I knew my wife was "cheating" on me a few times.I say "cheating"because I always let he know that if she ever got the itch, to scratch it. I would have preferred her let me know and use it to spice things up, but she couldn't. She tried once, calling me on the phone while I was away, she let me know she was at an ex boyfriends watching porn, and i could hear the occasional suck sound. But she of course, would deny it. A very scorned wife sent me a short video from her husbands phone of my wife sucking his cock.She did an amazing job! I was not angry at all...the other wife, was looking for ammo. In the end, my wife never confessed to anything, but I know she swallowed more cocks while I was away, but I think she actually feels a bit guilty lol! Good luck!
