An Unexpected Orgy

(mF, mF, mf inc 1st, FFM~f)

It was a warm Spring afternoon and my sister and I were walking home from school together. At the time, we lived a in a fairly rural area and our 10 minute journey took us through a series of quiet country lanes. It was a journey we had done hundreds of times before, but this time it turned out to be far from routine.

We were about halfway home and passing one of the fancy farmhouse conversions that dotted our route. It was one of the biggest, grandest houses in the area and surrounded by a high red-brick wall that kept out prying eyes.

Our route took us around the back of the land, and past the rear gate. As we got close, we suddenly heard a loud, high-pitched giggle, followed by a whoop of laughter from what sounded like a man.

We both stopped in our tracks and looked at each other. "What the hell was that?" I asked.

Gina shrugged. "I dunno." She walked off the path and got closer to the house. A red wooden gate led into the garden and I watched as she paused next to it and listened intently.

We heard another squeal and then a flurry of giggles from a number of people. I could also hear the low beat of some dance music coming from inside the house.

"What's going on?" I asked.

"Ssshh," said Gina, putting her fingers to her lips.

I went over to where she was standing and we both put out ears to the door. It had gone silent, and there was no way to see into the garden.

Suddenly, I heard a voice from behind us. "Hey guys, what's up?" it enquired.

Gina and I jumped around, surprised that someone had been following us. The voice belonged to a man in his twenties -- tall and dark, wearing a white shirt and a pair of tan slacks. Beside him stood a pretty blonde girl, around the same age, wearing a short denim skirt and a blue crop top that hugged her medium sized boobs.

"You here for the party?" asked the man.

"Uh, sure," said Gina.

I shot her a look, but said nothing. Party? What party? She stared at me as if to say go with it, so I just stood there with a dumb look on my face.

"Great," said the man. "I'm Eddie, and this is Fiona."

"I'm Gina. This is my... uh, friend... Tom."

I mumbled a greeting to the two strangers and wondered why my sister had just introduced me as her friend. What the hell was she playing at?

Eddie opened the door and led us into the enormous garden. There was a barbecue already lit and a number of people were hanging out and chatting around the patio area.

We went through the patio doors and into the house, where it looked as if the party was well under way. People had gathered in the kitchen, dancing to the music, while small groups were scattered along the corridor and down towards the living room.

A man approached from the living area and greeted Eddie and Fiona with a warm hug. "I found these two outside," said Eddie.

The man took my hand and shook it vigorously. "Hey, come in, come in! Help yourself to food or drinks, have fun, the party hasn't really started yet, but it won't be long."

He hugged my sister. "Goodness, aren't you a sexy little thing!"

Gina blushed and laughed nervously, but my attention was grabbed by something I saw in the next room. In amongst the party guests, a women wearing nothing but a wrap-around towel danced between three men, kissing each of them on the mouth. Then she took one by the hand and led him off into the next room and out of sight.

"I'm Doug, the host. So do you guys know anyone here or did you see the ad on the internet?"

"Yeah we saw it on the web," said Gina casually.

"Cool. You both look a little younger than the people we normally have around. You sure you're both eighteen, right?"

"Yeah, we're both 18."

I was surprised -- and maybe even a little impressed -- by how easily Gina lied. As far as I knew, we had arrived here purely by accident and neither of us were 18. In fact, Gina was 17 and I had barely turned 15.

Although I was quite tall for my age, I was amazed that he had believed that I was 18.

"Great," he said. "I'll leave you to it. All the bedrooms are open and in bounds, there's a cloakroom where you can leave your clothes. Have fun."

He disappeared back in to the living room, and I took the opportunity to shepherd Gina back out in to the garden.

"What the fuck is going on?" I asked, making sure there was no-one within earshot.

"What do you mean?"

"Why are we here? Why didn't you say I'm your brother? And why do we have to pretend we're eighteen?"

"Sheesh, bro, relax. Look," she said, "I heard some rumours in school that this place throws some wicked parties, okay? They might kick us out if they know we just finished school for the day. So just chill out and have fun."

"So why was there a woman in a towel kissing random guys in the living room?"

"Ugh, jeez, Tom, you're so naive! Okay, okay, I think it's a swinger party. Satisfied? People come here to fuck each other."

I stood there, dumbstruck. How did she know about this place? "Are you serious? That's fucked up."

"I didn't know there was anything happening today, okay? I didn't plan anything. But when I heard the music from outside..."

"We should leave. This is too weird."

"Leave? Why?" she asked. "Aren't you a little curious?"

"Curious? Grossed out more like! You're my sister! Eww."

But in truth, I was curious. I was intrigued at how comfortable my sister seemed in the situation. I had expected her to be freaked out at finding herself in the midst of a swinger party -- but she wanted to hang around and do -- what, exactly?

"Look, we'll get in huge trouble if Mum or Dad find out we were here," I said.

"How are they going to find out? Stop being such a geek. Don't you wanna get laid? Now's your chance."

It shocked me to here Gina speak like that. She had always been more confident than me, sure. She'd had a number of boyfriends in the past, and I knew she'd gone further than just kissing, but this was crazy.

In truth, I was far less experienced. I had never had a proper girlfriend before, and the furthest I had ever gone was a kiss and a grope with one of the girls from my history class.

"Just stay for a while, okay?" she said. "You don't have to do anything, just have a drink and get some food from the barbeque. We'll meet back here in an hour."

"Why, what are you going to be doing?"

A devilish grin broke out across her face. "What do you think?"

I groaned inwardly. "Sis..."

She took my hand and led me into the house, past throngs of party-goers, all chatting and dancing amongst themselves. It got busier and busier as we went further into the house, and I figured there were at least a hundred people in attendance.

We stopped in the living room and I sat on the edge of the sofa. Gina paused and told me she was going upstairs.

"What for?" I asked, feeling foolish as soon as the words left my mouth.

"To have some fun. Stay here, don't move, I won't be long."

And with a wink, she disappeared, her hips swaying confidently as she headed for the stairs.

All of a sudden I felt nervous and self-conscious, sitting there alone with no-one to talk to.

The other people in the room were all at ease, laughing amongst themselves. Most were in their twenties -- attractive, confident -- and roughly split 50-50 between men and women.

I considered going into the kitchen to find something to drink, but as I was about to get up, someone sat next to me. It was Fiona, the girl we had met outside.

"Hey there," she said. "You look a little nervous. You okay?"

I nodded. As she sat on the sofa, her skirt had ridden up and exposed her tanned thighs. "I'm fine."

"Is it your first time?"

"Yes... I'm not really here for... I'm just with..." Suddenly I found that I lost the ability to form a coherent sentence!

Fiona laughed softly. She leaned towards me and put her hand on my shoulder. "You don't need to be nervous. We can go somewhere quiet if you like?"

I felt her thigh press against mine as she got close. I could smell her sweet perfume and feel the warmth of her body. Suddenly, she slid her hand up my leg and towards my crotch. My dick hardened inside my pants and I could feel a bead of perspiration form on my brow.

"Look, I don't know... it's just..."

She pressed her hand harder on my groin and moved her face close enough for me to feel her breath on my cheek. "You do want to, don't you Tom? Don't you want to fuck me? Isn't that why you're here?"

She stood up, took my hand, and led me through the hallway and into one of the small side-rooms on the ground floor. She closed the door behind us and beckoned for me to sit on the bed, which was situated at the back of the room.

I sat down and wondered what Gina would think if she found that I had left the living room. I also wondered what she was doing herself.

But my thoughts soon changed, as Fiona brought my attention to her boobs. She stood directly in front of me and guided both of my hands to her chest.

I stroked the outside of her top, feeling the hardness of her nipples through the thin cotton. My cock throbbed and bulged against the inside of my boxers. I could hardly believe what was happening.

Fiona knelt down between my legs and undid my fly, pulling my jeans off in one swift motion. My boxer shorts were next, and suddenly I was naked from the waist down.

My dick stood firmly upright and I saw a glint in Fiona's eye as she reached out to give it a squeeze.

"Wow," she said. "A big, juicy dick for me to get my lips around."

I groaned with anticipation and leaned backwards, pointing my dick in her direction. Then I felt a rush of pure adrenaline as she enveloped my penis with her mouth.

She licked hungrily at the bulbous head of my cock and I felt her tongue probe and push along the length of my shaft.

Unfortunately, my first ever blowjob didn't last too long, as she removed my dick from her mouth and climbed onto the bed alongside me.

We kissed passionately, our tongues clashing together, sucking, biting and licking. She unzipped her skirt and threw it to one side. My heart leapt as I saw she had been wearing no underwear. My first glimpse of real-life pussy.

I lowered my hand and placed in between her legs. I stroked the length of her slit, which to my amazement, was already moist and hot.

Her pussy was topped by a golden mound of soft, blonde hair, and I stroked it gently until I arrived at her clit. I fingered the small, round nubbin, making her groan and bite her bottom lip with joy.

We both took off our tops, making us completely naked. I squeezed her breasts, watching as my fingers left small marks on her supple flesh.

I kissed them, running my tongue over her nipples, taking them between my teeth and massaging them with my tongue.

I felt her hand grasp my cock, and it twitched violently in her hand as she caressed its thick shaft.

"Don't cum yet," she whispered. "There's plenty of fun still to be had."

I started fingering her, then kissed her cunt, burying my face in her golden bush before licking her slit. I held open her lips with two of my fingers and pushed my tongue in as far as it would go.

It was overwhelming -- the taste, the aroma, the texture of her cunt -- it was beautiful. I had experienced my first taste of pussy and found myself instantly addicted.

I lapped for minutes at her pink opening, exploring every inch of her vagina. I even forgot about my throbbing dick... almost.

Fiona was working herself up -- correction, I was working her up -- into an orgasmic lather. As my tongue did the business, she played her part by rhythmically fingering her clitoris. In time, her pussy got wetter and wetter. And as her pussy got wetter, I had more delicious juices to lick and savour.

I pushed my face even further into her cunt, until my nose and mouth were smeared with delicious girl-juices. Her slit was oozing a sticky, clear liquid, while her breathing began to get sharper and quicker.

Suddenly she gasped with delight, arching her back and squeezing my head tightly between her thighs. Her entire body tensed and she grabbed my hair, pulling my head more firmly into her pussy. She relaxed, before tensing again and letting out a loud moan of satisfaction.

A torrent of girl-cum flowed from her slit and I gratefully cleaned up every last drop. I suckled her swollen pussy lips, teasing them with my tongue until she finally relaxed into a state of contentment.

I lifted my head and gave my cock a squeeze. I had been so focused on eating her out, I had virtually forgotten about my throbbing erection.

"You eat fanny pretty well," she said, grinning from ear to ear.

I beamed, thinking that if I was that good on my first attempt, how good would I be with a bit of practise?

Fiona took one of the towels on the end of the bed and wiped between the sticky mess from between her legs. Then she gently took my penis and cleaned the pre-spunk from its tip. My balls ached, desperate for release, and I was looking forward to her taking me in her mouth and sucking me off.

Instead, she suggested we go back into the living room and find someone else to have fun with.

"Aren't we having fun here?" I asked, nervously.

"Sure, but the night is young," she said. "We don't want you peaking too early."

In truth, I was a little concerned about seeing Gina. What if she had returned from upstairs already and saw me leaving the room with Fiona?

I looked at my watch -- I had been twenty minutes with Fiona, but had agreed to meet Gina in an hour. That meant I had plenty of time to go out, find another girl, and get back here for some more action.

I made a grab for my jeans, which I had tossed onto the floor earlier.

"What are you doing?" asked Fiona.

"Getting dressed..."

"Wow, you really haven't been to anything like this before, have you?"

She grabbed the leg of my jeans and pulled them from me. Then she threw them over the other side of the bed and opened the door, beckoning me out.

"Naked?" I asked, hesitantly.

She laughed at my naivety. "Yes, naked, dumbass. You know this is an orgy, right?"

Suddenly I felt a surge of excitement at the thought of walking out there in the nude. My dick swelled with anticipation and I followed Fiona out into the passage way.

My erection bobbed up and down as I walked and I focused my attention on Fiona's arse and hips, which swayed back and forth in time with her stride.

In the time it took us to reach the living room, I thought about the turn of events that had landed me here. Half an hour ago I had been a 15 year old boy walking home with his sister. Now I was stark naked, walking into a room full of strangers, having just eaten the pussy of a girl I had only just met. Oh yeah, and I could bump into my sister at any moment... weird or what?

While I had been alone with Fiona, it looked as if the party had really sprung to life. The living room was awash with naked flesh. Everywhere I looked, I saw naked people.

I saw Eddie -- Fiona's partner -- on the couch having his dick sucked by a redhead with enormous tits, while Doug -- the host who had introduced himself to us earlier -- was busy screwing a sexy looking black woman with a hairy cunt.

I could hardly believe my eyes. There were girls kissing girls, guys getting blowjobs, women with dildos, all in the same room! It was like every wank fantasy I had ever had, rolled up and brought together in front of my very eyes.

Fiona gave my bum a squeeze and led me into the room. I sat on the edge of the couch, next to a pair of girls in their twenties.

One had small boobs with prominent, dark nipples, and she was reclined backwards with her arse propped up on a cushion. Her legs were spread wide, while the other girl -- a cute brunette with a red streak in her hair -- fucked her with a large dick-shaped vibrator.

Fiona sat on the couch next to me, virtually sitting on my lap. She began to masturbate me, slowly and gently, barely squeezing my shaft, which ensured I wouldn't shoot my load too soon.

"Touch her tits," she whispered.

The girl looked at me, although I could see in her eyes that she only had thoughts about the vibrator in her pussy.

I ran my finger over her nipples, and cupped one of her small breasts in my hand. She closed her eyes and sighed heavily, so I moved my hand over her belly and down towards her vagina.

I ran my fingers through her bushy mound of pubic hair, while Fiona began to kiss me on the neck.

Just as I felt myself beginning to come, she suddenly stopped stroking my dick. I groaned and instinctively dropped my hand towards my crotch, eager to finish the job.

She grabbed my hand. "Not yet. It'll be so much better later on if you let it built up." She shifted position and dropped her head, giving the bulbous head of my penis a brief kiss. "Trust me," she said.

My dick throbbed. It was glistening with clear, sticky pre-come, but I followed her lead and forced myself to leave it alone.

We left the two girls to play by themselves and I followed Fiona out through the other side of the living room and into a large glass-fronted conservatory.

It was quieter here and there were small groups of people seated and chatting between themselves. Most were naked, but a few still had their clothes on.

We approached one girl, who appeared to be on her own. She was a petite brunette with olive coloured skin and a delicate, pretty face. Her eyes were a beautiful deep brown and although she was wearing a sweater, I could instantly tell she had an amazing pair of tits.

"Hey Mel," said Fiona. "This is Tom. He's new here."

"Hey," she said. "I'm Melinda. Mel for short. A newbie, huh? You look as if you're enjoying yourself so far."

"I haven't let him blow his load yet," said Fiona, as they both stared at my erection. "I'm letting him build it up for later."

"Oh, Fi, you are mean!"

"I know, but that's the way they like it," she replied with a laugh. "Do you wanna join us? He eats pussy like a pro!"

"Oh yeah? He's a cutie, alright. And you know how I love having guys go down on me."

I stood there and listened, becoming increasingly self-conscious as the two girls loudly discussed my new-found skills as a pussy-eater. However, instead of being embarrassed, I felt a strange surge of pride as these two hotties talked about me in such glowing terms.

"Shall we go into one of the side rooms?" asked Melinda.

Fiona agreed, deciding that we should go back into one of the private bedrooms. She led us down a corridor and into a large room with a double bed.

Although I had felt a strange thrill being in amongst all that naked flesh, I was quite relieved to be back in private. Less chance of my sister seeing me in a compromising position!

Once the door was closed, I perched on the edge of the bed and watched as Melinda did a light-hearted striptease. I couldn't help but masturbate slowly as she shed various items of clothing -- first her heels, then her trousers, then her sweater.

By the time she was down to her bra and knickers, my tongue was virtually lolling from the side of my mouth.

I had been right about her boobs, too. They were spectacular. Larger than Fiona's, but still firm and bouncy, jiggling sexily as she danced in front of me.

She unhooked her bra and dropped it to one side, releasing her tits and revealing a beautiful pair of large, swollen nipples.

The pace of my stroking became faster and faster and another small bead of pre-cum formed on the tip of my aching penis. But before I could reach the point of no return, Fiona once again stepped in.

"Not yet," she said, forceably pushing me back until I was laying flat on the bed. She kissed me on the chest and on the neck, and my hand moved from my dick to the smooth skin of her bare arse.

Melinda climbed onto the bed next to us and I grabbed one of her juicy tits, squeezing it and running my finger in circles around her erect nipples.

I groaned as the two girls kissed, sloppily licking each other's lips and sucking their tongues. I pushed Melinda's knickers as far down as they would go, revealing a full bush of wiry, dark pubic hair.

The sight of her pubes turned me on more than ever. All of the cunts I had ever seen up until that day had been from porno movies. Nearly all of them were clean shaven, with perhaps a tiny strip of hair. Even Fiona was mostly trimmed with just a small bush.

But Melinda was completely unshaven. It came as a surprise initially, but it was definitely a pleasant one! Her cunt was stunning. I reached out and ran my fingers through her thick mass of hair until I arrived at her slit.

My index finger slipped in easily, and I pushed it in all the way to the knuckle.

I gave her a second finger, and then a third, and she shivered with delight as I moved them around, stroking the smooth inner walls of her vagina. "Do you wanna fuck me now?" she asked.

I thought about it for a moment. Sure, I wanted to fuck her. She was naked, gorgeous and horny. My dick had been erect for what seemed like forever. My balls were throbbing, and I wanted to dump my load of spunk into her warm, welcoming cunt. But first, there was something I wanted even more.

"Can I eat you out before we fuck?"

"Oh, god, let him!" said Fiona.

"How can I turn down an offer like that?"

We all shifted position. Melinda lay on her back in the middle of the bed, her head propped on two pillows. Fiona lay next to her and started stroking her nipples, while I knelt on edge of the bed and opened Melinda's legs.

I began by kissing the soft flesh of her inner thighs, slowly working downwards until I could feel the tickle of her pubic hair against my face. I inhaled deeply, savouring the musky aroma of her dark bush and buried my face in her cunt.

She let out a low groan of satisfaction. "Mmm, put your tongue in there, honey."

I did as she asked, opening her pussy lips with my fingers and thrusting my tongue into her pink slit. She was looser than Fiona, so I managed to stick a couple of fingers in there too.

"Oh, harder, harder. God, I love a guy who knows how to use his mouth!"

I moved on to her clit, which was shrouded by pubes, sucking it and licking vigorously until it was slick with my saliva.

Although my view was completely blocked by Melinda's pussy, I felt Fiona moving on the bed. "Where's Alan?" she whispered.

"Upstairs," said Melinda. Her voice was quiet. Huskier. "I think. He was with a girl."

"I'll go find him. I need a cock now."

Fiona left the room, closing the door behind her. I lifted my head and ran my hands down from Melinda's tits to her bellybutton and back again. "Who's Alan?"

"My boyfriend. Our boyfriend. We kinda share him."

"Cool," I said, diverting my attention back to her furry twat.

Minutes passed and Melinda got wetter and wetter as I continued to probe, lick and suck.

Again, I forgot about my own sexual needs and became entirely focused on bringing her to orgasm. She occasionally moaned -- whimpered slightly as my tongue hit a good spot. I found that she liked it best if I spend a while on her meaty outer lips, stroking them with my fingers and licking them slowly, before going deep, thrusting my tongue into her cunt opening and pushing it in as far as it would go.

That caused her to writhe on the bed, grasping the sheets and letting out a long, low groan of joy.

Within a few minutes of discovering this technique, I could tell that Melinda was almost ready to cum. Her slit become slick with a thin, transparent sheen of aromatic liquid, which I had no hesitation in lapping up with my tongue.

I began stroking her clit, gently pressing it with the tip of my index finger. Her breathing quickened and I felt her body tense.

But suddenly, before she reached that wonderful point of no return, I heard the bedroom door open.

My instinct was to look up and see who had entered, but Melinda prevented me from doing so by grabbing a clump of my hair and pushing my head back down towards her pussy. "Don't stop," she gasped.

I went back to work, thrusting my tongue in and out, over and over. It wasn't much longer before she reached the tipping point.

With one last tongue thrust, and a final stroke of the clit, I felt her entire body tremble, sending her into a series of ecstatic convulsions.

"Ah, fuck, fuck, god, oh, yes, yes!"

She relaxed momentarily, before tensing again as I pushed my face back into her warm, sticky mess of a cunt. Her pubic mound had become slick with a delicious mixture of sweat, saliva and girl-cum, and I kissed it again and again.

"Mmm," she said, squirming and writhing on the bed, "keep fucking me, don't stop. Don't ever stop."

But soon enough, she reached the end of her orgasmic throes and relaxed with a satisfied sigh. I gave her pussy lips one final lick, still lapping up her delicious juices, and lifted my head to see who had entered.

At first, I saw Fiona, still naked and gorgeous. Next to her was a tall, muscular man with a closely cropped brown hair. He was naked too, and stood there with his hand wrapped around his enormous penis. Must be Alan, I figured.

However, there was someone else in the room as well. Someone who gave me the shock of my life.

Standing slightly apart from the other two, nude apart from a towel wrapped around her torso, was Gina. My sister. I sat bolt upright and jumped to the other side of the bed, where I instantly covered my hard-on with a bed sheet.

I stared at Gina, hardly able to believe that she had been watching as I licked the twat of a complete stranger. She stared back, but neither of us said a thing. What was I supposed to say? "Oh hey, sis, having fun?"

To my amazement, a flicker of a smile flashed across her face. God, what was she playing at?

Fiona sat on the edge of the bed and grabbed a handful of Melinda's tit. "I told you he was good, didn't I?"

Melinda sighed heavily and let out a giggle. "He has a magic tongue."

Across the room, Gina looked at me and raised her eyebrows.

"So, who's next?" asked Fiona. "Gina?"

My heart skipped a beat at the suggestion. I knew that the situation was now in danger of spinning out of control -- I had to say something.

"Look, this has gone far enough. Gina and I, we're not boyfriend and girlfriend. We're..."

"...just friends," said Gina. "Old friends, since we were small. We've never been, y'know, together."

"What, never?" asked Fiona.

"No," said Gina. "I guess that's why Tom is a little embarrassed. It's a weird situation for us, isn't that right Tom?"

"Uh, yeah," I replied, still trying to figure out what she was up to.

"But, you want to, right?" asked Fiona. "I mean, you must have thought about it."

Fiona walked to where Gina was standing and tugged at the towel. Gina let it drop, and suddenly, my 17 year sister was completely naked, just a few yards away. "How could you not have thought about it? What a body!"

I knew I should have looked away -- made an excuse to get the hell out of there. But I was transfixed. I simply could not tear my eyes away from her beautiful body.

It was the first ever time I had seen her naked, and my cock bulged at the sight. She had small, pert boobs with light pink puffy nipples at the centre. She was slender, athletic even, with a flat tummy and narrow hips.

I let my gaze drop downwards towards her forbidden pussy. My cock throbbed even harder. Unlike Melinda, Gina was neatly trimmed, with just a small mound of hair above her clitoris. It was golden brown, just like the hair on her head, while the meaty lips of her labia were totally bare.

"How about it Tom?" asked Fiona.

I said nothing and watched as she began licking one of Gina's nipples. Gina pressed her back against the wall and closed her eyes, grabbing some of Fiona's hair and holding her head at her breasts.

Alan, who had been passive until now, also crossed the room and ran his index finger along Gina's pussy slit. His large penis bobbed as he knelt on one knee, squeezing her arse and massaging her cunt lips, slipping two fingers into her crack.

Melinda, seemingly recovered from her orgasmic exhaustion, sat up and shuffled over to where I sat. "Yeah Tom, how about it?"

She slid a hand under the bed sheet and easily found my erection. She wrapped a hand around it and began stroking it slowly. It was already covered in pre-cum, and her hand travelled easily up and down my sticky shaft.

She tugged the sheet and I let it fall away, exposing my cock to the full view of my sister. She opened her eyes and smiled at me. I smiled back.

"Tom?" she said. "It's OK. I want to."

I was stunned. Did my own sister just say that she wanted to have sex with me? Even more shocking, I found myself agreeing with her!

I had never, ever thought about her like that before. She was attractive, sure. That was obvious. Every boy in my school probably had wank fantasies about her. But me? Never. Not until that moment.

Now, though, I was naked, being stroked off by a gorgeous woman and watching her getting fingered by a bloke I had never seen before. It was a bizarre situation, but all I could think about was Gina. I couldn't drag my eyes from her tits. I longed to taste her pussy. I wanted her bad.

"Are you sure?" I asked, tentatively.

She nodded and climbed on to the bed next to me. Melinda shifted sideways and made room, allowing Gina to slip in between us.

Suddenly I became oblivious to the other three people in the room. I only saw Gina, my sexy sister. I reached out and gently placed touched her breast, running my hand under her tit and bringing it up to stroke her puffy nipple.

We both smiled, hardly able to believe what was happening. She touched my cheek and we brought our faces together, kissing each other softly on the lips.

"Our secret, okay?" she whispered in my ear.

I nodded and we kissed again, touching tongues. I felt her bite my lip, and suddenly her hand grasped my dick. It was the most sensational feeling I had ever experienced and I threw my head back in delight, letting out a low moan of satisfaction.

"Oh, god, Gina, that's amazing," I said.

I felt her fondle my balls, which were swollen and virtually ready to explode. I had never had so much prolonged stimulation without release before, and as Gina played with my nuts, I felt the need to cum more than ever.

In my peripheral vision I saw Fiona giving an enthusiastic blowjob to Alan, while Melinda was now amusing herself with a large blue dildo. But I ignored them all and focused my attention solely on Gina.

I pushed her down onto her back and positioned myself between her legs. I got a close-up view of her cunt for the first time and kissed it passionately. I didn't care any more -- all of my inhibitions had vanished. We had gone too far to stop. I thrust my tongue in between her swollen pussy lips and licked with all my might.

She squirmed and wriggled on the bed, arching her back and forcing her bum up into the air. She moaned and gasped, but I pushed two of my fingers into her cunt and frigged her.

My cock throbbed even harder and I reminded myself that I was fucking my sister. By now, that single thought was making me hornier than ever.

Now was the time to fuck. I pushed her legs further apart and guided my erection to her cunt. We were both hot and horny, and my dick slipped easily into her tight slit.

"Oh fuck, that's good," I said, feeling a tidal wave of lust wash over my body.

That's it, I thought, my virginity is gone. To my older sister -- and wow, it felt amazing.

I grabbed a handful of Gina's tits and looked deep into her eyes as I bashed away with my cock. What was there? Lust? Love? Sex? I couldn't tell, but I instinctively knew she wanted this as much as I did.

"Harder, Tom, fuck me as hard as you can. Rougher! Oh fuck, go for it! Bash my cunt!"

I pounded harder, shoving my dick as far as it could go. She took my whole length, thrust after thrust, until my balls slapped against the pale, white skin of her arse.

Before long, I felt myself approaching orgasm. With each pump of my dick I felt the sperm rise closer and closer to the surface until I dumped the whole lot into Gina's cunt.

I shuddered with ecstasy, shooting my spunk into Gina's hot minge. My balls screamed with joy and I grunted, falling forward until my mouth landed on one of her nipples. I sucked noisily, licking her tit as I felt her fingernails dig into my back and her legs wrap tighter around my waist.

I kept fucking, shooting another load of sperm, and then another. After such a long build-up -- so much anticipation! -- I never wanted it to end. It felt like no other orgasm I had ever experienced -- it was so much more fulfilling and intense than usual.

My heart pounded, and my whole body tingled, awash with an extraordinary feeling of contentment and satisfaction. With one last grunt, I emptied the last drop of my sperm into her vagina and withdrew my dick, collapsing in a heap at her side.

"That was... amazing," I said.

Suddenly, she grinned and opened her legs wide apart. She put her index finger in her mouth and sucked it sexily, before moving it down and sliding it into her cunt.

She wiggled it about, and then brought it back out, covered in a big dollop of my sperm. She sucked her finger, licking my spunk off until it was clean.

"Mmm, I love the taste of cum," she said. "Your cum, especially."

I watched with amazement as my sis repeated the process -- using her finger to scoop some of my spunk from her cunt, then suck it off. Who knew she was such a slut?

Melinda, who had been watching us intently while fucking herself with a dildo, came over and began to lick Gina's cum-soaked cunt.

Then Alan joined in, sticking his engorged dick in Gina's mouth. I watched as she licked and kissed his shaft before taking his whole length deep in her mouth.

Fiona then arrived, tenderly massaging my sister's body, running her hands softly from her cunt to her tits. I was in heaven and even though I had just cum, I felt my dick begin to get hard again.

Alan took his penis out of Gina's mouth and masturbated furiously, shooting a thick wad of spunk over her mouth and nose. Gina stuck her tongue out and licked the creamy liquid from her lips, before Fiona moved in and cleaned up the rest.

They kissed hard with open mouths and sucked each other's tongues. Suddenly, Gina's breathing changed, becoming harder and faster. As well as easting her out, Melinda was also using the dildo to fuck her.

Gina grabbed Fiona's hair and screamed with joy, arching her back and squeezing her thighs around Melinda's head.

Melinda stopped licking her and concentrated on her clit, rubbing it quickly and firmly with the tip of her finger. Gina screamed again, beating the bed with her fists and clenching the sheet. Fiona continued to kiss her breasts and nipples until she finally orgasmed in a rush of ecstasy.

Her whole body racked, squirming with joy and the electric satisfaction that only an orgasm brings. She moaned, half giggling, until she finally came to rest on her side, looking directly at me.

"Fuck, that was good," she said, breathlessly.

"It was good to watch," I said.

She turned to the others. "Guys, do you mind if Tom and I get a little privacy?"

"Sure," said Fiona. A few seconds later, Fiona led Alan and Melinda from the room, leaving me alone with my sister.

"What did we just do?" I asked. I could still see a shiny streak on her cheek where Alan's spunk was starting to dry.

"Well, we had sex with each other. You dumped your spunk in my pussy. Then you watched as I had some guy cum on my face and some girl fuck me with a dildo."

"I thought so. It's just that when I woke up this morning I didn't imagine this kinda thing would happen. Did you?"

"No."

"But you did know about the parties here, right?"

"I had heard stuff in school. Rumours about what goes on here. But I didn't know that there was anything happening here today. When we heard the music, I kinda figured out what was going on."

"But why did you come in with me? I'm your brother!"

She paused for a moment and I saw her gaze wander to my crotch, where my dick still stood erect and ready for action. "I dunno," she said. "I just kinda got carried away. I love having sex. I guess you didn't know, but I've had a lot of boyfriends already. And I sorta suspected you were still a virgin. I thought you may like get the chance to get laid."

"But then we ended up..."

"...fucking each other," she said, with a smile. "I never thought that would happen. But when I saw you..."

"Do you regret it?" I asked.

"God no! It was wonderful!"

Now it was my turn to smile. "It was pretty good, wasn't it?"

"The best. Do you wanna do it again? You didn't use your -- what did she call it? -- magic tongue on me!"

I laughed again. "Maybe not right now. I'm kinda exhausted. Tonight? At home?"

"Promise? I can't wait to feel what all the fuss was about."

"I promise."

We both got up and hugged. I felt the warmth of her body as we pressed against each other. Her boobs flattened against my chest and my penis brushed against the soft hair above her vagina.

We got dressed and left the party, walking the rest of the way home with our hands held together and a dumb grin on our faces. I couldn't wait until later that night.
