[MF] Great hotel sex with my hot coworker.

I have this female coworker. She is new to her position in the company, so I have been training her. We work in different locations in opposite parts of the state but since we have the same position in our locations I have to show her how to do the job. We mostly talk through text and email but have met up a few times. She’s a little younger than me (she’s 24 and I’m 30). She has a very athletic build, skinny but toned. She always works in blue jeans with a 3/4 sleeve top, wears flats and keeps her dark hair in a ponytail. She also has a tattoo on her arm that goes from her wrist up underneath her sleeve. I kind of get a punk rock vibe from her. She is definitely attractive, but I hadn’t given it much thought beyond that. She is married to a serviceman, but according to her it’s for convenience, not love. They basically have an open marriage.
