So hot chum!!!
I've been fortunate to have coworkers in the past like that as well!!!
And, I've gotten soiled thongs from 3 of them at different times when we've gone to conventions! I still have them, of course!
And there was another hot coworker that sat at a desk next to me who used to go jogging at lunch. One time after a jog, in the afternoon, she stepped away to use the restroom and I dove into her bag of workout clothes that was under her desk! I almost passed out when I felt something stringy - and pulled out a tiny, completely moist pink g-string!!!!!
It was too good to be true, so I said "fuck it!" and tucked it into my sock and brought it home for an epic sniff and cum session!!!
I have that one still too!!!!!
