[Slidingdown]

I thought I would share a story of mine happened a few years ago.

A new coworker started at our company. This was her first job. We were field technicians so dress code was jeans, button shirt and decent shoes.

Anyway, after the introduction, I went outside to have a smoke. She joined my outside and we were talking about the days work and how she will be shadowing me for the next 2 weeks on the road.

As I lighted my smoke, I noticed that her zipper handel on her jeans was pointing straight out and her zipper was approx 1cm open. It did not seem that her jeans had the little cover flap behind the zip, so I could see her bear skin.
I knew that the zip would eventually slide down, so I kept my mouth shut, keeping an eye on the zip without her noticing.

As she talked and move, I could see the zip slowly sliding down. It was at the point where I could start seeing her bright blue lace panties.
The zipper was about halfway down at this point. I decided to light another one, and as I put the light away, I made sure no one was nearby, and then told her that her zip was going down.

Very embarrassed, she looked down saying "oh shit, sorry", zipped up her jeans but left the zipper handel pointing straight out again, but this time the zipper started going down almost immediately, revealing her blue lace panties again. This time I waited for the zipper to fully open.
As we were about to go back into the building, I told her again that ther zipper had go down. She apologized saying "I'm so sorry, I am sure that I zipped it up", very embarrassed and pulled the zipper up again, again leaving the zipper handel pointing straight out.

She then said I" doesn't know why it keeps coming down" (I knew), but I knew that this was gonna be a great week.
I knew this was not intentional so I felt sorry for her, and said "you might wanna keep an eye on it and make sure it is zipped up all the way". She asked "is it not?", which I replied "I can see your panties".
She reached out again, zipped up, but this time the zipper handel fell down locking the zipper in place.
"I am really sorry, I will keep an eye on my zip" she replied looking very embarrassed.
