For once I'm not working from home. I'm in the office and it's practically empty (thanks, omicron).

The only other person in the office I can see is a girl I don't know. I noticed about an hour ago that she's not wearing a bra. Her top is opaque, but the shape of her breasts are pretty clear. I'm pretty sure I would have noticed something like that earlier as she's pretty enough that I've checked her out a little. I can only assume she was wearing a bra, but has taken it off.

As soon as I noticed that, I immediately took it as a challenge, and snuck off to the bathroom. Now I'm sitting here pretending not to notice her breasts, without a scrap on under my dress. I have no idea why I felt the need to react like this - but I'm loving it.
