This role-play is performed by adults. A problem child with no desire to study. When I was irritated by her lack of motivation, she provoked me in an extremely erotic way, saying, ``If you can resist cumming on me, I'll teach you!'' Lately, I have been enduring this interference every time I teach! But today, a female student plays with me and says, ``If you make me cum, I'll study!'' Finally [the one who cums loses! ] A sex battle breaks out! While enduring the student's amazing techniques, I also fight back with my hands and dick! Kochitora has a strong will as an adult, so I can't lose!
