(This story is set in a garage, I don't know much about cars so please don't get mad if I make mistakes)

The large bear man stands up, brown liquid dripping down his pantleg as his fox wife shakes her head at him, tossing him his jacket "You should get to work soon"
"I know" he says, a frown on his face as he slips his jacket on over his chubby body.

He makes his way out of the door, seeing his son board the bus with a look of shame, him sharing the same look as he opens his car door, closing it behind him while he sits, his shart sticking to his ass and stinking up the entirety of the vehicle,
He spends the next half-an-hour uncomfortably driving along the highway, finally reaching the mechanic garage in which he works, parking outside and waddling to the front door.

"Hey, Gruff! 20 minutes late, what kept you?" The fat bear looks at the muscular bull working on an engine with a wrench "Oh, my son had an accident..." he sighs, the bull laughing "That musta been rank! I know your wife's cookin!" the 2 large men laugh in unison, Gruff hoping his friend doesn't notice the wet mark on the butt of his pants

"Well, we have an old car you gotta fix up" Caz points to a busted car suspended on the other side of the garage "Well, I'll get right to it" says Gruff as he takes off his jacket, grabs a wrench of his own and slides under the car on his back to work on the engine, now in a very compromising position as his belly begins to rumble, a cold sweat runs down his neck as he knows what's about to happen.
He tries desperately to hold it in, but the pain in his belly gets more and more extreme, until finally he couldn't hold it.

He grunts, before releasing a powerful force of hot air from his bottom, smelling like rotton eggs, the extreme wet fart lasts no-more-or-less than 10 seconds, the wet spot on the butt of his underwear grows larger, as more liquid shit drips from his cornhole, he hears (And feels) the heavy footsteps of the Caz walking towards him, followed by a heavy laugh from the bull "Looks like Sox isn't the only one who had an accident today!" He slaps his knee as he continues laughing ever-harder as Gruff attempts to stand up, the mess in his pants making it difficult.

He manages to successfully stand, his nerves and his pride making him anxious as he runs to the bathroom, Caz trailing behind him, Gruff slams through the door 'Damn' he thinks 'I forgot, the bathroom has no stalls, the toilets are in the open!' he decides that it just doesn't matter as he slips his boots off, and then his pants, revealing his big, blubbery, poop-covered butt, Caz busts into the room behind him, getting a good view of his booty.
He sits on the toilet as fast as possible, his stomach makes a loud grumble, before he begins violently squirting into the toilet, pure liquid 'chocolate' making it's wqay out of him, smelling of eggs and milk, much like his breakfast, Caz giggles and keeps watching like a creep, taking in a deep breath, clearly enjoying the show.

After letting out a few more squirts and farts, Gruff stands up, looking down into the toilet at his mess, then to his messy pants, and finally at Caz, he notices a large bulge in Caz's jeans 'Is... Is he getting hard over this!?' Gruff thinks, just before Caz suddenly pulls down his pants, revealing his large bone, he walks towards Gruff and pushes him out of the way, aiming his foot-long dick to the same toilet Gruff had used, and begins pissing into it as gruff stands behind him confused.
Caz then turns around, and sits onto the toilet, he clenches his fist and grunts, as the toilet water beneath him splashes and the smell gets twice as worse, Caz continues to squeeze out more farts and waste into the toilet, adding to Gruff's mess, Caz then ends his show with a grande finale, a massive wet fart followed by 3 splashes in the toilet, He then stands, towering above Gruff, Gruff looks into the toilet, the bowl is nearly overflowing, filled with the pee of both men, Gruff's diarrhea, and 4 massive firm logs that were added by Caz.

Caz then leans against the wall with one hand, and spreads his buttcheeks with the other "Time to clean up, fatboy" He says with a laugh...
