DESCRIPTION
``If you teach me how to study, I'll teach you naughty things in return.'' A private lesson in exchange between my sister-in-law, who is so slutty that her grades are disastrous, and me, a virgin who is obsessed with studying.
One day, my sister-in-law, who had never studied at all, suddenly announced, ``I'm going to university!'' At my mother-in-law's request, I decided to teach her... This is impossible! I can't do it! My sister-in-law is so stupid that I give up. However, the stepsister says that she will teach him naughty things if he helps her study... I'm a hard worker and good at studying, and my sister-in-law is a slut, so she's good at sex... Result: Win-win equivalent exchange established! The secret private lesson begins!

これまで全然勉強をしてこなかった義妹がある日突然「大学に行く！」と言い出した。義母のお願いでボクが教えることになったのだが…。これは無理だ！出来なさすぎ！あまりにもアホな義妹に早くも諦めるボク。ところが義妹は勉強を教えてくれたらエッチなことを教えてあげると言い出すのだ…。ボクはガリ勉で勉強が得意、義妹はヤリマンなのでセックスが得意…。結果…互いにWinwinの等価交換成立！で秘密の個人授業開始！
그동안 전혀 공부를 하지 않았던 여동생이 어느 날 갑자기 '대학에 간다!'라고 말했다. 장모의 부탁으로 나가 가르치게 되었지만… 이것은 무리입니다! 너무 할 수 없어! 너무 바보 같은 여동생에게 일찍 포기하는 나. 그런데 의 여동생은 공부를 가르쳐 주면 야한 것을 가르쳐 준다고 말하는 것이다. 나는 갈리 공부로 공부가 자랑, 여동생은 야리만이므로 섹스가 자랑… 결과… 서로 Winwin의 등가 교환 성립! 에서 비밀 개인 수업 시작!
