Story Text:


"I was supposed to be Queen!!" Cassandra screamed out in absolute rage; she was the firstborn, for crying out loud. Cassandra had always been in the lead as the favorite to become Queen. Her blood boiled as she stood before her younger sister, Charlotte, who clinched the crown at the last moment.


The punishment for failure was steep. Any princess who failed to secure the crown was demoted to being a mere court doll, a mindless slave who would do anything commanded of them. Cassandra had already been stripped of her lush, intricate clothing, which would no longer be needed. Her petite body had been forcibly changed into clothes that were far too large. Clothes fitting a court doll. 


"On your knees before the Queen!" One of the guards forced Cassandra to the floor, gripping her wrist tightly behind her back. The top of Cassandra's outfit slid down, nearly exposing her small breasts. She resisted the guard but could not fight against his overwhelming strength. Her pride had been stripped away, leaving her humiliated as she looked up at her young sister with pure, unfettered rage.


"This is your punishment for underestimating me." Charlotte felt an extreme sense of satisfaction seeing her perfect older sister forced down on her knees, bowing before her. She placed the black tiara on Cassandra's head. It would curse anyone who wore it, turning them into pristine dolls. Cassandra's howls of anger quickly morphed into agony as her body started to change. Heavy cracking sounds echoed as Cassandra's joints snapped and reshaped to ball joints. Her milky skin texture began to switch to a more smooth and vinyl-like surface. 


"No! No!" Cassandra screamed, whipping her head but failing to knock off the tiara. Even if she had freed herself, it was far too late; once the transformation started, nothing could stop it. Her sharp violet eyes began to soften and grow cloudy. Cassandra gasped for breath as her chest tightened, her ribs cracking and reshaping into a more doll-like figure. Her smaller breasts expanded, becoming larger and firmer by the second. Simultaneously, her hips, ass, and thighs widened and adequately filled out her previously oversized clothing.


Cassandra's cries of agony and rage subsided, becoming dull whimpers. She'd been transformed into something unrecognizable. The fiery passion that burned within her eyes had become muted. 


Once the doll had gone entirely silent, she was lifted to stand before the Queen. "It is my humble honor to serve you." The doll's head tilted slightly as she spoke in a monotone voice. 


 Internally, Cassandra screamed. 'I can't control myself-- I can't say what I want!' Despite her overwhelming panic, a glassy, serene smile remained plastered across her face.


Charlotte sat back on the throne, observing her newest toy with a twisted smirk. 'It's good to be Queen.'
