In the privacy of his room, a horny teen indulges in a marathon masturbation session. He starts by teasing his nipples, pinching and rolling them until they're hard. Then, he moves to his cock, stroking it slowly, building up the anticipation. He grabs a bottle of lube and coats his cock, then reaches behind to slick up his asshole. With a deep breath, he slides a finger in, then another, scissoring them to stretch himself open. He replaces his fingers with his cock, fucking himself slowly, then picking up the pace until he's slamming into himself, his body shaking with each thrust. He comes with a loud groan, his ass still clenching around his cock.
