I cannot resist looking at women's behinds whenever I walk past them to see if a can get a glimpse of their underwear. At work, at the supermarket, wherever. I have a bet with myself everyday to guess what type/colour underwear the woman at work I fancy is wearing. She has lost a bit of weight recently, so her skirt keeps shifting downwards, so somedays I get a really good look. It certainly helps me get up in the morning!
