Chapter 1 - Rat Race

Warning* This is a piece of weight gain literature involving role reversal, weight gain, weight loss, and figure swapping. If that’s not your thing, please do not read.


As a junior in college Lexi was looking for work studies to complete her mandatory college credit requirements as a social worker. While her field of study was hard to find internships in behavioral science, she had always set participating in case studies on the back-burner as she felt it wouldn’t benefit her as greatly in her own studies compared to being on the administrative side of the experiment. With time winding down before she had to make a definitive decision for Fall Semester courses, she visited the campus lab to scour the public case study listings in a ditch effort.


On a wall covered in fliers, one freshly printed page tacked on top caught her eye.


Paid accredited study:
Cognitive connection to Metabolic and Behavioral traits.
2 openings/16 month term
*Walk-in interviews accepted.
Check in @ Lobby


Snagging the page from off of the bulletin board to prevent further competition to follow, she stuffed the flier into her purse and continued to the lobby. Pushing the door open, she strut into the room in full interview mode exerting confidence and purpose. The women at the desk rolled her eyes as she watched the athletic young women seductively approach the counter with debatably too much leg and tanned midriff showing through her revealing choice in clothes.


“Hey there, I’m Lexi. Just coming in to inquire about the Behavioral Traits case study posted outside.”


“Nice to meet you Lexi, one second and I’ll be right with you. “I’m Diana by the way.”
As she licked her finger and began flipping through her appointment binder, she couldn’t help but feel some immediate disdain towards the girl looking at her through the plexiglass divider. As a significantly chubby woman herself in her mid-30’s, Diana had seen skinny girls like Lexi use their looks to thrust themselves into the clinical studies time and time again. Just then, the correct study caught her eye.


“Aw yes, the cognitive swap study with Dr. Reyes.” Diana said as she began to remember the background of the case study.
Stammering, “I-I mean yes, the Behavioral Traits case study. Let me buzz the Doctor in to get you set up. Please sign these forms for me and take a seat for a moment while they prepare.”


Handing the papers away, Diana couldn’t help but smile as she watched Lexi turn around to walk to the sitting area.


Not so long after Dr. Reyes walked through the door with a clipboard, “Lexi Downey?”
Lexi got up from her seat and shook the doctor’s hand as they exchanged papers and greetings during the walk to the conference room in which the interviews took place.


As they took a seat Dr. Reyes eyed up Lexi, taking in her lithe form, and began with some questions.


“So, I see you’re looking for Behavioral credits here at Emmanuel College. Is that all you’re trying seek from an experience like this?” Dr. Reyes said bluntly.
“I am definitely in need of the credits to meet my requirements though I am mostly interested in the takeaways from the study. Something I can use one day to help save a clients life in practice.” Lexi said staring at the intimidating female doctor sitting only feet across from her.


Dr. Reyes internally was unimpressed by the Miss America-like answer Lexi just regurgitated at her. Despite her premeditated response, Dr. Reyes thought someone this vain might actually be the kind of subject she’s looking for.
“Very well then, tell me about your physical activity levels, eating habits, and vices if you may?” replied Dr. Reyes.
“Well, I jog every day and have a few intramural sports I partake in. I eat pretty clean, no junk except when out with friends on occasion. Honestly, my biggest vice is drinking every now and then.” Lexi went on. “Is this case study based on physical health? If so I am a total health nut, I pride myself on my fitness for sure.”
“Now we can’t give away specifics but we are interested in a juxtaposition in the two subjects which puts you at a good place for us to set our sights.” says Dr. Reyes “How do you view obese people, if I might add.”
“Tough love is my approach, I think acknowledging their problem is important to start to make a change. I think fatties need our help to show them that they need to stop holding themselves back from a healthy life. Accountability, really.” said Lexi


Dr. Reyes made the educated guess that bringing up fitness might spark some extreme lifestyle indicators just by the outward appearance of the girl. Just as she presumed, it looks like she’ll have to find someone quite on the opposite side of the scale in order to bring some fruitful results to the study.


“Alright well, I believe I’ve heard all I need to hear for today, we will reach out to you in about a week or so if we decide to continue with you. Thanks again for your time.” Dr. Reyes said as she guided Lexi out of the room and into the lobby.


Diana shot Lexi a fake warm smile as she began to turn to the exit. As Lexi turned back forward she collided into a girl just walking in through the vestibule. Lexi fell to the ground as the other girl rested her cushy butt back onto the door she’d just opened. Albeit, Lexi was at fault for not looking where she was going, though the kind girl was quick to help her to her feet and apologize.
“You know you really need to watch where you’re going, especially when you’re as wide as the doorway.” Lexi muttered


Stunned at the nerve of that girl for fat shaming her as a total stranger, Alyssa brushed it off and proceeded into the lobby. Just then, she had a renewal of anger that immediately flared up as she turned around to rebuttal though by that time the girl was already gone. The only trace being a half crumpled piece of paper that must have fallen out of her purse. Being the decent person she was, Alyssa picked it up to go throw it away as she noticed what it read.


“Paid accredited study, cognitive connection to metabolic and behavioral traits. This is perfect, oh my god.” Alyssa said to herself
She sauntered up to the front desk and handed the flier to Diana with inquiries.
“Hey there, I’m sorry about what happened to you just then, she should’ve been the one apologizing to you. I’ll get you the forms for the case study by the way, just one second I have them right here.”


“Huff*, thanks. Diana, is it?” Alyssa said, reading her name tag.
“I just can’t believe she called out my weight like that.”
“She did what?” Diana said handing her the forms to sign.
“Yeah, super uncalled for if you ask me. As if she thinks I don’t know or something.” said Alyssa placing her hand begrudgingly on her tummy.

Diana’s heart went out to the girl as she walked away to the sitting area. Scanning over her body the girl looked everything as fat as Lexi looked fit. With a clear uncoordinated wobble to her walk, Diana could tell that this girl didn’t do much walking to say the least.


In what seemed like no time Dr. Reyes was back at the door with her clipboard in hand.
“Alyssa Rose?” said the doctor.
“Oh that’s me.” Alyssa said as she hoisted her body out of the tight chair.


Soon the two were seated in the same conference room going through similar questions with some drastically different responses.


“So tell me about your physical activity levels, eating habits, and vices if you have any? said Dr. Reyes as she eyed up the tubby girl seated across the table.
“Well, I try to walk to classes now and again but I’d say I’m pretty sedentary. Something I’m trying to get better at.” Alyssa said placing a hand on her distended bunched up belly. “My eating isn’t too much better as you could probably guess. My vices are usually watching shows for too long and ordering out. I’m not much of a partier”


“Interesting, that does place you as a good fit with one our past potential subjects. Well then Ms. Rose, I think we might be done here. I will most likely be in touch with you in the next week, assuming no curveballs are thrown into our schedule. Look forward to a call.” said Dr. Reyes proceeding to stand up and gather her papers.
“That sounds great Dr. Reyes, should I be concerned about any health risks pertaining to the case study?” said Alyssa
“I can’t give away information to the two potential subjects in fear of skewing data, but what I can say is that you, my dear, should have nothing to worry about.” replied Dr. Reyes with a kind smile on her face as she guided the portly girl through the corridor and back into the lobby.

After about a week and a half both Lexi and Alyssa were contacted with the positive news of being selected for the study. Both girls were to come in for the initial experiment and then expected to return bi-monthly for a shared physical evaluation for 8 months and the return for a follow up at the 16 month mark. If the study proved to be sufficient enough in results then the school would provide funding for a live seminar in front of the board of trustees.

As it turns out, both girls were set to meet the following Monday during the late night block of classes. While Lexi chose to walk to the clinic, Alyssa took the bus for sake of punctuality and so she could have a few snacks on the way to hold herself over until after the case study when she could grab dinner.


Alyssa was first to show up as she made small talk with Diana at the front desk and proceeded into a room with what seemed to be a CT scan or MRI machine. Lexi showed up soon after and went through the motions of talking to Diana in order to find out which room she was assigned. She approached a room that was set up much like Alyssas which happened to be on the opposite side of the wall. Both girls were given a hospital gown and asked to strip down to their undergarments.


Dr. Reyes opened the door to Alyssa’s room first, finding the portly girl dressed down to her gown as asked.
“Hello again Ms. Rose, I would like to thank you for accepting the program and will look forward to spending our next 16 months together during our check-ins. I am going to share a little background information on how things will be going down this evening. Firstly we will be hooking you up to our cognitive brain sensors while inside the scanner. You will be sedated for your safety while we use electroshock therapy to help guide certain habitual chemical reactions rooted in your brain to rewire to variable A. While the other subject will be wired to variable B. It is quite safe, you may however feel a bit groggy following the sedative for about 30 minutes. Everything is outlined in the abstract of the forms you’ve signed prior. Nothing to worry about.” explained Dr. Reyes as her two assistants began placing the sensors on Alyssa and applying the sedative.


“See you on the other side then.” said Alyssa lowering her head down onto the bed of the scanner.


Soon after Dr. Reyes approached Lexi’s room and gave a similar briefing before leaving to the command panel across the hall leaving her two assistants with the task of monitoring the two girls.


“Alright everyone it’s been 5 minutes since Ms. Downey has been sedated, let's pull in the scans.” said Dr. Reyes.
A 3D scan of both their forms each rotated in place on the large control panel touch screens. In seconds, larger proportioned models of each subjects brains were scanned to the screen.
“By now the computer is identifying which sensors in the brain are responsible for which behavioral trait.” We’ll start by naming Ms. Downey’s traits variable A and Ms. Rose’s variable B. With the transmitted neuralink we are going to copy and paste the metabolic functions related to gut health and energy burning to our clipboard of both the subjects and effectively transfer them from one to the other.” Reyes said as she spoke aloud to her students taking notes around her.
“Next is the habitual traits that lay inside the brain controlling diet, cravings, restraint, and strive a for physical activity. As you can see currently in variable A, the subject has a lot of activity in the neurons being sent to replenish ATP through exercise, while variable B due to inactivity stores their energy through primarily carbohydrates and fats with the mindset to store that energy. Same thing as before and, there we have it team. Once our subjects come to, they will be essentially living metabolic and behavioral mirrors of each others lives for the duration of the next 16 months.” As Reyes concluded a small round of applause from the team came and went and the assistance dispersed to tend to the sedated subjects.


Once the 30 minutes had passed and both girls were up on their feet. They were guided to a larger room to take their physicals together. Once inside the room Lexi was quick to notice the other subject as the girl who bumped into to her the week before. Alyssa was met with the same cruel realization.
“Ms. Rose, Ms. Downey, please make each others acquaintances as you will be seeing a lot of the other over the course of the study. Starting with disrobing down to your undergarments for us to take some initial KPI’s.” said Dr. Reyes
“What are KPI’s?” said Lexi with her arms crossed.
“Key progress indicators to track the metrics of the case study. Now robes off and follow Diana to the scale. I won’t be present for these as they’ll be recorded but I will pop in from time to time throughout the study.” said Dr. Reyes
“Right this way.” Diana said standing next to the scale as Dr. Reyes took off her glasses and left the examination room.




Being the confident alpha she was, Lexie dropped her robe and strutted over to Diana with gusto. After the sliding of some weights Diana confirmed, “126 lbs.”
“Your turn.” Lexie said stepping off the scale while glaring at Alyssa.
She sheepishly dropped her robe as both girls stood facing each other while taking in their bodies.


Lexi couldn’t help but crack a smile looking at the outright bloated figure that was Alyssa’s body. Lexi wouldn’t like to admit it but she had a gorgeous symmetrical face despite being obscured by a set of podgy cheeks and a double chin that was a testament to her low activity levels and poor eating habits. Her shoulders sloped into chunky arms, that bunched up with little rolls by her armpits. The backside of her upper arms slightly folded over her elbows and jostled with the slightest movement. Her forearms were puffy and connected to a set of plump little hands that definitely haven’t seen much physical use. She had a heavy set of tits being cradled in her bra that seemed proportionate on her porky body. They had to at least be E cups in Lexi’s mind. Below them sat a pale doughy gut that elapsed the waistband of her black panties. The way her belly wavered when she walked seemed to throw off her balance. Silvered stretch marks rested by her love handles that quivered as she walked past Lexi to the scale. With each unsure step her calves and thighs jostled in a way that made Lexi bring her hand to her mouth to stop her from audibly laughing at her chonky counterpart. Alyssa’s wide ass rhythmically bounced as it shook with every step. Squaring her up, Lexi would have guessed she was 5’3, the same as her. Even with the same shade of dirty blonde hair as herself done in a ponytail, one could have guessed she was her fat step sister if her dad had sex with a cow, she thought.


Diana slid the weights around and came to a conclusive weight. “274 lbs.” she said as Alyssa’s face blushed a deep red, feeling the criticism pouring out of that skinny bitch somewhere behind her.


“She’s so full of herself isn’t she? If only bodies were that simple, you should know I’m trying to get healthier!” Alyssa thought to herself


Glaring over at her with her smug face trying not to stifle a laugh, Alyssa couldn’t help but feel jealousy towards her body. Lexi’s face was cute with a strong jawline. Faint freckles blotted from cheek to cheek meeting over the bridge of her nose. Dirty blonde hair placed up in a messy bun that looked effortlessly perfect. Her trim neck sat on defined tan shoulders, carrying a set of feminine arms. Her boobs were on the small side of B cups which allowed her morning jogs to last without strain. Her torso was not particularly muscular but certainly fit and lithe. Having always been an athlete kept her tight and stretch mark free. Her hips were mesmerizing with the rhythm of her walk. They hugged the tops of her shapely built legs and caressed what was a powerful little bubble butt. Alyssa was jealous most of how comfortable she was in her skin, as if she knew what she had and was sneering at her for not not having it.


After the weighing, blood pressure was taken as well as height, resting heart rate, 50 yard dash, sit and reach flexibility, and the long jump. As one could imagine, Lexi absolutely crushed Alyssa in every category. As Alyssa stood slumped over with her hands on her knee’s gasping for air after the 50 yard dash, Lexi came over practically unwinded and gave her a smack on her exposed ass cheek. Since the weigh in Lexi had warmed up to starting small talk with Alyssa to establish some sort of communication. Especially if they’re going to be the only two in the study.
“Hey Lexi, what did I say about touching me.” squealed Alyssa in response
“Come on you can’t put that big thing on display like that and not expect a spank. Meet you in the lobby tubs, your girl needs to grab some food.” said Lexi heading to the door.


Alyssa stood there still with her hands on her knees sweating when it finally hit her. She’s not even hungry.
“Lets keep this tenacity and make her eat her words. I need to make some changes in my life.”
