How I became a full-blown cuck for life as a teenager [Cuckold] [MFM]

Before reading I want to make it known this is my 100% authentic, raw personal experience with my high school girlfriend of 5 years & love of my life. I'm 23M and she's 21F, I'm white but have ethnic ties to all over the world and she's literally the hottest looking latina I've ever met who's 100% guatemalan, brown skin. I've been pretty average my entire life, being 5'10 185 lbs I never really stood out amongst the crowd, however the same could not be said about my gf, as while she is much smaller than me, she's about 5' even and 115 lbs which you may think wouldn't matter too much, but ever since I met her she sticks out a lot, and would get approached by men constantly even when I was around, which I think has to do with her cute, delicate & almost innocent look she has to her, but best believe she's anything but lol.

Around our 6 month mark in the very beginning of our relationship, she had been close friends with this dude in her neighborhood we'll call Andy. Andy was 18 at the time, maybe 6'3-5 and had a stocky football player frame, but didn't play any sports and lived 2 houses down from her (keep in mind I was pretty much across the entire city, and as a 17 year old kid with no license or car I couldn't come see her everyday). He would come over with his cousins to smoke with her a lot, which I didn't mind because they were just neighborhood friends as she explained it. Little had I known they had talked in the past and there was still tension between them, but up until this point I hadn't met him or seen them together and had no idea that they had even talked in the past. Well long story short, she cheated on me and that separated us for around a year but we rekindled and continued where we had left off, even bouncing back 5x stronger than we had been before.

But something inside me had changed.

All of a sudden probably around late 2021 early 2022 when we got back together I started heavily reading into these "cuck" fantasies on these very subreddits and I'd actually jack off to cuck porn and I wont even lie I was in complete denial when it first started, I thought it was humiliating and demasculating to like the idea of watching my girl with another man, it crept up on me really fast, but as fast as it did, I was hooked and wanted it for myself. So in late 2022 we finally got an apartment together, and after dwindling on the idea for the entire year maybe not even 2 months go by and when she was getting ready to go to bed after showering one night I first asked her thoughts on sleeping with somebody else. Her reaction was something along the lines of "You do remember why we split up in the first place and went through all of that stuff right? Absolutely not" and went to sleep shutting the idea down completely. I was a little disappointed but I didn't push it much further since it had been a long day for both of us and I was aware that my timing was probably just bad. Keep in mind she's self conscious about her looks (for some reason) and doesn't believe she can pull any guy she wanted, when she very much can. Fast forward maybe 2 weeks if even? We were smack in the middle of sex and she had told me she was going to cum, and said wittily "Imagine if you were cumming on another man" and she gave me the same look she gave me the last time I asked, except she said "You know I'm too ugly for all that right?" to which I brought her in close and told her "You are the most beautiful woman I've ever met in my entire life, so much so I would put my life savings that ANY of these men would kill to just have a chance at being with you." She started moaning louder than before and I could tell she was enjoying the validation, so I kept on, saying stuff like "you know A wanted to keep your body to himself, you probably looked so tiny riding his big ass" when I said that she rode faster and told me she was gonna cum, I told her "Cum for *A's name*) and she started convulsing so hard I felt her shove my dick out from her pussy like a rocket launcher, I had NEVER seen her do that for me EVER.

The following day we both went to work but I knew she was thinking about it all day, I knew because I couldn't get my mind off of it, sure enough when we both were home by 6 she asked me, "Why do you want to see me with another guy so badly?" and I honestly didn't have an answer. I legitimately had no idea what had got me so hooked on it at the time, but I told her "I don't know, maybe I just want to see how hot you look from the outside" or something like that, she said that we could always record our own time to watch but I told her that's not what I was asking for and she seemed to test/question me on the idea for the rest of the night until she knew I was serious. I suggested that we could make a tinder profile and we could scroll through people together to find someone. Don't think she said yes faster in her life which I found funny. She made it clear that she would choose who she wants though, and we go from there.

Not even 2 days later and she starts talking to this guy we'll call Brad, I knew nothing about him other than he's good looking, 25, white, tall, in shape and lived in a close vicinity to us, they would text A LOT and facetime for maybe an hour a day sometimes longer, talking about their lives and getting to know each other slowly but surely while I'd be sitting or laying next to her. Well 1 week forward I went to hang out with a buddy who I often had bonfires with to burn trash and stuff we couldn't dispose of easily. I came home pretty late at around 10 PM to our apartment and the door was unlocked, which was very unusual as my gf is usually scared to death of being home alone out of fear of being kidnapped and paranormal activity and keeps all doors locked, so immediately I knew something was up. As I walk into the door I hear our bed creaking really really loudly, almost as if a grizzly bear was jumping up and down on it and what sounds like her having one really long sustained orgasm she was moaning so loud. I walked directly to the bedroom door about to lay it into her for bringing someone over without asking first. I opened the door and said "Yo what's going on here" in a stern voice but there was pure silence. It was almost pitch black in the room and I could only see a small part of my girlfriend, all I could really make out was this big white lump on my bed on top of my girlfriend, and he turned his head around to see who I was, and for a split second I saw a look of pure primal territorialness on his glance but when I tell you I was not expecting this guy to completely stop, stand up and turn on the light completely naked get on the boundary of my personal space shake my hand and introduce himself to me, I was also not expecting him to look nearly as huge as he did. Standing before me a 6'6 absolute beast of a man not exactly lean, but heavy set with abs, he was 280 lbs+ and looked like Brian Shaw with hair. He just towered over me, I never felt like such a fucking child before LOL. He could sense I was flustered uncomfortable and angry at the same time and assured me that my girlfriend had told him everything and that he would leave if he wanted me to and wasn't trying to cause any issues. I didn't even know what to say on one hand I've always had trouble standing up for myself and saying no to people, but on the other hand I knew that this was what I had asked for and that I was harder than a rock staring at this guy with the thought that he was just tearing up my petite 115 lb girlfriend not even a minute prior. Not to mention, his huge dick was thicker, longer and more veiny than mine and literally covered in my girlfriends cream + was at my chest height… pretty much in my face, which he honestly probably did on purpose to size me up in every aspect. I said "You can carry on as long as I can sit and watch right here." to which he replied crawling back to her with her legs spread open "Don't worry bro I'll let you see firsthand how much your girl can take" and I no joke came in my pants watching that happen it was absolutely surreal the sounds she made validating him. These were the sounds of a woman who 100% frequently fantasized about big hunks having their way with her, and the rest was history.

I'll post a part 2 if people want a p2.

All in all, this whole ordeal has done something to my brain probably only a caveman could say they've felt before, but Brad regularly comes over as a long-term 3rd to our relationship and we both hope he never leaves and we have never been happier as a couple about to get married this spring! Everyone in a cuck/hotwife relationship absolutely needs to try something similar to this, it changes everything. Thanks for reading 🙂
