As part of the countermeasures against the declining birthrate, a radical 'practical sex education' is introduced, where teachers teach using their own bodies. A newlywed teacher, though bewildered, begins to offer her body to her students. 'To get pregnant, you must insert an erect male organ into the female organ on a fertile day and ejaculate toward the uterus. Watch closely how I get pregnant.'




















Actress: Ian Hanasaki. The premise is very erotic, but I wish they had put more effort into the camerawork.
*As for this series in general, I wonder why they have her hooked up with a male teacher. Everything is ruined. Since it's called "sex education," it should be limited to students only. It's a shame because his acting days were close to his best.
Personally, I didn't really like it... If it's an Ian-chan production, there are plenty of other works that are way more stimulating and worth watching!
*Both the actress and the situation were wonderful. Also, I wanted him to have relationships with multiple male students in the first half of the class. That's just a shame. I think I've done a lot of things, like the guy who cums too hard and ejaculates too quickly, and the guy who tried to put into practice what he'd learned from erotic videos and was scolded for it.
A newlywed teacher is forced to take on a hands-on sex education class because there's no one else qualified. Despite being well-prepared, she hesitates until the last moment, but once she enters the classroom for her first lesson, she shakes off her doubts and puts on a calm facade. I was moved from the start by how brightly and seriously she engages with her students. Three students in a classroom feels a bit sparse, but Chapter 1 covers everything from the first lesson—where Ms. Hanasaki gets pregnant by one of the students—until she goes on maternity leave. During the practical session, she takes her time with every stage of foreplay, giving detailed instructions from a woman's perspective on what the boys should be mindful of. She explains intercourse at length, switching through various positions. It's cute how she tries to objectively convey even her own pleasure to the students as part of the lesson. The class goes well over an hour. Since they couldn't take a break without interrupting the flow, I assume it was a two-period special session. Chapter 2 is the second sex education class, set two years later. It's Ms. Hanasaki's first class back after giving birth, but personally, it felt like an unnecessary addition. This chapter features a male head teacher as her partner, and the sex is between the teachers, with the three students just watching. This time, various toys are introduced, and the content shifts to a male perspective. When Ms. Hanasaki, pregnant again six weeks later, comes to inform the head teacher about her maternity leave, he tries to claim paternity, but she firmly refuses. It’s an interesting callback to her reason for forbidding the male student from the first chapter from seeing her again. The production's commitment to the title 'Danger Day' is conscientious and commendable. Many other works with 'Danger Day' in the title have nothing to do with it at all. However, while the chance of pregnancy from unprotected sex on a 'danger day' is far from 100%, I suppose the 100% success rate is a necessary narrative convenience. Or is it? A story where she fails to conceive a few times before finally getting pregnant would be more realistic. Plus, it would allow for scenes of her having sex with a different student each month until she conceives, which would be more engaging—and perhaps more 'educational' for the students, right? If there were female students in the class, what kind of sex education would that be? Would it just end with showing them the act as a model? You can't get a female student pregnant, and if you teach contraception, wouldn't that contradict the goal of addressing the declining birthrate?
