A brother and sister find themselves sharing a bathroom, the air thick with unsaid words. She begins her shower, the steam filling the room, her body visible through the frosted glass. He watches, his cock hardening at the sight of her soapy hands caressing her skin. She turns, her eyes meeting his, a challenge in her gaze. She spreads her legs, her fingers finding her clit, her moans filling the room. He can't help but join in, his hand stroking his cock. She steps out, water cascading down her body, and takes him in her mouth, her tits pressing against his thighs. He grabs her hair, fucking her mouth until he can't hold back anymore, pulling out to cum all over her face.
