I was 17 when my friends gave me bare butt birthday spanking. Almost died when they pulled everything down and got my 17 swats in front of girls telling them to flip me over. Got held face up over a table while girls went crazy looking at my dick getting hard. I guess my stopping to struggle was what made them decide to strip everything off. Spent more time naked that I would have wished for, but erotic and exhilarating at the same time watching girls enjoying themselves. The worst was knowing these girls personally and having to endure all their teasing and comments and knowing they knew exactly de size of my penis.
