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.
