Dan lay in his bed with a knot in his stomach. "My sister really is a witch," he thought out loud. He felt his long ears twitching around on his head as he amazingly managed to relax a little bit and finally fell asleep. He dreamed about Kat's party. He dreamed that the guests were princes and Kat turned them all into frogs.
Sometime later, Dan awoke with a sharp pain as he felt his sister's hand yanking hard on ... something. He jumped up and shouted and looked around.
"Looks like your changes are coming along quite nicely, my pet," said Kat.
It was troubling to see her holding a long gray tail, smirking and waving it back and forth playfully. It was even more disturbing to actually feel it happening through the tail.
"Hey, give me that," Dan said, grabbing his new appendage back from her in a swift motion.
"I already did, heh, heh," she said, referring to the spell.
Dan ignored her quip and focused on the new body part he was holding. He gave it a light tug of his own, not nearly as hard as Kat pulled it. He traced his hand down to the fluffy tassel, then he reached around behind him and felt the thick base where it merged up into his back. Then he let go and just watched it hang down.
"Now, now, there's no hurry because you're going to have that thing for a quite a while," said Kat.
Dan's ears drooped, reminding him that those were going to be around a while, too. He was going to be an animal, and that animal was a donkey, the one animal he was least okay with becoming.
All of this was distracting him from the full bladder he had amassed during his nap. When the urge finally hit him, and he just groaned and hurried to the bathroom, not bothering to say a word to his sister. On his way there, he felt even more changes happening that spurred him into a run.
