First you get yourself nice and wet, like soaking, then take the hand that you write with, and take the two fingers closest to your thumb (your pointer/index finger and your middle finger) and make them wet with your mouth or your pussy juice (you should be glistening wet for this to work properly). MAKE SURE YOUR NAILS ARE TRIMMED AND NOT SHARP.
Slide those two fingers in, with the fingerprint part of the fingers facing up to the roof (nails down), slide them in firmly but slowly, as far as they will go without using too much pressure. If you are really tight you may need to start with one, and if there is a lot of wetness but resistance, you may need to tease your pussy some more. Once you get those fingers in, tease your inner walls slowly with the pads of your fingers, and get yourself even more juicy. When you think that you are ready to have the orgasm of you life, begin:
Now you will maneuver your fingers to find your g-spot. Yes, it exists, and yes, every woman has one. Slide your fingers in about 2 inches, UP, and then BACK towards the front of the pussy (like you're going up behind your clit). The g-spot is actually a patch of the inner walls which is on the FRONT INNER WALL of her pussy, above the hole itself. So, in, up, and back towards the entrance. You should feel, on that wall, a very rough patch of skin - rougher than the rest of your smooth inner pussy. You've found it. Congratulations.
By making a beckoning motion with your two fingers (or the come hither manuver my girlfreind likes to call it, aka a bending fingers motion), you should be able to pull the fingerprint/pad part of the tips of your two fingers against that spot. Try it. Pull back against it with your two fingers and press a little. Tease it, stimulate it with your fingers. Make youreslf feel good. You should be squirming and breathing very heavily by now.
As you start to rhythmically tap/press/pull your fingertips against the g-spot, you should start getting wetter. If you're doing it right, you'll start to hear squelching, sponge-like sounds. The g-spot is like a sponge, it contains a lot of liquid, and feels rough. Keep pressing your fingers against it, over and over, rhythmically, with the same kind of rhythm as if you were sliding a dildo, a cock or like object.
As you get wetter, start doing it harder. Then your body thrashes from side to side, the harder you do it. Eventually, you can replace the tapping/poking of the g-spot with an outright speed-sliding of those two fingers in and out of your hole. Do it faster and faster, maintain the rhythm, but increase the force. Even when you're slamming them straight in and out of your hole, try and maintain an upward, outward force with the fingertips, so you're still pressing up against that g-spot even as you're slamming yourslef with your fingers with reckless abandon.
Through all of this, you should be squelching, squirming and OBVIOUSLY loving it. If it hurts (especially if more than once, you might want to stop or at LEAST slow down or not do it so hard. Make sure your always wet - not dry for any period of time, it will not work then)
Now here's the crucial part. When you get close to ejaculation, you will feel the need to pee. this is just a temporary sensation that will pass and you have to make sure you do not stop and you do not desist in your slamming. Keep your legs apart and you KEEP GOING, but make sure you stay relatively still (or you might hurt yourself on your fingers)In fact, when you need to pee, that's when you should start doing it harder, cause orgasm is around the corner.
10-50 seconds after the pee sensation begins, you will start to cum. When you do, DON'T STOP. Just do it harder and harder and harder, pressuring the g-spot upwards all the while. Now you should start to ejaculate, when you do take your fingers out but keep rubbing your clit, If done right I gurantee you will scream, and your pussy will start shooting clear (transparent), odorless liquid all over the place. There could be a lot of it, it might soak everything around you, so make sure you're prepared.
I guarantee you, if you never had one before, the squirting orgasm will be the best orgasm of your life. If you want to ejaculate in great volumes, drink lots of water before you do it, and stay well hydrated. Once your finished squirting, YOU CAN SQUIRT AGAIN. Especially if you didn't do it too hard, and still got yourself to cum, you can usually start all over, and between one and ten minutes later, you'll be squirting again. Usually, you have to do it harder each time. My record is seven. 45 minutes later I passed out for 6 hours afterwards (it's physically exhausting and dehydrating) so be careful if you try more than 2 at one time.
So happy super jilling and it does take practice.
