The hot pervy step brother couldn't resist watching his step sister shower. He peeked through the door, his cock hardening as he admired her wet, naked body. Unable to control himself, he burst in, surprising her. She was shocked but turned on. He pushed her against the wall, lifting her leg and shoving his cock into her tight pussy. They fucked hard and fast, both moaning in pleasure, their quickie ending in explosive orgasms before anyone caught them.
