The Start of a New life part 1 [Cuckold Perspective]

Srry for the grammatical errors but i'm using traductor.

First of all I will start by saying what you probably always write, that it is a true story, but this time it is literally real and it happens simultaneously while I write this. It is my first time writing so I am sorry if the story is not very entertaining but I will just write things as they happened, without adding fantasy or emotion.

It all started last year when I found out that my girlfriend of a year had sex with a friend of his when we were just getting to know each other, I had asked her about that situation and she always lied saying that nothing happened. But finally I found out that it did happen.
I was at work on a rather boring day and I started to have doubts about that encounter, did she like it? Did he make her enjoy it more than me? Until I could no longer bear the doubts and asked her. I wrote her a text message asking her how tall this friend was, she replied 1.96 meters. For a moment I got excited thinking about how tall he was and how gifted he could be. I continued asking her how that encounter was.
Me: How was it?
Her: I don't remember much, I was drunk and it was a while ago
Me: Don't lie to me love, you do remember something.
At that moment she gave in and told me in great detail how it was, that I had her bigger than me, that I made her cum twice while I penetrated her doggy style and once on top. I have never been able to do it with my penis, only using my tongue or fingers. It devastated me to think that I will never be able to make her feel that way and I started to get hot imagining her having fun with her well-endowed friend. I masturbated right there in the bathroom at work while I was talking to her. From that day on everything changed and I became obsessed with cuckold.
Months went by and on several occasions I insisted that one day she meet someone and do it with another person and I watch, see her reach orgasm. She always refused and got upset. Until finally last week she agreed.
We created a profile on Tinder, we both have the account on our cell phone, she likes the men she finds cute and I have to talk to them so they meet the requirement of being endowed (18cm and up), they send the photo confirming and I give them my girlfriend's Instagram so they can meet each other, she can gain confidence and get together. Oh I forgot to tell you about us hahaha sorry I told you I'm bad at this since it's a true story.
Her name is Camila and she's 26 years old, my name is José and I'm 23 years old, she's in her last year of law school and I'm a computer science student, she's very shy and loving, she loves me a lot and is very tender and passive, so it's difficult to carry on this new dynamic in which I want to be more submissive and she more dominant but she's submissive with the third, that's the idea of the dynamic.
Back to the story we find a candidate that seems right, they have been talking on Instagram for a week and they have a good relationship, today will be the first day they are going to meet, they are going to go out for a walk around the city since it is summer and then they will return to her apartment. The idea is that they gain confidence and can have the first kiss. I don't think she wants to have sex right away but with a kiss it will be enough for me to be completely excited. While I write this at 17:52 local time she is leaving her apartment to meet him, I will write the second part at night with the details of the date. See you later n.n
