In the throes of a vigorous workout, a ripped jock hears a knock at his door. A hunky fireman stands outside, his uniform straining against his muscular frame. Inviting him in, the jock leads him to the bedroom, his eyes locked on the fireman's crotch. Bending over, he presents his ass, and the fireman, unable to resist, fingers the jock's hole, lubing it up. He then slides in his massive cock, making the jock gasp. The fireman grips the jock's hips, pounding him hard, his balls slapping against the jock's ass. The jock jerks off, his body tensing as he nears climax. The fireman, feeling the jock's ass tighten around his cock, fucks him harder, his breath coming in ragged gasps. The jock erupts, cum flying across the room, and the fireman follows, filling the jock's ass with his hot, thick load.
