"Hey, I had a question." Jamie turns to look at you. "Exactly how small can you make me?"
"I have no idea, let me check those safety guidelines the app mentioned." I thumbed through the options until I found the 'Help&FAQ'. I was fascinated by my now-smaller hands, they looked so delicate. "Here we go, there are safety protocols for shrinking to less than 1 inch tall, something about your lungs becoming unable to breathe air efficiently."
Jamie nods. "That was something else I was wondering about. As I get smaller, oxygen molecules become larger for my lungs."
I continued. "There are some transformations that can allow you to survive at sizes below 1 inch, but it starts talking about microscopic dangers like bacteria and stuff."
"Yeah, no thanks, I mean, I want to try being super small, but it has to be under controlled circumstances. I don't need to get eaten by a bug." Jamie shivers, and moves closer to Annette, who hugs her.
"Which reminds me, ok, here we go. This device is primarily intended to alter the age of the target, with necessary options to reflect awareness, clothing, and prevent drawing undue attention to the user. As you may have noted, a wide variety of other transformations are possible, but a serious risk is deviating too much from what can be considered 'human'. As subjects become less human, it can have drastic effects on their mental health. It is suggested that subjects be allowed to remain at least 50% recognizably human, such as turning someone into a mermaid. Consider carefully physiological changes when transforming a target into something that is part herbivore if the subject is a carnivore, or part reptile if the subject is a mammal."
"Woah, wait, you could make me into a centaur or something?" Jamie whistles lowly. "That could be cool."
"I thought you wanted to be tiny?" You ask.
"Hey, I can do both." Jamie blushes.
"So what kind of controlled circumstances were you talking about, Jamie?" Annette speaks up.
"Oh well. I just want to make sure I'm not in any danger, that you guys won't be able to lose me. Apparently I'm pretty tough now, and if I remember my science, falls aren't a big deal for really small things." The tiny girl has a thoughtful look in her eyes. "Plus, since I keep a lot more strength, I'll basically be a supergirl, like how an ant can lift ten times it's body weight. I bet I'd be able to jump like a flea."
"Mobility seems like something that could be a problem. What if we gave you wings so you could fly? We can apparently make you up to half bird." Annette adds.
"Ooh, like, angel wings? I dunno, I'd need a big wingspan, and I wouldn't have tail feathers or anything. I mean, you could give me a tail, I guess."
The longer you talk to Jamie, the more you realize she's very intelligent. Both of the girls are smarter than you, but by how much? "One thing at a time. Let's shrink you first, see how that goes. So for a controlled environment, how about we put you on the kitchen counter. It's white, so we can see you easily, and then we could put stuff on it for you to interact with."
Annette frowns slightly. "I was hoping she'd interact in the bedroom."
Jamie laughs. "Oh we'll do that, but I don't need to be quite that small for what I have in mind for you, 'Nette." She grins.
Annette's eyes widen. "Oh. Oh! That's good to hear, I'm a little wound up."
"I can tell, girlfriend. You're a little nymphomaniac right now, huh?" Jamie teases. "Well, I know shrinking does the same thing to me. Let's do this!"
You head to the kitchen, and you shrink Jamie to about a foot high, then pick her up and set her on the countertop. You place a penny on the table next to her. "For a size reference."
She nods. "Let's do this!"
You set her to shrink slowly, about an inch per minute, and you and Annette watch, barely even breathing, as Jamie dwindles smaller, smaller, and smaller still. Finally, she's so tiny that she can step onto and sit on the penny's surface.
"Can you hear me ok?" Her voice sounds higher pitched, like a cute little pixie, but she's perfectly audible.
"Loud and clear. So what do you want to do first?" You're curious what she has in mind.
"I want to try eating at this size. Do we have anything that isn't pizza?"
Annette goes to her fridge, opening it, then staring upward. "Ugh, hard to be a kid an adult-sized world. There's some jello cups on the top shelf."
"Ooh, jello!" Jamie giggles.
You get the jello cup out and open it. You open up your hand and let Jamie clamber onto it. She's so light that she seems as agile as a monkey. She perches on your fingertip, grinning ear to ear.
"Man, it's all I can do to keep from touching myself, I'm so turned on right now." She giggles.
You bring her to the lip of the cup, and she steps onto the jello. The surface tension is so high she can't sink in the stuff, and she bounces slightly as she walks on it.
"It's like a bouncy castle!" With some difficulty, she gets a tiny piece of jello in her hands, and puts it in her mouth. "Oh this is weird, it tastes right, but it's hard to chew."
