In the shared bathroom, siblings eagerly strip, the scent of soap filling the air. The brother's eyes linger on his sister's smooth, shaved pussy as she steps into the shower, water cascading over her curves. She catches him watching, a smirk playing on her lips. He joins her, their bodies pressed close in the cramped space, hands exploring slick, soapy skin. His cock hardens against her thigh, her breath hitches as she feels it. Their lips meet, tongues tangling, as they succumb to the steamy, taboo temptation.
