[Basketball Team Ace Yumi] A teenage student and J-beauty with a slender, tall frame and gorgeous legs and breasts. A shaved, athletic-bodied girl skilled in massage and bodywork, who shows sensitive reactions during treatment. Using aphrodisiacs and arousal oils, the tension gradually builds. Includes creampie and bareback sex. Though known in Tokyo as a reputable sports massage parlor, it's actually run by a corrupt masseur. Hidden camera footage is taken during sessions, later used as blackmail to escalate the situation further. During treatment, she reaches orgasm, convulses, and even loses bladder control—erotic responses unfold naturally. Skillful talk intensifies the atmosphere, drawing the athlete deeper into pleasure until she climaxes violently, trembling and shaking uncontrollably. Her body completely undone, she eventually accepts the bold act of full cock insertion. An erotic experience in a unique setting where an athlete's physique meets the masseur's craft.
