I like to do this when no one is home. I take off my pants and sit on the edge of the chair. I get a good fantasy going, like sucking the cock of my lover, him sucking my tits, and then I slide my hand between my legs.
I use the index finger of both hands to squeeze the hood of my clit, rubbing my fingers back and forth in opposing directions. So while I'm rubbing forward with my left finger, I rub backwards with my right. This gives my clit a tingling and burning sensation that's so good. It's so much better than just rubbing in circles. If I start getting too close to coming, I move a hand up to play with my nipples, pinching and tugging them. Then I can move my hand back down again.
My sensitive clit loves the pressure and stimulation. When I start getting close to orgasm, I pinch the hood of my clit and thrust my other fingers into my pussy, then I feel the warmth of that rocking orgasm spread through me. Try it, it is wonderful! Tell me it isn't the best orgasm you ever had.
