Under strict rules of "no backtalk," "obedience to commands," and "mandatory cleanup blowjob," this is a sexual education documentary focused on molding a proper 'obedient M girl' by engraving male pleasure into her body. The fourth student is "Nanami," a quiet, introverted girl with a slender, soft build measuring 156cm tall, B78 W60 H87, and having had only one prior sexual experience. Her first impression is that of someone who has lost their emotions somewhere—she smiles, yet her reactions feel distant, fitting the classic "introvert" type. Nanami keeps telling herself: "If I feel pleasure, I lose. If I enjoy it, I'm ruined." She believes that since she's only doing this unwillingly, her heart remains pure. During sex, she bites her lips tightly, suppressing any sounds, remaining silent and reserved. Her pitiful resilience might move one to tears, but it's merely a delusion—she's just an insatiable pervert at heart. Tell me, could there really be a girl who hates giving blowjobs yet drips so much horny juice from her slit that it forms visible strings? When asked about marriage, Nanami replies, "Not at all. I'd rather stay alone forever." That kind of statement sounds like something only a leopard-print-clad woman with three divorces under her belt, fully experienced in men's hearts and bodies, would say. "I don't really need friends either." Sure, such people exist. I won't deny that. But in your case, aren't you just trying to justify a lonely school life? Friends add color to life. As rehabilitation, you can start by being sex friends with me. Just meet up whenever you feel horny. It's very low-pressure, the perfect arrangement. Using such sophistry, I ended up giving her a creampie anyway.
