In the dim light of the closet, Michelle's natural tits rise and fall with her breath as she watches her brother's cock grow harder by the second. She can't help but reach out, wrapping her small hand around his thickness. He groans, pushing his hips forward, urging her on. She strokes him faster, feeling his precum drip onto her fingers. He can't take it anymore, pushing her back onto the bed and spreading her legs. Her pussy glistens, inviting him in. He slides his cock inside, feeling her tightness envelop him. They move together, their bodies slapping against each other, their moans filling the closet until they both reach their peak, collapsing in a sweaty, satisfied heap.
