It's called tribadism
Quote:
Tribadism or tribbing also known by the slang term scissoring is a form of mutual masturbation in which a woman rubs her vulva against her partner's body for sexual stimulation.[1][2] The term is most often used in the context of lesbian sex, but is not exclusive to lesbians. Tribadism can also refer to a masturbation technique in which a woman rubs her vulva against an inanimate object such as a bolster, in an effort to achieve orgasm.
