In the privacy of his room, Billy gives in to his carnal cravings. He starts by teasing his nipples, pinching them until they're hard peaks. Then, he moves down, wrapping his hand around his aching cock, pumping it eagerly. He's so turned on, he can't help but moan, his body writhing as he pleasures himself. He kneels on the bed, ass in the air, and slips a finger into his tight hole, imagining it's someone else's cock filling him. He fucks himself with his finger, his strokes on his cock becoming frantic. With a loud groan, he comes, his cum painting his sheets.
