From my freshman year in high school and even in the Army, nearly everywhere I went I managed to cum in women's nylon panties. The opportunity's were rather endless as in going to parties with my parents, over to relatives homes, my mothers panties, my sisters panties, my aunts panties and especially exciting was using my friends mothers panties, neighbors panties, girlfriends mom's panties even girlfriends panties.
I never stole any ones panties and always put them back into the drawers. I would usually say I needed to use the bathroom and if no one was in the back part of the house I would sneak a pair out of the woman's' drawer and have my fun usually right in front of the drawer or in the bathroom. Sometimes the woman's panties or slips were drying in the bathroom so it was a piece of cake. I never got caught with the exception of my mother, but that's not part of this story.
In the Army friends would invite me over to their parents some times it was a week end away and back. I would say I was tired and needed a nap and they would put me in the master bedroom or the guys sister's bedroom. Then I would leave my mark. I even did it after I got married, normally at my wife's parents house, usually every one was busy and it was easy to quickly jack off in my mother in laws nylon panties, she had beautiful lingerie and I never tired of dropping a load into it. As far as I know, no one except my mother knew.
