Longest Time Spent Nude

When I was fourteen, my family visited a naturist camp managed by a college friend of my mother's. We were there a total of eight days, and I never wore a stitch the whole time. The nights were warm, so even then there was no need to wear anything.

 

No one was home for a long weekend, I was naked for 3 1/2 days, If you want to count putting on a tshirt and shorts to go get the mail for 45 seconds, then I wasn't.
