finally cucked by my ex (true story)

Long story short my ex of one year broke up with me this summer and after a few days she hooked up for the whole month with a guy thats been dming her on instagram. I found this out when I tried getting her back in September and also asked details of what they did. Heartbreaking details but the cucked inside me was livid. Stuff like she let him ride her anally, something she only attempted once with me and couldnt do it, came inside her even though she never let me do it and overall be at his disposal. After this heartbreak we broke up for good and I couldn't get the details out of my head. I found myself jerking off to sleep, waking up with dry cum on my belly night after night imagining she was getting the shit fucked out of her by a real man.
I wanted to tell her about this fantasy so that she can cuck me for real and I did, I messaged her saying I wanted to meet. I bought her a red lipstick that doesn't stain, forums said its best for blowjob, Maybelline vinyl ink and also a black lingerie set. I gave it to her, told her about my fantasy and that Id like her to use these with her now fuck buddy.

Mind you this is december, a few months have passed since september and he's still her regular.
She was weirded out but I started telling her about why I am into it and about how it helps me and she agreed to use them. She said she won't take any pictures, but will let me met her before he comes over to see how she looks like with the red lipstick and black lingerie and she was Godlike.

I got on my knees and kissed her ass and tried touching her pussy and she slapped my hand. She kicked me out once the guy was in the area and instead of leaving, I waited in the building, for him to enter her apartment and then kept my ear locked to her apartment door like a fucking weirdo. I could her them fucking for an hour and heard him saying "I gonna cum inside your asshole" and heard him groan so hard and her moans through the door and I waited one more minute before I left. I texted her asking how she is and she hasnt replied to me for one hour after they were done, but when she finally did she said she s good, didnt give me much details over text, but I feel like this is a very good first step.
I want her to one day let me take a look.
