Tinker was a stallion. A big, Luna-sized dragonpony stallion, with paws, claws, big leathery wings, fangs, horns, and dragonish eyed. He even had magic, and a dragonlike tail, oh, and a knotted stallionhood to finish things off. But Tinker liked to try the other side of things, and lately, he, or she, had been living life as a mare. Tinker was still a big pony as a mare, but with more emphasis on curves than muscle.

It was fun! Heck, Tinker had gotten so good at the spell that she didn't even know if she preferred her stock gender anymore, so she may as well call herself genderfluid. Either way, it didn't really matter. What mattered was fixing the broken Pontendo Switch in front of her. Tinker was sitting at her desk in her shop, with the setting sun streaming in through the large glass picture window. Problem was, Tinker's body had decided to go into a nasty heat, and she was at war within her head over it.

One part of Tinker wanted to power up her spell and fix the heat, but she had given it one attempt and it hadn't worked, so that avenue had been given up on for now. Another part demanded that she find the nearest stallion and jump him, but she didn't want to follow that one either, since she had ran out of anti-pregnancy potions. Lastly, the most stubborn part of her was focused on one thing, fixing the console in front of her.

By the time she did fix it, Tinker had soaked her seat, but she didn't care. She grinned a big smile as the console began to boot up, as she won the victory within her head. "Suck it, Heat, ain't nothing interrupts ME when I'm fixing something!"

But then the bell to her shop rang, and Tinker looked up with a textbook Deer-In-Headlights expression. The door had opened, and inside walked a _massive_ Zebra stallion. Normally, Zebras were smaller than pony stallions, but this one was bigger! Hell, he was bigger than her!

Before he could get close enough to smell her, Tinker lit up her horns, putting every ounce of focus she had into powering up the spell that would turn her back into a stallion. And despite casting the spell in the same manner that she always did, it simply didn't work. And that was a problem. "T-This is fine..." She muttered, quickly putting away the switch as her ears went down.
