A Deal in Darkness (Dark & Devilish #2) by CJ Holmes
 
I’m damned by my own desires now I've made a deal with the devil
My first mistake was taking Enzo's deal. My second was believing I could escape. The devil doesn't go back on his bargains and this one has trapped me between pleasure and pain.

Enzo is mysterious, handsome, and depraved. He says he wants to turn me into his plaything. He claims he needs me. He acts like he craves me and now he has me in his grasp.

I can’t afford another mistake. I can’t fall for him, but the pleasure of sin is undeniable and some bargains can't be undone. Not when his hell is this tempting and its flames burn this hot.
