A few months after our first mmf experience, me and Rachel experience our first foursome. We were at our friends house for his house party one summer night. And as the night when on only a few people remained. It was me, Rachel, the host, Jeff, Rachel's friend Crystal, and Chase. All of us were hanging out on the deck next to the hot tub. After a lot of drinks Rachel decides she wants to go into the hot tub. Chase immediately says he will get in if she goes in too. Then Crystal joins in and I do as well. After sitting in the hot tub and enjoying our beer the host and Jeff decide to go out for a beer and food run. Not long after they leave the girls decide to get out of the hot tub. Rachel runs in first and says she has dibs on the shower, and Crystal heads downstairs to change. While me and Chase sat in the hot tub he told me how he wanted to hook up with Crystal. So me and Chase got out of the hot tub and went down stairs to go talk to Crystal. We decided it was best if we went down in just towles and no underwear so we could surprise Crystal. After a few minutes of talking Chase's turns it into flirting and then he turns it into kissing her on her neck. Then before I know it Crystal had reached under both of our towels and pulled out both of our hard dicks. She played with both our cocks in her hand for a minute then pulled away because she felt bad she was grabbing my dick behind Rachel's back. I told her Rachel wouldn't have any problem with it, and that we should go join Rachel in the shower, and ask if herself if she is ok with it. So the three of us headed up there and got into the shower with Rachel. She was surprised at first but I told her the goal was to get Crystal and Chase to hook up. She doesn't hesitate and just begins making out with me and grabbing my cock. When I look up I see Chase and Crystal are doing the same. Then Rachel stops kissing me and leans over and grabs Crystal and starts making out with her. The water started getting too hot so I had to turn back to adjust it. Once u turned my head back around I saw Rachel was now making out with Chase and Crystal was just watching. After that I turned the water off and the four of us went into the bedroom. Me and Chase laid back on the bed and Rachel started sucking my dick and Crystal was sucking Chase's. Then Rachel comes up to kiss me and quietly asks if she can fuck Chase and if I can fuck Crystal. I of course agree to this and Crystal gets up on the table in the room and lays on her back. I get up and start fucking her. After a couple minutes she says she wants to take me to the living room to fuck me. As we walk out of the bedroom I noticed Rachel was still sucking Chase's sick and haven't even begun fucking. Chase said he was having trouble getting up as we walked out and that it may take him a while to get started. Once me and Crystal got to the couch she sat me down and mounted me. She started riding and moaning. I could tell she was getting close as her body tensed. It wasn't long after she let out a moan and I felt her pussy get soaking wet. I told her it was my turn and I wanted to bend her over. But then she started to freak out and begun to say she felt so awful for fucking her best friends boyfriend. At this point I think the alcohol was getting the best of her. Crystal decided it was best for her to leave so she went back to the bedroom. When Crystal barged into the room I saw Rachel was riding Chase's cock! Chase isn't quite as thick as me but he is just as long. Once Rachel saw how Crystal was upset she got up and helped Crystal gather her things and said she would take her home. Chase said it was ok and claimed he was still having problems getting up. So since Rachel wanted to take Crystal home we gathered our things and the three of us left. Chase seemed too drunk to care and stayed.
When me and Rachel got home she was very worked up. I kept prying her and asking how Chase's dick felt, but she claimed she didn't get the chance to feel it since he couldn't get up. I knew she was lying, and said from the looks of it you were riding his dick real good. She continued to claim she did not and I went along with it and ended up fucking her until we both came and went to sleep.
