

Later, we watched telly, having already found favourite spots on the sofa; me at the far end, Gemma curled up against me and Tammy leaning against Gemma's side with her legs stretched out.

Horniness tugged at us when a movie we'd been watching eventually finished, and we fucked there in the lounge. The novelty of it all meant we switched and changed positions a lot, trying out new things, sometimes directing each other in an organized way, other times just doing whatever we wanted spontaneously. I eventually fired my seed into Tammy's cunt whilst sucking on my sister's tits.

Chores were lined up for the rest of the afternoon; grocery shopping then some house cleaning. We all had a long walk in the park at sunset, killing time until bedtime! Tammy and Gemma said they it'd be a bit disruptive if I spent every night in their bed - something I agreed with - but I was more than welcome to join them for the night a few times a week, including this one. We scampered off, horny and excited, to the master bedroom at nine and didn't finish fucking until after midnight!

In the morning, Gemma had a great urge to be double-fucked. Fetching the strap-on dildo, she had Tammy lie back and fit it to her waist, my sister then mounting her and sinking her cunt onto the plastic cock. I then greased up Gemma's anus with KY-Jelly and buggered her, my sister bucking and thrashing with climactic joy as she was fucked hard in both holes.

Naturally, Tammy had a turn next and enjoyed it just as much, hitting a powerful orgasm just before I did, my sperm flooding her rectum as I reached round and grabbed at her tits, my sister meanwhile fucking the strap-on upwards into her lover's cunt.

Tammy introduced me to fist-fucking that Sunday afternoon, and took delight in fisting Gemma and then Tammy in the cunt. With plenty of lubricant, I was able to then fist both women in the arse, finding it so horny when I had my whole hand up my sister's tight rectum that I shot my load, my cock at the time being down Tammy's throat. She guzzled down every drop. Gemma hadn't had a taste of cum for years and insisted on getting a drink of later, so when I was later fucking Tammy's cunt and approaching orgasm, I pulled out and fucked my sister in the mouth. Frigging her clit, Gemma sucked deeply on my dick and didn't spill a drop when my thick cum exploded down her gullet. She hit a climax as she drank, swearing it was 'almost as nice tasting as Tammy's cunt juice.'

The weeks went by. College was going well, Tammy and Gemma pretty much acted as they always had done, getting on with their respective jobs and being in love with each other - albeit inviting me to join in most of their regular sex sessions.

Sometimes I fucked them on their own. One might be tired and off for an early night, or working late or just out for the evening, leaving the other with me for a good session. I didn't have a preference for either lady; Tammy was very experienced in sex, her body lean, supple and dark, her appetite for fucking in all it's forms unquenchable. Me and Gemma obviously liked the incestuous nature of our relationship, and on a more superficial level, I liked her big tits and bright young face, which - probably because she was my sister - always seemed charmingly innocent, even when contorted with pleasure and/or having sperm sprayed over it!

Tammy had been right about my sister being an anal addict - Gemma wanted it up the arse nearly all the time, which was a desire I was more than happy and able to satisfy.

Tammy enjoyed anal too but primarily liked vaginal sex, and me and my sister made sure Tammy's cunt was as well tended too as she requested.

Sitting in the student bar at college, I was flicking through a newspaper whilst sipping a beer. It was lunchtime and I didn't want to get drunk, so I stuck to a single bottle.

The place was fairly busy, my fellow students mostly congregating around the jukebox and talking loudly, whilst I remained on my own until, as arranged, a girl in my lecture group who'd insisted on meeting me after class entered and came over.

Her name was Helen and she'd obviously had a crush on me for a while, chatting to me at every opportunity. A black girl a year older than me, she was fairly pretty with long hair down to her waist and had a pleasant nature. Short at barely five-foot, she was slightly plump with a round face, heavy tits that looked extra big on a girl of her stature, and a chubby arse that, as usual, was currently squeezed into skin-tight biker shorts. She'd fucked a few guys in the class, so the rumours went, but few people at college were narrow-minded enough to regard her as a slag. If she wanted to fuck a lot of blokes, why the hell not? And whilst I didn't regard her as an object of utter desire, she was quite nice and I got a stiffy when I caught glimpses of her round arse.

"Hi Paul," she called as she pulled up alongside me at the table, "You alright?"

"Yeah fine Helen," I replied, "You want a drink?"

"A beer, yeah. Here, I'll go. Want a refill?"

"No thanks."

Helen went up to the bar and got her drink, my eyes fixed on her arse, the panty-line visible through the light grey material of her shorts. Soon, she returned and sat close to me as we talked about college, music and various crap.

I wasn't surprised when Helen invited me up to her place at the college halls, but I was still glad, the girl's flirtatious nature, which had increased after a couple of drinks, increasing the prospect of sex. No matter how much fucking I did at home with Tammy and my sister, I was still horny for other girls, and my dick was faintly stiffening as I followed Helen out the bar.

Fifteen-minutes later we were in her room, a large room with a bed, study desk and en-suite bathroom on the eighth floor of a big accomodation building at the edge of campus. After Helen put some music on, I sat next to her on the bed and just started kissing her, knowing that her crush on me meant this was what she wanted. She stuck her tongue down my throat and grabbed my crotch, my cock hard in my jeans as I responded by stroking her heavy tits.

Soon, we parted and undressed, my dick throbbing hard as I tossed my clothes aside. Helen, I must admit, was a pretty sexy little thing, even if she was a few pounds over weight. Her tits were big and round, her arse fairly firm looking despite it's chubbiness, and not having fucked a colored woman before I was feeling extra aroused by her dark-coffee brown skin as she now got onto her single bed, naked, whilst I slid on a condom.

"Come and fuck me Paul," she invited me with a grin, and I quickly mounted her, Helen obviously not giving a shit about foreplay. I sank my hefty prick into her cunt and began shafting her, her body warm and soft beneath me. I wasn't used to fucking with a rubber, but it still felt nice banging this girl who grunted lustfully as she was given a good shafting.

I kissed her on the neck and shoulders as I fucked her, feeling her big breasts pushing against my chest. Helen later sensed that I was tiring and invited me to dismount. Once I'd done so, I lay back and Helen clambered astride me, grinning joyfully as she impaled her slit onto my stiff prick and rode me. Her pace was impressive and her big titties swung up and down as she bounced on my cock whilst I held her waist.

"Shit, I'm cumming!" I eventually announced.

"Fuck me," Helen urged me, riding quicker whilst I fucked my arse up off the bed.

My orgasm was long and powerful, my sperm squirting out in prolonged bursts as I shuddered with pleasure, Helen bending down to kiss me on the mouth during my climax.

After a moment, she dismounted, my rubber-sheathed cock sliding out from her moist cunt, and with obvious practice she slid the condom off my wilting cock and tossed it into a nearby bin before draping herself across me. Knowing that this girl wouldn't really expect a long-term commitment, with romantic nights out and stuff like that, merely a regular fuck, I was happy to accept her suggestion to 'meet up another time'.

With no more lectures that afternoon, I left campus after saying goodbye to Helen and went home, whilstling happily to myself when I strolled in. Tammy's car was in the driveway and she was standing at the kitchen sink washing dishes when I entered.

"Hi Tammy," I called as I wandered in.

"Oh, hi Paul," she replied.

"Did you get off work early today or something?"

"Yeah, things were quiet and I was feeling tired, so I pulled a sickie."

"You naughty girl," I sniggered.

Tammy was wearing her smart black trousers from work and a white blouse, the sleeves rolled up as she finished cleaning dishes. The soapy water gurgled as the sink's plug was pulled.

"You ought to give me a spanking," she quipped over her shoulder.

I approached her and clapped a hand to a lean, firm arse and stroked it, my prick stiffening.

"Or I may just fuck you hard!"

"That's not a punishment."

"Who cares?" I said into her ear, and kissed her neck lightly. I nibbled on her earlobes, sucking them, rubbing my bulging crotch against her arse.

Soon, I reached down and around Tammy, unbuckling her trousers and sliding them down, along with her white panties. She stepped out of them and bent over the kitchen counter whilst I unzipped my flies and pulled forth my erect cock. I edged up to Tammy and slid my cock up her cunt from behind, soon gripping her shoulders and fucking her. My sister's girlfriend breathed deeply and sighed in delight as I hit a good pace, fucking up into her tight slit whilst turning her on by informing her of my little tryst with Helen earlier.

It was nice to be fucking without a condom, Tammy's cunt affording a hot, moist grip on my rampant cock as I fucked her over the counter for a solid 15-minutes before climaxing. It timed perfectly with Tammy's orgasm, the two of us spluttering and gasping ecstatically as we came together, eventually slumping down to the floor, out of breath and satisfied.

A wet, Sunday afternoon in November. I was in bed with Tammy and Gemma, all of us nude and oblivious to the outside world, rain hammering on the window.

I was cunt-fucking Tammy doggie-style whilst my sister reached underneath Tammy and frigged her clit and pulled on her nipples

"Who fancies a change in position?" I asked when I withdrew from Tammy.

"How about we try something new?" Gemma asked as she got up. She hopped off the bed and me and Tammy watched as my sister fetched a strap-on dildo from a drawer by the bed. It was white, slender and about 7" long.

"That's not new," Tammy said, "We use that all the time."

"But not on my brother," Gemma grinned, "Do you fancy it Paul?" To illustrate her point, she fixed the strap-on to her waist.

"You wanna fuck me with that thing sis? In the arse?"

"Sure."

"Sounds like a good idea to me," Tammy added, "Come on Paul, it'll be fun. It is for me and your sister, so it will be for you too. Get into position. I'll grease you up."

Pretty much prepared to try anything out, I accepted this idea and got down onto my hands and knees whilst Tammy fetched some KY-Jelly and applied it to my arsehole. Gemma was now on the bed, the plastic-cock strapped to her crotch look rather menacing now as my sister slathered lubricant over it.

"Ready?" she asked.

I nodded over my shoulder. Gemma had a look of concentration on her pretty face as she looked down and prepared to sodomize her own brother.

Looking ahead, I felt my sister nudge the head of the dildo up to my anus. Tammy stroked my back and instructed me to relax, which I managed to do, closing my eyes as I felt the dildo begin to enter. My lubed arsehole opened up and the plastic prick slid into me. Gemma made sure I was okay and I confirmed that I was, the feeling of being buggered unusual but very arousing. Eventually, Gemma had fucked the strap-on up my arse to the hilt and held my waist as she fucked me.

"That good?" she asked.

"Very good," I told her, "Shit, yeah. It feels odd, but it's nice."

"It certainly looks as if it feels nice," Tammy commented from beside me, reaching underneath me and grabbing my cock, which had indeed got even stiffer and now jutted out like an iron-rod. It almost hurt it was so stiff, and I welcomed the sight of Tammy using the jelly to grease up her arsehole up. I knelt up, my sister remaining in my arse, whilst Tammy got on all fours in front of me and backed up so that I could ease my cock up into her rectum.

It felt fucking fantastic in this sandwich, the dildo my sister arse-fucked me with sending shivers of pleasure up my body, whilst Tammy's sphincter offered a hot, tight grip on the base of my cock. My orgasm was hard to fend off and soon I ejaculated in the depths of Tammy's bowels, almost doubling over as I came, my sister picking up the pace of her fucking behind me during my climax.

My dick only partially softened in Tammy's cum filled rectum before hardening again. The two women swapped places and we went at it for a second time, Tammy this time arse-fucking me with the strap-on whilst Gemma presented her arse for me to penetrate. I lasted twenty-minutes this time, my climax in my sister's bum as powerful my previous orgasm, and we agreed to try out this novel act in the future.

The following day, Tammy and Gemma had gone shopping for the afternoon, leaving me sitting on the sofa in my jeans and a black shirt, watching telivision.

I cracked open a can of beer and was about to take a sip when the phone rang. I picked it up.

"Hello?" "Hi Paul," came the voice of my sister. She was clearly on her mobile in a busy store.

"Oh hi Gemma." "Listen, can you do us a favour?"

"Sure. What is it?"

"Just a bit of entertaining. One of my friends, Natalie, is coming over to our house at two o'clock, about five minutes time. We're all going out afterwards. We completely forgot about it and we're half-way through plodding through the supermarket. We'll be another 45 minutes, or thereabouts, so could you do us a favour and just let her in and keep her company till we get back?"

"Sure sis," I said.

"Excellent!" Gemma responded, "Like I said, we utterly forgot she was coming round. You know Natalie don't you?"

"Yeah, I met her the last time she was round here for that party last week. She's the one with the shaved head yeah?"

"That's her."

"I got on fairly well with her when I spoke to her. We share a love of science-fiction books."

"Also, me and Tammy told Natalie about us. You know...us three, shagging."

"Oh right," I stammered. I'd assumed it'd be kept a secret.

"Don't worry Paul, she's fine with it. Natalie's totally liberal minded and wouldn't tell anyone else. Don't worry."

"Okay Gemma, whatever you say."

"Well, take care of her. Bye Paul."

"See ya sis."

I put the phone down and, just on time, the doorbell rang. I went to answer it.

"Oh, hi Paul," Natalie said from the doorstep.

"Hi Nat. Listen, my sister and Gemma are out at the moment, they're stuck at a supermarket and won't be back for a while. Do you want to come in?"

"Sure. You can keep me company."

I let her in and we went to sit on the sofa together.

Like a lot of my sister's friends, Natalie was a lesbian. She had very short hair that was dyed bright red and wore purple lipstick, torn jeans and a sleeveless white top that showed off the tattoos on her arms; a Ying Yang symbol on her right bicep, a CND symbol on her left. Each ear was pierced by at least six gold rings and studs, whilst she also had a small nose ring through her septum. Natalie was slim and 5'8", just a couple of inches shorter than me. At the age of 31 she was at the older end of the age range of my sister's social circle, though her hippy-student manner of dress and shaved head did make her look younger.

"Are you going out with the other Gemma and Tammy then?" I asked her as we both sat on the sofa.

"We're going shopping for clothes," Natalie repied, "then probably off clubbing in the evening."

We made small talk for a while, mostly about my course at college, Natalie having attended the same place years ago.

"Did you sister tell you that I know about you, her and Tammy?" Natalie asked shortly.

"She told me earlier," I admitted.

"Well, you don't have to worry, I'm not judgemental and I certainly wouldn't tell anyone. It must be great fun for you having two sexy women to fuck each night!"

"Damn right it is," I grinned.

"Gemma told me you take it up the arse too, with a dildo."

Such a brazen question coming from a woman I'd met only a couple of times did knock me off course, but I managed to nod calmly.

"I bet that's fun too," Natalie continued.

"It feels alright. If it's good enough for Gemma and Tammy, it's good enough for me!"

"I've got a favour to ask," Natalie began, edging up to me, "Could I, you know...fuck you? Up the arse with a dildo like your sister and Tammy do?"

"Er..." I stammered, "If you want."

"Great! I've always wanted to do it to a man, just to see what it's like. You can fuck me in return if you want, though for obvious reasons I don't have any contraceptives around so you'll have to take me up the arse."

"Has the definition of 'lesbian' changed recently or something?," I asked, amused, "You're the third I've met recently who wants to fuck me!"

"Your sister and Tammy are bisexual really, though more inclined towards women. On the other hand, I am a lesbian, but I'm not allergic to men, and I did fuck a few in my teens. A change every now and then is always nice. Shall we do it here now my dear?"

"Sure Nat. How about doing it here in the living room?"

"Can't think of any reason not too. Better shut the curtains."

I went to do just that whilst Natalie casually undressed. She was naked when I came back to her and I admired her body. It was curious how her features that appeared blatantly rebellious against traditional beauty - short, absurdly red hair, body piercings and tattoos - contrasted with the way her body was the archytypal feminine form; gracefully slim and sexy with pert tits and long, toned legs. She had a tattoo of an eagle across her lower back and a couple of Chinese symbols tattooed on her left arse-cheek, in addition to a silver clit-ring and a gold ring dangling from each nipple.

"Get naked then," Natalie smiled to me. I stripped whilst telling Natalie where to find a strap-on dildo - the white, slender one - and the KY-Jelly, which she eagerly retrieved.

I bent over the coffee table, gripping the edges and thrusting my arse out for Natalie's attention, the tall lesbian humming as she fitted the dildo to her waist. She slathered KY-Jelly over it then applied some to my anus before getting into position, the dildo head nudging between my bum-cheeks and against my greased arsehole. I relaxed as Natalie entered me, the plastic prick sliding up into me easily. We fucked silently, lost in pleasure, me bent over like a slut and Natalie humping my arse with great zest. Some little bit of homophobia in my mind nudged at me, suggesting that this was a rather freaky thing to be doing, getting arse-fucked, even if it was by a woman with a dildo. But I didn't care. I regularly fucked my sister, and her girlfriend, so why bother about any other taboos? Besides, it felt nice, my bum skillfully shafted and my prick fully erect and wobbling before me as I was buggered.

Natalie pulled out of me, panting for breath, after ten-minutes, removing the dildo and putting it aside whilst declaring how much fun it'd been.

"It was nice for me too," I told her as I turned round, my erection thrust out at her, "It felt good."

"Well I'm glad you enjoyed it," Natalie smiled, "I liked it too. Maybe it's a perverse enjoyment of role-reversal that excited the feminist in me, or just the novelty in it, but either way it was cool. Anyway," she continued, stepping up to the coffee table which she then bent over, palms splayed out on it's surface, her legs straight, back arched and her firm arse thrust out, "it's my turn to grit my teeth and take it up the bum!"

I used the lubricant to grease my dick up, then applied it to the rosy, hairless arsehole between Natalie's buttocks. The way having been prepared, I eased my cock up this horny dyke's arse, finding her shitter as nice and tight as either Tammy or my sister's.

Holding Natalie's waist, I buggered her whilst wondering what went through her mind. Was she imgaining me to be a woman, perhaps a specific one, using a dildo on her, or perhaps she was happy being fully aware that she was being anally serviced by someone of the 'wrong' gender to her? But then again, who cared? Whilst Natalie wasn't going wild with pleasure, she certainly seemed to be enjoying it, panting softly and joyfully, humping her arse backwards onto my dick to meet my thrusts.

My orgasm rose and exploded, my legs wobbly as I stammered and gasped whilst shooting my semen deep into Natalie's rectum. I kept thrusting throughout, my cock making sloshing noises as it was fucked in and out of a rectal passage quickly filling with sperm. When it was over I pulled out and Natalie told me I'd been a good fuck.

'For a man anyway', she'd added with a grin. We cleaned up, got dressed, and were sitting on the sofa drinking a can of beer by the time Tammy and Gemma arrived.

On a grim December day the weather was freezing cold, and I shivered as I hurried up the stairs of the accomodation block. It was mid-afternoon, a Monday, and having just finished classes for the day I had decided to visit Helen. She'd skipped the mornings class, as she occasionally did on Monday's if she fancied a lie in. I'd fucked her a few times since the other week and this set-up with the chubby little black 19-year-old proved to be a mutual satisfying relationship; she still had one night stands - or at least sought them out - whilst always knowing that I'd be more than willing to pop over for a fuck if she felt horny. Gemma and Tammy did provide more than enough opportunities for a shag, but I liked to fuck other girls as well. Helen and myself simply provided a convenient no-strings-attached sexual partner to each other during the week without having to regard ourselves as 'going out with each other'. It was perfect.

My arsehole ached a little from this morning as I walked. I'd joined my sister in the bathroom early that morning before she'd gone to work and I'd arse-fucked her on the floor, both of us dripping wet. I'd fired my load deep into her arse before Tammy entered the bathroom, naked, and dissapointed that I'd spent myself already. Knowing how to get me re-stiffened quick enough to have time for a fuck before work, Tammy had soaped up a dildo and buggered me on the floor. My cock had rapidly hardened as I was skillfully fucked anally. Mission accomplished, Tammy had withdrawn from me and got down on the floor so that I could fuck her up the arse. My sister meanwhile had put on the dildo and buggered me throughout this, stimulating me incredibly up to and throughout my climax. Despite two orgasms during these pre-breakfast activities, I was feeling horny again now, which was why I was visiting Helen.

I knocked on her door and she answered after some delay, her hair ruffled, wearing a tight red T-shirt under which her big tits bulged, and a pair of skimpy little knickers who's stark white cotton contrasted with her chocolate-brown skin.

"Hey Paul," she smiled, "How are you?"

"Fine, fine," I shrugged, "Just finished class."

"Yeah, I couldn't be bothered going. Did I miss much?"

"Not a lot."

"Well, c'mon in love. Come on."

She ushered me in, closing the door behind and instantly wrapped her arms round me and kissed me hard.

"You came just in time," she said.

"Why's that?" I asked with a grin, reaching behing her and sliding my hands down the hem of her panties and stroking her arse-cheeks.

"I'm fucking horny," came Helen's predictable reply.

"Me too!"

"Wanna fuck then?"

There was no need to bother answering such a question. I stepped back and quickly undressed, Helen doing likewise, both of us soon naked.

"You got any rubbers?" she asked, "I ran out."

"No," I told her.

"Oh well. Not to worry, wanna take me up the arse?"

I grinned. Whilst I didn't doubt this horny slut's willingness to try anything, she'd clearly enjoyed cunt fucking enough to not offer her arse to me, and I thought it impolite to ask on previous occasions we'd fucked.

Some face cream on the bedside cabinet hit my eye when I looked around for some lubricant. Helen was quickly on all fours on the bed, her big arse thrust out towards me, her lustful face glancing over her shoulder as I got in behind her, smearing the cream onto my cock, then her anus.

Helen's soft, plump brown body tensed and shuddered beneath me as I sank my dick into her arse before I commenced sodimizing her at a speedy pace that suited both of our pent up sexual desires. Helen got off on it greatly, grunting and moaning in pleasure, as did I as I gripped her waist and fucked my cock into the depths of her hot, clammy rectum.

I continued humping my pelvis throughout my orgasm, thick sperm flooding Helen's bowels whilst her sphincter twitched tightly round the shaft of my cock. After I'd withdrawn and we'd recovered from our exhertions, we were both horny again. Helen swung round on all fours and I slid my re-stiffened prick up her arsehole, and spent a further 30-minutes buggering her until my cream sprayed forth once more.

That evening I was stuck in the campus library, studying for an exam in a couple of days. My course was going well and my marks high so I wasn't too worried about it.

Fatigue and horniness tugged at me as I eventually went home, the winter night cold and dark by the time I entered the house. The living room main lights were off, just a lamp burning in the corner, and sounds from the bedroom made it clear where my sister and Tammy were.

I briefly entered my room to dump my college books on the bed and strip down to my boxer-shorts, before going back into the hallway where knocked softly on the door to the master bedroom.

"Come in Paul!" my sister called from within, and I entered.

Gemma was lying on her back naked on the bed whilst Tammy knelt between my her legs, also nude. She was fisting Gemma's cunt and continued to do so whilst turning and smiling "Good evening!" to me. I whipped away my shorts and hopped onto the bed, kissing both of my favourite tow ladies before offering my cock to my sister. She sucked greedily on it as it slowly pumped itself up to a full erection in her warm lips.

In the meantime, Tammy removed her fist from my sister's cunt and got Gemma to pull her legs up and apart a bit further so that her arsehole was presented to her. Dripping with cunt juice, Tammy's fingers were bunched up and pushed slowly into Gemma's arsehole, my sister taking my dick from her gob and crying out ecstatically as her anus slowly opened up. In less time than one might imagine, Tammy's whole hand was soon shoved up Gemma's shitter, the distended anus of my sister clutching and sucking at Tammy's wrist.

My cock nodding ahead of me, stiff and purple, I shuffled to the other end of the bed behind Tammy, who was bent over on her knees and one hand, presenting her arse whilst fisting Gemma's. I rubbed my cock-head against her moist lips before entering her, fucking her cunt doggie-style, able to look over her shoulder and watch her skillfully fist Gemma's arse, my sister wracked with ecstasy.

During this, I sucked on my thumbs and pushed them - one at a time then both at once - up Tammy's bum, loosening that puckered hole up. When I pulled my cock from her wet cunt, her arsehole was gaping slightly and ripe for fucking. With little ceremony, I pushed my dick up into Tammy's rectum, buggering her enthusiastically whilst she bucked her arse against my hips and egged me on. She eventually moved her head down and licked my sister's wet cunt and I later tugged my dick from her twitching arsehole and re-entered her cunt which I fucked whilst holding her waist tightly.

Soon, we broke the position apart, my sister now hungry for dick. Tammy strapped a dildo to her waist and lay down so that Gemma could mount her, sinking her wet cunt down onto the strap-on with her arse thrust out towards me, the stretched, yawning anus winking at me. In no time at all I got up behind her and fucked my throbbing cock up into her bum. My sister was driven wild with lust as she was cunt and assfucked by her lover and brother respectively, urging us on as she panted hard, hitting a climax after a short while.

"It's the Christmas holidays soon," Tammy said from below after Gemma had calmed down and we'd settled into a steady fucking pace.

"I've got one more week of class," I said, "Then I have a fortnight off."

"Cool. Are you going to mum and dad's house?" Gemma asked over her shoulder.

"I was going to," I shrugged, steadily arse fucking my sister as we talked, "I might stay here though for the holidays, if that's okay."

"Of course it's okay," Tammy insisted.

"Yeah Paul," Gemma added, "We love having you here. Stay for the holidays! Just tell mum and dad you're busy with college work or something. We'll all fuck through the cold nights of Christmas and New Year!"

"Okay," I smiled.

That sorted, we got back to fucking, Gemma expertly shafted up to a second climax as both her holes were serviced.

"Have you cum yet?" Gemma asked ten-minutes later.

"Not yet," I panted in her ear, "Why?"

"Shoot your load all over Tammy," she suggested, "Spurt it all over her face and tits so I can lap it up!"

"Sure thing sis. You up for that Tammy?"

"Definately!"

I eased out of Gemma's arsehole whilst she in turn dismounted Tammy who was quickly unbuckling the plastic-cock and tossing it aside. Tammy propped herself up on her elbows, and I knelt astride her. From the side, Gemma reached for my cock, gripping it in her fist before pumping it quickly and expertly. As she jacked me off, Tammy watched my swollen cock head, licking her lips as she anticipated the forthcoming fountain of spunk. The moment eventually came, Gemma jerking my cock throughout my orgasm as my sticky white jizz shot across Tammy's face. It streaked over her cheeks and slashed across her forehead and hair, big dollops landing on her extended tongue, enabling her to swallow down the salty fluid.

Finally finished, I moved back and let Gemma get down and lap up all the cum from her girlfriend's face. In the meantime, I busied myself greasing up my fist with KY-Jelly and pushing my hand up into my sister's rectal passage, my dick wilting, spent and satisfied, at least for the time being.

I was certainly looking forward to the holidays this year!
