“You know, I really shouldn’t be letting you do this.” Professor Spivak stopped at the doorframe, hesitant on leaving for the night. “For all I know, the moment I exit this place, you call over a bunch of youngsters and play ‘spin the bottle’ with the centrifuge.”
Although his tone was partially sarcastic, party games using the lab equipment was a serious concern at the Biology department. He recalled the incident of 2019 where a student managed to swipe one of the keys and invited half the frat houses into the building. All classes inside the building had to be canceled for a week as the janitorial staff attempted to undo the damage.
A blue haired girl wearing a lab coat sat writing alone in the center of the room, her hand darting across the notebook. “Oh, I can’t possibly allow such a thing.” Tabitha said without taking her eyes off the page “I’ve only got so much time to work and the Preserver Drug isn’t going to crack itself.” The sophomore biologist blindly searched the table for her coffee with her non-writing hand, grabbed what felt like a cup and took a sip from it.
Professor Spivak gave one last sigh before giving up. From his experience, the only way to separate Tabitha from her work is with a fire. He closed the lab door and briskly walked down the hallway, whistling tunes familiar only to him.
Thought he’d never leave. Tabitha put down her pen and checked her phone for the time. 10:03 pm. She should have more than enough time to finish recording this data tonight and move on to human trials within the week. It’s crunch time at the brilliance factory Tabi, and you better be the employee of the god damn month. She took another sip of her coffee, a rush of adrenaline went through her followed by an overpowering sense of exhaustion. Oh, who am I kidding? I’d much rather be piss-shit wrecked right now.
Were that she was able to, Tabitha would not hesitate to call ‘a bunch of youngsters’ to the lab and drink tequila shots out of the test tubes. However, as she stared at her phone’s contact list, it contained a single entry titled “Mom”. The fatigued girl considered inviting her mother to the Monday night drunken science party before her phone notified her it was out of battery and abruptly shut down.

After everything was recorded, Tabitha chugged down the last of her coffee and slumped backwards into her rotating office chair. She kicked both her feet onto the table, displaying her bare legs under a short summer dress. Huh. She realized. Why am I acting like I’m not the only person in this building? She tossed the empty coffee cup towards her back, not caring where it landed. She also realized her it was too warm for her lab coat, so she got out of it. Still feeling uncomfortable, she reached around to her back and loosened her bra hooks. As if being rejected by her chest, the cumbersome garment slid off into her dress before being grabbed and tossed away.
Basking in the freedom from her public attire, Tabitha stood up to stretch and pace around the room. She then turned to look at the clock. 12:17 am. She sat back into her chair and closed her eyes, fantasizing about the days ahead. She could visualize the inevitable headlines. Tabitha Wallis and her revolutionary Preserver Drug, 19 year old female prodigy trumps the bigwig professionals with her answer to the superbug crisis.
Excitement rushed back to Tabitha as she searched the cabinets to find the bottle filled with her miracle fluid. Created through years of tireless research, the Preserver Drug was a mixture of artificial proteins meant to be ingested by the user. It’s designed to target cells foreign to the host and change them into a compressed, dormant state. Theoretically, it should be the world’s most effective antibiotic and yet able to preserve the human microbiome. Giggling in pride, she played around with the bottle like an infant’s toy, shaking it and putting it against her lips.
And the only thing that stands in my way is the… stupid humans and their stupid trials. Tabitha noticed she was unconsciously unscrewing the cap off the bottle. She raised the open container to her face and wafted the air towards her nose. She was hit with the familiar smell of the ethanol solvent. Well, that’s one way to get hammered I guess. She realized. Come to think of it, this should count as human trials.
Tabitha impulsively chugged the entire bottle of the Preserver Drug, it tasted like a gasoline flavored cocktail, and went down as smoothly as bag of gravel. She let out a small hiccup after drinking it, and began juvenilely giggling. “None of you bitches are going to tell Spivak” She told the empty room. She gleefully stretched arms and relaxed them. Her head tilted to the side as she let out a joyful sigh. This was definitely a huge mistake.
As if to answer her question, Tabitha heard a faint sizzling sound coming from her hands. She immediately raised her arms flinched at what she saw.
Steam-like wisps of gas were diffusing from her slender fingers. Tabitha could only sit in awe as the steaming parts of her spread down her hands, onto her wrists and forearms. She tried to touch her simmering skin but by that time she could no longer feel her fingers. When she tried to move them, she noticed that their tips have seemingly disappeared, as if evaporated into the steam. She could even feel the water condensing on her face, forming a moist layer of water.
Oh, no. No fucking way. Tabitha’s fingers, along with her hands, began rapidly evaporating away, leaving two stumps at her wrist which continued to move through her arms. She stood up and paced around the room, both panicking and captivated by such an unexpected effect. Her stumps wore past her elbows, finally stopping after a full minute has passed. Tabitha tilted her neck to her side to observe the aftermath. It appeared that the Preserver Drug consumed both her arms and most of her shoulders. Surprisingly, the entire process was painless.
This is not happening, how is this happening? Tabitha anxiously searched in her mind for a cause. Before she drank her invention, it had only been tested on lab mice, none of which have had their limbs evaporated. She then remembered the second part to the invention. Wait, my notes! There’s got to be something in there.
Tabitha walked back to her table, attempting to keep balance in her new form. Before she arrived at her notes, she realized her dress had been soaked through by all the steam. Water was dripping from the edge of the skirt and her bare nipples were pressed against the translucent fabric adhered tightly to her torso. Can’t exactly read my notes like this considering the water will ruin them. She thought. Fuck it, it’s not like anyone is going to walk in here.
Tabitha attempted to move what remains of her upper limbs to no avail. She did not have any opposable stubs she can use. Switching to the alternative, she kicked off her shoes. She tried to pull off her socks with her toes, but lacked the dexterity to do so gracefully. After a minute of fumbling around on her chair, she managed to remove both her socks. She sat on the floor in a butterfly pose, and raised her foot to her sleeves. She tried reaching for her dress with her toes but where nowhere near flexible enough. Giving up, she stood up to look for something to hook her dress onto. Having found her target, the armless girl pressed herself against the cabinet, hooking one of the dress’s arm holes onto the handle. She tugged her body backwards, sliding her torso out of the dress.
Without a bra, Tabitha’s breasts were on the full display. She instinctively tried to cover herself before remembering she had no arms. Her light green underwear was also visible to room, stretched tightly by her curvy hips and thighs. Feeling a surge of cold air slam into her skin, her nipples hardened and she began immediately regretting her decision to remove her dress. However, considering her poor flexibility, she knows she won’t be able to put it back on any time soon.
Tabitha jumped onto the table and began turning through pages of the notebook with her toes. It took a while, but she managed to get to the page she needed. Rereading her jot notes for the fiftieth time, the error then seemed obvious. Her Preserver Drug was only modified to not work on mice cells; pretty much everything else was fair game. She continued to search through her notes. Undoing the effects of the Drug was easy; the cells were simply in a dormant, dry state. She simply needed the right chemical messengers to reactivate them.
Before she could finish reviewing the formula, Tabitha heard the familiar sound of steam coming from her toes. No, not now! Need to make the Reverse Formula. Knowing she had to get her equipment before her legs disappear, she quickly scooted across the table on her buttocks. Her materials were conveniently located in the cabinet at the end of the long table. Tabitha used the remains of her feet to open the cabinet as they disappeared up to her ankles. She then sandwiched the rack filled with her materials between her calves and used all her strength to swing her legs towards the other side. Setting the rack onto the table, her forelegs have already disappeared halfway. As her grip loosened, the rack of chemicals fell onto the table, The glassware was shaken, but not broken.
Tabitha then turned back to the cabinet, a hot plate stood on the upper shelves. She knew she is going to need that for the last step. She tried reaching for it with her knees, but managed to barely touch it before her legs became too short. Shit shit shit! She tried to prop herself up with her right thigh to extend her reach, but her shrinking legs always remained one step ahead. Finally, her legs disappeared up to her pelvis, leaving the limbless girl squirming helplessly on the table.
After coming to the conclusion that it was hopeless, Tabitha laid on her back. The proteins needed to reverse the effects of the Preserver Drug require being at a minimum of 35 degrees Celsius in order to be properly activated. She looked down at her nearly naked body, her underwear soaked just like her dress. Guess I’ll have to wait until morning. She looked at the clock again. 1:05 am. Cursing the caffeine in her system, she prepares for a boring and sleepless night.
It’s going to be humiliating when they find me like this, isn’t it. They probably won’t even bother restoring me considering the field day they’ll have studying me. Tabitha wiggled her torso a bit, trying to see if she can position herself to seem more professional. They’ll obviously cancel human trials as well, perhaps even my entire project. Come to think of it, they never even took me seriously in the first place. Spivak probably thinks I’m sniffing glue with my non-existent youngster friends.
Maybe enough of me will disappear so I don’t have to deal with this mess. What if I end up as some sort of… dried up person-jerky, a lump of Instant-Tabi. Tabitha deeply pondered her predicament. Jesus dick-piston Christ, forget my career; I’m seriously fucked right now. Those chalk sniffing, posers in lab coats they call professors aren’t going to read my notes and cure me that’s for certain. They’ll write me off as a fatality most likely. I’ll spend the rest of my life in a biohazard bin along with a bunch of fetuses and virus cum.
It dawned on her that she drank her drug mainly out of boredom. Stupid Tabi. Stupid! STUPID! Just had to drink the untested science fluid didn’t you. Congratulations on your well-earned Darwin award you smartass Alice-in-wonderland shit-chugging alcoholic. Before Tabitha could reach a textbook panic attack, another thought sparked in her mind. Wait, there’s a way out you well-educated moron and you know it. She lifted her head to look at the hotplate, sitting so close to her, yet virtually unreachable. You’re a freaking prodigy you pile of ass. Just set the hot plate problem in the back of your mind. Work out what you can and let your genius brain do the work.
Having calmed down, Tabitha once again tried squirming, but this time driven by her signature ambition. Yeah. You can do this! With calculated movements, she managed to rock back and forth, building up momentum by swinging her hips. Finally, she managed to flip herself onto her front, nearly falling off the edge of the table. One of her breasts pressed up against the surface, the other dangled past the edge, pulling her down towards certain failure. She quickly squirmed back to the center of the table, and began inching herself towards the chemical rack. Let’s just hope I don’t end up tasting most of these regents.
Having slithered her way to the rack, Tabitha started off by digging into the rubber stoppers with her teeth, bending her neck backwards to remove them from the beakers. One by one, she smelled the industrial odors of the chemicals. She carefully bit whatever test tube or utensil she needed, and shifted her weight so that her head aligns with the next component. The process was arduous and required intricate movements of her lips, jaw, and tongue, and yet must be repeated endlessly as she creates what she calls the Reverse Formula.
That looks like about 20 milligrams of crystallized iodine, fuck it, in you go. After spitting the measuring spoon off the table, Tabitha turned to the eye dropper, grabbing it with her lips. Look at this, I’m on fire. I’ve got no limbs and I’m still a pro at this. She pressed her tongue against the rubber bulb until she drew a sample of dissolved glycine. Fire… what if I start a fire? Nah, that’s not going to heat up the formula so much as it would vaporize the formula and burn down the lab with a helpless idiot inside.
After several hours of tireless work, Tabitha corked the large test tube which contained the penultimate stage of her reverse solution, pushing her nose against the rubber stopper to secure it. She drooped her head in exhaustion. Most of her remaining muscles are painfully sore. She knew that in order for the Reverse Formula to restore her body, she would need to be well hydrated.
Switching back to work mode, Tabitha inched her head towards the bottle of distilled water at the far side of the rack. As she was about the reach the bottle, her chest pushed the rack away from her. She felt the cold steel and glass surfaces slide against her breasts. She shuddered involuntarily, knocking off a beaker with her chin. Oops, shit. The clumsy scientist looked at the beaker she knocked over, its contents spilling onto surface below her chest. Oh, it’s my concentrated biomass. She realized. Wait, this isn’t good. Not this shit!
Before she could squirm away from the biohazardous fluid, the spillage was starting to be absorbed by Tabitha’s breasts. Slowly, the pool of concentrated biomass shrank as substance diffused through her skin. She frantically tried to inch back, but the substance has already activated within her body.
Tabitha felt a numb and tingling sensation. She could feel her heart race as her breasts began to slowly push her away from the table surface as they inflated like water baloons. Gradually, her breasts grew to the size of oranges, then cantalopes not soon after. Meanwhile, her nipples and areolas also swelled disproportionately to her breasts. By the time her breasts were the shape of basketballs and had the weight of watermelons, she was resting only on her grapefruit-sized areolas. Tabitha then noticed her pelvis was no longer touched the table surface and was instead raised in the air invitingly, balanced up by the massive weight of her breasts. Her lower cheeks were stuck pointing skywards, moving up and down pointlessly as she tries to reposition them onto the table. She could feel her panties pressed tightly against her ass, still wet from her legs evaporating.
“Aagh! Are you kidding me?!” Shouted Tabitha in frustration. Her new massive breasts have rendered her completely immobile.
Before she could reassess her situation, Tabitha noticed that during her expansion, her hair has already turned into steam. She could feel the top of her head going numb as her vison starts to fade. So it’s come to this. The girl soon to be headless exhaled deeply before fully regaining her focus. I think I know how to finish the reversal solution now.
Darkness surrounded Tabitha. All the ambient noise of the laboratory was muted. As her mouth and nose went numb, her breathing stopped. She could feel herself beginning to suffocate. It was less than half a minute later when the top of her neck evaporated, revealing a small orifice in its center through which she joyfully took a deep breath. As expected, her pelvis fell back onto the table as the only counterweight disappeared.
Tabitha stopped for a moment, taking in the unique sensation of exclusive touch. She noticed she could detect and measure the minute air currents flowing through the static room. The sudden calmness made her realize just how tired she really was. By now, the coffee would have worn off regardless of the existence of her brain. It bothered her how her brain remained functioning even when it no longer occupied space. As her thoughts drifted into limbo, an idea crossed her mind. This night has been the most enjoyable experience in her entire life.
A few minutes passed, before Tabitha’s wits came back to her. She knows she doesn’t have much time before the next part of her evaporates. Whether she will end up as a just a callipygian lump of sex organs or a small chest balanced on two gigantic tits, she was not particularly interested. She reviewed her plan to avoid her doom, the first step being for her to remove her underwear.
Tabitha pushed sideways against the table with her pelvis, creating a torque which rotated her light body about her heavy chest. She could feel the surface squish tightly against her clitoris every time she turns. After turning her pelvis towards the chemical rack, she feels around with her crotch for another hook-shaped component. Once she’s found a sharp overhang on the rack, she pulled off her underwear with the same trick she used on her dress. Instantly, she could feel the freezing air brush against her hairless crotch, her thick labia folds were still moist from the fabric. Tabitha tried thinking about her collection of Yaoi comics to lubricate herself for the next step of the plan. My body is ready. She thought ironically. It’s probably going to be no different than the time with Frank. Only a lot bigger I suppose.
Twisting around her hips, Tabitha positioned her vagina on top of the test tube containing the Reverse Formula and forced herself downwards with all her strength. The glassware was around 2 inches in diameter, and initially resisted penetrating her tight opening. As her fluids dripped down the shaft of the tube, the surface was lubricated enough to be forced 3 inches into her. Having fit the Reverse Formula snugly into her, she knew it was not deep enough for the fluid temperature to reach 25 degrees. She lifted her pelvis again, and started pushing off the table towards the sink on the other end, firmly holding the tube inside her.
Tabitha moved like a caterpillar. Having such massive breasts limiting her range of movement and giving her significant inertia, each push off the table made her drive the test tube further and further into her. The sliding motion of the glass surface across her vaginal cavity stimulated her deep nerves, encouraging her to crawl harder and faster. By the time she reached the edge of the sink, the 12 inch long test tube was completely inside her. She squirmed around in both pain and pleasure, knowing she won’t be able to remove the glass tube stuck insider her without a pair of strong arms.
After warming the Reverse Drug for several minutes, Tabitha was ready to move onto the next stage. She knew she had to get the liquid into the hole in her neck somehow, as the drug was made to be ingested much like the Preserver Drug. Lying near the edge, she gave one final push which landed her neck-first into the sink basin.
Tabitha was now upside down, with the test tube inside her pointing skyward. The sink was barely large enough to fit her torso and breasts. She tried recalling her next move before realizing she hadn’t really thought her plan through after this point. She simply expected herself to improvise the Reverse Drug into her neck hole.
Since the test tube was still corked, Tabitha moved her hips around; trying to bump against the sink spout which she knew was a long crane-shaped pipe arching downwards. She felt the steel plumbing touch her butt, so she leaned her torso around the spout and bent forward so that the test tube cork was aligned with the spout nozzle. With a well-executed contraction of her abdomen, she forced out the test tube cork against the sink nozzle, spilling a fraction of the Reverse Formula. The fluid fell onto the base of her breasts, flowing through her cleavage into the bottom of the sink without going near her neck hole. It appears that spilling the solution won’t allow her to drink it.
Alright Tabi, final stretch. Just need to drink this and you’re in the clear. Tabitha went through all possible ways she could move her hips, and each corresponding trajectory of the spilled fluid. Being upside down and almost completely stuck, she could not think of anything with the slightest chance of success. Her waist and hip muscles grew tired holding the test tube upright, so she twisted her pelvis back to its original position, once again having the sink spout between her buttocks. She rested her pelvis against it, the spout digging into her butt. Might it be morning yet? She wondered. With all that’s happened, being in this position at least lets me mess with the first guy to walk in here.
Suddenly, Tabitha could feel her nipples going numb, and the sensation of steam on her stomach moments later.  She’s evaporating again. Knowing that without a torso, she would have no way of ingesting reverse solution, she grew nervous. As the bulk of her breasts disappeared, her center of balance shifted forward, causing her lower half to topple over. Lacking the time to react, she accidentally spilled the rest of the reverse solution onto herself. The fluid quickly flowed past her curves and onto the sink floor.
No! Don’t you leave on me! Tabitha could feel her bastion of hope trickle away into the drainage. Acting on the first plan that came to her mind she immediately bent her waist back towards the spout. She slid her buttocks down the sink spout until the nozzle aligned with her anus.
Tabitha then straightened her torso, plunging the spout deep into her. AGHH! This plan is a pile of dicks! She cried internally, enduring the tortuous sliding of her rectum against the geometrically shaped spout. Boy do I just love fucking inanimate objects today don’t I. She forced the shaft of the spout into herself as much as she could until she was pushing off of her neck stump, making it barely tangent to the sink floor. Luckily, a few small puddles of the reverse solution have not yet drained. The girl desperately sucked the spilled fluids through her neck hole. Since her penetrated pelvis was now mounted onto the sink spout, she could move her torso around freely by twisting her waist. She vacuumed into her as much of the reverse solution as possible. She managed to ingest only a few teaspoons of her antidote. Whether such tiny quantities were enough to restore her body, she was not sure at all.
By this time, Tabitha’s breasts were completely gone. She could sense that her torso was now evaporating from her shoulders. Given this brief moment of mobility, she violently flailed her torso around, trying to feel for the handle which controls the water. Even if the reverse solution worked, her limbs would need to absorb water to grow back. She managed to nudge the cold water handle with her vanishing ribcage. As she anticipated what would happen next, her upper half had completely evaporated replacing her midsection with a smooth surface. She was now nothing more than a pair of hips, fixed upside down to a sink spout with both her orifices deeply penetrated.
Moments later, water trickled from the spout, flowing directly into Tabitha and slowly filling her colon. Knowing this is the moment of truth, the girl who became a set of hips crossed her metaphorical fingers hoping that her limbs would regrow. She could feel herself gradually getting heavier as the water insider her pushed her down. Eventually, her weight became stronger than the grip her anal sphincter had on the spout, and she slowly slipped down the shaft. A feeling of relief came as the spout was released from her anus, followed by the immediate pain of falling onto the sink floor. To Tabitha, the impact didn’t hit nearly as hard as the post-anal soreness.
With her genitals still pointed upward, the water splashed onto Tabitha’s labia and clitoris, dripping into the test tube deep inside her. Even without a heart and lungs, she could feel her body heating up and blood flow quickening. Without any of her other senses, the water dripping onto her crotch hits her with the most intense waves of pleasure. Unable to move at all, she was subjected to the watery massage for well over a minute before it brought her to climax. She spasmed as much as she could in her abbreviated form. Her pelvic muscles tightened and she tried to release her vaginal juices, but was corked by the test tube stuffed inside her.
Tabitha was fully spent. The entire experience greatly outranked every instance of her past sexual encounters. To her surprise, she realized she didn’t even notice the formation of her lower waist and upper thighs during her climax. It worked! My fucked-up shit-plan actually worked! With her midsection regrown, she could now wiggle in celebration. You’ve fucking aced it this time Tabi, beating your own genius invention with an even more genius test tube in the pussy and a brilliant pipe in the butthole. You better be proud of yourself you magnificent ho-bag of science!
As Tabitha relished in her victory, her legs and torso have finished forming. As her breasts were protruding from her chest, she could feel then grow past their original size and stop once they’ve reached the shape of basketballs again. She was greatly disappointed by this outcome as she dreads of the foreshadowing back pain.
As Tabitha’s head started to emerge, she propped herself up towards the sitting position by pushing against the edge of the sink with her thighs. Seconds later, she could feel her senses return to her. She opened her newly formed eyes to discover the morning sun already illuminating the room. She looked at the clock. 8:07 am. There must already be people in the building by now. Anyone passing by the hallway could have glimpsed past the door window and saw her in her naked and helpless form.
Hoping to avoid an awkward confrontation, Tabitha used her forelegs to turn the sink handle all the way. Much more water rushed out, splashing all over her and accelerating the growth of her legs. Without thinking, she pushed herself out of the sink once her legs were completed, leaving her neglected arms as tiny stumps. She knew she has to get out of the room quickly and could grow back the rest of her once she gets home.
As Tabitha hopped off the table, she immediately tripped and fell to the floor. Her new breasts were incredibly heavy, and shifted her center of balance to unfamiliar places. She carefully got up by leaning against the cabinets and grabbed the underwear hanging from the chemicals rack with her mouth and dropping it into her backpack. Adjusting her gait to account for her breasts, she rushed around the room, picking up the coffee cup and bra with her teeth and dropping them into the backpack as well. My new bra is probably going to be a wheelbarrow. Thought Tabitha as she lied down next to her dress, sliding her head through the bottom of her skirt. The slender dress couldn’t go any further when its narrow waist reached her two breasts. Denying the option of heading outside with her genitals fully visible, she dragged herself across the floor, forcing her chest through the waistline.
The dress was eventually caught on a chair leg, Tabitha’s breasts ripped a tear straight down the neckline of the dress as her head emerged from the top. Standing up, she looked down at her enormous breasts, which protruded through the tear in dress, her nipples more prominent than ever. The tear itself was deep and went past the waist line, stopping just above her bare vagina. It was then that Tabitha’s hindsight kicked in as she regretted not restoring her arms.
Giving up, Tabitha remembered that topless ness was technically legal. So she grabbed the handle on her backpack with her teeth and walked out of the door into a sparely populated hallway. She hurried home, wanting nothing more than a long awaited nap, as passersby were stunned by her gigantic bare chest and armless physique.
I kind of want to do this again. Thought Tabitha as she ran across the city streets.
