Professor Dotadu, the hot, muscular gym instructor, sneaks into the empty toilet for a private moment. He locks the door, turns on the faucet to mask any noise, and pulls out his thick, uncut cock. He strokes it slowly, feeling the veins pulse with desire. He lets out a quiet moan, his body tensing as he imagines the tight, wet holes he'd love to fill. His strokes become faster, more urgent, until he can't hold back any longer. With a final groan, he releases, his hot cum splashing onto the cold tiles.
