For the most part, this is a really well done erotic story. I do want to be upfront to anyone interested in this manga that it does include fetishes, mainly peeing, and it does have a thing about non-consented actions. There's even a whole chapter on a non-consented action happening to one of the characters. If that sounds like it's too much, this isn't for you. That's okay. At least you know. Now, for a series that's mainly about sex, I love that nearly every sex scene is different. The author really expresses the body in different positions in a very energetic manner. I love the main characters: Oono,her sister, and Tsuda. They're adorable together and the first few chapters of them getting it on are some of the best. I love all their dynamics and even some of the side characters give interesting flavors to certain chapters.

I will say that the series did go too far three times for me and all three times it was out of left field; it either didn't need to be in it or it went against what the character would have done.

That said, I did enjoy the ending. Pretty typical, but it milked it. The choreography was well done and most of the new characters and events that happened I enjoyed too. It's just that this won't be for everyone.
