In the throes of self-imposed bondage, this eager slave indulges in a no-holds-barred solo session. Gently probing his prostate, he grimaces and moans, reveling in the exquisite torture. A single drop of precum pearls at his slit, and he can't resist the urge to milk it out. As his excitement builds, he allows himself the forbidden pleasure of urinating mid-masturbation, the warmth adding an illicit thrill. In the final act of his self-denial, he teeters on the edge, hands away from his aching cock, until his body convulses in a powerful, hands-free orgasm.
