I was reading the techniques on this site - which is the best! - and I came across one that suggested using pearls to rub up and down your crack.
Well, I don't have any pearls so I found these heavy Indian beads. They have sharp bits and my masturbation feels too smooth without them. For those who like the roughness I would definitely reccomend them!
I like to lay them in a line running from my butt to my clit, tightly pressed in between my lips and massage my clit in between each side of the beads. It's a gorgeous sensation, and the sharp bits really add to the climax!
I'm off to do it now! Bye, happy wanking people :)
