That time a trip to the turned into a hot ??[MF]

I’m an attached 41 year guy for context. This happened a few months ago when the malls opened back up after quarantine. I frequent the Spencer’s at my local mall as a time waster and to get funny/goofy stuff for gifts and such. “Deb” is one of the managers there. She’s super nice and always helpful. She’s also very attractive. If you cross cloned Rosario Dawson with Kerry Washington that’s pretty much what she looks like. Big brown eyes with beautiful lips. But with an edge to her. She’s also tatted up and has a few piercings. We’ve chatted a few times along with some harmless flirting. One thing I’ve always noticed was she was constantly wearing baggy clothes. Sweatpants and hoodies so i never really paid attention to her body. On this particular day she was in jeans and a T-shirt that really accentuated her curves. Her tits were huge! I was doing my best to not ogle when she came over to chat. “Hey you! It’s been awhile since you’ve come to see me. Looking for anything in particular?” “Nah just browsing. And staring at you!” I said as we both laughed. We made more small talk. I’ve always been of the opinion that you shouldn’t read into salespeople at retail stores being nice to you. It’s their job right? You should never hit on them. But Deb and I had always talked and this conversation got a bit more intimate. She had broken up with her bf and was confiding in me. Apparently he had never really taken care of her in the bedroom. I told her he was crazy. That she could probably have her pick of anyone to dick her down. She smiled. And then she proceeded to tell me that she always has a thing for me. She knew I was attached. And told me that she wouldn’t say anything if I didn’t. We exchanged the proper app info and proceeded to have a week of steamy texts/pics before she said that she wanted me to come over the following Friday night
