Mary brought the heavy box inside in confusion. She certainly hadn't ordered anything like this, and the lack of any shipping labels or other identifying marks meant somebody had quite literally dropped it on her door step and left.
She set it down on her kitchen table and read the note again, trying to make sense of it. Vials? Transform? People and animals? This had to be a joke, or some viral marketing stunt, or something equally normal.
She had always been a curious person, though, and with a smirk she reminded herself magic wasn't real as she hit the gold adorned button on top of the chest.
The chest clicked and whirred, and instantly it flung itself open. The sides parted to reveal spinning racks of glass vials housed in either half. In amazement, Mary spun one of them and saw hundreds if not thousands of pictures of different people, sizes, shapes, and species. Her eyes widened as she realized she never saw the same vials come back around twice, and to her disbelief she realized that each time she spun one of the racks around, she had all new selections. She tried it with the other side and her brain experienced intense shock as she realized that the same thing was happening. It was impossible, but this single box held maybe thousands of vials in an impossible space.
Still in shock, she put a finger to her mouth trying to comprehend the glitch in the matrix she was seeing with her own eyes, and finally she stopped playing with the racks and pulled one vial out to inspect it. "Shrinking" the vial read, with a picture of a man and an arrow drawn to a smaller man.
Mary eyed it suspiciously, popped the rubber stopper out, and sniffed it. It seemed to be without a distinct aroma. The tall blonde took a tiny sip, swallowed, and stared at the vial, now a little bit down from the top. She put it back in it's holder and her eyes widened further as it refilled by some unknown force, raising to full again.
It was real! Mary took a step back and stared in disbelief. Her excitement, however, soon turned to dread as she realized she had just drank an honest to goodness shrinking potion. With a start, she rushed over the vials and spun through until she found a picture on one that depicted a "restore" potion. She was quickly about to drink it, but then carefully set it on the table in front of her and sat in her kitchen chair. Waiting.
Slowly, she noticed a barely perceptible tingling sensation start to rise inside of her. It started in her stomach and seemed to flow outward to her limbs, until head to toe she was tingling. The potion must be working it's way into her system, she realized. Then came another sensation that was all together new and weird, as she felt what could only be described as a pulling throughout her entire body.
"Whoa..." Mary rose from the chair, and stared down at herself in shock. Though it was happening slowly, she could detect it happening. She found her pants and blouse were looser, and was actually watching her perspective lower as she visibly shrank smaller against the familiar things of her kitchen.
She wondered how small she'd go for how much she drank, eyeing the "restore" vial nervously, and as she became so small her pants fell off her slimming waist and pooled at her feet, she realized she must be at least six inches or more shorter.
Her panties slipped down her legs and joined her pants, she blushed as she saw they were wet with apparent arousal, and as her belly button lined up with the top of the kitchen table she gasped as the sensation began to fade. There was a final pulsation of shrinkage that coursed through her, and then Mary stood, in shock, realizing she was breathing heavily and quite turned on.
She felt the dampness of her pussy, her diminished form was a huge turn on, and her shirt now flowed down to her knees like a nightgown. It was irresistible and wonderful, she had really shrunken from drinking a shrinking vial. It was real!
She back in the chair, marveling as she felt like a child, lifted her shirt out of the way, and began to masturbate. It didn't take long as she fantasized about the seemingly limitless options sitting on her table. With a gasp and a wrenching spasm, she came, hearing her slightly higher pitched voice, and panting, satisfied, she reached for the "restore" vial... and put it back with a sly grin.
