Young track and field athlete Yamakado visits an esthetic salon to relieve the fatigue from his club activities. After completing the consultation and changing into treatment underwear, he finds himself surprised to be wearing pants that leave his lower body completely exposed. Beginning the massage with foot therapy, the sensation feels pleasant and gradually lowers his guard. However, the treatment slowly shifts in unexpected directions. Labeled as a full-body massage course, Yamakado continues despite subtle discomfort, surrendering himself to the pleasurable sensations. As the session progresses, he gradually yields his body entirely. Ultimately, the therapist uses their own body to perform anal massage on his ass. Caught in this unexpected sequence, Yamakado feels both shock and confusion, yet simultaneously accepts it as a new experience. Facial exposure is included in the main footage.
