The work conference had gone well, and I went to the post-conference after-party. Management had put money behind the bar for free drinks, and I guess I had overindulged. I felt quite tipsy as I walked out into the cool evening air towards the accommodation rooms.

I stumbled a little and then felt a hand around my waist, steadying me. "Go carefully," he said, "we don't want you falling, do we? I'll help you to your room, or why not come to our after-party in the lounge?"

I didn't normally go to these, as I had heard rumours that they could get really naughty. People were being stripped naked and fingered until they reached orgasm. Someone even got rough-fucked, but tonight the drink spoke for me. "Why not?" I said. I feel randy and want to get fucked tonight."

We stopped in a quiet, dark corner. Dave pulled me close and kissed me. I returned his kiss and felt his hands slip under my top and squeeze my breasts. "Mm, that's nice," I whispered. I guess I had permitted him. It felt so good. My nipples started to harden due to both the cold air and Dave rolling them between his fingers.

I kissed him again, this time more passionately, and our tongues intertwined. It must have been five minutes before we broke off the kiss, during which time his hands had moved from my tits, down to my naked pussy, and were finger-fucking me like mad. "I could let you do this all night," I said, my breathing getting heavier and heavier.

"We had better get moving," he said quietly, "or we will miss all the fun. There will be time for some more of this and a lot more later at the party."

"More! Then I will look forward to that a lot," I said, without thinking. Had I just given Dave permission to play with my tits, finger-fuck my pussy, and perhaps even fuck me, later at the party?

Roy's words, as he had kissed me goodbye earlier in the day, resounded in my head: 'You're a free agent tonight; enjoy yourself, don't hold back, let yourself go, get kissed and kiss back, let them touch you up, lose your clothes, get fingered, and get fucked whilst you're naked if you get the chance.' Then come back and tell me about it as I fuck your brains out. I felt my pussy getting really moist at the thought of what I was going to let happen to me.

We reached the lounge, and things were already in full swing. Someone pulled me away from Dave and started to kiss me.

I felt two hands slip under my top from behind and start to squeeze my nipples, which by now were fully erect. "They feel so good," he whispered in my ear as he nuzzled my neck and kissed me. I felt so aroused and excited. Fingers found my pussy; it was so wet, they had no problem penetrating me, teasing my clit, and finger-fucking me.

"Keep it up and enjoy my body," I told him enthusiastically. "I feel so randy, I want a bit of everything tonight, I've got no limits".

Then Dawn called out. "Let's play Spin the Bottle. The first girl, fully naked, gets to be our victim for the night.

Dawn went on to explain, "The rules are: when the bottle stops on you, you must let the person on your right take off one item of your clothing. It's their choice, and if they leave any part of your body exposed, then you must let the person on your left play with that exposed body part. They can use their fingers, mouth, or tongue on you, but no fucking. You must not resist in any way."

I gulped, remembering that I was only wearing a short skirt and top with no bra or panties. I had left my shoes by the door. That meant that the bottle only had to stop on me twice for me to be fully naked and their victim, whatever that meant. The thrill of being naked at the mercy of this group made my pussy even wetter.

"Spin, spin, spin." I joined the call, and the bottle slowed as it reached me, but did not stop. It went two past me, stopping on Sam, who stood up expectantly. She held her arms in the air as Steve slid her jumper slowly over her head to gradually expose her ample breasts; she wore no top or bra underneath.

Her tits slowly appeared, her nipples first coming into view, brushed by Steve's fingers; they looked magnificent with their dark pink, engorged nipples and large pink crinkled areolas surrounding them. Alan sprang to his feet; Sam held her arms behind her back, pushing her tits out towards him. "Suck on these beauties," she called out.

"Suck, suck, suck," everyone called enthusiastically. Without hesitation, Alan opened his mouth, and Sam's right nipple disappeared from view as he sucked it in. His left hand found her other tit, and he rolled her nipple hard between his fingers. Sam threw her head back and squirmed, obviously enjoying the action.

"Make her cum, make her cum" we all called out.

Everyone started counting. When they reached one hundred, they called "spin, spin, spin" loudly again.

I watched the bottle turning, and again it slowed as it approached me, but this time it stopped. I stood, now knowing what was expected, and waited excitedly. I felt my pussy drooling as I stood with my arms behind my back.

Alan slowly undid the buttons on my top and brought my tits into view. Nipples first and then my full breasts; he took the opportunity to fondle them as he pulled my top open.

"Off, off, off," they all chanted eagerly, and Alan slid my top over my shoulders and let it drop to the floor. I felt no embarrassment, just pleasure as I felt Dave's mouth sucking on my hard nipple, but then, to my surprise, Alan took my other nipple in his mouth.

"Make her cum, make her cum," was called by everyone in the room, and again, everyone was counting to one hundred. It was all I could do to stop myself from cumming immediately, as they both sucked me really hard. I have never had two men suck on both nipples at once. I was in ecstasy. All too soon, the count got to one hundred, and my turn was over. I had made the count without cumming on this occasion.

My heart was racing, and my pussy was pounding as the bottle stopped near me a couple of times. Once on Sandra, who also now had her tits exposed, and once on Brenda, whose enormous tits were held in check by a very large bra. Then it finally stopped on me again.

'Well, here goes,' I thought, and stood in readiness. Alan placed his fingers at the front and rear of my skirt and slowly slid it down. He made sure his fingers had enough time to feel up my clit and penetrate my now-dripping pussy. I felt his other hand probing my arse slit and slipping into my anus.

I stepped out of my skirt, leaving him still double-fingering me as everyone watched. It was so erotic, standing naked in front of everyone as they watched Alan fingering two of the most sensitive parts of my body.

I held my hands on my head eagerly as they watched in silence for a good five minutes as he manipulated me. There was no counting; they just let him take as long as he wanted.

Then the call came, "Victim, victim, turn for us." He withdrew his fingers, and I slowly rotated in the centre of the circle, knowing that everything had been thoroughly stimulated and was now fully exposed to everyone.

Someone produced a blindfold and a nipple chain from somewhere, and the world went black. I felt my hands being tied behind my back, my nipples being clamped, and heard "grope time" called.

A draft of cool air blew over me for a moment as if a door had been opened. I thought nothing of it, but Roy had slipped quietly into the room and sat on a chair in the corner. His arms and legs were bound to the chair, and without my knowing, he was watching everything intently.

Someone's lips started to kiss mine, and I felt hands, everyone's hands, feeling up every part of me. Fingers were rolling my nipples and pulling on the chain as others squeezed and slapped my breasts. Hands squeezed and spanked my arse; some stroked my pubes, whilst some fingers found their way into my moist pussy and rubbed and pinched my clit. There were women's hands and men's hands, and I did not know who was touching what. The women, however, seemed rougher on my sex.

It was all I could do to hold myself back, but then I felt my back arching, and I came with the most intense orgasm ever. "She's really enjoying this," Sam called as I came for them.

Alan said, "Let's keep it up then, and make her cum again." I was cumming for nearly a minute as they fingered me, but they did not let up.

Sam called "all change," and I felt the hands moving to different parts of my body, all getting a chance to feel up every sensitive part. As the fingering continued relentlessly, I felt another orgasm building.

"She is nearly there again," Sam called. "Turn it up, everyone; let's give her an orgasm she will remember all of her life." The fingers seemed to get even more intense and rough as my back arched again, and the orgasm wave flowed over me. I had never felt pleasure like this before; every part of me shook as I came for them. As my orgasm subsided, I felt the fingers and mouths move away, leaving me a quivering wreck in the middle.

'Spin the bottle to see who gets to fuck her,' they said. Still being bound and blindfolded, I could not resist or see who was chosen. I was pulled down. My arms and legs were held, someone pulled on my nipple chain and I felt a large dick penetrating my pussy. It was much bigger than Roy's and really stretched me, pushing in deep until it found my cervix. Then it started to pound me, back and forth, in and out. It was painful but pleasurable at the same time.

Amazingly, I felt another orgasm building, my back arched again, and I shook whilst impaled on this huge cock, which itself exploded inside of me, filling me to overflowing with his spunk. He slipped out as it shrank back, and I felt his cum oozing from me.

Without a sound, Roy was released and slipped quietly out of the door through which he had entered. He winked at Alan as he left.

Someone wiped up the mess. My hands and legs were released, the nipple clamps were pulled off and the blindfold was removed. I looked around, blinking. I saw cameras and phones. There would be photos of me everywhere. I knew everyone had explored my body, but I did not know who fucked me that day.

When I arrived home the next day, I found Roy looking at photos on his computer.

"Look what Karl has sent me," he said. He turned the screen, and there I was, fully naked, my hands bound, nipple clamps and chain on my breasts with hands exploring me and fingers fucking me. A big smile was on my face.

I was shocked, then Roy spoke, "I don't have to ask if you enjoyed the after-party, do I?" I just didn't know what to say, but after a very pregnant pause, Roy said, "Let's fuck, and let's do it on the back lawn where anyone can see."
