After a heated argument, they retreat to their rooms, but Michelle's masturbation session is cut short when her brother catches her. Instead of anger, they share a look of mutual desire. Naked, they explore each other's bodies, Michelle's fingers tracing her brother's thick, straight cock as he jerks off. Their lust grows, and Michelle fantasizes about that massive dick inside her. Just as they're about to cross the final line, an intruder forces them to pause their taboo dance.
