"Did you hear that?" said Greg, taking his lips off Kara's.
"Yeah, that's just Rikki, our cow, remember?" said Kara, a bit disappointed at the interruption. She and Greg were seated at the end of Kara's bed, the door to her room closed for privacy.
"Jeez, how do you put up with having an animal like that around?"
"We just do. Besides, the milk is worth it", said Kara, untying her ponytail to let her long blonde hair spill over her shoulders.
"You're worth it", mumbled Greg, giving Kara a quick kiss.
"Heh, tell me about it", said Kara, wrapping her arms around Greg as they fell back onto the bed. Neither of them knew that the Chronivac had moved on and, finding two targets in close proximity, decided to alter them at the same time.
"Mmh..." Greg paused from pushing his tongue into Kara's mouth. "I feel funny, babe..."
"Me too", said Kara, sitting up and scratching her arms. She decided to move forward though, and pulled her shirt off. But instead of looking at her lovingly, Greg had a shocked expression on his face. "Wha-? What's the matter sweetie?" she said, concerned. She followed Greg's gaze down to her chest, where soft blonde fur was starting to grow. "What the fuck?" she screamed, feeling it in horror. Then she turned to look at Greg. "N-no! You too?" Greg felt his face as white fur began to break out all over it, standing out over his tanned skin, while his nose and mouth pushed out, making his front teeth stick out more and more.
"What's happening to us?" said Greg, looking at his girlfriend as she got fluffier and fluffier. Kara twisted around, trying to get a better look as a furry blonde tail pushed out above her pants, swishing nervously. She felt her abdomen as a row of nipples formed on it. Greg's own growing tail was long and pink, like his changing hands and feet and growing ears.
Kara tried to get up, but found herself falling onto all fours beside the bed. She was starting to shrink, her clothes sagging on her as she got smaller. She looked up at her boyfriend, watching her with concern from the edge of the bed. Greg was shrinking too, but even faster than her. As he got smaller and hairier, Kara began to realize just how tasty he looked.
From his position atop the bed, Greg's confused mind was also changing as he climbed out of his clothes. As he stared at Kara, his love for her was slowly replaced by a growing sense of fear. She was looking back at him with big yellow eyes, her pointed ears flicking in his direction as she licked her lips... As their clothes and human thoughts vanished, a collar with a tag reading "KARA" appeared around Kara's neck, and she got into a feline crouch.
Now thinking only mouse thoughts, the white mouse ran for his life a split second before the sandy blonde cat pounced onto the bed. He ran for safety with Kara in hot pursuit. If only he hadn't closed the door behind them...
Meanwhile, all traces of Kara's presence vanished from the room as it became a spare bedroom. The Chronivac beeped and moved on to the next target, unaware of the chaos it was causing.
