There are four stories in this manga and they're all independent, meaning one-shots. Three of which are short incest yuri's and the last one is a longer love non-incest yuri.
Overall I liked them all. The first one is of a sister going to get married and has a sexual tete-a-tete with her younger sister. Well stuff happens and the younger sister gets her sexual comeuppance. The story was entertaining but definitely not romantic or in anyway realistic. It was a quirky beyond ecchi piece more along the lines of straight hentai in my book.
one was definitely my favorite. Two sisters stuck at home to make the evening "meal". The older sister definitely makes a meal of her sister much earlier. Lots of crazy stuff going on here along the lines of extreme naughtiness and hentai love. But despite all that I really liked it. No romance, but the girls are crazy. It just shows you what happens when cats get into the cooking wine while having a hard time understanding kanji. It was this story that pushed my enjoyment to a six.
The second story is about a model who needs big boobies for a photoshoot and learns a special massage technique from twin sisters. I liked it for the utter absurdity of the situation. It reminds me of the first story in a lot of ways. All in all all the sisters in each of these stories are crazed. It's not my favorite but definitely enjoyable.
The last story is a love story gender-bender of sorts but the yuri version. ^_^ It actually is a deep story because although it doesn't deal with it a great deal it provides a realistic societal double-standard. Why is it, that heterosexuals can display they're feelings without fear or rejection by society or fear of what the other individual may say or do....Yet in the case of homosexuals they are faced with the burden of loving someone who may be heterosexual and could get rejected upon approach. On that level it was a deep story and definitely hits the silliness of the other three stories in the solar plexus. I enjoyed it very much. It has lite smut and more ecchi lines I find than the others which were straight hentai.
I think that it's definitely fun to read. If you're anti-yuri and girl love or anti-incest pairing then this is definitely not for you. If you don't care and just like art or can easily ignore sibling love and see them as just two girls acting out sexually then I think you might have fun.
Overall good fun for the hentai people since there were many silly, funny sexual moments abound. Might be a bit extreme for others, except the last story. As for the art, I found it very well drawn. Leaves nothing to the imagination. ^_^ Nice work. In each of the stories the characters are a bit superficial since the sexual acts were more prominent except in the last story. They tried to give the last story depth, I don't feel they were successful overall with the characters or stories but it was definitely deeper than the first three.
Note: By the way the girls on the cover are red herrings.
