My wife when we were newly married

Hello, my wife and I have been married for about 21 years, she is 39 and I am 42. When we were married for about a year, due to immigration issues, they sent me to MX for a few months. We went to my town where only my grandparents lived, already elderly, and no one from her. We went to live at my parents’ house, where she was alone. I started working, she stayed at home. A childhood friend who was well off financially gave me a job. He would go and drop me off at work, he would also pick me up. In the afternoons he would almost always stay there with us, playing cards, having dinner, things like that. One day I went to the little store and left them alone. I saw through the window as he was walking that he tried to kiss her, she pulled him towards her, but she pushed him away too and went to the bathroom. I don’t know why I stayed quiet. He said, “I have to go.” She came out fine. Then one Friday, my friend and I went to another friend’s warehouse to drink. 2 o’clock we went to the house already drunk, my wife was on the porch with a little dress on I saw that she was looking at me and I asked her do you like her right he told me she is very pretty and good I told her and she told the truth yes we got off, they knew how to play cards in bed and I gave her beers like she had never drunk they got on her, I started to touch her tits like this from behind she first stopped my hands then I made signs for her to touch her friend’s legs, she let go, he moved to kiss her and she took him by the head I took out her tits, he lifted her skirt tried to take off her underwear but she had her legs on the mattress I lifted them up and he took them off, he pulled down his pants I stopping her from behind he tells me she turns off the light I turned something off but it could be seen, she lay down on the bed face up he put it there he rubbed her then little by little I put it in her watching how he was entering he began slowly then stronger each movement of his she lifted her breasts she buried her nails in his back, he began to suck her tits and more she moved and moaned she hugged him with her legs, a little while passed I saw for the first time that she came like this face up trembled gave some screams wanted the friend to stop but he still didn’t come he gave her a little more harder and she moaned again he pulled out she grabbed her vagina and moved to the side, he went to the bathroom, she got up I tipped her I put it in her but she said I can’t, I only with my hand I threw it there on her back she also went into the bathroom, there I began to feel something strange I don’t know what, he left, we went out to the patio he said I’m leaving, I stayed there when I entered the room she had fallen asleep we were like 6 months there she stayed alone and he didn’t work, she came pregnant from there and he is the only son we were able to have. My friend was murdered a short time later. I was able to speak to him on the phone shortly before, I couldn’t go to MX.
