Found: MM Romance BDSM with damaged character that has two little brothers

This book is about a BDSM club, owned by two brothers (I think) that also have a fight ring to let off steam. The two brothers noticed that one fighter, in particular, was very good despite his small stature and always went after the big guys, they decide to find out more about him and his past. Turns out his parents died in a house fire and his two little brothers lived with his aunt, he would occasionally visit them and it turns out that he fights not only for money but to punish himself for not saving his parents. The two brothers end up taking him in and showing him he doesn't have to resort to that to feel something. I didn't finish this because it was too intense to read, but I thought of it and now I HAVE to know the title or I will never be able to rest. I remember that the fight club is at the two brothers' house, where they take the one fighter to train him, I guess, as a sub. They have like a cage fight that they let their BDSM members participate in to let off extra steam and anger.

Please help me out.
