Looking for more obscure ecchi loli anime

[booboolokaa]

I am not looking for the usual names like kodomo no jikan and fate kaleid liner prisms illya. While those are great I am looking for the more obscure or the ones normal sites refuse to list for whatever reason.

I've seen a few of the more slice of life types anime I just mentioned but I am now looking for some more maybe darker ones as well.

Although I would also like some more young - old relationship anime if they are at least spicy.

So please name the more unknown ones that are not on the usual lists. The more ecchi the better.
