story about two waitresses and their buttons?
 

I'm hoping someone has a pointer to a story I read a long time ago and haven't been able to find. It starts out with a guy who I think owns a restaurant or bar and two women. One of them works at the restaurant/bar and the other is attached with the guy somehow. The guy has a bunch of Japanese businessmen coming in the next day for a private party and needs extra help. The girls experiment with how many buttons on the blouse show off how much.

The next day, party happens and the girls unbutton blouses, remove bras, panties, with predictable fun results.

Anyone recognize this? Have a link?
