The tiger girl slowly stretched to impossible proportions and pulled herself off Derek's lap. She idly scratched her bra with her newly-formed tiger paw.
"How did you sleep?" Derek asked.
"Not enough," Sonya yawned. Derek admired her sharp teeth. "I think I'll be sleeping a lot more lately."
"Maybe, if we keep you like this for a while," Derek said. Sonya had begun licking an arm. Derek waited until her grooming reached her large paw. When it finally did, Sonya stroked it twice and then stopped. She stared at it quizzically, then lifted her other paw.
"What did you do?" she asked, more confused than annoyed.
"I just thought I'd have a little fun. What else would I have amused myself with while you were planted on my lap?"
Sonya giggled. "I doubt I can do much with these, though."
"We can work on that later," Derek said. He reached up to take her collar off. Sonya's arms hooked around his and he stopped before he could undo the clasp.
"Wait just a minute." She stood up, balancing effortlessly on her new legs. "So my tail is longer, I've got paws...what else?"
"There's one more thing. I'll let you guess."
Sonya sneered playfully. Her yellow eyes surveyed the rest of her form. "I can't tell if you changed colors on me," she said.
"It's not that. Try shaking your head around."
Sonya did. The flurry of wavy red locks startled her. She ran her paws through the mane, which was now reaching down to her butt. "Oh cool!" she shouted. "You are the best boyfriend ever."
"Now can I please take my turn?" Derek said. He got off the bed and this time, Sonya allowed him to remove her collar. He was about to put it on himself when Sonya shouted.
"WAIT! My paws!"
"So?"
Her eyes narrowed like a predator about to jump its game. "I can't take the collar off you if I don't have hands."
"Oh. Thanks for thinking about that," Derek said sheepishly. Here he was trying to have a little fun and he got so caught up in the nonsense, he almost made a damning mistake. He put the collar back on Sonya. "You can have your hands back, but they'll be a little tiger-like. With claws and stuff."
"'And stuff'," Sonya said. "I'm amazed the collar works that vaguely."
"I think the spell is partially mental," Derek said as they watched Sonya's fingers return. They kept their white fur, padding and retractable claws, however. "The verbal command it just a cue for the changes. So far all your changes have come out exactly as I pictured them in my mind. I mean, exactly. That can't be a coincidence."
The collar was off once again, and Sonya took it in her claws. "So that makes this all the easier," Sonya purred as she attached it to Derek. "I think I've already got some changes in mind..."
