I have always had a fantasy of being cuckolded by my wife. But my wife, being of the very vanilla type, never showed any interest in it. I had, however, from time to time told her that she could have "other boyfriends" if she so wished, which she waved off and didn't show much interest in.

About a month ago, once again I casually raised the point, but this time she didn't wave it off immediately but joked back, "Maybe I will when you are gone. I thought she was joking and didn't take the topic any further. Through work, I have received a visa to shift to another country and am in the process of wrapping up everything here before leaving. My wife, however, would be staying back for 6-8 months and joining me after. So before leaving, we were catching up with old friends and relatives. My wife is still friends with two of her ex-boyfriends. So we had also gone to meet one of them about two weeks ago. He congratulated me on the new move and assured me not to worry about anything back home, as he would be available for any help if required. He even took my number and told me I could reach out to him if any support was required. Around 2 days after the meeting, he casually texted me, and after some general discussion, he diverted the topic towards my wife: where she will stay and travel, and are her tastes the same as they used to be? Slowly, the topic moved towards being a bit more sexual, like her tits seemed to have grown since she was with him, etc. Initially, I was a bit offended, but I knew he was her ex, so I replied to all his questions. I didn't tell my wife anything about this. But just yesterday she herself jokingly said that after I'm gone, she might consider having an affair.
