A couple weeks ago, I was in the observation car on Amtrak. I had sun glasses on and pretended to be asleep. I had been reading literotica so I had a huge erection and tight slacks. Three little girls between 11-13, were running the isle and each time they went by, they would stop and gawk at my package. I turned on my screen video camera to secretly see thier expressions. They surely got an eyeful. Seeing is believing and I noticed that the oldest girl had to change cloths. I wonder why?
