"You could've warned me that you would jab me, Nancy!" "I know, it's just that we already agreed on the bet and it was almost midnight too. I didn't have time to set it up before it became November." As Nancy was gathering up her impromptu work area, the area in which Nancy injected the nanomachines began to shift about and change color. Still reeling from the shot of nanomachines, Charlotte began to feel that unusual change progressing within her.
The hair on Charlotte's arm grew out until there was a noticeable amount of hair. When Charlotte looked down at the injection site, all she saw was her mass of hair that became very fine, almost like fur. A bit freaked out at what happening, Charlotte made her way to Nancy to show the scientist what was happening. "Nancy! Can you look at your computer to see what am I transforming into?"
Annoyed that she just put away her laptop, Nancy took her computer back out and logged back in to see what program the nanomachine picked out. At this point, the hair growth on Charlotte's arm had made it to her shoulder and kept on going across her chest. While Charlotte's natural hair color is brunette, her fur-like hair begins to turn white and gain patches of orange and black. Almost like a Calico Cat's fur pattern.
"There we go. It looks like your first day of Triple N is being a furry of the cat varieties." Nancy looked up to see her friend becoming furrier and changing colors. "It was because I was dressed as a cat for Halloween, wasn't it?" Charlotte's cat "costume" that she wore for the holiday was a simple headpiece with ears, a tail that got in her way a few times that night, and some makeup for cat whiskers. But the nanomachines decided to take another step forward and add some more details to her costume.
Speaking of which, the transformation finally made it across Charlotte's chest and went down her other arm and torso and up to her head. The other arm follows suit like the first arm, with hair growth that shifts into fur and a palette change to white, orange, and black. Charlotte lifted her top off enough to see her belly getting whiter and fluffier as the transformation went down. As she rubbed her furry belly, Charlotte began to feel nubs hidden in the fur. Furthermore, prodding those nubs has resulted in Charlotte feeling rathered flushed, almost like when someone is feeling up her nipple.
"Hey Nancy, you own a cat right?" Nancy was not only watching her friend become a living furry but she also has been typing up on her computer to take notes of the experiment. When she finished typing down a note, she replied, "Yeah, her name is Buttercup. Why do you ask?" The transitioning cat girl approached her friend with her shirt still raised and presented her belly. "Could you rub my belly please, Nancy? I can feel something buried under my fur and every time I poke at it, I get aroused ."
Nancy smirked and said, "You want me to pet you Charlotte?" As the fur climbed up her frowning face, Charlotte disheartening nodded her head. With the cat girl's approval, Nancy reached ahead to "pet" her friend's belly. Just like what Charlotte said, there were little nubs under the fur along with some extra budding of fat behind them. "You know that cats have litters of kittens when they give birth right? Those "nubs" were your nipples Charlotte, and they gain some breast tissue behind them as well."
Charlotte was speechless about that revelation. That and the fact that her nose and mouth are fusing and changing into a cat's mouth. The nanomachines not only changed Charlotte's mouth on the outside but also gave her sharper teeth and a rougher tongue like a proper cat. As the fur goes past her eyes, they turn from human and blue to like a cat and green. Charlotte's vision is also affected as well, leaving her able to see in the dark but unable to see certain colors. As she looks through the window, Charlotte can see her street even though it is pitch-black outside.
Then Charlotte began to feel a slight pain in the seat of her pants and her head. "Nancy, there's something wrong right now!" Nancy tore her eyes away from another paragraph of notes to see her friend's ear begin to travel up her head and some growth sprouting above her ass. "It's your cat ears and tail. Your real cat ears and tail." As she said those words, the transitioning ears made it to the top of Charlotte's head and developed into a fluffy point with the same coloration as her body. Out of all the changes that affected her face, the only thing that wasn't changed was her original, brunette hair.
On the first day of Naughty Nano November, Charlotte has turned into an anthro cat girl. Covered with fur and topped off with ears and a tail that can move on its own, she looks like she has paid top dollar on a working fursuit. Nancy doubled and tripled check to see if the nanomachine had stabilized and once confirmed, she powered off her computer and finally put it away. "Congratulations my feline friend, you are a furry wet dream. What are you going to do next?"
Charlotte looked at her arm and started to lick her fur. Feeling slightly disgusted at what happening, Nancy looked away from her friend "cleaning" herself. "You know what, Nancy? I'm feeling tired so I'm going to sleep now. Make sure to lock the door on your way out Nancy and I will see you in the morning." And then Charlotte makes her way to her bedroom while taking off her "costume".
Nancy is a bit concerned about her friend kicking her out, but she also has important work to do in the morning so she exited all the same. As the night turned to day, Charlotte kept on sleeping. Even when her alarm clock and phone tried to awaken the sleeping kitty, Charlotte slept through it all. By the time Charlotte woke up, it was almost dusk. She looked at her phone to see hundreds of attempted phone calls and text messages from work and friends alike. "What a way to start a day, getting in trouble for sleeping." And she just milled about in bed while swiping and typing on her phone, half to her friend and work and the other half watching cat videos.
