Research suggests that the female ejaculation comes from the Skene's gland, which is located along the urethal sponge.
I would use every trick in the book, woman have so many pleasure points such as the clit, outer vaginal lips, inner vaginal lips, the area just underneath the uretha is very sensitive aswell and nice to GENTLY lick ... the G-spot as we all know but also the A-spot ''Cul de sac', U-Spot which is the Skene's gland and easy to locate and hit .. its this which I THINK got some of my girls to shoot. You've also got the Rectouterine pouch and if your long enough, some woman apparently like the uterus touching and can get a uterus orgasm from it and literally piss everywhere.
So LOTS of thngs to try and play with, and thats not incl the external areas like breasts, neck, inner legs etc etc.
