Emi is a sheltered girl living in an upscale residential area of Tokyo. Her father is an interior designer, and she has grown up without any hardships, developing an honest and curious personality. While waiting to meet a friend, she is skillfully lured away with smooth talk and taken to a cafe. As her tension begins to ease, she's led to the restroom where her D-cup breasts are gently caressed before a vibrator is inserted. She's then taken to a warehouse somewhere in Tokyo. Though nervous from the first-time experience, she becomes enveloped in both thrill and pleasure.
