Zossie has just penetrated her vagina when a soft and lullaby version of Twinkle Twinkle Little Star began to play. She groaned upon realizing the playlist for her babysitting job was still on play. She babysat a local girl three doors down named Sophie who was just over a year old. Her mom had finished maternity leave recently and Zossie had been watching the child after school let out for several weeks now. She was about to grab her phone and change the music when her eyes drooped sleepily and her hand fell limp beside her as the lullaby rang through her ears. She thrust that dildo in and out of her vagina several times over and each thrust seemed to decrease her age. First her braces reappeared, then her breasts and hips deflated to pre-puberty levels. Acne vanished entirely and she began to shrink as she lost defining feminine features. Her hair became brighter and softer and sexual drive vanished entirely. She tugged the dildo from her pussy and lay there aged around eight years old. She was in a daze still and her hands automatically brought the dildo to her lips. She began to suck on the plastic cock and each suck made the hard plastic softer. It shrunk and shrunk as a small handle formed and soon the entire thing was a dick shaped pacifier. Zossie sucked on the pacifier as the dick shape faded away leaving her with a regular soother. Her body then began to shrink again. Her braces vanished, her limbs got skinner, and she regressed down past five years old, then four, then three, then two, and finally one year of age. She closed her eyes as her headphones slipped out of her ears and her phone morphed into a baby monitor. She was now just over a year old, exactly a month older than Sophie was and her bed morphed into a crib to adapt to her new reality. Her room changed so it was barren and cleaned out, ready for a new person to put their stamp on. She sucked on her soother happily as memories of Zossie altered and she vanished from a lot of photos, now she was a late life pregnancy that had come as a shock to her forty four year old mother. She slept peacefully in her room and a diaper and Onesie formed around her body as reality set in and her mind regressed to that of a one year old who spent her days around Sophie and some random teenage girl who watched them named Brooke, Brooke had graduated high school and was earning money for university by babysitting several children and now Zossie and Sophie were registered in that program. Zossie sniffled in her sleep and sucked on her soother some more, completely unaware that just minutes earlier she had been on the cusp of womanhood.
