In the sanctity of his room, a curious teen explores his newfound desires, his small cock throbbing in his hand. But when his horny sister barges in, she's not content to let him play alone. She straddles him, her tight teen pussy grinding on his lap as she teases him with her perverted demands. 'You're going to fuck me, little brother,' she purrs, her big tits heaving. He hesitates, but her sultry voice and wet pussy convince him to give in, his small cock eagerly thrusting into her, stretching her virgin hole.
