Keita has two older step-sisters, Ako and Riko, but since they aren't related by blood, they love him in a lustful way. After a mishap at school, Ako and Riko finally confess their love to him. Keita dislikes the thought of seeing them other than brother and sister, but as he tries to enter the same school as his sisters, he slowly becomes attracted to them.

As far as I’m concerned, the best (and probably most honest) ecchi show next to "B Gata H Kei".

[Quick Review (Weighting, Scores)]

Story (*1.5): 5 – neutral score, as this has no story – which works in favor of its purpose.

Characters (*1.5): 7 – no development of any sort but fun characters and bearable male lead. Consider them as means to an end.

Art (*1.0): 8 – very polished, cute character designs (not too childish), normal-sized breasts (TYVM).

Sound (*0.5): 5 – average. If you like cutesy J-Pop you may enjoy it more than I did.

Enjoyment (*2.0): 9 – extremely sexy with certain comedy value. Look no read more

I can't do it, I simply can't do it. I can't even make through one episode. This is the most putrid, vile, fucking piece of filth that Japan has ever spawned from the depths of hell itself. There is no way, not one word that can describe how fucking ridiculous this "anime" is, This is literally the most disgusting piece of animation I've ever watched, disgusting, not the worst, but that's like saying a bag of garbage with shit in it doesn't stink as bad as the open air pile of shit next to it, because it's nothing but shit in the long run.

This is how you do pure ecchi correctly. No attempt at an excuse story which no one cares about anyway, no mindless tits and panty shots where it doesn't make sense, no generic harem elements. Just straight-up lewdness of the very highest degree, and the closest thing to hentai you'll ever find without actually crossing the line.

Kiss x Sis can be described in pretty much a single sentence: a guy named Keita and his two step sisters Ako and Riko doing horny and perverted things to each other around the clock, solely because they want to. That's all. That's all it needs to be. What read more

Unfortunately I watched this series after the adaptation 2010 version, but it mattered little. The little prequel story episodes ended from OVA episode 0-around 6-9.

Around those episodes is where Keita is already accepted into Tamahide highschool and funny episodes revolve around events that happen afterwards. The OVA episodes are no different from the 2010 adaptation, however the few OVA episodes that were set before Keita entered Tamahide, I'll have to say, a lot more ecchi and borderline hentai I have seen, that it rivals To Love Ru Darkness.

Nonetheless it doesn't matter too much the order you watch the two anime, they both read more

Anime: Yosuga no Sora: In Solitude, Where We Are Least Alone.
Yosuga no Sora has pretty much same theme, except the arcs in Yosuga no Sora.

both of them includes sister-love. but yosuga no sora is a bit more...explicit.

One of the few animes in the Mature Ecchi Incest genre.

Anime: Haiyore! Nyaruko-san
Girls/Girl trying to seduce guy...

Haiyore! Nyarko-san is less perverted than kiss x sis,
Kiss x sis has the incest thing while Nyarko has sudden girl show up thing.
Nyarko has Action as extra genre.

Though if you're into like "all girls like one guy and try win him" thing (and a bunch of ecchi scenes) you'll like this one :P

Anime: Oniichan dakedo Ai Sae Areba Kankeinai yo ne!
Comedy and fanservice based around brother-sister incest.
OniAi takes a more harem-oriented approach while KissxSis focuses much more on the sisters.
Both are based on the premise of the sister(s) lusting after the brother, with the brother resisting with varied success.

Anime: Asa Made Jugyou Chu!
Both feature a teacher falling for a male student they feel they must take responsibility for, plus other classmates thrown into the mix (esp. in the manga)
