Contains M/F, Monster Rape, "Bad-End", and an "It was all someone's D&D campaign" ending so none of this actually happened. But it's MLP fanfic, so it really never happened either way.

What could possibly go wrong?

Deep in the monster-infested wilds of the Everfree Forest, six brave adventurers forged a path through the undergrowth. Not many ponies would dare to venture to such a dangerous place, but these were no ordinary ponies. These were the Elements of Harmony, a bold party of adventurers who laughed in the face of danger!

This deep in the forest, the thick canopy kept the forest floor in a perpetual state of murky gloom, but the party's beautiful sorceress, Rarity, lit the way with a crystal-tipped wand. They had been hiking all day, searching for a nearby dungeon. Zipping back and forth from the front of the group to the back with lightning-fast speed, their rainbow-haired rogue voiced her discontent. "Seriously, Twilight? You want us to clear a dungeon filled with Diamond Dogs? You don't think that's just a teensy bit beneath our skill level?"

Dash twirled her enchanted throwing knives in the air. While Applejack, a fighter, was their party's only tank, they were more than up to the task of bashing some Diamond Dogs. While the monsters flung themselves uselessly against Applejack's shield, everypony else would blast the rotten curs with ranged attacks, hurling spells and shooting missiles.

Twilight adopted her typical wizardly "I'm going to lecture you now" posture as her pseudodragon familiar, Spike, clambered onto her shoulders. "It doesn't matter whether we're over-levelled, Rainbow Dash. We're doing this to help the villagers, not because it's a challenge. These Diamond Dogs have been kidnapping mares from the village for weeks, no doubt to make them toil in their jewel mines! It's our duty as adventurers to defend the weak and helpless throughout Equestria. That's what the magic of friendship is all about!" Pinkie Pie strummed a heroic chord on her lute to underscore Twilight's speech.

Fluttershy, the party druid, practically hid in the confines of her cloak as she worried, "Oh, maybe if we just ask politely, they'll give the kidnapped mares back! I'd hate to have to fight anycreature."

Rarity scoffed, "Fluttershy, you're much too forgiving! These horrid beasties are going to get what's coming to them. No doubt those brutes have been simply monstrous towards these poor damsels in distress!"

"You don't know that, Rarity! Maybe they just wanted to have a party with them and were too shy to ask," Pinkie Pie chirped, skipping ahead of the rest of the party while strumming her lute.

After a few more minutes of hiking, the party picked up a trail. They followed a set of paw prints to a dank, dreary dungeon. A rocky cave entrance was sculpted to look like the hungry jaws of a dog. Applejack hefted her war hammer and shield, testing their balance. She had no doubt that the Diamond Dogs and the missing maidens would be inside.

Twilight Sparkle organized the party as she usually did before they raided dungeons. "Applejack, you stay in front to keep the enemy away from us! Rainbow, Pinkie, you keep behind her and use your knives and bow. Rarity and I will stand further back and give magical support, and Fluttershy…"

The whole party looked at the druid as she cowered behind a rock.

"Um...Fluttershy will take up the rear."

It was a perfect formation for clearing a dungeon of monsters. Without magic of their own, the Diamond Dogs would be powerless. Everypony took up their positions and readied their weapons. Applejack confidently puffed her armored chest out as the party followed her into the dungeon.

"These monsters don't have a chance!"

Never Split the Party

Applejack groaned, clutching her head as she regained consciousness. What had happened to her? It felt like her skull had been bashed like a gong. Judging from the dent her fingers found on her helmet, that wasn't far from the truth. The last thing she remembered was going into the dungeon, and then...something had gone wrong. She recalled a flash of sickly green magic hurled at the party, but that made no sense. Diamond Dogs couldn't cast spells! Slowly, her senses came back to her.

*Glrckk* *Gluk* *Ghuuk*

Somepony was choking! Alarmed, Applejack opened her eyes. It was hard to make anything out in the murky darkness of the dungeon. It took a moment for her eyes to adjust to the dim light. Slowly, her vision came into focus, revealing the source of the noise. Her breath caught in her throat when she saw what had become of her party.

Rainbow Dash was on her back, splayed out on a stone table. Her enchanted daggers were placed well out of her reach. Hulking over her was a massive, shaggy Diamond Dog. It pinned the rogue down by the throat. Dash's unrestrained arms and legs flailed, uselessly beating against the monster. The feeble strikes did nothing to make the brute release its grip. Its massive mitts held her head in place, but that wasn't the source of the choking noise.

To Applejack's horror, the Diamond Dog's red, swollen cock was lodged in Dash's throat. The canine cock pulled hot, sticky threads of spit from the rogue's esophagus. Applejack yelled out, "Rainbow!" Her friend tried to turn her head to look towards the warrior, silently pleading for aid, but the monster picked that moment to slam his hips forward. With an ear-splitting howl, he came in the rogue's mouth.

*GLORP!*

The base of the beast's cock swelled into a plump, juicy knot before his jizz could backflow out of Dash's mouth. It formed an airtight plug as the red rocket shot out a stream of goo. Dash coughed and heaved as, with nowhere else to go, a sticky rope of cum spewed out from her nose. Applejack watched with a horrified expression as Dash gurgled pathetically.

Looking around, Applejack saw the rest of the party fared no better than their ravished rogue. A Diamond Dog held Rarity down on her knees, the shattered fragments of her wand strewn around her. He was fucking her face, ruining her makeup with a sticky mix of tears, spit, and cum. To the opposite side of the room, a pack of Diamond Dogs had literally dogpiled on top of Pinkie Pie, who yelped and gagged as she was buried under a landslide of knotty beast-cocks.

In another corner a hulking beast, more like a feral wolf than a normal Diamond Dog, mounted Fluttershy. It bred the druid doggy-style, its balls slapping rhythmically against her tender clit. Each back-thrust tugged at her pussy with the red veiny knot that was so firmly plugged inside of her. Her belly showed a gravid bulge from the loads the creature had already planted in her, no doubt hoping that the druid would be mother to its pups.

Finally, Twilight bounced on a Diamond Dog's lap, her robe ripped open in the front to expose her tits. The clothes were ruined regardless; the fabric was soaked in so much cum it looked like she had been tossed in a lake of cream. That wasn't what shocked Applejack most, however. Spike had apparently fallen to the influence of a more powerful wizard and was now face-fucking his former master. Roars and hisses echoed off the cavern walls as the pseudodragon ravished his master's mouth. Who could have done this?

A cruel, mocking voice taunted Applejack, "Mmm...Back among the living, I see?" The warrior turned to see a pair of all-too-familiar glowing green eyes leering at her. Chrysalis, the deposed queen of the Changelings, sat atop a carven throne, surrounded by ravenous Diamond Dogs. Her royal clothes were tarnished with dirt and dust from the cave, but now they were inlaid with jewels from the Diamond Dog mines. The villainess cackled, "Leave it to the Elements of Harmony to walk right into my trap. And so eagerly, too! When I had my darling Diamond Dogs kidnap those poor little villagers, I just knew your pathetic leader would take the bait."

Applejack growled, "You rotten varmint! Since when do you work with darned Diamond Dogs?"

"Since you and your meddling friends stole my kingdom from me!" the queen-in-exile shrieked, losing her temper. She stood up from her throne, clenching her fists as she drew to her full height. The Diamond Dogs around her whined, some shying away with their tails between their legs. Two of them-- a short, shaggy mongrel and a lumbering, jowly brute -- rubbed against her like pets trying to cheer up their master. Chrysalis grinned. "As it turns out, Diamond Dogs make much better subjects than Changelings do. It's so much easier to keep on a leash, you know. I don't even need to steal love from them; They give me as much as I want, whenever I want."

"Love?" the Diamond Dogs rubbing against her barked. Hunger sparked in the small one's eyes, and dog drool leaked from the big one's jowls. "Queenie want love?" The rubbing devolved into humping as their cocks pushed out like red sticks of lipstick.

"Oh, I'm positively famished!" she swooned. With a tug, she undid a clasp at her waist and let the bottom of her dress fall to the floor. Revealed, her unclothed pussy glistened with wetness, hungry for love. Chrysalis kept smiling menacingly at Applejack as she scratched the chins of her horny hounds. She cooed, "Care to throw your beloved queen a bone, boys?

The loyal Diamond Dogs leaped to attend to their mistress. The mangy mongrel pounced on her front, eager to stick his cock in her pussy, wrapping his arms around her waist as he plunged his tip inside. Meanwhile, the big one gripped her hips with his hairy paws and railed her ass. Chrysalis groaned in ecstasy as the two puppy peckers thrust into her. She ran her fingers through her hair, her bosom heaving with wanton lust. She shamelessly panted just as heavily as the dogs. All the while, she locked eyes with Applejack, tormenting her with the debauchery of it all.

Unlike the Elements of Harmony, Chrysalis reveled in the savage interspecies union. She howled in perverse exaltation, "That's right, worship your queen! Give me all your love!" Her subjects obediently pounded her, slapping their balls against her taint. Chrysalis widened her stance, giving Applejack a better view as her holes stretched around the invading members. The megalomaniacal monarch leered at the fighter, madness in her eyes. She bore her fanged teeth in a crazed, rictus smile. There was no trace of sanity in that expression, only lust, cruelty, and a will to dominate all living things.

"See how eagerly my subjects wish to please me? These dogs know their place," she sneered. "Even my changelings were never so obedient. Watch." Chrysalis flung her arms wide as her horn pulsed with magic. The Diamond Dogs yipped excitedly, knowing the order that was to come. "Cum for your Queen, dogs," she ordered, "I want your essence! Every last drop of it!" Tendrils of vampiric magic linked the Diamond Dogs' hearts to her glowing horn. They shone with her magic as their essence flowed into her.

It was as if her magic robbed the Diamond Dogs of their ability to hold back any longer. Their thrusts came to a gradual halt, and Applejack saw their knots bulge. Who howls of ecstasy echoed in the cavern as the Diamond Dogs came. Their balls throbbed, gushing semen into the Changeling as she roared out in triumph.

The smaller Diamond Dog dismounted Chrysalis. Her tight lips gripped his knot, but he tugged free, releasing a goopy splatter of jizz from the gaped hole. As he scampered away, Chrysalis pulled herself away from the larger one's cock, unplugging her ass with a wet "pop!" The big mutt woofed and curled up to rest, wagging his tail.

A white trail of cum dripped behind her as she sashayed over to Applejack. "My doggies are such good little soldiers. And such prodigious breeders, too. Why, those mares I had them kidnap will be expecting their first litter any day now! In a few years, I'll have an army of Diamond Dogs at my beck and call. Equestria will be torn apart by my dogs of war!"

Green witch-fire blazed around the perimeter of the room, and now Applejack could see the kidnapped damsels in distress. Each was chained to the wall, their bare breasts swollen, their bellies full. Each was pregnant with pups, a fate the Elements of Harmony would soon share...

Unless Applejack acted now. Feeling her strength return to her muscles, she gritted her teeth -- she'd only get one shot at this. Applejack muttered something under her breath.

Chrysalis stopped her villainous monologue and cocked her head in mock interest. "What's that, my pathetic little pony? Speak up when you're addressing royalty."

"I said..."

Chrysalis leaned forward. Perfect.

"You ain't gettin' away with this."

A Nearly F.A.T.A.L. Encounter

Applejack's arm swung forward in a haymaker, a sharp rock clutched in her fist. Her lightning swiftness was much too fast for the changeling to dodge. It was satisfying to see the smug grin fall off her face as the queen realized her mistake.

*THWACK!*

As the rock struck flesh, Chrysalis shrieked. Applejack thought she had won. But then she realized that, almost so fast she hadn't seen it, a meaty grey paw had caught the rock, stopping it a hair's breadth from the dark queen's flinching face.

A yet-unseen Diamond Dog bodyguard had saved her. At least, Applejack thought it was a Diamond Dog. It must have been some kind of mutant. It towered over every other creature in the room, stooping to fit in the cavern. Its body was a grotesque mass of rippling muscles. Worst of all, upon its shoulders rested not one, but three separate heads.

With another hand, it grabbed Applejack's wrist and, plucking the rock from her fingers, crushed it into gravel. Under the arms it used to disarm Applejack, it had a second set of arms. "What in Tartarus..." Applejack muttered, a quiver of fear shaking her voice as she stared at the canine abomination.

When it dawned on Chrysalis that she hadn't been struck, her fear turned to white-hot rage. "You dumb hick! You nearly hit me -- me, a Queen! I could have your hands chopped off for that!" The mad monarch foamed at the mouth, spittle frothing at her lips as she ranted, "Drawn and quartered! Off with her head!"

The Diamond Dogs barked in outrage, gnashing their teeth at Applejack. "That's too good for her, mistress!" one said. "Yes, yes! Let us punish her!" said another. Their red, veiny cocks wagged at her as any Diamond Dog not fucking another mare begged to fuck Applejack. All but the three-headed giant, who merely growled from all three of his Rottweiler heads, glaring with six merciless eyes.

"No, I want her to really suffer! Cerberus," Chrysalis addressed her abominable three-headed servant. "I think you deserve a treat for being such a good guard dog. Break this bitch."

Applejack screamed as Cerberus twisted her wrist. She had to spin away, otherwise the monster would twist her hand off. Once her back was turned to him, Applejack felt Cerberus's other arms get to work. He grabbed her armored leggings with his clawed mitts. The armor tore apart like wet tissue paper. In seconds, Cerberus and Chrysalis had a splendid view of the fighter's bare, toned bottom.

With one last valiant effort at resistance, Applejack attempted a turning kick, hoping to hit Cerberus in the kidneys. All she got in return was a hard "thud" as her heel smacked into his iron-hard body. The monster was unmoved and responded by grabbing her ankle, forcing her to hop on one foot to avoid falling down. Chrysalis laughed at the humiliating display, and a chorus of Diamond Dogs joined in her mockery of Applejack.

With one hand on her wrist and another on her ankle, Cerberus lifted her and grabbed her other hand and foot with his two empty claws. Despite the weight of her remaining armor, he lifted her like an innocent filly playing with a doll. However, his intentions were anything but innocent. He pulled her hands behind her back and folded her legs against her body, rendering her immobile. Still, Applejack struggled defiantly.

As she writhed, trying in vain to free herself, she looked down and saw Cerberus's shaft erupt from his sheath. The big red dog-dick surged forth, thin blue veins throbbing as it grew bigger than any stallionhood she'd ever clapped eyes on. "You gotta be kiddin' me," Applejack whined as a fat knot popped out from his sheath. Her blood ran cold as more dog-cock revealed itself, and then...

A second knot. Then, a third.

Applejack grimaced at the sight of the throbbing mutant member. It would have been a grotesque display even without the imminent threat of penetration. But as it was, that thing was going inside her, whether she liked it or not (and she certainly did not).

She tried to kick her legs free from Cerberus's grasp as he leveled her slit with his pointed penis, but she was powerless against his monstrous strength. Holding her like a pocket-pussy, he pressed his glistening tip past her entrance, spreading her sensitive lips around his bestial girth. Then, unceremoniously, he slammed her down as far as she could go.

"Ooo-OOOOWW!!" Applejack screamed as the Diamond Dog dick spread her well past the point of discomfort. With one stroke, he brought her down to his first knot, the swollen knob of flesh punching her entrance like a fist. Held tight in his grip, all she could do was whine, "Ow, ow! Take it out!"

Of course, Cerberus didn't give a damn about the fighter's protests. On the contrary, he pushed in even harder, grinding his hips to work the knot into her poor pony-pussy. The hard, hot girth dug into her hole, feeling like it would crack her hips in half. Chrysalis laughed as her prisoner writhed in pain. "Good boy," she cooed at Cerberus, "Give that bitch the knot!"

The mutant monster wagged his tail, growling as he redoubled his efforts. A wretched groan croaked from Applejack's mouth as her entrance spread wider than ever. A moment later, the first apple-sized knot forced its way into her.

Chrysalis licked her lips as the knot created an obscene bulge in Applejack's tummy, her battered body stretching as the second knot met her pussy. The earth pony's sobs were like music to the changeling's ears. It was a fitting punishment for these interloping do-gooders.

The sound of flesh slapping against bruised flesh echoed off the cavern ceilings, lost amongst the murmur of the onlooking Diamond Dogs. They watched restlessly, panting with lolling tongues as they watched Applejack get used and abused. Some of them sported red, throbbing boners, and a few stroked themselves shamelessly.

Chrysalis's attention was diverted from Applejack's punishment when one bold, bulldog-faced Diamond Dog tapped her shoulder. She looked down to see his erect cock, his hips humping insistently at her leg. "Please, Queen Chryssy," it begged, "We want to play too!" He pleaded with his big, wet puppy-dog eyes, his slobbery mouth drooling with desire.

She gave her lapdog a lewd smile. "I suppose a Queen is but a servant to her people," she jeered, her words dripping with false magnanimity. Grabbing his leash, she shoved his muzzle into her folds, forcing him to lap at her wet, sticky cunt. The Diamond Dog ate her out with gusto, his doggie drool mixing with her pussy juice. "As for the rest of you, there's work to be done; I think some of these other bitches have holes that haven't been filled with cock yet!"

At her command, the Diamond Dogs loped to any mare with an open hole. The one face-fucking Rainbow Dash was joined by another. Without a word, the pair began to spitroast the poor pegasus, holding her in the air with nothing but one doggy dick in her mouth and another in her cooch. A pack of horny hounds joined the ongoing gangbang of Pinkie Pie. The party pony had abandoned her sanity, now simply squealing in delight as the Diamond Dogs glazed her with layer upon layer of warm, sticky cummies.

Fluttershy's fertile belly was already full, her cunt firmly knotted by her previous partner. Undeterred, a group of males found her mouth was still available. Two of them took her mouth at once, stuffing the vacant hole with their slippery dicks, pouring precum down her throat before getting to work.

A group of muscular Diamond Dogs surrounded Rarity and held her in place, roughly gripping her mane. They made her look up at them as they bukkaked her from head to toe. Meanwhile, Twilight got triple-penetrated by Spike and a pair of diminutive Diamond Dogs. The rest of the males spread out, panting eagerly as they eyed the mares chained to the wall. They pounced on their helpless prey, more than ready to re-rape their prisoners.

In the center of the orgy, Applejack got impaled again and again on Cerberus's girthy spear. He thrust himself deep into the defeated pony. It was relentless, the way he kept fucking her harder and harder. As the second knot sank into her, she clenched her teeth so much she thought they might shatter in her mouth. After the second knot passed her lower lips, she held a notion that the worst might be over. An instant later, the third and final knot pressed against her abused hole.

At that moment, Applejack realized there was no reprieve, no salvation, no hope for her future. This Diamond Dog was going to stuff all three knots in her, breed her, and keep her in this dungeon forever. She could only groan in despair as the third knot stretched her entrance, passing with a wet "*POP!*"

"Yes!" Chrysalis screamed. Maybe it was from the pleasure of being penetrated, or maybe it was with sadistic glee from watching the last hope flicker away from Applejack's eyes. Maybe it was both; even she couldn't tell. As her harem of Diamond Dogs went at her, she cackled, "Fill that bitch up, Cerberus! I want that miserable mare to get nice and pregnant with your pups!"

Cerberus obeyed, pumping his member into Applejack, her labia gripping his third knot as he pulled it out and shoved it back in, fucking her with it. The veins on his red rocket throbbed, and the three heads on his shoulders panted with exertion, their tongues lolling out. Applejack grimaced as a few ropes of stringy dog-drool dripped over her armored chest.

The thrusts built to a climax. At the peak of his pleasure, Cerberus pulled Applejack against him and loosed a deafening howl from all three heads. The knots ballooned even larger, locking her in place.

"AWOOOOO!!!"

His seed erupted forth, marking Applejack's defeated womb as his property. The stalwart element of honesty let out a dolorous wail as she was claimed. Before long, her tummy would be full of a litter of Diamond Dog pups, loyal only to Queen Chrysalis.

But she didn't have long to meditate on the extent of her failure. Cerberus pulled her up by the shoulders, lifting her up off of his cock. The knots tugged against her from the inside, keeping him from pulling out altogether. At least, not without resistance. Applejack thought the monster might pull her pussy inside out as the engorged knot pulled, stretching her entrance until...

*SCHLORP-SCHLORP-SCHLOPPP!!*

All three knots escaped the grip of her pussy. Applejack felt like she had been hollowed out, she was so stretched by the girth of the monster's cock. His white goo leaked from her gaping pussy, drizzling onto his still-hard boner. His vicious grin told her that even now, the worst was yet to come.

He pointed his tapered tip, lubed with his own cum, at her virgin butthole...and pushed.

Full Party K.O.

"Applejack, roll for anal circumference."

Applejack grabbed her dice before asking Twilight, "What do I roll for that?"

Starlight Glimmer referenced the Ogres & Oubliette extended rulebook. "Let me see...Aha! Roll 1d100+10 and add your anal elasticity modifier."

As Applejack checked her character sheet, Spike interjected from the doorway, "What in Celestia's Name are you girls doing?"

"Relax, Spike. It's just an innocent role-playing game," Starlight explained. Meanwhile, Pinkie and Fluttershy rolled for how many pups would be in their characters' first litter of Diamond Dogs. There wasn't anything "innocent" about Starlight's O&O sessions. Spike was mortified at how the girls' campaigns had spiraled into a weekly session of monster-on-pony gangbangs.

Of course, he wasn't too mortified to stay as Starlight described how Twilight's pseudodragon fluttered over to Rarity's character. Spike caught a salacious look from the real Rarity as Starlight went into graphic detail about the imaginary blowjob.

Maybe he'd stay and watch their game for a few more minutes. Or hours.
