A few moments after Tanya's near heart attack, she took a moment to lay on the couch for a minute. The whole experience seemed so real, but nothing happened really. Did someone spike her punch at the reunion? Or was she just really tired. She didn't want to worry about it though, she still had over an hour before she had to go to work so she put her head back against the couch and enjoyed the new fluffy cushions under her butt... "Wait..." She started to feel her backside tickle. Something wasn't right. "What's going on back there?" She asked sitting up and feeling her lower back only to feel not smooth skin... But fur. Alongside the fur, was also a lump in her lower back that she could feel growing out gradually with her hands. "That... No! That can't be it..." Soon after she felt two additional growths in between the first. Her eyes shot wide open as she stood up and looked back to see her lower back was getting covered in silver fur with three slim bumps. She realized she was growing not one, but three tails.
"Oh my God..." Before she can say anything else, an overwhelming presence started to engulf her body. She fell to her knees clenching to the arm of the couch as her ears started grow and point upwards, and her face started to stretch out. She could feel her ears travel up her head while also being covered in fur like her backside in which the tails started to grow longer and the fur started thinking around them. She watched her nose pushing forward and turning black as the same silver fur spread from her newly formed muzzle all over her face. Fur started to spread from her face engulfing her chest and belly in the process. Tanya's chest exerted a lot of pressure as her breast started to grow from a respectable B, to, C, all the way to D cup, making the buttons on her uniform pop. Her arms gave out strength and she slumped down to the floor to see her hands grow thick pads on her fingers and palms and her nails sharpen and thicken into claws.
"UGH! How long is... This gonna last!?" Her frustrated grunts turned to pants as her shoes burst open revealing what happened to her hands also got to her feet, turning them into paws. Her feet started changing shape as her heels started to stretch away from her forefeet making it difficulty for her to stand properly as the silver fur spread across. With the fur covering the last of her legs, the three tails started growing longer and fluffier, making Tanya pant in excitement. She started painting faster as her changes accelerated as she grew 6 additional tails one after the other, all reaching 3 feet long and all swishing spasticity in different directions. Tanya started screaming as her eyes started to glow white. Glowing white markings showed up on her ears, eyes, and nose while her tail tips glowed white and completed Tanya's transformation into an anthro kitsune.
Tanya, still huffing from the intense experience tried to stand with her new digitigrade feet, using the arm of the couch as support. With some difficulty, she managed to stand on two hind paws. Everything as she knew felt wrong, her twitching ears and nose, fur all over her body, not to mention her bigger bust and the nine tails fanning behind her. She opened her glowing white eyes and saw her new body from the chest down. "Wha... Why did this..." She felt a presence behind her and turned around to see the white and red fox in an anthro form similar to Tanya's.
'Welcome to the pact sister. How do you feel?'
