There have been a few times over the years when I'd be out running errands with thick, drooping wet cloth diapers and plastic pants under my shorts, when I'd really feel daring and take off the shorts, then hop out of the car to go drop a letter in a mailbox or put gas in the car. On a few occasions I've parked the car, gotten out, walked over to a drink machine, bought a drink, then gone back to the car. I definitely got some interesting looks--usually middle aged women who got this big grin on their faces because they couldn't believe it.
Once I was doing this, putting gas in the car at a filling station in a t-shirt, sagging wet and loaded diapers and Lollidots plastic panties. A car pulled up to the pump on the other side and a teenage girl walked over to me and asked if I could loan her a few dollars. I said "Sure, hang on" and finished filling up the car, then put the hose back, got back in the car and sat down and got out my wallet and gave her a few dollars. This was one of those moments that are just surreal--when one of your biggest fantasies is coming true and you just can't believe it, and at the same time she acted like she was paying no attention at all to the fact that I was wearing a t-shirt and wet poopy diapers. I thought "well she probably couldn't tell that I'd loaded them" then I got home and looked in the mirror and there was poop shooting out the legs of the plastic pants and it was completely obvious.
Usually I don't do this sort of thing--too risky. Alas, that's one of the bad things about people having cell phones. Back in the days before cell phones, I was a lot more risky because people didn't then have the ability to immediately call the cops or take pictures. And when I do it, it's always on a very hot summer day--those are my favorite days to be diapered, also, if confronted about it I'd just say "Well I have to wear them due to a health problem, in the summer I don't wear anything over them because it's too hot, and sometimes I just forget about it because I do it all the time..." Or something like that.
