Uninhibited and alone, the muscular man takes his time exploring his own body, tracing the lines of his well-defined muscles with his calloused hands. He teases his sensitive nipples, pinching and rolling them between his fingers before moving lower, grasping his throbbing cock with a confident grip. His breathing deepens as he pumps his hips, fucking his fist with increasing urgency, until his body tenses and he lets out a guttural moan, releasing his pent-up load.
