Not my story but I enjoyed witnessing this and still think about this 30+ years later. Although the girl didn't directly cuck the guy to his face, everyone knew what happened and in my books that counts.
In my friend group there was a couple who had been dating for almost a year. Prom was coming up and my buddy (Dave) was excited about taking his gf (Stacey). They had messed around but she was still a virgin.
She dated another guy in our group (Paul) a couple years before and he was the first guy she'd done anything beyond kissing. We all knew that she still had a thing for him. He graduated high school early and had left for college, but was back for the summer before our year ended.
Stacey was inexperienced but she wasn't shy. She'd ask a guy out and not wait to be asked. So it wasn't a surprise when she asked him to go to prom. What was a surprise was that she asked Paul. She said it was because they had been friends for years, long before David (which was true) and that this was one last chance for friends to go out to a formal event. Outwardly Dave seemed okay but we all knew where this was going.
It turns out Stacey booked a motel room for the night of prom because she wanted Paul to be her first. After prom a bunch of kids went to this motel (it was known as a place to rent a few rooms and have a party away from parents -- everyone just said they were staying at another friend's house).
Stacey and Paul were there and then they were gone. We went over to their room and knocked on the door. No answer. I pressed my ear against the door and could hear the unmistakable sounds of a girl being pleasured. I swear I heard her say.
"Oh god it's so big!" followed by a moan, a long pause, and a long gasp of relief. We moved over to the window and could see through some spaces in the curtains. Not a lot but at one point a couple of us got a really nice view of her bouncing in his cock.
Yes his dick was big (something we all knew from the showers after gym class) but so were her tits. And at that age they were the perfect balance of firm but bouncy. It was all I could do to not beat off right there.
The following Monday we are all back at school and Stacey and Dave are acting like nothing happened. But we all knew and I'm sure he did too. The following weekend Dave and Stacey returned to the same motel (turns out it was the same room; not sure if that was on purpose or just coincidence). This is where Stacey lost her virginity to Dave. Seriously. That was the story they both told their friends and we just acted like it was true.
They dated most of the way through college but it was long distance. Dave never strayed but Stacey was regularly bedding guys at her school. Near the end of college Stacey met a guy in med school who she said was the best fuck of her life.
She dropped Dave like a hot potato and ended up marrying this guy. I see her on Facebook and they are still married but from the "girls weekend" pictures she posts, I am certain she is still getting fucked all across the world.
That's what started my cuckold fetish that I am trying to get my wife into.
FUCK MY WIFE!
