Background: I wrote this as a follow-on to a green written by someone else in the /mlp/ Flutterrape thread (Flutterrape 5/3/2021). The premise was that Empress Fluttershy, the gossamer gown wearing, rapey sovereign of another dimension, was traveling to different dimensions looking for an Anon that met her specifications for genitalia size and not being generally pathetic. Before my follow-on begins, she had just forcibly measured one such Anon as 5.2 inches when erect; her specification is at least 10.0 inches when erect. We join her as she is on her way to the next dimension in her search. She is about to meet a very powerful Anon that has never seen a Fluttershy before. Before this follow-on, Empress Fluttershy has presumably never had a problem forcing an Anon to have sex with her. Hence, she has never before had to resort to fetish tricks either.

The follow-on is purposefully outrageous and over-the-top. I used JoJo's Bizarre Adventure, Dune, Fight Club, Dragon Ball Z, The Princess Bride, and my own martial arts experience as inspiration and/or inputs. Also, there's some fun with geometry.

>Empress Fluttershy muttered angrily to herself as she traversed the void to the next inter-dimensional portal.
>"Infernal royal mathematicians! They told me there was a non-zero probability of the existence of a 10.0 cock Anon in the space of infinite dimensions. I'm tired of searching! If I do not find him soon I shall have those mathematicians gelded!...NO! I shall have them beaten on their testicles, and THEN gelded!" she said with a furious stamp of her hoof, tinkling her gold bangles.
>With a frustrated look, she stepped through the next inter-dimensional portal.
>"BIZOOooOOooOOooOOMMMMMMMMmmmm" went the unzipping portal as Empress Fluttershy stepped into a large room with dark oak floors, ceilings, and pillars. The walls were thick whitewashed panels with oak beams interspersed between. There was no furniture.
KA-CHUNK!, KA-CHUNK!, KA-CHUNK!
>There in the center of the room was a rather large Anon artfully taking chunks of wood out of a practice wood pillar with a great blackened steel falchion. He had gigantic spiky yellow hair and wore a red robe with a black sash and undershirt, as well as black leggings and forearm gaiters into which the robe was neatly tucked.
>"Well, THIS should be interesting." Fluttershy muttered in annoyance.
>"You there, brute! Stop playing with your silly toy sword and get over her so I can measure your pee pee and oblongs!" she said as she started to walk over to the Anon.
>No sooner had she materialized her record book, fluffy quill pen, and tape measure with matching white rabbit keychain, then a rotating seven inch knife whizzed past her head, sending a sharp breeze through her hair. It took her book with it, impaling it against one of the oak wall beams.
>"Unpardonable impudence!" she said furiously after a gasp. "You dare resist my authority? You'll pay a heavy price Anon!"
"Who are you yellow horse? What are you doing in my house?"
>"I ask the questions here, Anon!" she said as she stamped a hoof, sending her gold bangles jangling again. "I am Empress Fluttershy, ruler of the Equestrian Combined Empire. But I order you to refer to me as either Empress, or Fluttershy. Saying Empress Fluttershy simply takes too long and it irritates me!"
>Fluttershy then activated her horn, confident she could strip him of his clothes and end this with brute force. She grimaced triumphantly as her aura enveloped Anon.
"Muda! Muda! Muda! Muda! Muda!" Anon yelled as Fluttershy's aura flickered and dispelled.
>"Impossible! You have magic?"
"No, silly horse! My infinite belly of chi allows me to accomplish many things some would consider unnatural. NOW LEAVE MY HOUSE! Go out from here and take your own useless dimension for all you can get."
>Setting her face like a flint with a twisted smile, Fluttershy materialized a broadsword and held it in her aura.
>"House? Pffffft! It is trash dump by my standards. Very well, Anon. We shall do this the hard way!" she began walking toward Anon, picking up speed and steeling her eyes as she went. She was menacingly swinging her sword in figure-eights and gritting her teeth in a snarl.
"Oh? You're approaching me?" Anon did some fancy blade spinning with his falchion and likewise began moving toward Fluttershy.
>In a moment they had engaged in a ferocious exchange of slashes, blocks, thrusts, parrys, and spins. Their footwork and...er, hoofwork...was brilliant as they moved over the floor. White hot sparks were sent sizzling through the air with each stroke.
>Now Fluttershy began to gain the upper hand, driving Anon back. She showed her pleasure with a perverse sneer.
>"Take that!" she said as she managed to crash her hoof into his groin.
"Ungh!" Anon staggered back, but used his powerful chi to suppress the pain. He spun his sword and landed in a fighting stance again, ready to continue.
>Wide-eyed, Fluttershy nodded in genuine admiration.
>"You have oblongs of steel, Anon." Then with a wicked growl she continued her attack. "You're gonna need 'em!" She relentlessly continued to put him on defense and drive him back. 
>"Not so brash now, eh Anon? YIELD ALREADY! Submit to measurement!" she said with another slash.
"NEVER! Though, I admit you may be better than me." he said smiling, as he countered with an evasion.
>"THEN WHY ARE YOU SMILING YOU WRETCH?" she screeched in boiling fury.
"Because I know something you do not know." he said with a counter thrust.
>"Oh? And what, pray tell, is that?" she said, mocking.
"I am not right-handed." With that, Anon shifted the great falchion into his left hand and came at Fluttershy with incredible vigor. "WWWRRRYYYYYY!!!" went his battle cry.
>Real concern took Fluttershy's face as she was severely beaten back. Using an adept evasion to create space, she took a warrior's breath and reset her stance. Her eyes spoke murder.
>"Oh yeah! Well, I know something you do not know TOO!"
"Oh? And what is that?"
>"I don't have ANY right hands!"
>Making a feint to the right, Fluttershy combined a distracting slash from the left with a burst of magic aimed at his falchion.
"WHOOOSH-OOSH-OOSH-OOSH-OOSH-THUNK!" the falchion sang through the air before embedding itself halfway into an oak pillar. "OOOHHHH!" breathed Anon at the unexpected turn of events.
>Fluttershy paused to gloat.
>"See that, you filthy beast?!" she pointed to the embedded falchion with her sword. "That's what your pee pee is gonna do to my pussy by the time I'm through with you! You should fear me!" she said this as she smoothed out her now tattered gossamer gown and removed her golden yoke for more comfort.
"I WILL NOT FEAR! Fear is the mind killer. It is the little death that brings total oblivion! Instead, I will allow it to pass over and through me! When it is gone only I, ANON, will remain!"
>"Huh?" Fluttershy responded quizzically. "Whatever. Here I come again! Tell me when you're ready to give up!"
"I shall not yield, yellow horse!" But now it was Anon who was frantically evading Fluttershy's attacks, missing many by mere millimeters. Like a deadly ballerina he spun and pirouetted to escape her broad sword.
>"You WILL stop insulting me! I am NOT a horse! Horses are ugly! I'm the most beautiful pony your sorry eyes will ever behold, so you should be thankful!" boasted Fluttershy as she slashed and thrust at Anon.
Gaining some distance, Anon clenched his fists and summoned his mighty chi. "SOOOOooooOOOOooooOOOOWAhhhhhhh!" A blast-wave of chi pushed Fluttershy back, crashing her into a pillar and sending her sword with a ringing "CLANG!" to the ground.
>"Ooof!" she exclaimed.
"ABRACADABRA! ALAKAZAAM! PRESTO CHANGO!!!!" said Anon with a rapid succession of enchanted finger signs. Instantly, a shiny steel staff materialized in Anon's hands with a magical "VOIP!" sound. Doing some fancy staff spinning, he snapped into a dramatic fighting stance.
>Fluttershy cringed and rolled her eyes. She should have taken care of business when she had the chance.
>"DAMMIT!" she cursed, knowing that the end was not so close as she thought. "You know, that was ridiculously cliche, Anon. You lack style!"
Anon did some more fancy spinning, popped into another fighting stance, and beckoned her with his fingers to come after him again.
>"Fucking show off." Anon muttered.
>But then something happened. A great sound of thread tearing echoed through the room and Anon's robes fell to the floor with a "FWOOSH!", leaving him standing only in a white loincloth with red heart print pattern.
"WHAT!?" said Anon in pure shock.
>A sinister sneer shone on Fluttershy's face as she took up the broadsword in her aura and moved slowly toward Anon.
>"Did you think I was trying to kill you when I was chasing you around the room just then? You really are clueless. NO! I was just cutting your clothes! I don't want your blood. I WANT YOUR MEASUREMENTS!"
> Then, Fluttershy's face gradually became soft and soothing. With a seductive overtone in her voice she enticed. "Submit, Anon! Submit and all will be forgiven. It's just a few measurements."
>Finally, eyeing his rippling muscles and promising bulge while licking her lips, Fluttershy felt a twinge of sexual lust. "Looking good by the way, Anon! Mmmmmmm! Delicious!"
"Try looking into that place where you dare not look! You'll find me there, staring back at you! All those nightmares you had as a foal. It was me, ANON!"
>Instant rage surged through Fluttershy at Anon's insolence.
>"Despicable scoundrel! Vile swine! Mangy cur! BLAZING CUNT! Just what the ACTUAL FUCK is that philosophical gobbledygook supposed to mean!"
>Fluttershy pointed her sword at Anon and sent metaphorical daggers into him with her eyes.
>"I've had enough of you! Up until now I've been going easy on you, Anon. I've only been using like...7.83% of my power. I'm more powerful than you, Anon, and now your gonna regret it!
"More powerful than me? Oh? How many breads have you eaten in your life?
>"Plenty! I have bread with strawberry jam and tea everyday at lunch with Angel Bunny!" she screamed in response.
>"AAAAAAAAAAHHHHHHHHHH!!!!!!!" she began as she commenced powering up.
"I too have been going easy. I used maybe...7.67% of my power, max!" said Anon with a smirk. His spiky hair began to twitch wildly as he commenced his own power-up. "OOOOOOOOOOHHHHHHHHHH!!!!!!!"
>Both were now enveloped in mystical shinning auras. They glittered and sparkled as they surged with power drawn from the very veins of the universe. Fluttershy's shimmering mane and tail whipped through air as power coursed through them. Anon's hair was waving with unbridled ferocity and emitted great electrical sparks. Their eyes shut in transcendent focus.
>A few hours later...like, ten hours later of solid powering up, both were at maximum power. Each opened their eyelids, but there were no eyes, just pure white light. It was the light of unfathomable, ultimate cosmic destiny!
>Get ready to lose and be utterly humiliated, Anon! When I've cast your ruined carcass to the ground, I'll do as I please with your pee pee!
"It is you who will fail totally yellow pony"
>"That's Empress...or, Fluttershy to you!"
"Very well, but when I unleash the full scope of my immense power you will be only a smoldering husk!" Anon threatened. "And why do you keep calling them 'oblongs'? That is not recognized vernacular! Why not just balls?"
>"Because they're not spherical you raging idiot! They're like, semi-ellipsoidal, so...oblong! Did you fail geometry, or what?"
"I AM THE VERY GREATEST AT GEOMETRY!!!"
>That was the last straw. They rushed at each other with the accumulated power of galaxies. Anon's loincloth was instantly vaporized since no normal material could withstand that level of spiritual pressure.
>As they embraced in combat, beams of energy issued forth from them, blasting gapping holes in Anon's house. Fluttershy's sword and Anon's staff moved at incredible speeds. As the weapons connected, waves of warped space-time propagated outward and contorted the oak beams into bizarre shapes.
"Ho! You are good, but I am better!" said Anon with a grimace.
>Squinting her eyes in hatred, Fluttershy responded, "We shall see! You are a worthy foe but..."
>She could not finish the thought for she was now abruptly distracted by Anon's naked manhood. In her eyes it was majestic.
"Now I have you!" Anon slipped a thrust and landed a blow against her shoulder. Now the blows fell like rain as he pummeled her and she desperately fought to block and evade.
>Fluttershy could not focus her mind, distracted as it was by the flopping flesh shaft that danced before her eyes. It was all she could do to break off and create space between them to pause the fierce melee.
>Panting heavily, Fluttershy coughed, painting the floor crimson with blood. She reached up a fore hoof and wiped away dribbles of blood from her mouth before addressing her foe, who was now standing naked and confident over her.
>"I will have you Anon; you will not win! You are human and so you will ultimately succumb to weakness. GIVE UP!"
"I reject my humanity, Fluttershy! And my weakness with it!"
>Enraged by this, Fluttershy summoned the last of her strength and went for Anon with an exceedingly sharp attack.
>"ASSHOLE! Just give in! AAAAAHHHHH!!!"
Anon parried and blocked, moving back by intention, drawing her into position. Finally, as Fluttershy let loose a powerful thrust, he turned his staff vertical, turned about his spine and leaned out. This allowed her sword to slip past his chest and embed itself in the three foot diameter oak pillar behind him.
>Fluttershy now desperately struggled to free her weapon, but to no avail.
>"Eh! Eh! Eh!" she said helplessly as she tugged at the sword. Her physical and magical strength was sapped.
Meanwhile, Anon had raised his mighty steel staff above his head and was about to send it crashing down. "ZA WARUDO!" The staff impacted the spine of the sword, shattering it catastrophically and sending the hilt clattering pathetically to the floor. "WWWRRRYYYYY!" cried Anon as he spun the staff around and swept Fluttershy off her hoofs. She landed with a thud and an "Ooof!" on the floor while Anon used his monstrous chi to simultaneously pin down her hoofs and retrieve the burly knife he had used to impale her records book earlier. Knife in hand, he dropped to his knees. One knee was on her neck, the other pushed down on the tender nerves in her snoofa, visibly causing her pain. The knife pressed ominously against her neck.
>Fluttershy knew she was finished, but through the terrible pain she felt something else. It was the meaty length of Anon's cock lazily laying across her face and neck. Not allowing herself to be distracted by pain, she began estimating. Based on her knowledge of the dimensions of her face and neck, and accounting for curvature, she produced a reasonable guess. Another sensation now made itself known. Anon's oblongs were resting comfortably in her ear. Judging by the sensation of their weight and pressure on her ear tissue, as well as their heat, she produced another estimate.
>"Approks-amat-ee eleben int-essss wen flast-bid, ahn obongs approks-amat-ee tree poont un ooonces tootal! UNF!!!!"
"Do you yield? YIELD OR BE DESTROYED!" said Anon tersely, as he pressed the knife in and drew a drop of blood.
>"AH YEEL! AH YEEL!"
Anon let her up, picked up his staff, turned it vertical and let the end fall to the floor with a "THUNK!" of finality. "Now leave."
>Yet, Fluttershy would not be deterred. She tried one last attempt.
>Speaking with royal grace, she said, "Anon, your pee pee and oblongs meet and exceed my specifications! Congratulations! You are truly a worthy Anon! Won't you please come back with me and be my sex slave?"
"No!"
>"Oh please?" she said softly and while batting her eyes.
"I said no!"
>"Well...um, would you, er...that is, would you...have sex with my here...I mean, right now? I mean, we'er both...uh, hot and sweaty...I think...it would be nice. Don't you? Please?"
"It will not happen!"
>"...Pretty please?"
"No means no, means no! Go now back to your own dimension!"
>Rage now welled back up.
>"Fine! I'll go! But I'll be back! Sooner or later you will be mine Anon. I will be your master! In time, Anon. In time."
>Taking a breath, she continued angrily while opening an inter-dimensional portal, "YOU WILL SMASH MY OVARIES WITH YOUR MEAT! I WILL HAVE YOUR SUCCULENT...VERY LARGE...CUM FILLED OBLONGS IN MY MOUTH! AND...AND YOU WILL RUB MY TUM TUM ALL OVER WITH YOUR PEE PEE!"
"BEGONE!" yelled Anon as he thunked the end of his staff into the floor once more.
>Taking a cunning tone of voice, Fluttershy's face became contorted with a wily grin. "I'll find your fetish Anon! Then you won't be able to resist! What is it! Tell me. Is it lingerie, hoof-jobs, dress-up, role-play? Tell me!"
"You will never know the depth and power of my fetish! My testicles will never have you as their master!" said Anon with an outstretched, upturned, and clenched fist.
>"I'll find it! You'll see!"
"The more carefully you scheme, the more unexpected events come along!"
>Fluttershy rolled her eyes at Anon's meaningless philosophizing.
>"Hmph!" said Fluttershy as she turned her chin up in the air and stepped through the portal, closing it behind her.
"Dammit! Now I have a lot of repair work to do to this place" said Anon, looking around.
>On the other side of the portal, Fluttershy was frustrated at her failure to capture and rape Anon, but she was giddy that she had finally found an Anon that was worthy.
>"Finally, I have found him! And it's only a matter of time before I find his fetish and make him mine for ever! I would have sex with him at least twice a day, and hug him, and pet him, and squeeze him! The mathematicians were correct! I must reward them to produce more and greater results. They shall have the most choice mare pussy in abundance!" >Then with quiet pondering to her self, "What is your fetish Anon? What is it?"
