Isabella Strand was proud of her nine-year-old daughter Eleanor, who went by Nora. She'd got into a unique piano program at the nearby University of Westminster, sponsored by Transport for London. The girl had good friends in Becky, Clara, and Ana, and was quite outgoing. The last couple of months, though, Isabella had gotten just a bit worried, as all three of those girls were now enslaved as pianists at three stations on the Bakerloo line. She knew her daughter was at risk of joining them, as Nora couldn't pass up a free piano to play.
It didn't help that Nora always wanted to visit her friends in their new alcoves. Seeing those girls, once normal little girls in their school uniforms running around the neighborhood, chained to their piano benches naked playing song after song made her nervous that it would happen to her daughter. The fact that Becky was, and Clara just starting to, show her pregnancy just made Isabella more scared for her daughter. However, she couldn't stop from traveling the Underground, and Nora wouldn't stop playing.
One day mother and daughter entered Embankment Station, intending to take the Bakerloo Line home to Kenton, and Nora got ahead of her by some distance. Only the girl's orange jacket enabled Isabella to spot her through the crowd and even then the press of exiting passengers blocked her view. Suddenly Isabella heard Scarlatti's Sonata in F sharp minor playing from a piano up ahead. Her daughter had found a piano in the tube station. Suddenly Isabella felt a chill as she heard the sound of a gate closing. She rushed to discover Nora seated at the piano, locked behind the gate. Nora wouldn't stop playing.
A chain suddenly dropped from the ceiling and grazed Nora's neck before sticking to her gold chain necklace. Isabella knew her daughter was being enslaved by the station now. She pounded against the gate, trying to get her daughter's attention, trying to get her daughter to move before the chain solidified it's attachment around her neck. Nora wouldn't stop playing.
Isabella saw the young station master and called out for help. The young man came over with his keys already out, just as Nora's orange jacket slid to the floor, revealing her floral vest and white blouse. Isabella heard her daughter's shoes hit the base of her piano and watched them roll out from the bench. She called for her daughter to stop, to get away. Nora wouldn't stop playing.
The keys didn't work, and now Nora's gray skirt fell loose revealing her yellow panties to the station. Balled up socks rolled out from under the bench as Isabella frantically jerked the door, not believing that it was still fixed in place. She demanded that the station master get her daughter out, but he just smiled. Nora wouldn't stop playing.
Then Isabella noticed that her daughter's vest and blouse were sliding down to the floor. Nora was now in just her panties, as her mother noticed that her daughter's ankles were now chained to the piano bench. Isabella turned to the station master, begging and pleading with him, but he just smiled. Nora wouldn't stop playing.
Out of the corner of her eyes, Isabella spotted two new chains lowering, dangling above her daughter's wrists as she played. She turned back towards her daughter, just as Nora's panties fell off her body, leaving her naked. She pleaded for her daughter, but the station master just dragged her away. Nora wouldn't stop playing.
Isabella wasn't sure how she got home that night, but the next morning she and her husband headed to Embankment. Much calmer than the day before, the two discussed with the station master what had happened to their daughter. TfL had exercised their clause in the contract they'd signed when Nora started her piano lessons. As their daughter finished her breakfast, Isabella examined her naked daughter. There was now a TfL roundel on her left shoulder, and Isabella parted her hair in the back to discover a fresh cut just at the base of her skull. Nora seemed perfectly normal other than her nudity as she ate, talking about what she had played the day before, unconcerned about the cuffs and chains she was wearing.
Isabella watched as her daughter was taken back to her piano and chained by the station master there. She promised herself that she'd try to be with her daughter as much as possible, as the sounds of the piano filled the station once again. Still, she had to get to work, so she cried out her goodbye. Nora wouldn't stop playing.
The next morning, Isabella arrived to see her daughter leaking the station master's seed. The roundel now was colored the brown of the line instead of just the outline it had been the day before. They ate breakfast together. She washed her daughter with a sponge bath before the station master took Nora to her piano and locked her to it. She returned in the evening to share a late dinner with her daughter. Once it was over, Nora wouldn't stop playing.
Days turned into weeks, and weeks into months. A routine developed. Isabella would arrive to have breakfast with her daughter, and then a late dinner that evening. For an hour in the off peak, she would be allowed to walk with her chained daughter around the station. Then after one last session, the station master would take her to bed and Isabella would take the last train out of the station. Nora got morning sickness, and her belly began to swell with the station master's baby, but nothing changed. She didn't even grow a single millimeter in height. Nora wouldn't stop playing.
One evening, as Isabella was walking with her daughter through the station, Nora went into labor. The station master quickly unlocked Nora, and together they headed home to Kenton as the labor progressed. Nora gave birth as soon as she got home to a baby girl. Still naked and cuffed, a week later Nora returned to her station to resume her routine. Isabella tried to keep up her routine while taking care of her daughter's child, and later children, though it was much harder to do so, and regular visits tailed off. Nora didn't mind. Nora wouldn't stop playing.
