Author's Note
Seriously, these ponies are anal experts. Please be careful with the best part of your body. You can hurt yourself or lose stuff up there. 
Drives Bullies Nuts
“Get in here before someone sees you, nerd,” hissed Diamond Tiara, standing out of view as she held her front door open.
“Harmony, DT, it’s not a big deal,” said Sweetie Belle, sauntering in the front door wearing a skin-tight star pattern mini dress and an orange baseball cap. Her hooves were stuffed into a pair of neon pink porn star platform horseshoes, the kind so tall they needed supporting struts along the back. “Everypony knows we’re frenemies now.”
“Not everypony knows you’re our anal slave. There’s no need to announce it to the world,” said Silver Spoon. Both her and Diamond Tiara wore nothing but the most negligible of naughty nighties. “Also: what the hell are you wearing? Did you fall into the clearance rack at Old Neighvy?”
“The uglier the clothes, the more fun to take them off, right?” said Sweetie Belle, doffing her cap and tossing it onto the polished hardwood floor. “You should have seen Rarity’s face when she saw I was going to go out dressed like this. She practically had an aneurysm.”
“You pick that hat up right now!” snapped Diamond Tiara. “Were you raised in a barn?”
“No, that’s Apple Bloom,” said Sweetie Belle, bending over at the hips to scoop up her hat. Diamond Tiara’s place was a perfectly polished McMansion. It gave Sweetie Belle an almost sexual thrill to slob the place up when she was over. She felt air on her pussy as she bent down — she’d obeyed orders and come over here commando. Her dress was so short that even the slightest motion pulled it up her thighs.
“DT, is it just me, or is our ass slave actively trying to get herself punished?” said Silver Spoon. The gray-furred unguligrade anthro pony leaned against her best friend’s side, arms crossed under her monster rack. Diamond Tiara reached over to stroke one of Silver’s pendulous boobs, and Silver returned the gesture. While Silver’s breasts were natural and heavy, hanging from her chest to her navel like over-full water balloons even at the tender age on nineteen, Diamond’s were the same size but fake. An eighteenth birthday gift from Daddy, and never mind why Daddy was so interested in Diamond’s boobs. They floated out nine full inches from her narrow rib cage, the dreaded I-cup, Platonicly round. Neither girl had much by the way of ass, though — not flat, just cute, firm little round cheeks that looked good in tight pants, but were not much fun to spank.
That was what made Sweetie Belle so interesting to them. Flat as a washboard in the chest department, she had cheeks and hips so intense you could pick her out of a crowd by them from half a stadium away. Thighs like tree trunks, if it was a tree with elegantly tapered, tightly muscles curves leading down to tiny little kneecaps.
“Don’t straighten up, ass slut,” said Silver, hooves clicking on the hardwood floor as she walked over to Sweetie’s front side. “You’re going to eat my pussy while DT gets some stuff from the kitchen.”
Diamond stiffened, balloon breasts bouncing. “Oh, I am?”
Silver smirked and pushed her glasses up her nose. “You get to use the stuff first,” she said. “Does that make it okay?”
“I guess,” said Diamond, already on her way to the kitchen. Silver Spoon watched her pert little ass cheeks prance around the corner, while Sweetie Belle licked up the inside of one of her thighs.
Silver Spoon grabbed Sweetie Belle by her fluffy mane and yanked her head up to pussy-level. “Did I ask you to take the guided tour, idiot cunt slave? Lick. My. Pussy.”
Sweetie Belle yelped with pain and delight at the sharp tug in the roots of her hair. She’d been excited on the way over, sure. People looking at her make her wet, and she was well aware her dress didn’t quite cover the lower curve of her ass cheeks. But abuse, verbal and physical, was what really got her going, and Silver’s hair tug made mare goo trickle down the insides of her thighs. She rubbed her short snout against Silver’s fat, smooth, glossy pussy lips, and nuzzled at the sweet upturned double nub of her clit.
“Oh. Oh yeah,” moaned Silver, tangling her fingers in Sweetie’s mane to keep her in place, and playing with one of her own huge gumdrop nipples with the other. “Don’t tease me, you dumb cunt. Lick it hard. Get your fingers in there, too.”
A shiver went down Sweetie Belle’s spine. She ran her hands over Silver’s taut-coated lower body, feeling belly muscles, hip bones, thigh muscles, then quickly moving to more intimate bits before she could get scolded again. She wrapped her lips around Silver’s nub and slid her middle finger slowly into her tight, muscular tunnel. Her other hand dipped between her thighs, scooping up as much thick sticky mare goo as she could, then reached up through Silver’s thigh gap and started stroking her ponut.
“Ouf. Yeah. Oh, you want to put your fingers up my ass? You make me sick. Do it. But I’m going to make you lick them clean when you’re done.” Sweetie wasn’t scared by that prospect — Silver’s colon was so clean you could eat off it, and Sweetie should know.
Lick the clit. Thrust knuckle deep into the cunt, which loosened up quickly and soon needed a second finger. Work fingers slowly into the asshole, balancing the other mare’s craving for sweet anal pleasure with the need not to hurt her most delicate opening. Sweetie Belle was the one who liked pain. It was a complex operation, like walking, chewing gum, and playing the accordion at the same time, and Sweetie Belle soon became lost in her work. So lost, in fact, that when a delivery truck slammed into her ass cheeks she was totally unprepared.
Sweetie’s shriek made the windows vibrate, and could be heard halfway across town. All over Ponyville, exactly nopony looked up from their work, but more than a few blushed — they all knew Sweetie Belle’s screams by type, and this was a ‘that hurt a lot but in a really good way please do it again’ scream.
Diamond raised the wooden cutting board with a handle on the end and brought it down on Sweetie’s ass a second time. The impact rippled through her ass cheeks in a wave up to the small of her back. She hit her a third time, this time so hard that it knocked Sweetie forward. Her face mashed against Silver’s pelvis and knocked her back against the stair post. Sweetie lifted her tail in a magnificent plume, begging for more.
“Harmony on a dildo, DT,” said Silver. “I thought you’d come back with a wooden spoon or something.”
“She’d barely feel it,” said Diamond. “I also brought a rolling pin. And a can of lard.”
“Nasty,” purred Silver, humping her hips against Sweetie Belly’s face.
The next fifteen minutes were a non-stop spankfest for Sweetie. She squealed into Silver’s cunt, three fingers in her pussy up to the knuckles, so deep her fingertips brushed Silver’s foal hatch. She kept working her fingers against Silver’s ponut, but a quick frosting of mare goo wasn’t doing it for that ultra-tight opening and she wasn’t doing much but stroking the outside. Diamond kept laying into Sweetie’s ass with the cutting board, focusing on the muscular curve of the glute for maximum impact, and the cutie marks for maximum humiliation. The initial stinging shock of the impacts gradually transformed into a hot ache whose intensity grew in a cresting arch of sweet, sweet erotic agony.
Silver Spoon came hard, tugging Sweetie forward by the hair, jamming her pulsing clit against her teeth. Sweetie kept licking, kept fingering, mare goo, and spit dripping off her chin. She used the sudden loosening of Silver’s body to jam her middle finger into her ass up to the second knuckle. She locked Silver’s clit between her teeth; kept licking, pushing Silver over the crest of her orgasm and straight into another one. The gray mare’s hips started shaking, the vibrations getting more and more violent as Sweetie kept licking.
“Gah! Ngh! Ngghh!” said Silver, suddenly pushing back at Sweetie’s face by the horn. “Too sensitive!”
Diamond tossed the cutting board up so it spun in midair, then grabbed it by the edge and held it out to Silver Spoon. “You take over spanking this overly stoic bitch. My arm is killing me, and she hasn’t even shed a tear.”
Silver yanked Sweetie’s head to one side by the horn. The motion made Sweetie Belle’s skull ache in a not-fun way. “Yellow,” Sweetie said calmly.
“Everything all right, Nerd?” said Silver, stroking her cheek.
“The horn play. Could you tone it down a little? You earth ponies are pretty strong, and I worry you’ll yank it out of its socket or something.”
Silver put her hand over her mouth. “Oh, I didn’t even think of that.”
Sweetie kissed Silver on the cusp of her slim belly. “Yank my hair if you wanna pull my head around.” Her hips shivered. “Oh, can you imagine the look on Rarity’s face if you managed to pull a handful out!”
Diamond Tiara gave Sweetie’s tail a yank. “Annoying Rarity is your fetish.”
“It really is,” said Sweetie. “Now get back to spanking me. And put your back into it this time. I want to be fucking sobbing”
Silver Spoon gave Sweetie a sharp slap across her snout and switched places with Diamond, who wrapped her arms around the stair rail and cocked her hips out towards Sweetie. Sweetie moaned happily and ran her tongue over the soft, silky pink lips of Diamond’s pussy. Mare goo dribbled on the Sweetie’s snout, and over it onto the floor. “DT, your pussy juice is so yummy,” she purred, then dabbled her tongue in the thick, sweet, musky fluid coming out of her winking cunt. It tasted sweet and salty and creamy and delicious. Pony pussy and cum often tasted sweet, since, as a culture, they really went for the fruits and sweet baked goods, but Diamond’s was especially tasty.
“Best you’ll ever have, you disgusting whore,” moaned Diamond, stroking the edge of Sweetie’s ear. “Brace yourself. Silver’s using a two-handed grip.”
“Oh is she now… Ahhh!” The impact drove her forward, and mashed her snout into Diamond Tiara’s cunt. Sweetie squealed in surprise. Force rippled through her whole lower body. This blow was followed immediately by another just like it, and then another.
Sweetie grabbed Diamond Tiara’s ass to help her balance and gritted her teeth. Tears squirted down her cheeks. This was what she wanted. Silver Spoon spanked her with all her concentrated earth pony might, shaking Sweetie’s broad, sturdy backside down to the bones, turning her rump into a blazing sun of white-hot agony. She screamed into Diamond’s pussy. Diamond, hanging off the banister by her arms, swung her legs up into the air and locked them around Sweetie Belle’s skull. She thrust her slim hips, lodging Sweetie’s snout deep inside her silky, slimy pussy.
Cheek deep in sticky teenage mareflesh, Sweetie wasn’t getting a ton of air. The lack of oxygen, combined with the kitchen implement assault on her fat jiggly ass cheeks, made her feel as if she were leaving her body. She saw herself floating over her body, positioned between the two other mares, bright pink ass rippling like ocean waves on a stormy day. Silver Spoon was winding up, reaching back over her shoulder like she was playing golf but the ball was really, really stubborn. Her colossal tits lagged a half a second behind the twist of her torso, an effect as hypnotic as the wobbling of Sweetie’s own ass.
Sweetie watched Diamond Tiara’s face go slack with orgasmic ecstasy. Fake boobs trembling, she arched her back above the stair rail and clenched her muscular thighs around Sweetie’s head. Roped earth pony thigh muscle trembled. Looking at the blissed-out expression on Diamond’s face made her feel like… oh… oh wow… like… like… her whole insides were trembling. About to explode. No. That sounded gross, but her brain was too foggy to think of another metaphor. She saw her body convulse. Red-tinted cutie marks jolting and jiggling. Mare goo spraying onto Silver Spoon’s lower belly. A flash of blue-white light, and Sweetie had a sensation of floating in infinite space, bathed in light that radiated pure love, pure bliss. The light drew her towards it, but a voice said, “No, little one. Go back! It is not time!”
Another voice, Diamond’s said: “Are you okay, nerd?”
Sweetie Belle blinked as the light in the room dimmed to normal. She lay face down on the floor in a puddle of pussy goop. Diamond and Silver leaned over her, looking concerned.
“That was amazing.” groaned Sweetie. “I almost died.”
“No!” said Silver. “No dying! Your sister is a fucking beast. I don’t want to have to explain that I spanked you to death.”
Sweetie rolled her eyes and groaned. “Oh, come on. Does that mean you’re not going to spank me anymore?”
“No,” said Silver Spoon, tucking the cutting board under her arm, and bending down help Sweetie to her hooves. “It’s on you to not die.”
Diamond Tiara picked up the rolling pin and the tub of lard from where she’d left them on the floor. “I think it’s time we took this party upstairs.”
Sweetie Belle’s ass felt flayed. Wobbling on her hooves, she reached out looking for support, which Silver gave her in the form of a hand on her battered bottom flesh. She put her nose against Silver’s neck, at the line where it joins the angled muscle of the shoulder; inhaled the cumin scent of her sweat. “What’s the rolling pin for, Diamond,” she asked, voice soft. “Are you going to spank me with it, too?”
“Yeah, no. Again: not explaining to Rarity how I broke your hips whacking you with a stone rolling pin. This is going up your ass.”
Sweetie felt Silver Spoon’s body stiffen. “Are you sure that’s safe?” said Silver. “It’s awfully big, and it’s not meant as a sex toy.”
“Don’t worry, I’m an expert,” said Sweetie Belle, her voice jangling with nervous mirth. “Auntie Fluttershy taught me everything she knows.”
“Like Fluttershy’s so tough.”
“When it comes to scary butt fun, she is.”
The three friends walked up the stairs, Diamond and Silver’s wrists crossed over the base of Sweetie’s tail, gripping the red-raw, slab muscled bulk of her ass as she walked. It made her feel warm and safe to be so desired.
“This is so lovely,” said Diamond, stroking Sweetie’s buttock with a spread fingers. “So round, so firm, so fully packed. Spread your legs and let us worship it.”
“Right here?” said Sweetie.
“At the top of the stairs. What’s the hurry? We’ve got all day.”
Sweetie Belle stood at the top of the stairs, legs spread, tail lifted proudly. Four hands caressed her, fingers digging in, kneading, exploring, appreciating. “Oh. Tender. Tender. Gentle!”
“No,” said Silver Spoon. “It’s too fun to squeeze.”
“You hate to see me go, but love to watch me leave, right?” said Sweetie.
“No bitch,” said Silver. “We just love to watch you leave.”
“Speak for yourself,” said Diamond. She nuzzled in between Sweetie’s cheeks. Her tongue drifted over her pussy lips and ponut. Silver’s brutal spanking hadn’t spared her delicate bits, and Diamond's gentle licks were delicious torment.
Sliver nipped Diamond’s ear. “You know what I want to see? I want to see our little slut princess trying to walk with a rolling pin up her ass.”
The fur stood up along Sweetie Belly’s spine at the thought. “Oh. Yes. Please. My ass feels so empty.”
Silver slapped Sweetie’s ass. “No one asked you. Shut your face cunt.”
Sweetie yelped in happy agony; with her ass battered as it was, even Silver’s little love pat — and that was all it was — felt like a searing blow. She reveled in the pain for a moment, and when she was aware of the world around her again, Diamond and Silver were busy oiling up the rolling pin with vegetable shortening. Sweetie Belle licked her lips at the way the thick gray marble roller glistened in the diffuse afternoon light.
“Oh, look at all that lube. That’s gonna go right in,” she purred.
“I hope, not,” said Diamond, scooping up a handful of white grease to rub into Sweetie Belle’s ponut. “I like it when we have to push.”
Diamond’s slick fingers circled the soft plump ring of her ponut, then hooked inside. Sweetie pushed down, opening herself. Diamond pushed her middle and ring finger up, up through the tender ring of muscle, into the delicate rawness of her squeaky-clean insides. Diamond’s fingers slid in and out, massaging the muscle, relaxing it to allow for deeper penetration.
Silver tucked the rolling pin between her thin muscular thighs like a massive, dripping, culinarily useful cock. “How’s she opening up, DT?” she asked, sliding her hands slowly up Sweetie’s leg. From hoof, up the long stretch of her cannon, over the double bend of her knee. Her hands spread apart as they stroked the plump vastness of Sweetie’s right thigh.
“I could use a little help,” said Diamond, struggling to fit a third finger up there.
“Here, let me.” Silver slid her fingers in alongside Diamond’s, hooked and pulled, and Sweet felt herself begin to gape.
Sweetie Belle gripped the banister. Her narrow, rib-ridged chest rose and fell deeply as she felt her friends grope deeper and deeper inside of her. The stretching sensation grew as they added more and more fingers. Then… oh, it felt like the whole world was inside of her. She loved being stretched like this, being open, being filled. Her ass felt strained to bursting — not that he hadn’t taken massive insertions back there, but it’d been a week or two, and she’d tightened up a bit. What was in her? Not the rolling pin; whatever it was squirming. “Harmony, how many fingers do you two have back there?”
The two young mares giggled.
“No, seriously!” said Sweetie. She craned her neck over her shoulder, but the pump curve of her own ass hid the point of penetration. She could see that Diamond and Silver’s whole arms were moving, shoulder to shoulder. She could also see that they looked very pleased with themselves.
“Guess,” purred Diamond.
“Six. Three each.”
“Wrongo!” chimed Silver. “I wish I had my phone. I'd like to see the look on her face.”
“I do!” said Diamond, producing it with her free hand.
“Where were you hiding that?” said Sweetie.
Diamond just smirked and tapped at the screen a few times. “Lemme get some video.”
A shiver went up Sweetie’s spine at the knowledge her ass was being filmed. The thought about her cute little shield cutie mark, that nopony else in the whole world had. She thought about how Diamond was two thumb taps away from sending a video of that ass being abused right to Rarity. The thought made her insides clench in a not-entirely-bad way. A tiny, evil, horny part of her mind wanted her to ask Diamond to post it online. Again.
Diamond slid her phone into Sweetie’s left hand. Sweetie gasped. “Both hands?”
“That’s right, slut.”
Sweetie pressed the play button with a trembling thumb. She bit her lower lip, watching Diamond and Silver’s lube-slicked hands sliding in and out from between her cheeks, just… completely vanishing up there. Round silky white ass cheeks cradling their wrists on either side. She felt them back there still, sliding in and out through her loosened, relaxed ponut, so deep… so deep inside her. It felt so good, feeling so vulnerable, so open, so used.
Diamond licked the jiggling curve of Sweetie’s butt cheek. “Want me to post it to Clophub?”
No no no no “Yes. Just blur the cutie mark,” said Sweetie, handing back the phone. “Look and see how the last one did.”
“Looks like… nine hundred thousand views, 97% upvoted,” said Diamond. “Posting the new one now.”
Sweetie Belle groaned, sliding her hands over her tiny breasts, across her pouty little tummy, and over her fat glossy pussy lips. The thought of all those ponies playing with themselves, watching her ass, cuming into their outstretched hands while looking at her — oh! She pinched her clit, and rammed four fingers up her sopping wet cunt. She could feel her friends' hands moving through the thin wall of flesh between her ass and her pussy, moving, pumping, thrusting.
“Oh, she’s loving this. What a filthy anal whore!” purred Silver.
“Think she’s ready for the rolling pin?” said Diamond.
“Yes! Yes!” gasped Sweetie, two fingers circling her clit fast.
Diamond and Silver popped their hands out of Sweetie’s ass, leaving her gaping. She shivered at the feeling of her insides being open to the air.
“You rolling?” said Silver.
“Boy howdy, check out that gape!” crowed Diamond. “You could park your car in there! The freaks are gonna love this!”
Silver sneered. “’Boy howdy?’ Who are you? Apple Bloom?”
“My intestines are getting cold while you mock and bicker, ladies,” said Sweetie Belle.
She could practically hear the two young mares’ eyes rolling, but she soon felt the slicked-up edge of the rolling pin pressing against her ponut. It was a big one, much thicker than Diamond and Silver’s puny little wrists, and it strained delightfully at Sweetie’s already stretched and aching ponut. Sweetie arched her back and groaned as it pressed inside of her, so thick, so hard, so slippery. It straightened out the fluting and curves of her guts, pressing in relentless and hard like a bulldozer. Sweetie pushed down on her clit, rubbing it ravenously. She fingered her pussy, stroking the rolling pin through her silky wet cunt wall.
“You doing okay, Sweetie?” said Diamond, her voice tight with concern.
“Ah ya ya!” screamed Sweetie. Lower tummy burning, thighs clenching, brain on fire with pleasure.
She pushed down hard on her clit and she came, pussy muscles clenching down on her fingers, ass muscles jamming down on the rolling pin. Pain and pleasure shot up like a bolt through her spine, and exploded in sparkling girl-cum-smelling fireworks out the top of her head. Mare goo squelched up over the knuckles stuffed into her pussy. A second wave of muscle spasms clenched down on the rolling pin so hard it shot out of Sweetie’s ass and down the stairs, thumping the whole way.
“It dented the stairs!” whined Diamond, holding lube-slick hands to her mouth in horror.
“Ab ab ah ah ah!” laughed Sweetie, falling to her double-bent unguligrade knees.
“Your problem, loser,” said Silver Spoon, stroking the edges of Sweetie’s sore, gaping ponut. “Oh, I wanna do something really nasty.”
“Do it,” moaned Sweetie Belle, rubbing her cheek on the carpet. “Whatever it is do it!”
Silver Spoon’s tongue tickled the inside edge of Sweetie’s ponut. “F-fuck…” Sweetie purred. “Yes. It’s so clean in there you could eat off it.”
“I am to test that theory, nerd. You better not be lying,” said Silver, her face so close to Sweetie’s gaping ass that she could feel the other teenage mare’s breath inside her body.
“Or what, you’ll shove a rolling pin up my ass? Lick me. Please. Please!”
Sweetie Belle felt Silver’s small snout pressing into her gaping asshole. Silky silver fur slid against silky inner skin. Silver’s tongue stroked her lovingly, tickling Sweetie deep inside.
“Oh. My. Harmony,” said Diamond, scooping up her phone from the floor and starting another video. “Never run for political office. I will blackmail the shit out of you.”
“Mgo fmuck murfelf,” said Silver. The motion of the other mare’s jaw stretched Sweetie’s bowls. Sweetie knelt on all floors, her frenemy Silver up to her eyeballs in her ass. She could feel her glasses resting on her ass cheeks. Silver groaned into her. Her hand caressed Sweetie’s fat pussy lips, fingers pushing and stretching, and rubbing them. Sweetie’s thighs began to tremble. She listened to Diamond’s hooves going up and down the stairs. “The fuck is this?” she said when she got to the top.
“Silver’s checking to see if she can tell what I had for lunch!” said Sweetie. “Get on your knees in front of me! I wanna make a pony centi…” She found one handle of the rolling pin inside her mouth.
“Don’t you even fucking say it,” said Diamond, gently poking the handle towards the back of Sweetie’s throat. “Damn. I wish I could face fuck you with this without knocking out all your teeth. Maybe I will. Give you a nice smooth face cunt and hand you over to the boys.”
Sweetie squeaked and pulled her face away from the rolling pin, a string of thick drool still linking it to her lower lip. “Um, fucking red, you psychopath.”
Diamond sighed and rolled her eyes. “I wasn’t actually gonna do it. Silver! Get your face out of the slut’s ass and help me lube this up some more. Let’s make her crawl to mom and dad’s bedroom with it up her ass.”
✭☆✭☆✭☆✭
Sweet knelt face down ass up on Filthy and Spoiled’s bed, guts full of joy and rolling pin, watching video of her fat ass waggling through the air with a rolling pin handle sticking out the back. She trailed her finger across the screen, pulling the timeline back to see the footage Diamond had shot after retrieving the rolling pin. She watched the camera’s view wobble up the stairs, at first seeing only Silver’s long tail, then her sleek ass and long thighs, then her tits — easily visible around her narrow rib cage — jiggling as her face bobbed between Sweetie’s cheeks. Shaky pan around to see Silver’s glasses resting on Sweetie’s butt, and her middle finger waving at the camera.
“DT why do your parents have a double-ender?”
“Harmony, Silver, I don’t know.”
“DT does your dad have a pussy?”
“Probably.” Diamond flopped on the bed next to Sweetie, cradling an armload of her parents' sex toys against her big fake tits. She nuzzled Sweetie’s cheek, and Sweetie looked away from the phone to kiss her friend. The feeling of Diamond’s tongue darting around inside her mouth made her lips tingle. She looked to one side; there was a big mirror at the head of the bed and another one on the ceiling. Filthy and Spoiled must have a hell of a sex life.
“Are you sure we’re going to be able to get this thing out again?” said Silver, stroking Sweetie’s ass. Her fingers slid under her dock and stroked the rolling pin handle that was all that was sticking out of her ponut.
“Watch this,” said Sweetie. She bore down with all of her might, and slowly, ever so slowly, her powerful anal muscles squeezed the edge of the rolling pin out of her boy. “F-fuck,” she muttered, hips trembling with exquisite anal pleasure as she felt the massive object sliding out of her guts into the open air.
“Oh my Harmony that’s disgusting,” said Silver Spoon, covering her mouth.
“Oh, pony up, you wimp,” said Diamond. “I think it’s beautiful.” She stroked Sweetie’s ass. It was still glowing red from the beating at the bottom of the stairs, and the caress stung like a beesting.
“It’s getting a little uncomfortable, to be honest,” said Sweetie. “Can I get something softer back there? The double-ender would be nice. I’d love to go ass to ass with one of you.
“How about ass to mouth,” purred Diamond. Silver Spoon purred in agreement.
She ran her hands over Sweetie’s ass cheeks, then slid them under her tail and helped pull the rolling pin out of Sweetie’s plothole. Sweetie felt herself gaping again, so free and open she imagine she felt a breeze blowing clear through to her mouth. She felt something poking around in there and laughed. “I’m gonna be a little loose back there for a while. Why don’t you two play with it?”
In the mirror, she saw Diamond and Silver grin and start kissing each other around the sides of the double-ender. They licked it, and licked each other’s tongues, stroking it and sliding it in and out of her wide-gaping ass.
“See how deep it’ll go while she’s still open,” said Silver. Diamond nodded and pushed the dildo deeper and deeper into her. “It’s not hitting a limit.”
“Oh. That feels really weird,” said Sweetie. “You’re deep in there.”
“There are about nine inches sticking out, and you’re finally closed down around it,” said Diamond. “Silver, if you wanna gag on it?”
“Yeah, like I’d gag on nine inches.” Silver made eye contact with Sweetie in the mirror and slid effortlessly down the thick shaft until her nose was under Sweetie’s dock. She bobbed there for a while, then popped off, drooling. “Feels good. You wanna try?”
Diamond nodded. Silver pulled her hair aside so that Sweetie could have a good look, and Diamond popper her lips over the dildo. Silver pushed on the back of her head, and soon she was throat deep with her face mashed between Sweetie’s Ass cheeks.
“Mgmph!” moaned Diamond, and Sweetie pushed her ass against her face.
“I feel like I’m not challenging you two. Hold on.” She pressed down and slid the dildo out of her ass directly into Diamond’s throat. Diamond gagged, but Silver held her head in place. Tears rolled down Diamond’s purple cheeks, her snout stretched wide around the thick rubber dildo.
“F-fuck,” moaned Sweetie, rubbing at her pussy. “You okay, DT? Safeword out if you can’t handle this.”
Silver giggled. “She can’t safeword with her mouth full, can she?” Though of course, they had physical signals for when mouths were busy. Still, it was fun to pretend they had Diamond trapped. “You can’t see it from here, but she’s playing with herself. She’s loving this.”
Sweetie Belle moaned, arched her back and shoved her ass into Diamond’s face. She used both hands on her own pussy — one on her clit, the other hooking three fingers up her tiny cunt. “Harmony! Harmony! Gag her on it! Oh!”
Silver grinned and slammed Diamond’s face into Sweetie’s ass. Diamond made a hideous gagging noise, and her body convulsed. Her breasts slapped against the backs of Sweetie’s thighs.
“What happened? Is she okay?” gasped Sweetie Belle.
Diamond elbowed Silver away from her long enough to grab a breath. “No. Came. Hard.”
Sweetie’s lower belly burned with desire. “Gag her again. I’m almost there. Do it!”
Silver tangled her fingers in Diamond’s hair and shoved her face into Sweetie’s ass crack. Diamond’s shoulders worked hard, rubbing another thrashing orgasm out of her clit. Sweetie jammed her fingers down on her own clit and shoved fingers up into her cunt as deep as they’d go. Pleasure rushed through her body. Her thighs thrashed, knocking Diamond and Silver off the back of the bed.
“Ouf!” said Silver. “Harmony, be careful!”
“Ohhh, that was so fun,” moaned Sweetie, still rubbing at her aching pussy.
“I’m glad it was good for you,” said Diamond, crawling back up to the bed, her voice sounding like she’d been smoking three packs a day for ten years. “But be fucking careful next time.”
“It’s my turn now,” said Silver, standing up and rifling through Diamond’s parents' bedside table for lube. “I wanna go ass to ass with her.”
“Oh, yeah! That sounds great! Diamond, set us up.”
Silver lay face down on the bed, legs spread, and handed the tub of lube to Diamond. Sweetie leaned over and got a big scoop of lube, and helped rub it into Silver’s asshole. They spread goop all over the outside, then slid their fingers in, slowly stretching and pulling her until she was ready for the double-ender that still hung out of Sweetie’s ass. The dildo wasn’t as thick as the rolling pin, and so no trouble at all for an expert like Sweetie. For Silver, though, they needed to take care not to hurt her.
“Looking nice and open,” said Sweetie, sliding three fingers in and out of her friend’s ponut.
Diamond squeezed Silver’s small round ass, then gave it a smack. “Bend over, and we’ll get you two hooked up.”
They knelt crossways across the bed so that they could look sideways and see themselves kneeling butt cheek to butt cheek. Diamond pulled the double-ender a few more inches out of Sweetie’s ass, and rubbed the head against Silver’s ponut. Sweetie felt her tense and Diamond slid the dildo inside her. She rubbed it in and out, gradually pushing more and more in, and of course, this made the dildo move back and forth inside of Sweetie. She shivered, making the dildo wiggle in Silver’s ass.
“F-fuck, it feels so good,” said Silver.
Diamond slapped both of them on the ass. “All set. Off to the races.”
Sweetie pushed her ass back hard. She hit Silver’s hard, round little butt with a resounding slap, sending a jolt of pussy-warming pain through her battered cheeks. Silver yelped. The motion had jabbed the dildo into Sweetie’s guts, and she knew it felt exactly the same for Silver.
“Harmony, Harmony!” gasped Silver.
“Too rough for you?” said Diamond in a mocking tone, stroking both her friends’ asses and leering down at the dildo stretch between them.
“No. Harder.” Silver gritted her teeth, and arched her slim back, leaning into Sweetie’s soft ass.
Sweetie obliged, jamming her butt back against Silver’s tail waving high in the air, loving having her guts plowed by the dildo stuffed up her frenemy’s ass. They hit hard, again and again, furry flesh juggling, the sound of smacking and squelching filling the room. She looked over at the mirror, craning her neck to get a good look at Silver. Her face was on the bed, eyes wide, glasses askew, cheeks flushed, staring at her in the mirror. Sweetie especially liked the way Silver’s tits flattened out against the mattress; huge natural boobs pancaked by their own weight.
“Looking good, Silver,” she moaned, hooking her legs around her thighs and pulling her close. Their asses smacked together, the dildo barely visible between their cheeks.
“Gonna… gonna cum…” moaned Silver.
“Bullshit,” said Diamond. You’re not even touching yourself.
“Anal orgasm happens,” said Sweetie. “The ass’s capacity for pleasure is limitless!”
“Feel you… so deep inside me…” gasped Silver. “Harder. Harder!”
Diamond slapped Sweetie Belle’s ass. “You heard her, nerd. Ruin that slut.”
Sweetie licked her lips, got a good grip on the edge of the bedframe, hooked her legs around Silver’s, and laid into her. Naturally lower body strength and a daily habit of doing squats gave her ass and thighs phenomenal power, and she gave the thinner mare everything she had. The little gray ass trembled under the assault of Sweetie’s massive white one, flesh jiggling bones vibrating. The double dildo speared their insides, pounding deep, rubbing on all sorts of wonderful and mysterious nerves and loci of lustful pleasure. Sweetie felt her own body tensing for another orgasm, exhausted, brutalized flesh reveling in the abuse it was receiving. A little sun built between her legs, growing, hot and sweet and intense, filling her belly, swelling, ready to burst.
“Ahhh! Ab ah ah ha!” screamed Silver. Her glasses slid off her face entirely, her eyes rolled up, her tongue hung out. Her hips shook violently as pussy juice splashed out of her cunt and onto Diamond’s parents' bed.
“Sweet!” said Diamond, gripping her friends’ ass cheeks hard. “Sweetie! Your turn!”
The sun between Sweetie’s legs went supernova. She felt it knock her forward, off the bed and into infinite, star-filledl space. A warm and loving light enfolded her.
“Greetings, my child,” said the Voice of Harmony. “You have traveled far to… What? You again?”
Sweetie had the sensation of her soul being swatted violently back into her body. She lay on the bed in a tangle of legs, dripping with sweat and drool and mare goo. She felt Silver, still tied to her ass, panting like a dog.
“You okay, nerd?” said Diamond, grinning and stoking Sweetie’s mane. “It looked like you blacked out again.”
Sweetie gave a shaky thumbs up. “I’m great.” She looked up at the big fake purple tits swaying over her head. Damn those were gorgeous. They needed sucking. “Still kind’a horny, though. What say we give my ass a soak in your parents’ hot tub and then go again?”
