Ok this is actually an old one that I wanted to do more with but never got around to it.
I'll more then likely redo this again as the second half of it.
I always liked The Robin Character and can't figure out why she would ever be drawn being forced into sex. Seriously I see way to many Doujinshi hentai with her in it where she's totally being abused. Not a fan of those types.
I mean seriously She's got multiple arms, if anything she's going to be raping the guy.
So like I said I'll get back to this idea again later, but just thought I'd post this.
