Rex, a straight-laced jock, finds himself in a locker room filled with gay porn. He scoffs, "As a joke, I'll watch this." But as he watches twink boys moan and writhe, his straight cock stirs, betraying his amusement. He tries to laugh it off, but the sight of their smooth bodies and throbbing dicks keeps him hard. He reaches down, stroking his own cock, laughing nervously. "Just a joke," he mutters, but his grip tightens, his strokes speed up. He's no longer laughing when he cums, thick ropes splattering onto the floor, a straight boy's load for gay porn.
