A twink, eager to tease, slips into a snug jockstrap, his bulge straining against the fabric. He strokes his thick, uncut cock through the material, pre-cum soaking the stretchy cloth. With a grunt, he pulls out his throbbing dick, balls heavy and low, and jerks off vigorously. Cum erupts, splattering his abs and the jockstrap, leaving it dripping and used.
