After his single father gets remarried, Keita Suminoe not only finds himself with a new mother, but also two beautiful twin step-sisters, Ako and Riko. Their close bond as children soon grows into something more personal, and Keita finds himself in a real bind that he vigorously struggles to escape from.

For the twins, the transition from little girls to teenagers brought about changes in appearance as well as emotional growth. Their love for Keita became something more than brotherly love, as they were both overcome with romantic feelings and pure lust. These innocent girls, being a couple of honest young ladies, could not help but confess their newborn love to their poor little brother. Hilarity ensues as Keita, who refuses to see the two as anything other than his sisters, then starts getting into embarrassing, sensual and lustful situations with them. Will Keita cross the line of incest or will he be able to protect his family jewels?

Kiss x Sis is an ecchi-filled harem anime that may make you blush a bit, but it will also surely make you laugh.


The episodes are numbered 00, 01, 02, 03, etc.

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

Once in awhile I'll come across a great anime that boasts an exemplary plot with dynamic and intriguing characters. Then there are shows like Kiss x Sis, which possess neither of these qualities, but are enjoyable to watch for...other reasons.

I was quite impressed with this show. Sure, the plot is limited to a bunch of extremely sexual scenes and the characters don't have much depth, but Kiss x Sis is able to succeed where other anime like it have not. I've watched plenty of harem/ecchi anime and have really enjoyed some of them. However, I find that a lot of these anime fail to effectively read more

12 episodes....

I made it through 12 episodes of vile, disgusting, uncomfortable, forced smut called a show....

I got through 12 painstakingly bad episodes of one of the worst animes i have ever seen, and for what? a medal to say "I did it!"?....

Was this show worth it?

HELL to the NO!

At best this show is decent. But it's so cringey with forced EROTIC scenes and fanservice of all things. Mix that with lazy animation, bad jokes, practically 2D characters, and a fairly decent but repetitive sound track. And add a sprinkle of disappointment and questionable content mixed in. it's bad.

Very Bad....

This show is to quick to pull 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
