Natsuki Kisaragi picks up a flyer for a free massage she happened to see and, due to ongoing lack of sex with her husband, decides to give it a try. The masseur carefully strokes every part of her body, making her writhe with pleasure. Unfulfilled by masturbation alone, she books another session. Her arousal grows uncontrollable, and she begins craving the masseur's cock. Deeply addicted to the massages, Natsuki quickly reserves another appointment. This time, she's flustered when an assistant joins, but cleverly turns the situation to her advantage, ending up enjoying a threesome.
