Volleyball Star Forced into New Training Drills by Coach

Elite student Nanae Matsumoto dedicates herself to becoming a national volleyball athlete. During rigorous training sessions at the gymnasium complex—a place meant for athletic glory—her dedication takes a dark turn when her coach demands she participate in a 'new' training exercise: sexual submission. After accidentally overhearing a secret conversation between him and an unknown party while fetching laundry supplies, the coach spots her eavesdropping. He swiftly silences her by tying up her hands and legs before forcing her into intimate contact with him. To ensure her silence regarding his secrets and their encounter captured on camera and film footage that day, he threatens to expose her private moments online. When Matsumoto initially agrees but later tries to negotiate from his office after promising discretion, the coach produces the damning photos as leverage. Refusing to comply fully, she bolts into the storage room only for him to chase her down and violently rape her there. Her torment doesn't end there; subsequent sessions see Matsumoto subjected to relentless gangbang scenarios where she must pleasure multiple partners simultaneously, engaging in oral sex on them and drinking their cumshot. Her days become literal hell, all because of one accidental glimpse into the coach’s illicit life.
