Gympregnation

... for a bit of relief. It was getting harder to think clearly. I knew that by this point I was grinning like a silly girl with a crush as his eyes roamed over my body more and more shamelessly, but I couldn't seem to stop myself.

YOU'VE GOT TO RUN AWAY BEFORE IT'S TOO LATE!

At that moment, however, he lifted his leg onto the machine beside me, and I was suddenly face to face with his growing cock, every vein clearly visible through his skin-tight compression shorts as it inched longer and longer.
