[MF] Cheating coworker takes cum (found not mine)

It was about 2 months into a new job I had gotten in a small office. It was just my and 3 women in there, two in long term relationships and one to old for me. It was a normal office job where I had an office and my own space. The job itself was challenging and I was beginning to feel like it was too much work. The days seemed long and when I got home I would think about work all night. One of my coworkers J took the bus with me in the mornings. We began talking and building a work related relationship. Halfway through a terrible week J texts me that she is cold and I tell her she needs a dog to keep her warm when she replies “or you can keep me warm” I know she has a boyfriend but I also havent gotten attention from women in a while. I feed into it because shes not too bad, a bit over weight but keeps it mostly in her chest. I tell her “you can show me some of those yoga moves you’ve been practicing” and she says “It wouldnt be hard for me to bend over a desk for you” This girl keeps upping the ante, if I say something she goes one step further. I cant take it anymore so I tell her “my balls hurt from the huge load I have for you” I cant believe I’m having a conversation with her like this. After work we continue sexting and eventually send each other nudes. I make her send me a picture to make me hard before I send a dick pic. I wait with anticpiation and finally I receive a picture of her massive tits. Shes pushing them togeter and I can finally see her figure. I send her a picture of my now hard dick and shes about to lay eyes on another mans hard penis. She loves the picture of my cock making me fucking hard and tells me she wants me to cum to her. I film myself blowing a load to her pic. She went from being my normal coworker who loves her boyfriend to texting me encouraging me to jerk off to her. We say we are going to fuck in the office and plan to after we get there, but she claims to miss the bus but I knew she was actually deciding not to cheat and bailed. The next day is more of the same except the second day she tells me that she wants me to cum inside of her. Before I was just saying things like it would be hard to pull out if I had to. Friday was getting more and more hot and now its obvious she has the same fetish about making me cum as I do about cumming. She says she wants my thick cum leaking out of her and I tell her that just makes me want to cum as hard and as deep into her as I can. At this point it is obvious we are going to fuck. I keep saying things like “Its going to feel so good as I pump you full of all this cum” and she keeps saying shes ready to receive my load. She eventually asks me where I live after saying she would come over friday night. I am excited and tell her and ask her if shes coming over and she says not tonight but maybe tomorrow. I say we can smoke weed together trying to entice her to come over for something other than just sex. 10 minutes pass…
