In and out of my red singlet at the gym

There was a guy watching me pushing weights with my legs in my red Bumchums singlet. He had positioned himself for the best view. I know when I do leg stretches he pulls the material so much you can see my hole through my singlet. Maybe that's what he was enjoying. If only he'd come upstairs shortly afterwards to watch me slip out of it in one of the quieter rooms and try to manage a raging hardon.
