Luna Grows a Penis.

by Steventheman

First published

Luna expands moon to a feature length diameter.

When Luna finds a book that really should've been burned, she uses a spell - And ends up with a massive dick and Anti-Social Personality Disorder. Couple that with a magic herb that makes the user extremely horny, and couple that with Celestia being the closest thing with a pulse, and fun ensues.

Contains poorly justified futa, Princest, rape, more rape, lots of rape, wounding, murder, chaos, using tears and blood as lube, too much cum, and lots and lots of rape. Like seriously, there's a hefty amount of rape.

OH FUG :DDDDD

Princess Luna gracefully strolled around the castle. The day had been pleasant so far. No major international incidents. World War Four hadn’t broken out yet. No batshit insane senators planning any schemes, and certainly no nuclear-capable mech hijackings. Today was pretty good.

“Celestia?” Luna called out. “Dear sister, where are you?”

There was no response,

Luna peeked around the corner into the private library. There was no Celestia there, but there was a fresh cup of tea. Which meant it obviously belonged to Luna. Finders keepers and all that.

Luna settled down at the table and examined the book left open. It appeared to be an advanced magic book. Luna turned the book to see the cover.

“Spelles of Thee Moste Fuckededous Upedoss: Thine Compendium of Thee Beste Tricks and Trapes to Make Fooles Of Thine Kinsponies and Thy Friendes: Part the Fourthe - Spelles of a Lewde Nature”

Luna was very curious now, so she turned to a random page.

“For the pranklorde withe a complexe moste vile, thise hex will provide literally days of fun and merriment - FOR YOU. Simply recite the spelle listed belowe and soone you will possess the weapon of both God and stallione - The mighty towere of Patriarchy! Thou shalt have a greatsword of sexual might! A giante meaty penis in whiche to dominate even the moste unwilling! They shalt complain most annoyingly about thine male privilege, but thou may clog thy mouths with schlong!”

Luna was extremely curious now. She had always wanted to possess a weapon of God, and had always wished to silence the detractors of the Royal Family by clogging their mouths with schlong. Celestia had warned her about “free speech” and, as Luna put it: “Muh Constitution” but Luna did not give a royal fuck about that. Plebs weren’t supposed to have rights anyway and it was foolish to think that. Commoners were supposed to be ruled and controlled and any dissent destroyed - That was what the whole incident a thousand years ago was over.

With that incident hot in Luna’s mind, she took a big gulp of the tea and read the spell while warming up her horn for magic.

“Oculous Cocktoculous, Fuck Thy Police, Ravioli Ravioli give me the benis. Row Row The Boat, Do a Battle Roll and You Just Lost Thy Game,” Luna recited, before noticing an effect almost immediately.

Luna felt a growth, and looked down. Instead of the usual vagina, there was now quite a large penis and a heavy set of balls. Luna examined the new genitalia while sipping the tea. The tea had a strange taste to it. Bitter, like the tears of a widow. Luna had heard of a herb that tasted like a widow’s tears before. It was called some name like “Pretiosum Succis Corporis” or some other name like that. Luna slapped the penis around a bit.

“So how do I work this? How do you operate a penis?”
“LUNA!” Celestia cried out, running towards her sister. “What have you done?”
“I grew a penis, dear sister!” Luna replied cheerfully. “How do I work this?”

Celestia facehoofed, before noticing the tea was gone.

“Luna...did you drink the tea?”
“Yes,” Luna replied, before feeling her brain go weird. Two things happened: She lost all sense of empathy. And now she was fully erect.

Celestia shook her head. “I guess I will have to call a guard to deal with this. That spell only goes away after you run out of semen.”
Luna grinned, and used her telekinesis to lock the door. “Oh no, dear sister. I won’t need a guard.”
Celestia’s expression turned to slight worry. “I know exactly what you’re implying, and no. No I will not.”
“But-”
“I’m not draining your balls for you Luna. You will have sex with a loyal guard. I mean, I’m your sister, and sisters don’t do that...with each other, anyway. Back in the old times you had to keep wealth in the family. But then Prince Blueblood came about and that’s why incest is now illegal.”

Luna did not look impressed.

( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)


Despite Celestia’s protests about “muh consent” and “muh law,” she was quickly over the table. One leg was already broken into several pieces due to the force of Luna’s cockslap. Her face stung with both tears and acidic pre-cum. She couldn’t believe that this was how she died. Not in a grand battle, not in bed surrounded by loving family and friends. No. Raped to death in a private study by her little sister. Seriously, she didn’t see it coming.

“Onee-sama~” Luna purred. “Is of time for rape.”
“Luna, no...please,” Celestia begged.
“Bite the pillow, onee-sama,” Luna growled. “I’m going in dry.”

Luna put her hips back as far as possible, before thrusting forwards with her rod of lordly might. The howl from Celestia pierced dimensions, causing a spaceship to crash somewhere.

“I didn’t even put the tip in, you giant fucking pussy,” Luna complained. “I missed.”

Celestia only continued crying, wondering why nopony had heard her. That’s when it actually went in. The acid burnt her insides as they struggled to adjust to the intrusion the size of Nazi Germany’s armies. Eventually, much like France, they surrendered, giving little resistance to the invader. And much like France, Celestia was hoping somepony else would save her. But no help was on it’s way, for the Royal Guard’s union had declared a strike action on this day. They were all outside, crowded around a burning barrel, drinking tea and generally not doing much complaining but they all just wanted a break.

So Celestia was fucked. Literally.

“Luna...” Celestia sobbed. “Please...please stop.”

Luna leaned close to Celestia and licked her tears from her face, continuing her relentless assault on Vagina Fortress.

“Cry some more, I find that really attractive, onee-sama,” Luna mocked. She continued bucking back and forth, before wincing a little from the friction. Looking down at Celestia, she noticed the smell of burning flesh and how some areas of the vaginal entrance were charred. She must have been fucking Celestia so fast that she combusted.

“Oh dear,” Luna said. She scooped up some tears from Celestia’s face, before pouring them on the burned areas. The tears sizzled on the wounds, some of it turning to steam. Blood bubbled from the wounds.

Celestia remained silent. She had no words to say to being raped by her sister, using tears and blood for lubricant. The burning of the acid pre-cum tore her insides, while the burning of the friction and hot steam burned her marehood. Blistering. Cooking. Melting. She could feel the penis pulse inside her, not caring what organs it destroyed in its death march to orgasm. To cumming inside her - To making her pregnant with her own sister’s child. Celestia tried to remember all the abortion spells she knew, but couldn’t focus due to an inconvenient case of being violently raped. Celestia tried to reason with herself that it happened to the best of ponies, but she was basically a Goddess - Or that was what she paid public relations to say. In actuality she had about the same level of power as a Third World dictator.

Luna kept thrusting, breathing heavily as she approached her limit. She felt her penis thrash, wanting to vomit out its hot load of sticky life fluid into Celestia’s totally willing womb...Or her kidneys, Luna wasn’t exactly sure which organ she was fucking.

“Luna...please...don’t...not inside, senpai...” Celestia pleaded.

Luna grinned. “In the name of the Moon, I will punish you!”

Celestia cringed as a bolt of cum shot through her. At that moment, her organs were JFK’s brains and Luna’s penis was Oswald’s rifle. And much like what happened on that fateful Dallas afternoon, Celestia’s organs tore apart as she realised she was pretty much doing to die now. It felt bad.

Luna panted and inspected her handiwork. Blood, cum and piss poured out of Celestia’s marehood. The Solar Princess cried softly. Her lungs were now pregnant. But at least Luna didn’t go for the Forbidden Zone. Celestia thought to herself.

“I’m going to impregnate your asspussy,” Luna stated matter-of-factly, examining the target for the surgical strike of her JDAM-sized dong.

Fuck. Celestia thought.

Luna lined up her assault column for the rear assault on the Ass City. Vagina Fortress fell after repeated assaults and poundings, now it was Ass City’s turn to suffer. Luna inhaled the scent of the blistered labia, and quickly spat on the anal ring of fire. She tilted her head as she contemplated maybe getting a bottle of spaghetti sauce to lube up.

“If you’re gonna do it...just do it...” Celestia sighed in defeat. “You win Luna. Just let it end quickly.”

Luna rolled her eyes. “Coward. If you’re just going to lie there and bitch, you may as well enjoy it.”

Celestia only gave a sharp sob in response.

Luna prepared for the final battle. “Penis Thrust Power! Activate!”

The battering ram hit the door, breaking it in one hit. The anal sphincter snapped open with a twang, causing blood to spray all over Luna’s crotch. Luna laughed as Celestia screamed so loud her vocal cords went on strike, citing “unreasonable working conditions” as the reason for their walkout. Celestia watched as her vocal cords physically displaced themselves from her body and camped out on the desk in front of her, crowded around a burning barrel with signs stating that Celestia is a cruel boss and that they cannot be expected to work in such dangerous conditions without adequate pay and personal protective equipment.

Celestia screamed silently as her digestive system completely exploded. She was officially butthurt. Anally annihilated. Shitter shattered. Prostate penetrated. Booty blasted. It was an absolute colon catastrophe. A rectal ravaging. A prolapse party.

Luna gritted her teeth and plunged further into the ruined sack of meat that was her elder sister. Celestia had given up. Her hope had gone the way of most of her blood and poop - Out her ass.

Luna continued fucking, before a second cumshot rang out. It speared right through Celestia’s spine.

Celestia suddenly felt all sensation from her back end disappear. She was a paralysed, raped-out, dying mess of a pony. All her life had led up to this. It sucked. Celestia continued to silently scream due to her paralysis, but it was all for naught. The vocal cords would not end their display of socialism.

Luna felt her balls become much lighter. She had maybe one more shot left in her. She intended to make this one count.

“Sister, today is the first day of the end of your life,” Luna mocked. She watched Celestia’s red eyes follow her over to the table where the tea sat. Luna picked up the saucer and smashed it into jagged edges. “I intend to ensure you go out with a bang, so to speak. You must be honored - You get to die providing me pleasure. And we all know what a selfless sister you are.”

Celestia just shed more tears. She would be lying if she didn’t admit that she wanted death now.

“I love you, dear sister,” Luna smiled, before sending the jagged ceramic shard into Celestia’s throat. The solar princess tried to scream, but could only choke on her own blood. Luna could not help but be reminded of that one video of the Russian soldiers getting executed in Dagestan.

Finally, the opening was large enough. This was going to be the ultimate deepthroat.

Luna lined up her weapon of mass erection towards the gushing neckhole. Celestia continued to choke on her blood, wondering how she wasn’t dead yet. It was surely a most cruel God who watched this hideous display while presumably masturbating furiously while maintaining eye contact with the family dog. Only Illuminati mystics did that.

“Oh fuck yes!” Luna cried out.

“Gargulefbdhgfjds” Celestia replied.

Luna thrust her purple pony penis harder. The flesh of the receiver tore open wider. Despite only just starting her final assault, Luna felt ready to climax already. She kept thrusting, but an acute realisation that her life would be empty after this set in. After doing this, there would be no more worlds to conquer.

Luna was at her peak right here. There was only one thing left to do.

Celestia’s tears stopped being shed, her brain choosing to conserve its final resources on not dying despite Celestia’s wish that she just fucking die already.

Luna emboldened herself for the last cumshot of her life, and as she felt her cock be overwhelmed with pleasure, she pulled out and aimed her gargantuan futa penis at her chin. When the cumshot rang out, it went straight through Luna’s brain, splattering it on the wall behind her. The Lunar Princess collapsed on the floor, twitching, before finally settling when her brain died properly.

Celestia watched the scene through her fading vision, wondering how she was still alive, before looking up, only to see the meaty member fall onto her head, smashing it all over the floor.

As both sisters lay on the ground dead, Twilight Sparkle entered through the door and saw the scene.

“What the fuck.”
