Keita Suminoe has two older (not blood-related) twin step-sisters who love him in a lustful way and have no problems expressing it. They even like to compete about it; much to the laughter of his friends (which he usually endures without problems). One day they come to his school to give him his lunch, resulting in him getting angry due to the atmosphere. To counteract his anger, they confess their tender feelings for him in front of everyone and leave. Feeling sorry he chases after them and says that he'll study hard in order to get in the same high school as them.

Drastic change in pace, there is a clear main herione

For the first 60 chapters the author gave each girl equal attention, but after that its clear who our MC gets with, this herione received so much attention that she absolutely outshines every rival. The author wrote himself into a corner now.

Funny, sweet, and sexy

I dunno why everyone wants this guy to have sex so damn bad. I honestly never even really thought about it. Too busy laughing my ass off and keeping my boner from shooting off like a rocket. It's funny. After re-reading it a few times, I feel like the first few volumes are the least interesting. But then it gets really good. One of the best harems out there if you just wanna laugh and feel good. Good romance too. I know some people don't like Sensei, but she adds a sweet romance aspect to the manga.

Ok, I don't blame this for being simplistic or borderline-h. I really don't. I do blame this for heroine-swapping 60 chapters into the story.

Simple is OK. Nonsensical is not. What a joke.

Seriously, what's hentai w/o sex? it's like say "porn w/o sex" How in the hell you can make porn w/o sex? same applies here, this is ecchi not hentai, or if you want to say it in occidental terms "erotic" so no need for sex scenes in any point and looks like some people is dissapointing due the lack of sex, well, welcome to ecchi.

Hentai-without-sex is point on

Rating: 1.0 / 10.0
This series a joke as it manages to fail on every level as both a storytelling device and as a romantic comedy. It also fails to give you the good hardcore porn will give you because it lacks "real" sex. Just fetish trash and highly creepy teasing but what else should I expect from a man who started his "career" with piss swapping lolis and futanari rape? Stick to Koi Kaze (8/10) if you want to read about incest and read the reviewed Ike! Inachuu Takkyuubu (7,5/10) if you want to read an amoral sex comedy.

The male protagonist and his 2 lustful sisters are almost into hentai land. Take any hentai manga, cut off the porn port, stretch out the introductory part, slap the happy ending at the end, then you have a typical KissxSis chapter.

It is original in its own way compared to other harem series though >.>

edit: like the comment below me said, its basically soft-core porn, esp. the later chatpers. Have to edit my rating because of that :\

twincest is wincest am i right guy. but seriously idk if it count if they not blood-related. overall it an ok series that pander a little to the siscon, lolicon, teachcon, along with other fetishes. every chapter feels like sex is gonna happen but it dont, which make me a sad panda. now the character are pretty decent with a the teacher being the best.
A good read if you into harem, hentai without the sex, or forbidden love

Good Ecchi

Rating: 6.0 / 10.0
If you're looking for ecchi goodness and you don't particularly care about step-incest, this is the manga for you. compared to other harems, the girls in this one are refreshingly open about their feelings. The protagonists also gradually warms up but if you ask me, it was more entertaining in the beginning when he resisted more. Good ecchi.

why not harem, why only one?

this is mostly a response to dufus397

Spoiler (highlight to view)
why should he be paired with only one. to love ru got canned and had a true harem end. but she also made a damn good point, he would be the ruler of the universe and to hell with earths laws, you rule the universe, you make the law, lets all be together. now this whole manga is based on a "taboo" if you call step siblings a taboo, so why not break some more. i mean in the bit i have read of it, the two sisters seam to be a hell of alot close than sisters should be, and almost all the conflict starts with them not wanting him to be with he other instead of her. in all honest i think that him deciding that that law is retarded would be the best ending for this manga. again im not to far into it so i may be wrong.
