Jeffery Hammermill was the youngest of the Bakerloo line station masters, as well as the newest at just twenty-six. Today he was examining the piano installation, in preparation for a permanent occupant. The piano was in tune, of course. It was actually brand new, a Yamaha upright, placed inside the alcove. The cage locks were solid, and ready for automatic operation. The laser had been installed and tested. The special chains had been installed and were ready to capture the appropriate girl.
Jeffery had visited the two captured girls up the line, Becky at Oxford Circus, and Clara at Piccadilly Circus. Of the two naked girls, Becky was already starting to show what her station master, Bill, had done to her. The girl's belly was already starting to swell a bit with Bill's baby. There had been quite a crowd around the naked girl's playing piano, including one girl who actually sat down and did a four hands piece with both Becky and Clara the day before.
It was that girl, Diana Thomas, age ten, who apparently went by Ana, that Jeffery planned to install in his station. Ana was entering his station right now, having been directed past her friends and intending to get off at his station and head back up the Bakerloo to see her friends. Jeffery wasn't going to let her. Instead of taking the cross platform connection between platforms three and four, Ana took the two escalators up to the ticket hall. She wore the usual outfit for a girl her age: winter jacket, skirt, knee high stockings, and saddle shoes.
Jeffery watched as Ana spotted the piano and rushed over to take a seat at it and started to play. He quickly hit the button to start the process, looking up just in time to see the gate swing shut and magnetically lock. None of the keys would do anything to open it now, which was important.
The dangling chain caught Ana's necklace, just as her mother entered the station, one train behind her daughter, as she'd got off at Oxford Circus and then realized that her daughter had not. Jeffery watched as the mother tried to open the gate and found it firmly locked, and her daughter not responding to her requests. Ana played on.
Jeffery's displays informed him that the stripping procedure had started, with the cuts started on Ana's bright orange winter coat. He wouldn't be able to continue to watch his displays, as her mother rushed over to him to get some help. Jeffery picked up his keys and headed to the piano alcove, arriving just in time for Ana's coat to fall off, revealing her blue vest and silver blouse. Jeffery fumbled with the keys as he tried to reassure Ana's mom. Ana played on.
Jeffery noticed that the lower chains were working on removing Ana's stockings, her shoes already laying to the side. He could see that the cuff had solidified around Ana's neck already, so even if the key that he was inserting were to work, it wouldn't be enough to let her go. As he demonstrated that the key was not working, even letting Ana's mother try, the cuts were finished and Ana's gray skirt fell free of her body, revealing her blue panties. Her mother cried out. Ana played on.
Jeffery noticed that the cuffs were now solid around Ana's ankles, locking them to the piano bench. Her mother was getting hysterical, as Ana's vest and blouse fell open and off her body. She was wearing a training bra, and the only thing else Ana now wore was her panties. The woman braced her feet against the frame of the gate and tried to pull the magnetically locked door open. Ana played on.
Jeffery noticed that two new chains were working their way around Ana's wrists. Mrs. Thomas noticed that her daughter's bra and panties had slid off, the bra now laying on the floor. Mrs. Thomas fainted as her daughter became naked. Jeffery carried the woman to his office. Ana played on.
From his office, Jeffery watched the wrist cuffs become solid. Ana was now fully chained. When Mrs. Thomas woke up, he explained that her daughter was now the responsibility of TfL. She'd be paid with the money deposited in her family's bank. TfL would keep the girl healthy and fed, but it was unlikely that the girl would grow up. Of course, Ana would be having babies, and she's return home to have them. Mrs. Thomas could come and watch her daughter play at any time, but there would be no more hysterics in the concourse. Then Jeffery sent Mrs. Thomas home to Kenton. Through it all, Ana played on.
Jeffery served Ana lunch and dinner, and at the end of the day he moved her to a cot and locked her head in the last bit of hardware. It would end her physical growth. Only her hair and belly would grow now. It would also make her fully compliant to Jeffery's orders, and increase her repertoire of pieces to play. Jeffery had chosen to make sure Ana knew all the dramatic pieces to call attention to herself.
In the morning, after breakfast, he locked Ana back to the piano bench, this time with the lower connections for her wrists, instead of the upper ones that had ensnared her. He'd just closed the gate when Ana's parents arrived to see the naked girl play. They stayed all day, and Jeffery let them have lunch with their daughter, before she went back to her piano to play on.
That evening, Jeffery began the pleasures of being a station master with a chained young pianist. He locked her ankles and wrists to above her head, and slid his hard cock into the virgin girl. He didn't last the first time, but the second time he lasted longer, and he woke her the next morning with a long hard breeding. Then he unlocked her ankles and wrists, fed her breakfast, and locked her to her piano. Ana played on.
Days turned into weeks, and weeks into months. Jeffery bred his little pianist nightly, and it wasn't long before she was suffering from morning sickness. As her belly began to swell, Jeffery was proud of Ana and what she'd help make the station. Many of the off-peak regulars saw the girl waddling through her exercise route, chain dangling from the ceiling, and requested their favorites be played on her return to her piano. Ana played on.
All too soon, Ana reached the end of her first pregnancy, and was sent home to Kenton to give birth. Jeffery missed the pianist, and so did the regulars. He was sure to pick her up when the week was over and chain her back to the station. He didn't let her have another period, as her night time and morning breeding were part of her life now, her belly swelling with his child again and again. Ana played on.
