His father, who had worked hard on his poorly studied son Toor, decided to ask for a tutor from his friend's wife, Mitsuki. However, I don't want to study because I care about the big breasts and sexy dominance body of Mitsuki. Mitsuki responds to Tool's H-like request under the exchange condition of focusing on studying... Mitsuki was a Doskebe tutor who used his own body to teach me anything that was dirty!
