Author's Notes:

This was a fun commission to write, follow-up chapters are planned.

William watched quietly as the automated delivery robot entered his living room, placed the large, surreptitious package on the floor, then went back to the door. He thanked it profusely with gestures it didn't even slightly understand, then closed the door behind it. The rattle and clicking of three deadbolts being slid into place filled the empty air.

With that taken care of, William walked back to the waist-high box, squatted down in front of it and tried to slow down his pounding heart.

Ponies.

Real ponies. There was no longer the barrier between 2D and 3D separating him from them, they weren't trapped on the other side of the viewscreen projector any more.

The invention of the bio-droids sometime around the turn of the century had catapulted mankind into a golden era. Heralded as an entirely new, yet programmable form of life, bio-droids were cheap, efficient artificial beings that could perform all the jobs that humanity as a species felt they had outgrown. Hazardous mining, heavy construction, it was all risk-free for a species that didn't get tired, could be repaired or have core components replaced in seconds, and could download and upload their consciousnesses into any number of clone bodies as necessary. In short, it created a society where the concept of a "workforce" was now outdated. Every person contributed as much or as little to the larger populace as they felt was necessary.

While some people took advantage of the situation to stay at home and play with their new bio-droid sextoys all day, William Keller had a successful career as an investment and commodities broker that he was in no hurry to give up. He enjoyed the light work and it kept his brain stimulated. Besides, he'd never had any need for those sorts of toys!

Still...

He continued to stare at the box. During transport, it had been jostled enough that a purple horn was now poking out of the top, twitching periodically. Somehow that didn't help his racing heart one bit.

He picked up a pair of scissors and slowly began to chew through one of the wire cables keeping the box tightly bound. Upon doing the same on the other side, the lid flew open and not one, but two, quadruped resident of Equestria burst out of the box before his eyes! Of course he recognized them immediately: Rainbow Dash the pegasus and Twilight Sparkle the alicorn!

Rainbow caught his attention first, just like she'd always done back in his favourite cartoon, with bright-blue glowing fur, a mane and tail every colour of the light spectrum and that slender, elongated frame of hers. She gripped the edge of the box tightly, a playful grin on her face as she looked up at him. She even gave him one of her trademark smirks, as if to say, "Uhuh, I know exactly what you chose me for!"

While Rainbow bounced excitedly in the box like a newborn puppy, Twilight was studying him, cool and calculated as he knew she would be. The pony's eyes were half-lidded with a mix of suspicion and concern, and it was immediately obvious she wouldn't leap into his arms quick as readily as her companion. However, the warm glow in her eyes made him realize there was no hostility behind it: rather, her concern was born from only reasonable doubts. Even as a possession to be purchased by an owner, she was a free-thinking droid and a being who wanted to choose her own future.

The pudgy pony with the thick hindquarters and the round cheeks seemed about ready to say something, when Rainbow suddenly leapt into what was very obviously a premeditated speech! "Hi guy! Thanks for purchasing two of the raddest bio-droids on the market, you've totally made an excellent purchase today! We're both top-of-the-line C.L.O.P.P.E.R. units, so you know you're getting your money's worth! We're here to mindlessly obey any of your orders, follow any instruction, do anything we're told, so you just say the word and we'll do it! We're your sextoys from now on!"

As Rainbow talked, a look of horror spread across Twilight's soft features. She turned and nudged the other pony in the ribs. "Rainbow! Not only is that company spiel drivel completely out of date following recent legislation, but you managed to completely mess it up as well! Just let me do the talking, alright?"

"But we ARE droids, Twilight..."

"That may well be, but I'm still a perfectly free-thinking individual."

Twilight smiled up at William. "This man who's purchased us has entered into a contract with us, one based on kindness and respect. You wouldn't want to serve a nasty master, now would you?"

"Well, I guess not..."

"And all that stuff about us being just robots is implicitly untrue, we're able to think and feel. We meet all the requirements for life and our minds are capable of learning and developing just as much as humans are. I might be one of many bio-droids based upon the Twilight Sparkle pony, but once fabrication of my mind and body are complete, I will go on to extensively differ from the other models created."

"Yeah, I bet none of them are as mouthy as you are..."

Twilight laughed, a gentle, tinkling sound. "I assure you, the "real" Twilight Sparkle would respond exactly the same way in my situation. I spent my nurturing time in the bio-droid construction facility voluntarily studying the processes behind our construction and learning as much as I could on the topic. How did you spend your developmental time, Rainbow?"

"Well, I thought our master might be into kinky stuff, so I..." She glanced at William, then leaned down to Twilight's side and whispered quietly into the other pony's ear. Even with purple fur, he could just barely make out the blush spreading across Twilight's face.

"Well, uhh, I don't know about all THAT," said Twilight slowly. "Actually, I know it's our primary function to serve and all, but I do intend to also set aside some personal time for studying and broaden - Hrrrk!"

While she'd been speaking, Rainbow had slowly been extending one of those enormous wings up and behind Twilight. With a little twitch of her upper back muscles, she reached the feathered tip behind Twilight's ear and flipped a small switch hidden away under her hairs. The purple pony visibly stiffened from mane to tail, her pupils dilating, her tongue extending out of her mouth. A realistic sweat-substitute beaded all along her body as her sex-organs became flushed and reddened. "Hhhhff... Oh Celestia, I need... Haaahhh... I need a..."

Rainbow grinned in William's direction, flipping her forelocks. "In-Heat switch is behind the right ear. You'll find it in the instruction manual under page 32. You can thank me later, bud." She flipped the switch again.

Twilight sucked in a big gulp of air as if she'd just been underwater, then glared sideways at Rainbow Dash. "That wasn't very nice, Rainbow. Well, anyway, can you please let us out of this box? We'd like to complete our user registration and synchronize with our new surroundings."

"Oh, uh, sure thing," he said, quickly freeing them from the box. He helped Twilight out first, the pony large enough to come up to his waist, then hefted the significantly lighter Rainbow out as well. While Twilight was heavy enough he had to grunt and strain with the Alicorn's body, he felt like he could've tossed Rainbow in the air and caught her effortlessly!

"Now, a few details... First, your name?" asked Twilight.

"Uhhh... William Keller."

"Age? Home address? Occupation?"

He answered the questions one by one while Rainbow waited impatiently. Eventually Twilight said, "Umm... Orientation?"

Rainbow Dash took the opportunity to leap onto his back at that point, closing her marshmallow hooves around his neck. "Ponysexual! Like, duh!"

She felt warm and soft back there, and his heart melted a little more. He reached behind himself as he answered the rest of Twilight's little Q and A session. He found Rainbow's mane and she eagerly leaned into him, receiving a good, long petting.

Once she was finally done, William realized it was already getting late, and stifled a yawn in front of the two ponies.

"Well, ah, we should continue this later, I'm getting tired."

He scritched both of them behind the ear gently, then turned to go towards the bathroom. As he brushed his teeth, he tried to focus on calming down a bit, not to mention stifling the beginnings of a stiffy that threatened to be the motherload of all erections if it were allowed to reach full mast. It felt like, if he allowed that boner to take over, he might never get control back. He gulped nervously as he pulled on his pyjamas and climbed into bed.

He'd barely been lying there for a few minutes when he heard the bedroom door creaking open, followed by a pair of little heads peeking through the crack. Their large, cartoony eyes met, then they both cracked naughty grins as they sidled into the room. A pair of bumps appeared under the sheets, which began rapidly moving towards him, the sound of girlish giggling filling the air.

Rainbow popped up on his right side, resting her head on his chest. A moment later, Twilight did the same on his other side, circling a hoof on his stomach. "Hey now, mister, you weren't really gonna just drop out on us, were you...?" asked Rainbow.

"That would be highly inconsiderate as our new owner, I agree!"

"We're just like regular girls, sport, we got needs."

"Ahh... Well, not "needs" per se, but certainly feminine desires..."

"Twilight really needs her tail-pipe stuffed."

"Rainbow! I desire to have my tail-pipe stuffed, it is quite different. Now, master, take your hands and place them on our behinds, would you?"

He looked blankly from one smiling face to the other. "Right now?"

"Your hormone readings indicate you're not tired one bit. My analysis would indicate you're simply experiencing some initial shyness that will abate considerably once your tension has eased a little bit."

Rainbow's eyes shone with greed at that comment. "I dunno about all that, but if Twilight says you need to let out some hot, sticky "tension" out, I can totally agree!"

Under Twilight’s instruction, he placed both his hands on their thick rears, fingers sinking into the soft flesh. He grazed against a receptive pair of holes that sucked eagerly at his fingers. “Mmmn. It feels so real,” he huffed, and Twilight just nodded coolly.

“It feels real because it is, sir. Bio-droids are composed of organically-grown materials indistinguishable from human flesh, produced from the bodies of other bio-droids using similar processes to how “natural” species have their children.”

“Twiiiiiiiii! How am I supposed to help this dude get his bone on when you’re droppin’ all this science stuff all the time?

“Oh really? Maybe I’d better let you take over from here on, then?” said Twilight with a smile. “But perhaps I could actually suggest a more appropriate use for both our mouths at this point in time?”

Rainbow Dash nodded, her snout turning to an easy grin. “Now you’re talking!” Both pony’s heads disappeared back under the sheets and William could only wait anxiously as they got to work.

His pants came down all the way, letting that long, large cock flop out freely. What an amazing specimen it was! They were barely able to contain themselves, the fluids dripping down their inner thighs a testament of their arousal.

It was already standing at full turgidity, like it could smell pony pussy in the room. Their juices flowed even more freely, responding like the animals they were. Four forelegs were gripping his lightly-haired thighs as their mouths hung over that twitching, sticky-tipped pole.

They wanted it in their mouth. Right now.

As always when bio-droids cooperated to suck a guy off, they didn't needed words to communicate, they'd just understand each other perfectly. After a few moments of nuzzling his shaft, Twilight was the first one sliding her lips down his shaft, bobbing her head eagerly on his cock.

William relaxed slightly as they got to work. While Rainbow sat back and watched, Twilight continued her work, and it didn't take long for her to leave his rock-hard pole glistening wetly with her saliva.

Rainbow Dash quickly took her turn as soon as she was allowed to. In a swift motion, she shoved all of his cock down her throat. For once it wasn't just that she was trying to show off, she merely wanted to know how it felt to have such a ridiculously fat cock up her throat. It was tight, as expected. She wanted to do it again almost right away! Mister Keller's rear actually lifted up off his comfy bed for a moment, the male huffing and letting out a sudden cry from the intense pleasure Rainbow Dash was subjecting him to... The feeling of his dick being made to wallow in her naughty throat, surrounded on all sides by the flesh of a pegasus, had him ready to let his semen out almost right away.

"Mmm... Mmm, Rainbow Dash..." he huffed, suddenly placing his hands on her head. He began energetically thrusting into her face, hilting his fat dick inside her throat over and over again, luxuriating in the feeling of her throat. He used her mouth like a pussy, savouring the way it rippled around him from the base to the tip.

Twilight gasped when he began to move on his own inside Rainbow Dash's throat. As bio-droids they were used to the idea of servicing lazy men who expected them to do all the work, so to provoke such a physical reaction... It excited them!

She slowly pulled him out, letting her entire mouth squeeze his extra-thick member until the tip exited her gullet. Leaning on the side, she pushed herself down, shoving his cock head up her inner cheek, moaning in the process. She used her hoof to rub his tip all over the inside of her warm mouth

But it wasn't long before he wanted to try Twilight again. Once he finally pulled off her throat, slipping his penis free of Rainbow Dash's mouth, her petite body shook with a powerful orgasm.

It wasn't long before he was luring the purple pony back in. His penis went deep into her mouth. He drove himself into her, Rainbow watching as the Alicorn swallowed his cock. "Nngh... That's good, that's good..."

Their master was soon cumming! The sticky, hot smell of a man about to ejaculate was building up in the room, putting both the girls on edge. They experienced the same itchy sensation between their thighs, up their noses and, most of all, on their brains. The pleasure-centres of their minds were imprinting and recognizing this virile male who produced a lot of sperm as their owner.

He hilted inside Rainbow Dash again, cock erupting inside of her. At first he poured it down her throat, but then he changed the angle and hosed her tongue down with a large amount of his load. Still cumming, he drew his rod out of her mouth and moved towards Twilight. His cock throbbed before her eyes, mid-ejaculation, the strong pole growing bright red from contact with their bodies, his nutsack hunched up against his shaft as it forced semen up his pole, and the head a bruise-coloured purple. It twitched and volleyed a mesmerizing spray of semen across the room.

He pressed Twilight's lips and held it inside her, everyone able to hear the noisy glugging sounds of him filling her mouth, her cheeks bulging with the load of his cock. Their gazes were locked as he fed her semen. Both girls swallowed, slurping up the excess spunk. What had dripped onto the sheets was swiftly licked up.

Rainbow took a moment to steady herself, before a single beat of her broad wings saw the bedsheets thrown off of her, dramatically tossed into the air. She paused to smirk in his direction, knowing he was loving the show, then flopped onto the bed on her back with a loud sigh. She spread her hindlegs, drawing attention to her tight, throbbing butthole. It was plenty juicy, more than ready for a large cock to barge its way in. "Mmm, not a bad start! I think we both need a little more though!"

She punched a hoof into the flesh around her butt and teased her rump aside, flashing him her saucy goods. "Rainbow's waiting for you to get inside of her, stud! Don't you wanna try doing the fastest pony in Equestria back here, too~?"

Rainbow shifted on the bed, leaning towards him. One hoof rubbed up and down his shaft, while the the other cupped his large ballsack. Wherever the large, flat bases of her legs grazed that cock, they felt sticky and wet, instantly in need of a drying! Or licking clean with lashes of her little red tongue, either was probably fine! She jabbed her nose directly into his pole, face reddening and tongue lolling as she snorted its fantastic aroma.

She jabbed her hooves into the sides of the helmet and peeled his urethra, inserting her tongue inside. "This is the spot where your spunk comes out of, right stud? I've never played around with one until now!"

Her eyes were shining, darting from his face to his penis, back and forth. "I wanna learn all about this human dick of yours."

"So let's get started!" she said in a playful voice, lower body glistening for him. With him still sitting on the bed, little Rainbow got to work. Her hooves clasped his shoulders as she climbed on.

His eyes were drawn down to that forbidden spot between her slender thighs, where her puffy little love-nest was beckoning him. Just a glance at its large size could tell him she'd be able to stretch significantly to take him in, as if her little ass had been intended to fuck humans all along. She planted a hindleg on either side of him and doubled over, stroking his shaft, aiming it directly at her little butt! Her mane was so long it tickled the head of his penis when she shook it out. "Fucking~ Fucking~ I didn't know I'd be trying out a dick when I woke up this morning, mmm! I would've gotten out of bed a little easier, I bet!"

She looked up at him, that shit-eating grin back on her face. "You sure are a pervert, wanting to fuck pony-ass, aren't you? You'd have to be really lewd to get that big thing near me, knowing I might wanna try it out with my butthole! And making my mouth taste like your jizz! Even lewder!"

The huge head of his penis began to open her up, drawing gasps of pleasure and surprise from the pony. She raised her hoof to her mouth, eyes wide, as she stared down at it, the contrast between his pink flesh and her blue pony butt almost too much for her. "Wow! That looks really good, doesn't it? I wonder if anyone could ever imagine a guy wanting to fuck a cartoon pony like me... Probably they'd never even think about it, let alone do it like you are~"

She rocked her hips, pinning her labia to her thighs and smooshing them there. Space was at a premium between her thighs right now, but with one savage thrust, she finally crammed him inside her tight, hot anus. Other ponies might've cried out at the pain or embarrassment, but Rainbow was acting like she was possessed by a sex-devil! All she did was let out a naughty cry of "Take this!" and ruthlessly attacked his penis with her rear!

Her eyes rolled back, her whole face upgrading to a new level of lewd: hot clouds of sticky air emerged from her reddened mouth, her eyes widened all the way, and her pupils blossomed with love, puffing up from her normal shape and size to full-blown, anime-style hearts that shone with love for him. A blink and they were gone, but that had been no trick of his imagination. A true bonding of deepest, most heartfelt love was occurring here.

"Haaaaa... Mmn... Even if you're a real weirdo, you're really good at one thing..."

She rocked her hips in a tight circle, glancing the head of his penis from every side with her sticky, sizzling walls. His penis throbbed with each slap of her cock-trap. "Your impossibly good cock has really done a number on my lower half!"

William was sitting on the bed with Rainbow in his lap, facing towards him. She shifted her front legs behind her, bracing them on his thighs, and those big, beautiful hind-hooves rose up before his face! She wiggled them teasingly in front of the man, before suddenly planting them on his face, giving him something to lick and suck. Real pony hooves! Just like he’d imagined, they were incredibly soft and marshmallowy, deforming where they pressured onto his skin. He savoured the sensation for the brief moment it lasted.

She took a few strokes like that with her hindlegs in his face, slithering her wet anus up and down his cock, before she dropped them to either side of his body. She leaned forwards, looping her forelegs around his neck, gripping his shoulders again with her hooves. She continued sliding up and down his thick shaft.

She pressed her lips against his, surprising him as her tongue invaded his mouth. Her tongue wrestled with his before she broke the kiss for the need of air, a thin line of saliva connecting the two of them together. "Hmhmhm, you like that...? I can feel your big cock getting even stiffer inside of me! It's okay to gush about how marvelous I am, please, be my guest!" she teased, looking deep into his eyes before capturing his lips again in another soul-searing kiss.

She glanced down at her rump and his cock, sticking her tongue out as she concentrated on getting the last few inches in... She was concentrating really hard, it wasn't a small cock by any measure! "Mmmn, your cock is huge, so if I'm not careful..."

And then something gave way! Little Rainbow suddenly threw her head back, tongue flopping out of her mouth, saliva dripping off the tip, her face bright red and tears beading in the corners of her eyes. "AHIIIIII!"

He was all the way inside her ass now, and she tightened appreciatively! "Suddenly going that deep! It's good! It's really good!"

She held him tightly, gripping him like she was drowning, hooves stroking over his chest, while her hindlegs continued to rub teasingly along the tip of his thighs. She raised a hoof and turned her body, going from cowgirl to reverse cowgirl in one easy, smooth motion. She came face to face with Twilight, and stifled a moan as their eyes met, grinning coyly at the other pony. She moved her hips, teasing the purple pony with the sight of his cock filling her.

Once she was nice and comfy in his lap, she reached up and behind her and slung her forelegs around his neck. Her expression showed how totally in control the tiny pony was, her eyes pinched, her tongue extended, nothing but absolute delight in her eyes while he groaned and twisted and writhed underneath her.

"This is a much better spot... I can see how my ass is spreading... I can see your perverted dick getting ready to creampie my pony butt! Mmm, you have to get deeper... Ahhn!"

Her first orgasm made her whole body tremble, the pony smugly riding it out. With her mouth twisted in a snarl and her eyebrows all the way down, she looked more like a ferocious cock-conqueror than the pride of the Equestria Games. Making a glans-shaped bulge in her tiny tummy had drawn her savage side all the way out! "Cum! Fuck me lots with your penis!"

Her switch was flipped, and from here on out she was heart-pupils only. Her head turned this way and that, face glazed over entirely. When she met his gaze, it was with those shimmering, glowing heart pupils. Mostly she just wriggled her hooves in the air, clutched at any part of his body she could find, and let out a continuous series of "Eh! Eh! Weh! Eh!" noises into the air. She sounded more like one of the ponies she was based on than a cartoon horse right now!

"Go ahead! Cum! Ahhhhn~!"

William growled as he came again. He wrapped his arms around the flailing pony as he held her tight against him, his male instincts driving him to shoot deep inside this little firebrand. Not even a cute pony would get out of being stuffed with his semen. No matter how much he let out, she didn't let a single drop spill out, and soon she was bloating so much she she had a tummy bulge!

When her little heart was finally done pounding, Rainbow looked up at her man. Her hooves were still tangled in his dirty shirt. "Hey, you! You better be ready to do that a lot more! You're my owner now, and don't you forget it! If I find out you're planning on not using me like that every day, I'll make sure you're really punished!"

Twilight had been watching the proceedings quietly, but when William withdrew his plump pecker from Rainbow's rear, the alicorn knew she couldn't wait a moment longer. She moved closer, creeping along the bed, and gently placed a hoof on his cheek. "I think I'd like the same now, darling~" she cooed in a soft voice.

From there, she laced both hooves around him, her hips moving energetically as she came closer! "Darling, darling~"

There was a loud clap of his hands slapping onto her little body, gripping her tightly. Holding Twilight with both hands, he moved her onto the bed in front of him. He tangled his fingers in her mane and pressed her head firmly, but gently, to the sheets. She immediately raised her ass pleadingly, shaking it at him. He gripped her butt with his other hand.

His fat cock was stiffening at the thought of defiling such a plush, curvy rear. He smacked that fat ass once, then twice, relishing in how those cute cheeks jiggled before him, the cute pony seeming to be literally the most perfect mate he could have asked for!

Twilight moaned as she was hotdogged by him, that big cock sliding back and forth against the warm, soft curves of her cutie-booty, leaving hot, smelly sperm wherever it touched. The beautiful little pony held tightly onto the bed to try to prevent herself from being swept away by pleasure.

She was making a very naughty sex-face indeed, only witnessed by Rainbow Dash. From where he was, William could only see the back of her lowered head, but the face she was making at the wall was very blissful indeed, like she'd finally found her true calling in life. It was a look of happiness straight out of a porn comic.

"Haaahn~" she weakly cried, swaying her thick hips from side to side, teasing him with her fertile rear. "If... If you're so naughty and perverted you want to stick your dick inside me, then... Then you're naughty!" she finished lamely, lost for words.

William was amazed by just how the cutie's body was reacting! He could tell she wanted it, so he was just gonna have to be naughty with her and grant her what her greedy little hole obviously needed. His cock slid back, then forward, the head suddenly pressing against her hole. Precum was already leaking copiously from the tip, lubing up the fat red head, just enough so that it could begin to slowly press inside that tight, tight ring. His dick went in, thrusting into her tiny body, filling her anus up with his twitching shaft. He pinned her under his body as he drove deep into her butthole.

With one rough motion, he pressed his hips forward, filling that butt up with as much of his dick as he could fit between those vice-like walls. She was so infernally tight, so curvy, so fat assed, so perfect in every way, the mere act of just penetrating her was almost enough to make the poor man spurt, cute whimpers already escaping his lips.

It was almost too big for her, the princess letting out a delicate shriek that startled Rainbow. From where she was sitting, Twilight was barely visible under the male's body, her slender form bearing the weight of his stomach, his head resting on top of hers as they kissed each other... His hips were driving back and forth with all his strength. He was drooling into her mouth, while the pony looked love-drunk, big, throbbing hearts in her eyes. Truly, the magic spell of love had visited this bed tonight~

Twilight liked that veeeery much. She lifted alll the way up onto the tips of her hooves, eyes wide, tongue extending... So vulnerable, so cute and sooo butt-hungry~ Needless to say, her bottom didn't disappoint: it gripped his shaft in a lewd grip tighter and hotter than any pussy, burning up his naughty cock and making it sting. His dick felt itchy...! So itchy, she'd have to scratch it right away... To think such a cute pony would have such a bewitching anus, so teasingly perfect for inciting her partners to pound her as hard as they possibly could.

But that was how it was... The cutest ponies always had the naughtiest buttholes, as if to disarm their partners and make them think they were safe as they sunk their cocks into those greedy, hot holes. Once you were in, there was simply no escape until you'd spunked up their rears again and again and again~ "Mmmph... Ahh, it's way too big! Your penis... Ahhn, your penis is too biiig..." She was thrusting her hips back at her, luring him to hilt and lose his mind to the pleasure of pony.

His cock finally pressed into her body, his eyes shooting wide, a massive pulse of pleasure shaking his frame as he struggled to not just seed her right then and there. Instead, his mating grew rougher, more needy, hips pumping right against that pony booty.

"Mmmmgh!" he groaned, that tight butt just so, so good. It was almost irresistible to the poor human! It had sucked his entire length right in, much like how her cute, pouty lips had. His thrusts became more and more frantic as he pumped into her tight hindquarters, her tip grinding against her ring with every thrust, coming closer and closer to driving it inside, to really making her his mate. He felt trapped, unable to do anything but pump his hips, to moan, his entire body overwhelmed by just how good her hole was.

Twilight howled again as her anus was stretched to its limits. Her head lolled momentarily, eyes rolled back, mouth drooling. She shook as she rode out her orgasm. Rainbow watched as the other girl came again and again, a drunk look of absolute pleasure on her face. Her mouth was fully open all the way, stretched to its limits, tongue lashing in the air. It didn't look like her Twilight's little pink tongue anymore, dripping with William's saliva it was more like some perverted sex-tentacle! She was unable to do anything as she watched them roughly fuck, but try to ignore the wetness of her pussy and the burning heat in her asshole.

The pretty pony was repeatedly thrust into the bed by his insistent, needy fuck-thrusts. Her wide hips were driven into again and again. "Nnnmmm... You're making me a bad pony! I can feel something coming...~" she mewled. She came long and hard, making a lovely, goopy mess.

"This is too cruel... Ahhnn, at least kiss me... You have to at least do that!"

William could hardly refuse such an earnest request, especially when the cutie had been so kind as to surrender her fat butt to his desires. He leaned over, pressing into her back as his tongue licked at her cheek. Then his lips met hers, tongue pressing into the pony's mouth.

His cock was throbbing inside her hole, and finally, he could take no more, hot cum shooting deep inside her tight hole, staining her walls and leaving her so very, very full of his seed. When he drew his cock out of her butt, he'd get to see the full impact of his hard work. Her big butt was shuddering, butthole saying goodbye to his penis with sexy little twitches. Her stretched-out ass was jam-packed with semen, a thick amount of it oozing out of her without his cock to keep it stuffed inside anymore.

One more set of spasms from the purple pony was all it took, her writhing under him reaching a fever pitch as her butthole victoriously dragged all of his semen out of him. A great groaning sounded emerged from William as he shifted his weight on the bed. It creaked ominously as he eased back onto his haunches, lifting little Twilight up into his lap, seating her right on that pendulous, throbbing cock. She loved the feeling of being a small, cute pet in her huge human "teddybear's" lap, letting him grip her ass and use her pony-holes like his personal sex toy. Her little eyes glimmered impishly as she was steadily pumped full of her master's load.

"Mmm, there's so much going into my butt... It feels like he's pumping it non-stop!"

She laid one hoof cutely over her free-flowing rear, barely covering anything, and used the other to give him a little bap on the nose. "B-Bad! You're too rough!"

But then she leaned into him, giving him a little cuddle... "Y-You should snuggle and kiss me before you put it i-inside next time... You, mm, have to ease your partner into things before you put your big penis in them..."

She was too cute, his heart just couldn't take it! He just wanted to keep her in bed and fuck her butt all night long! "Yeah, Twilight," he mumbled, spent cock still leaking patches of seed onto the bed.

Eventually, she sagged, and Rainbow was quick to join her in their new owner's lap.
