"A male jaguar, 4-years transformation, living in the wild. You've also accepted participating in our breeding program, we thank you for that. Thou you denied permanent transformation and mind change, which is fine, we understand. Are those you transformation detailes?"
"Yes," Replyed Steven.
"Follow me to the lab than."
Steven followed. The scientist pointed towards a cage in the middle of the room. "Sorry for the inconvinience. but sometimes the petients can be... hard to control during the transformation. Enter the cage, strip, and we will start. I'll guide you throuhout the transformation, and for to weeks after. Then you'll be released to the wild. Are those terms accepted?"
"Yes." Said Steven and entered the cage. He was a bit embarresed at first, but he took off his clothing, and standed naked in the cage.
"Great! Now, let's begin. Oh, I forgot to mention, my name is Dan." Steve smiled towards Dan, and shaked his hand throu the bars. The scientist than returned to his table, picking up a syringe. He injected the syringe into Steven's shoulders, making him to wince in pain.
"I'm really sorry for that, but I guarentee you that this would be the only pain you'll experience throuhout the transformation. We make our formulas completly painless, so the patient won't suffer from his generous descision. Your changes will start accuring in around two minutes."
Two akward minutes have passed, with Dan looking at his naked body. Than Dan smiled, and pointed at Steven's ears. "Look! Your changes are starting."
Steven sent his hand up, feeling his ears move up, claiming a new position on his head. They shifted and changed, becoming more round and covered in fur. Dan reached out to the back of the room, and returned with a full-body mirror. "Now you would be able to see your changes," He said, placing it near the cage. Steven looked at his ears, and saw two curved, jaguar ears on his head. He smiled, becoming even more excited.
"And now, your feet and legs should start changing."
Steven looked at his feet, noticing his toes were disappearing, and the rest of his feet transforming into jaguar's paw. He walked around the cage, feeling his soft paws touching the ground, making no noise at all.
His legs were next. They cracked and shifted, thinned, and got into feline posture. Yellow and black fur started covering them, and Steven reached down and stroked his new fur. It felt amazing! Steven laughed, and Dan smiled. "I'm happy you enjoy that. Now it's time for your hands and arms."
The same changes happen to his hands, transforming them into jaguar paws. His hands took the same posture like his legs, changing into forelegs. He started losing his balance, and tried grabbing the bars, but his new paws couldn't hold it. He turned to Dan. "Dan, help me, I can't keep my balance!"
"Well, of course you can't," Said Dan, raising his finger. "You're going to be a jaguar, remember? Jaguars walks on all fours. Come on, get down. That's what you're supposed to do."
Steven blushed in embaressment. How could he forget? He fell down on all fours, feeling much more stable.
"And now, my favorite!" Said Dan. "Your new tail!"
Steven looked at the mirror, watching as a small growth sprouted from above his anus, lenghening and covering itself with fur. He could feel it. It felt like he had another hand. He focused, and felt it twitch from side to side. He felt much studier now. Wow, how could humans live without a tail?
"This is so cool!" He shuoted. Dan laughed. "I knew you'd love it! Now only a few changes remain. notice how your body starts to change."
And it did. His back and belly sprouted fur, and changed into feline body. He was completely stable now, and tried walking on all fours. It felt strange, but he also felt how agile and flexible his new body was. He turned his body, facing Dan. "And what now?" He asked eagerly, noticing his voice went down a tune. "Well... now it's the genital change."
Steven blushed. He could feel his oragn moves, repositioning itself right under his tail. He looked at the mirror, and saw a furry sheath covering his new spikey member. He looked at Dan in question. "The jaguar's penis is covered with spikes, so the females can't run away during mating," He said. "During our training, we'll cover that. And-Oh, your face start changing!"
Steven felt his head pushing forward, and his nose changed, forming a snout. His teeth grow larger and sharpened, and he tried to ask Dan about his new diet, but only a growl came out. He looked at Dan in slight fear. "Well, young man, jaguars can't speak, can they? I assure you, growling and roaring will be the only sounds you'll need."
Steven's eyes changed at last, completing his changes into a jaguar. He stood on all fours, and let out a powerful roar. Dan smiled, and opened the cage. "Now, follow me to your enclosure for your training. And, since you're now a jaguar, 'Steven' is just not fitting anymore. From now on, you'll be called Tywin. How'd you like it?"
Steven-now Tywin-roared in agreement.
"Alright. Now," He said as they've reached the enclosure, "Your new life as a jaguar will begin."
