This is tame from this sub's standards but I often think about this and wondered if anyone would else would enjoy it. I was friendly with a coworker in my last job, and we used to text outside of work as well.

We would lightly flirt but both of us were married and never pushed it too far. One time she texted me an image of a messy bed which had her laundry strewn all over. I caught sight of her pink panties in one corner, and told her there's something here which I really like.

She was playing coy and made me type out that I was referring to her pink panties. Once I said that though I felt as if I crossed a line and started apologizing.

She told me not to worry about it and that she'd wear it the next day. At work next day, I asked if she was wearing it and she nodded yes, and it started a new tradition for us ;)
