MIDA-351 A female teacher in a public toilet is a flesh masturbator for all the male students. "Just once..." A delinquent student who was causing class chaos told a new female teacher that she would become more serious if she showed him her breasts. She took this seriously, and ended up being gang-raped and turned into a flesh toilet. Rio Miyaji

Rio, a new teacher, feels fulfilled in her job, but is worried that her class is on the verge of collapse. One day, she makes up her mind to call the students for a meeting, and they ask her, "If you show me your tits, I'll participate in class, lol." Wanting to prevent the class from falling apart, she shows them her tits...and then, one after another, the naughty students get carried away and gang rape her!! The big-breasted female teacher's oversized breasts are grabbed and she becomes a fleshlight for all the male students!! "Ah... I should have just shown them once..." But it's too late now.
