Room for a third woman
Lesbian threesome sex puts three women in one bed, enough for one of them to be kissed, licked and touched by two partners at the same moment. FFF is the shorthand for it: three women, no man.
Shapes a trio falls into
Two on one is the simplest shape, with one woman lying between the others, a mouth on her tits and another between her legs. In a daisy chain each woman licks the next, so three pussies and three tongues close a triangle. Two women side by side on their backs, legs open, turn the third into the one who serves both. A couple who invite a guest make the newcomer the focus, and a mixed-age trio puts an older woman in charge of two younger women, all three 18 or older.
Three roles instead of two
A pair in lesbian pussy licking splits into giver and receiver; the women in a lesbian threesome add one more role, the one who kisses, watches or waits her turn. Its defining feature is that odd number, which leaves two women on one at any moment and lets the pairing change with a turn of the body.
