I've written before about my wife fucking a young coworker of hers way back when we first began dating.
After a few months, she wound up moving into my apartment, and as it was a fair distance from where she was living, it brought an end to their fling.
Somewhere around 2/3/4 years later, we bought our house, coincidentally in the same town where she lived before, but in another area several miles away.
We had been living here for several months, and it happened that I had an opportunity to leave work early on a Saturday afternoon, and damn sure took advantage of it!
As I was getting closer to the house, I noticed a pickup in the driveway and didn't recognize it as anybody we knew. It didn't set off alarm bells or anything; I was thinking it could've been one of her friends, maybe a family member... who knows? Shouldn't be a big deal.
I came through the front door and looked into the living area....nobody. Peeked in the kitchen, nobody there either.
So I'm headed to the stairs to go up and look there, and no more make it to the staircase when this young guy popped out of one of the bedrooms.
Yes, that same young coworker she used to fuck. And, apparently, was at least one more time.
Although I didn't actually 'see' anything, it was clear and obvious they had not expected my arrival, and were quite surprised... and panicked. Trying to get dressed and get downstairs before I came in, but didn't quite make it.
