A muscular, tattooed prisoner takes charge in the cramped, dim cell, pushing an eager young jock against the cold, hard wall. The inmate grinds his massive, uncut cock against the jock's firm ass, making him moan in anticipation. The prisoner spits on his hand, lubing up, then plunges his thick rod into the jock's tight, virgin hole. The jock gasps, clutching the wall as the inmate begins a relentless, pounding rhythm, his heavy balls slapping against the jock's ass. The cell fills with the sound of their bodies meeting, the jock's moans, and the inmate's grunts of pleasure. The jock's own hard cock bobs with each thrust, leaking pre-cum onto the filthy floor. The inmate builds to a crescendo, fucking the jock harder and faster, until he pulls out and covers the jock's back with thick, ropey streams of cum.
