As it roared and gurgled, Eevee's lower abdomen was starting to become exceedingly bloated. Her sisters' concern grew larger; they were very aware of the fact that the smallest thing would set off a massive, noxious gas-nuke. Their worry soon transitioned into fear, terrified of being caught in the blast; some of the eeveelutions took a few steps back.
Suddenly, Sylveon--who, much like the others, was keeping her distance--spoke up. "Eevee, s-stop! You're going to hurt yourself if you keep that up!" She said, with somewhat of a trembly voice. "...A-And, most importantly--you're going to intoxicate us if you let that out in here!!"
"Pft... gh... I'm fine" Eevee responded, amidst pained groans and sighs. "In fact... URRPP!~ ...I'm feeling kind of hungry... gh..." She continued, getting up from her resting position and slowly waddling over to a small alcove of the burrow in which the eeveelutions kept the food.
Everyone watched speechless, baffled by their sister's actions. Soon, Eevee was right in front of the food pile, filled to the brim with different berries. Without hesitation, she started eating them aggressively, splattering juice all over the walls and herself; but, most importantly, she had blown the last hit to her stomach. Her guts let out the loudest roar so far, and with it came intense cramps that made Eevee experience an amount of pain she had never experienced before, however, the amount of satisfaction was a worthy rival; it was, indeed, painful, but Eevee was experiencing her two favorite things at the same time: feasting on food and swelling up with noxious gas.
Her cramps were getting worse and worse, to the point in which she could barely keep herself standing. Her sisters were shouting at her, telling her to stop, but still too afraid to come close. Eventually, she grew exhausted, laying on the ground as her rump sticked out . Sylveon quickly stepped closer, worried. "H-Hey!! Are you--?"
...prrrt!~
A small puff of gas escaped her cute butt, as her tail began to twitch and rise. Everyone went silent. "I've... hah... I've reached my limit..." Eevee said quietly, panting. "Hah... hahah!,"
bbbRRrt!~ prrrRRT!!~
"SHE'S GONNA BLOOOW!!!" Umbreon shouted, as chaos broke loose in the burrow.
Eevee had finally reached her limit, and a catastrophic amount of foul gas was about to engulf her sisters, the burrow, and all of the surrounding area. However, there could be a way to minimize the damage, or to even keep it from happening...
