Scootaloo frowned viciously as she walked to school, the young mare angry at a lot of things, but most notably the fact that she had slept through her alarm and no one seemed to care enough to wake her in time for school. Though she knew that wasn't true, as her aunts were merely very busy after all the legal trouble they went through, it was still disheartening and made the young mare feel unwanted in the extreme.

Grumbling silently through the town Scootaloo glanced through the window of a cafe and noticed that if the clock on the wall was correct, that she would get to school just in time for first recess. “Well at least I won't have to walk into class midway through a lesson.” Scootaloo muttered, remembering well just how vicious the tongue lashing was when somepony was foolish enough to do that.

It also made her step accelerate slightly, the mare eager to see both her friends, as well as her coltfriend whom she hadn't seen in several months. Upon thinking back to the months she had missed, Scootaloo ground her teeth together, happy that at least she hadn't fallen behind in school, though she missed a good portion of the spring, and was coming back just before summer break. She had missed some of the best time of the year to be a bully, as spring meant track, sports, and outdoor activities, all of which she excelled at.

Imagining all the gloating time now gone, Scootaloo’s mood fell right back to where it was when she had began the long walk to school. A mood that was only slightly elevated when she saw the school come into view, meaning she was only several minutes away from seeing her friends once more.

She wondered if they had gotten some good burns in on Diamond Tiara yet while she was gone, as the blank flank was the perfect target given her peculiar situation. Snickering softly to herself, Scootaloo thought back to a select few of her own burns she had come up with, the filly eager to pull them back out now that she was finally back in school.

Walking through the playground Scootaloo was instantly struck with a sense of strangeness that bordered on disturbing. Ponies played, and ran around, but they did so in an odd manner, with almost every filly she saw sporting a slight bump in their stomach. A passing yellow coated mare with a diminutive horn frowned when her eyes met Scootaloo’s and she huffed before passing the bully by.

Scootaloo couldn't even think of a response in time, the filly used to being on the receiving end of fear, respect and not outright disdain. By than, word of her arrival seemed to have passed through the school yard and just about everypony gave her a sidelong glance, whispering to their friend group about Scootaloo’s return. Most seemed to display an open sense of disgust, while others had a strange eagerness to their faces and words that distressed Scootaloo for some reason.

Out in the open, and with nopony to back her up, Scootaloo panicked, the stares drilling into her and opening up all her insecurities. With mounting panic the filly turned and ran towards the door, ignoring the hushed conversations she passed and making a break for the safety of the halls, and hopefully, her friends.

Once inside, most of the staring seemed to stop, with most ponies too absorbed into their own hobbies and conversations to notice Scootaloo’s entrance. Breathing a sigh of relief, Scootaloo made her way to the stairs that went up to the second floor, knowing that her friends would probably be hanging out near the bathroom on the second floor.

As she trotted to the stairs Scootaloo couldn't help but pick up a few stray strands of conversation, the filly hearing a single name uttered nearly constantly. Diamond Tiara, always Diamond Tiara. The fact that her name was being spoken in such a hushed, reserved and respected tone was almost too much for the filly and she ground her teeth as she walked, her steps slowing as she tried to listen to the conversations she passed by.

“-and then she just said, okay sure, join the line!” One filly exclaimed giddily, a hoof pressed against the slight bulge in her midsection.

“No way.” The colt the filly was talking to exclaimed. “Did she keep going all lunch hour?”

“Uh huh, and than for like an hour after!” The filly gushed excitedly.

The colt sighed, and bit his lip, his eyes staring off into the distance. “She's so hot.”

“Oh yeah.” The filly agreed. “Do you think she has time for us?”

Scootaloo shook her head in shock and continued walking, not wanting to linger near that conversation for too long lest they figure out he was eavesdropping.

Noticing a few teachers leaning against a wall near the teacher’s lounge at the end of the hall Scootaloo trotted over to them, before ducking to the side and opening an unlocked locker, pretending to find something within the messy contents. All while paying close attention to the teacher’s conversation with a keen interest.

“Do you think if I give her another A she’ll spend a little more time with me?” The first, slightly older female teacher asked.

Her conversation partner, a younger, more heavily pregnant teacher shrugged. “Diamond Tiara doesn't like it when we break the rules for her.”

The older mare frowned. “Than what can I do? Its been weeks since we've been, well, alone and I am dying Test Taker, dying.”

The younger mare chuckled and placed a hoof on the other mare’s shoulder. “Oh Sunny, you are not dying. Have you tried talking to Cherrilee? She mentioned that she was working on a mold of her in order to help keep the cravings in check.”

“I guess, but nothing beats when she just fills you ya know?” The older said with a sigh.

Whatever the younger teacher was about to say was interrupted by a pony suddenly stomping up to her and angrily announcing that. “That's my locker!”

Scootaloo closed the locker and turned to the source of the voice, only to blink in shock when the high pitched voice’s owner was not in fact a female. “Button Mash?” Scootaloo muttered in disbelief.

“Yeah, that's me. What are you doing in my locker?” Button Mash pressed, his eyeshadowed eyes narrowing.

“What did you do to your hair, you look like a total sissy.” Scootaloo spat, pointing to the colt’s long, braided locks.

“I do don't I?” Button Mash muttered happily, running a hoof down the braid that cascaded down one side of his head.

Scootaloo merely stood there for several seconds, mouth agape at just how girly Button Mash had become. His hooves were painted, eyeshadow brought out the subtle feminine qualities in his face, and even his voice seemed to have raised a few octaves. As she continued to gawk Scootaloo noticed that he had also braided his tail, making it difficult to hide his maleness from any casual observer.

“What the fuck happened to you?” Scootaloo muttered, partly in disbelief.

Button Mash leaned on the lockers and rolled his eyes. “Oh come on, it's not that weird. Diamond Tiara and Sweetie Belle just like it when I bring out my feminine side.”

“Diamond Tiara and Sweetie Belle? What the fuck does that mean?” Scootaloo muttered, becoming more confused by the second.

Button Mash sighed. “You are like, so getting on my nerves with all the swearing.”

“Shut up and tell me where Sweetie Belle and the rest of my friends are, right now.” Scootaloo demanded menacingly, her nose mere inches away from the feminine stallion’s face.

Rather than be intimidated Button Mash merely shrugged. “They are upstairs hanging out with Diamond Tiara and Silver Spoon like always. Why?”

Scootaloo shoved the male aside and stomped off. “I’ll deal with you later.”

Button Mash shrugged and made his way over to his locker, making sure to sashay his hips like Sweetie Belle had shown him. “I wonder what her problem is?” The male stopped just as he was opening his locker, only now realizing the juicy bit of gossip he hadn't even noticed he had. “Oh I bet he doesn't even know about Rumble!”

The girly stallion clapped his hooves together and spun right around, intent on observing the drama from afar. “Oh this is going to be good.”

An angry Scootaloo hopped up the stairs two at a time, brushing past a strange, trancelike young mare who had a wide smile on her face as she stumbled down the stairs, her back legs not seemingly working. The bully didn't have time to even think about whatever was going on there and roughly shoved her and her friends aside, ignoring their cries of irritation as she leapt up the last of the stairs.

Turning to her right, Scootaloo recognized instantly the familiar spot at the end of the hall where the small, somewhat secret bathroom was, as well as the small sitting area that made for a nice place to hang out. Scootaloo’s hooves stumbled for a moment and she gaped silently, amazed at what she saw standing in her usual hang out spot.

“What the fuck?” She muttered, nearly running face first into an absent minded teacher carrying a large stack of papers.

When the teacher past, and his grumblings with him, Scootaloo was once more greeted by a sight that both terrified and disgusted her in equal measure.

Standing where her, Sweetie Belle and Apple Bloom usually stood were those same mares, as well as Silver Spoon. They appeared to be friends, not only that but close friends judging from how close they stood and how readily they touched one another when talking. Though Scootaloo was angry to find her friends had betrayed her, that wasn't what terrified or disgusted her, no, there was something far stranger at work.

Namely the fact that they were all, very, very pregnant.

Silver Spoon was easily the furthest along, the filly’s belly having swelled to the point that she appeared ready to deliver. After doing some brief mental calculations, Scootaloo quickly reasoned that this was impossible, as she hadn't been pregnant that long ago, meaning she was likely carrying twins, or perhaps triplets. The mare also carried an air of command about her, as if she was in charge, her mere stance and the way she spoke carrying across this unspoken dominance quite well.

Beside her, was a smiling Apple Bloom, who wore a simple black, lace sundress that emphasized her only slightly smaller stomach quite well. The farm pony seemed enthralled by the conversation, a blush on her face, something that only seemed to emphasize other physical changes that came in the shape of piercings and makeup, two things Apple Bloom had always said she wouldn't do.

Black lipstick graced the filly’s face, as well as undershadow and painted eyelashes, the young mare having apparently given into some desire Scootaloo had never noticed before now. The changes werent just skin deep though, and as she watched Apple Bloom seemed to tease the other two mares fairly constantly, though not in the way Scootaloo would have assumed. Apple Bloom’s hoof seemed to always stray a little further than what good taste might dictate, caressing the other pony’s faces and sides and it was clear just at a glance that she wanted to fuck them both, possibly at the same time.

Sweetie Belle appeared the most normal, despite having the third largest stomach, as the only noticeable change that had occured was how she flirted back openly with both Silver Spoon and Apple Bloom. Her physical changes were minimal, though she did wear bright red lipstick, something Scootaloo distinctly remembered the unicorn swearing off at a young age.

Unbeknownst to Scootaloo the crowd that had been passing her by had dissipated somewhat, giving the three ponies a clear view of the gawking Scootaloo standing down the hall from them. Apple Bloom seemed to notice first and grabbed her friends attention before turning and gesturing to Scootaloo.

As all three sets of eyes settled on Scootaloo, the bully realized where she was, and the true scope that such a set of strange changes indicated.

Shaking her head, Scootaloo set her jaw and stomped up to the trio, intent on getting answers, and ripping a certain well endowed filly a new one. “What the fuck is going on?” Scootaloo demanded.

Apple Bloom raised her eyebrow and snorted. “Well ain't that a fine howdy do?”

“She is rather rude, isn't she sweet stuff?” Silver Spoon replied, elbowing Apple Bloom.

“Quite so.” Apple Bloom agreed.

“And demanding after not seeing us for months.” Sweetie Belle tsked. “It's nice to see you too Scootaloo, how was your trip to Canterlot?”

“It was fine, but that's not what-” Scootaloo began, only to get cut off by Silver Spoon.

Who tapped her chin thoughtfully. “Why did you go to Canterlot anyway? And for so long to, I bet your going to have to take summer classes now.”

“There was an… issue with the adoption, my father wanted to claim guardianship.” Scootaloo shook her head. “That doesn't matter now though, that's not what were talking about.”

“Oh but it is.” Silver Spoon pressed. “Were all quite concerned about what was happening after hearing about it through Cheerilee.”

“Yeah, no offence but that sounded pretty crazy Scootaloo, are you sure your okay?” Sweetie Belle asked, stepping forward and placing a painted hoof on the other mare’s shoulder.

At the sight of the red hoof something inside the bully snapped and she knocked aside her former friend’s hoof. “Tell me where Diamond Tiara is.”

“Why?” Apple Bloom asked, while leaning heavily on Silver Spoon. “Cus if your here to start trouble I would advise against it.”

Apple Bloom grit her teeth and stuck her face into her friend’s. “And who is going to stop me, a bunch of pregnant mares?”

Apple Bloom raised an eyebrow and glanced over to Sweetie Belle who sighed, took a step back and yelled at the top of her lungs. “Titanic!”

The floor rumbled, and in the distance the crowd parted, allowing a giant mountain of muscle pass through the crowd, admitting a slate grew unicorn mare roughly the size of a small mountain of weights. “Is someone bugging you?” Whispered the mare, her eyes narrowing at the sight of Scootaloo, her titanic triceps bulging as she glared down at her.

“Titanic Triceps, this is Scootaloo, she was just being a little rude.” Apple Bloom remarked with a smirk, gesturing to Scootaloo.

The pegasus gulped and took a nervous step back. “And I was just about to apologize.”

The massive pile of muscle lifted an eyebrow and glanced back and forth from Apple Bloom to Scootaloo. “Well, get on with it.”

The young pegasus ground her teeth together before turning back to her former friends. “I’m sorry.” Muttered the young mare.

“For?” Apple Bloom inquired, leaning forward expectantly.

Sweetie Belle sighed. “I think that's good enough, right Silver Spoon?”

The other mare shrugged. “I don't know, I’d feel a lot more forgiving if I had some extra money for lunch.”

Sweetie Belle rolled her eyes and nodded to the huge mare standing a few feet away. “That's all, thank you Triceps.”

“Sure thing Sweetie.” Triceps said, before suddenly blushing and leaning forward. “Do you think maybe you could put in a good word with the boss?”

“I will, don't worry.” Sweetie Belle replied, patting the muscled mare on the shoulder.

Who promptly turned and skipped away, clearly delighted by the prospect of getting into Diamond Tiara’s good graces.

Scootaloo shook her head and grit her teeth, reminding herself what had just happened, and what it meant for their friend group in particular. “Don't worry Apple Bloom, Sweetie Belle, I’ll figure this out and save you from your brain washing.” Announced the courageous bully.

The three ponies shared a confused look before erupting in laughter, leaving an increasingly angry Scootaloo to sit there and fume all by herself. “What? You three are obviously brain washed somehow, like everyone else in this crummy school!”

“Oh please, it's not some sort of spell, she's just get the best fucking dick in the school.” Silver Spoon exclaimed.

“W-what?” Scootaloo stuttered, taking a step back in shock.

“You heard her, Diamond Tiara’s got a great fucking dick.” Apple Bloom added with a surprising amount of sass.

“But your dark clothes, and Sweetie Belle’s lipstick, nevermind your, that.” Scootaloo exclaimed, pointing to the mare’s bulging midsections, and swollen stomachs.

“I always wanted to wear darker stuff, D.T just gave me a little push in the right direction.” Apple Bloom exclaimed.

“Yeah, and I was just nervous about wearing that stuff around you because I know how much you hate girly stuff.” Sweetie Belle added.

“Face it Scootles, your friends are better off without you.” Silver Spoon shot back, sneering at the other filly.

“Well that's a bit much. Also, Scootles?” Apple Bloom interjected.

Silver Spoon shrugged. “It's not great, but you gotta admit it is kind of demeaning.”

Sweetie Belle sighed, and ran a hoof down her face. “Would you two shut up already?”

“Where is Diamond Tiara?” Scootaloo demanded, her jaw set. “She has to be at the heart of this whole brain washing thing.”

Silver Spoon smirked, sharing a glance with her fellow pregnant mares. “I don't know, where do you think she is?”

Scootaloo blinked, and was about to fire back with a witty retort only to catch what sounded like a moan from nearby. The filly’s eyes narrowed, and she slowly turned towards the bathroom, her confusion growing as she realized that the moan she had heard was from a male, but not only that, one that was familiar.

“No.” Scootaloo muttered in disbelief.

The pegasus trotted towards the door in a daze, not wanting to believe what her ears were telling her. Behind her, the three pregnant mares all shared mixed expressions, the group remaining silent as they let Scootaloo find out for herself just what was going on behind the closed door.

Pushing open the heavy object, Scootaloo peeked into the bathroom and was stunned to find exactly what she feared she would.

There in the center of the floor of the bathroom was a small makeshift bed constructed out of a gym mat and several pillows and blankets. Upon which was Diamond Tiara herself, who was laying on her back, her side presented to the door, allowing Scootaloo to see the entirety of the mare, as well as the stallion currently riding her cock. A stallion who was none other than Scootaloo’s now ex coltfriend, who, though had not changed as much as Button Mash, certainly looked different.

He had grown his mane and tied it into a ponytail, held together by a pink band. Other than that he wore a small pink bracelet on his right forehoof. At first he didn't even seem to notice Scootaloo’s entrance, the colt bouncing eagerly on the thick cock wedged firmly inside him. His breathing was heavy, and his body twitched occasionally, though his pleasure was somewhat restricted by a ring on his average length cock which stopped him from orgasming. Still, that didn't stop his dick from leaking a constant stream of precum that dribbled down his length and onto Diamond Tiara’s fur.

“Oh hi Scootaloo.” Diamond Tiara greeted, the filly raising a hoof and waving at the bully as if she wasn't currently balls deep in said bully’s coltfriend at that very moment.

“Whuh?” Scootaloo muttered, her brain only half working as it was too shocked to truly process what was going on.

Sure she had heard what was happening and had a good idea what was going on, but Rumble wasn't gay, he didn't even like being on top, as the colt had told Scootaloo that it was the mare’s job. Now, here he was, riding a thick mare cock and loving it so much that he was both moaning like a whore, and dribbling like a faucet.

“What did you do?” Scootaloo demanded, taking an angry step forward.

Diamond Tiara shrugged. “Nothing really, I just propositioned him and he accepted, isn't that right Rumble?”

The colt was too far gone, his eyes were glazed over and his tongue had fallen from his mouth. His entire body seemed to move on auto pilot in the service of the pillar of mare meat currently impaling him. After staring at him for a few seconds Diamond Tiara shrugged again. “Sorry about that, Rumble seems to get pretty in the zone as it were. Isn't that right my little slut?”

“Yes, mistress.” Rumble droned.

“Your not going to get away with this.” Scootaloo declared. “I’m going to figure out how you’ve done this and give everypony their brains back!”

Diamond Tiara rolled her eyes and tucked her forehooves behind her head, relaxing as Rumble continued to ride her cock. “Good luck, have fun spinning your wheels.” She remarked dismissively before turning her attention back to the colt currently bouncing on her crotch.

Scootaloo ground her teeth together, temporarily paralyzed by indecision as she stared from her ex colt friend to Diamond Tiara and back again. With an angry huff, she decided it wasn't worth tangling with that giant muscle pony and turned to leave, pushing past the door and angrily stomping past the looks of her former friends, and Silver Spoon.

“What's that? Not going to join in for our mid morning orgy?” Silver Spoon yelled after her.

Scootaloo’s jaw grit tighter and she ignored the taunt entirely, roughly shoving her way through the small crowd that still lingered and making her way downstairs.

Leaving three mares to shrug and peek their heads into the bathroom where Diamond Tiara was enjoying a nice relaxing ride. “Hey sugar, was that part of the plan or am I missing something?” Apple Bloom inquired.

Silver Spoon rolled her eyes and clopped a hoof upside the filly’s head. “Of course that's part of the plan, don't you remember.”

“Not Silver, she was currently deep throating my cock when you were talking about the plan.” Diamond Tiara admonished, making the older filly blush and rub the back of her neck.

“Err sorry about that Apple Bloom.” Silver Spoon apologized.

“So what does Scootaloo running off have to do with the plan?” Sweetie Belle asked, cocking her head.

“We know exactly where she's going, meaning we know exactly what do once she gets there.” Diamond Tiara explained.

“Ooh, now I get it.” Apple Bloom muttered.

“You don't get it do you?” Silver Spoon dead panned.

“Not a clue.” Apple Bloom admitted.

DIamond Tiara rolled her eyes. “Girls please, I’m trying to relax a little before class, can we please talk about this later? I’m sure Silver Spoon can fill you in during the meantime.”

Apple Bloom and Sweetie Belle both winced. “Sorry Diamond.” They said in unison.

“Don't worry about it, just give us a little privacy for a few more minutes.” Diamond Tiara commanded, her attention returning to Rumble, who had slowed somewhat.

“Right, sorry Diamond Tiara.” Silver Spoon muttered before grabbing the two other mares and yanking them back out of the bathroom by the scruff of their neck.

“Now than, where were we?” Diamond Tiara muttered, looking up to a still distant Rumble. “Oh right, I was going to let you cum, wasn't I?”

“Yes mistress.” Rumble droned.

Diamond Tiara rolled her eyes and cuffed the colt upside the head. “And cut it out with the yes mistress crap, I indulged your weird fetishes enough today.”

Rumble shook his head vigorously. “Err sorry Diamond, but you know how much I space out when getting a good pounding.”

“I know, but I want you aware and a part of the fun, besides, I’m going to cum pretty soon and I want you to work my cock good and hard.” Diamond Tiara commanded. “Oh and make sure to beg for it, I want to hear that girly voice that you've been practicing.”

The colt blushed profusely. “You mean like this?” He offered, his voice having risen several octaves, to the point that he no longer even sounded like a colt at all.

“Wow, you are nailing that voice thing.” Diamond Tiara complemented. “You got the cadence and everything down pat.”

Rumble blushed even harder, the colt’s hips having stopped moving as he was overcome with emotion. “Err thanks Diamond, I’ve been working real hard on my slutty voice.”

“Well I think it's adorable.” Diamond Tiara whispered, pulling the colt in close and planting a kiss on his lips. “Ready?”

“Always.” Rumble replied confidently.

And like that, the colt was off to the races, his hips moving instinctively in a manner that Diamond Tiara would both physically enjoy, as well as like the look of. The sashay of his hips, the way he tossed his head back and moaned aloud, it was in service of the futa filly and her enormous cock. This desire to please was exemplified in his every movement, the colt shaking his hips, moaning, shifting and squeezing in all the ways Diamond Tiara liked.

Which wasn't to say he didn't enjoy himself immensely, as the colt had learned to relish the sheer debauchery that he now regularly engaged in. One part of it was the physical aspect of it, the way his hole was spread wide by the thick mare cock, his body having been stretched and shaped to better pleasure the enormous pillar of mare meat. The other half of it was the psychological thrill of pretending to be this hyper feminine version of himself. A version that was becoming more and more real each time they fucked, to the point that Rumble found himself using his slut voice in class and on the school yard.

None of that mattered right now though, as he had a job to do, and a mare to please, and Diamond Tiara was not someone that you ignored for long. She may be forgiving, and even kind, but Rumble knew well how bad it felt to see the mare’s disappointed expression pointed at him, and that was something he could never forgive himself for.

Raising his hips high into the air, the colt used the surprising amount of flexibility to pull nearly the entire way off Diamond Tiara’s cock before throwing himself bodily backwards and impaling himself once more on her shaft. This long, deep thrusts were incredibly physically demanding, as Diamond Tiara’s cock was truly enormous, and made it difficult to bounce like that on without proper pre fuck stretching. Something Rumble always made sure to do, as no effort was too much to make sure that the queen of the school was able to enjoy herself as much as possible.

The colt groaned, his hips beginning to ache as the minutes passed by. Thankfully he had managed to work up to a good, steady pace, the sound of his balls slapping against her lower stomach becoming near constant. Her balls were massive, and every time their hips met, Rumble could feel them press against his ass, reminding him that she was the alpha male here, and that he was little more than another mare that came begging for dick.

He groaned aloud, making sure that even his moans and the sound of his lust was several octaves higher, the colt knowing well just how much DIamond Tiara enjoyed hearing her sluts enjoy themselves. His hooves pressed against the makeshift bed, the colt having long since learned how to make use of the relatively little support it gave him while still pleasuring the mare’s cock to perfection.

Something he did by squeezing with his internal muscles, his ass milking her cock for all it was worth, the colt desperate to eek out another orgasm from the futa filly before the bell rang and they had to end their session there. Feeling another twitch come from Diamond Tiara’s cock, Rumble looked down and noticed that his partner now sported a massive smile. This combined meant that she was coming close, and he needed to do one last thing to get the cum he so craved.

“OH Diamond Tiara I’m so close, can I please take off the ring?” Rumble begged, making sure to use his slut voice while still grinding his hips against the filly’s crotch.

The effect of having her cock buried to the hilt in Rumble’s tight yet welcoming ass, while he grinded hard against her crotch was a pleasant one and Diamond Tiara smiled a little wider. “Well you have been doing such a good job over the last month…”

“I’ve been working so hard to please you my mistress, please let me cum.” Rumble begged, his lip quivering as he stared down into Diamond Tiara’s eyes.

The filly smirked, while running a hoof down the quivering colt’s side. “Have you been making sure to use your hole every single day?”

Rumble nodded eagerly, his hips continuing to grind away as he spoke. “Absolutely mistress Diamond, I fuck the toy you gave me every single day for an hour.”

“ANd have you been keeping the ring on at all times?” Diamond Tiara asked, lifting an eyebrow.

“Yes mistress!” Rumble replied eagerly.

“As well as practice all your stretches?” Diamond Tiara continued, driving her question home with a sharp thrust of her hips.

The colt stifled a moan by biting his lip, while nodding his head eagerly.

“So long as you make sure not to get my coat messy with your cum, than I supposed I can let you finish this one time.” Diamond Tiara concluded.

“I won't let you down!” Rumble declared.

“See to it that you do not.” Diamond Tiara replied only semi seriously.

Reaching down, Diamond Tiara pressed a hidden button on the cock ring, making it split in half and release the colt’s cock. Acting quickly, Rumble grabbed the ring and placed it on the ground next to the makeshift bed before grabbing an average sized condom and wrapping it around his cock.

With that done, Rumble gripped the bed in both hooves before giving his butt a little wiggle and making sure Diamond Tiara’s cock was as deep as possible, before smiling contently. “Ready?” He asked.

“Ready.” Diamond Tiara grunted.

With that same giant smile pressed firmly into his features, Rumble shifted his hips forward before slamming himself back down against the filly’s crotch. He continued this same movement over and over, the colt imapling himself repeatedly on the futa filly’s dick. His speed wasn't truly remarkable, as Rumble was held back by his own less than stellar physique, nor was his skill particularly exceptional. Yet Rumble was still managing to get the usually quiet filly to moan aloud, his hips moving with such sheer desperation that he was managing a feat most could not.

Diamond Tiara moaned long and hard, thrilled by the way Rumble slammed himself against her crotch over and over. His ass clenched tightly around her shaft, the colt’s hole expertly able to milk the futa mare’s cock in a way few else could.

In moments, Diamond Tiara felt the orgasm that had begun to slip into the back of her perception rocket to the forefront of her thoughts. The filly felt for a moment that she should participate a little more directly, by maybe grabbing the colt’s hips or thrusting back, only to remember the fact that he enjoyed being used. Putting that thought out of her mind, Diamond Tiara focused on enjoying herself and relaxing as much as possible before she got back to class, and had to focus once more.

Time flew by quickly, with Rumble eager to milk the cum from Diamond Tiara’s cock and doing everything he could to reach such a conclusion. The colt himself bit his lip tight, his moans coming out as little more than half hearted whimpers that Diamond Tiara could hardly hear. His cock twitched and jumped each time their hips connected, and the futa filly’s cock plowed as deep as possible into his plump posterior.

His flanks jiggled, with every tiny movement, the colt’s form having grown more and more feminine the more he fucked Diamond Tiara’s massive erection. Together the two pony’s half whispered moans joined the soft plap of Rumble’s plump ass and purt balls slapping into Diamond Tiara’s body, droning out any sound from outside.

In that moment, in that instant there was only each other, and to Rumble, there wasn't even that, for their was only DIamond Tiara’s cock. It was all that mattered, all that he cared about, and all that he craved. With a pace that bordered on feverish, the colt slammed himself against her, desperate to feel every inch of mare cock inside his needy hole.

His tight, well trained internal muscles squeezed down on her cock, expertly working her shaft in order to give her that much more pleasure and bring him that much closer to his goal of being filled with seed. A twitch was all it took for Rumble to know that her orgasm wasn't too far away, the futa filly telegraphing very subtly that he was about to get what he wanted. Which was good news for the colt, as he was currently desperately holding of his own orgasm, not wanting to cum before Diamond Tiara had.

Not only would it have been disrespectful, but it would also obscure his ability to milk her cock properly, and that was not something that Rumble would allow. He would give her all the pleasure she deserved and then some, the colt bound and determined to earn himself more time spent with the filly’s cock buried deep in his slutty hole.

His pace quickened, his hole squeezed tighter, his moans rising to a fever pitch as his own orgasm and Diamond Tiara’s was nearly there.

Wanting to add that last bit of pleasure Rumble let loose a high pitched moan of pleasure, followed by whimpering Diamond Tiara’s name over and over.

The combination of hearing his high pitched voice and the way he uttered her name over and over was too much for the young filly and she reached forward and gripped his hips before slamming herself inside him with all the force he could muster. The act of having her cock buried utterly into the colt’s tight hole was pleasurable, but far more pleasurable was the high pitched cry of pleasure he gave when Rumble felt his prostate get nearly crushed beneath the powerful thrust.

His tongue fell from his mouth and his entire body began to twitch as he felt seed begin to erupt inside him. His own orgasm was meagre in comparison, his leaky cock having finally twitched its last before filling the condom with his weak, watery cum. Throughout the filly’s entire orgasm Rumble maked sure to keep his back arched and his hips pressed firmly against Diamond Tiara’s not wanting to miss out on even a single drop of her perfect cum.

His efforts were rewarded with a belly that swelled exponentially with seed, his taut stomach stretching and distending as it was forced to take more cum than what should be possible. He had practiced though, and numerous enemas, both traditional, and given to him in the form of having his insides flooded with Diamond Tiara’s thick cum had given Rumble the ability to hold it all with little discomfort.

An ability that was put to the test as the colt’s stomach continued to grow and grow until he winced as he felt himself stretched to a greater amount than ever before.

Seconds slowly ticked by, the colt’s own orgasm having petered off long ago, with Diamond Tiara only beginning to slow after several consecutive minutes of orgasming.

His chest heaving with exertion, Rumble looked down in shock, silently amazed that she had both produced so much, and that he had been able to take it all. It was clear even at a glance that it was more than normal, the colt’s cock obscured by his now quite large belly.

Every slight movement seemed to make his stomach slosh with cum, and the colt marveled at the sight that beheld him. His own hoof gently rubbed the taut flesh, baffled by his own apparent skill. “Woah.” He muttered, the colt feeling the last few spurts of cum joining the veritable ocean now swimming inside him.

Diamond Tiara herself seemed exhausted for a moment, the filly laying on her back, hooves splayed in all direction as she breathed harder than even Rumble did.

“What was the occasion?” Rumble asked.

Diamond Tiara chuckled and shook her head. “Oh nothing, I was just thinking of making a new friend.”

Rumble lifted an eyebrow before thinking back to the brief moment Diamond Tiara had shared with Scootaloo. The underlying intention that Diamond Tiara was going to seduce the headstrong filly was a pleasant one to Rumble, and he hoped against hope that by seducing her, that he would be able to be friends with her again as well.

He sighed, and reached towards the butt plug laying a few feet away, only to stop when he realized his belly was now in the way. “Err, a little help?” He asked.

Diamond Tiara chuckled and handed him the butt plug, the filly watching closely as Rumble slipped up her length, the colt’s eyes screwed tight as he focused on not spilling a drop. With precision that bordered on the masterful, Rumble slipped off the last inch of Diamond Tiara’s cock and swiftly rammed the butt plug into his hole, burying the plastic length inside him and stopping so much as a single drop from escaping.

“Whew, that was close.” Muttered the stallion as he stepped away from his lover.

“I’ll say, your going to have to teach that one to Sweetie Belle, as no matter how many times she does it, she always makes a mess.” Diamond Tiara chuckled, only to motion towards the condom still hanging from the colt’s cock. “Make sure you drink it all.”

Rumble nodded, gripped the condom, pulled it off his cock before pressing the hole against his lips and tipping it back. Drinking down his weak and watery load was unpleasant compared to Diamond Tiara’s thick and tasty seed, but it was her will, and he would not complain. With that done, he swallowed heavily before tossing the condom into a garbage can.

Diamond Tiara stood on shaky hooves, giving each of her limbs a firm shake in order to return strength to them. “Ready?”

Rumble nodded, blushing slightly as the filly held open the door for him. “Ready.”

As if on cue, the bell rang, signalling the resumption of the school day, and another step closer to Diamond Tiara’s final victory.
