Casually flirting & sliding into my GF's ex-roommate

Jess (37, married) was my GF's neighbor growing up, and eventual 1 year roommate years after, by a mere convenient happen stance of events and location. November 2020- She texted my GF to say she was back in town from Wyoming for the Holiday, would stop by to visit, and had gotten her a present that she wanted to drop off. My GF actively had COVID at the time, and was quarantined at her apartment across town. Jess wasn't overly concerned by that, but my GF cautiously pushed back and in doing so made the feeble mistake of suggesting that if she insist on gifting her, she could instead drop the gift off at my apartment instead, which logically was in fact several miles closer to where Jess' family lives. Jess wasn't aware we lived separately until my GF informed her. Shortly after my GF gave me a heads up call about her impending arrivaI. I know Jess, but rather vaguely, and mostly just in passing. However I was fully aware she is attractive, hoped she thought the same of me, and so would then perhaps arrive alone without her husband. She did in fact come alone, and then we came together. Great fuck. Her goal thereafter was to stop over once more the following morning before they left town, but her and her husband ended up heading back home later that night. I'm assuming he didn't see her get dressed earlier that day, being that he would have reticently noticed that she no longer had her panties on (or at all) after getting home. They were drenched with cum, slowly drying out in my bedroom waste basket by my computer desk. The gift she had bought my GF was merely a 20 dollar Amazon card. In the video clip I flirtatiously was asking her if the 20 dollar card was worth the trip, as I casually made my initial insertion pumps. She pleasantly admitted throughout the session that it was well worth my dick and cum in return.
