I got out, confused. --- Later that evening after another camp-side dinner, the girls declared that they wanted to go to the dance floor. The site had...a DJ every Saturday evening. I certainly wasn’t interested in dancing, so I left them to go off on their own. “At least Katie is wearing something decent.” I thought to myself. She had put on a sweater and jeans for the evening. I sat in my tent reading, fell asleep for a while and then woke up when I heard them coming back at about midnight. “It. We’d had so much fun with Colleen, we wanted to keep it going. Finally an opportunity presented itself as Katie and I sat together in the break room working over a late lunch. Colleen walked in grab bottled water and a snack.

I moved in front of her and she quickly opened her mouth. Robbie looked up to see my balls above his head, but said nothing as I fed my cock into Lisa’s mouth. Lisa’s moaning felt great around my cock and she rocked back and forth between us when I got an idea.“Hey man, stick your finger up her ass. See what she does.” I suggested. I could see Robbie reach his hand around Lisa’s perky butt. The brunette let out a gasp and tried to lift.
