"Now then, shall we start with the next conversion?" asked Dr. Stein, with Ping acting as his translator, "Tuxing, perhaps you would like to go next."
Tuxing, the youngest of her sisters at 14, had seen several things that a young girl shouldn't have. That kind of improper exposure would scar a person badly. And while there were some mental scars along with a few physical ones, the experience made her wiser beyond her years. She was a lot more mature than girls her age usually were. She looked Dr. Stein in the eye and said, "I'm ready to be changed."
Though Tuxing was mature for her age, the other girls still felt the big sister instinct to look after her. Jinxing stepped forward and asked, "Would it be possible if you could change us both? We can still share the room."
The FBI agent frowned a bit after the request was translated. "But the two of you wouldn't have privacy," he said.
"So? There's nothing between the two of us that we haven't seen before," said Jinxing.
"It's true," confirmed Tuxing.
"And we're both going to become big cats anyways. Tuxing will need someone to help her out after she's transformed," said Jinxing, "I think there will be enough room for the two of us."
"I suppose we can accommodate that," said Dr. Stein before looking at the other two sisters, "Though with your animals, there may not be room for you to change in the same place."
"It just means less time for waiting for me," said Shuixing with a shrug.
"As long as my sisters will be able to defend themselves, I won't object," said Muxing. She probably would have volunteered to change with Tuxing herself. As grateful as she was to these men, she wasn't about to let her guard down any time soon.
"Well, let's proceed then," said Dr. Stein as he led the girls into the transformation room. They did seem uneasy about the bed, but they weren't freaking out about it. Probably because the two of them were together as well as Huoxing completing her transformation without being molested. "Now, snow leopards aren't very large, so Jinxing shouldn't be getting too much larger. Tigers are a different story and Tuxing is going to outgrow Jinxing by quite a bit. And not just because of her double-dosing."
"What kind of tiger is it?" asked Tuxing.
"It'll be a Bengal tiger," said Ping.
"Not a South China tiger?" asked Tuxing.
"No," said Ping. It was pretty easy for her to guess why Tuxing asked that. "Is it because you wanted to be like Master Tigress?" Tuxing nodded at that. "Well, we have a limited amount of access to tiger DNA right now. And South China tigers are too endangered right now for any of them to be uplifted right now. They need as big a gene pool as they can get so they don't go extinct."
Tuxing absorbed this information rather easily. It wasn't too hard for her to understand. "So what about my species?" asked Jinxing, "Is it a particular kind of snow leopard?"
"There's only one species of snow leopard," said Dr. Stein as he got the shots ready, "There's some debate about whether there are subspecies, but there isn't solid enough evidence to prove it." After that, he walked over to Tuxing and injected her shots into her arm. Then he moved over to Jinxing and gave her shots. "Welcome to Animalia," he said as he and Ping left the room.
Perhaps because Tuxing was injected first or because she had the bigger changes to go through, she started showing signs of transformation first. White fur was already starting to appear on her face and on the undersides of her arms. Parts of her skin were starting to darken with extra pigment, tigers possessing stripes under their skins. She winced and sat on the bed as her shoes felt too small.
"Let me help you with that," said Jinxing as she knelt down. She had kicked off her own shoes as soon as Dr. Stein and Ping had left. "Probably should have taken them off first," she said as she helped peel off Tuxing's shoes. Tuxing sighed with relief as her feet unclenched. They were about halfway to digitigrade paws now, her toenails sinking into her toes as they became retractable claws. As Jinxing stood up, she noticed that Tuxing was getting taller, a noticeable gap now apparent between her shirt and her pants, which were starting to look tight. "It looks like you're going to get too big for the rest of your clothes," said Jinxing.
"I...wanna grow out of them," said Tuxing, sounding rather flushed, "It feels..." She couldn't find the right words to express herself. Yes, the tightening clothes were uncomfortable, but the feeling of her body maturing overshadowed that. She had already started puberty, but since she was only 14 and Chinese women tended to be small-chested, her breasts hadn't developed much. Now they were swelling out at a fast rate, already tearing through her training bra and making her shirt too snug. Her pants were also straining as her legs grew longer and her hips were flaring out. They were splitting down the back as her behind started filling out, which gave her growing tail enough room to move.
Jinxing was drawn to her own reflection in the mirror. The silver fur of the snow leopard was spreading over her body, with the brownish spots popping up. She watched with interest as her ears moved further up her head as her mouth pushed out into a feline muzzle. She extended the claws on her hands and ripped at the back of her pants, letting her tail grow out more. Her pants were also getting tight as her ass was filling them up more. Jinxing reached up and pulled off her shirt, revealing her tightly-packed bra which was getting too tight around her growing breasts. One slash severed the cups, allowing her breasts to bounce out. Jinxing cupped them, giving the leopard equivalent of purring as she did.
"Jinxing...I...can't..." gasped Tuxing. Jinxing turned to look at her not-so-young sister. Her clothes were very tight against her body now, but they weren't breaking fast enough. Jinxing hurried over and help claw off the remainders before Tuxing couldn't breathe. Tuxing sighed with relief as she felt a lot less constricted. Her fur and stripes had finished growing in by that point. Interestingly, her fur was more yellow than a tiger's typical orange color. Without her clothes, it became very evident that Tuxing was nearing the end of her maturation. What was once a young girl's body was now a very well-endowed woman's body. Jinxing thought Tuxing's breasts were bigger than her own, but that could just be because Tuxing was bigger than her. Even sitting down, she was almost at eye level with Jinxing's neck. Her face was already looking more like a tiger's, her gasping mouth showing sharp teeth. But it wasn't just because of her near-strangulation that Tuxing was gasping. Her nipples were standing out through the fur and Jinxing's sharper nose could smell her arousal.
As Tuxing's body started to calm down, she sensed her changes were done. "That was...incredible..." she said. She paused as she spoke, marveling at her new voice. It had matured to a real woman's voice, deeper than she was suspecting. Probably because she was a tiger now.
"You look incredible," said Jinxing, her own voice deeper and silky, "Come look in the mirror." She reached out a hand and helped haul Tuxing up. It took a bit of effort because of how heavier Tuxing was now.
Tuxing looked in the mirror, scarcely believing the tiger woman staring back was her. She brushed a hand through her black hair, which got longer with her aging. The raven color of her hair really stood out against the yellow and white of her striped fur. Her breasts, hips, and ass had grown out to give her an incredible hourglass figure. But she wasn't just all curves. She flexed her muscles, marveling in how large and well-defined they were. "I'm...gorgeous," said Tuxing.
"Well, if you like muscle babes," said Jinxing, standing beside her and posing, "Now this is gorgeous." The snow leopardess was a real beauty herself. While her muscles weren't as bulky as the tigress's, her supple curves were emphasized by her thick, plush fur. Her silver spotted fur contrasted well with Tuxing's golden striped fur.
"I guess I'm the big sister now," said Tuxing, easily standing over Jinxing by at least a head.
Jinxing poked Tuxing's nose lightly and said, "Think again, little sister. You may have a woman's body, but you don't know how to show it off as well as me."
"I might be showing off too much," said Tuxing, noting that she was naked now.
"I'm sure they've got some spare clothes around here for you to wear," said Jinxing, "Let's hope they can hurry with that. I want to show our new bodies off and our other two sisters still need to change."
