Colin smiled. He'd been into furries since he was thirteen, and with this power, he could make himself into one, and he wouldn't even have to worry about getting a new ID.
He went back into the kitchen, where his sister was still eating, and not treating her brother's sudden body type change as anything unusual. Colin remembered that, according to his dream, any question of his answered "yes" would change the world so it was always that way, and only he'd remember otherwise. So, he guessed, from her perspective, nothing unusual had happened.
Colin suddenly realized, he'd need to be careful how he spoke from now on. If he wanted to genuinely know the answer to a yes or no question without changing it's answer, he'd need to word it a different way.
He shook his head. He'd worry about that later. Now was not the time for caution. Now was the time for living the dream!
First, a little something for extra fun. "Is casual public nudity accepted and legal for any kind of anthro?" He asked.
"Yes," Jane answered in monotone. Nothing happened as far as Colin could see, but he didn't expect anything to, yet.
"Am I an anthro dragon, with the ability to breath fire and fly regardless of what the laws of physics would say?"
"Yes."
In an instant, Colin felt his body getting warm. Hair vanished all over his body, as thousands of tiny blue, interlocking scales grew over his skin instead. Thicker, duller blue scutes formed on his chest. He felt pressure in his fingertips as the bones stretched out through the skin and sharpend, the fingernails disappearing as these new white claws took their place. His feet changed much as his hands did, sharpened talons forming on his toes.
His clothes began to strain as his body grew a little bigger and a tear appeared in his pants as his spine began to grow, forming a thick tail. The new appendage soon pressed through the back of his pants, bursting the waist, and allowing his pants and underwear to drop down, revealing that his manhood had already retracted into a new sheath.
His tongue suddenly split at the tip, his taste buds becoming far more sensitive as he flicked it in and out of his mouth. His teeth began to sharpen, more and more growing in as his jaws stretched into a long, aligator-like snout. His ears became thinner, and began to fan out, and he felt a pressure from two points in his skull as two horns jutted straight out of his head. His eyes turned a deep green color, while his pupils narrowed.
Finally, he felt pressure in his shoulders, as two new limbs grew out and pressed against his already too-tight T-shirt. The shirt soon tore open, and he shook it off, flexing the two new arm-like limbs behind him. Their fingers grew much, much longer, a thick, leathery membrane forming between them, completing Colin's new wings.
Colin flexed his new appendages and gazed over his new body in awe. The young dragon could feel raw strength flowing through his veins, his naked form bulging with muscle. Delighting in all the new sensations, Colin gave into a primal urge, and let out a deep, powerful roar!
"Colin! What are you DOING?" Jane shouted, covering her ears. "You're gonna wake up mom and dad, and the neighbors too!"
Colin shook himself out of his stupor. "Uh, right, sorry!" he stammered. He quickly tried to think of a good question. "Are mom and dad NOT gonna wake up from that?"
"Yes," Jane said dully, as groaning could be heard upstairs. He face suddenly went back to normal. "Yes, they're gonna wake up! What did you THINK would happen?"
Colin panicked. Great, so simply phrasing things as a negative would only make what "yes" meant ambiguous. He quickly rethought his question. "Did our parents and the neighbors sleep through my roar?"
"Yes," Jane said, as the noise coming from upstairs quieted down. "Just... don't press your luck like that again, okay?" She continued as the trance ended.
Colin nodded, glad that mess was over. Then, it suddenly dawned on him; Jane reacted to the roar, but not to his being a dragon, or naked. He wanted to test and double check it, opening his mouth to ask "Hey, do you notice anything different about me?" Before he stopped himself. That would either mean she'd suddenly realized that reality HAD changed, or she'd notice something ELSE different about him, and that unspecified change would become reality. This power would be a little trickier to use than he thought.
"I know it's a weird thing to ask, but what do you think about me being a dragon?"
Jane looked up from her meal. "Well, as long as you aren't doing stupid stuff like roaring as loud as you can early in the morning, or setting fire to things, I'm fine with it," she answered as casually as someone would answer a question about a hairstyle. "I'll admit, I'm kinda jealous YOU got the genes for flying and super-strength," she whispered.
Colin grinned slightly at his sister's last statement. "And what do you think about my going around naked?"
"You're an anthro, you do you, I guess," she shrugged, "I think it looks nicer when you wear something, but it's not like I can make you.
It worked perfectly! With this power, Colin realized, he could do nearly anything with a couple carefully chosen words! He could make himself rich, or ruler of the world... But honestly, those sounded kinda boring, on second thought. Why go for money, when you could go for what you would get with the money, directly? And ruling the world's too much responsibility, anyway. No, for now, he would leave mundane concerns aside. He could do the impossible, so why settle for making things he could have MAYBE done before anyway happen, when you can get experiences no amount of money could buy? Now it was time to start making things interesting.
