One was bent over with his pants down and the other was shoving his cock into the other guy. Cheryl stopped me, placing her hand over my mouth. She th...n directed my vision toward the two men and began rubbing her hand through my back pocket until she had found her way to my hole. Then she inserted her finger, then moved her other hand and began playing with my now hardening cock. Her breathing was hard as she whispered in my ear how hot that made her as she watched the man slamming his hard. On weekends we use to meet up as much as posible at the malls, having lunches, watching movies and enjoying each others company. After a couple of months of dating it was a friday night, and I had organised with my parents to drop me off at the mall to watch movies with my friends, although actually it was to be with my bf. We had done this numerous of times over the last few weeks but on this occasion after greeting him with a kiss, he said let's rather skip the movie, get a milkshake and walk. Tyler and I quietly talked and came up with an idea. As this camping trip was all related to an ecology course that Tyler taught, we decided to have a quiz game. Since there were 7 guys and 5 girls, one of the guys had to join the girls. They wanted to know what they were playing for and Tyler just said that it was a great reward for the winning team, but they had to wait until the game was over to find out. They all agreed and Tyler wrote the rewards down, one for the guys and one for the. Sitting next to Jim was Brad, the short and kinda stocky white guy. Brad also had his pants down, and Debby was stroking his cock with her left hand as she sucked on Jim's.None of them had noticed her yet."Mmmmm that's it baby," Jim was moaning. "Suck it good."Then I closed the door behind me, and they all looked up, startled. Donna popped Jim's dick out of her mouth in surprise.For a second no one said anything. Then Jim and Brad started laughing."Well I guess she's learned that Debby really.
