To her increasing alarm and disorientation, Mary began to change much more rapidly than the tiny spurts of change she had experienced so far. Her disproportionately long arms and barreled out torso were just the start, as another rush of change ached through her with great speed.
The transformations became even more intense, rippling over and dehumanizing Mary’s naked flesh with ferocious speed. As she stood in front of her bedroom mirror, Mary was completely helpless as she was paralyzed with pain and dizziness. She watched with horror as her still considerable breasts deflated into her expanding chest, her entire torso inflating like a balloon the entire time with both roundness and musculature. As this was happening, her body was becoming expansively large, as it doubled in size to twelve feet tall and kept gaining mass.
Pain in her face made Mary wince and whimper in dismay, as she knew her muzzle was beginning to press outward. Indeed, Mary’s mouth began to protrude into a snout, as it grew longer and more squared. Her nose forced itself upward to almost the top of her forehead and a tiny slope of a head crest developed. Mary’s growing tongue dangled from her mouth panting, coated with thick saliva, as her teeth turned into round pegs designed for tearing off and grinding up plants.
Then her neck was suddenly stretching longer, and longer, and Mary barely had time to look down at her increased perspective before it rose up further, her neck forcing her gaze up higher and higher until her head bumped the roof. Mary could only gaze down stupidly at the mirror showing the massively sized inhuman creature staring back at the slits that were now her pupils. With another sudden rush Mary’s spine crackled and stretched, as her tiny tail shot out and thickened tremendously, growing long and flexible.
“NO! NO! STOP!” Mary screamed in shock, her voice low and reverberating, as she actually felt herself going from a bipedal humanoid to a quadruped stance. Her back snapped suddenly, despite her protest, and she roared in anguish as she pitched forward onto all fours, her arms as thick as her back legs and her hands rapidly plumping into imprecise four-digit feet. Mary cried in dismay, tears welling at the edges of her eyes, as she suffered the loss of her hands as her body continued to grow.
In no time the changing Brachiosaurus woman filled her bedroom, audibly stretching and expanding as her neck craned out longer and her body grew to incredible proportions. She was trapped in her room, becoming more and more dinosaurian by the second. Her skin felt leathery, like it was drying up and cracking, and Mary sobbed softly in disbelief. As she turned her neck around, with some difficulty given her constraining situation, and saw that a soft blue hide was overtaking her still pink flesh with bumpy patterns like a lizard.
She grew bigger still, the floor creaking from her terrific weight and her room turned over into a complete mess. Mary was forced to lie down, and her body filled the entire bedroom and her neck shot out two doors down. She heard the ceiling start to crack and her mobility was constricted painfully as she grew. And then, just like that, the process stopped, leaving her pulse beating insanely and her mouth panting for something wet.
Mary arched her neck down the hallway, and found she could easily reach the bathroom. She snaked her neck around the doorframe and gasped deeply, feeling her body swell with air in the other room, as a huge blue Brachiosaurus snout greeted her gaze in the bathroom mirror with an absolutely shocked expression. She huffed deeply, her warm breath fogging the mirror from the top of her nasal openings on her skull, and she gulped, feeling her saliva travel down her long powerful throat in a couple seconds.
There was no human left except her mind. And to Mary’s horror, she felt the changes welling up inside of her, getting ready for the last big spurt that would swell her up into a full-sized adult Brachiosaurus. She was now past worrying about her boyfriend and his parents. Her world was consumed by a panicked need to go back to her human shape. But how?! She had gone too far, too fast! How could she possibly get to the vials?
She hung her head and rested it on the counter, her enormous snout dangling over the sink. What had she done to herself? And then, her large yellow eyes spotted the human female vial, sitting at the edge of the sink where she had left it earlier before her transformation had kicked into full swing. Hope gripped her stomach and she gasped sharply in relief!
If she could reach the vial and uncork it, she could reverse this whole mess and nobody would need to be the wiser!
