Most of J's affairs have been with co-workers, and the opportunity to enjoy them during business trips has been a LOT of fun for her/us. Most of those trips are 3-7 days long, which allows for a LOT of unbridled intimacy to tkae place. When she is traveling with a Lover, there may be days when I don't hear from her which only adds to the Cuck Angst we all suffer from!!
It also allows for a higher level of intimacy to take place too, which adds to the excitement of the lifestyle. She can spend DAYS with her Lovers, versus a few hours in the evening, learning what they like and want, them learning what she likes and wants, it allows them to experiment with things that maybe wouldn't happen otherwise (anal, fantasy enactment like overt oral ejaculation where she kneels in front of them and they jerk off into her mouth and face (porn star style that most wives won't/don't do), cleaning their cocks of the residue of their most recent sexual encounter, etc).
It also allows for emotional attachments to happen, something SHE prefers, especially in longer term affairs. He longest was 11 years with her Boss/Lover, it ended due to Covid...he got VERY weird, still is. They frequently extended 2-3 day trips to a full week once they got there and things for VERY heated, especially when they were trying to get her pregnant. And they would also spend the month of December at the Corporate Condo in Florida together doing "business planning", which they did a lot of too.
Its obvious your wife WANTS this trip to happen, or she would not have brought it to your attention.........the answer would have been a HARD no to the Lover if she didn't want it to happen. If you become an obstacle to the relationship, especially one that has progressed to this level, you could easily find yourself eliminated. Better to enjoy the excitement while it lasts (and it could ramp up a LOT yet!!) and see how it comes out on the other end than get kicked out now.
