Step-siblings Michelle and her brother, both restless and pent up, find themselves alone and horny. Michelle retreats to the bathroom, her fingers dancing over her wet clit, her big ass pressing against the tiles. Her brother, catching her mid-act, bursts in, his thick, straight cock tenting his towel. They argue, Michelle's anger fueled by her arousal. Later, they make amends, masturbating openly in front of each other. Michelle, eyes locked on her brother's massive cock, imagines it filling her tight pussy. Just as they're about to act on their mutual desire, an intruder forces them apart.
