If your girl isn't a "natural squirter" its all about hitting her spot, and lots of foreplay, her being completely comfortable is above key. If she never squirted before she might not be comfortable with gushing every where since it might feel similar to having to pee before she bust. So she needs to know its all good.
But don't be scared to introduce toy's into the bedroom either, I had one ex that not only needed a curve to touch her Gspot, but speed as well to squirt. So unless you just was built with a curve to the left or right and X amount of inches and could move at 10 miles per hour for 3-5 mins at a time you wasn't getting the water works for the most part.
By the time you all are about to have sex she needs to be so emotionally invested that she can't help but bust. Just get to know her body and her mental, does she need that kink to squirt or love making.... Good luck breh.
edit:
One of the best way to find a chicks spot is to finger her, rub the walls when you find her spot you'll know, from there on out its all up to you. PSA (please dont finger you girl with nails that are longer than your fingers)
