Marty plays Voleyball

We got divided into the teams and made to play volleyball. I didn't notice in the changing room because of how things went, but my PE t-shirt was one size smaller then my regular one and clung to my body even more then that one. It was also thinner, so now the curves of my breasts were even more visible, along with rock-hard nipples almost poking holes through it.

Inside my shorts ... well inside my shorts my dick was hard. As hard as it gets these days, it was mostly just my glans sticking out. My glans that was now rubbing against the inner-netting of sports shorts with every move.

I tried my best, but with every move my dick would get teased by the net, and my nipples would get rubbed by the shirt. With every jump, with every run, I was getting hotter and hotter. When it was my time to serve I barely managed to hit the ball, and it flew so badly that it didn't even hit the net on our side. Out of pity enemy team allowed me another try, this time it at least did hit the net, but obviously didn't' go through and we lost a point.

I was breathing heavy, my pulse was racing. I finally recognized the sensation I have not feel in weeks - I was close to an orgasm! I have to leave. I have to leave before I cum here on the play-field in front of 11 of my male colleagues and a trainer!
