So we went to school that day and I was wearing her white silk bra and nickers which turned me on so much and she was wearing my black boxer shorts. I... was a job to try and hide the underwear under my shirt but I had manadged it until it came to PE time and I was in the changingand everyone had left or so I thought and I started to get undressed when my teacher came walking in and just stood there staring at me in my girlfriends underwear. He did not say anything at first but then he came. “Fuck me hard!” was all Kelly said.Mike plowed in and went as hard and as fast as he could move that appendage. It seemed like Kelly was coming on every third or fourth stroke.Alex’s big cock shot off a load into Lisa. Lisa rolled onto her back right next to Kelly and said, “You have to share him. I insist!”Mike slowed down. Kelly nodded yes. Mike moved to Lisa and her wet open hole, courtesy of Alex who also left a nice load of cum lube. Mike went slowly at first.Lisa barked, “Fuck me. I was always fantasizing of my teacher fucking me. Also, I think she was into girls too. Except, she'd just compliment them and sometimes I saw her buying them things. Maybe to keep the attention off herself with all the teasing she was doing to the guys in the class. She’d also take some of the girls out to dinner off-site. I’m not sure if she actually was putting the moves on the girls, but she was definitely paying them off so they were not interested in what she was doing with the guys. . That day went like that, and after a week or so one of my friends introduced him to me in the college library. Both of us acted as if we have never seen each other before, and greeted each other. He had a naughty grin in his face. Few more days passed and we used to greet each other whenever we met. One fine day, all of my friends went for a movie bunking the class. I wasn’t interested in that movie so I didn’t go. That was the turning-point day. I was in the cafeteria having lunch all alone.
