Well as of ep 08 I am wondering if the show has reached the high water mark for it's form of humour as presented in the more tamer version.
08 was totally blah, and without the sensationalism of extreme content, really is just about two non biologically related sisters that want to screw their younger brother and constantly hanging around him waiting for it to happen.
And the brother worship gag is really just a minor support gag of a minor character normally in a series when nothing is really actually happening.
So unless they finally get around to him taking one to bed and actually screwing her ie she gets some non related dna deposited in her, even if they take a pass on showing him actually doing it (that would be actual porn at that point), the show has lost fire.
The return of lets film a girl peeing was also not much of an event (seeing as they have already done this gag more than once), lets come up with new gags eh shall we?
Anime, one of the few things about the internet that doesn't make me hate the internet.
