Ikumonogakari The Animation

Imagine someone wakes up in the morning and comes up with idea of a group sex school hentai which there are literally no feelings between any of the characters. They just sex in groups with random girl classmates. It looked like to me girls have some kind of responsibility to satisfy boys. I mean what the? Are you serious? Boys are only using their random classmates.
It might not look like it, but this is one of the worst hentai in my life. The only good thing about is the art is acceptable. It sucks in every other aspect.
I can say it is worse than NUR ... studio hentai. They have a (appealing) plot, but that doesn't exist here at all!

Also check my profile for some good hentai not these kind of sick non-senses.

This hentai is pedo bait, there's no other way to put it. The uniforms worn by the characters are stereotipically those worn by Japanese middle schoolers. There's not even a story to consider, just senseless sex between characters that might as well be nameless, and there's a fair bit of non-consensual acts depicted (without warning from the show, the poster or the synopsis, mind you) despite the supposed excuse for what happens in the story being extreme sex-ed lessons. The art is better than many other hentai and even some random shows. but it's wasted on this ridiculous and pointless show.

TL;DR gang bang fans only.

One of the few times I've seen a hentai put so little effort into a story. From start to finish it hops from one gang bang scene to another with us knowing nothing other than some names and positions (like class president) of the people involved. The story seems to loosely follow a free use sex school or something along the lines of sex education. If you really like gang bangs though and want nothing else in your hentai, then this one is perfect for you. The animation and art are fairly good quality and there is a good mix of ... location and a little mix of girls and sex positions to change things up from scene to scene. If you want even a hint of story, character depth, or sex not involving multiple guys; then this is definitely not the hentai for you.

They said school will teach you about sex, but this is just ridiculous! *Canned Laughter*
Jokes aside, I wouldn't recommend people watch this; the guys in the class tend to overpower the girls and ignore how they want to be treated, which is an awful thing that's even worse when the teacher is right there and does nothing about it. Doubly so with how there's only a male teacher and no female counterpart in sight. I get that it's 'hentai logic' or whatever, but if the point of this is to educate about sex, then maybe have the characters respect the fact that no means no.
Because ... of this and the fact the characters still look fairly young, this hentai gave me bad vibes all around and I'd be wary of people who actually would say that they enjoyed it.
