Looks like the artist hasn't read the source material (or maybe they just wanted an excuse to draw NTR).

@xTtotal I'm not caught up, but the blue haired girl loves her older brother who is sitting in the back there. The guy who is doing her in this picture hypnotizes her into killing her dad the king and then marries her in an attempt to get the throne I think but the twist is she was never hypnotized from the beginning and the guy who is banging her in this picture was being used by pretty much everyone. I'm only a little past the anime, but i'd guess @Garbouw Deark is implying that the guy screwing her never had a chance. Since he's a chump.

If the blue haired girl wasn't brainwashed and killed her dad to play double agent, then this could be part of a long-con on her part.
I could easily see her falling into her brothers' arms and begging him to help her erase the memories of all this by having sex with her - I've seen it in a few story driven h-manga.
