Shamefully Broken by Loki Renard

Since the arrogant, infuriatingly sexy brute spanked her like a little girl on her eighteenth birthday seven years ago, Ellie has done her best to avoid Mason Malone, and he is the absolute last person she wants to come crawling to asking for a favor. But with her brother deep in debt to the wrong people and her life in danger, Ellie knows Mason is the only one who can help her.

Mason agrees to intervene, but the rough, battle-hardened former Marine turned millionaire owner of a private security agency is no knight in shining armor, and his assistance will come at a high price. In return for his protection, Ellie will be made to surrender her body to him utterly and completely, to be used anywhere, anytime, and in any way he pleases.

He will not be patient with her. He will not be gentle with her. He is going make her pay for all the years she spent looking down her nose, pretending she was too good for a guy like him. She will moan, plead, and cry out with pain, humiliation, and helpless, desperate need as he strips her bare, punishes her harshly, and then takes her over and over, each time harder than the last.

He is going to break her in the most shameful way imaginable, and she is going to beg him for it.
