Yellow & Blue: A Tragic Tale of Friendship

She was flying blind in a storm cloud, no longer sure which way was up or down, east or west. Her muzzle and flanks were rubbed raw by stinging rain. She couldn’t remember where she was going or why; all she knew was she had to keep flying.

A sudden gust threw her downward, and she could see the ground rising to break her out-of-control fall. She tried to spread her wings to slow her descent, but the cloud had become as thick as appleberry jam and she could barely move them. Any minute now she would crash into the ground and her body would be broken into a hundred pieces and nopony would come to pick them up. She looked at the ground again, and now saw it covered by hundreds of yellow and pink bunnies, all with Fluttershy’s kind, loving face. I’m having another nightmare, she realized. Wake up, wake up! She fought her way to consciousness and opened her eyes to reassure herself that she was at home, safe in her bed.

And the light of a thousand suns exploded in Rainbow Dash’s brain.

Her eyes, closed for days, were not prepared for high noon. She slammed her eyes shut again and turned away, feeling as though somepony had kicked her in the forehead. But she found she could only turn her head a little way before it stopped.

"Ah, the one and only killer of clouds and destroyer of friendships, Rainbow Dash, has awoken." Rainbow tried to locate my voice, but she was still blinded by the light.

"Who’s there? Where am I? What's happened to me?"  She tried to step forward, but her legs wouldn’t go. "Why can't I move?"

I stood off to the side, out of sight. "That’s a complicated question, Miss Dash; one that we will have many days to discuss. The short answer is that you are lashed to a sturdy wooden frame, way out in the woods where nopony will ever find us. I’ve built torture racks like this for human women, but you’re the first mare I’ve abused this way; I hope it’s uncomfortable enough for you.” I gave a little chuckle. “And the long answer? Well, let's just say I'm a twisted sadist who likes to screw with pony's minds, figuratively, and bodies, literally."

Rainbow was still groggy but she knew she was in trouble. She opened her eyes a little and saw she was in a forest clearing. There were large boxes strewn about as well as a table and a small tent. Under her she could just make out the edges of the wooden form she was lashed to. She threw herself backwards and forwards, but her hooves were securely tied and her thrashings barely budged it. She tried flapping her wings, but she found they were also tied down. "Let me go, you asshole!" she yelled, throwing herself again and again. "Let me go let me go let me go!"

After about five minutes she wore herself out. She hung loosely in the frame, out of breath. “Girl, if you get all sweaty this wash will turn you six different shades of white.” I dipped the brush back into the pail and resumed scrubbing her flank. “Besides,” I added as I wrinkled my nose, “I want to get this over with; this bleach stinks.” She threw her head against the restraints, trying to see what I was doing.

“What’s going to be white? What are you doing? What are you brushing me with? Let me GO!” she yelled, fear evident in her voice.

I realized that increasing her agony would help pass the time. I rummaged around in one of the boxes for a small mirror. I stood in front Rainbow and slowly angled it so she could see my handiwork. “ARHHHHH!” she screamed. “What have you done to my beautiful blue coat?” The once sleek, azure pony flank was stained by a huge splotch of dirty white almost three feet across. Droplets of pale bluish liquid slowly dripped off her underside. She screamed, but no words could adequately express her horror.

“Oh, but that’s not the best part. Look at this, Rainbow.” I angled the mirror so she could see farther down her body.

“My cutie marks!" she shrieked. "Oh my god! Oh my God! What did you do to my cutie marks?" Discolored rectangles on her haunches were all that remained of her cloud and lightning bolt insignia. She tried to speak but nothing came out of her mouth; the waterfall of tears said everything I needed to know.

"You mean this old thing?" I walked over to the work table and held aloft a scrap of horse hide bearing the faint outline of a storm cloud and lightning bolt. Her mouth hung open, too horrified to speak. "Don't worry. I made a few test cuts, and your magic pony hide will grow back and not even show a scar. But without this, of course." I gave her birthright a playful shake and set it back down. A high-pitched wail broken by choking sobs rang out over the trees.

"Don't worry, girl,” I said condescendingly as I patted her side. “I'll make you an new cutie mark, one to go with the new personality I am going to give you." Unconsoled, her sobbing continued unabated, although she was able insert a few swear words.

I took a syringe off the table and stabbed it into the midpoint of the stubble that used to be her multicolored mane. She yelped while I slowly depressed the plunger. "Honey, you need to stand still or it's just going to hurt more. I’ve have to get this pesky mop started before I finish scrubbing the color out of your coat." The injection of the combined white dye, hair growth tonic, and a few special ingredients would erase the rainbow colors that bound her to her old life of bitchiness and cruelty. Her mane, and the rest of her body, would become as white as the fallen snow. I refilled the syringe and speared it a fraction of an inch farther along her neck. She winced and tried to pull away, but the frame held my prisoner immobile as I speared her again and again.

This process went on for several more hours until I couldn’t stand any more. We were both exhausted; my hands and back ached from the scrubbing and stretching to reach her mane. Rainbow was beyond tired. She didn’t even try to hold her head up any longer. Days of being strapped motionless in the frame, the stress and pain of the transformation, and constant sobbing had sapped all her strength.

Rainbow eagerly accepted my offer of apple juice and a couple pastries. I made myself a “courage potion” of apple juice with a little whisky and sat down to rest my legs. Now, at her most vulnerable, it was time to begin the head-games.

"Rainbow, earlier you asked why you were here." Her head hung limply in the frame, and she barely turned an ear in my direction. I tossed a pebble at her flank to get her attention. She flinched and slowly turned her head in my direction. "Rainbow, you are my prisoner for two reasons. First, I like tying up mares and then fucking them, and conveniently," I gave her a hungry, predatory smile, "you're a mare. Secondly you have become a horrible creature, destroying friendships and taking advantage of people who care about you. You were not always like this. I watched you when you were younger. You and your five best marefriends had thrilling adventures and fun together. The Mane Six would do anything for each other because you all understood the true meaning of friendship.”

“And when it came to flying... Rainbow Dash was the best; there was nopony better at racing or cloud popping than you." I paused for emphasis, "except the Wonderbolts, who you idolized. You tried out year after year, but you were never quite good enough for them, were you? Only superstars like the Wonderbolts could understand the thrill, the rush that came with being a speedster like yourself. Oh, sure, Fluttershy and the other pegasus ponies could fly too, but to them it was just moving from point A to point B. And when the Wonderbolts finally said they didn’t need you, your whole world fell apart. Your wounded pride consumed you from the inside out."

“If you couldn’t be on top of the world, though, you could certainly live it up on the bottom. You started hanging with a bad crowd and got into joyweed. You alienated everypony who ever liked you and drove a wedge between the best five friends a pony could have. If you couldn’t be happy, there’s no reason for anypony else to be happy is there? But it didn’t matter, because now you had new friends. Friends who loved to party at your place, crash at your place, eat your food, and attend your special sleepovers for all your girlfriends. You even bought a place, in Ponyville, on the ground, so you could have bigger parties for more than just your pegasus friends. Your friends are using you just like you used Fluttershy, and you're too stupid to see it.”

“That's a bunch of crap, you jerk” the blue spitfire shot back. “Nopony's using me for anything! You can’t do this to me! And for the last time I didn't do anything to Fluttershy!”

I ignored her protestations. “When I arrived in Equestria this time I hadn’t decided who my victim was going to be. I mean I knew I was going to humiliate and rape a pony, but I was looking for the right one. When I learned how you destroyed Fluttershy’s life, I knew it was going to be you. You were a two-fer: I could fuck with your pride as well as your body.”

"I didn't do anything to her! She's fine. Let me go!"

I gave her ass a brutal slap and continued my pontificating. “Think of me as your sadistic fairy godpony. My magic wand will touch you and through an excruciatingly painful cosmetic makeover and brainwashing you will become a new pony who is beautiful and kind. And of course somewhere along the way I'll take a few minutes to pound my personal magic wand up your asshole. Doesn't that sound like fun?” Her thrashing and kicking told me she wasn’t nuts about the idea. Good.

“And how do I have all this secret knowledge about you and Fluttershy?” I dug around in my pocket and pulled out the key that would unlock Rainbow's great adventure. "This is a memory amulet. When you turn it one way it records the thoughts and feelings of the person who is wearing it; but if you turn it the other way, you experience the thoughts and feelings recorded in it.”

“Pinkie told me stories about your very popular mares-only parties. I got curious so I loaned this to Fluttershy before she went to your last sleepover."

Rainbow raised an eyebrow. "What of it?"

I gazed thoughtfully into the amulet. "I don't think Fluttershy has a very good time at the sleepovers, do you?"

"What do you mean?" asked Rainbow. "She always has a good time. She shows up for every party. Yea, sometimes we might be a little rough with her, but she's a big girl. Nopony forces her come to the sleepovers. Besides, I think a shy girl like her needs to get out and have some fun. I’m doing her a favor by inviting her."

"From what I’ve seen in the amulet, most of Fluttershy’s “fun” is spent with her head wedged between some mare’s thighs, with you cheering her on. Is that the kind of fun an emotionally wounded pony needs to be having?”

Rainbow's eyes got very wide. "Oh, yes, I know what goes on at the sleepovers." I waved the amulet in front of her. "And I know what Fluttershy does at the sleepovers, and how many times she does it, and who she does it to. And I also know," I got down in her face, "the reason she does it. She does it for friendship, Rainbow." I poked her in the forehead for emphasis. "Your friendship, Rainbow." I poked her again, harder. She winced. "Friendship is supposed to be important to you ponies. Right?”

"Me, I'm an asshole. Everybody knows I'm an asshole so they don't get their feelings hurt when I treat them like shit."

I let my expression soften. "But Fluttershy is a gentle soul that needs friends. So when you say you're her friend, she wants to believe you. And if you ask, she'll do anything for you to keep you her friend. You've been abusing your little friend-slave for so long that neither of you recognize it anymore. You've become an asshole without knowing it, Rainbow, so I’m going to show you."

I held out the necklace in front of her muzzle. "Get that thing away from me," she said.

I slipped the chain over her head and she snapped at me, but the frame held her just out of reach. I gave her a stinging slap across the face. "You try that again and you’ll spend your next life wearing fucking polka dots, you hear me?"

I slid the necklace the rest of the way down her neck and turned the amulet to "play".

Rainbow froze, and her eyes became unfocused. As long as the necklace hung around her neck, every moment of that soul-crushing night would play again and again. With no way to escape, Rainbow was forced to watch, and relive, every minute of pain and abuse and rejection that was Fluttershy's life.

A tear trickled down Rainbow Dash's cheek.

I smiled, and started scrubbing the other flank. The water in the bucket was getting pretty blue. Time to change it.

************

The cartoon sun blinded me as I stepped out of the portal. High grass reached up to my knees as I dragged my trunks out of the opening. I didn’t want to think about what might happen if the portal closed before I could get everything out.

The last time I was here, Twilight Sparkle and I had a once-in-a-lifetime "hookup". I had found a long-lost magical necklace in the basement of the castle. The magic books said it was netherstone, a rare, dangerous gem which absorbed a pony’s magical and life energy when worn around the neck.

It's perverted as hell, but these uber-cute cartoon ponies with their little noses, big anime eyes and even bigger, rounded, fuckable pony asses were adorably hot. I arranged a secret rendezvous with Twilight far from the crowded city. There I presented her the necklace, and after her strength ebbed I gave her a skull-fucking neither of us would forget. I took the necklace with me when I went home, just in case I ever had chance to give another pony a "special gift." I left Twilight and her sperm-drooling lips lying in a field, unconscious, but I figured with the necklace removed she would recover. I was, after all, a rapist, not a murderer.

I had set up camp and was cautiously exploring when I came across a small house just off the road. Above it hung a worn sign reading “Trixellina, Master Magician, Weaver of Spells and Incantations, Thaumaturgistical Scholar, Enchanter of Wards for Health, Love, Safety.” The print got a bit small at the end. I knocked on the door and it opened revealing a blue mare garbed in a cape and wizard’s hat. Once she got over the shock of seeing a human, I invited myself in for a long talk with a very interesting pony.

The former traveling-circus con-artist brought me up to speed on the Twilight situation. Rainbow Dash had found the catatonic mare wandering aimlessly after our fantastic, forced, face-fuck. The Princess made up some bullshit story about how Twilight had saved Equestria from an evil unicorn pony but had suffered a terrible magical wound and had been sent to another kingdom that had wizards who could cure her. It sounded like Princess Celestia opted for a cover up. But happy, happy pony land was so happy, happy that everypony got over it in a month or so, and nopony was suspicious when she never came back.

I looked through the few baubles she had for sale, and something called a memory amulet caught my eye. Trixie explained that it recorded the thoughts and feelings of the wearer. There was a record setting and a play setting, and you could even fast forward as the images appeared in your mind. It was pretty expensive, and all I had to barter with was the netherstone necklace I had used on Twilight. It was obvious that she knew exactly what it was as I pulled it from my pocket. Her poker face fell, and her eyes narrowed to that dangerous, hungry look usually reserved for crack addicts and coupon shoppers.

Without taking her gaze off my necklace, she said in a forced, non-chalant way. "So what do you say, even trade?"

Time spent haggling was time spent not screwing ponies, so I agreed. "Sold!" She snatched the netherstone necklace from my hand.

Immediately she planted her muzzle in my back and shoved me out the door. "Store Closed. All sales final! Have a nice day!" she barked out even before I hit the ground. I opened my fist to confirm that I still had the memory amulet, just as the front door was slammed shut.

With Twilight out of the picture I was free to move about the countryside. My goal, as always, was to score some soft, rounded pony ass and then get back to the portal. But who would be my next victim?

Last time I was here, one evening I noticed about half the mares in town were absent. Pinkie Pie told me that most of them  were at a sleepover at Rainbow Dash’s. I pressed Pinkie for more details, and although she was completely oblivious to the obvious, there was a little female pony fun festival going on. Unfortunately I had to leave Equestria last time before I could investigate. But I was back, and with the help of my new magical toy, I could discover what kind of pony perversions went on behind closed stable doors. All I needed was a way to get the amulet into the party. It seemed that Fluttershy was Rainbow’s best friend, so she was the place to start.

I wandered into town, attracting quite a crowd as I’d expected.

It was fun being the center of attention. Half the ponies in town came to see me holding court at the fountain. As I was chatting up everypony in town, I spotted Fluttershy at the far edge of the group. I answered about five more minutes of "Are there girl humans?" and "Why do you wear clothes?" "Do any of your horses fly?" type questions and excused myself. I made my way back to where Fluttershy was standing and said in my friendliest, quietest, least intimidating voice "Hi, Flutter..." and before I could finish she bolted behind the nearest tree.

I coaxed her out and we talked for a while. She was appalled to learn I was sleeping in the forest and said I should stay at her home for as long I needed. That evening she showed me around her house and where everything was. I asked "Aren't you going to bed now?"

She let out a little sigh. "No,” she said, trying to force enthusiasm. “I'm going to a party."

For what I suspected was a pony orgy, she didn't seem very excited. "Wow. Is it at Pinkies?"

"No," she said in a quiet voice, "it's at Rainbow's house. Please don't wait up for me. You are my guest, please sleep on the bed. The rug is very comfortable; I've slept on it many times."

"Wait, Fluttershy. I am so grateful for your generosity and kindness." I pulled the enchanted necklace out of my pocket and held it up to the light. "I would like to loan you, just for tonight, this necklace so you will look extra pretty at the party." I turned the gem to 'record mode' and placed it around her neck.

Tears began streaming down her cheeks. "I would very much like to look pretty for the party." She rubbed her muzzle against me in the pony version of a hug and headed out the door.

Maybe I could make Fluttershy my next victim, I thought, but not until I had a chance to see the home movie of what went on at those sleepovers. I kept imagining her and the other mares taking turns licking each other, playing spanking games, and using carrots as strap-ons. I got so hot thinking about it I had to jerk off, shooting thick globs of cum all over Fluttershy's pillows. I hoped she wouldn’t mind.

I was half asleep when I heard the door open and close quietly. I guessed it was probably seven or eight o'clock in the morning. She curled up on the rug and softly cried herself to sleep. I'm guessing the party didn't go too well. Later that day I asked for the necklace back, and waited until she left the house on some errands.  I got myself comfortable on the bed, pulled broncobuster out of his holster, and turned the amulet from record to play...

At first the amulet replayed flashes of me giving her the amulet and I felt her happiness and friendship. And then she was walking over to Rainbow’s and I felt a heart-crushing dread. I fast forwarded to the sleepover. And there was a whole room of mares, all in their party clothes. And then there was a suffocating wave of anxiety as they all looked at her as she entered the room. And then she was talking to Carrot Top. And then Carrot Top put a hoof on her head, and then she was between Carrot Top's legs. And then there was a sadness so deep and crushing I almost cried out. And then her face was wet and sticky and Carrot Top smiled at her. And then there was another mare but now two hooves were forcing her down roughly. And then there was Rainbow and she almost said hi. And then there was warmth and the smell of more sex, and then through the night there were more mares and more hooves and more of the smell of sex.

I fast forwarded to a view of sleeping ponies everywhere. It looked like a frathouse after an all-night kegger. And Fluttershy felt so tired and sad.

And then Shutterfly was in Rainbow's bedroom and there was joyweed on the bed and a stoned Rainbow was slowly rubbing herself. And then Fluttershy felt happy. And then Fluttershy was in the bed and then Rainbow gave the yellow pony a wet sloppy tongue kiss. And then Fluttershy returned the kiss with genuine affection.

And then Fluttershy was between her friend's blue legs. And then Rainbow's voice became scary and rough. And then Fluttershy's pink mane was pulled, hard, smashing the yellow face against the blue cunt. And then Fluttershy was scared because she was too close to lick it the way she had been taught and Rainbow might not be happy.

And then Rainbow arched her back and moaned and released her mane. And then Fluttershy was happy that she had made her best friend happy. And then Rainbow grabbed a hoofful of joyweed and offered it to Fluttershy and Fluttershy shook her head and Rainbow packed it into her cheek. And then Rainbow was saying You're the best. And Fluttershy’s heart leapt and her eyes smiled at the reassurance that her friend still liked her. And then Rainbow saw Fluttershy’s expression, and quickly added I mean you're a good friend, and you sure know how to please a pony. And then Rainbow grabbed a towel and started wiping off. And then Fluttershy was filled with anticipation and fear as she cautiously crept up the bed until she was next to Rainbow. And then Rainbow fell to sleep and Fluttershy drifted off, feeling safe and loved. And then it was a few hours later and it was morning and Rainbow was thanking her for coming to the party and being a good sport and being nice to all her friends and invited her to the next one. And then Rainbow disappeared into the bathroom and Fluttershy walked out the front door and got three houses down the street before she started crying.

*****************

"C'mon, slowpoke!" I urged. The bleary-eyed, hungover, blue pegasus pony fluttered along behind me.

"Are we there yet? I need a rest."

"The mighty Rainbow Dash tired? What would the Wonderbolts think?" I goaded her.

We finally got to my camp at the edge of the forest. I had purposefully set it up far from town and my heart was pounding and my legs ached. Trying to keep up with a flying pony was a lot of work. "Well, where is your flying machine?" she asked, looking around. Out of breath I motioned in the direction of the frame I had built, ropes dangling from it in various places. "This flies?" she said incredulously?

"Well, almost; I've still got a little work to do on it."

Rainbow buzzed around it. "A little? I don't see how this could get off the ground!” She buzzed around it a couple more times. “I thought you said your machines didn’t use magic.”

I plopped down on a log, half because I was tired and half because I needed Rainbow to sit down for the next part of the plan. I poured us both some apple juice from my canteen, topped our cups off with whisky from my hip flask. Hers had a lot more "topping off" than mine did.

She stuck her muzzle into the cup and took a sniff. She jerked it away from her nose, a grimace on her face."What is it? It smells funny."

"This is a special courage potion. All the flyers in my world drink it to show how brave they are. It also helps them fly higher and faster."

"But I thought you said you needed machines to fly."

I ignored her and took the cup back. "But I'm not sure it would be safe for a little pegasus like you. Now if you were as big as the mighty Wonderbolts..."

Rainbow snatched the cup out of my hand and swallowed the whole contents in three gulps. "Fuck the Wonderbolts. Fuck 'em all." Always courteous, I refilled her cup with more courage potion.

We sat and stared at the clouds. I had a pleasant little buzz, and it was fun watching Rainbow try to appear cool and at the same time not fall off the log. I figured another five minutes and she’d be out cold.

"You know, Rainbow, I know some things about you. For example, I know you're not a very nice person,” I paused waiting for the insult to permeate the scotch whiskey fog. “Most of the people in the town say you used to be nice, but now you’re a jerk. They don’t bother inviting you to their parties.”

She finally realized what I was saying. “Wha?” she slurred. “Fuck’em I got my own parties. Don’t need 'em…”

I was getting a little impatient. I pointed up at the sky. “Hey Rainbow, are those the Wonderbolts?” She turned to look and I gave her a shove. She toppled off the log and was out like a light.

******

"What are you going to do to me?" asked the now gleaming-white Rainbow. The physical transformation was complete. If I wanted to crush Rainbow’s spirit, to make her suffer for torturing poor Fluttershy, this was the last chance before I wiped her memory.

“I think you know what this perverted pony-fucking human is going to do to you." I walked along the length of my captive, dragging my fingernail along her side, causing her to wince and yelp as I scraped the tender flesh of her emerging snow-white coat. I caressed the gorgeous white round rump that I had so carefully redecorated. "You really are pretty for a butch dyke asshole pony, you know that?" I cooed. I grabbed her angrily swishing tail and held it up, exposing the soft pony bits beneath. I moved in close and took a deep sniff; pure pony assaulted my nostrils.

"I'm sure you're scared right now, Rainbow. You all are before it starts. And during it you'll be terrified. But I promise it will only be as long as I need it to be, and then we can part company." I slipped out of my pants and broncobuster sprang to attention. "Don't worry, though; in a couple of hours this pony-rape and all the other bad things in your life will be wiped from your memory.”

I pushed my enlarged dick against her brown rosebud and wiggled it around. The tip of my cock was still dry, and my piss hole opened and closed as it was dragged across each ridge of her sphincter. Normally, I don't use lubricant when I'm sodomizing my partner. I want them to experience every agonizing second as their anus surrenders to my attack. But this sweet pony ass was too tender for an all-out assault, and going in without some kind of lubrication would rip out her asshole and half of her rectum.

I spread her white cheeks wide and spit a big wad into her ass crack. "What are you doing?" Rainbow shrieked in surprise.

"I am being a gentleman, my dear mare. Gentlemen always lubricate an asshole before they violate it; you’re lucky I’m feeling like a gentleman today." I grabbed broncobuster and rubbed him up and down her white valley, making her butthole wet and shiny.

"No! What are you doing back there? Stop playing with my butt!" she said frantically. She pulled and twisted against the ropes but she and her beautiful pony ass weren't going to escape me. I pushed against her, trying to widen the doorway to my happy dreams. Her anus was being a stubborn little bitch, just like her.

"C'mon, Rainbow, just loosen up a little for your friend."

"No! Stop! It hurts! Stop Stop!" screamed Rainbow.

"Rainbow, calm down. It may feel like it, but I am not trying to kill you." I pushed a little harder and she winced. "This is something big girls do for fun in the human world." Mostly true, I told myself, but in the human world the big girls only do it if you pay them four-fifty in cash, plus another hundred for the motel room. "So you should be proud that you are the first pony in all of Equestria to get fucked up the ass. Trust me, when word of this gets around you will be very popular with the stallions!"

I needed her to relax. "Rainbow, just pretend you're taking a nice quiet poop in the woods. There's nopony around; you're just squatting and taking a nice little pony poop. Just think about opening up for that poop." I watched her asshole spasm as she tried to relax her sphincter. I pressed the swollen head against her brown star, and gently pushed but her anus stayed clenched tight. "The sooner you loosen up the sooner we can get this over with. C'mon, think about that nice relaxing pony poop in the woods." After about a minute of wiggling I felt her butt cheeks loosen and my cock slid inside, burying itself deep in the ass of a blue cartoon pony.

She howled in pain.

Now that my man-meat was finally stuffed in Rainbow’s poop-hole, I could get down to serious fudge packing. I fucked her hindquarters hard, again and again. Ass sex is too primal, too violent for me to last long. I pounded against her, each lunge throwing her against the frame she was bound to. I fucked her pony asshole like I have never fucked a human's before or since. I was only at it a couple of minutes before the first warning message from my dick arrived, signaling things were moving faster than I had wanted. Shit. Yes, I wish it could have gone on forever, but I could count the whole adventure a success having planted my dick in the ass of a talking pony.

The second warning message was my balls tightening and my cockknob swelling in anticipation of release. I switched to fast, shallow fuckstrokes, trying to get as many in as possible in the seconds left. I held her haunches in a vise-like grip as I jack-hammered her asshole. This was the home stretch of a race I would never be able to run again.

Finally I felt the boiling sensation as my sperm geyser erupted. I buried my cock deep into her bowels, and it vomited load after load of human cum up her pony ass. Like some great anal artist I swiveled my hips, painting the inside of her rectum with my seed. Blast after blast cascaded into her. She moaned in pain as I continued my little thrustings, trying to pack as much of my semen inside her as possible. The herbal supplements I had been taking were definitely working, as there seemed to be no end to the hot goo that was pouring forth from my balls. Again and again Rainbow howled in pain, and I answered each cry by grinding my cock root harder against her raw, swollen anus.

I love these little ponies. They are so innocent and gullible, and when they cry they mean it from the heart. They have never known pain or betrayal until I force my cock into one of their tight horsey-holes. The first time is the most delicious, when you stand over them and see the terror in their huge, soft anime eyes. I wasn't sure whether I liked the experience more or less because this bitch deserved it.

I felt my balls dump the last of their thick cream into her polluted bowels. Unlike my four hundred and fifty dollar 'big girl,' this one didn't give herself an enema before we got down to business. I pulled out and looked at my dick, streaked with brown bowel pudding. Yuk. The fact that I was off-put by the messiness told me that I was out of practice and I needed to have ass sex more regularly. I left Rainbow sobbing while I went to wash off.

*************

I started down the back side of the ridge, muddy and bough-strewn from last night’s heavy thunderstorm. Several times a week I snuck into town to buy supplies, and then had to drag a burlap sack three miles back to camp. Rainbow was almost finished, so this would be last load I would have to haul through the cartoon forest. Hallelujah.

I didn't want to leave Rainbow alone before her transformation was complete, but the work went longer than I had planned and our growling bellies necessitated this last run into town. I as waited out last night's rain inside an abandoned barn, I marveled at the job I had done: the blue bitch was now a gleaming white pegasus pony, not a hint of the pony she used to be. To complete the transformation I had given her the first dose of the amnesia potion Zecora had showed me how to make. By the end of that day she had already forgotten her name and her career as a flyer. The next dose would make her mind an empty vessel, ready to be filled with my own emotionally-twisted, morally-corrupt version of the perfect pony.

When I rounded the bend, I froze: she was gone. In the previous night's storm a big pine tree had blown over. It just missed killing Rainbow outright, but the heavy boughs had destroyed the frame Rainbow was lashed to. I frantically searched through scattered equipment and bits of splintered wood, but it was obvious she was gone. I panicked, running around the camp and forest yelling her name. I climbed to the top of the cliff and spotted muddy hoof prints that stopped, or rather didn’t stop, at the ledge. The storm was still visible off in the distance. I carefully looked down the sheer drop. No dead pony. That could only mean that in her weakened, addled state she had managed to fly out of here.

Shit.

She would soon discover the special parting gift I had left her, or rather taken from her. Memory or not, her uncanny flying ability would be sure to attract attention. To ensure the total destruction of the monster known as Rainbow, I had made a series of tiny incisions into her wing joint while she was passed out. The resulting scar tissue would make any fast or long distance flying very painful, so her days as an acrobatic aerial speedster were over.

Although she had escaped, I knew she wouldn’t get far. With her memory gone, she wouldn't know which direction to go. And if any of the old, stubborn Rainbow was left, she wouldn't rest for a minute, just going and going until every last bit of energy was gone, eventually blacking out from exhaustion and then plummeting to the ground. Somewhere out there was a small crater surrounded by white feathers and pony entrails.

What a fucking waste.

Worst of all, I hadn't finished the mental conditioning. I had planned all kind of delicious manias and phobias and compulsions and fetishes for my creation. My favorite was to be a mental block that wouldn’t let her orgasm unless three or more stallions were watching. I had erased all memories of her past, her friends, and even me (luckily), but I been robbed of the chance to give her a whole new personality. That was something truly evil that I had been looking forward to.

There was no reason to stay any longer, and since I couldn’t be absolutely sure that she wasn’t dead, it seemed like a double good time to leave. I began picking up all of my equipment, not wanting to leave a mess behind. I may be a pony pervert, but I'm not a litterer.
