Well, actually, that's not quite how female ejaculation works.Every woman has a g-spot (also known as the urethral sponge). When stimulated, the tissue of the urethral sponge fills with blood, becomes engorged, and swells. The paraurethral glands surrounding the sponge fill with fluid and also swell. No one is sure why some women ejaculate often, some women do it occasionally, and some women never do. The majority of women achieve it through direct g-spot stimulation, but some can squirt via clitoral stimulation or anal penetration alone. When a woman is very aroused, (and especially when firm pressure is applied to her urethral sponge) the glands release the fluid through the urethra, and she ejaculates. The fluid is similar to fluid produced by a man’s prostate (it's usually clear and has no taste or smell like urine does).
Oh, as for recommendations, any of the Seymore Butts movies with Alisha Klass are fabulous, and there is even one called Guide to Female Ejaculation, or something similar.
