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 ...

This is undoubtedly one of the most heavy ecchi series out there, and that results in quite a few scenes that are both daring and memorable. However, the show also resorts to cliche ecchi harem situations more often than I'd like. It's still pretty funny, though. The premise - the male lead who has two step sisters lusting after him, with everyone but him thinking of it as completely normal - was actually one of the main sources of comedy for me.

Characterisation is on the simple side, but Keita's sisters and teacher are fun characters nonetheless, each bringing in their own shade of ...

I regret being born because I had to lay my eyes on this utter trash. The technical aspects are fine, but the characters are disgusting, the plot is disgusting, the idea is disgusting, and my life is just that much worse from watching this. I nearly threw up multiple times watching this, and I'd like to think I'm pretty hard to disgust. I watched this ~5 months ago and I still have flashbacks when people mention anything that could remotely remind me of this. I honestly would have rather fought in world war one and get actual war flashbacks than have seen this. Unless you ...
