[Akito Kinomoto]

I'm not sure why there's a poll in a recommendation topic, but I'd rather just ignore that and second Ore no Imouto. KissXSis would probably be up your ally too, and maybe Onii-chan no Koto.

For ecchi things in general that aren't incest, there's Shuffle! and Chobits, both of which have an English dub.
