gf (23) got fucked on the first day of her Europe vacation [cuckold] [cheating]

My girlfriend and I have been dating for almost two years (she actually will be gone during our anniversary), and she is headed to Europe with her family for christmas time. She got there yesterday and decided to go clubbing with her sister who lives there that night. Now me and her had vanilla sex our entire relationship until recently when she discovered my cuckold fetish through my reddit. At first she was super mad but eventually she started bringing it into our sex lives talking about her wanting to fuck bigger cocks and stuff like that. However, I never thought she’d act on it.

She told me her plan of going to a club with her sister right before I went to bed due to the time change, and I told her to have fun and stay safe. The next morning I woke up to so many videos on snapchat from her which was out of the ordinary. I was so shocked when I opened the first one and saw her making out with some random black guy at the club she went to. I could even see her sister watching in the back which was so embarrassing. She captioned it with “your wish is coming true tonight baby, this guy asked me to come home with him”. My heart sank immediately but also i instantly became the horniest I’ve ever been. I watched the video of them making out for a while because I was so nervous of what was to come next. After a bit I clicked on the next video and saw it was my girlfriend on her knees with her tits out of her slutty dress sucking the guys huge cock. I am no small fry being around 7 inches, but this guy had to be 8 or 9. She locked eyes with the camera while the guy was talking to her calling her a good slut and asking if his cock tasted good. It fell out of her mouth and with spit going down her chin she said so much better than my boyfriends, which almost made me cum in my pants barely touching myself. I was so conflicted because I was caught off guard, but I became excited because I knew what the last video would be. With my heart racing I opened it to find a video of her screaming in ecstasy as he stretched her pussy in missionary without a condom. I could visibly see her cumming repeating on his cock as she kept saying things to degrade me. The video ended with him cumming inside her pussy and her sticking her fingers in it licking them clean and then saying she hoped I enjoyed the video. It was the hottest and hardest thing I’ve ever watched. The girl I’ve loved for two years getting used by some random guy. She also have never let me cum inside her before and he did on the first time which was so humiliating. I called her immediately after cumming myself but she said she was busy and sent me a picture of her in naked cuddling with him. She said she’s gonna call me after she get used by him one more time and heads back to her sisters place. She apologized for not asking but I immediately forgave her because now I know for sure I am meant to be a cuck. I always wanted to post on here and now I finally can.
