Bored and irritated with each other, step-siblings Michelle and her brother find themselves alone one afternoon. Michelle retreats to the bathroom, her fingers dancing over her clit, her other hand kneading her full breasts. Her brother walks in, catching her mid-act, and they argue heatedly. Later, they make amends, their shared frustration leading to an intense masturbation session together. Michelle's eyes widen as she takes in her brother's thick, hard cock, and they're both consumed by a desire they can't deny.
