A semi-dark clop fic, starring Twilight Sparkle, lyra Heartstrings and Anonymous...

The land of Equestria....... A place of love and tolerance... Seems like a swell place. But for Anon, being the only one of his kind in a world of equines with human levels of sentience and curiosity, will see him as a subject to twisted experiments conducted by one particular lavender coloured pony in a attempt to ... understand him...

ALL HANDS ON DECK CAPTAIN!!! SOME F*#!ED UP SHIT AHEAD!!!

CHAPTER 1 - Wakey Wakey...-

Anon's eyes flicker as he begins to come to. "Ugh ....... What?-" Anon grumbled rocking his head side to side. But before he could analyze the situation, A piercing ache in the back of his neck halted his thoughts. "Oooooooo. Ok, yeah, that really hurts." Strange, while Anon usually forgets practically everything after a hard earned shitfacing the night before, he would at least remember that he even did it in the first place. Attempting to feel the back of his head, Anon noticed a surprising lack of mobility in his left arm ... and right ....... come to think of it .... all of his appendages.

"The fuc-" Anon looked around, eyes and mind finally adjusting to his surroundings and realizing the severity of his predicament. Both his arms and legs were sprawled outwards, wrists and ankles fastened by chain cuffs to the corners of a sleek platinum table he currently was laying on. Continuing to look around the rest of the room, the human noticed he was surrounded by complete darkness, the only source of illumination coming from the ceiling light dangling just above him, as well as a grey, seemingly unkept window filtering the light it bled into the room into a faint murky blue hue. Judging from that, Anon could assume it was still night out, which only made his situation more intimidating.

----

Anon began to struggle with his bindings, hopelessly pulling and yanking, but to no avail. He knew there was no way he could physically break free from his unexplained imprisonment with just sheer strength alone but he still continued to out of what seemed to be basic instinct.

"Hmmm... even though his escape is futile, he still attempts to break free, even given the implausible scenario that is well beyond his physical capabilities."

Anon looked up as he tried to locate the disembodied voice that seemed to come at him from all around.

"W-who's there?" He shuddered, trying his best to mask the fear in his voice. A giggle crept its way through the shadows.

"Hehehe." "Though he seems to have attained his sense of awareness quite quickly. Glad to see I wasn't to rough on capturing my precious sample." The voice seemed somewhat familiar. It was a soft feminine tone that Anon felt he already knew. The figure to which the voice belonged to, stepped into view at the foot of the table.

"P-Princess Twilight Sparkle!?" Anon choked. The lavender alicorn gazed down at the human, her magenta eyes locking onto his sea blue ones.

"hmhm.. Please, there is no need for these traditional formalities, you may address me as "Twilight" my dearest Anon." Twilight said placing a hoof to her chest.


"uh- uhh, ok, Twilight.. May I ask why i'm stuck here? ... I-I swear I didn't do anything wrong ..... I think..." Anon mumbled the last bit under his breath. He knew he was capable of doing some pretty stupid things whilst completely ignorant to it.

"Oh of course not" Twilight shook her head giggling. "On the contrary, you're going to help me, and Equestria in the name of SCIENCE!" Her eyes narrowed as a maniacal grin that stretched across her face. Anon reeled his head back slightly.

"How... so?" He was fearful of what her response was going to be. Twilight clapped her hooves together.

" Oh.. so glad you asked! " she said franticly excited. "You see, you are a rare breed here Anon, like, reeeeally rare. I'v seen and befriended, creatures of your kind before in another word, but i never really got to study them for myself ... ..Physically .... And up close ... Unfortunately your species doesn't exist in our plain of existence. so when you appeared here whilst maintaining your other worldly form a few months back, I knew i had the perfect opportunity to get my hooves on you, a human, as my personal test subject." Anon laid motionless on the table blinking at Twilight, taking in what he had heard.

"And just what do you plan on doing to me that would require you chaining me up?"

"I plan to explore your body in a way I won't think you will be complying to."

"W-what does that mean?"

"Why ask questions you already know the answers to?"

Anon was sweating now. "No .... No, no ,no, no, ABSOLUTELY no" he began to wrestle with his chains again. Anon remembered hearing rumours in town about Twilights escapades in the human world concerning her fetish for human men. It seemed to be brought up in private conversation between ponies, which you happened to catch wind of, when they noticed you on the streets. She had apparently acquired the taste during a mission to retrieve her stolen princess crown from the previously exiled Sunset Shimmer in the human world. Since Twilight left during her second visit, she grew to put her thoughts on the subject behind, but her curiosity for "Ahem" "Human head" was rekindled when he appeared in ponyville a little while back. Twilight licked her lips as she felt up Anon's left leg.


"Wow, I-I finally get to feel your bare legs" Twilight sighed. "I-I'v always... wondered..." she continued rubbing up and down his leg, feeling its structure, marvelling at its alien design. "Mmmm" Twilight moaned as she brought her muzzle to the human's leg, and began to lick around his calfs. Anon jolted at the touch as she began to slither her tongue along the muscle up to the side of his thighs near the ends of his short's.

----

Anon gritted his teeth. "Sorry Twi', I'm flattered, really, but i've only been here for three months. So i'm not deprived of enough sanity to start getting my rocks off to horses." Somehow that sounded funnier in his head. Twilight slowly looked over to her captive with a large grin on her face. She hopped onto the table, and crawled along his chest until her head met with his. she looked into him with half-lidded eyes and before anything else, brought her hoof across his face, drawing a yelp of pain from the startled human. A trickle of blood ran down his nose, and a bit more from his now cracked lip. Anon's eyes clenched shut in pain as he grunted under his breath. He looked back up at the alicorn, wide eyed and surprised.


"Now now." Twilight cooed. "Me thinks you have forgotten your current position." Anon's lips quivered with pain and a touch of fear. Twilight leaned in beside his ear and whispered, " I think you are smart enough not to deny your princess of what she desires." Her voice still soft, but any rationality, Anon felt hope for from the lavender pony earlier, was gone. Twilight raised her head back up and brought her hoof gently to the young man's chin. Anon began to twitch slightly. "And first off, Twilight began, I said you could call me "Twilight" not " Twi' " . she calmly spoke." And secondly, we are ponies, not horses silly." Twilight's horn glowed a purple aura as a tissue appeared before them. wiping away the stains on Anon's face, Twilight crumpled the tissue and threw it out into the dark corner of the room.

----

"Sorry my dearest Anon, it truly hurts me more than it hurts you to do such a thing to such a cute face. However, A princess has to do what princess has to do to ensure that she remains in charge and dominant." Twilight licked her lips. "Now then.... lets get started in our experiment."

Chapter 2 - Sharing is caring

Twilight brought her nethers alongside Anon's face, leaning over his head, and propping the rest of her body on her front hooves so her belly rests on his forehead.

"Let's start with seeing how those tongue muscles of yours work." Twilight chuckled.

She began rubbing her folds along Anon's bruised nose and stinging lips. He clenched his fists, the slight sting washed over his face as her vaginal fluids leaked onto his cuts, and her pelvic bone pushing on his presumably broken nose.

"Mmh.. Mmmh!..." Anon's grunts were muffled by the purple mass on top of him. The sound of chains rattling when he shook his arms as Twilight pushed herself harder into his face.

"Come now hun, work yourself in there." Twilight sighed, bitting her bottom lip, as she tightened her thighs around her captive's head turning his muffled grunts into vibrations. Anon knew the pressure would continue to get worse if he didn't start getting to business. Swallowing his pride, he brought his tongue past his quivering lips, and stuck it in between the lavender folds in front of him. "Mmmmmmm yessss." Twilight cooed, her mane falling from behind her ear and draping over her face. She began to pant heavily as Anon started to pick up the pace with his tongue. A warm fleshly sensation flooded over his mouth and nose as both had entered inside his captors sex. The stinging he had felt earlier had now simply gone numb while he could hear Twilight's groans and gasps get louder as he pushed further into her.

"Yeah, yeah ..Mmh.. Yes!" Twilights grinding began to pick up with more momentum. "That's pretty good, but I strive for grade "A" effort." She whispered. A purple aura swirled up a cluster of Anon's hair at the top of his head pulling him more aggressively against Twilight's drooling mare-hood. She could here the poor human gagging and sputtering on her juices accumulating over his face.

"Oh, so your a spitter?" Twilight scoffed, continuing to rock back and forth. "Well, I would prefer you swallowed most of it, your making quite a mess down there."

"Mmm, mm!" Anon mumbled in a disapproving manner.

"Hmm? Im sorry I didn't quite catch that. You shouldn't talk with your mouth full, it's rather uncouth, especially before a figure of royalty."

Twilight brought her waist up from Anon's face as he coughed and hacked up the mare's fluids, his face soaked with a mix of vaginal juices and his own blood, smeared all over his lips and cheeks from Twilight riding him. He crooked his head upwards to look up a the twisted pony, breathing heavily, with a scowl over his stained face.

"So sorry" The alicorn said with a smug expression on her lips. "I probably should have let you breathe a bit. I can sometimes get a little careless when i'm excited." Anon's expression remained as it was, his gaze still fixed on Twilight. "It also seems I have caused you to bleed a bit more as well, again, my sincerest apologies. Twilight passionately rubbed his cheek, smearing around the filth on his face.

"That was just a warm up sweetie, So don't get to relaxed. We'll clean you up a bit and then get down to the more important matters at hoof, or I guess in your case hand." Twilight chuckled. "Oh, and speaking of "hands", I'll be having an assistant come by to join in, so you're gonna have two of us to worry about, I hope you won't mind." Twilight called over, walking off into the darkness surrounding them.

"An a-assistant?!" Anon wheezed, still catching his breath. "So what was that about me being your PERSONAL subject?" He coughed.

"Well, being something thats personal to me, means I can do whatever I want with you" Twilight spat back, as she returned with what appeared to be a bucket of water floating beside her.

Instead of lightly scrubbing Anon down, Twilight levitated the bucket above his head, dumping the cold water down onto him, thoroughly cleaning all the filth off his battered mug.

"Gahh!" Anon yelped at the cold wash.

Twilight rolled her eyes as she threw a towel over his face and began rubbing him down. "Oh come now, don't be such a filly, all your whining isn't doing you any good besides making yourself look agonizingly pathetic."

"I don't give a flying fuck-Buck... Anon corrected himself while he threw up a middle finger from where his hand was shackled. "Wait, how does it work here again?"

Twilight held his hand with both hooves giving it a lustful stare. She pushed on each finger observing it's articulation, moving them about, figuring out how they function. "Mmmm, I heard some rumours, about what you could do with these from somepony." Twilight eyed each finger. "I bet she would give just about anything to see these up close, Better yet touch them."

Anon laid quietly, watching the princess intensely while she explored his appendages. "Coincidently, she'll be the one joining us tonight. Fore warning, she is quite obsessive over your kind, specifically these unique body parts you call "hands". So don't feel to intimidated if she gets to excited." Twilight was then interrupted by two short knocks echoing throughout the building.

"Ah, speak of the devil, that must be her."

Twilight walked back into the darkness, out of Anon's sight, with only the sound of her hooves clopping on the floor. He heard a faint click of a handle, followed by the creek of a door opening. No greetings exchanged between Twilight and this unidentified guest of hers, just the sound of the door closing, and two sets of hooves now returning to the spot were the human waits. One set of hooves stopped abruptly, then so did the next in response.

"I-Is that him?" A slightly scruffy feminine voice squeaked.

"The one and only" Twilight replied.

Anon looked back upwards to see who this new pony was behind him. Even though his gaze was upside down, he made out what appeared to be female unicorn with a mint coat and matching mane with white highlights, as well as large wide ember eyes staring back down at him.

"He... Looks... beautiful!" the green pony gasped, holding her hoof to her gaping mouth.

"((Well that was the first time anyone said that to me))". Anon thought to himself.

The new unicorn trotted over beside the table to get a closer look at the bipedal creature, her eyes widening in excitement.

"Anon, allow me to introduce you to a good friend of mine, this is Lyra Heartstrings, Lyra, Anon. But you already knew that." Twilight smirked with sultrily in her voice.

Anon looked up in confusion. "Wait what? this is the first time i'v met the girl."

Weeeeeell, yes, this is the first time you've met me. However i'v had my eye on you for some time." The mint coloured mare confessed.

"I'v been watching you ever since you first arrived in ponyville. Twilight caught me watching you from across Sugercube corner and instead of busting me, she struck up a deal between us.

He knew it. He always felt like he was being watched during his visits in town, and this, Lyra pony just proved it. "Oh really? Watching? I think you mean "Spying!" Anon sputtered, anger building in his voice.

"Same diff'." Lyra snickered.

Twilight slid in on the other side of the table."Lyra's fascination for you rivals even mine. So when i found out another pony had an interest in humans, I used the opportunity to get her close enough to your table without being noticed and cast a little sleeping spell in on tea while you were using the little colt's room. Unfortunately due of my newly acquired status as a princess I wouldn't have gotten close without catching the whole towns attention."

Hearing the ponies plan explained only irritated the human more."What the hell?! I'm living mammal, like you, not some... Thing! For you and your friends to play with in a science class room for your amusement!"

Twilight and Lyra just stared down at Anon, ignoring his hissy fit. Both ponies looked up at each other, then back down to their prize each with lust in their eyes.

"Shall we?" Twilight whispered seductively as Lyra smiled.

"After you" she chuckled.

Chapter 3 - Double Trouble

View Online

The two ponies wasted no time going to work, hopping on top of the table, claiming the prize for all their hard work.

"You can take face first, I already got started there." Twilight snickered while slipping on anon's waist.

"What? You should've waited for me, come on, we're supposed to be a team here." Lyra sarcastically shot back, while positioning herself so.

Anon looked up to see Lyra's already leaking mare-hood directly over top of him winking, as he felt droplets of her stimulation falling on his face. She hadn't even started yet and she was already practically pissing all over him.

Lyra looked down at his face and smiled.

"You won't believe how long i'v been waiting for this." she sighed, rubbing the end of her hoof against her clit, as it continued to wink, begging for more attention.

"Its only been three months since you arrived here, but its felt like years!"

Anon's eye's twitched slightly with fear, as the mint coloured unicorn gazed down at him with a sadist and lustrous look on her face. What ever she was going do, she wasn't going to be anymore gentle then Twilight was with him. If he remembered Twilights warning she was a psycho when it came to anthropology.

Meanwhile at Anon's south, Twilight was inspecting his member, fascinated by its shape and texture. She bobbed it back and forth between her hooves and would give it a light stroke down the shaft, eyeing it with both lust and curiosity.

"Hmmm, a few similarities to a stallion's but still unique on it's own. instead of flat, the head is round, no sheath, just hangs out..." Twilight started getting a little carried away, as she always does, inspecting every detail, taking notes in her mind. She gave the shaft a sniff and slight lick, pondering the taste.

"salty and sweet...interesting." she thought out loud.

Lyra looked back pouting. "Stop teasing Twilight, I don't want the surprise to be spoiled for me."

"Oops, your right, sorry Ly' " Twilight giggled. "You know how I get. Forgive me."

Twilight perched herself above Anon's cock, letting her slit kiss the top of it. Slowly but steadily, she brought herself lower, anticipating but cautiously bringing in the alien form. It scrunched up slightly as the alicorn forced herself harder onto Anon's member.

Twilight's horn glowed that familiar hue, signalling something to happen. suddenly a sharp pain filled Anon's head causing his eyes to widen, as a pain filled groan gurgled from his mouth. He began to convulse slightly as he could feel a warm sensation moving down his body to his stiffing shaft. Twilight was controlling his mind telling his nerves to send chemical messages to his penis to stimulate.

"Fascinating, your brain mechanics are shockingly similar to ours in terms of driving sexual desire." Twilight said while keeping her focus on his body.

"Sorry, this will hurt a bit."

"What are you doing Twilight?" Lyra turned over in curiosity.

"Manually stimulating him using a spell to control the nerves in his brain." Twilight responded, her focus remaining on her human test subject.

Lyra scrunched her muzzle. "Ugh, kinda creepy, and it sounds painful."

"Science isn't all sunshine and dandelions, unfortunately you gotta do some questionable things, but thats just progress."
Anon's penis was now fully erect, and had expanded inside Twilight.

"Ahhhh there, we, go." She gasped, bringing herself down the rest of the way on the Anon's cock.

Twilight began pumping up and down on his shaft vigorously, picking up speed as her love cavern loosened up to let in more and more of his penis.

Twilight Gasped, panting harder and harder, throwing her head back while arching her spine as each pump drove her further to orgasm. Anon, on the other hand, clenched his teeth, the pressure in his member swelled inside uncomfortably.

"Urgh, uh, s-stop, Twilight that hurts!" Anon hissed through his teeth.

"Hey Lyra, do me a favour and shut him up, otherwise we'll be hearing this all night."

"Way ahead of ya' purple butt."

Anon's attention was drawn back to Lyra still standing above his head. She dropped to her knees as her sex squished against his face. She wiggled her hips in circles causing gushing noises. He couldn't keep his eyes open as the green blur rubbed aggressively around his mouth, splashing Lyra's love juices about his face distorting his vision and causing him to choke and sputter.

"Ahhhh yesss thats the stuff!" Lyra's tongue laid lazily out the side of her mouth, saliva running down her jaw, eyes rolled upwards. "I reeeeeally needed this!'

The stinging began returning to anon's lips and nose, along with the burning throughout his body as Twilight had commandeered his nervous system. His whole body felt bothered and hot as the two ponies carelessly went to town on top of him.

*Translated muffles* "P-please, yo-you guys, I- c-can't, i can't brea-, my body's on fire, sto - ughhhh!" Anon began wheezing.

His arms and legs rocked freely around the table as if he had given up on resisting, letting his limbs go limp. Lyra looked down at Anon, taking notice to his silence, and rose slightly to get a better look at the humans face. His eyes were glazed over, half closed, with his mouth partially ajar.

"Oh my I think I over did it to quickly, The poor boys been knocked clean unconscious."

Twilights aura on her horn intensified in brightness as Anon's body jolted and twitched.

"Hey! Wake up! no sleeping on the job!" Twilight scowled as she kept pumping on his shaft.


"Gah!! Oh! Ugh!" Anon came to, head jerked upwards as he gasped and coughed regaining consciousness.

"You better keep your head in the game and tend to Lyra's mare-hood properly, understand!? Right now your only purpose for living is to serve our cunts! " Twilight roared in ecstasy as she kept pounding herself on the human's member.

Lyra stared down with a smirk on her face. She grabbed each side of Anon's head facing him towards her, his eyes flickering open, still breathing heavily.

"You herd the princess. Better do what she says or she might mess ya up even more." Lyra giggled. Anon rolled his eyes to meet hers.

"Y-You guys, a-are sick." He coughed.

Lyra just smiled and rammed his face back into her snatch, forcing her plump lips into his mouth. Anon's cursing was brought to mumbles once again as the mint coloured unicorn pushed herself back and forth against his face. Meanwhile, Twilight kept busy in his down-under, thrusting with all the effort her royal booty could muster. Lyra spun around whilst keeping Anon's face locked between her thighs while facing The purple princess. Grabbing Twilights shoulders, Lyra brought her face to her own, invading Twilight's maw with her tongue. Twilight began pumping even harder.

"Ah - Ahhh! Oh sweet Celestia! I - I'm getting close!!" Twilight groaned, legs shaking, as she was now reaching climax.

The two ponies smacked on each other while riding the human on both ends. Forcefully kissing each other in violent lust while moaning and groaning to the attention down below.

"OH OH!!! OH BUCK YES!! I'M COMING!!!" Twilight groaned loudly not breaking contact with Lyra's mouth. Twilights body tensed up while her legs started shacking harder as a clear liquid sprayed form her swollen sex.

After a few minutes of enjoying their make out session, they broke their kiss almost simultaneously. Lyra looked into Twilight's eyes half-lidded.

"Switch?" Lyra asked.

" *sigh* oh alright. I can see you really want to have your turn. " Twilight closed her eyes shaking her head.

"Eeeeee!" Lyra squealed in joy.

The two ponies dismounted Anon, giving him a breather. Gasping for air, Anon lay motionless in all the mare's filth, shacking slightly, trying to speak while breathing in at the same time.

" *Gasp!*Enoug- *hack* STOP!" Anon screamed.

Twilight looked over at him with an emotionless grin. She just stared into him with empty, soulless pupils, clearly she gave no lick of concern for the poor guy, and once again, lit up her horn. Anon's eye's widened as his chest shot up in the air and began to scream in agony.

"GAHHHHHHHHHHHHHHHHHH!!!!" Anon shook violently in his restraints. "STOOOOOP!!!! PLEEEEEASE!!!"

Lyra looked in awe and shock as Twilight inflicted some sort torturous spell which seemed to be agonizingly painful.

"Wow, remind me never to get on your bad side." Lyra scoffed. Twilight ignored Lyra and continued to look forward at the poor human.

"Sorry Anon, please bear with this a little longer. You'll soon come to find peace with us. Just give it time."

Anon fell back to the table panting and wheezing even harder then he had ever before. Slowly bringing his hand to his chest, he clenched his shirt, saliva running down his mouth, eyes wide as saucers. Twilight smiled softly, her sultrily smile growing even wider along her face.

"Mmmm you look really hot when your suffering." Twilight rubbed her hooves along Anon's chest. Anon glared over at Twilight, not in anger, but in fear. Tears began to well up in his eyes.

"Please, please I beg of you don't do that ever again." Anon's voice cracked as if he was going to cry at any moment.

Twilight smiled down at him.

"Well.... you did get me to climax.." Twilight pondered off. "So I guess I could oblige. Even though you did look cute in mortal peril." There was a sincere tone in her voice that assured Anon that she was going to respect her promise.

"All right, all right. enough talk, Its my turn to ride him now! Twilight keep that Erection-spell thingy on him! I'm going in! " Lyra wasted no time climbing on top on Anon's waist, gripping his cock in her hoof, positioning it beneath her lips causing Anon to yelp in surprise. Without any warning Lyra slammed down on him as she let out a animalistic grunt.

"Your all mine, Human!"
