The best female teachers (Yui, Ichika, Marie) are tricked by men into becoming sex slaves who are willing to do anything, including raw sex! They serve with their mouths! They give continuous blowjobs! They're tied to desks and repeatedly penetrated and creampied! Then, a speculum is inserted into their pussies and the students' semen is poured into them! There's no future for these female teachers who have become mere sex toys!
