You rest, having set a new PR on the in lab-gym squat rack. Your thighs are really shaping up. You jot down your progress not the clipboard.

It’s hard to believe you were overweight bordering on obese only 2 years ago. You used to endure some teasing for your ‘fluffier build’. you were able to shed the weight and turn it all into muscle.

The gains you had made were beyond normal human physiology. This gym was in a larger testing facility. It catered to all kinds of interest both scientific and.. otherwise. You had heard rumors of unethical experiments on some of the floors, but all the files were redacted and access limited.

After graduating with a PhD, you had joined up and agreed to a test a regimen for the lab/company. Turns out it was a fitness regimen with personal trainer, advance drugs, and DNA therapy. And the results were incredible.

As you bounce doing jump rope skips, you somewhat missed the softness sometimes, but not enough to give up all you’ve worked for. You love feeling fit and showing off you bod! Then you get a text from your boss, or rather your boss’s advanced AI agent.

“Hey <employee name> new assignment for you.”

You roll your eyes. They couldn’t even be bothered to fill in your name properly. But then you scan the message and your eyes light up. A Promotion!

You slip on your lab coat over your fitness attire and hurry out of the gym. You head down a lab corridor to the designated doorway. It’s priority access and now for the first time you HAVE access.

Your eyes get scanned by a green laser lock beside the door. With a click and hiss the doorway opens and you stroll inside cautiously.

It is…. !

….

more of the the exact same hallway with closed doors. A bit anticlimactic but what did you expect. Reading the file as you walk you see it is largely redacted.

‘Adipose… gainer shake… huh?’ You read aloud the unreacted words until you reach your new assigned door A22. It opens with a hand scanner.

You enter a simple room, almost like an apartment. You stumble slightly feeling oddly… light? Less heavy? The only thing of note is everything is super LARGE and reinforced. The couch could fit 5, the chairs seem designed to work in tandem for one large person. Robotic arms work making some kind of shake in the kitchen. That’s not surprising, automated robots and tools work all over the facility. Then you see something that makes your eyes pop!

Resting in a specialize stasis bed, sucking from a tube is an absolutely massively obese person. It takes you a moment to tell they are even male due to the sheer immensity. You are amazed, jaw dropping, until you get another ping from your boss/AI.

“Task: wake and acclimate subject code L@RD-A22 to test environment. Subject has been in stasis for 1 year duration. Record and manage subject.”

Whoa your job was to wake up and help out the guy!?! You notice a monitor with all kinds of controls: feeder shake, hypnosis controls and trigger, gravity level set to 85%, robot arms control, personal gym.. wait gravity?

You move over and adjust the slider down. Immediately you feel lighter. You toss a pen in the air and it falls slower. This must be why you tripped when you entered.

“WILD!” This was beyond any tech you’d seen at the facility! You toggle the personal gym and find a massive gym where someone massive could workout. The treadmill is 10x wider than a normal one. There’s an entire pool in here too!

“They must be super interested in you big guy…”

As you turn to approach you notice something, you recognize the guy! Your heart skipped a beat…

Hello! Thank you for reading my prompt. Hope it excites you enough to reach out. The main point of this is a role-reversal story where your character is now fit and mine is obese. Up to you on how we know each other. Maybe we were classmates, lovers, maybe you had an unrequited crush on me, maybe I used to bully you, all options are on the table. Down for M, F, Trans, NB, or other partners, however you want. Option: You could also play an android working in the facility. I have no size limits and kinks are negotiable. Feel free to suggest anything as I'm open to most kinks. I can even play furry, if that's what you desire. You character can be fit, butt, slim, or thick-fat up to you. I don't judge or kink shame and the worst I'll say is no. Password is: ‘Biscuit’, please include in your message so I know you read the whole post. Limits: Violence and gore, death, identity death, feral, and the more traditional taboos everyone should know. Looking forward to hearing from you! Even if this prompt is a few days or even weeks old, don't hesitate to reach out if this interests you. I can chat here or on discord.
