Parker contemplated the gun, considering its potential. His first choice would have been to mess with his family - he didn't want to hurt his dog or test it on himself, obviously. But his family wasn't home. As he was considering this, he glanced out the window. His friend Bill - pretty much the same age as Parker - was walking down the sidewalk just outside. A devious smile spread across Parker's face. Bill was his "friend" in the sense that he tolerated Parker, but he never really went out of his way to hang out. Perfect initial test subject. Parker opened the door and waved.
"Hey, Bill, come here! I've got something I want to try out, and I need another person!" he yelled. Bill nodded and jogged up to the door. "What is it?" he asked. Parker showed him the transformation gun and explained what it was. "I need to test it out. It's probably a hoax, but still." Bill nodded and said, "Yeah, probably so. Just make sure it's something minor if it does turn out to be real." Parker chuckled - what he had in mind was far from minor. He stood back, aimed at Bill, and pulled the trigger. Sure enough, a barely-visible beam of light hit Bill, who promptly doubled over and began to convulse violently. "What... did you... do to me?!" he demanded. Parker just kept grinning as the changes began.
First, orange fur grew all over Bill's body, while his face began to elongate, forming a fox's head, and his feet bent and became digitigrade. His ears shifted to the top of his head and became pointed, while a monstrously fluffy tail exploded out the back of his pants. "I said MINOR!" Bill yelled. "Oh, it's far from over," Parker replied. Bill, now fully an anthropomorphic fox, let out a little whine and folded his ears back. Sure enough, he doubled over again as he became very much a she, "his" maleness vanishing. Predictably, two large-ish breasts exploded out of her chest, while her torso thinned and became feminine yet athletic, and her hair went from short and brown to just past shoulder-length and red. Finally, her clothes changed from a T-shirt and shorts to a skirt and top. Trembling, the now very female and very attractive Bill looked up, tail curled between her legs. "Is... is it over?" she said, meekly. Parker reached out and stroked her cheek fur. "Yes, it's over. This thing really is powerful. Oh! You need a new name." He tapped the gun a few more times and fired another shot. A collar appeared around her neck, with a name tag that read "Bella." No longer totally frozen by fear, she reached up and looked at it, then looked at the other side. On it was written, "Owner - Parker Adams" with some contact information.
"What is this?!" she demanded. "I'm not your property!" Parker shook his head. "No, Bella, you are. And you know it. I'm not going to be cruel, but it's always been kind of my fantasy. Look, just to prove it, I made some limited mental changes. Strip down. Right here, right now." The newly-christened Bella instinctively rushed to obey. Soon she was standing there, completely naked. Oddly, she noticed, she didn't WANT to strip down, but she didn't feel the shame she should be feeling. That fact made her angry. "What did you DO to me?!" she said, sobbing slightly. "There, there," Parker said, petting her on the side, "I just made some minor changes. You're obedient to me, yes, and doing certain things will feel natural now, but you're still you." Bella calmed slightly. The petting did feel good, and at least the mental changes were only minor. At least she was still allowed to feel upset about the situation. She sighed.
"May I get dressed again?" she asked, realizing after the fact how utterly servile it sounded. "Yes, please. I just wanted to get the point across," Parker replied. Soon she was dressed again, and sat down on the couch. As she fully comprehended the situation, she started to cry a little. "So. You turned me into a fox-girl. And I'm yours. Totally obedient. Obviously I can't do anything about it. So what now?" she said, blatantly crying at this point. Parker sat down and pulled her close, letting her cry onto his shoulder and stroking her fur. "I suppose I'll let you adjust some - this new life will take some getting used to, obviously. I do have plans for other people, if you'd like to join me. I might even let you use the gun a bit," he said, smiling. Bella's ears perked up. "Really? I mean, obviously I wouldn't use it on YOU, but... I would like to give it a try. And... I guess it's the mental changes you made, but I like the thought of spending time with you." Parker grinned. "Don't worry, my lovely fox. We're going to have fun today."
