Soft nylon tricot does it for me, ever since childhood I have been fascinated and aroused by pretty feminine clothing. My teachers displayed their gorgeous petticoats and dresses. After school going through my mothers things fondling and trying on her silky petticoats and later nighties and occasionally dresses. Getting so carried away with the silkiness and just wanting to have wild unprotected sex with them, but always having to stop and withdrawn just prior to orgasm. Oh how I wanted to just keep rubbing my swollen knob thru the layers of beautiful nylon whilst I convulsed and ejaculated. That's what I do regularly do now and I love it.
