Rōnin Kenji asks his highly educated sister-in-law, Asami, to teach him exam tips. Kenji, who has been focused solely on studying and hasn't had much interaction with women, finds Asami's beauty too stimulating. Just sitting next to her makes it impossible for him to concentrate. Asami, seeing Kenji struggling to focus, says, 'I'll teach you more than just studying.' The perfect sister-in-law, both in looks and personality, takes Kenji's erection into her best vagina as many times as he can get hard! A dream come true for a virgin!
