Co worker fucked my wife (50) after a night out

Went with my wife and a co worker who she’d never met to a local bar for drinks. I got called back to work for an emergency. They stayed there drinking, he later sent me a pic of my wife at the bar looking a bit drunk and asked if I would mind if he tried it on with her. I jokingly said I wouldn’t mind, then an hour or so later he sends me another pic of him fucking her!
