Nude massage for wife

My wife had similar experience, she called a masseur home after having multiple drinks at dinner. Kept all her dinner clothes on for the massage just in case she changed her mind, so the guy started with a normal massage and slowly hiked her skirt up and worked his fingers to her crotch. The guy was a pro, she was never really into fingering with me but was moaning intensely and grinding her crotch against his hand
So hot ! A fantasy of mine. We live in China and (straight) massage is a big thing over here - everyone goes and loves it. However there are places (esp for men) that will give a happy ending or more. And there are now more than a few places that do the same for ladies.

I often fantasise that my wife goes to these places and gets touched, rubbed off, stripped and/or fucked. The last highly unlikely but I'd love it if she was getting an orgasm somehow ! And I'd love to know !
