Kateikyoushi x ** 2 The Animation

A guy is given two mind-controlling collars in a locker room that he can use to abuse his private tutors at his will. Sounds strange? It is.

Recommendation
The erotic scenes themselves are appealing, but everything around them can be improved. If you like the genre and just want to see the "plot", then the hentai is enjoyable, but I wouldn't recommend it to the general public.

Genre: big oppai, mind controll, rape, blow job, boob joob, ...

Story
Masato is harassed by his two private teachers, the Shinjo sisters. Their job is to support him in learning, instead they not only don't help, they interfere with his learning and ... if he complains, he is threatened with violence. They've been bullying him since he was a child. One day, as he desperately thinks about his situation in a clothing store, he is concreted into a changing room. There he meets a mysterious woman: she offers him a way out through revenge. She gives him chokers (receivers) and transmitters. The one wearing the choker can be commanded by the one who owns the transmitter. Even though he is skeptical, he accepts the devices and is determined to try them out.

It's stupid... If someone whispers to me that I should go into a changing room, I definitely won't go in there. If there was an almost naked woman in the changing room trying to make it clear to me that you can control people's minds with the collar she has in her hand, I would definitely have walked away and at least not believed her. Why does he try the choker if he doesn't believe in it himself? ... Furthermore, what is said and the action are not exactly causal. For example, at the beginning the first of the sisters gave him a boob job & blow job (after 6 or 7 min), only for him to force her to do another blow job the next day and say that it was her first (after ~10 min)... Why? Just why? They're not forgetful or anything. I think the author simply forgot about that.
At least these are things that I thought the whole time. The story doesn't seem well thought out to me.

Visuals
The visual looks ok. The body fluids are a bit excessive in quantity. Other than that, it's a classic production by
MediaBank. You can like them, but I don't like them. The animations are fluid, but that would be the only thing I would praise.

Characters
You don't like a character and you don't build a connection with anyone. There is the mc who just wants revenge, but is actually reserved and loses sympathy points for believing the woman in the cabin. The woman in the changing room is just strange, but not important. The two siblings are just antisocial, but not so antisocial that you would think they deserved to be punished like that.

Audio
The voice acting is ok and the music does its job. What bothers me are the sound effects: Why do I hear rubber bands (or something rubbery) when I stretch the skin (e.g. when pulling on the breasts or "plotting")? Am I imagining it?

Eroticism
The "plot" is fine. Appropriate foreplay applies and the genres are also “carried out”. However, the "plot" suffers greatly from all the stuff surrounding it. You don't like the characters and have no connection to them, so we miss the revenge fantasies that make him so horny. The sound effects don't really fit or I have a completely disturbed feeling about them. The strange story makes you question everything... Of course that doesn't do the "plot" any good.
