Ive found that when I play with girls and get them really turned on, horny and wet and deny them the chance to cum or orgasm by playing with them and then stopping just before they are about to cum, let them cool off a bit and then do that again several times, bringing them really close to an orgasm and then not let them cum, normal girls who dont usually squirt or gush end up gushing when they finally do cum. Yes I know its cruel but I do love orgasm denial and plus making girls squirt!=)
