Theo paced through some options in his mind, but eventually settled on making Hannah into a half-monkey. It was what the Chronivac recommended, and he thought it made her look hilarious. Being a little dramatic, he wound up his hand and clicked the apply button, then closing Hannah's profile. He sat back in his chair, waiting for the eventual drama this would cause.
Meanwhile, Hannah was reading a book upstairs in her room. She was always bookish, putting in maximum effort into school and studies in her free time. She was laying on her bed, a little bored and still disgusted with what Theo said earlier. As she went to flip a page, she felt a sudden itch down her back. She scratched her ass involuntarily, feeling great as short brown hairs dotted around her lower back. As she scratched, a tail began to work its way out of her body, flicking behind her as she lay on her side. It squeezed out of the top of her shorts, reaching its full length, ending at her upper back. More hair continued to grow across her back and torso, prompting her to roll over in discomfort.
"Ugh... Why am I feeling so hot— Eep! Ow, what the fuck..." She groaned as she rolled over on her tail, jolting up as she put her weight on it against the bed.
Hannah tossed her book aside and turned around. Her eyes went wide when she saw her new appendage. It waved around, perfectly following her control, forming a small loop at the top. Leading down into her shorts was an increasingly dense forest of hairs, which she could now feel travelling along her legs.
"O-oh god... Don't freak out, don't freak out, don't freak out!" She tried to reassure herself yelling loud enough so that Theo could hear from downstairs. She tucked in her legs to get a good view of her tail.
The hairs continued to flow around her stomach and then down her legs, nestling in between her thighs and making her shorts feel a little itchy. Hannah's body was also a little shorter than before, losing around two inches of height to adjust to her new form. She continued to play with her tail, mesmerized as she flicked it back and forth, not paying attention to her now completely hair covered legs.
"Uff... What now?" Hannah whined, turning her gaze to her legs with a tiny gasp as she saw how much they've changed. She ran her hands through the hairs, noticing that her arms were becoming covered with them too.
Hannah's most pressing change however, was her feet. Underneath her socks, the fur spread up the top of her foot and stopped at her toes, leaving the sole hairless. Her big toes on each foot began to shift lower on her foot, ending up at the side to be primed for gripping. The rest of her toes became a little longer and more finger-like, stretching and wriggling in her socks. Hannah could feel this all happening, but was nervous to remove her socks. Upon doing so she nearly shouted once more, not expecting her feet to look and feel this strange. She grabbed at the bed to test them out, then brought them up to her face to inspect them closer.
"Ew... I smell like a zoo enclosure..." Hannah recoiled as she caught a whiff of her new feet, putting them back down.
The hairs along the rest of her body now covered her chest, coating her petite breasts as it flowed up her neck and to her face. As it did, a few thoughts circled in her panicked mind. This had to be the work of Theo... He was the only one home, and was obviously hiding something earlier. She hopped off her bed, almost falling down as she stumbled on her new feet.
"THEEEEOOOO!" She shouted, her voice augmented a little as her face stretched out. Her nose flattened against her face, pushing out her mouth a little to look more monkey-like. In addition to this, her final change came with her ears becoming rounder and sticking out more, now cutely peeking through her hair.
Hannah marched downstairs with an angry expression on her face. She knocked on Theo's door, which he opened immediately, surprising her.
"Oh my... Haha! Look at you! This is too cool..." Theo sighed, laughing in his sister's face.
"S-shut up, you ass! How did you turn me into this... weird monkey thing?" Hannah whined.
"Secret. Now go take a shower, Connor is coming over in a few minutes, and I can't have you stinking up the place." Theo said as he walked past her dismissively.
"W-what? I just took one like two hours ago!" She groaned, following him to try and get his attention.
The two of them were arguing right by the front door, and a knock sounded from the other side when Hannah was standing right in front of it.
"Oh? Looks like he's early. Can you let him in, banana breath?" He teased, watching Hannah grumble as she protested, then nervously opened the door...
