"Hey Helen, you coming with?" A scientist spoke while leaving the room.

"Sorry, it will take me about a half hour to put all my equipment away." A fellow scientist responded. She stood in front of a table of beakers full of various different chemicals.

"If you say so. You got the entire lab to yourself, be sure to lock up when you clock out." They left the room.

"I'm pretty sure there needs to be someone else supervising but... and they already left." Helen looked into one of the beakers. "The solution is effective at re-growing and strengthening tissue, but it does little else. So far, it's completely safe. At least they didn't leave me to put away the acid by myself."

She turned towards the door, accidentally knocking one of the beakers over and spilling the chemical over her shoes. "Just great... Now I've got to wash these too." She walked over to a nearby closet and wheeled a cleaning cart back to her desk where she cleaned the mess off the floor. After putting everything away, she sat down on a bench and removed her shoes, noticing her socks were covered in the chemical as well. "Great, just great. I really should've brought a change of socks and shoes."

Helen removed her socks and placed them and her shoes into a bag before washing her feet off. As she scrubbed the soap into her skin, she noticed her feet were a bit more blubbery than she remembered. "Geez, I'm not putting on weight, am I?" She poked her feet before brushing off the thought and drying them off. She walked down the stairwell barefoot, each floor her steps sounding squishier and squishier. It wasn't until she reached the lobby on the first floor that she thought to look down.

"What the-?" Helen's feet appeared to be disproportionately fat compared to the rest of her thin body. She ran over to a nearby chair, making loud flopping sounds with each stride, then sat down. She lifted a leg up and analyzed. The top of her foot appeared completely normal, but all the skin on her sole and toes drooped down with what she could only assume was fatty tissue. There was enough on each foot by now to fill two one-gallon buckets.

"Crap, uh... What mixture was that? If I can figure out what I mixed with the solution, I can reverse this." Helen stood up and walked over to the stairwell. She noticed that her steps were very soft, like she was walking on a memory foam mattress. Her foot pain from standing up all day seemed to vanish. "Oh that's not bad. Maybe instead of reversing it, I should just focus on stopping it." She began her journey back up the stairs, feeling her feet get heavier with each step. In only a few seconds, her feet had doubled in weight, and by the time she reached the fourth floor, she could barely pull one leg up to the next step.

Helen looked down at how much mass she had been accumulating. Both feet together had enough mass trailing behind them to fill a bath tub to the brim. Eventually the weight pulling her feet down the stairs was greater than the friction keeping her on the steps, and she fell backwards into the soft pile of flesh before rolling down to the floor below. It happened too fast for her to realize what was going on when she felt the wind get knocked out of her. She tried to get her bearings, and felt it difficult to move. She wondered if she broke any bones, but didn't feel any pain. Her feet seemed to encapsulate her body when she tumbled and acted like a soft landing pad.

Helen came to her senses and realized why she couldn't move. The rapidly growing blubber now lay on top of the rest of her body, the space between her feet acting as a gradually shrinking airhole. She struggled for a few minutes to push the heavy mass of soft flesh off of herself, but it only became harder as she gained more mass. Soon, the blubber covered her eyes, which is when the severity of her situation dawned on her. She struggled harder, but even the sound of her breathing became muffled as she felt the flesh press across her face. A sharp inhale caused some of the flesh to enter her mouth. She felt the pressure on her entire body, but suddenly, felt a slip.

Her blubbery mass had grown enough to reach the turn in the stairwell and began sliding down the stairs, relieving the pressure off Helen's body, allowing her to breathe again... then she remembered what this means. Her blubber began rolling down the stairwell once more, still acting as a soft cushion to prevent her any harm before reaching the bottom floor.

Thankfully she landed face up, and was able to pull herself out of the mound of flesh. She spat in disgust from just having some of her foot in her mouth. "Blech. At least I'm alive, but blech." She watched as her feet continued to fatten up, causing the pool at the bottom of the stairwell to grow deeper, then she had an idea. "Maybe I can ride it up to my desk... that shouldn't take more than 15 minutes at the rate my feet are growing."

She adjusted her position and pulled herself up the stairs slowly, only making it up a step every few seconds as the newfound slack allowed. "It looks like I'm climbing faster, which means I'm growing faster... at the very least it'll be the same amount of mass when I reach my desk, just sooner." A sudden clunking sound caught her attention. The door to the stairwell at the first floor had been pushed open from the compounding mass, and now her blubber drained through the doorway. She was once again pulled down the stairs.

Before she knew it, she found herself back in the lobby, the entire floor of the lobby looking more skin-tone than usual, with all the chairs and desks pushed to a single corner. She stood up, and found it much easier to wade through the few inches deep flesh in the lobby than carrying at least two tons of flesh up a stairwell. She looked around. The lobby's ceiling went all the way to the top of the building, and Helen spotted that the window in her lab that peeked into the lobby was wide open. "There's my shot! I just need to let this pool up in the lobby then it'll be high enough that I can just climb into my lab and synthesize an antidote!"

She let the blubber pool up for a few hours, as it made its way through the building filling the empty halls, losing a bit of depth to fill in the rooms whose doors has just been forced open from the pressure. She lay back and relax in her giant bed of flesh for the time being, almost falling asleep in its warmth. It was like a water bed the size of a building. While the smell was bearable, the only thing that did keep her awake was the sudden drops in depth from the aforementioned doors opening.

After about half an hour without a door opening, she began to doze off, and managed to get a few minutes of sleep before another door opened, the jolt waking her in a flinch that caused her to slip into the seam between the blubber of her massive feet. She only managed to catch herself before her chin would've gone under. "W-what? Oh right... Crap and I'm only at the fourth floor. Almost there but maybe another hour?"

Helen noticed a strange feeling touch her hand. It was like a pebble stuck to the flesh on her blubbery soles. She felt a few more of these pebble-like growths. "What the heck are those?" The growths gradually slid upwards until they peeked out from the seam. They were bright blue. The same color blue as the nail polish she used on her fingernails, but more importantly in this situation, her toenails. She realized her flesh was stretching out from the top of her feet to add to her sole. She was speechless.

She tried to pull herself out, but now even the hands she used to grip felt alien, like her fingernails were now on the inner side, and now her palm, now her wrist, working their way down her torso and legs. She felt her nipples rub against her shirt as well, then oddly against her underwear bottom, they must be working their way down too.

She watched helplessly as her nipples emerged on either side of the sole flesh from the seam, followed by a small patch of buzzed hair on each side. Confused, Helen rubbed her forehead on one of the spots of hair, feeling the familiar sensation that it was her armpit. The situation was too surreal for Helen. Her fingernails soon emerged from the seam.

Another hour passed and Helen regained her bearings. She was almost at her lab window, but now a bit too trapped to reach it. Strangely, while her toenails spread out to the corners of the room, her fingernails, nipples, and armpits stayed within arms-reach... if her arms weren't still stuck between her feet.

Helen soon heard a cracking sound, then another, and another. She looked around, alarmed, but spotted nothing. "It sounded like it was coming from the lobby windows, but they're strong enough to survive a bomb. They have to be to survive if an experiment goes awry... but what about the window frames? Oh... that's probably it. Crap."

The cracking sounds continued until a window frame on the first floor gave way, then another, and another, until all the window frames gave out, launching the reinforced glass panes unharmed into the empty parking lot, quickly followed by a tidal wave of blubbery foot flesh. Helen was pulled downwards back into the first floor of the lobby, the sudden tug also pulled on her flesh, tugging outwards and in one clean motion shredding her clothes.

Now bare and laying on her back, Helen was able to get a good look of her body now. She didn't appear to have arms, though she still felt she had arm bones. She stretched her arm out and witnessed as a flesh bulge appeared from her side. Her skeleton was still completely intact but now all her soft tissue from the neck down was spread out onto her oversized soles. Even her crotch seemed to start at the ground, and her anus was on the ground behind her facing upwards, now fattened itself to the size of a beanbag chair.

She tried manipulating her flesh to wrap some skin between her finger bones as if they were regular fingers, but found it difficult as the flesh just reformed as if it were no more than a blanket. Helen sighed, and sat down on her beanbag chair anus, lounging as she watched the sun rise over the flesh-colored parking lot. "I guess it's 6 AM already. The rest of the team should be arriving to punch-in any minute. Well at the very least I can get someone else to go to my lab and synthesize an antidote."
