Sister goddess time

    by: Neon Author IconMail Icon
After a long afternoon of sneaking around and finding the right opportunity to steal dozens of boxes worth of growth pills, Molly and Tim made their way back home.

"We did it!" Molly said excitedly, her eyes wide with anticipation as she clutched on to the boxes of pills with a giant grip. "With this many pills, I can definitely grow as big as I want!"

Tim couldn't wait to see how far his new giantess sister would take this. All he wanted now was to see her reach goddess-like proportions.
Molly led her little brother into her room, excited to start the growth process. She placed the box full of pill bottles on her bed and began to count out the doses one by one.

"Alright, little bro," she said with a smile. "I'm going to take three pills now to make sure I keep growing. You can watch, but don't touch! These pills are mine."

She reached into the box and picked out three bottles, then swallowed the pills with a glass of water on her nightstand.Tim watched as his sister began to swallow the pills, eager to see her transformation and how big she would actually grow. Molly stood up from her bed and began to stretch her giant body, feeling everything grow. Her breasts were becoming impossibly large as her hips grew wider and wider.

Molly looked down at her little brother and saw the expression on his face as he watched her go through another growth spurt. His eyes were wide with disbelief as he took in every inch of his new giantess sister's incredible curves.Molly watched as her little brother's gaze traveled up and down her new giantess body, taking in every inch of her impossible curves. She loved seeing the look of lust and desire in his eyes as he took in every inch of her new figure.

"So, little bro," Molly whispered seductively, letting her breast hang out as she continued to stretch. "What do you think of me now?"

Tim was taken back by his sister's boldness, and couldn't help but feel both turned on and a little intimidated as he looked up at his giantess goddess.I'd say you're doing a pretty good job," he said with a flirtatious smile. "Those pills are making you grow faster than I expected. But as your god, I think you need to go even bigger. How about five more pills?"

Molly didn't need much convincing. She reached into her box and swallowed another five pills, then continued to stretch and work the pills through her system. Soon, her hips were wider than her shoulders and her massive breasts nearly touched the floor as they pressed the top of her shirt out to its limits.Tim was surprised by how quickly Molly was growing, and wanted to see his sister reach towering heights. "Sister," he said with a grin, "why don't you swallow the whole bottle?"

Molly knew that her little brother would be satisfied if she reached 50ft tall, so she took one final deep breath and swallowed the rest of the pills. The growth process was almost instant, with Molly doubling in size, then tripling, then quadrupling, until she was finally reaching 50ft tall.
Tim stared in awe as his sister continued to grow. "S-sister, you're huge!"

Molly turned to look down at her little brother and chuckled. "I certainly am."

She had reached the height Tim had wanted her to, but Molly figured she could go even bigger. After all, being a giantess was more than just about reaching a certain height, it was about feeling huge, about reaching those god-like proportions.

"I think I'll take a few more pills," Molly said with a grin as she reached for the bottle. "Just one or two more."Molly burst through the walls of her room and out of the house in one quick leap, her new god-like body sending debris into the air as she made her way outside.

She took in a deep breath and smiled, feeling the power coursing through her body as she realized how immense her size had become. With a twirl of her new hips, Molly sent the neighborhood into a panic as the ground started to rumble under her giant feet.
