We love going shoe shopping for Kate in a short skirt and no bra. That is great fun.
We also enjoy finding the stores with dressing rooms that only have a curtain instead of a door. Kate will leave the curtain partially open (accidentally, of course). She likes to give the bored hubby's there waiting for their wives something to look at while they wait.
When we can only find dressing rooms with a door, Kate will put on scandalous outfits and come out and model them for me (and the other hubby's nearby).
Kate wears low-cut tops with no bra, and we find a sales-man working behind a counter selling jewelry or watches or cameras, something Kate has to lean way over to examine in the showcase. Kate will lean over, giving the guy an unobstructed view down her top, and ask him a lot of questions. letting him look for a really long time.
We also like to find all-night convenience stores with no customers and with only one guy working behind the counter. I park right in front so I can watch. Kate will go in wearing only a coat and heels or a really short skirt and see-thru top. She will nonchalantly put on a show for the lonely clerk.
