[Chinese]SSIS-845 Her younger sister, whose breasts have developed into those of an adult, is overly interested in 'SEX' after learning about it at school and innocently makes me horny! Anzaki Yuuri

When she came to my house to play, her younger sister Yurika, who had come with her, was very interested in 'sexual intercourse' as taught in class. Such a Yurika, however, only had one thing going for her: incredibly large breasts that would even surprise adults. However, she is oblivious to the allure of her own body and innocently tries to seduce me using her breasts just so she can experience 'sexual intercourse'... Eventually, after crossing that line, she started coming to my house regularly to demand 'the act of pleasurable SEX'...
