She Devil

I’ve been working with my coworker for a while now since she was 18, and slowly she has started talking about her personal life. We talk about sex at times and joke around about things but I def tell her what I’ve done with a few exes. I think it’s opened her eyes quite a bit sexually lol. I’ve done some qinky things and I felt she was wanting to try it at home. So one time she told me she’s been getting very horny and her man which I’d assume is her bf at the moment wasn’t cutting it. When she got into the truck in morning we started driving to the gas station. She right away started laughing and said I finally did what I wanted and that I’d be proud. Before I could ask what she laughingly said “I just woke up to my alarm clock and rolled over, and he has a morning hard on through his boxers. So climbing on top of him I pulled my thong to the side and as fast as I could without him waking up slid him in me. I spit in my hand and stroked him wet so it wouldn’t hurt. I swear I didn’t last three minutes riding him and I had an orgasm. As he woke up I got off him put on some pants and left him wanting it.” She then went into the store, like was she serious? I messaged her to grab me some gum and her phone lit up in truck. She forgot it and I looked and a person messaged her asking what’s gotten into her. Wth did she actually do this to a guy this morning? Is this 18 year old a she devil I call them??? I wanted to test her so I told her that day that it would be crazy if she let him finish also then run to work right away to start the day haha
