I have a twited fantasy

One of my wife's mutual friends, whom we'll call Pedro (not his real name), was very depressed because his wife had left him for another man. We tried to cheer him up, but without success. When summer arrived, my wife and I went on vacation to the coast and decided to invite him to the apartment we had rented, which had two bedrooms. During the day, the three of us went to the beach, but at night my friend didn't want to go out with us.
On the 3rd day, Pedro quietly asked me if we could make less noise when having sex with my wife at night, because she could hear us from her bedroom and he had to end up masturbating in order to .......
I apologized to her, and I promised that we would do everything in silence.
But after a moment I asked him if he masturbated thinking about his ex, and this time it was Pedro who apologized, saying he did it thinking about my wife. I was speechless, but I admit I liked that he got aroused imagining my wife naked.
I told her everything and she was surprised. She asked me if I'd like her to ...... with Pedro. Imagining that situation excited me, and since I was wearing shorts, she noticed. She smiled and said, "I guess I'll have to help your friend out of his depression then."
My wife suggested a game to "lift her spirits"
I would suggest a card game to Pedro. If I won, Pedro would pay for dinner at a beach restaurant for my wife and me. If I lost, I would do the same for just the two of us.
And I want to make it clear that I was supposed to lose.
So I did, my friend agreed, and I lost.
That night, my wife dressed in shorts and a somewhat see-through black t-shirt that she only wore at home with me because, as she said, it "showed too much." When I saw her, I got an erection. She touched my crotch and laughed, saying, "Tonight is going to be very hot."
They left in my car and I was aroused and wanted to masturbate, but I resisted. After dinner and wine, I fell asleep.
They returned at 3 a.m. Five minutes later, in the bedroom, I asked her to tell me everything. She said that Pedro, two blocks away, stopped the car and told her that tonight, since everyone at the restaurant would think they were husband and wife, he had to rehearse, and then he kissed her on the mouth. She was surprised and accepted.
A
Two blocks further on, the scene was repeated, but this time, they intertwined their tongues.
As they got out of the car, he kissed her again and touched my wife's buttocks. Arm in arm, they went into the restaurant, had dinner, and then walked along the beach. There, lying on the sand, Pedro ran his hand up my faithful wife's legs and caressed her inner thigh. But my wife's hand wouldn't let him slip under her shorts.
Then he lifted her shirt and, pulling down her bra, licked and bit her breasts. My wife moaned and enjoyed it while she masturbated Pedro after unzipping his pants. Pedro didn't last long and came with a shout. My wife said enough for today and asked him to go back to the apartment. When they arrived, they got out, kissed again, and each went to their own bedroom.
I wonder if he was angry.
I pulled down my pants and showed my rock-hard penis, about to explode.
She said, "Take me, I can't take it anymore."
And I told her no. Tonight, your husband is over there, pointing to the other bedroom. Go and do what the three of us want.
That night, I was the one who masturbated while listening to my wife's multiple orgasms, from the next room.
