You take a few extra seconds to revel in the moment. You've been playing around with the gun so much lately that you have an inkling to keep going, but then you realize you're exactly where you want to be: you're now shrunken with a giantess slave totally under your control. You've always fantasized about having a giantess around to play with, but you just tried it in reality, and the real-life girl wouldn't play along. Now, though, thanks to the wonders of this gun, she'll do anything you want.
"OK, Kristen," you say. "Here's what we're going to do today. You know your boyfriend, uh, Kevin or something? The first thing we're going to do is go find him."
She frowns, confused. "But why?"
You frown back. "Bitch, slap yourself in the face, hard."
Kristen follows your command, and you laugh. "Don't ever question my instructions again. You are a toy, and you will do whatever I say."
You exhale. That felt good to say. You watch her rub her cheekbone where she just slapped yourself. "Anyway, to answer your question, I've got one hell of an idea."
