I've seen thongs on a couple of ladies here at my work.. very exciting! I've also seen the same thing at sporting events and such. Always a thrill to get that sneak peek!
By the way Zonetime32, I think there is a big difference in seeing your sister as a hottie and acting on it. I think as long as you keep fantasies as fantasies and don't become obsessed with her that's not that strange.
