“So...” Tiffany whispered, her synthesized voice dripping with apparent lust. “What are we going to do with miss Kaylee? Would you like me to stop her shrinking process when she returns to her normal size? Would you like her to continue shrinking her down? Ooh, what if we removed her unaware condition? Perhaps let that tall body you adore slowly shrink out of her clothing.”
“Tiffany,” Chris gasped in shock, walking away from his roomie’s door and nearly panting with embarrassed arousal. He sat on the couch and squeezed his thighs together, letting his hard erection rub against his underwear.
“Imagine, Chris...” Tiffany whispered again, enjoying the human’s moral resistance and trying to break it. “Holding her in your arms as she shrinks ever smaller. Feeling her body reducing. Her naked form becoming more adorable. Picture holding your friend in your hand, looking down on her shocked expression as she grows more and more helpless by the second. Imagine looking down on her on the tip of your finger.”
“Yes...” Chris blushed, grinning, closing his eyes. “Yes, Tiffany. We... we can just change her back and make her forget, can’t we?”
“Of course we can. I have that power, darling. Embrace this... have fun. Tell me what you desire.”
“When she reaches her original size...” Chris whispered. “I want you to remove her unawareness, the adjustment of her clothing, and slow her rate of shrinking to one foot every hour until she’s... she’s... as small as a grain of sand.”
“Theeere.” Tiffany whispered with deep and obvious excitement. “Doesn’t that feel good?”
“Y-Yes...” Chris gulped.
“It’s done, darling. She’s just a little larger than her normal size now. When she returns to her original stature, the process will begin anew and your desires will take effect. You might consider what outside force might be making her shrink. I would advise against telling Kaylee you used a quantum remote to force her body to shrink.”
“Oh my God.” Chris suddenly gasped, red faced. “Y-You’re right.”
“Think of a plausible explanation. Perhaps it’s something in the water, perhaps she came into contact with a chemical that is causing her to retract. I can make that a reality.”
“What about mass changes? You said...”
“Cascade, my love. A quantum cascade. All things are interconnected therefore changing something in reality must trickle down to all things in reality. Say we make the water be the source of her size reduction. That must mean that this entire city’s water supply must shrink people if they drink it. Perhaps the amount of water Kaylee drank, say... in her juice, causes her to shrink as small as a grain of sand. Imagine what will happen to others who have drank more. Or less.”
Chris’s eyes widened trying to do the mental math... and realizing what Tiffany was saying. “A cascade. Of consequences.”
“Precisely. So... what is it that is making the girl shrink? We must protect ourselves, after all. It wouldn’t do for people to know you have me in your possession at all.”
“A... a combination of things,” Chris whispered, realizing the subtle implications. “She was cleaning the kitchen. The cleaner she used reacted with her... her... shampoo. And... and her brand of deodorant. Then, the specific juice she drank activated it.”
“How perfectly rare!” Tiffany cooed. “Ah, she’s nearly her original size now. Are you ready to have some fun?”
