In a dimly lit room, a couple indulges in their kink. He, bound and helpless, watches as she teases his cock and balls, slapping them gently, making him wince and moan. She laughs, a sound of pure pleasure, before taking his cock in her mouth, sucking him off while still slapping his balls. He tenses, the mix of pain and pleasure overwhelming. When she finally unbinds him, he takes control, flipping her over, slapping her ass and pussy, making her beg for more before fucking her hard and rough.
