Absolute degeneracy at its finest. The brother is a true pervert who can only get it up for his sister yet runs around trying to act otherwise hoping the sister doesn't find out.
While the sister who already knows this is basically the same but she is psychotic and would even go as far as trying to cut someone if they try to make a move on her brother. I don't even have to mention she is a stalker to the extreme.

Basically the whole story is the brother chastising himself and trying to act as if he doesn't want to bone his sister while the sister wants him to but she won't make the first move as she takes pleasure in making him fall in to degeneracy.

If you do its your fault
This series is sooooooooo wrong that its actually hilarious again really. A yandere brocon little sister and a tsundere siscon big brother, really a fresh takeon to this so overused ecchi genre. I think the only thing that would give this an even bigger twist would be if the brother was the yandere and the sister the tsun (never seen that before ).

In my opinion a solid comedy manga

at first I thought I might like this, seeing as I don't dislike cute ecchi/romances, and am not particularly against bro-con stories... but forgetting the "done it before and it sold, let's do it again" story, art is what really lost me. The story was iffy enough to begin with, but the hackmeat... deformed... just plain bad art really destroyed my interest. There are three types of art in the manga world: the beautiful, the bearable, and the ugly/grotesque. Kagesaki sensei's work falls deeply into the third.

This series is terrible on so many levels... and I'm loving every minute of it.

The sister is insane, the brother is a pervert that's trying to hard to not give into temptation, it's just so very, very bad... and I want more!

finally, it's actually the Little Sister that's A COMPLETE FRIGGIN PSYCHOPATH. normally it's the brother whose nuts, never gets anywhere, and ends up humiliating himself while she has no friggin clue whats going on.

A yandere brocon sister and her tsundere siscon brother ^^
now that i've read uo to chap 5 this series is getting higher level of awesomeness
and it's even threatening other Otaku culture series

Have you ever read stories about priests being tempted by succubi? Replace priest with older brother and succubus with little sister he can't get rid of and this is what you get. Though you may say that no sane pair of siblings would have those kinds of feelings for one another, you have to realize that the girl isn't sane and the guy is being dragged down by the girl. The girl is pure evil. She's a non-hentai genre version of Tsukasa from Tsukasa Blog. If the brother ever finds out she isn't his sweet little sister, she's the type to knock him over the head with a crowbar, strap him to a bed and break his legs to keep him from running away. All in all, quite a funny read.

Four different groups for 2 chapters. WTF?!

I really don't get why it's taking three months for one chapter. If the mangaka doesn't want to work on it, then don't. Srsly.

Art's pretty good. Finally, the GUY is not the one that keeps trying to get ecchi moments with the girl.

Fair amount of very funny comedy, and the situation makes it so that the comedy is moderately refreshing compared to the other mange protaganists out there with similar genres.

-Thumbs up-

i really like the first chapters.

i don't know why or how the whole sister complex in manga and anime started. but i know:

"ABSOLUT NO SANE PERSON WOULD EVER FALL FOR HIS OWN BLOOD RELATIVE SISTER/BROTHER"

it's just a fantasy from ppl who dont grow up with siblings.

but thats a manga and fiction is ok, i like the theme a lot forbidden love is ever a great drama.

May look like a plain comedy/ecchi (though it still might end up like that) but i think/hope there will be more to this manga with that special sister... working hard towards her selfish desires. Too bad it isnt horror, would have been fun watching her torture some poor female victim who dared to lay an eye on her precious brother.
