If you could watch your wife do anything, What would it be?

Had a lady try to negotiate a discount on a hot tub repair many years ago. I let her lure me into the hot tub I just “repaired” ( user error that I wasn’t going to charge her for anyway)
Four hours later and a half dozen loads of cum in an on her I finally left for the evening.
She became a regular client for years.
Happens quite often. My wife's BFF upgraded her fireplace offering her body to the installer. My wife has never admitted paying for stuff with her mouth or pussy, but I would not be surprised, and actually thrilled to have her tell me the details.
