Swingers Night

My ex and I had always toyed with the idea of having a threesome with another guy but it was usually when we were really drunk and really horny, usually the morning after I brought it up my ex would say something like don't be silly we don't need to. I used to dream of watching her being with another guy because she was amazing in bed and all I really wanted was to watch her blow someone elses mind. This went on for months and I had all but given up hope. It was new year's a few years ago and we decided to head into the city with a couple of really good friends of ours, they had been together for about the same time we had and as usual after a few drinks the conversation would turn to sex. I jokingly said that (ill call my ex Jane in this story) wanted to have a threesome with a guy but we couldn't find anyone. Jane slapped me across the head and said don't be an idiot, Paul and Sarah (our friends) just laughed along but all of a sudden were very interested. Seems that they were looking for the same thing (amazing what alcohol brings out in people). Sarah was a stunning girl and I had masturbated over her many a time and I know my mate fancied my ex, who wouldn't she was a gorgeous girl. The more we drank the more detailed the conversation got, at this stage all four of us knew where this was leading but noone was game enough to suggest it. After catching glimpses of Sarah's pink g-string under her dress 3 or 4 times combined with the alcohol and the sex talk I was getting ready to blow. Midnight hit and Jane kissed me hard and I was getting a massive hard on, as I turned around to hug Sarah she pulled me in close and grabbed my cock through my pants and was basically wanking me through them, Jane must have caught a glimpse of what was going on as I turned around to find them two making out, here is one of my best mates making out with my girlfriend in front of me and it was so hot. With that we all made our way towards the exit, I was holding Sarah's hand and my mate was holding Jane's as we stumbled back to our apartment. We got back and Sarah and I headed to the basement to get some alcohol from my car while the other two went upstairs, as soon as we were out of their site Sarah jumped up and wrapped her legs around me and started kissing me hard, the top of my cock was poking up out of my jeans and placed perfectly to rub her pussy through her g-string. I carried her to the car and sat her down on the bonnet, she instantly slid down and unbuttoned my jeans to start sucking me, at this point my cock was bigger then I had ever seen him as she started on him. I could see her fingers glistening with moisture as she rubbed her pussy and I thought I need to be in there ASAP, I pulled her up and layed her on the bonnet, i moved her g-string to the side and my cock slid in with ease even though she was so tight, she whispered in my ear "you are bigger then Paul, go slow" that made me feel good inside but then I remembered that Jane and Paul were upstairs, in my drunken state I had forgotten about them and that more then likely they are upstairs doing the same thing, this turned me on like nothing else as I started thrusting hard into Sarah, she was playing with her clit at the same time and we started coming at the same time, just as I felt myself about to explode Sarah grabbed my hips and pulled me in deeper as I blew deep inside her. I pulled out slowly as my come started to dribble out of her pussy. She sat up and kissed me hard again and said let's go upstairs and live out some fantasies. I didn't know what to expect as we walked up the stairs and I was hoping they were doing the same thing otherwise we just made a huge mistake, as soon as we opened the door both our prayers were answered as they were on the floor in the 69er position, my ex had slipped into some stockings and a little babydoll nighty and my cock instantly grew again. Jane sat up and called me over as Paul worked on her pussy, she said that she didn't want to lie and before she got changed they had fucked on the couch, she said that she hoped we wouldn't be angry. Sarah grinned and walked over to Jane, grabbed her fingers and pushed them to her pussy, as soon as Jane realised that was come inside her pussy she started grinding hard on Paul's tongue and kept fingering Sarah's pussy. Paul grabbed Jane's hips and pushed her down to his cock as she sat on him slowly, that moment was the hottest of the night for me, watching my girlfriend slide onto another guys cock in hot lingerie while fingering a girls pussy. I started wanking next to Jane's face as she grabbed my cock and started sucking me, she finally got to live out her fantasy of being with two guys. Jane had never hinted at wanting to be with a girl so when she pulled Sarah's pussy to her tongue I was in absolute heaven as was Sarah. None of us 4 had ever had a threesome so it was all new to us. I sat back on the couch and grabbed Sarah's hips and pulled her back onto my cock, she was riding me reverse cow girl style, this girl knew how to fuck as my cock kept growing inside her. Jane surprised me again as she got on all fours infront of Sarah and started licking her pussy, Paul moved in behind her and started fucking her hard, what a sight that would have been for an onlooker. For the next 20 minutes we all swapped positions as I moved behind Jane while Sarah rode Paul and then Sarah on all fours licking Jane while riding Paul. Sarah whispered something into Paul's ear and he smiled and nodded, he pulled his cock out and slid it into her ass slowly, she called me over and said you know what to do. I didnt need a second invitation as I slid into her pussy, Sarah was screaming as we filled her up, Jane just sat next to us playing with her pussy and then said my turn! Again I was surprised as we did anal once every blue moon, as Paul was smaller he slipped into her ass while I fucked her pussy, Jane screamed even louder. Suddenly I heard Paul let out a moan as he shot load after load into Jane's ass, this set me off as well as I pulled out and both the girl jumped infront of me, I covered both of them in come and what a sight as they kissed it off each other. All four of us were spent and still so turned on. We all jumped in the shower and it wasn't long before hands started wandering again. We didn't get a minute of sleep that night, after that night they were upgraded to our best friends and we used to play weekly together but I will never forget the first time.
