41 [M4A] I set my gf up with a very skilled pleaser

This is a story about an ex-girlfriend who I still think about a lot. That's just for context.

This X and I had a very lustful and satisfying sex life. We didn't live together, and I'm a part-time parent and we both found ourselves very lustful for each other every time we would get together. I thought for the longest time that I was likely more sexually experienced than she was just based on her demeanor and what she was interested in. During some pillow talk one day we stumbled upon the topic of wild past, and I was delighted to find out how arousing I found it to hear her hint that some of the things that she had done in her twenties.

With a lot of caution, we explored my enjoyment of her history, and her enjoyment of glorifying past sluttiness. I've always enjoyed her pleasure very much. Whether it was me giving her orgasms, her giving herself orgasms, but now hearing about other people being involved in her pleasure was very exciting.

One day I found the random acts of muff dive forum here on Reddit and a beautiful idea was born. What if I found some skilled stranger to please my sweet girlfriend for as long as she wanted. I was admittedly surprised that she was into the idea...
