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.

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

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

My own morbid curiosity made me watch this and I hate it to an extent. Kiss x Sis is a romantic comedy (if you can even call it that) anime where the main character's (step? sorta...) twin sisters try to have sex with him. Half way though the anime there is an obstacle where the main character has to pass a test of some sort (I forgot most of the anime sorry). Due to this the sisters try to help him pass while still trying to get dirty. Also the pups in a luck charm is fantastic... The only redeeming factor, however, is the ending read more

It tries to be a passable Ecchi Anime with a vague story to propel these absurd scenes and reasoning, but for the love of christ it is constantly pushing the incredibly weird fetish thing so far into your face that it just becomes literally un-watchable.

We get that they are non-blood related siblings and it's relatively acceptable. Their parents allow it and downright endorse it along with their neighbours.

The main character is a socially and sexually maladjusted dimwit, like most Harem Leads, except in this case he seems to have incredibly strange fetishes and having roughly every single negative trope possible. All this while simultaneously denying 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.

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: Ore no Imouto ga Konnani Kawaii Wake ga Nai.
Both anime have the brother and sister relationship.

The difference between these two is that kiss x sis is more on ecchi and doing stuff with your sister while oreimo 2 is more on hanging out with your sister playing eroge games.
