How a fantasy turned into reality

Hey guys!

It's during last year christmas and I met a guy on reddit with similar cuck feelings who's married and decided to meet for a coffee. We showed each others partners pic and decided to fap together. He was in his late 30s. Then both of us decided to hang out together on new year eve along with our partners(our partners didnt knew about our fantasies)and met on one of the pubs.

He really Started liking my gf and started hitting on her which eventually i can see. But her wife was bit conservative and didn't talked much. We had a good outing and left for the day.

Long story short- he started texting with my gf and informed me the same. After a month he met her in a cafe and did informed me the same. Later those normal conversations turned to sext and eventually they started to seeing each other. He took her for a nice resort for the weekend. He used to update me everything and my gf unknown of our intention hided this with me. He enjoyed alot and he used to explain me what are all they did and used to fap with me when we met.
