Two people in close vicinity to one another touching their own groin areas in order to obtain sexual pleasure. Two women touching each other's genitals is called SEX. Two women curled up together on the bed touching their own genitals is MUTUAL MASTURBATION.
I lay on my side, her fingers twining the hair at the back of my neck, my right hand rubbing my clit hard, her left hand between her own thighs, her breath exploding against my forehead, damn this mutual masturbation thing is great!
