I don't know any of this manga because they are not translated but I do wish to read one which is translated. So can anyone tell me what manga is this...

and

No idea. even saucenao can't find a match.

It's part of a NSFW series called PixelitA which can be found at Danbooru.

I wonder if it has a anime adaptation?
