Kumi and her brother are trapped in a closet, their bodies pressed together as they try to keep quiet. The heat of their bodies and the tension of their situation cause their breath to grow ragged. Kumi can feel her brother's cock growing hard against her, and she can't help but imagine what it would feel like to have it inside of her. Her brother's hands grip her hips, and she can feel the heat of his breath on her neck. The two of them struggle to maintain control, but it's clear that their bodies have other plans.
