Starting right where we left off—the stunning, big-breasted dentist Mizuki Yume appears on the scene. As she quickly puts her patient to sleep and begins a cleaning, her massive breasts press heavily against the patient's forehead, their soft, jiggling motion impossible to ignore. Feeling her bouncing tits, the patient struggles to maintain composure, desperately focusing on factoring quadratic equations in his mind—but before he knows it, his cock is rock hard. Unable to resist any longer, he tears open Yume's white coat, groping her lush breasts before finally stuffing his cock firmly between them.
