I had already been insisting for some time, especially in moments of heat, that I would love to see her with another man. She always told me no, asking why? That it would only bring problems, that I was more than enough in bed, and that she didn't need anyone else.

Time kept passing, and her answer was always the same. A couple of weeks ago, she and I went on vacation to the Caribbean, just a normal trip as a couple without any particular expectations. By then, I had even forgotten about the whole thing and hadn’t brought it up in a while.

One day, a Saturday, we were at the hotel's beach, and near us, or maybe right next to us, a foreigner sat down. I noticed that he was looking at her a lot, especially at her feet, and that turned me on a lot at that moment. I also saw that she glanced at him a couple of times.

After a few minutes, I offered him a beer, which broke the ice, and the three of us started talking—just normal conversation about our lives, etc. I know her well, and I can tell when she's flirting, and honestly, she got pretty flirty with him—smiles and all—but nothing too hot or over the top. He was also quite flirty with her, but overall, we just talked for about an hour. Then we went our separate ways—him his way, and us ours.

While we were having lunch, I asked her directly, kind of jealous, something like, "Hey, did you like that guy?" And she was like, "Nooo, not at all, he was just a really nice guy, but nothing else."

That night, she and I went out for drinks at a nightclub in the city, and after spending some time there, we ran into him again.

That night at the bar, it was the same thing—she was flirty, and so was he. I let them dance a little, but nothing too crazy was happening. When it was time to leave, and considering he was staying at the same hotel, we decided to share an Uber.

As we were getting into the car, since it was a small one, she told me to sit in the front next to the driver, and that she would sit in the back with him. During the ride, I noticed they were flirting again, and at one point, I saw them holding hands and whispering things to each other.

When we arrived at the hotel, he told us he had some liquor in his room and asked if we wanted to go up and continue drinking and talking, saying he really liked our company. We agreed and went.

At first, it was just that—we drank, talked, and the flirting between them continued. At some point, I had to go to the bathroom (because of all the beer), and when I came out, they were on the balcony kissing. It was more of a tender kiss, nothing too hot, and when they saw me coming out, they separated and walked back into the room.

We kept drinking, played some music on the phone, and at one point, she sat on his lap as if they were a couple and I was the outsider. They held hands again. After a while, and quite openly, they started kissing more intensely while dancing.

At one point, he had to go to the bathroom, leaving just the two of us, and I told her directly, "Hey, if you want something more to happen with him, go ahead, but I need to watch." She looked at me and stayed silent.

As soon as he came out of the bathroom, she threw herself at him, and he reciprocated. They started undressing each other, and, well, I feel like she had the best sex of her entire life that night. The positions they did and how much she enjoyed it were indescribable.

By around 2 AM, at one point, when he went back to the bathroom, she told me, "I think you've seen enough. I'd like to be alone with him and have some more intimacy with him. Please go to our room, and I'll come later."

She ended up coming back to our room almost at noon, glowing, beautiful, as if she had been reborn. She simply told me, "Thank you for trusting me," and that was it. The foreigner left for his country that same day, and we continued our vacation.
