Work Text:
“Tae-ah, what are you doing?” Namjoon asks his roommate as he takes in the hectic scene before him.
The kitchen is a total mess. Containers and measuring cups surround the blender as Taehyung tries to wipe up the mess of various powders and liquids spilled on the counter.
“I'm making a protein shake,” Taheyung asks, tongue poking out cutely as he focuses on cleaning. “It's not going that great, I can't seem to get the blender to do what I want.”
“Well you should probably put the lid on it before trying to blend,” Namjoon says looking at the splatters across their cabinets.
“Oh.” Taehyung says dumbly, as if he hadn't considered that. “That's a good idea hyung, I guess I should've watched a tutorial.”
Namjoon nods trying to keep himself from getting upset at his roommate. “Just clean the mess up okay. Hobi-hyung is coming by later and if he sees this we'll both get in trouble.”
Taehyung nods, but looks vaguely upset at his failed concoction.
“Maybe try buying the pre-made shakes,” Namjoon suggests as he walks away from the kitchen. “It will be a lot easier for you.”
⊹₊ ⋆
After the blender disaster it appears Taehyung takes Namjoon's advice and starts buying pre-made protein shakes. The older man is glad that they won't have any more kitchen mishaps, but he starts noticing a few things start happening with his roommate.
First, Taehyung must be buying in bulk because he never sees the younger man without a bottle. Morning, afternoon, and night Namjoon constantly sees Taehyung drinking a protein shake.
Second, he quickly realizes Taehyung isn't going to the gym. Or well…he is going but he's not going nearly enough to justify three protein shakes a day.
Third, Taehyung is getting fat and shows no signs of stopping anytime soon

Namjoon sets down his work bag with an audible thud. It's almost midnight and he's just now getting home. The office has been killing him lately, he's looking forward to taking a hot shower, eating his leftovers, and sleeping for the next 12 hours.
The older man hears the living room TV playing once he walks past the entry way. Taehyung must’ve fallen asleep watching dramas again. Namjoon pauses as he takes in the state of his roommate splayed out on the couch.
Taehyung is asleep and snoring, but that isn't what catches Namjoon's eye.
The younger man is absolutely spilling out of his pajamas. His old college shirt is essentially a crop top now, Taehyung's wide, soft middle left completely uncovered from where the fabrics ridden up. Stretch marks, new and old, line the bottom and sides of his belly. Namjoon tries to ignore the overwhelming urge to take note of which marks are the freshest.
His fleece bottoms are in an even worse state– Namjoon's not entirely sure how Taehyung squeezed himself into them. The bottoms are practically painted onto the bigger man. The drawstring waistband is completely undone, but it still looks like it's biting into Taehyung’s chubby hips. It's a miracle he's able to sleep in such uncomfortable clothes.
Namjoon also takes notice of the two empty pizza boxes left on the coffee table. He sighs, already moving to clean up his roommate's mess. Upon close inspection Namjoon also finds three empty protein shake bottles, two snack cake wrappers, and a half eaten bag of candy. Looks like the younger man had quite the feast while Namjoon was at work.
Taehyung’s lucky he's cute, Namjoon doesn’t clean up after just anyone.
Once the living room is cleaned up Namjoon finally goes to his own room to wash up and get ready for bed. When he comes back Taehyung is in the same position he left him.
“Taehyungie,” Namjoon whispers as he takes pity on the younger man. If he sleeps like that the whole night his back will be sore. “Taehyungie, wake up.”
Taehyung whines in his sleep and goes to bury his head further into the couch.
Namjoon sighs and starts jostling Taehyung’s shoulder to rouse him from his sleep. “Wake up, you shouldn't fall asleep out here.”
After another minute Taehyung finally scrunches his face cutely and blinks his eyes open. “Whathappened?”
Namjoon chuckles slightly at the man's deeply confused slur. “You fell asleep on the couch, big guy, let's get you back to your bed.”
“I'm not-” Taheyung starts to slur, voice heavy with sleep. “I'm not a big guy.”
“Oh I think you are,” Namjoon huffs. “Come on.” He carefully helps support Taehyung to his feet, manhandling him in order to get the younger man to cooperate.
Taehyung’s even heavier once on his feet, almost his entire weight being supported by Namjoon. His knees buckle slightly at the sudden weight, but Namjoon quickly regains his footing. Damn. If Taehyung keeps gaining Namjoon will have to increase his gym routine. No way he'll be able to help Taehyung like this again in six months.
By the state of the living room when Namjoon arrived…it is clear Taehyung isn't losing weight anytime soon.
⊹₊ ⋆
Namjoon eyes the multiple dishes the waitress sets in front of Taehyung. The small space of their table is immediately taken up by the four different plates.
Namjoon counts twelve dumplings, four scallion pancakes, cheesy tteokbokki, and a heaping pile of bulgogi over rice.
Taehyung catches Namjoon staring and flushes. “I was hungry.”
“I can see,” Namjoon responds.
“You know this place has great food,” Taehyung is already picking up one of his dumplings and stuffing the whole thing into his mouth. “I've been thinking about it all day.”
Namjoon simply nods as he watches Taehyung methodically eat his way through his dishes. The younger man barely even pauses in between bites, he's eating as if he hasn't had anything in days– which Namjoon knows is far from the truth.
It seems these days that Taehyung’s default setting is stuffing himself. Namjoon doesn't know the last time he saw his roommate without something to eat…or drink.
Not that Namjoon's counting, but these days Taehyung is up to six shakes a day. Namjoon has never met anyone addicted to protein shakes, but there's a first time for everything. Taehyung is either oblivious to how much he's ballooned (unlikely at this size) or he's simply in denial.
As Taehyung shovels bites of tteokbokki into his mouth, Namjoon has the distinct feeling that his roommate is in deep deep denial.

The door to the apartment slams open, startling Namjoon from his book.
He looks up to see Taehyung struggling to carry grocery bags through the door. Namjoon quickly gets up to assist his roomate– he's been needing to do that a lot lately. Taehyung’s ever increasing size has led to the younger man needing more and more help from Namjoon.
“Thanks hyung,” Taehyung wheezes as Namjoon easily takes all the bags from him.
To his credit the bags are pretty heavy, even for Namjoon. What could possibly be so heavy? He curiously takes a peek into the bags.
“Was the store having a sale on these things?” Namjoon asks, holding up one of Taehyung protein shakes. “Why are you carrying up like three dozen of these?”
“My order was going to be late so I needed some to tide me over,” Taehyung pants. He's still sweating, the beads trailing down his double chin before soaking into his shirt.
“When is your shipment coming? Next week?”
“No in like three days,” Taehyung replies, already reaching into the bag to crack open a shake.
“Three days!” Namjoon exclaims. “You're going to drink all these in three days? Why would you need so many?”
“Because it's a part of my diet. I'm supposed to drink my protein shake whenever I'm hungry.”
Namjoon gives the man a perplexed look. Where on earth is he getting this kind of diet advice?
“Why would you do that?”
Taehyung blushes. “Well, I've been putting on a little weight and I saw a video saying shakes can help you lose weight. The guy said when you feel hungry to have a shake. I've been getting hungrier so I've been buying more.”
Namjoon can't believe what he's hearing.
“Taehyung,” Namjoon starts in disbelief. “Have you been having these with every meal and snack?”
“Yeah…”
Namjoon covered his eyes with his hand, sighing deeply. “I'm pretty sure they meant you replace a meal with a shake NOT drink one with your meals.”
Taehyung gives him a lost look. “But the guy said-”
“I'm sorry but there's no way anyone with any sense would tell you to drink it with a meal,” Namjoon tries to keep his voice level, but Taehyung already. seems to be growing flustered at his words
“But- I…I just followed the video,” Taehyung pouts, his hands fiddle with the bottom of his shirt. Namjoon pointedly ignores the way Taehyung’s tanned belly is hanging out of his 3XL shirt.
Namjoon takes out a shake. Looks like he'll have to explain to his adult roommate how calories work.
He pauses at the bottle, turning the thing around several times before looking at his oversized man in front of him. “Taehyung, is this your usual brand?”
“Yeah, it's the only one I found that tasted good,” Taehyung frowns. “Is something wrong?”
Namjoon can help the near hysterical laugh that falls from his lips. Taehyung hasn't been drinking protein shakes, he's been drinking high calorie meal replacement shakes.
“Yeah something's wrong,” Namjoon takes a second to collect himself. “These are not protein shakes.”
Taehyung cocks his head in confusion.
“You have been buying and drinking calorie dense meal replacement shakes for months. Taehyung, this six pack alone is like 3,000 calories.”
The younger man's face immediately drops.
“I- what? What does that mean?”
“That means you've been accidentally fattening yourself up by adding over 2,000 liquid calories to your diet everyday for almost a year. No wonder you've gotten so big!”
Taehyung’s chubby cheeks burn in embarrassment.
“How much have you put on since going on this ‘diet’?” Namjoon probes. “Don't tell me you didn't notice?”
Taehyung looks away and mumbles something.
“What was that?”
Taehyung clears his throat, eyes darting to Namjoon's before looking away in shame. “About 200lbs.”
Namjoon steps closer. He doesn't even have to look hard to know Taehyung’s gained more than that. He's past chubby, he is downright massive now.
“You want to hop on the scale to confirm that.”
Taehyung’s cheeks burn even brighter with Namjoon's teasing comment. “You don't have to be mean about it. How was I supposed to know?”
“Well, you could've read the nutrition label to start. But I think you enjoyed it.”
Taehyung’s head snaps towards Namjoon, eyes wide and pupils dilated.
“I think you knew you were getting fatter but you just didn't care. You want to keep eating even if it means getting to 400lbs before you're even 30. Is that right?” Namjoon steps even closer until Taehyung's flabby belly is pressing into his own toned middle. “You just couldn't help yourself, huh?”
Taehyung lets out a breathy whine as he feels Namjoon's hand grasp his bottom-most roll and shake. “Hy-hyung…”
The younger man sounds absolutely wrecked. Namjoon couldn't be more turned on now if he tried. The sight of his obese roommate whining sends a wave of heat straight to his dick.
“You can tell me to stop,” Namjoon whispers into Taehyung’s ear.
“Please don't stop!” Taehyung moans loudly.
Namjoon smirks and reaches behind the fat man to pick up one of the shakes. “How about we do this.” He pauses to make sure the younger man is listening. “You are going to chug this whole thing. Then we're going to weigh you…see how much damage you've done. And then finally I am going to fuck you so hard you forget your name. How's that sound?”
“Yes, please hyung.” Taehyung nods enthusiastically causing ripples throughout his fattened body.
Namjoon tips the younger man's head back and lifts the shake to his lips. “You better start drinking then.”
