Michelle and her stepbrother, left alone and bored, find solace in self-pleasure. Michelle's moans echo through the bathroom as she fingers her wet pussy, her stepbrother's eyes widening at the sight of her large, bouncing breasts.

As they're about to give in to their taboo desires, an interruption forces them apart.
