I'm a little unsure which way is best. I've worn a knee high stocking over my cock and balls and then put on a pair of pantyhose over the top so it was slippery in my hose, then put on stockings on my legs over that.. I could rub my legs together as I slid all over the bed and let the double layers of silk stroke my cock till I came. Messy on the hose and sheets.

Anotherway is a very slicked up vibrator working the back end while wearing a torn crotch pair of pantyhose and using a knee high on the cock and stroking hand to shoot a massive load. Note it helps to squat on the vibator more than laying on your back.. Better control and more erotic if you ask me.
