Fucking a big tits neighbor who craves a big cock

Hinata Koizumi is the female manager of a baseball club. She works in an all-male environment, especially since there is a rather strict faculty advisor here. Hinata makes a big mistake and is at risk of losing her job; the faculty advisor calls her to the office and expresses his desire to fire her. Hinata, of course, pleads for her job, and he exchanges this for a request that Hinata must provide sexual services for him; he wants to educate her about sex. Out of fear of losing her job, Hinata follows all the demands of this strict teacher.
