Shion belongs to the badminton club and injures her leg during practice, prompting her to visit a well-known local sports chiropractic clinic for treatment. During her first session, the chiropractor's unsettling gaze makes her uneasy, and as the massage progresses, his hands begin to naturally wander to her chest and waist. Shion, being naturally timid, finds herself unable to resist, and the situation quickly escalates. Her young, sensitive body reacts intensely to the stimulation, arousal building within her. The chiropractor's warm hands and powerful massage gradually shake her resolve, until she can no longer turn back.
