Oh, I just feel the need to give the details of the evidence of her cheating now (because I’m so turned on just thinking about it).
My wife went out to a party. I really can’t recall why I didn’t go. But I didn’t and instead stayed home. She was dressed up and looking fantastic. Later in the evening, I got a text from a friend who was at the party to say that my wife was obviously having a really good time and attached a photo of her kissing another friend if mine. These two had been quite flirtatious with each other fir a while. I had no problem with the image, to be honest, but it did look like a proper passionate kiss.
I was in bed when she came home in the early hours of the morning. I woke at the sound of her coming in, even though she was obviously trying to be quiet. She was in the downstairs bathroom for absolutely ages before coming upstairs. This made me a bit suspicious, so I acted like I was asleep and watched in the darkness as she got into bed. I was a little surprised to see that when she took off her top she was no longer wearing a bra. She was definitely wearing one when she went out. Next she took off her trousers and then her panties too. This is unusual because she always sleeps in her panties.
Next morning, she told me she had to go to town urgently and disappeared in her own pretty quickly. I was most suspicious by this point (and getting quite turned on too), so I went to the laundry basket in the bedroom and found her panties from the night before. They were black silky ones and in the gusset was a large amount of what was obviously dried semen. I’ve never looked in her underwear like this before, so to make sure I rummaged through the basket and found all the other pairs. None had any such marks in them. But this wasn’t a mark, it was a large amount of cum.
I realised that not only had she fucked this guy, but she had let him cum inside her. I had a vasectomy years beforehand, so she was not on any birth control. The dash to town made sense, she needed a morning after pill.
A few days later, my friend came to the house for something I had arranged with him long before. My wife seemed keen to answer the door to him. There was a very obvious awkwardness between them, but not anything unpleasant. We are all stiill friends but I don’t think either of them know that I know that they fucked. I’ve even worked out where it most likely happened.
It turns me on still to think about it and even more so now that I’ve written it down. I’m glad I never confronted them with what I know. It has retained the cheating aspect of it, which is what still turns me on.
