My 38(M) wife 38(F) of fifteen years is cheating on me. She got a new smart watch and couldn’t get it to pair up. She handed me her phone. As I was working on it, a photo was sent to her messenger from one of her male coworkers. She’d talked about him before. He was one of her older brother’s friends. I felt like snooping a bit so I opened the message. It was the thickest cock I have ever seen with the message “I can’t wait to stretch that MILF pussy.” I looked back through the messages. She had sent him nudes, masturbation videos. They had been at this for months. I took screenshots and sent them to my phone. My plan was to confront her….but the more I read through their messages, saw what a slut my wife was being for this man, the more turned on I became. I’ve cum to their messages three times today. I haven’t confronted her and probably won’t. It’s such a turn on seeing this side of her even if she thinks I don’t know.
