Once while shopping in a big department store I asaw this couple walk past. She had an extremely short skirt and as it swung I thought I caught a glimps of bum cheeks underneath. Anyway they then went up the escalator which had glass sides, so I positioned myself appropriately and there was no underwear in sight under her skirt (unless it ws a really tiny g-string that had got lost inside!). She had the most beautiful rounded bum. As they eventually went up two further floors, I checked twice again and could still see no underwear.
Anyone else enjoy escalators?
