I've looked at it long time ago, when there only was about a dozen chapters out and I put it on my wishlist. Came back now when it's fully out and translated to read it. Reviews kinda scared me, but it turned out just fine.

The main appeal of this manga is manipulative mastermind sister, who is set to keep her brother's eyes on herself. All the strategies and mindgames... After couple of volumes of set-up, the story goes into arc-mod, when girls start to get close to her brother for one reason or another. And all of them are weird. It's a fun read, if you are not to sensitive with your anti-fetishes.

The whole incest thing is not explicit enough to turn me away, and at this point I'm almost immune to "fan-service".

Truly a terrible manga, just plainly fails, first and foremost there is almost no actual plot to speak of its mostly just the main heroine trying to get her brother's attention in some "ecchi" way's, later on a couple more females show up and boom, a harem. This manga is also incredibly slow, at least 5 chapters in a row were basically reprints of each other with almost nothing new happening, worst of all its just plain boring, there is 0 appeal for this title. You would be better off finding a different "incest" manga to read. Just goes to show that most title's with long name's (90%) are usually pretty bad

I guess all that people don't read or watch any film with murder, raping, or anything that's illegal or a sin or whatever on it. Judging any story because of that is clearly wrong.

This is a comedy manga first, far from hentai, is even light ecchi (haven't read in a while but I don't remeber any nudity, just underwear). All the characters are messed up, but they are likeable perverts. Try it if you don't stand in a higher moral ground and are looking for some light comedy.

Read a few chapters to see how I'd react to a manga of this nature. Completely sucks. I don't understand why people enjoy incest novels/manga. I guess it's better than committing the act in reality. I just can't imagine why it's so popular in Japan.

Typical brother/sister fetish

This is nothing more than one-step away from a full-on brother-sister hentai story. You have over the top perverted siblings getting themselves caught (willingly and unwillingly) in sexually suggestive situations in a blatant attempt to foster an incestuous relationship. (Sometimes they even admit it to the reader) Throw in a cast of side-characters who jerk the characters around either away from each other or towards each other and this is the end result.

i've read your comments and its highly recommended.. yeah. but uh, i don't know.. i guess its not for everyone huh.. i didn't find it funny at all.. just a young girl wanted to be fuck by her big brother by all means which means do everything she can to make her brother get horny.. that's what comes in to me when i read it.. (even theyre unrelated) so its really weird for my taste..

Read this for it's pure Hilariousness... the girls in this manga are some of the wackiest (and scheming) girls I've ever seen in any manga...

Yes, I'll recommend this because this really isn't incest...

And yes...

The Hilariousness is situational... not a string of cheap one line (and annoying) jokes. smile

Even as much as I like incest and stupid manga, this one just doesn't do it for me. And I have pretty low standards.

Ecchi manga don't usually appeal to me, but I decided to give this one a chance based on its long title alone.

First off, the relationship between the brother and sister is downright STRANGE, not to mention hilarious while I'm at it. I was thrown off by the younger sister's uncalled for actions, which only made me want to read more. My desire to do so was also fueled by how ridiculously perverted and stupid her older brother is.

Yes, he is portrayed as the common Japanese boy with porn in his room, but the guy somehow manages to take it to another level.

If you're offput by the brother-sister part then you shouldn't be cause there isn't much to worry about concerning THAT. Other than that though, if you like funny and weird, then I suggest this to anyone looking for something a bit different and new to read. I'm generally a shoujo and yaoi reader, so whenever I stumble upon a different genre and read something else, then it has to be something that I actually like.

This, I like. (as far as the latest chapters that is)
