In the sultry, humid air of a packed Saigon gym, a young, straight Vietnamese boy, clad only in tight, sweat-soaked shorts, can't resist the urge to tend to his throbbing cock. Slipping into a secluded corner, he tugs at his bulge, feeling the heat and friction of his own touch. His breath hitches as he pulls out his stiff, veiny dick, the cool air a stark contrast to the warmth of his palm, as he jerks off in the dimly lit, echoing gym, seeking a quick, discreet release.
