In a dimly lit prison cell, a lone, muscular black stud can't resist the urge to pleasure himself. He strips off his jumpsuit, revealing a massive, veiny black cock that stands at attention. With a hungry grunt, he starts stroking his meat, his big hand barely able to wrap around its thickness. As he picks up speed, his breathing grows ragged, and his abs tense. The cell echoes with the sound of his hand slapping against his cock until, with a final, powerful stroke, he unleashes a torrent of hot cum, shooting it onto his chest and hand.
