Soft perm and a baby face with a raccoon-like appearance. The new teacher, Mr. Yui, has an irresistible look with his droopy eyes that's a hit with the guys. Today is our all-boys school's sex education class. 'Do I have to do this too...' It's tradition for new teachers at our school. Hesitantly, he begins measuring the students' bodies and erections. Hey! Who said to jerk off until they cum? The teacher will measure three sizes too. We'll also measure the vaginal opening. 'No, don't look...' Do you always secrete this much fluid? Don't hide it. This is for learning. Alright, next up is coitus practice to distinguish between boys and girls. 'Huh? Sex? That's...' What? Are you abandoning your students? Then why are you leaking this much from your nipples and hand jobs? 'I've never done that before...' You're lying (laughs) How does it feel when it comes out? A little nice? It's more than just a little! Apologize. Did you lie again? After punishment blowjobs, deep thrusting from behind! For girls, it's about two or three days before ovulation. For boys, it's deep penetration and ejaculation inside! 'It's being thrust deep inside' 'The penis is all the way inside the vagina' 'It's near the cervix' 'It feels weird. Everyone, I'm sorry...' Sorry? You mean you're apologizing, right! You can't understand with just a weird feeling. That way, you won't be able to write it on the test! 'I-I'm about to cum. It's an orgasm...' Students enjoy the warm insides of the vagina while being spanked in a reverse cowgirl position. They cum over and over with troubled expressions! But I have to explain it properly to the students. Every time, they get wet and reach orgasm! Mr. Yui seems to have a perverted tendency! 'I-I want a boy...' For Mr. Yui, who says this, deep penetration and ejaculation inside, making her feel satisfied.
