"Hey...did you hear? Something happened to one of the euclids..."
"This is coming from a class-D but apparently...item three-two-"
>There they go again...starting up more bullshit rumors.
>For all the strict confidentiality O5 loved, they didn't give a damn about the rumor mill.
>Or maybe it was just the administrator who didn't care to report it.
>Either way, every morning at the canteen had the same hushed whispers.
>Whatever, it was bound to be bullshit.
>Blocking out the hushed and hurried tones, you focused on the papers you had in hand as you had some cereal...
>'ORDERS FOR CLASS-C PERSONNEL: C-1352 // You are to report to containment site BPD.'
>'Upon arrival at the site, C-1352 is hereby required to perform routine maintenance on chamber E-956.'
>'Threat level: Low - Expected level of response to personnel: None'
>Fun. At least it was a step up from the fucking peanut. And you didn't have to worry about a drowsy class-D fucking it all up.
"Yeah, get this...apparently it started talking to him..."

/ / / / /

>God. Why did you have to let that last whisper get by...
>You were in chamber E-956, a small little cement block really. Standing atop a ladder as you fiddled with some wiring.
>But every few seconds you felt compelled to glance over your shoulder, to check on your little...'companion'.
>All because of that stupid fucking rumor.
>Unsurprisingly, chamber E-956 had item-956. Administration didn't like you calling them SCP, said you had a nasty tone.
>Regardless, that fucking pinata was spooking the shit out of you.
>You knew the thing fucking walked around sometimes, pacing the walls, pointed one direction. Creepy little fuck.
>For all the bright and fun pastel colors, the rainbow horn, the soft pink fur, it just made it all the more unnerving.
>"Mnh. Fuck it."
>Trying to keep your mind off the rumor, you turned back to the camera, let the guard worry over the pinata.
>You could tell the guard was getting antsy too, he probably hadn't been in the room this long.
>For whatever reason 'Radical fuckin' Larry' had decided to really fuck up the camera wiring today.
>You swear that one had it out for you. Or maybe wanted to keep you busy.
>Every other week he broke out and just ran havoc, destroying everything he could get his grubby little hands on.
>It'd be funny if it also didn't mean everything else had a chance of breaking loose.
>Heavily corroded wiring fell to the floor as you trimmed it away, containment would just have to bear with some rewiring until new cameras came in.
>It wasn't the best solution, but it worked.
"H-hey, C-1...2? Uh, C-class. I g-gotta duck out for a second. You okay in here?"
>Oh boy, time to break protocol.
>"Yeah, I'm good. Pretty sure I'm not in this item's strike range anyways."
"Th-thanks!"
>Just how spooked was this guy? Either way, he still backed out of the room, eye trained on the fluffy little toy before closing the door behind him an-CLICK!
>And locked you in here with the item...cool.
>Imagine a world where people didn't constantly try to screw you. Good thing the fluffy little horse friend of yours dormant for now.
"Phew~, finally alone hot stuff~..."
>Your hands froze in the middle of stripping some wiring. You were the only one in here right?
>Glancing over your shoulder, you saw the item, still propped up against a wall. Utterly inanimate.
>...Fuck. Auditory hallucination. Time for more amnesiacs.
>Turning back to your work, you reached for the extra copp-
"Whassa' matter? Take a look at a pretty lil' thing and you need to turn away~?"
>What.
>Your grip on the wire stripper tightened as you looked over your shoulder once more. It had fucking moved. It still was moving.
>The fluffy pinata had its suddenly lidded eyes trained on you, the creature had moved away from the corner and was now seated a few feet behind you.
>What the fuck.
>Slowly, you fully turned to face the active item, hand still tight on your tool. Your heart practically pounding out your eardrums.
"Mmh~, you look even better from the front, big guy~..." 
>Its eyes fluttered almost as it lounged upon the floor, gazing at you. One hoof propped up to support its head. Seriously, what the fuck.
>"You...what are you doing?"
"I'm just tryin' to get to know my visitor a bit~. Is there anything wrong with that~?"
>Why...why was it fucking flirting with you. How did it even know how to flirt?!
>Ok no, this was bad. Normally the pinata was just mindlessly aggressive. It was talking now. It was fully sapient. You had to get out of here right now, you ha-fuck the door was locked.
>"Look. Whatever you're doing it's not going to work. The guard will be back in a few moments. And I'll be long gone."
>Maybe if you just tried to keep it talking, keep it distracted from trying to murder you, maybe you could get out of here.
>But your words weren't having the effect you'd like them to have. The fluffy pinata growing a wide grin as it continued to gaze at you, eyes still heavily lidded as its brow raised.
"You sure about that, hun~?"
>Just as it spoke, a tremor ran through your body. And it didn't come from you. The entire facility was shaking.
>A klaxon went off, the lights dimming and flickering as the walls shook.
'ALERT. WE HAVE A CONTAINMENT BREACH IN SITE BPD. WE ASK THAT ALL PERSONNEL REMAIN WHERE THEY ARE AS THE ITEM IS PROCU--ATTENTION. ITEM 323 IS CURRENTLY ENTERING THE HALLWAYS. ITEM 096 SEEMS TO BE IN PURSUIT AS WELL. REMAIN AT YOUR STATIONS. REMAIN CA--'
>You could feel all the blood draining from your face as the feed was cut short. Fuck. That class-D was right.
"Aww, don't look so scared, honey~. I'm here to keep ya company, huhu~."
>Slowly, the pinata rose from the ground, its eyes still absolutely brimming with an emotion you admittedly did not want to prescribe to a children's toy. But that didn't change the fact that need was practically oozing from the toy.
>"Look. Stay the fuck away or I'll start swinging!"
>Holding one hand out, you raise the stripper. But all that happens is the small horse-thing giggles. Admittedly...kinda cutely.
"Heheheh~, you silly~. I remember you. And I know what that means. That you've been here before, that they've told you...warned you, all about lil' ol me~! Now stop being a silly billy and drop that toy of yours~..."
>Shit. Fuck. Piss. F U C K.
>Your hand squeezed around the handle of the tool, but that thing was right. No amount of blunt force would be putting it down. All you'd end up with was a sore wrist.
"Oh, that's a good look~..."
>Apparently your frustration was showing through your face, quickly you tried to give a stern look as the pinata brushed your hand aside and walked closer to you.
>Fuck. Now your hand tingled. You knew what this thing was, but when your hand had brushed against its fur, you could feel how soft, how luxurious it was...
>You felt powerless, and just let the item draw closer and closer, until its hooves were on the stool with you and-
"Boop~!"
>Its muzzle pressed against your crotch.
>You could feel your cheeks begin to brighten as the pinata continued to nuzzle against your pelvis, its soft white snout trying to bury itself into the split of your jeans.
>It was feeling kinda...good.
>Slowly, your breathing had begun to quicken as the item continued to rub itself against your lower body, both of your hands pressing against the wall for support as the creature sniffed at your growing bulge.
"Ahh~, so masculine~..."
>Please. You did not want to hear that. But regardless the pinata started let out small moans, before raising its snout and biting down upon the lip of your jeans. In a swift tug, the button of your pants was almost torn off as your fly was popped loose. The pinata wasting no time in securing your zipper between its lips.
>Zzzzzzpp...
"Fuck yesss~..."
>A shudder ran through the item as it began to grind its nose against your increasingly erect length. Your cheeks were burning now, you didn't want to admit it, but it was beginning to feel really good. The unicorn creature's fluffy snout ground against your briefs, huffing your crotch, and pressing harder against your waist.
>Too hard.
>The stool beneath you slid away, your balance lost as you tumbled and hit the hard cement floor. The stripper clattered out of your hand as you felt your head bounced against the wall, vision darkening for a moment.
>"Mngh! F-fuck!" You were on the floor, eyes clenched as you felt your brain slosh around inside your skull.
>Slowly, you opened your eyes, blinking and re-adjusting to the light-
>"Mnh!" Your lids snapped wide open as instead of the ceiling, you saw a familiar fluffy face looking down at you. Of course, the pinata hadn't been injured from the short tumble.
"Ah, you look even lovelier from here~!"
>Jesus. Were its eyes actual hearts right now? 
>Wait, why was the floor so co-glancing down you see your bare thighs, and bare crotch. Apparently, you had actually managed to been knocked cold for a moment. Long enough for your briefs to have been tugged back, leaving your rear on hard, cold cement.
>But that wasn't the only...unpleasantness you saw. Your heart practically stopped beating when you noticed it. The long tube hanging from between the pinata's legs. The very, very concerning tube with twin spheres hanging behind it. The tube covered in veins with a flared tip that was currently bouncing against the pinata's belly.
>Over 12 inches of flesh jut from the pinata's crotch, vibrant layers of color stretching across the shaft, leading up to an obscenely gravid package, coated in that soft, comforting fur.
>And as the item's length bobbed up and down, you saw it growing fatter, longer... The pinata was hardly even 2 feet tall, but you were soon looking down a shaft over that length, thick as your wrist, its fat, plump urethral lips staring you down.
>Even the item's package had grown fatter, the orbs inside having thickened from your gaze being upon them, furry sack becoming taut as the item's testicles swelled to well over the size of your fists.
>It was obscene, disgusting, and aimed towards your rear.
>Flicking your eyes back up, you were only greeted by that near manic gaze, the creatures normally dead black eyes replaced by almost throbbing hearts as it gazed down at you, nostrils flaring as it panted in need.
>"L-look you d-don't need to do this! I-I-Mnh!!?" You're cut off mid-sentence, your attempt to talk your way out of this failing spectacularly as the unicorn toy slams its lips against yours, suddenly pulling you into a kiss.
>And what a kiss it is. The item's saliva drips into your mouth, sickeningly sweet as it mixes with yours, and then its tongue joins in as well. Your own tongue is quickly wrestled by the creature's, pushed down into submission so it can claim more of your maw.
>Against your better judgment, against your will, you feel her cheeks blazing in warmth, and you let out a moan.
>"Mmmnnnhh~..."
>This only encourages the pinata as it ravages your mouth, slick, wet sounds filling the air as you're forced to make out with the item, forced to accept its ministrations.
>And fuck...it really feels good. Your mouth is practically buzzing in delight as the sugar-laced drool of the pinata pours down into you, you don't want this but...it just feels so good...
>Caught in the pinata's hold, increasingly pliant in its grip, everything seems to revolve around what's going on in your maw, yourself unaware of the creature changing position, sliding your legs atop its haunches...
>Before you can notice it, your legs are bent above the unicorn's, and it thrusts forwards.
>"Mngh-!?"
"Mmmh~!"
>The item moans into your lips, refusing to break the kiss as its wide glans presses against your asshole.
>Slowly, the pressing becomes stronger, more insistent, more intense. And slowly you can feel your anus beginning to give up.
'Shlph~!'
>And then its inside. Your asshole now the home to one horrid entity's throbbing shaft, your anus throbbing around the sheer width of the unicorn's cock.
>You had never even thought about anal, and now your asshole was being spread around a horsecock belonging to a small children's toy. Shaft forced inside without any lube.
>Saying it hurt was an understatement. It fucking throbbed like hell, your anal ring quivering as pain ran through your nervous system. The only thing helping you hold back your growing urge to scream was the broad tongue still swabbing about the inside of your mouth.
>But as abrupt as the entry had been, it was only the entry. As you writhed on the floor in agony as being de-virgined by a gigantic horsecock, the one violating you kept still, content to just have their iron-hard glans embedded inside you.
>Lying there on the floor, horse creature looming over you, horse creature fucking embedded within your asshole, the pain slowly began to ebb away. Your once virgin anus becoming used to the massive cock now splitting it open. 
>Ok maybe used to was too strong of a statement. But the pain was becoming bearable, your throbbing anal ring slowly learning how to accommodate that massive fuckstick.
>The tears that had formed in your eyes began to disappear, drying away as you felt the pain radiating from your asshole begin to disappear. Instead...it felt...kinda good?
>Just as that thought occurred, the pinata lifted its lips from yours, allowing you to breathe through your mouth once more, a strand of drool still connecting your lips to its.
>Why was your heart...pounding so much?
"You're so tight~... I'm gonna go a lil' deeper, okay hun~?"
>The creature's words hardly registered, but swallowing the sugary drool still in your mouth, you slowly nodded your head.
>Given the signal to go forward, the pinata leaned its hips downwards, and slowly your asshole was filled with more of its horsecock.
>"Mngh~!" Your tender ass sparked in discontent, but your eyes filled with colors, arousal coursing from your violated asshole and shooting up your spine.
>It was impossible not to shiver as your brain was suddenly bombarded by the pleasure flowing from your rear as the item sunk her cock deeper into your rectum.
"Oouuh~, tha's good~... K-keep it up, hun~!"
>The tool inside of you throbbed and sputtered, oozing out pre, lacing your inner walls with the sugary lubricant, the unicorn's hips beginning to descend at a faster rate.
>Your own tool throbbed and jerked at every inch sheathed within you, another bit of your body being explored by the amorous pinata's horse-like length. Nerves lining your anus flared to life, more of your pain being smothered by growing ecstasy, growing delight, as the massive tool hanging from the toy's crotch was sunk inside of you.
>All you could do was clench your hands shut and relax, panting as you felt your anus become increasingly filled with horsecock, the shaft inside of you beginning to widen as you neared its base.
'Shlp~!'
>Suddenly, an added inch of width plopped inside of your tenderized asshole, and your entire body quaked. Muscles clenched and squirmed as the unicorn's medial ring sunk into you, your warm hole squirming and writhing about the unicorn's shaft in response.
"Mnnnhhff~! Y-you know how to treat a girl r-right~!"
>You can't speak, it's impossible. Your cheeks glow in pride at the item's praise, but it feels like your lungs are being split apart by the tool slithering deeper into you, leaving you slick with sweat and panting as your anus greedily accepts more and more cock.
>Just when you think its too much, just when it feels like your entire body will tear apart, something slaps against your rear. Two somethings. Two fat, furry, warm orbs.
>Every inch of the pinata's cock was now inside of you, throbbing and squirting pre as your hole clenched around it.
>You could feel it, your belly bulging slightly in the shape of the girth now resting inside of you, every pulse of the pinata's cock echoing on the surface of your waist. You had never felt this warm, this full before.
>Every second spent like this, you could feel that massive length throbbing inside of you, grinding up against your prostate, and making your own tool ooze out pre.
>Your face was glowing, blazing in warmth, and your eyes met with the unicorn's. Its face had grown red as well...redder. This time, you rose to meet its lips, your tongue entering the items maw as your legs curled around its haunches.
>Giving the creature the go-ahead it had been craving.
>Breaking away from the kiss, it looks at you with lust-filled eyes, passion practically radiating off of it. The heart-shaped pupils in its eyes almost throbbing in desire.
"Heere...weee...gooo~!!"
'Schluck~!'
>The massive length filling your body is jerked backwards, filling the air with a slick sound as you're emptied of horsecock.
>Over a foot of the item's length is back outside of your rear end, leaving your hole quaking and shivering, and then its jammed back inside.
'Schlk~!'
'Fwaph~!'
>Every single inch is plowed back into your anus, your prostate squashed under what felt like a metric ton of equine shaft. Your own length jumps as a spurt of pre arcs out from your tip in response.
>And to top it all off, that fat unicorn ballsack spanked your rear, causing your hole to reflexively tighten around the pinata's shaft.
>Your eyes almost roll up into your head, pleasure arcing through your mind, how did this feel so good? Why had you never done this before?... Was this gay?
>Before you could begin to answer that last question, the pinata's hips jerked backwards once more, the bulge of pony cock in your belly disappearing, your anus being yanked free of massive, throbbing cock.
'Shlurph~!'
'Schlk~!'
>And then was thoroughly fed every inch once more.
>Again and again, the pinata thrust its hips back and forth, its fat length sliding in and out of your asshole, leaving you quivering underneath it.
>Your mind was aglow with pleasure, sweet bliss as your anus writhed and suckled on the length slamming in and out, desperately holding onto it.
>Arms and legs wrapped around the pinata, you held it in place as it bred your rear, your stomach bouncing up and down in the shape of its girth, its fat ballsack slapping against your rear, filling the air with loud thwacks of flesh on flesh.
"Y-you're, s-so tight~!"
>"F-fuck-fuuuck~!!"
>You could feel its length swelling inside of you, medial ring dragging back and forth along your insides, flared glans scraping against your inner walls.
>This fucking toy was dominating you, and it felt good.
>The unicorn's hips became a blur as it pounded you full of pony cock, your asshole becoming stretched out in the shape of its massive girth, ruined by the creature's shaft.
>And all that did was make you hornier, hornier that you were allowing this fucked-up living toy to breed you like some whore.
"Ah-ah'm g-gettin' close~!"
>The shaft filling out your innards began to swell, your tenderized flesh being forced to new limits as the pinata neared its climax.
>Your poor prostate was already squashed and was now being squeezed into nothingness, pre squirting frantically from your length.
>Tightening your grip on the pinata's neck, you pulled it back down into a kiss, smashing your lips against its as it dominated your asshole.
>The massive heart-shaped pupils bulged in size as its eyes popped wide in surprise, but then it returned the kiss, tongue entangling with your own as its hips began to slam with greater force against your rear.
>One...two...three...four...five!
>Mentally, you counted out its final thrusts as your body shook, trembling under the sheer force of every thrust, until you were once more pumped full of the entire length, the already obscenely-large cock swelling larger as it began to orgasm.
'Ghlurph~! Ghlurk~! Ghlnk~!'
>The room echoed with the sound of the pinata's orgasm, its fat balls scorching with heat as they rubbed against your rear end. Every trembled of its cock echoed through your body as you were pumped full of unicorn-jism. 
>A core of heat building up inside of you as the pinata filled you with dense packets of sperm.
>Slowly, your belly grew, endless pulse after pulse of pony nut-sludge building up inside your belly, bloating it.
>But your mind was elsewhere entirely as the weight inside of you, the growing warmth of your insides as you were packed full of equine jizz triggered your own orgasm.
>Your hole suckled and clenched around the swollen shaft as your tool throbbed and bounced, your own payload firing off between your increasingly gravid belly and the pinata's soft fur.
>Mindlessly, your lips met with the pinata's, tongues entwirled as your mind went blank in sheer ecstasy. Cock shuddering and dumping out the largest climax you had ever had.
>However, as your climax tapered off, the item's continued. The pinata's sheath bunching up as it was ground against your asshole, jabbing an extra inch of length inside of you.
'Ghlurph~! Ghluhp~! Gluck~!'
>Every load was as thick and heavy as the first, pumping you further and further full of the item's DNA. And all you could do was quiver in ecstasy as you were bloated like a balloon, belly full of nothing but the pinata's sperm.
>Maybe minutes later or maybe hours, it was hard to tell, the constant pumping of pony sperm into your asshole began to slow, until the last few drops of jism squirted out into your hole.
>You were a bloated mess. It looked like you had been packed full of another pinata, maybe one and a half. And slowly, the one mating your hold ground its hips back and forth, causing your insides to quiver in pleasure.
>And then you noticed, the item's cock was still rock hard.

/ / / / /

"C-1352? Are you in here!?"
"H-he was i-in the cage when I left and locked...the...door... Oh God."
>The chief of security shot a death glare at the officer. It was one thing to leave personnel unattended during a containment breach. But to lock one up with a specimen?
>The officer would be paying for this mistake for more than a few months.
>Regardless, the chief kicked open the door to the room, weapon trained as he scanned it.
"I repeat. Personnel C-135...-what in the world?..."
>You were on your knees, face blush, panting in pleasure as the pinata rode you, massive cock slamming in and out of your well-used hole.
>It had been at it for hours, the floor slick with the jism that had escaped your asshole as you were thoroughly trained to accept its cock.
>Your stomach bulged obscenely, an inhuman amount of jism packed away inside. Numerous pony orgasms had been dumped inside of you, your body a sperm-tank for the pinata.
>In fact, you didn't even see the chief staring down at you, all you could feel or care about was the pinata's wonderful cock, slamming in and outside of your asshole. Now and forever...
