Does anyone remember the almost clear but colored thin plastic or PVC jackets popular in the early 80's? My older sister had one and I looked at it one day and got so turned on by it that I just had to 'steal' it from her.
When my parents were away one day I put the jacket on with no other clothes on and it felt so erotic that I took it off and wrapped it around my then skinny lower abdomen and groin/genitals. I got so hot and turned on by the jacket that I immediately started to jack off in it by rubbing myself into orgasm. This was when my long standing plastic fetish started.
When the jacket was all torn up I started using smooth plastic grocery bags. I was small enough then that I could cut holes in the bags and make panties and even a 'bra' or 'tanktop'. As time went on I woud find a piece of rope or an old thick shoestring around the house and tie it tight around my waist, with the plastic 'panties' pulled up tight under the string and the plastic 'top' pulled tight under the string. Then I would rub myself hard on my dick and my balls and simulate being fucked or raped. That was when my plastic fetish really took off!
