Tengyuan's sports team dorm is buzzing with discreet pleasure. In separate corners, teammates stroke their cocks, bare and exposed, believing they're alone. Tengyuan, the hidden camera operator, captures the illicit scene. One by one, they explode, semen splattering their chests and abs, their moans barely muffled. The room fills with the scent of sex and sweat as they catch their breath, unaware of the explicit evidence left behind.
