Hinako, an office worker, lives with her boyfriend Atsuro. One day, she sprains her ankle and, at Atsuro's suggestion, calls a dispatched masseuse. The masseuse arrives and massages Hinako, and she suddenly feels something when he massages her sensitive spots. Even though she knows she shouldn't, Hinako secretly gets excited and starts looking forward to the massage. After several massages, she is teased to the brink of orgasm, and the timer goes off, signaling the end of the time. When he asks, "Do you want to extend?", Hinako nods.
