Torn: A Billionaire Romance

No names, no strings, no inhibitions. That was the deal I couldn't keep. Being a billionaire wasn't easy. I'd just ended my relationship with my ex. A supermodel. Our relationship had lasted fifteen years. And still might have been had it not been for my ex-best friend, Who'd been sleeping with her for the last five years. So, no commitments for now. But everything changed when I saw her. She was stunningly beautiful.
She had dark skin. A body that was slender and yet curvy in all the right places. I made a move on her and made her laugh.  We hit it off and agreed on spending a week of wild lovemaking. After the week was up, we parted ways. Six months later, we meet again, but this time, instead of being her naughty billionaire.  I'm going to be her grumpy boss because she is going to be working for me.
