Dango-sensei has just been appointed to a certain school. When he arrives at his classroom early in the morning, he finds Otsuki-sensei, the health teacher, tormenting the male students in an erotic way. Yes, this school is mentally controlled by one perverted female teacher... Hibiki-sensei, who loves to thoroughly explore sex, checks men's dicks every day under the guise of a health check. She's a pervert who gets excited by unusual situations. Her erogenous zones are her nipples and clitoris. In fact, she can be both a slut and a masochist. "What a shameless thing to do so early in the morning!" "This is part of the medical examination. It's a given for a health teacher." "This school is in ruins! Education is in ruins! It's deplorable!" "Vice Principal, please don't get so worked up. Maybe you're not getting enough calcium?" "That's not true!" 「Really? Let's do a quick check-up." "What are you talking about...ahhh!" Hibiki-sensei kisses the vice principal and covers his mouth. And then the sex begins. The vice principal, who has become completely obsessed with Hibiki-sensei, is proposed a threesome with the head of the grade, Tamura-sensei (already Hibiki-sensei's obedient dog). Just being touched makes Hibiki-sensei twitch. Eventually she is stripped naked and her crotch is stimulated with a toy, bringing her to multiple orgasms. This time, Hibiki-sensei strikes back by caressing her whole body, licking, giving her a blowjob, and giving her a handjob. She looks at his instantly erect penis with a smile of delight, and seduces him as she inserts it. "Let's cum inside and check his health," and a big squirt comes! The vice principal thinks. "My life as a teacher is rosy!" Lots of POV footage! Why don't you try being teased by Hibiya-sensei too?
