My senior, Nanaha Kinouchi, is a beautiful woman with big breasts and a great figure, who also does her job perfectly, she's a person without a single flaw except looking down on me. Nanaha-san always makes fun of me. I think such a power harassment attitude is absolutely wrong... But maybe I'm the one who's really crazy because I get so excited by her senior's attitude. What kind of face will Nanaha-san make when having sex with a man? Will she have a sweet face? Will she be surprisingly M? But will she still be a slut? Ah, I can't do this anymore, I'm too full of thoughts. Let's force her to commit to find the answer. I'll make her feel a lot better, okay, senior...,
