Chapter 3: Rising Action
Sophie chartered a course through the streets to her sister’s house which was only three blocks away from the lab.
Though her physical changes were not completed, she feared what she may become if she stayed in the lab. So, with her heart pounding against her ribcage, Sophie pressed onward, despite the increasing heaviness weighing down her strides. She hoped to find sanctuary at a place where she knew someone loved her unconditionally — Jenny’s home.
Jenny, Sophie’s younger sibling, lived quietly and contentedly spending evenings watching movies and reading books.
When Sophie arrived at Jenny's door, Jenny could hear her sister’s voice greet her and Jenny threw open the door with a big embrace before even realising that Sophie was now looking different and there was a lot more to hug.
Jenny looked stunned as she pulled back and it was then that her stunned look was replaced by a look of fear as she felt a strange feeling course through her body. Sophie realised then that she had passed the growth virus onto her sister.
A surge of guilt washed over Sophie but she tried to remain composed as she noticed that Jenny’s chest was starting to look bigger.
"Jenny," Sophie asked nervously, "do you feel alright?"
Jenny shook her head, her eyes darting between Sophie and her suddenly swollen cleavage. "Uh, I feel like something is happening to me," she mumbled, her voice quivering.
Sophie closed her eyes and sighed heavily. "I didn't mean to pass anything onto you," she admitted.
“Pass what on?”, Jenny exclaimed as she started to feel her rear growing causing her skirt to inch up slowly. “What is happening to me Sophie? What happened to you?!”, Jenny yelled, her eyes darting between Sophie and her rapidly expanding chest. “How did this happen?”
Sophie ran her hand through her tangled hair, her eyes brimming with worry. "I don't know exactly," she confessed, "but I think I might have caught something from the lab. It's making me grow, and it appears to be spreading to you."
Jenny paled, her gaze darting between Sophie and her increasingly ample bosom. "Spreading? To me?" she gasped, her voice filled with alarm.
"I can feel myself growing, Sophie!"
Sophie nodded, her grip tightening around Jenny's trembling hands. "I know," she whispered reassuringly. "I'm sorry, Jenny. I never meant for this to happen to you."
With every passing moment, Jenny felt the change taking root within her. Her breathing accelerated, and a palpable tension coursed through her veins.
Jenny's eyes darted between Sophie and her blossoming curves, her gaze locked on the swelling mounds that protruded from beneath her blouse. An inexplicable heat surged through her limbs, accompanied by a strange sensation of fullness, as if a thousand butterflies were fluttering inside her abdomen.
"I feel..." Jenny stammered with shock, “…amazing. I feel stronger, sexier. I’m loving these changes. When will they stop?”. Just as Jenny finished her question, a final powerful surge of growth rocked her being.
Jenny stumbled back into the wall as her body continued to quickly morph.
Sophie watched with disbelief and jealousy as her sister's silhouette began to contort and stretch into a more towering figure. The walls vibrated with every thumping heartbeat that emanated from Jenny's expanding form.
"This….this…" Jenny struggled to form coherent sentences, her throat tightening with adrenaline pumping through her veins, "…feels incredible!"
Jenny’s frame once more inched taller as her breasts continued to balloon testing the confines of her bra and now skin-tight blouse.
“Oooohhh,” Jenny moaned, “I love this,” she said, running her hands up and down her now thickening thighs as her hips widened seductively.
Her face became more beautiful as mirroring her improved body in other ways.
She reached behind her back and deftly undid her bra releasing twin E-cup melons that seemed to defy gravity but were forcing large gaps between the buttons in her silky blouse.
Jenny arched her back causing a button to ping across the hallway they were standing in and almost hit Sophie.
Sophie was awestruck as Jenny now towered over her, and as Jenny's body changed, the hallway seemed to shrink around them. Jenny's breasts formed large round mounds, seeming to be filled with helium, and her hips curved wider than any hourglass. Her skirt rose higher with each second that passed revealing long shapely legs leading up to a waist that seemed to disappear in the shadow of a massive rack that hung above.
Her arms widened and strong as she placed her hands on her hips, leaning back into the wall to show off her figure. Sophie couldn't believe how beautiful her sister had become. She was statuesque, voluptuous, and radiating confidence. She wondered how the virus could such powerful and immediate effects.
Jenny stepped forward and moved quickly towards her bedroom with a mischievous grin as she hurried to change clothes.
She wanted to wear something that would better showcase her curvaceous new figure. Sophie followed closely behind, still dumbfounded by the rapid and dramatic transformation that had overtaken her sister.
As Jenny slipped into a tiny black dress on her much larger body, she cast a sultry glance over her shoulder, a knowing smirk playing on her lips. E-cup breasts were pushing well out of the top of the dress and her cleavage resembled a canyon.
"Sophie," she purred, "I must say, I rather enjoyed this transformation."
Sophie gaped, her mouth hanging open as she watched Jenny saunter confidently towards the front door.
“Sophie, let’s hit the town”, Jenny explored, “I ready to show this body off while it lasts!”
Sophie didn’t have the heart to say that she thought the changes to their bodies could be permanent and quickly followed her out the door.
