My Imouto: Koakuma na A-Cup

Once again, the peaceful morning is shattered by a diatribe delivered by a sister to her brother. This is a daily occurrence at the Utsumi household, and the fact that his relationship with his step-sister, Miyu, isn't improving is a cause of anguish for Mitsuru. While she may behave like an angel in the presence of their parents, when they are alone, she's a pure devil.

One day, Mitsuru discovers that Miyu has a complex regarding her bust-size. He unwisely brings it up and she blows up at him. While attempting to restrain the raging Miyu, the two lose their balance and fall. Staring into Miyu's face up close, Mitsuru finds himself drawn by her cute features, the warmth of her body, the peculiar scent of a young girl...

My Imouto Koakuma no A Cup is a vanilla incest hentai about a boy and his younger step-sister. The pictures on MAL (to me anyway) make the girl, Miyu, look a lot younger than she really is as she's only a year or so younger than her step-brother and both of them are in high school.

In the beginning, both Miyu and her brother, Mitsuru, fight a lot and don't get along at all. Both of them have feelings for each other that they are keeping hidden. Miyu is also afraid that her brother won't like her because her breasts are small. This leads to her ... buying things to help her breasts grow, but Mitsuru one day discovers a box that is addressed to him full of things for Miyu. Once Mitsuru realizes that Miyu is trying to make her breasts larger so that he will like her, he finally makes his move on her. From there, their relationship becomes more than that of normal step-siblings.

The sex scenes in this hentai are good overall and aren't too short despite it only having 15 minutes per episode. It has a decent story for a hentai, but it does not spend too much time on it. The art of the scenes and characters is also very good, but I thought the part in the second episode where Miyu has Mitsuru dress up as a girl was kind of weird. Other than that, I enjoyed the other scenes and even with the feminine attire for Mitsuru, that scene was still well animated. Miyu is a good tsundere character and her breast envy does not take up more time than it needs to and doesn't get in the way of the sex scenes.

I think it's a good hentai that's worth a watch unless you really hate incest (even if their not blood related siblings). The story just focuses on Miyu and Mitsuru and their relationship with no side characters doing important. It's just a nice incest hentai about the relationship of two high school students who finally express their true feelings for each other.

This hentai, unlike the others, had a great story development. First, she displays a tsuntsun personality, then after feeling something for her brother, she becomes Deredere. Her character is indeed cute and very innocent, and I too would want that. It was enjoyable and erotic how she is pleasured by her first time with sex. I find this very enjoyable 100/10.

This would have been better without the sex scenes.

It suffered from the typical problem of escalating too fast, would have been far better if the relationship had been teased out more slowly.

I also had issues with how the nipples were drawn.
