Fanservice/ecchi anime or manga like KissxSis?

[_ETERNAL]

I'll be blunt: KissXSis is the single best fanservice show I've seen, period. I'm not sure exactly why, but in terms of pure...allure...it draws me in more than anything else of its kind. So, are there any other ecchi anime or manga similar to it that you might recommend? The story can be different, of course, but I want something similar in tone, not just a generic name-the-harem recommendation thread. I also don't mind if it crosses the line between borderline H and normal H, as long as there's nothing non-consensual in it.

I'm not sure what you liked about Kiss x Sis exactly but:

Yomeiro Choice is similar and similarly incestuous, perverted, borderline, etc. Or so I heard.

Kanojo wa Kannou Shousetsuka is my new favorite. Nice ecchi and, rare among the genre, has a plot that doesn't feel retarded.

Yuria 100 Shiki is both gut-busting hilarious and sexy.

I'll leave the list-the-harem to somebody else.

The greatest fanservice anime I've ever seen is Kanokon. It takes the exxhi to the furthest possibly level without revealing everything, the plot is interesting, and it has one of the best endings in anime history.

And if you like yuri, the currently airing kanamemo is amazing.

Try watching TonaGura! (http://www.animenewsnetwork.com/encyclopedia/anime.php?id=6676), I guess it's fits the theme altough it's only normal H and not borderline. The story is also quite good...

hmm i would recommend kanokon and nagasarete airantou

This isn't really like Kiss x Sis, but since it shares the same bro x sis theme, I'd suggest it nonetheless:
Boku wa Imouto ni Koi wo Suru (http://anidb.net/perl-bin/animedb.pl?show=anime&aid=3318)
.. BUT it's very different in terms of feel with a more serious treatment involving real twincest

it's only 50 mins and I guess it's meant to serve as an intro into the manga though
There's also a Live action version
