I love to do it with a hand mirror propped between my legs, so I can see how close my fingers are to touching where I want it most. I prefer the natural approach. I sit on my bed with a lamp above me so can see what I'm doing very clearly. Then I put my feet together and push my knees down as far as I can, so that my pussy is spread without my having to touch it. I lean the mirror on my feet - it's the sort of mirror that has two glasses, one on each half of the compact. One of the mirrors magnifies, which I like.
First I just spread the lips a little further and watch myself getting wet. It doesn't take a lot to get me there because just looking is kind of sexy, but sometimes I run through a fantasy in my head to help myself along. I won't touch myself until I'm soaking and I can see the moisture shining in the light from my bedside lamp. The waiting is such a turn on.. I'm dying to touch but I always manage to keep control of my hands. I can almost see my pussy swelling a little in delightful anticipation.
Then, very gently, hardly touching (when I first touch myself I'm really sensitive), I stroke my middle finger from the bottom of the lips slowly upward until it's right beneath my clit.. I can see the tip of my finger hovering beneath that fantastic little spot and my pussy's tingling from where I've touched it.. and then I go back to the start and do it again, bottom to top, always stopping just beneath my clit an pausing to look, as many times as I can bear. Occasionally I might slip my fingertip into my pussy and then return to the bottom of the lips and start over.
Then the next time I just briefly brush my clit with my fingertip before starting my stroke again. It's such a slight touch that I can hardly feel it where I've actually made contact, but it makes me shudder and seeing it is amazing, that teasing little caress. When I've done that one a few times, I gently stretch the skin above my clit so it's exposed, and tease myself again for several strokes, bottom to top, slipping two or three fingers into my pussy now and again, watching my finger come a hair's breadth from my aching clit but not quite touching..
At this point I'm so close to coming that it only takes a few seconds of direct stroking on my clit, watching all the time of course, to bring myself to a really intense orgasm. If anyone has any suggestions about how to make the mirror more secure, I would be grateful, as I can't keep my feet still when I'm coming, so I always miss the crucial moment.
For some reason it's so much better if I'm wearing coloured nail polish.
