"Joss, a devout girl, struggles with her lust for her stepbrother Sam. Their late-night encounters in the bathroom always end in sin. Tonight, Sam, already naked, waits for her, his cock throbbing. Joss enters, her eyes locked on his hardness. She can't resist, her pussy dripping as she squats, letting her piss soak the floor. She looks up at Sam, their eyes meeting as they both let go, their bodies shaking with pleasure and shame, their fluids creating a lewd, slippery mess on the tiles."
