In a clinic converted for their fetish, the doctor dominates two lesbian slaves in an everything-butt anal extravaganza. She gapes their asses with her skilled fingers, then uses a variety of toys - dildos, buttplugs, and strapons - to fill and stretch their holes. The slaves eagerly lick each other's pussies and asses, their excitement escalating as the doctor intensifies their anal play, leaving them panting and asses glistening with lube and juices.
