Every woman should have a small silver vibrator cleverly named The Silver Bullet. I love mine! Almost every time I masturbate, I use it.
I start off by watching some girl on girl porn (girl on guy just isnt very interesting to watch when you do it all the time) until I get a little wet. Then I tease myself a little bit on the lowest speed still wearing my panties. Once I want more I turn over on my stomach with my legs close together so I can place the Bullet on my clit without it vibrating away. After this point, I have the speed all the way and my back is arched so my clit is getting all the stimulation possible. Soon I am having the most explosive orgasm that I have to stifle my moans into my pillow. My boyfriend can't even make me moan that loud!
Another way I love to get off is by using the bathtub. Lie underneath the faucet with your legs up in the air and turn the water on. Lie back and enjoy as the flow of water massages your clit. I have great orgasms using this technique too.
