"Ooooh, slob-mix~! There's always scien...

    by: Unknown
Finn didn't like the way Peebles was looking at him as she took her notepad to a lab station lined with chemicals. She hummed a tune to herself as she mixed some of them together to create a green, bubbly substance. She poured it into a vat where the mystery mixture Finn currently swallowed down was located, both watching the substance in the tube change color. Immediately Finn could taste a strange new sickly sweet flavor enter his mouth, making him moan in delight.

"This stuff is mathematical!" Finn thought, closing his eyes in ecstasy as he embraced the substance entering his mouth.

That is until he heard his stomach churn and gurgle. Bubblegum giggled eagerly as she waited for the chemicals to take effect.

PFFFFFFT!

Finn blushed bright red as he released a horribly nasty fart right in front of the princess. She didn't seem too upset however, looking more aroused if anything. "Oh Finn~ You nasty boy!" the princess cooed as she grabbed a handful of his fat,"are you feeling a little gassy?". She teased him a bit more whilst writing down the results, taking a break once in a while to ogle him. The hero tried to hold in his gas, clenching with his few remaining muscles to no avail, blush becoming a crimson red as he felt his torrent of farts cause his colossal thighs and buttcheeks to jiggle and ripple.

"Oh grob can this even GET any worse" Finn whined, wishing that his gassy outbursts would finally stop. Bubblegum however was taking in as much as she could, bending underneath the hero as close to the source as possible and taking deep, long whiffs of it. Soon he started burping too, which managed to slow down the amount of the solution that came into him momentarily, but not for long.

"Oh glob" Bubblegum exclaimed after Finn released a rather eggy fart and belch at the same time,"there's only one thing I love more than a fat boy stuffing his face.". The Princess walked over to Finn's face, putting her mouth up to his ear and whispering "and that's when they start getting gassy beyond belief. Being insanely fat is one thing, but to rip one without any guilt is such a turn on~."

It was hard for Finn to believe that Bubblegum was finding this hot. In a last ditch effort to escape he struggled once more, which met with no success and only caused even more gas to erupt from him. While Finn continued his inner debates about the situation, Bubblegum stared in awe and arousal at the mound of fat before her. His belly was sagging off the edges of the table and was close to touching the floor, his moobs were getting bigger than her breasts, his legs and arms were practically sinking into his fat, and each butt cheek was the size of a bean bag chair. He was completed naked save for his underwear much to her disappointment, but it would probably snap off soon enough. Finn's belching and farting had also increased much to her delight.

"Such progress, wait right here handsome while I go get a camera to document this." She kissed him on his flabby cheek and left the room. Finn was now blushing as bright red as a beet as he continued to burp, fart, and chug down the liquid.The table continued to creak louder under him and would most likely break at any moment. Finn wobbled in an attempt to break free but ended up releasing enough gas from...

You have the following choices:

*Pen*
1. His burps to blow the tube out of his mouth. . .

2. His farts to destroy his underwear, leaving him naked. . .

*Pen* indicates the next chapter needs to be written.
