Natsuki Kisaragi is a slightly busty beautiful girl who loves traveling, and her sex motto is "The school trip isn't over until you get home"—she enjoys thorough aftercare as part of the experience. Her sexual preference is openly masochistic; she absolutely loves spanking and choking. The highlight is watching her delighted expressions while dominating her thoroughly during sex. In alternate scenarios, she also enjoys training-style play and indulges in threesomes. Her dynamic responses and adaptability throughout the play are one of her main charms.
