Barging into the bathroom, the stepfather finds his sister dripping wet, just out of the shower. Seizing the moment, he pushes her against the wall, rubbing his throbbing cock against her ass. She moans, spreading her legs as he fingers her hairy pussy, feeling her squirt onto his hand. He thrusts into her, fucking her hard until he can't hold back, pulling out to cum all over her back. She turns, rubbing his cum into her skin, then sinks to her knees, licking his cock clean.
