Plastic Panties

I discovered masturbation by humping things, having dry orgasms rubbing against the mattress, pillow, floor. I spied on girls panties too if they showed them, often hump the floor as I peeked if I wasn't seen.

I knew this girl that showed her panties a lot, but one time she was wearing these white plastic panties. Not sure if she had regular panties under them, but they looked hot, like they felt so smooth. I later saw some at a dime store and bought them like they were for a little brother that wet his bed a lot. I got home and had already been humping my mattress, pillow or floor while wearing my sister's big granny panties. I was still dry cumming at the time.

I tried on the plastic panties, climbed on my pillow humping it slow, needless to say I came really hard, this time with a little sperm. I started this after school alot, always being alone for a few hours till everyone else got home later. I would get boners thinking of putting on the plastic panties and humping. I started shooting big loads of sperm doing it, no hands, just rub up and down on stuff till I'd cum. I tried lotion in them too, oh my God that was even better and still no cum or mess on whatever I humped. I learned to edge in them as well, and wore them to bed every night to hump in. I still do it in plastic panties every chance I get.
Hope others try it and enjoy.
