1.)
Robert looked at the lab mice and his chest swelled with pride. They were exceptionally large with visibly rippling muscles that dwarfed those of their peers. His experiment on them was a resounding success, and with a few small modifications, his latest project would be ready to be tested on a living human being.
The concept was simple: a serum that, when ingested, would increase a person’s strength, size, durability and overall athletic performance. He predicted it would cause a modest, but noticeable 10 percent increase in a human being’s base genetic potential. That was to say, somebody enhanced by the serum still needed a strong base to work off of and to put in the effort of training their bodies for any real results to occur. These attributes all being increased at the same time would have a synergistic effect. While the recipient’s muscle size might increase by 10%, they would also become 10% more efficient, 10% more durable, so on and so forth. The full extent of these things working together was somewhat frightening when Robert dwelled on it. It also had the potential aid one’s cognitive abilities, as it would theoretically make neural connections more efficient.
Robert needed this serum to work. Ever since the brilliant 28 year old scientist had left his comfortable position at MegaMed corporation he had yet to produce anything to show for it. His funds were dwindling day by day, and his peers were beginning to doubt if he really could strike it out on his own.
There was one large kink in his plan: the serum barely worked at all on males. It had some effect, but it was much more pronounced on the female mice. Robert was pretty positive this was due to testosterone inhibiting the serum, or perhaps estrogen facilitating it. Regardless, if he could get the product to market, almost every woman alive would be interested. Plus, even if it only provided an small increase for men, very few would turn away the opportunity to use it themselves.
He ran into one final roadblock: how would he possibly test the serum? He could just inject himself, but that had numerous ethical concerns regarding his perception on how successful the serum was. Besides, he really needed to make sure it worked on women. Robert could just offer a lot of money to a random person, but that also had a great deal of potential problems: What if they didn’t follow his directions? What if they were difficult to work with? What if the serum worked too well and they weren’t morally ready to possess that much power?
After a great deal of deliberation, Robert decided that he would call in one of his former assistants from MegaMed – a woman two years younger than him named Emma. Robert knew that Emma held a great deal of respect for Robert, and he secretly nursed a crush on her. The concept of Emma growing taller, stronger and all around better was quite thrilling. On the other hand, it did worry him that the project could have an adverse effect on her. Despite these misgivings, Robert was supremely confident that the serum would at worst have no effect. Regardless, Robert’s stint of independent research was probably doomed if the serum didn’t work. With that in mind, he threw caution to the wind and gave Emma a call.
–
A few hours later, Emma arrived at his house. Despite not being at work, she still wore her lab coat with a sweater and khaki pants underneath. In her hand was an over sized duffel bag containing some personal belongings, as Robert had explained that it could be an extensive research session. Emma had gone ahead and packed an extra pair of clothing as she secretly hoped to spend the night with him.
Similar to Robert, Emma possessed dark hair and a pair of large glasses. Unlike Robert however, she had put some time into prettying herself up a little for the encounter.
“H-hey Robert.” She stuttered, entering his spacious home. “It’s been a while.”
“Yeah, it has.” Robert affirmed.
It was an awkward moment. Neither of the scientists had ever been particularly good at social encounters, especially outside of the workplace.
“Are you okay? You look kind of…” Emma started, unsure of how to finish her thought without sounding rude.
Robert turned a shade red. His hair was disheveled, and his typically well-groomed facial hair was a scraggly mess. He was also even thinner and a bit paler than the last time Emma had seen him months ago. “Yeah. Been really caught up in this project. Sorry for the appearance.”
“Oh, it’s okay. You still look fine to me.” Both Emma and Robert blushed slightly.
Their eyes met in another bumbling moment. “Right, well, let me show you what I’ve got and why I potentially need your help.” Robert interjected, leading her into his central home-lab.
–
Robert showed Emma the mice and explained the ultimate goal of the serum, to be used on humans. Her eyes grew wide at the sight of the buffed up critters. Robert’s claims would have typically sounded like wild fiction, but the proof the rodents provided was undeniable.
“So… where do I fit into this? It sounds like you have everything under control.” Emma asked.
“I do. I just… need somebody to test the serum out on. Preferably a female since for one reason or another it doesn’t work so well on males.”
While she wasn’t as brilliant a scientist as Robert, Emma was still a bright girl and quickly connected the dots. “Robert… are you serious?”
Robert’s stomach churned. “You don’t have to if you don’t want to! It’s just that… well, I trust you.”
Emma blinked a few times, processing the information. “And… there’s nobody else you trusted with this?”
“I dunno. I can’t really properly put it into words. It’d just feel weird seeing the potential effects on other people.”
Emma pursed her lips. She was unsure exactly how to perceive Robert’s statement. “I see. Well, would it be okay if I go over the research myself?”
“Of course! If you’re going to inject this into your body you may as well know what’s going on with it.” Robert lead her to his desktop PC and opened up the project files.
The brunette glanced over the data. Despite being well educated woman, most of the research was a mystery to her. She began to slowly piece together what it all meant, but it was still out of her league. Regardless, everything she did recognize looked solid, and those mice proved that it had some effect. Her mind began to race with thoughts of the serum working on her. Emma was always a bit on the short side. Being taller and stronger… that sounded pretty awesome. Plus, if her rudimentary understanding of what she was reading was correct, her breasts would likely grow larger as well.
Emma bit her lip as she continued to think over Robert’s proposition. She was more so biding her time to dwell on the decision at hand rather than actually analyze the data in front of her. If this serum was a success, it had wide-scale implications for the entire human race. Had Robert even considered that? It would slightly close the gap between men and women. In fact, in some areas it would push women ahead of men. On that note, the fastest human being alive would almost certainly be a woman after a 10% increase. On the flip side, if the serum’s imperfection involving testosterone were to be cleared, it would, in a sense it would widen the gap.
Emma shook her head a bit. The societal implications of this serum weren’t what was at hand. She needed to figure out whether or not she was going to test it. There was an element of risk, but this was her chance – her opportunity to become something special. Plus, if the serum DID become real commercial product, it would likely cost an arm and a leg. “Alright.” She finally spoke up. “I’ll do it.”
“Yes!” Robert cheered up. After months of turmoil in near isolation, today was turning all of that around.
2.)
Emma sat on a stool waiting for Robert to finish preparing to give her the serum. Her mind was aflutter with the possibilities of what could happen. While Emma was a morally grounded individual, even she couldn’t help but dream of becoming a being of greatness. Secretly she hoped the serum would work beyond the projected 10%, turning her into a superwoman. What if the serum failed? Well, if it did nothing that wouldn’t be much of a problem, just a let down… but what if things went terribly? What if it made her even weaker, or worse yet something drastic like gave her cancer? A shudder ran down her spine. Emma snapped out of it – she trusted Robert, and the possibility of making history was too great to pass up.
Robert finally emerged, holding a massive hypodermic needle in his hand. It was easily a foot long in length with a thick, menacing steel tip. In fact, the implement so large that it was almost comical. Emma’s eyes grew wide. “Holy sh-” she cut herself off.
“Oh, yes, sorry. The entirety of the serum needs to be injected all at once to ensure it’ll take effect.” Robert explained.
Emma gulped. “Well… alright. So where will you be injecting it?”
“In the upper arm would be best.”
“Right.” Emma took her turtleneck sweater off, revealing a thin pale body in a tank top. Emma wasn’t homely by any means, but she had a few imperfections on her skin – small blotches, freckles and scars. The young woman’s body lacked a distinct feminine shape as only a tiny amount of visible muscle could be seen solely due to her low body fat.
“Okay. I recommend you close your eyes.” Robert said as he brought an alcohol swab to her arm, rubbing the are that he would inject with the needle. Emma complied with his request and a moment later her teeth grit tightly as the steel pierced her skin. Another moment passed and the entirety of the serum had entered her system. Emma felt somewhat warm and a bit tingly, but that was about it.
“N-now what?” Emma asked.
Robert shrugged. “We wait.”
Emma slipped her sweater back on.
–
The next couple of hours were fairly awkward. Both Robert and Emma were unsure of how to approach the other. They each felt something for one another, but had never acted on it. Being thrust into an isolated environment with this experiment as a pretense only served to complicate things.
They opted to idly browse the internet on their respective devices: Robert his PC and Emma her tablet. Finally, two hours after being indoctrinated with the serum, Emma felt something.
“Robert.” She said standing up, clutching her thin midsection.
Robert quickly reacted. “Yes!?”
“I’m… really, really hungry.” Emma responded.
Robert let out a sigh of relief. “Well that’s good. Let’s get you something to eat.” He said, leading her into the kitchen.
–
Twenty minutes later Emma was shoveling another slice of pizza into her mouth. Her appetite seemed endless. Robert watched with rapt fascination as the relatively small woman inhaled more sustenance than he could manage in an entire day if he forced himself. The scientist held onto a clipboard as he took notes, though in reality he was mostly observing Emma.
Having lived alone for a long time, and lacking the motivation to cook properly, Robert had subsided off of easy to make bachelor meals such as instant noodles and frozen dinners. It was only a matter of time until Emma had eaten everything he had, resulting in him ordering a two large pizzas. In hindsight Robert should have prepared for this ahead of time, but for now greasy, high calorie pizza would have to suffice.
“You’re sure it’s going to be fine if I eat all of this?” Emma asked before swallowing another bite.
Robert nodded. “Presuming everything is going as planned… Your metabolism should be speeding up. While at a surface level you’d think it would be a flat 10% increase like everything else, since so many various aspects of your body will be increased, I’d estimate your metabolism would rev up considerably more than that.”
“Still this is waay more than… well, even double what I’d normally have in a meal!” Emma finished off the first large pepperoni pie, still feeling hunger pains.
Robert shrugged. “The worst thing we could do would be to not listen to your body. We’ll give it the fuel it needs.” He explained grabbing another box and opening it up in front of her.
–
Another twenty minutes passed and Emma finished both large pizzas. Robert had been too busy watching Emma and taking ‘notes’ to bother eating at all. His stomach grumbled. There was no more food in the house. Emma patted a forming ‘food baby’ of pizza before her own stomach grumbled as well.
“Still hungry?” Robert asked.
“Yeah…” Emma admitted, feeling embarrassed.
“No problem. We should get some Chinese. A LOT of it.” Robert offered grabbing his cell phone.
“Sounds good, but, you should let me pay.” Emma said producing her wallet.
“Emma?”
“I mean, it’s only fair. You’re already giving me money just for doing this and I’m the one eating all of the food.”
Robert shook his head. “Nonsense. Consider it a research expense.”
Emma scrunched her face. “Alright…”
–
The rest of the evening went by without much incident. Emma had eaten a large portion of the Chinese food as well, but Robert finally got to have a meal himself. Unsure of how else to pass the time, they watched television together. Emma had always been a sharp minded girl, but that night she felt really on point. They watched a nature documentary and Emma could feel her mind taking in the information even more easily than she typically could.
Eventually both Emma and Robert grew tired. Too timid to make a move on each other, Emma slept in the house’s guest bedroom. Robert found immense difficulty sleeping at all as a strong case of insomnia overtook him. The scientist’s mind was abuzz with the potential implications of the serum. He couldn’t wait to cash in while improving quality of life worldwide. His thoughts were also consumed by Emma. Robert wondered precisely how the serum would change her, and the implications it could have for their friendship. At some point, Robert’s body forced him to sleep for a few scant hours.
3.)
As Emma awoke she was greeted to something very peculiar: her vision was clear. For as long as she could remember, she always awoke to a blurred field of vision. Flabbergasted, Emma grabbed her glasses and put them on, only to discover that the lenses only made her vision worse. She took the thick spectacles off and once again she could see clearly.
Excitement built within her as the implications of this discovery began to dawn on her. She no longer needed glasses! At the very least the serum had enhanced something about her. Before Emma could get her barrings, the familiar hunger pains from the evening prior returned. She scuttled out of bed and made her way into the living room, still wearing the same clothing from the day prior. Emma found that the clothing was surprisingly tight on her body, but she managed to slip it on regardless.
Robert was already awake, thick bags had formed under his eyes from lack of sleep. As soon as he laid eyes on her he let out an audible gasp. “Emma!” he exclaimed.
“Hmm?”
“You… we need to measure you!” Robert’s expressions had changed from tired to animated in a mere few moments.
“What?”
Robert pointed at her now-exposed midriff. Due to her recent growth spurt, a swath of remarkably toned and feminine flesh was visible. Emma reached down and brought it up slightly, revealing the beginnings of a lithe six-pack. “Woops. I guess I really DID grow.” She observed, bringing her shirt down in an attempt to cover the skin, but failing to fully do so.
Robert glanced up and noticed just how tight Emma’s sweater was. Her upper body had widened considerably, and her once small breasts expanded at least one cup size, possibly two.
The scientist quickly waved Emma over to a wall where he had set up a measuring station specifically for this occasion. As Emma drew closer to him, it became quickly apparent why Robert was so flabbergasted: she was looking DOWN at him! There was no way around it, Emma was already taller than he was. In fact, she stood nearly half of a head higher than he did!
Eagerly, Robert grabbed a nearby measuring tape and began to record how tall Emma was now. “5 foot 11 inches!” Robert yelled out. That was 3 inches over his below-average 5’8”.
“Oh wow…” Emma murmured. “It really did work!”
Robert ran across the room, grabbed a notebook and jogged back before hastily jotting something down. “Do you remember how tall you were before this?”
“I’m pretty sure I was 5 foot 6.” Emma explained.
“66 inches to start…” Robert murmured, his mind buzzing. “10 percent of that would be 6 point 6…”
“Is everything okay Robert?” Emma asked.
Robert nodded. “I really didn’t expect height to increase much at all. There was the possibility of the body adjusting to compensate for added muscle, but…” Robert cut himself off. “Emma… where are your glasses?”
“Oh! Right! I almost forgot. It seems that I don’t need them anymore.” She explained with a confident smile. “I’m pretty sure it was due to the serum.”
Robert was at a loss for words. The serum worked! In fact, it not only worked, but it was causing improvements he hadn’t even considered. As Robert examined Emma, he couldn’t help but notice how beautiful she was without glasses. A light pink blush met his face and he tried to distract himself from thinking about how attractive the woman in front of him was.
“We should record your weight too.”
Emma shifted about a bit, as a fairly typical woman she was somewhat adverse to the idea of being weighed. Still, she knew it was for a good cause, and it wasn’t like she had any fat on her – so whatever weight she carried must have been mostly muscle.
Robert led the taller woman to a scale and she stepped onto it. A moment passed and an electronic display read ‘184’. Emma let out a audible “eep!” when she saw the number. “Is this thing accurate!?” she cried out loud.
“Hmm… that does seem high. Step off for a moment.”
Emma complied with his command. Robert stooped down and pressed a few buttons, clearing the device for calibration before standing on it himself. A few seconds passed and the display read ‘157’ “Seems accurate. Guess I lost about 5 pounds the past few months.” He said with a shrug. “Try it again.” He offered stepping off the device.
Emma gulped and placed her feet on the plate. Once again it read ‘184’. Before Emma could say another word, Robert had retrieved a pair of calipers. “From a quick glance I wouldn’t worry about the numbers being high. We should take a record of your body fat percentage regardless.”
Not wanting to impose on the woman, Robert handed her the measuring tool and instructed her on how to measure herself. She ended up with an estimated 19%, which put her in the very healthy range.
–
After taking measurements and consuming a quick breakfast consisting of leftover takeout, Robert and Emma freshened up for the day ahead. Against their primal urges, they showered separately, Emma using the guest bedrooms’ bathroom. Robert took extra care to properly groom himself and dress in a more flattering manor. Emma on the other hand enjoyed running her hands over the contours of her new body. Her now tall frame had filled out considerably from the stick thin girl she was a mere day ago.
–
An hour later Robert was driving Emma to the mall. He offered to procure some new clothing to fit Emma’s growing body, and on the way back they’d stop for groceries. As they moved through the mall Emma received more than her fair share of glances from various onlookers. They eventually managed to purchase a wide variety of outfits, and grabbed a few that were a couple sizes larger than Emma’s current state just to be safe. The grocery store was a similar affair – many onlookers while Emma and Robert filled up an entire shopping cart each. They purchased a huge bevy of meat, fruit, vegetables, calorie dense snacks and premade protein shakes in an attempt to ensure Emma’s appetite could be properly quelled.
Eventually Robert and Emma made their way back to Robert’s lofty manor. It didn’t take long for Emma to become hungry again, leading her to break into some food requiring no preperation. After Emma was satiated, Robert suggested they perform some testing. Emma gladly agreed.
The scientist set the growing girl up in front of his computer where he had a mental capability test setup. It presented her with a series of logic puzzles and also tested her reaction time. She scored fairly high on the logic and reasoning puzzles, placing her in the theoretical top 85th percentile of human beings, and similarly high on reaction speed: 79th percentile. Robert realized immediately that in his haste to have a human subject test the serum he had forgotten to test Emma before being indoctrinated with the serum. Regardless, they now had a measuring stick to see if Emma made any further improvements.
After completing the mental tests, Robert brought Emma into a small home gym to see how she would perform physically. Emma stripped down to a tank top and changed into a new pair of athletic shorts. Her frame was already visibly thick with no fat aside from her fairly sizable breasts. Robert also noted that most of the freckles and blemishes he noticed the day before had cleared up. He was unsure if that was due to the serum or a good night’s rest.
Despite possessing a body that was apparently already quite athletic to Robert, Emma worried somewhat about her performance. She had always been an unathletic child growing up, leading her to perform poorly in gym class, which garnered her some mild ridicule.
Emma fought down her fears and grabbed a pair of weights, 20 pound dumbbells, bringing them over to a bench press. Robert once again realized how foolish he had been in not recording Emma’s lifting stats before the serum. Still, it was too late for that. Emma began to press the weights up in a chest press motion. It was a nearly effortless task for the woman and after a dozen repetitions Robert suggested she try more weight. Emboldened by her success, Emma gladly accepted, moving up to a pair of 30s, which were also fairly easy for her to press. Finally, Emma was challenged by the 40 pound dumbbells, and felt a pleasurable release of endorphins flood her system. Emma had never bothered trying to properly work out before, but she was already enjoying it.
They ran through a small gauntlet of exercises and Robert diligently recorded each and every result. For the most part, Emma scored quite highly for a woman. With each workout, she felt more of her body becoming ‘pumped’ as her somewhat thick limbs revealed a canvas of small muscles.
“Check it out!” Emma exclaimed cheerfully, bringing her arm down, causing a small tricep to pop out.
Robert brought his hand up and cupped it. “Wow, this is really hard.” He remarked, blushing.
Emma noticed his face turning a familiar shade of pink. “You like it?”
“Ummm…” He mulled the question over for a moment. “Yeah.” He admitted.
“You sure? I mean I know it’s usually considered unattractive for a woman to have muscles.”
“No! Not that. I like them. I just…” Robert was unsure how to put his words into a coherent sentence.
“Just to be clear.” Emma started. “You like these?” she performed a classic double bicep shot causing a pair of well toned biceps to erupt.
Robert blinked a couple of times. “Yes.”
Emma could tell from his expression that he was being genuine. She pumped her arms a couple of times, reveling in how Robert’s eyes remained transfixed on them. “Would you still like them if they were bigger?”
Robert gulped. “Yes.”
Emma giggled. “What if they were REALLY big.”
“Like… uh… how big?”
“Oh, I dunno… what if they were like… tremendously big!? Bigger than your head?!”
Robert was surprised at how alive and animated Emma was. Normally she was an extremely reserved girl. “I… would you think I’m weird if I admitted that’d be kind of hot?”
Emma giggled again. “Nope.” She finally stopped her flexing show. “Unfortunately, that would lie well outside the parameters of what the serum is supposed to grant.”
“Right.” Robert agreed, collecting himself. “Well, I think we’ve properly gauged your physical progress. I’m going to go compile the data and take care of some things.”
“Okay. Say, want me to make dinner? It’s the least I can do. Especially after you bought me all those clothes, and food, and well, this body.”
Robert agreed, expressing his gratitude for Emma’s gesture, and with that they went off to complete their tasks.
