#sub training gone wrong

He chose a sweet, tiny hybrid with fluffy ears. He was half… no, a third of the size as Jungkook. Not that it was a fair comparison. Most people were a third or at least half of Jungkook's size. But this hybrid was honestly miniscule; it wasn't just Jungkook being fat.

His name was Yoongi, a cat hybrid about his age, with black hair and fur, and big curious eyes that stared at Jungkook as they held hands walking towards the human's car; which Jungkook had begun to outgrow just recently…

Jungkook’s face was flushed when they finally arrived at his car. “Well, you can get in the back.” Yoongi nods softly, wide eyes trying to figure out how the door works. He’s only seen cages, really. The human watches, amused.

"Like this." He opens the door for him and Yoongi's eyes widen a bit, staring at Jungkook as if he had done something magical; before eagerly crawling inside. The second he closed the door, the kitten's ears would flatten in fear. Jungkook will come to find, Yoongi will need a lot of reassurance to not fear his possible abandonment.

He gets in the front, taking them home with ease. Yoongi’s enamoured. He looks around, staring at all the lights that blink around him.

And from then on, one could say Yoongi adapted easily to life outside of the refuge, a small family with Jungkook as his doting owner. He took all the measures he had researched about, from familiarizing Yoongi to his scent, to picking out blankets and clothes that were friendly to sensitive hybrid skin, being gradual with his touches as to give the hybrid the space he needed. But it seemed like none of that was necessary, because Yoongi adapted amazingly; curious but relaxedly getting to know Jungkook’s apartment, loving and seeking the attention from his owner.

If anything, it was Jungkook the one struggling to adapt to the kitten...and his stamina

Jungkook would be relaxing on the bed, body soft. Jungkook never really closed doors anymore, since yoongi would just sit, meowing in front of it. Since… he didn’t really understand how it opened

And Yoongi's meowing could only mean one thing. He wants to play.

Jungkook really didn't consider that the cat hybrid he adopted would be anything but cuddly and peaceful. Let alone having to stand up from where he was laying down with a tired huff, and waddling over to the living room where he would play with Yoongi. Reminding himself that it wasn't advised to neglect your hybrd while still in the beginning of forming a bond with them.

Jungkook would pant pathetically, face red and sweaty, waving the little string-like toy for Yoongi to catch. He'd plop himself down tiredly on the couch, but it was futile to be a play buddy that way; Yoongi's whines always forcing him back to stand.

Jungkook grunts as he sits back down, panting more and spreading his thighs. Yoongi looked up at him curiously, staring , surprised at how red Jungkook got. But he still whined, begging for more play. Jungkook would listen of course... the tiny kitten pleading so sweetly that Jungkook would rather lose at least ten kilos than none.

Well, perhaps that was an exaggeration.

As his heart dropped to the floor when he realized he had lost almost 5 kilos in this month he had Yoongi. And realize something had to change. Of course 5 kilos didn't look like any difference on a body this big, but what was going to become of him if he kept this rhythm up?!

It was time to try and finally train his kitten.

Jungkook sat in the bed, Yoongi whining on the floor next to him. “Play...” He pouts, squirming and tail whipping behind him. “Ma-master, play…”

He had to clench his chubby fists to try and control himself from giving in, Yoongi's eyes wide and bottom lip puckered out, sat kneeling with his bum on the floor and thighs spread. Black tail swinging behind him, predatory almost; if it wasn't for how far he was from looking threatening.

"Yoonie, it's getting late, it's not play time." The kitten's frown deepened, and was about to open his mouth to complain again, but Jungkook acted quickly and perhaps recklessly. Grabbing from the cookies he had been snacking on, bringing one to Yoongi's lips. "Here you get a treat for resting when you're supposed to."

It would be the first human food Yoongi had ever tasted.

He gasps, feeling the sweet flavour on his tongue. It’s amazing… it sends shocks to his tail and ears that makes him spasm. Jungkook smiles, watching Yoongi nod quickly and climb onto the bed, curling to his side and nibbling on the cookie.

“Good boy. It’s rest time, okay?”

And... Jungkook didn't mean ifor it to get out of hand okay? But after that, Yoongi started behaving, settling down; but always with the condition that he'd get a prize in return. Which could only be whatever human food Jungkook had at his grasp at that moment.

It was fine at first with things like snacks and cookies because they are different from the actual meals Jungkook ate while Yoongi sat next to him eating his hybrid food.

But once he got a taste of Jungkook's pizza that one time, it was when it really got out of hand. Since he'd start begging Jungkook to cut the hybrid food and start feeding him the food he ate!

Jungkook would smile softly, agreeing with his sweet boy; unaware of what it would cause. “Of course angel…” Yoongi began eating with Jungkook, giving him the full meals that his owner had. The food tasted so much better than hybrid food.

Jungkook didn’t really notice the changes to Yoongi’s body - focusing on how much calmer he appeared to be. Instead of begging to play, the hybrid would climb up next to his owner, cuddling his fattened side and nuzzling into his neck. Rubbing his nose gently over the soft skin. Scenting him, Jungkook had researched. As the kitten tried to envelope as much of his large body in a hug, leg sinking gently over his stomach and torso pressed against his thigh.

And Jungkook is so big, of course it would be hard to register any changes in his hybrid’s body . Any amount of weight gain looked small in comparison to him.

But it wasn't only that, Yoongi's habits began to morph in the image of Jungkook's. The overeating, the napping, the bloating. It became a daily routine that after lunch Yoongi would sit himself on Jungkook's lap, stomach rounded out and protruding outwards in what Jungkook assumed was only a bloat, and he'd rub the sting away. With a completely relaxed and melted hybrid lying across his chest.

Yoongi would purr so loudly that he’d become a little hazy, cooing softly at Jungkook's softness and softer touches "I like this" He'd mumble in a low voice. His vocabulary having expanded since he started living with Jungkook.

"It gets less uncomfy the more you do it." Jungkook comments before grinning. "And you've been overeating a lot lately, kitten" he mumbles fondly before kissing the side of the hybrid's head.

Yoongi giggles softly, nuzzling closer and ignoring what Jungkook said. He understands almost everything, but some things were better left unexplained.

Yoongi purrs, blissed by the sheer softness and Jungkook smiles. “Maybe you’ve been extra good.”

Yoongi's ears perk up. “Treat? Do I get a treat?”

"Wasn't I just rubbing your belly from overeating?" He raises a questioning eyebrow.

"....But you said I've been extra good." He was getting more clever these days. Even if it only happened when it was convenient to the kitten.

And by this point, Jungkook had given up all resistance. Spoiling his kitten, grinning as he hand fed the candybar to Yoongi. Who was more than happy to eat, practically melting on Jungkook's lap.

This routine continues, every night, stuffing his body to the limit and feeling nothing but relaxed joy when his owner would snuggle into him. Cuddling together every time Jungkook wasn’t working, or that they weren't eating. He feels embarrassed it took him this long to notice...

He had fattened up his hybrid.

It was like he was seeing it for the first time when he walked out from sleeping with clothes that barely clung to his body. Shirt worn like a tank top, belly overspilling from underneath; shorts cutting low into his plush hips, and that hugged his legs uncomfortably.

How did he not notice sooner?

Jungkook gave him some of his own clothes and that would suffice. He still swam in those.

He swam in them for now.

His owner was far from making him exercise. They both loved eating and Yoongi’s appetite was only growing. Jungkook pets Yoongi's hair lovingly, smiling softly as the smaller one purred happily; watching yoongi’s fattier tail lull lazily side to side.

Everything about him had become lazy. The kitten spent most of his days sprawled on Jungkook's bed, the sunlight hitting just right for him to stay there. Only getting up to eat or to cuddle alongside his master.

Even if it was accidental, Jungkook can't say he minds this transformed version of his once hyperactive kitty. So lovingly cuddling on his lap, bellies pressed together, chubby arms wrapped around each other, as Jungkook massaged the base of Yoongi's tail; making the hybrid melt.

Yoongi wouldn’t ask to play anymore instead, asking for more snacks. He really couldn’t be bothered to think of playing anymore. He was so lazy.

"What's that?" He heard a voice behind him in the kitchen, and Jungkook didn't have to turn to know. He was just pouring some of the heavy cream into his own cup, grinning as he looks over his shoulder.

"Heavy cream, Yoonie. Why?" He knows exactly why. But he wants to hear the kitten ask for it.

Yoongi's hands are wrapped around the black tail, pressing it to his chest as if guilty. "Can.... I have some?"

Ah, perfect. "Why are you suddenly interested? I don't remember ever giving you some." He questions as he pours more of the thick liquid into his own cup.

"I mistook it...for milk....but it was better! "

Jungkook laughs, leaning to get Yoongi his own cup. “Come here kitten, There’s only a few drops left.” He pours barely a splash, giving the cup to Yoongi.

He takes it happily, gulping the very small amount down in a mouthful. And widens as if it were the first time trying it all over again. Beaming and licking at his lips eagerly mewling at the flavor. Hands into fists from how good it was. "Aw, you really liked it, didn't you?" Jungkook is too endeared, heavy hand cradling through Yoongi's soft hair.

He coos as Yoongi nods quickly, smiling and giggling. “Can I have more?”

“Baby there’s no more.” Jungkook smiles, drinking from his own cup.

Yoongi’s smile turns into a pout, chubby frame deflating, before it perks up again.... looking at Jungkook's glass.

"Can I have some of yours?" He rephrases and Jungkook feels himself grip a little tighter into his glass.

“No kitten...” Jungkook smiled weakly, resolve weakening. “I’m not giving you my cream.”

Yoongi giggles softly, reaching for the glass greedily. “Master~~ please, please?”

"Y-yah you should've told me you wanted before I poured a glass." He complains softly yerking the glass away from the soft hand from the kitten trying to snatch it away. Jungkook is lucky the gluttony slowed down any fo Yoongi's remaining hunting instincts.

"But you could share!!"

“I already shared, piggy.” Jungkook laughs and Yoongi freezes. He doesn’t know what piggy means so he tilts his head.

“Master… I want it” Yoongi pouts again and Jungkook sighs. He gives the plump kitten the cup.

Spoiled, spoiled pet. Jungkook thinks to himself, as Yoongi's eyes lift up. "You should be careful, though." He says as the cat was already excitedly bringing the tall glass to his lips. "This could settle pretty heavily on you if you're not used to it." He says but it looks like the kitten won't listen.

Yoongi gulps it greedily, groaning happily behind each mouthful.

“Baby, slow down.” He chuckles, soothing his hair and kissing his nose. “It’s heavy cream. It’s going to feel gross for a bit.”

Yoongi shakes his head in disagreement "Not gross! Yummy!" He says before taking another gulp. And Jungkook can only sigh, as he sees the kitten gasp for air before setting the glass down.

The heavy cream settling in, just like Jungkook predicted.

Yoongi whines sweetly, pouting up at Jungkook with cream around his upper lip. “…W-why so full?” He pushes up closer - bloated belly in need of attention.

Jungkook chuckles.

"You should have listened, kitten." He scolds but it has no bite to it, how could it with Jungkook's loving tone and the way he wraps his arms around the hybrid? Pressing Yoongi close to his side, as the hand rubs at the side of his belly. "Let's get you to the couch, yeah?"

Yoongi nods pathetically, staring softly up at Jungkook as they both waddle slowly to the couch. He knows how fast Yoongi's appetite appears again. So now snacks are stocked all over the house… like before, just in high quantities.

He isn’t eating alone anymore.

Jungkook tried to lay him down gently, but neither his or Yoongi's weight would allow that. They plop down onto the couch and while Jungkook is used to it, the cat hybrid whines, cupping his full rounded belly in discomfort. "R-rubs, I need rubs" He mumbles weakly.

And like most times, Jungkook is quick and happy to comply, cooing softly. “You’re very full, kitty. You’re so so cute.”

Yoongi's eyes close, eyebrows scrunched upwards cutely, as he nuzzles further towards Jungkook. Tail curling over to "hug" the bigger man as well. "That's it, Yoonie. You drank it all! You're turning into a bit of a piggy aren't you?
