This is something that I have been blessed to experience many times. Almost anyone can acheive it. So far most of my friends that I've told how have beeen able to do it if they were female or help someone if they were male. I can explain from both vantage points cause Ive also had the privilage of being soaked a few times.
The biggest thing you have to remember if your a woman and if your a man wanting to help the woman your with acheiv this is that when it starts to happen you feel like you have to pee. If you flex your K muscle at this moment you will still have an orgasm but you won't squirt so you have to try to stay totally relaxed.
If you really want to go for it I suggest you buy a g-spot vibrator.. it can take quite a while of stimulation for it to finally occur and this is not tthe time for tired fingers. The Adam and Eve catalog has an awesome one .. its about 7 inches long and looks like big capsul on the end of a bent stick, not to mention it only comes in bright purple so if you get the catalog its pretty hard to miss.

the link that was givin earlier is a great starting point, but like everything sexual, what works for one doesn't always work for the many.

The only other advice I can think to give you is

#1 work on stamina if you are giong to be the giver.. this is not something you can go oops toungue cramp let me switch to my finger... If you stop you have to start all over with this.

#2 Lots of Lube.. it takes a while and if you aren't using oral for the clit it can get uncomfortably dry.

#3 have a towel near bye... a female ejaculation makes a mans ejaculation look like a leaky faucet compared to a busted pipe,

and last but not least
#4 if it does happen whatever you do don't act weird afterward if you wre the giver.. she needs to know that it was a turn on and natural.. its easy to feel like a porn freak if you don't reinforse this.

I hope this help someone and please forgive the spelling.
