Sox stumbles into the foul-smelling school bathroom, passing by an older horse boy who is exiting, the 9 y/o foxboy waddles towards the far end of the dank dark room and to the last stall and hoping that nobody is in there, stepping over a yellow puddle as it splashes up on his leg, but he doesn't care.
He enters the stall as his bladder throbs with pain, slamming the door shut as he slides the lock closed, quickly dropping his shorts to his ankles and sitting down on the porcelain throne, the cold glass pressing against his near-pubescent butt, his tail floofing over the back of the seat, he pushes his pointer-and-middle fingers against his 2" chode and aims it into the bowl, releasing the floodgates as hot yellow piss sprays out, the water bubbling as the high-pressured urine splashes into it, letting out a relaxed sigh as he leans back, his stream nearing it's end.

His belly audibly bubbles as he loosens his muscles, giving a content smirk before his pink butthole twitches open, a handful of hard rabbit-like turds dropping out 'This can't be it' he thinks 'There's no way this is the end' and before this though can end he feels a great fire in his gut, quickly shooting up into a dutiful posture as he lets out an echoing wet fart, the wet smell of the room being replaced by the toxic sent of his bowels, a small spurt of diarrhea squirting out as a thick snake of soft shit slithers out of his pucker, 2.1/2" thick as it falls out, wet residue sticking to his butthole as the pile of softsurve shit piles under him and fills the drain, the end result being at least 9", but the growl in his belly is a damning sign that this isn't over...
...He leans to his left, raising his right cheek off the seat as he grunts, farting loudly while raw liquid shit spews out of him, painting the inner wall of the bowl and some pouring onto the floor, he moans as the boiling river continues to brown the toilet water, until it looks akin to thick creamy coffee, his nose stinging from the smell of his own squirts.

He giggles, the feeling of bubblegut finally passing, but just as he's given a second of recourse the bell rings "Fuck, there's no time!" He whispers to himself, pulling up his pants as he quickly stands, leaving the room without wiping or flushing.
