Vacation threesome [MFM]

This is my first time posting here and hopefully it fits. It is still a found memory of mine lol

My ex and I had a very open and honest relationship when it came our sexual desires. There was no topic that was off limits, we provided each other a safe place to share without judgment, and we both mutually agreed on what desires to explore. Over the years we explored a lot of desires lol

About two years into our relationship she expressed an interest in being with two or three men at once. After a lot of conversation, some roleplay, we decided our upcoming summer vacation seemed like a perfect opportunity. So around a month before our trip we replied to a few posts online from guys in the area and she narrowed down the field. We found a guy she was really attracted to, was available the night we wanted, and he agreed to get tested beforehand which turned out to be a good thing later on. Then over the next couple of weeks she was regularly sexting him, just fueling both of their desires. It was cute how excited she was.
