Party gets real fun SeXStoRY

In my third year of college I was invited by a friend to a "Wear what you wear to bed party". Ok, I thought, could be interesting. It was held in a really nice, big house. When I arrived there were about 100 people there or more. Most of the people were in the basement hanging out in the huge f****y room, or the game room. The dress was interesting too. Normally I sl**p naked, but I couldn't wear that to the party, so I wore a t-shirt and sweat pants. Lots of the girls were dressed the same, although there were more than a few wear satin or silk two piece sl**p sets. Nipples were every where and it could be quite distracting. As the night wore on and the crowd thinned it became evident that a bunch of the silk/satin wearers, were actually staying overnight. As such they were getting pretty hammered and uninhibited. There was one girl, Jenn who I had been talking to and flirting with all night. We were sitting on the couch making out. At one point she stopped me from kissing her and took off her top. She claimed she was hot. There were probably about 20 people in the room. I looked around and saw various couples in different states of undress. There was one couple on a chair near by that were fucking vigorously with her on top. With a quick count I saw that the girls outnumbered the guys by quite a margin. I got back to Jenn and I was sucking and playing with her nipples and she reached into my sweatpants. My cock was very hard and she wrapped her hand around it and stroked it gently. I put my fingers inside the leg hole of her shorts and found her dripping shaved pussy. We played with each other for a bit, while we watched the goings on around us. Right on the other side of the long couch where we were there was a guy who had two girls on their knees sucking his cock. The couple across the way had stopped fucking but his cock was still inside her. She was in reverse cowgirl and he was stroking her clit and nipples as she watched and moaned. On the floor there was a tangle of bodies that seemed to be about 3 guys and 7 or 8 girls. Everybody there was licking or sucking someone else. The noise and smell of sex was incredible. Every once in a while someone would cum loudly and others would clap and cheer. It really was kind of nuts. My cock was ready to burst soon and so I took off Jenn's shorts and slide my sweats down my legs. She mounted me reverse cowgirl and started riding slowly. One of her friends came over and they started kissing. Soon the friend worked her way down Jenn's body until she was kneeling in front of us. She was licking Jenn's clit and my cock as it became visible. Every once and a while Jenn would lift up and the friend would take my cock into her mouth and then Jenn would get back on. Soon the friend got caught up with the group on the floor and she was not with us anymore. One of my buddies came over and Jenn sucked his cock while she fucked me. He moved off because he did not want to cum yet. One girl sat down across from us and she was still dressed. She had her hand inside her shorts and was obviously masturbating. The exhibitionism got us both pretty excited and we really wanted to put on a good show. I soon found out that Jenn was the s****r of my buddy who had invited me. She led me and our watching friend up to her bedroom. She had a big room and a king sized bed, which blew me away. Once on the bed I had her legs on my shoulders and I was going at her hard. Our watcher got naked and sat nearby masturbating. Her moaning was really exciting. I held off cumming by changing positions often but soon I had to blow. I put my cock between Jenn's ample tits and titty fucked her. Every time the head of my cock would poke out from between her breasts she would lick or suck on the head and this set me off. I came all over her chest and face. Our watcher was rubbing herself furiously and came at about the same time. Jenn got up and cleaned up and I introduced myself to Suzy, the watcher. She was shy and embarrassed at this point, but warmed up quickly. When Jenn got back they chatted and I found out that Jenn knew her casually. The three of us were still naked and soon we engaged in some serious play. I got to fuck Suzy in the doggy position while Jenn and her 69ed. I came inside of Suzy and we all crashed. The next morning I helped clean up after the party. We needed to do some serious work and rent a steam cleaner to get the cum stains off of the carpeting and on one of the chairs in the game room. It was a great night and well worth the work the next day.
