In the steaming bathroom, a brother and sister find solace in their shared isolation. She slips into the tub, her body glistening under the water, fingers exploring her secret folds. He enters, startled by her naked form, but his gaze lingers, drawn to her curves. They argue, tension thick in the air, but soon, their eyes meet, and the argument fades. Naked, she takes him in, his cock hardening at her appreciative gaze. They step closer, breaths heavy, when a sudden noise outside shatters the moment.
