Michelle and her stepbrother, confined to a tiny bathroom, find themselves alone and helplessly aroused. Michelle, her pussy throbbing, fingers herself, imagining her brother's thick cock stretching her tight hole. He catches her, his eyes widening at her naked, wanton form. They argue, but the tension is palpable. Soon, they're entwined, Michelle's wetness coating his cock as they dry hump, their clothes a futile barrier. Just as they're about to cross the line, a knock at the door forces them apart, leaving them breathless and frustrated.
