I haven't seen this technique posted anywhere, so I thought I'd post it here. This technique is especially good if you put the magnifying side of a make-up mirror between your legs so you can watch.
First, begin by masturbating the way you normally would but only enough to get yourself wet. Then take a Q-tip and dip one end of it into your juices. Using the moistened Q-tip, get to work on yourself.
Try stroking the entire length of your shaft, either back and forth or in one direction. Pay attention to how it feels as the Q-tip moves over the swell of your erect clitoral head underneath the hood. Stroke up and down the furrows between your inner and outer lips. Stroke the inner surface of your inner lips. Make tapping notions. Make circles. Make zig-zags. Flick back and forth across the shaft. Try stroking different areas and using different strokes and levels of pressure. You might want to stay away from the exposed head of the clitoris if it is very sensitive like mine is, but circling it feels good. Remember to keep the Q-tip moist by dipping it into your juices from time to time. Tickling the opening of the cunt both feels good and keeps the Q-tip moist.
You can do this as long as you like, and when you are ready, put the Q-tip down and finish yourself up in your usual way.
