Rebecca "Becky" Wyvern was ten years old when she entered Oxford Circus Station, intending on getting on the Central line with her mother. They were early, and the girl spotted the piano in an out of the way alcove in the ticket hall. The girl rushed over to the piano, her long brown hair trailing behind her. She brushed the dust off the piano bench, and slid it back out, at least as far as the chains keeping it there allowed.
There more chains attached to the wall than were required to restrain the bench, but Becky ignored that. Instead she sat down, pushing her gray skirt against her behind, and unzipping her black and gold winter jacket to free up her movement. Then she started to play.
As she played, things started to change. First, behind her, a barred gate slid shut behind her, preventing her mother from reaching her. Then the first chain dropped down to touch the back of her neck, linking with the sliver chain that she wore around her neck. The chain tightened, until it became a silver choker of a cuff around her neck. Becky was now chained to the alcove, as she played on.
Now her winter coat fell off her, revealing her red Christmas vest and white blouse. Then her gray skirt fell open on the bench, revealing the pair of pink panties that she'd worn. Her nice saddle shoes were pushed off as she played, leaving her in her white stocking feet. Her mother cried out for help, but Becky played on.
Chains slid around Becky's ankles, rolling the socks down off her feet before fastening themselves around her ankles and cuffing her feet to the alcove. Then her vest and blouse opened up, and fell off her body. She was now down to just her pink panties. The station master told her mother that he couldn't get Becky out, and Becky played on.
Chains now reached to connect to her two bracelets. Two cuts appeared on each the side of her panties, and they fell free of her body. The chains continued, finding her wrists, and surrounding them. Cuffs formed, and now Becky was chained to the alcove with five chains. Her mother had to leave, heading home to Kenton, but Becky played on.
The station master removed Becky's laser cut clothes from the alcove the girl was chained in. He provided her with food for lunch and dinner. The gate was always locked back behind her, and the chains kept her on the bench. She was naked and afraid, but Becky played on.
When the station's last train left, the station master came and unlocked Becky from her alcove. She was locked in a small closet with a cot in it, her head tightly held, and allowed to sleep. As she slept, the chains went deeply into her mind, removing parts. In the morning, she was returned to the piano and her alcove after breakfast. Her mother and father found her there, chained to the alcove again, but no longer behind a barricade. They begged and pleaded for her release, but no longer afraid, Becky played on.
On Becky's second night at the station, the station master chained her up differently on her cot, locking her wrists and ankles to the top of the cot. Then he took her virginity, and bred her again in the morning before giving her breakfast and locking her back in her alcove. Her mother noticed the change, and pleaded with the station master to stop and let her daughter go, but Becky played on.
Days turned into weeks, and weeks into months, as Becky's mother pleaded for her daughter's release. Becky suffered from morning sickness. Her belly started to swell with the station master's baby. She was not unlocked, and her chains kept her in the station as she was allowed to waddle for exercise in the station on a long chain in the off-peak evening hours after her mother left. But while her mother was there, she stayed in her alcove and played on.
Finally, one day Becky could not play. Her labor hit, as she left her alcove. The station master let her take the Central line home to Kenton. Her cuffs remained around her neck, wrists, and ankles as she reached the home she'd left nine months before and her water broke. Her mother wanted to keep her, and the baby that had been born in that home, and not return her to the station master. It was not to be, for Becky returned to the station just a week after she gave birth, and locked in her alcove, she played on.
Becky never had a period, nor did she grow a millimeter taller. The only things that grew were her hair and the latest baby in her womb. The peeled pregnant pianist was a fixture of the station. Over and over she had the station master's babies. Her mother always wanted her to come home, and she did, every time she went into labor, but she was chained to the station, and Becky played on.
