This all happened at a ski resort in the Poconos.
I live in north NJ and my middle school had a ski club. We would go to a resort in PA and ski (duh). But my most memorable experiences in the club were not on the slope but in the lodge.
Me and some of my friends camped out in the corner of the lodge where very few others were. We sat down to eat dinner and the discussion moved to sex. We were all horny kids and were all perfectly comfortable talking about it. After a couple of minutes I felt myself getting hard and I looked at my friend's lap to see that he was too. After another minute he started trying to rearrange his boner when a girl at the table named Melissa saw what he was doing.
She proceeded to grab his dick through his pants and rub it a little. We all stopped and stared. The girl next to me decided to follow Melissa's example and do the same to me. I had received handjobs before, but the public setting had me really turned on. I let her rub my dick through my pants for a minute, but I was starting to get bored so I made a daring move: I lifted my butt up and yanked down my pants, leaving my boxers on. I then reached into my boxers and pulled out my dick which impressed the ladies. My girl started really jacking me off and Melissa soon had my friend's pants down just like mine. After another minute, I shot my load onto the table in front of me and then my friend shot his load onto Melissa.
We got ourselves dressed and cleaned up but left my cum on the table for the next lucky customer.
