In the dimly lit gym, a strapping lad hops onto the stationary bike, his eyes locked on the pounding rhythm of the virtual road. His breath quickens, not just from the exertion, but from the thrill of knowing he's being watched. His cock tents his shorts, and he gives in, stroking it to the beat of the pedals. His body tenses, and with a final, powerful thrust, he erupts, his hot seed painting the bike's frame.
