A/N
This is a random idea, after having a daydream involving chubby minions, so one thing led to another, but now decided to do a Kave story out of the idea, but not smutty.
After testing the Gut Grower on them, Dave and Kevin's metabolisms are altered for good, meaning they are growing bellies but becoming Chibby and cute which should be fun plus they're immortal, so growing more should be fine.
I know the Gut Grower will work, but I need somebody to test it on.
"Ooh what do you think this does, Kev?" Dave asked, making Nefario grin, as Fave and Kevin would be perfect to test his new invention on, plus minions and purple minions were immortal so they could handle more furry meat on their bones.
The Gut Grower altered the metabolism of whatever it's beam hit, meaning slow weight gain, so hoped it would work, seeing both Dave and Kevin stand in front of the machine as it activated, as the beam shot out, hitting both their stomaches, altering their metabolism, but it was tickling them, making them laugh.
After the machine turned off, Nefario grinned seeing both of them really hungry, just wanting to eat and eat, about to head to the kitchen, but Nefario had treats here in the lab, seeing them eat as they just wanted nothing but bananas and sweet stuff.
After a while, they felt really, really sleepy, makimg Nefario grin, as that was a food coma and it would be normal for the both of them, now they were growi
"That's normal for you two now, plus in a few months, the chubbiness will be noticeable." Nefario said, while they were out like lights as he wad wrapping a blanket aroubd tbem, as they were sleeping but also being lazy would help their bellies grow more.
Gru smirked, seeing Nevario had tested the Gut Grower on Dave and Kevin, knowing in a few months they would be very cute, plus those two had their own apartment, and very cute together so knew that they would be alright.
After waking up from their nap, Botn minion males were thirsty, so had found a bottle of Pepsi in the fridge, drinking it, feeling that tickling sensation, meaning their bellies and new chubby frames were growing, high fiving and belching.
"Yes, our bellies are growing more and in a few months, we'll be cute, plus use our bellies like cushions!" Kevin said happily since being a purple minion, he would grow one faster because purple minions were bottomless pits when it came to food, so he could help Dave grow too, plus wanted to sit on Mel if he teased them, making Dave giggle hysterically, finding maple syrup.
"Bottoms up, Davey, hehe!" Kevin said as they drank, because they were not full, so felt the tickling feeling happen, because their chubby new bodies were loving this, plus wanted to use the Gut Grower on their friends, as Nefario said they could but would wait, just in case belching going home to their apartment, taking the Growth ray, so they could make the apartment bigger.
When they got home and made everything bigger, they were sleepy so crashed on their larger couch, because Nefario told them that being lazy would also help their chubbiness grow, which they could not wait for, taking an nap dreaming sweet dreams about a land full of sweets and being chubby.
