A few weeks ago there was an evening get together at work, after a while I noticed that an attractive coworker(she is in her early 20s, curvy body, big boobs and ass) had forgotten to close her zipper (she always wears jeans with long zippers so it was it quite obvious). What made this special for me is that I had always been fantasizing about her forgetting to close the zipper but she has been in the work team for several years now and until that evening I had never seen her with the zipper open so I thought that unfortunately it would never happen, so it was a nice surprise when I noticed that she forgot to zip up. Of course I got turned on very much by the view of her open zipper and didn't tell as not to spoil this opportunity. Apparently, no one else noticed that her zipper was open (or if some people did they probably were too embarassed to tell her) and so she spent several hours with her zipper completely open, giving me enough time to fully savour the view hehe
After a while of sneaking glances at her open zipper I was turned on so much that I intentionally "forgot" to close my zipper after going to the bathroom, I am not sure if someone noticed my open zipper (at least there were no obvious reactions) but I hope that the attractive coworker did, who knows, I like to imagine that she saw it and liked the view hehe
I will probably cherish this zipper moment for a long time, it really made the evening for me
