A horny stepsister lures her unsuspecting brother into the shower, her pussy already throbbing with anticipation. As the water cascades over their naked bodies, she guides his hand to her soaking snatch, encouraging him to explore her slippery folds. He tentatively fingers her, rubbing her clit and pushing her towards orgasm. Her moans echo in the steamy cubicle as he continues, his cock hardening against her thigh. She grinds against him, seeking more friction, until she finally shatters, her pussy convulsing around his digits.
