Mrs. Li answered the door. To Mikey's surprise (and delight) she was wearing tights.
"Mikey!" she said with a faint accent. "I'm sorry. I forgot you were going to eat here tonight. I was finishing up my workout."
"That's all right," said Mikey. "I don't mind. Go ahead and finish up if you want to."
"Okay. Would you like to watch me?"
"Sure!"
Mikey followed her into the living room, where she had a mat on the floor. She got down on all fours and began to stretch out her legs and curve her back so far, Mikey was worried she would break. Mikey couldn't quite thing of the word "graceful," but that's how Mrs. Li was moving. And she noticed him watching her.
"Do you like my exercises?" she asked.
"Yeah! I've never seen exercises like those before," said Mikey.
"Those are dancer's exercises. I've done them most of my life to stay slim. That one was called the cat, because I move like a cat. Watch and you'll see!"
Mikey did watch her. And she WAS moving like a cat! Mikey could see her stretching as a cat stretched, turning her head back, arching her back.
"Could you think of any way I could look more like a cat?" she said.
That was the last thing she needed to say to Mikey. He stared at her and mumbled.
Mrs. Li's ears became pointed. A long, black tail poked through a hole in her tights and grew. Light brown fur covered her body, except for her ears, around her eyes, and her ands and feet. And the nails on her fingers and toes changes, becoming curved, more pointed.
Mrs. Li stood up and smiled at Mikey. She noticed with a little laugh that Mikey was obviously turned on by what he saw. But she didn't realize that her smile showed off a few long, sharp teeth among the normal ones. And she didn't notice the whiskers over her mouth.
Mrs. Li had changed into something not entirely woman, not entirely cat, but an enticing combination of both. She didn't notice. And Mikey found out that her mind was part cat, too.
She got back down on her hands and knees and SLINKED against Mikey, purring loudly as she did so.
"I -- I gotta go to the bathroom!" cried Mikey, running out of the room. Mrs Li smiled inwardly as he left.
