The showerhead pours a cascade of water, creating a slick canvas for the masseuse's roaming hands. The recipient squirms, their body tensing and relaxing in rhythm with the kneading fingers. The masseuse's breath hitches as they reach the edge of their client's ass, the skin glistening and inviting. They lean in, their tongue flicking out, tasting the water and sweat, before diving in, their face buried between the cheeks, their tongue delving deep, the recipient's cries echoing off the bathroom walls.
