"Oh thank you so much, Spike!" called Fluttershy as she raced out the door. "I'll find some way to make it up to you, I promise!" The door to the classroom slammed shut behind her, and Spike was left in the front of the classroom, alone.

The young drake cleared his throat. "Alright then," he said. "Um, let's get started I guess." He turned towards the chalkboard at the front of the room, pausing for a moment before turning back to the class. "Uh, what was it you guys were learning?"

"The equine endocrine system," muttered Gallus in a bored tone, leaning back in his seat. Spike got to scribbling notes on the board from the lesson plans Fluttershy had left him, and the remainder of the class slowly glazed over.

Gallus felt a hoof poke into him from behind, and he turned to face Sandbar. "Where's Yona?" asked the tan pony, gesturing to the empty desk a row away.

The griffon just shrugged and replied, "I dunno, maybe she's pregnant." Sandbar blushed at the implication and Gallus chuckled. "Oh come on man, she bangs that quiet farmer dude like every weekend." Sandbar just leaned back, embarrassed by the blatantly explicit nature of the talk. "I heard that guy's cock was massive!" The pony just shook his head at the crass griffon and focused back on the board.

Spike was doing his best at drawing the innards of a pony, standing on his tiptoes atop a stool. The chalk scraped against the board as he drew squiggle after squiggle, ending in a crudely drawn star representing an anus.

"Oh come on," whispered Gallus. "That is not what a pony butthole looks like!" He laughed, trying to keep his voice down.

Sandbar shushed him, nodding his head towards the board. "Just pay attention, there's a test on Monday!" he whispered back. He just did not understand how some creatures could be so flippant about the studies.

The griffon leaned over in his desk, wriggling his eyebrows at Sandbar as he whispered, "What's the point if he's teaching us wrong huh? Why don't you help me out and show me that cute little pucker of yours?" He winked at the young pony. "Maybe get some up close lessons on your waste removal?"

Sandbar blushed a deep shade of red at what Gallus was implying. Sure, it was not unusual for everypony to relieve themselves as necessary, whenever and wherever, but there was something innately private about deliberately doing it for somepony else. He wasn't completely obvious, he knew that most ponies got a perverse pleasure out of relieving themselves together. However, it seemed a bit too sexual for his tastes.

"I can see those gears turning, Sandy Boy," Gallus jeered. "Do it. Right here. Right on the floor next to your desk."

"Do what?" Sandbar hissed back.

With a crude grin, the griffon pointed a claw at the ground. "Shit."

The earth pony let out a huff of indignation. "Really? In the middle of the classroom? No." He lifted a hoof and pointed to the rear corner. "If I needed to go, which I don't, I will go in the corner like everypony else." As if on cue, his gut gave a quiet gurgle, making Gallus laugh as the pony clutched his stomach.

"Are you sure you don't need to pinch a loaf?" Gallus asked. "What's stopping you?"

The griffon was right, Sandbar admitted to himself. There was no real rule preventing him from simply doing his business by his desk. It was just out of common courtesy that everypony else went to the back corner to do it. But still, he wasn't going to just drop a deuce in the middle of the damn classroom!

"I dare you to," goaded Gallus with a sly smirk, seeing the indecision on Sandbar's face.

"Ugh!" groaned Sandbar, slamming his head into his desk. "Fine, you win. I'll poop for you," he conceded, immediately regretting how the words tasted.

Gallus laughed. "Hot! Let's do it!"

Rolling his eyes Sanbar slid out of his seat, positioning himself next to his desk. After getting a thumbs up from Gallus, he lifted his short tail and squatted. A few seats behind him, he heard Smolder stifling laughter, and he shot her an angry glare. She too simply gave him a thumbs up whilst covering her mouth with her other claw.

Trying to ignore all the attention, the colt closed his eyes and tried to concentrate. His gut rumbled, and his butthole quivered, a small pocket of gas hissing out. The pucker opened up, and the head of a soft turd poked out. It snaked out of the young colt's ass, and slid to the floor, coiling in a small pile.

A motion off to his side caught Sandbar's eye, and he looked over to see Gallus gripping his hard cock in one claw, stroking the shaft up and down as he watched Sandbar take a shit. The pony balked as he watched his classmate openly masturbate. "Gallus!"

The griffon didn't reply other than to wiggle his stiff member at him with a cocky grin. Rolling his eyes, Sandbar pushed again, trying to get the next log out. The tip of the next log started to slide out, and then rapidly picked up pace. A hiss of crackling gas escapes with it, quickly rising in volume until the end of the soft turd shot out of his ass with a wet, splattering fart. The soft shit impacted on the tile floor with a dull splat, while the rest of his gas wheezed out of his loose pucker with a wet sharting sound. Unable to stop it, a third piece of crap began to slip out after it.

"Oh! What a great idea Sandbar!" Spike's voice rang through the classroom, and the colt's anus clenched, abruptly cutting off the log that was slipping out. All of the eyes in the classroom were on him, with every creature there alerted to his actions by his boisterous flatulence.

"W-what?!" Sandbar stammered, quickly straightening up. He attempted to sweep his excrement under his desk with a hind hoof, but he cringed as the soft poop instead smeared across his hoof and streaked on the tiled floor. Smolder burst out laughing behind him at his mistake, and his cheeks flushed red with embarrassment.

Spike climbed up onto the teacher's desk, and gestured for Sandbar to walk forward. "Why don't you finish pooping up here, on the desk? That way we can add a demonstration to the lesson!" The young dragon looked incredibly proud of himself, as if this was the best idea he had ever come up with.

"Oh, um, I don't think-" Sanbar began, but he was quickly shushed by Gallus smacking his flank.

"Go and get 'em, guy!" the griffon cheered with a wink.

"Yeah! Go shit on the desk!" Smolder echoed from behind him. Soon, every creature in the classroom was cheering for him to get up on Miss Fluttershy's desk and poop. Blushing madly, and quickly caving in to the peer pressure, Sandbar took a few hesitant steps forward towards the front of the classroom. His hind hoof squelched with each step, uncomfortably reminding him of the smeared crap attached to it.

Spike moved off to the side when the colt hopped onto the wooden surface. Sandbar noticed with embarrassment that the young dragon's barbed cock had slipped out of it's scaley sheath, and was throbbing on full display. Looking out over the classroom, he noticed that Gallus had resumed his masturbating and that Smolder had also joined him. The orange dragon had her legs spread wide on top of her desk, her young pussy on full display while she slowly fingered it. Was every creature in this room aroused by his bathroom break?

At Spike's insistent gesture to turn around and get going, the colt did just that. He turned around, presenting his flank to the class and flipping up his tail. His already dirtied and smeared anus was bared, and he lightly squatted to resume pooping. A quiet fart slipped out of his butthole, before it widened to accomodate a fresh log. Soft clumps of digested hay slid out, plopping into the desk. The class watched in interest, with several other students growing aroused at the display. As the last of his horseapples slid out, Sandbar let out a final, wet fart, his butthole vibrating with the expulsion of anal air. He pushed on his rectum a few times to make sure that all of his poop was out, before straightening back up.

With his bowel movement complete, Sandbar turned back around to face the class. He face was flushed with shame and embarrassment at what he had just done, but he could not deny that he was definitely feeling slightly aroused. His adolescent cock had slipped out of his sheath, and while still flaccid, was swaying between his legs. The smell of his fresh shit between his forelegs wafted up into his nose, and he found himself eagerly trying to breath in the fetid stench, whilst still trying to remain subtle about it.

He looked out over the class, trying to gauge their reactions. He had managed to turn around just in time to watch Gallus grunt as he came, rapidly stroking his cock as jets of white griffon cum erupted out of it's tip and sprayed all over his down and desk. A particularly powerful shot nailed him right in the jaw, and Gallus shuddered in the afterglow as he stick out his tongue to lick it up. A few seats away, Smolder was licking her claws clean of her own feminine juices, and she winked at Sandbar as their eyes met.

"Well, ahem, good job," commented Spike beside him, and Sandbar turned to look at him. He was only slightly surprised to see that the dragon's penis was throbbing painfully, and his purple claws were doing a valiant job of not grasping the draconian cock and stroking it away into oblivion. "Now if you'll step aside, we can, um, compare it to the, uh, waste of another species." Spike shooed Sandbar off of the desk, and the young colt found himself watching with a strange interest as the dragon turned and squatted over the pile of poop.

His thick tail flipped up and his scaly anus was presented to the class. It was caked with scat from past trips to the bathroom, and Sandbar cringed as he saw it. Did no pony besides him have any sense of proper bathroom hygiene?

A log of shit poked its way out of Spike's butthole. It was much harder in consistency than Sandbar's, keeping its form as it snaked out of the dragon's ass. It reached a good length before it slid out completely, dropping with a dull thud right on top of the pile of pony poop that Sandbar had left behind. Another dry fart crackled out before the head of another turd made an appearance. This one was similar in texture, but it slipped out a lot faster, only taking a few second to exit Spike's rectum and drape itself atop the first log. Spike's anus flexed a few times, smearing the fecal slime left behind in it's wrinkles before he stood up, apparently having finished.

"Now," Spike said, turning back around, his turgid member flexing slightly as he caught a whiff of his own waste mixed with Sandbar's. "As you can see, the two different defecations have very different consistencies." He glanced over Fluttershy's lesson plans again before continuing. "This is due to differences in diet, digestive system-" The dragon's voice droned on as the rest of the class quickly lost interest.

Sandbar took one last glance at their combined piles of poop before walking back towards his own desk. Gallus gave him a thumbs up as he approached his desk, and the colt rolled his eyes with a blush. Something squished beneath his hoof as he went to slide into his desk, and he cringed as he realized that he had stepped in his own shit again. Gallus and Smolder stifled their laughter as they watched him sit in his chair with a frown, bringing his dirtied forehoof up to his nose to sniff at the offending muck.

Suddenly, Smolder was beside his desk, squatting slightly over his smeared mess of shit that he had left behind earlier. She placed one her claws on his thigh to steady herself, noting with satisfaction as his hard dick twitched at her proximity. With a sigh, she released, and Sandbar watched as a spray of dragon urine streamed out of her pussy, splattering onto the ground below.

The acrid fluid mixed with his poop, and Sandbar's nose twitched as the offensive odor reached his nose. Dragon urine was much stronger than pony urine, and it's acidic stench was foul. However, he found that he didn't quite mind it all that much. Unable to help himself, he sniffed at his dirtied hoof. His cock was rock hard and throbbing now, and he gave into the temptation to grasp it with his hoof. He gave it a few experimental strokes, quickly giving in to full-on masturbation as the pleasure soared through his groin.

His hoof was pushed away from his penis all of a sudden, and he looked down as Smolder replaced it with her claw. She slowly jerked him off as she finished pissing. He tensed up before relaxing into the sensation. He quickly approached his climax, closing his eyes and sighing as spurts of thick colt cum squirted out of his tip. The sensation around his dick switched to something more slimy and warm, and it only added to his pleasure as he came. He sighed as he leaned back, twitching cock slowly softening in Smolder's grasp.

The sound of chuckling and stifled laughter beside him caused him to open up his eyes and look at his friends. Gallus was doing his best not to explode with laughter while Smolder was softly chuckling with a blushing face. She waved at him, her claw smeared with her piss and his shit.

Suddenly putting two and two together, Sandbar looked down at his lap, and let out a small groan as he realized that his penis and balls were covered in clumps of his soft creamy scat and her warm urine. Strings of his warm cum draped over his chest and dripped down onto this cock, adding to the ensemble. The smell of the mixed substances drifted up to him and tingled his nostrils. Bashfully, the colt admitted to himself that he wasn't really all that upset by the development. If anything, the knowledge aroused him more.

He did not know if that was for better or for worse.
