Same reason I do ;)
I know that's why my wife wears stockings to work.
My young wife developed a crush on her boss at her girls home job. No hanky or panky with the girls, though I should make that up. Instead, she wore short skirts, fastened her seamed stockings to a beautiful vintage garterbelt and gave him blowjobs at lunch. Her play with him went on for almost two years. I was made to wear my favorite cock slut outfits at home, picturing her straddling his boner and cuming wetly down over him. Before long she was coming home with him and letting me see for myself how much better his bigger boner made her feel. It was one of the most decadent times I have ever experienced.sexandgloves
