I was on a lad’s weekend away with some friends. One night one of the guys randomly showed me a photo on his phone of a naked woman. You couldn’t see the woman’s face.
I said, “nice. Who’s that?”
He said it was his wife.
I’d always had a thing for his wife so I said, “wow, even nicer.”
Later that night I was in bed in the hotel, plucking up the courage to send him some nude pics of my wife. I finally did it, choosing a few that showed her face. I can’t remember what I wrote, something about enjoying seeing his wife and maybe we could trade a bit. He replied the following morning, thanking me for the pics of my wife, but also saying he couldn’t remember showing me his wife, and that he can’t have done because he didn’t have any photos of her on his phone. That should have been my first clue.
A few weeks later he messaged me about something late at night. We had a brief conversation before I mentioned that he hadn’t shown me more pics of his wife yet. He said sure and promptly sent me a photo of a naked woman, again not showing her face. I replied with a photo of my wife, obviously. We traded around ten to fifteen photos. None of his showed a woman’s face. All of mine showed my wife’s face. This guy and my wife are friends by the way.
I was obviously suspicious and showed the screenshots from the WhatsApp thread to a guy I was chatting to on kik. He said all of my mate’s pics were lifted from a voyeur cam type site. I can’t remember what it was called.
I called my mate out on this and he denied it. I haven’t seen or spoken to him since. I’d still kinda like to see him again because he hasn’t seen my wife in person since seeing her nude pics, so it would be interesting if we all met up. That said I obviously feel incredibly betrayed and fucking stupid/embarrassed etc.
