In a steamy, kink-filled session, two yoga-practicing lesbians indulge in their shared fetishes. One, a slave to the other's bdsm whims, is made to kneel and service her mistress's ass, rimming and licking until her mistress is dripping with wetness. Then, a strapon is introduced, and the slave is fisted, her ass gaping wide as she's forced to take everything her mistress gives.
