This goes way back, but the memory is still vivid and worth retelling.
N (25F at the time) and I (27M) were colleagues and next-door office neighbors (yes, office, not cubicle) in a smallish department of a large company.
N was very attractive–5’10”, short dirty blond hair, green eyes and freckles, with an athletic frame, long legs and probably 34C breasts. I’m 6’2″ with a lean athletic frame. She liked to talk about her weekend escapades and was never afraid to drop a sexual innuendo into a conversation.
The company had it’s own full-service cafeteria and on any given day several of our group of 6-8 would go down there for lunch. After she had been on board for a few weeks, we were sitting at a rectangular table for six with her across from me. As I was about to take a bite, I felt a stockinged foot slide up the inside of my pants leg. We immediately locked eyes and she had an impish look on her face. I did a pretty good job of not reacting in a way that anyone else would have noticed anything.
