A man who continuously pursues his own G-spot stimulation techniques chooses the esthetic salon he runs as the place to demonstrate his research results. Shy office ladies follow his instructions and receive massages in lewd positions. Under his skillful touch, their will to resist vanishes completely, as they are enveloped in expert-level pleasure one after another. Screaming, "I'm cumming! I'm cumming already...!" they are pulled into an endless orgasmic hell. Their bodies convulse continuously from the intense pleasure, and their passionate expressions become the highlight of the video. (Yotsuya Eizo) ※Facial exposure in main feature
