Later, the club started to fill up. The dance floor got more and more crowded. The three us had plenty to drink by this time and we were all feeling really good. When Sina and Felicia went to dance, they grabbed me and pulled me up onto the floor with them. The band was taking a break and the DJ was playing a long dance medley that just kept going and going with one song blending into the next. We were in the center of the dance floor with people crowded closely all around us.
A slower dance tune came on. Sina pressed her body close to mine and Felicia pressed her body close to Sina behind her. Sina put her leg between mine. She looked up at me and I started kissing her. The top of her thigh started sliding up and down against my balls. I felt myself swell to a full erection as I held her and kissed her. Both Felicia and I were holding tightly on to Sina's hips as our bodies ground against each other. Felicia was kissing Sina's neck and ears from behind as I kissed her mouth. Then Sina turned around to face Felicia. She was kissing Felicia passionately, full on the lips. I pressed my body against Sina from behind. I reached around her and started caressing her breasts. I gently pinched her braless nipples, which were so hard, through the soft cotton of her dress. I could feel Felicia's hard nipples rubbing against the back of my hands. The beat of the music got faster, but the three of us remained locked together. My mouth and tongue were running up and down the side of Sina's neck, which was still wet from Felicia's kisses. Felicia crouched down in front of Sina. She reached up under her dress, grabbed her panties, and slowly pulled them down and off. She stood up and handed them to me, knowing that I could put them in the pocket of my pants. I noticed that they were soaking wet. Then Felicia put her hand up inside Sina's dress. I couldn't see what Felicia was doing, but I felt Sina's breath become very heavy. The beat of the music was loud and unrelenting and there were bodies gyrating all around us. Were there people watching us as they danced? I'm pretty sure that they were. I pressed close to Sina, still caressing her breasts. I felt her whole body start to shudder and I knew that she was close to an orgasm. Then her hips started to rock back and forth so quickly as she went into an explosive orgasm.
We went back to our seats and started drinking again. I was trying to internalize what had just happened. A strange mix of jealousy and extreme lust was going through my head. I decided that if it made Sina feel good, then it was a good thing and I was okay with it. And Sina looked radiant! I could see the warm afterglow of her orgasm in her face.
When the club closed, we didn't feel like calling it a night. We sat on the beach and drank some more until it became very late. Sina and I had planned to sleep together, because my roommate Tom was spending the night at Sina's place with her roommate Teresa. Then Sina asked me if Felicia could stay with us too. I tried to act cool, but I was extremely excited. My heart felt like it was going to burst form my chest.
