When Keita Suminoe's father remarried, not only did he gain a new mother, but elder twin sisters as well. Distinct yet similar, the homely and mature Ako is a former student council president, while the athletic and aloof Riko is the previous disciplinary president. The three of them have been together since kindergarten, resulting in a deep bond between the siblings. However, over time, their relationship developed into something more romantic—and erotic .

Now in his last year of middle school, Keita has already received a sports recommendation, but it's from a different high school than his two sisters. Disappointed, both sisters try to change his mind, and he agrees, giving in to their desperate pleas. Unaware of the consequences, he now has to attempt to study for his high school exams while warding off the advances of his lust-driven sisters. With their parent's blessings, Ako and Riko strive to be Keita's future wife, leaving him to try his best to keep the relationship between them strictly platonic. However, with two beautiful girls vying for his attention, will Keita be able to withstand the endless temptations?

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

Probably the most honest, straightforward and amazing ecchi out there.
I wouldn't say is borderline hentai, but it will seem so on moments.

I love pretty much all of it. The story is not mind blowing, but its very well explained.

There's way more than just accidental boob touching. Way more.
Your mind will scream omg.

The thing I admire and love about the story and the execution is how everyone but Keita sees the stepsister thing as completely normal. That's where the fun is. He is barely able to hold it and is constantly under some guilt trip. Not to say his sisters aren't, but less so. Even his read more

First off I'm a big fan of the "Hoshizora Monogatari" credit music (I seriously love that track). The Characters weren't that whiney either, had good voice acting, and would give their sounds a 7.

Many people like to rate Ecchi pretty low because it's Ecchi, but I'd like to not be 'that guy' and will categorize this as being an Ecchi, and not Death Note or Fate/Zero.

Kiss X Sis in particular is a unique Ecchi. No other Ecchi has made me feel this way thus far, and has done a great job at captivating mood in multiple situations both eroticaly, and in humorous other read more
