So let us start off with a synopsis first. The main character is Hana Natori. She is a 25 year old girl and she is pretty much accomplished in life. But one day, she takes on a request from her aunt because she is too obedient and can not say no. Her cousin, Kaho Miyoshi, refuses to attend high school so she has to step in as her! Yup, she has to pretend to be her cousin so that she can magically graduate high school without having to go! How will Hana Natori pass as a high school student? Well, she looks really young and she is practically identical to her cousin Miyoshi. So she was ready to take on this mission. She was ready to go back to high school, I mean how hard can it be right? But luck runs out fast. On her first day of school, she has world history class and the teacher was no other than her old classmate from when she was in high school for real! His name is Okito Kanie. Of course, he would recognize her anywhere. She knew her cover is blown and that he will reveal her secret. So, when they met up she was ready to tell her aunt that she will not be able to do this anymore but then Okito Kanie kisses her and makes more moves on her – then she knows that she is about to be blackmailed. She takes it and lets him do all the sexual stuff on her, just so she will not disappoint her aunt.

For animation reviews, this was has pretty great animation. The characters look close to real life. They have sharp features, every feature is also very detailed which makes them look like real people. And if you are new to the hentai porn series thing, these types of animation will get you hard and horny because it is close to real porn but not real still. If that makes any sense. The color grading of the series is also nice. It is light yet colorful and very pleasing and “fresh” to the eyes. Which is a good thing for us because it is easy to watch and not to mention that each episode lasts for just 6 minutes each. A very easy watch. The series is also a censored one but the sex scenes and the build ups make up for you seeing a blurred vagina or penis. The build ups create tension and the foreplay is very hot it is enough for you to start fapping out. And then the actual sex is there, the positions are animated beautifully. There are a lot of doggy style sex scenes and the animation of that must be pretty hard – and in this hentai porn series they make it look really great. So great, you feel as if you are also getting fucked that way.

Let us talk about sound effects and voice acting now. Well, we usually say this in reviews but it is good. Maybe so-so. If there is nothing out of the ordinary then we can not really say it is amazing. But there are all the elements needed there. Sex sound effects are on point, which they need to be to match the great animation. Voice acting is also good. The actors and actresses captured each and every emotion they have for their characters. And like we said, these characters have personality and that shows up through the voice acting. So these effects and acting blend well with the whole hentai porn series.

Overall, when you put the storyline, the animation, the sound effects, and the voice acting together – it is a pretty great hentai porn series. If you can look past the blackmail and rape themes, then you will enjoy it. If you are not much for a great and deep story, then you will like this. The animation, sound effects, and voice acting are amazing over all and this saves the whole fact that the story is so-so or nothing extraordinary. But yes, we recommend you watch it still. It has short episodes and it has twelve so it is an easy peasy watch. So it is not really a waste of time, what is six minutes a day that will also get you horny. Pretty great.
