Horned-up and anonymous, a young man boards the late-night train, his hand already sliding down his jeans. He's no amateur, his confident strokes revealing a thick, veiny cock. The rhythmic motion quickens, matching the train's clacking rhythm. His face flushes, eyes squeeze shut as he cums hard, ropes of jizz painting the floor. He wipes himself, zips up, and disembarks, leaving a trail of sticky evidence of his self-pleasure.
