The amateur jock's body, a canvas of sweat and cum, reflects the raw, primal nature of his masturbation. His beefy hands grip his mammoth cock, veins bulging as he jerks it furiously. The room fills with the wet, slapping sounds of his self-pleasure, his grunts of pleasure echoing. He uses both hands, one stroking his cock, the other playing with his heavy balls, pushing them up and out of their sac. His body tenses, and he unleashes a torrent of cum, coating his fist and dribbling down his shaft, the sight of his jizz-drenched cock pushing him into another round of intense stroking.
