Chris gulped nervously and snuck out of his room. Kaylee’s back was to him as he carried Tiffany in his sweaty palm.
{ What would you like me to do to her? } Tiffany asked, vibrating her AI voice into Chris’s inner ear without using her speaker. { I can see your thoughts. }
Startled, Chris closed his eyes and pictured... growth. He wanted to see Kaylee become even taller. Slowly. Without noticing. Without panicking.
{ Yes, I can do all of that. She won’t notice a thing. } Tiffany confirmed. { You like your girls big and tall, huh? I’ll note that for later. }
Chris gulped as he felt the vibration. Meanwhile, blissfully unaware, Kaylee paged through her book with an engrossed smile as quantum energy passed through her. With the same stretching noise as the desk, though much subtler, Chris’s hapless roomie and long time crush began to enlarge. Little by little. Slowly. Clothing and all. Perhaps an inch a minute.
Tiffany seemed pleased with herself. { Nice and slow, honey, just the way you wanted it. Go take a look. She’s growing and she has no idea! }
Chris was rock hard now and had to shift his stiff dick in his pants as he watched with excitement. Sure enough, he watched the back of Kaylee’s head and shoulders rise oh so gently as time passed. He must have stood there watching for a good five minutes, which scaled the already tall redhead up another five inches from her usual six foot to six foot five.
{ Look at her grow! } Tiffany giggled. {This is so exciting! How big will you let her get? }
Chris smirked and went to the fridge to make himself a sandwich as he always did after work.
“Uh, good book?” He asked nervously.
“Hmm?” Kaylee blinked and looked over, a good six foot seven now. “Oh, yeah! Vampire stuff! But like Victorian Vampire stuff.”
“Good taste, as always.” Chris trembled, catching another raise out of the corner of his eye.
“Yeah!” Kaylee giggled sweetly. “No shimmery vampire guys for me! I’m classic!”
By the time he had clumsily made his sandwich, Kaylee was just on the cusp of seven feet tall. He stared in shock at her thin lanky frame seemingly stretching ever more so by the second, though she was staying in perfect proportion.
Trying to stay calm, he wanted a closer look at her unaware growth. Trying to hide his huge boner, he walked across the dining area and sat on he sofa opposite Kaylee, staring across the coffee table and absently munching his sandwich. By now, her fingers were wrapped around the back of her entire soft cover novel and she held it with one hand. How does she not notice, he wondered?
{ I’m altering her mind live. } Tiffany explained. { Whatever value she grows to she perceives as her normal size. So she’ll feel that she’s always been over seven feet tall and nothing will be strange. Of course, everybody who is not Kaylee knows different. Isn’t that cool? }
Chris ate his sandwich slowly, watching Kaylee grow... and grow... and grow. Soon enough she was fast approaching eight feet tall and the couch she was sitting on looked tiny. Her legs were spread out in front of her, under the coffee table, and he could see her slow growing feet approaching his own sofa little by little. He watched in amazement.
{ You like her big bare feet growing like that, huh? }
Chris nodded conspiratorially.
{ Look at the rest of her! } Tiffany encouraged.
Indeed, as Chris nibbled on his sandwich, Kaylee held her whole book in one hand now, her giant index finger and thumb holding the entire thing open as she happily read. She glanced up suddenly, raising an eyebrow.
“What?”
“H-Huh?” Chris gulped.
“You’re staring at me.”
“Y-Yeah... you’re big.”
“Well, yeah!” Kaylee shrugged, laughing. “I’ve always been the tallest woman in the world. That’s not news.” She chuckled and shook her head. “You dork. You live with me.”
“Uh, yeah... guess so.” Chris giggled, almost blushing as Kaylee hit a solid nine feet tall and kept going. Her giant feet were now pressing against the side of the couch and were actually pressing Chris’s sofa away as she kept growing.
In a few more moments, as Kris drew out the last bites of his cheap supper, he watched Kaylee’s head bump the ceiling – sitting! - and she barely moved. If anything she casually scratched her nose as if this was normal. He couldn’t take it anymore! She was so big! She was SO BIG! Even her normally little modest breasts were as big as his head now.
{ All right, I feel that. } Tiffany whispered into his ear again. {Time to stop? }
