Wanna See Her Suck

My lovely and super sexy wife has always loved sucking cock. Ever since the first time she felt a cock get throbbing hard in her mouth and she got so excited when the cum starts filling her dirty mouth. She always swallows unless I tell her to show me the loads or she's taking a nasty facial.
For a long time she's wanting to go to the adult cinema in town and go into a glory hole booth where men can slip their dicks through the hole and into her suck hole.
I like to watch her and even kiss her cheek and feel the dick in her mouth. Love to kiss her and taste the musky flavor of cock on her lips and tongue.
Anyway I have stopped her from doing it only because of the chance of STDs but sure would like to let her show off what a cocksucking slutty pussy she really is.
Anybody else like to watch your wife or gf suck dick?
Anyone try the glory holes at a adult cinema?
