In the steamy bathroom, a sister waits, her pussy throbbing with anticipation. The shower door creaks open, revealing her brother, ready and eager. She spreads her legs, water cascading down her curves, as he steps in, his cock already hard. She guides him, her fingers slipping over his length, before positioning him at her entrance. He thrusts in, her wet pussy enveloping him, as they fuck hard and fast, the shower echoing their moans.
