I hated this an astonishing amount, especially if you consider the fact that S&M, no matter if it's incest or rape, is my absolute FAVORITE.
But what I can say about this is, it sucks. You definitely shouldn't read it - the 6.4 (currently) review really doesn't lie. The "main character", shall I say, was so effing annoying, I screamed googol+ times. He kept talking about a "red cage" and how he wants to keep doing things for his brother so he doesn't have to dirty his hands. It just seriously disgusts me, his sole existence. And I hate how his brother is the "ringleader" of the group, despite the fact all he can do is provide a masochist's sexual desires to others.
I definitely don't recommend you reading this - it'll be your graveyard if you do. It's a disappointment to the world of yaoi, I don't even know how it managed to even get a 5-star rating. Just fuck no.
