Mark Carroll, a proud and confident gay man, finds himself in a locker room challenge. His opponents, jealous of his big dick, dare him to jerk off until he cums. Mark, never one to back down from a challenge, accepts. He strips off his clothing, revealing his massive, throbbing cock. He strokes it, his hand moving up and down the length, his balls tight and heavy. The room fills with the sound of his wet, eager strokes, and the smell of his musky, manly scent. He grunts, his body tense, and finally, he cums. His cock pulses, sending stream after stream of hot, sticky cum onto the floor.
