I [m24]found old amateur porn videos of my [f25] gf and Idk what to do?

For some context I have been dating my gf for 2 years and it has been the best 2 years of my life. She is a law grad and is extremely smart and intelligent and matches me perfectly. Shes also beautiful, a former college swimmer with blonde hair, big DDD breasts, a fit body and a huge ass with wide hips and thick thighs. Legitimately my dream woman. When we met she told me she had a pretty high body count but the wait she could perform in the bedroom made it all worth it. I jokingly used to say she gave me the “pornstar” treatment. She knew every trick and even did anal for my birthday.

Last night I was watching porn on a shitty website when I saw a chick with a fat ass getting fucked in doggy. I was jerking off to it until I saw the chicks face and she had the same nose ring and had her eye brows done the same way. I continued to watch until the guy flipped her over in missionary and it was 100% my gf when she was like 21. It was filmed on like a shitty phone camera so the quality wasn’t amazing but it was 100% her. He fucked her in missionary and she was saying super dirty shit and moaning, her big tits bounced the whole time and I was in shock. I watched until he pulled out and came all over her face, mouth and neck. She giggled the whole time and then the video ended. I kinda just sat there staring at the screen until I went to the profile of the poster who just seemed like a bot or something that reuploaded a shit ton of porn. I found more and more of my gf because they used the same tags for each one everytime, all with different guys. Some were more professionally shot which seemed like she was with an amateur male pornstar, some were solo videos of her and some were 100% hookups with shitty cameras.

I found maybe 40 videos all with different men based on their dicks. Though I think 3-4 were the same 2 black guys tag teaming her. Some recorded by the guy, some by her, some set up the camera pointing at them, some even seemingly recorded by someone else. Like 10 were even what seemed like in her dorm in college. I even saw one that I am pretty sure was her guy friend from college that they had a quick “fling” in senior year of college. She was taking back shots from him on his big and I mean big white dick. He had her bent over a chair and she was in her sports bra and he was clapping her cheeks while she pulled her tits out of the bra and the flopped in rhythm with him.

One that really stood out was this latino guy getting head from her talking dirty the whole time in what I think was her dorm. She was slurping all over him and deepthroating him and calling him “Papacito” eventually it ended with her bouncing her ass on his dick and he busted inside and on her cheeks. Another wicked hung guy. She was always very vocal during the sex and the guys matched it with dirty talk. It was super humiliating to watch. Different places, different outfits, lingerie, stockings, high heels, cosplay. A few of them seemed like they were taken while we was an exchange student in Brazil especially one where a guy was wearing a Brazilian national jersey while fucking her doggy and speaking Portuguese to the guy behind him recording it on his phone.

One even seemed like it was at a frat party since there was music faint in the background and a few dicks showed up in frame to get sucked while she was in missionary with a guy then left after a few seconds of sucking kinda doing bro giggling. The worst one was a guy maybe 50+ who she blew and let fuck her with this giant hairy dick. The video must of been like 45 minutes of her moaning and yelling as this big, pot belled old guy fucked her in like 5 different positions before nutting on her face.

There were only condoms in these like 50% of the time…

I was pretty much speechless. This was my gf and she was basically a slut. And thousands of people had seen her take loads and dick. The last one I saw was a PMV of some of her videos made by an anon user. Cut together to a song ending with a compilation of her taking loads in different locations. Her hair was a different color in many of the videos but it was 100% her.

I closed out of the website and called her over to talk. When confronted she admitted she used to be “kinda a hoe” and used to love to be filmed. She hooked up with lots of men in college and even some amateur pornstars for their channels. She said she used to post them anonymously but eventually took them all down. She said she isn’t like that anymore and wants a future with me. I told her she and I had had sex while she was wearing cosplays she had been tag teamed in. She said it didn’t mean anything and that ours was still the most special. And to please try not to let it make me insecure. I said I needed time to think.

I feel like a cuck watching all those videos and felt like this was the best place to get this off my chest. Any advice?
