In a steamy, close-up homemade masterclass, Cocknveins17 explores the limits of pleasure and pain. The challenge? To keep his massive, uncut cock erect and throbbing while wearing a tight, restricting expander panty. His fingers dance along his hard length, tracing the sensitive veins, his breath hitching as he fights the urge to cum too soon. His cock, a deep, vein-ridged purple, strains against the black fabric, the outline obscene. He moans, his body writhing, his cock leaking pre-cum as he brings himself to the brink, over and over. Finally, with a guttural groan, he can't hold back any longer, his cock pulsing, his cum leaking out, a sticky, wet mess on his stomach.
