She knows what she likes and she liked that. She should try a Hitachi Magic Wand for sheer intensity and try moving it around the groin in a circular motion before resting it on the clitoris or clitoral hood. If she is tied down or restrained her lover could do it for her to increase the eroticism and pleasure, assuming she wants to be completely dominated by a masterful male. Either way it gets the female juices flowing in a tsunami of pussy juice with each orgasm and there can be multiple of them. I have had several Hitachi Wands and small toys over the years. My Colombian mistress cannot get enough of them so I bought her one for private use when I am not around and it gets a lot of use.
