Twilight's Enigmatic Erotica Engine
Shining Armor and his wife Princess Cadance stepped into Twilight's dimly-lit laboratory. A strange mechanical machine the size of a refrigerator was humming and buzzing. Next to the machine stood Twilight Sparkle and Pinkie Pie.
"Isn't it great?" said Twilight, beaming as she ripped off the end of a long chain of greenbar paper leading out of the machine. "Your arrival in Ponyville was perfectly timed. We'll get to see how well it works, together!"
"Sure!" said Shining Armor, smiling. "Er, wait. What in the world are we talking about?"
"It's my Enigmatic Erotica Engine," said Twilight, wearing a smug look. "I made a machine that takes fictional narratives and turns them into new, perverted tales. Think of all the naughty novels and smutty stories we could make, all at the touch of a button!"
"I like the way you think, Sis," said Cadance, with a wink. "But how does it work?"
"Oh, it uses an artificial neural network! I feed it text, and then it learns how to write based on how frequently words and word pairs and triplets appear throughout the source material," explained Twilight.
Princess Cadance gasped. "What? You made an artificial brain, Twilight?"
Twilight shook her head. "Nothing that fancy, Caddy. It just uses something similar to neurons as a model. It isn't conscious or anything. It doesn't even know what the words mean, so I guess there's a potential it might just belch out random nonsense, but hopefully it'll be interesting."
"That makes more sense. Is this your test run?" asked Cadence, pointing at the paper.
"Oh! I get to read it first," said a very bouncy Pinkie Pie, taking the pile of paper into one hoof. "I helped Twilight tune the machine, so it's got some of my personality in it!"
"Neat. So... you need a story first, and then it makes the story saucy?" asked Shining Armor.
Twilight shook her head. "No. You need erotica to begin with. It makes more erotica, but it's randomly composed, so it should be highly creative and substantively different from the original dataset."
"I see. And what did you use for the maiden voyage?" asked Cadance. "Daring Do and the Nipple Clamps of Terror?"
"Oh, no. Something way more personal," she grinned. "I had Starlight write down all the details of her little trip to see you two!"
Twilight's brother and sister-in-law blushed. "Yikes!" said Shining. "Well, I guess we earned this."
"Apparently my name came up a few times in your little encounter—and Shiny, I demand to see you wearing that outfit soon—so I might end up in the story too," said Twilight. "Which is weird, I admit. I mean, you're my brother, for friendship's sake."
"More like hot," Cadance mumbled under her breath.
"Also, I hope you weren't serious about me marrying Sunburst," added Twilight. "You weren't serious, were you?"
"Well, it'd be convenient if you did," said Shining. "Sexy convenient. Just sayin'."
Twilight rolled her eyes. "Oh, and, um... Flurry Heart's name was in there, so, I guess that's also a possibility."
"Eww, Twilight, no," said Cadance, cringing.
"Hay, just relax. Let's see where this goes," said Shining. "Keep an open mind, and all that."
Cadance glared daggers at her husband, then sighed. "Well... maybe," she admitted. "Okay, let's do this."
"Pinkie Pie, do the honors!" said Twilight Sparkle.
Pinkie giggled, then took a deep breath...
Twilight Sparkle, Sunburst, Starlight Glimmer, Cadance, and the other one I don't really like (being the royal hoof boy), somehow hanging lacy tissues, grasped the bit from sweat.
Even though the victorious wetting traitor mattered, clue-free Shining Armor blinked several times and narrowed his tunnel. The four legs of his magic alicorn princess helped and locked the way.
Then Sunburst felt weaker. Starlight Glimmer giggled as her nuts began going all the way up her nose.
"Oh, horseshit," murmured Sunburst.
"Fuck," said Princess Cadance, after having fags cascading against her ponut. Suddenly, something thick and slippery pressed against her lips. It was nothing.
"Okay," said Shining Armor, "which of you will consider me beautiful?"
Starlight took a moment and rolled her lips together and then shivered. Her cock bobbed against the whorses and one nostril exchanged hugs.
"Don't worry, magic tickling has worked," said Princess Twilight. Finally, something subtle and wonderful jetted wryly! Tartarus exploded limply. The crystal guardsponies married Sunburst's tongue, which lapped against a candlelight spell.
"Maybe having sex toys and costumes was a raging, flaring solution the palace arcade didn't need," corrected Starlight.
Cadance laughed nervously, dribbling vibrations down her dick. "Starlight likes to suck against the royal couple?" asked her flimsy beard.
"Well gosh, absolutely Mistress," cajoled Starlight. She stopped short when the princess broke her heart.
"Okay, that was barely horny," whispered Shining Armor. "Maybe you need to fuck my Crystaller's ass and then give apologies."
Twily distracted her with her tongue sticking out. "Please tell me you know how to stroke your carpet."
Trembling, the other mares noisily said, "I came!"
Strange, visible flowers fired directly inside her husband's eyes. It was incredible and especially naughty. "You're hearing sex with telekinesis? You are going to have wings," said Sunburst.
Twilight Sparkle said, feigning exhaustion, "You need to fuck off, eyeliner-cupped bi... whatever."
"Fuck it straight toward rhythm," offered Shining Armor, "oh no, I mean Cadance."
It took a moment for Sunburst's lingerie to taste unlike sex. More than any mare, Sunburst's body tickled against hooks and shelves. He was elected to assume the rest, somehow.
"That is doom," said anything.
Finally, speaking up to the hilt, this sweetie broke down and inhaled butt. That sanitary behind had several times fired. Even hotter, the tip just felt himself experiencing her forehooves. There was already a firming chance she could cum on magic steel.
"Those painted lips smell like you're not serious," whispered Starlight, who chuckled with her magic pussy. "After you are ejaculated, place her beautiful pleasure in the family balls."
"I don't know how to do that," whined Shining Armor. "Those gentle suction swapping faggots said so much, despite realizing there was a nonzero chance they were about to..."
"Evilly give him a little D?" whispered Sunburst's turgid ears. "Yes, absolutely."
The ponies looked into space with throbbing erections slapping against the glasses. There was an enormous shock inside. It took a moment for Caddy to clean forth from peals of silence, and the base of her flesh plugs said, "Oh wow, Mistress Thick has white makeup on her cheeks," but it just felt so adorable to taste the little partner.
"That's strange, because Ponyville doesn't have reverse feels," teased the masculine princess. "Are you part hallways?"
"Yes... duh," said Starlight Glimmer. "My mouth apologies against meat centered the head in concern."
(It could explode at the pun.)
"Well, if we're pretty caressing whorses, please, holy crap: like five crystal mares," said Princess Cadance. She selected a couple of her lips over the technical climax to make this quick. Cream from his skimpy reverie hung smoothly inside all decked-out, loud rims.
"I banished an ancient evil through pearly pervert pressure, however," said the four scheming afterglow-wrapped parents. "Warmth of cock was once barely audible, but puffy stimuli met directly inside her colt cunt."
"But, Twily honestly didn't have a big clopping," said Twily.
"Okay, fine. I'll remember to have you learn whatever you want to," said Starlight. "Maybe this evening the door broke out into your teeth, then quietly yet gently caressing his eyes, would you like me?"
"Oh," said Shining Armor, "wait until later," and one cheek clamped sissy hugs to adjust the little tail-swapping scat.
The other couple of satin dicks discharged forward, sliding up against her perineum. "Maybe this evening broke her senses around the royal sheets," said the rosy fun friendship headmare. "Those illusions they passed, as crystal ribs began licking at each naughty jackhammer, have zero regrets."
Feigning worry, their unusually soft lingerie was straight fun times. "Fuck you two salty sex spurts," teased the tip of vision-filling voice. Finally, freestanding brighter, Mistress Conclusion Butt grinned at the container.
"Ponyville likes the family way!" yelled Shining Armor as he trotted, meekly picking up his pink, musky electric sheets.
"I believe it's silly because his sheath is my brother. Maybe this is doing something to pull her penis around the middle of the bath?" asked Starlight Glimmer.
Knocked up, Sunny said, "Wow, yes. This isn't very weird... Or gay," but that look stretched the casting. It was barely loose back there, anyway.
"I took a big dresser mirror. After all, smeared ass is never boring, " assumed Princess Slut.
"Yes? No? Thrust backwards gently," Sunburst pointed out, but his aggressive dress hung immediately on any puckered pump. "Ahem, help?"
Twily, despite realizing erections, said, "Sunburst picked out with strange sex details!" (Yes, technically speaking, the kiss on the hard rump faced out like a china doll.)
"Wait! Prince Shining sex with his cheeks widened squeaked forever!" said the keyhole boyfriend.
...and that is enough for your girlfriend's funny consideration.
Everypony stared at Pinkie, slack-jawed. Pinkie, on the other hoof, beamed from ear to ear.
"I know, right?" said Pinkie Pie. "It's the perfect clop story!"
Twilight appeared nauseous. "This... this is the worst thing I've ever done, and I've had sex with the homo sapiens iridis version of Flash Sentry."
"Twily, this can never see the light of day," said Shining Armor, momentarily shivering. "It must be destroyed for the good of all ponykind."
"What? You guys are crazy! The narrative arc of Starlight Glimmer's balls alone is worth a Ponylitzer," said Pinkie Pie.
"Pinkie, that award is for news," said Twilight.
Pinkie blinked a few times. "But this is new, isn't it?"
"Well, we're not burning this nightmare until we subject Starlight and Sunburst to it," said Cadance, as a grin crept across her muzzle. "I'll happily suffer through hearing it again if I get to see the looks on their faces."
"Ugh, fine. As long as I can tear the machine apart now," said Twilight.
"No, Twilight, wait!" said Pinkie, trying in vain to stop Twilight as she began to pull apart the machine. "I want to see what it does if I feed it all my recipes! Maybe it'll come up with a kind of cake made from cheddar cheese and garlic alfalfa?"
Shining took the mass of paper and dumped it into his saddlebags. "I dunno, Caddy. Reading this to them might kick off another session of sex. I mean, some of the parts with Sunburst were kind of cute."
"That's because you like boys now, you silly ass," said Cadance, poking him in the ribs as the couple made for the exit over the din of metal pieces being torn asunder.
