I like to masturbate with my aunt's silk clothing, especially those that are worn.
I would get a couple of pillows and arrange them such that there is a slit in between for my cock. I get one of her used silk slips and 'wear' it on the pillows. I get another of her silk skirts (I also prefer a used one so that I could cum on it and throw it into the laundary again) and 'wear' it on the bottom of the pillow over the slit. By the time I've done this, my cock is already fully erect, and I would insert my cock between the silt and pump away. Feeling the smooth sensation of the silk skirt against my cock was the greatest. I would smell and lick her slip and I pump away. It smells wonderful, a bit of odour and perfume. It won't be long before I cum, even though I try hard to resist.
There was a few times that I had accidently cum on her clean silk skirts instead of stopping and putting on a condom. I would cum again and again with this technique, it's hard to resist ejectulation! Every time I see my aunt's silk clothing, I would feel so horny.
