In a moment of unsupervised boredom, Michelle and her stepbrother find themselves drawn to each other's bodies. Michelle, alone in the bathroom, tentatively explores her own wetness, her fingers dancing over her clit and pussy. Her stepbrother, unaware, bursts in, catching her mid-act. They clash, but later, their shared secret brings them together. Naked, they masturbate openly, Michelle's eyes locked on her stepbrother's thick, hard cock. Just as they're about to cross the line, an intruder forces them apart.
