Nanako, who was kidnapped just because she was cute. She is a pure and quiet-looking girl. Nanako-chan will then undergo training by Mr. Natsuki. She is restrained in a standing back position and her ass pussy is thoroughly tormented with fingers. Then, while convulsing her legs, she drips a lewd juice from the tip of her clit and, saying "I'm cumming! I'm cumming!", she finishes in an instant. It seems that the door to the "dom" that was sleeping deep inside her has been opened. After that, she undergoes training by Mr. Natsuki, changing methods and items, such as one-legged restraint, lying flat, and M-shaped restraint, and throughout the process, she makes her clit erect and arches her body, rolling her eyes and saying "I'm cumming!! I'm cumming!! Please make me cum!!!", and in the end, she begs herself to reach climax, "Nanako" was.
