Unbridled passion

I'm a rake.
A playboy. A womaniser.
I sleep with everyone I meet, and I'm not ashamed to admit it.
When my best mate opens an erotic establishment, Club Sin, and asks me to work there as his site manager, how can I say no?
Right now, we're on a business trip across the United States, visiting other perverted clubs. I couldn't be happier. Life is good.
But then, out of the blue, Hunter asks me to sleep with his wife. While he watches.
I'd do anything for my best mate, but I should flat-out refuse this request. Isabel is the woman of my dreams, but she belongs to him.
The very reason I should say no is also the reason I say yes.
Because the truth is, it's not just Isabel I want.
Isabel and Hunter are the two most important people in my life, and if we go down this road, will I ever be able to stop?
I don't know if my best mate understands just how much I'm willing to do for him – and why.
