This seems to me a little creepy at your present age. You can purchase your own. This thread really creeps me out and I rarely speak out to individuals turn on's.
I have worn my mom's panties and used pads together when I was a teen. Sixty years ago there were not any disposable pad productions for women and babies, so women and babies had to wear handmade cotton and fabrics pads that were washable to use again and again. It was a great chance for me to wear my mom or sister's menstrual cycle used pads and panties to wear and wank off. It was incredible.
