jpsauce has given good advice, about the massage.
Once, I bought a professional massage for my wife, from a young, well-built black man. When she asked what she should wear, he said "as little as you feel comfortable with. Nothing, if you want to", so she did undress, COMPLETELY in front of this other man.
He was very professional and did not register a reaction in any way, but she lay on his table completely *******, with her tits and pussy right there for him to look at as much as he wanted to.
He massaged nearly every part of her body, including her ass and tits, only coming right up to her pussy without actually touching it. And all the while I was right there watching this "other man" put his hands all over my wife's naked body.
After he left, we fucked like crazy, and though neither of us would admit it, we were really turned-on by the fact that HE had seen her naked and handled her body too.
My only regret is that I was not brave enough to ask her if she would let him fuck her, as I am sure he would have done so.
