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.

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.

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

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

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.

One of the ecchi greats, must read

After reading up to Chapter 38(the most recent chapter released when this was written) I can safely say that KissXSis is my favorite ecchi manga of all time. Why is it so good? For starters, the main character, Keita, isn't searching for an unobtainable girl that eventually falls for him. His twin, non blood-related step sisters, Ako and Riko, are the ones in love with him, and they openly show it(even infront of the parents, which fully approve and support it).

The two sisters are what make the manga so popular. They each want to get Keita, they each kiss him ALOT and because of that there's plenty of conflict between the two. The funny part is how each sister tries to isolate Keita and herself, and what they have planned.

There are alot of chapters that push the ecchi to the max, where one more step and it would be considered Hentai. Look at it this way: By chapter 10, Keita has gotten dragged into situations by either Riko or Ako that exceed everything that other ecchi manga like to-LOVE-ru and Love Hina did in all their chapters.

Another thing that should be noted is that this manga loves to poke fun at relationship situations looked down upon by society, such as Student-Teacher relationships.

At this point
Spoiler (highlight to view)
By chapter 8 or so(don't remember which exactly) Keita has a flashback of when he was young and how he wanted to marry both his sisters. His father replies by saying that it's illegal, which saddens the young Keita. In later chapters, he openly admits that he loves them both, which makes it clear that Keita will have to make a decision one day: Who will he choose? The sweet, closet-pervert Ako? Or the tough, honest Riko?

It's because of the decision, and how they both are given the same amount of focus, that I really hope it doesn't have a Harem/improper ending. to-LOVE-ru, a series I fell in love with, had the same problem with the ending. Keita needs to choose one of his two sisters, and we, the readers, should get a foreshadowing when the manga nears its end, about who Keita will choose. His sisters love him too much, and he loves them too much, for Keita to not pick any.

In short, excellent read, every chapter forces you to read the next!
