In a cramped, dimly lit bathroom, Michelle and her stepbrother find themselves alone and restless. Michelle's fingers dance over her clit, her other hand squeezing her full breasts. Her stepbrother, hearing her soft moans, barges in, catching her mid-act. They clash, but later, curiosity and desire take over. Naked, they explore each other's bodies, Michelle's eyes widening at her brother's thick, throbbing cock. She imagines it stretching her tight pussy, but their intimate moment is cut short by an unexpected intrusion.
