The boys, their inhibitions lowered by the thrill of secrecy, engage in a wild masturbation session. They start by rubbing their bulges through their jock straps, their eyes gleaming with desire. Zack, the most adventurous, pulls out his throbbing cock first, stroking it slowly while watching Casey and his friend. Casey, unable to resist, follows suit, his hand flying over his sensitive flesh. Their friend, hesitant at first, eventually joins in, his cock standing proudly erect. They play with each other's balls, their hands slick with precum, before they all explode in a chorus of groans, their cum splattering onto the floor.
