In the throes of boredom, Michelle and her stepbrother find themselves alone and horny. Michelle retreats to the bathroom, her fingers exploring her wetness as she strokes her curves. Caught in the act, they argue, but later, naked and aroused, they masturbate openly in front of each other. Michelle's eyes widen at the sight of her stepbrother's massive cock, and she fantasizes about it filling her. Just as they're about to act on their desires, an intruder forces them to abruptly stop.
