Strange Request

Maybe I’m over thinking this maybe I’m not. I have been working here where I work for almost 8 years. Right out of college came here and started my career. I met a women we flirted had a fling that latest about a year. Towards the end of our fling we slipped up and she ended up pregnant. I freaked out she was obviously the level headed cool one between us 2. See she has been married for a couple of years. I know it’s bad and she was married but she checked all the boxes was very willing to experiment and try new things. She let me do a lot to her push her to her limits. We got sloppy but never got caught just got pregnant. She ended having the baby a boy and letting her husband think it was his. She left to stay at home and we kept in touch. It was very difficult to keep seeing each other with the baby in the picture and we went on our way. Occasionally I would her from here and we led it at that. Fast forward a few years and I get a call from her. Wants to talk and if we can meet. Ok I agree to meet her for a long lunch and off I go. She’s by herself says thing are great her and her husband have a routine he still doesn’t know but she has a favor to ask. She shows me pictures of the kid and he is a very handsome little guy. Looks a little me when I was his age. Kind of weird but ok I ask what’s up. She states that her husband her have been talking and would like another baby. Ok what does that have to do with me. She tells me that she gets compliments on how gorgeous her son is and thinks that we made great babies. She wants me to knock her up. I didn’t know what to say instantly she starts to send me pics nudes says that I can do what I like to her if I can knock her up. I ended up getting rode hard during my lunch and for the next 3 days after we met she would meet me at noon on my lunch and blow and fuck me. She has stated that she know remembers how great it was when we fucked. I ask does your husband suck or something she says yes 2 pump chump. I never agree to what she wants but having sex with her again brings back memories how great she actually was. So now what I ask her.
