TSUKINOE SUI, already experienced in orgasming through the Spence tail area of her breasts, joins the popular clinic series devoted to developing this newly explored erogenous zone. A specialist massages the so-called G-spot of her breasts, making her instantly aroused and sending her arching into convulsive breast orgasms. Teasing nipple play during sex has her screaming and squirting heavily; toy-induced orgasms leave her knees shaking as she loses bladder control. Her breasts become so sensitive that she cums while titfucking, and the nipple-focused finale triggers her most explosive squirting orgasms yet.
