Blonde stepsisters indulge in a taboo game of contortion and doll play, stretching their lithe bodies into impossible positions. One sister, shaved and skinny, takes the lead, inserting a massive dildo into her tight, flexible form, mimicking the real doll they've brought home. The other sister watches, envious of her sibling's flexibility, as she's forced to remain passive, her arms and legs bound like a real doll's.
