This happened 6 months after we started dating. She had a volatile relationship with her ex but they had great sexual chemistry. One day she tells me her ex in is town and that he wants to apologies for something and return some stuff. I Basically handwave it thinking not much of it...

So after 2 years into our relationships we started to explore cuckolding and once she hear i have a huge cheating kink she finally confessed. That day she met her ex at the park, it all started innocent, he really did apologize, he really did return some stuff and also bough her a drink. They started talking and obviously talk went to memories of sex which made her nostalgic and horny.

They ended up fucking in a public park, her sitting on his lap with a skirt and bouncing on it. They fucked while people walked by in broad daylights, hidden but still in sight if one were to look. She said it was one of the most thrilling experiences.

She jerked him off to completion ans got some of his cum on that skirt. Funny thing is I was doing laundry that day.
