I loved the reply about 'Why are you looking at my butt?'. I did have something similar happen to me. I was working with a small crew of men ( me and two others ) repairing a leak in a water line. We had dug a deep hole to get to the buried line and then had to remove caked on mud from the pipe to determine the extent of the damage. So here I am down in this hole in shorts and t-shirt and my panties. Naturally the t-shirt rides up a little and one of the guys, who was half drunk at the time, yells out 'are you wearing your wife's panties?' I was so shocked and embarrassed that I did not know what to do so I did nothing. I acted as if I did not even hear him. He did not make any more commments and the first chance I got when they were not looking I tucked my shirt in after pushiong my panties down a little. I wish had thought of the come back but I guess silence worked okay too.
