Trapped in the bathroom, the horny amateur can no longer contain his five-day semen buildup. His massive, veiny cock strains against his tight undies, the outline of his perfect, big balls visible through the thin fabric. He locks the door, eager to unleash his pent-up lust. He strips naked, revealing his thick, throbbing erection, and begins a slow, teasing handjob. His big balls sway and bounce as he strokes, the anticipation of release driving him wild. Precum leaks from his slit, and his breath hitches as he edges closer to climax.
