Trapped in his room, this horny brother indulges in forbidden thoughts of his sister, her luscious body and the taboo lust that passes between them. He jerks off furiously, his cock throbbing in his hand, imagining her riding him, her tits bouncing, as he grips her hips and pulls her down onto his hard cock. With a guttural groan, he comes undone, spilling his load onto the floor, wishing it were his sister's body instead.
