Author's Notes:

This chapter may contain weirdness. You have been warned.

The Castle of Friendship was usually a somber place at night, the occasional candle giving a faint flickering light, its huge halls eerily empty and quiet. Tonight however, it was seeing an unusual level of activity, cries and hurried footsteps breaking the stillness. Sunset gave no heed to the ruckus her heeled boots were causing, too focused on running from corridor to corridor, looking for her friends. But, after almost an hour of panicked searching, the human’s mad dash had slowed to a crawl, her legs barely managing to finish climbing one of the great staircases that plagued the castle.

“Okay this is just silly.” Sunset groaned, panting slightly. She dragged her feet over the last few steps, finally reaching the landing. “*Ugh*, where am I now?” She took one look at her surroundings, then promptly threw her arms into the air. “OH COME ON!” She shouted, red in the face. “How in the hay did I get to the front door again?! I went up three flights of stairs!” Her frustrated screams echoed around the crystal walls, seeming to come from everywhere at once.

Sunset was known for being a little bit impulsive, and she usually did her best to deny it. But right now she was starting to see her friend’s point. After just a week of radio silence from Twilight and her twin, she had suddenly decided she needed to investigate, in the middle of a sleepless night. Without thought she had jumped on her sleek motorcycle, tore through the town like a madwoman, almost crashing several times; she didn’t even call her friends before diving into the portal. Her fears had been confirmed when she was greeted with cries and yelps, and her frenzied race had proceeded on foot. If she had been less panicked she would have realized the shouts were bouncing around the crystal walls, leading her into a wild goose chase through the maze-like corridors.

“I swear, I feel like I’ve been running around this castle for months…” She took a few moments to catch her breath, hands on her knees. “Okay Sunset, get yourself together, Twilight might need you… both of them might.” She closed her eyes, listening hard, but the only thing she could hear was her own raged pants. “Right, can’t hear them anymore. It’s fine, that doesn’t mean anything. Just stay calm.” Sunset eyed the entrance hall, trying to remember which doors she had already tried. After a moment of hesitation, she took one at random, sighing. “I just hope there are no stairs this way…”

After half a dozen flights of stairs, Sunset was starting to think the Castle was sentient, and that it was trying its best to annoy her. She was seriously considering breaking through the walls to make her own way when she finally stumbled on a corridor that didn’t look like all the others. She paused, looking around in confusion. This hallway was definitely special: the furniture, decorations and pictures lining the walls gave it a homey feel, much more than the rest of the sterile and cold castle.

Sunset peered curiously at the pictures, and a small smile blossomed on her lips despite her fears. Most of them depicted Twilight and Spike, at various stages of their lives, often accompanied by what Sunset could only assume were Twilight’s parents. With a pang of nostalgia, she also noted that Princess Celestia appeared in a few of them, sometimes hugging a little purple filly with her wings, or embracing a teenage Twilight with her long slender neck. Sunset gulped; that had once been her life. She remembered vividly how soft those white feathers felt, how warm Celestia’s embrace was, how gentle the Princess could be when she tucked her to sleep with a goodnight kiss on the forehead…

Sunset blinked, taken out of her sad thoughts, surprised by the state of one of the photos: the edges were blackened, torn, the image distorted and yellow. Did it fall into a fireplace before being fished out? Looking more carefully, she realized that most of the furniture also showed signs of being burnt, as if everything had been rescued from a house fire. Dressers, vases, bookshelves… All carried several black scars. Sunset carefully ran her hand over the charred surface of a horse head statue, a good chunk of its face eaten away by flames.

It suddenly clicked in Sunset’s mind: Tirek, a name she had learned through her correspondence with Twilight. The alicorn had been sparring with the details of the fight itself, but Sunset did remember a line about Twilight’s old home being blown to pieces during her scuffle with the centaur. And if the charred furniture was what Twilight had rescued from her old home…

Sunset straightened, her gaze sweeping down the corridor. She was now convinced that she had found Twilight’s living quarters, the alicorn surrounding herself with her old memories to make the empty cold castle feel like home. And if her hunch was correct… THERE! A door emblazoned with Twilight’s cutie mark! Her room! It was the middle of the night, and since the lab had been empty, there really was only one place where Twilight would be. Unless something bad really had happened. She gulped, then carefully tip-toed her way to the door, listening for any sign of life inside. She didn’t hear anything, but she did notice that the door was slightly ajar.

After a moment of hesitation, Sunset brushed the door open, silently slipping inside Twilight’s room. She quickly spotted the bed, and a shiver of dread ran down her spine when she saw it was empty. The covers were meticulously done, not a crease on the fabric. Actually, the whole room seemed to have been thoroughly cleaned. Sunset sniffed, a faint scent of mint making her blink. Someone had used an air freshener spell very recently, if only Sunset had her horn she would be able to tell when it had been cast, and by whom…

A sound made her head snap to her left, her eyes settling on a small door, probably a bathroom. Sunset could hear muffled splashing sounds coming from the other side, as well as… humming? That was Twilight’s voice! Sunset quickly reached for the door, hope flooding her heart, and knocked three times. Before she could call out, Twilight’s voice rang from inside.

“Come in!”

Sunset sighed in relief, all tension fleeing her body, so happy she felt light headed. Twilight was fine, she had been worried for nothing. She gave herself a moment to compose herself, then stepped into the doorway. Twilight’s bathroom was lavish and wide, it could probably fit Sunset’s whole apartment inside. The bathtub alone was as big as a pool, the water inside covered in a layer of bubbles. And there, with her back against the far edge of the pool, sat Twilight Sparkle, her wings splayed lazily. She had her eyes closed, an expression of complete contentment on her features.

“See,” Twilight began, still reclining comfortably. “I told you finding the kitchen wouldn’t be so hard.”

“Yeah, this castle is a piece of cake.” Sunset said with a smirk, crossing her arms over her chest.

Twilight’s eyes shot open, her limbs flaying in surprise. She slipped backwards, her head disappearing under the soapy surface. Sunset snorted in humor, watching the alicorn flapping around like a sparrow in a fountain, before Twilight’s head broke the surface. The princess had a flabbergasted expression, a crown of bubbles atop her head.

“Sunset?!” Twilight yelped, sitting back on her haunches. “What in the name of Celestia are you doing here?”

Sunset’s eyebrow rose, a sardonic smile appearing on her lips. “Oh no, you don’t have to pretend you’re happy to see me Twilight. Oh, I’m fine by the way, glad you care so much about your friends.”

“Uuuh, what?” Strangely enough, Twilight was doing her best to surround herself with a thick layer of bubbles, her wings quickly reaching around the water for more. “What do you mean?” She said with a fake smile. Sunset shook her head, rolling her eyes, then uncrossed her arms. She waved her magical diary in the air, her brow furrowing. Twilight blinked when she recognized the book. “Oh!” Understanding flashed across Twilight’s features, then she seemed to deflate. “Oooooh…

“Yeah.” Sunset tsked, unimpressed. “Remember when you promised to keep in touch while you two were experimenting?” She tossed her diary on a counter, then gave Twilight an accusing stare. “I knew I should have made you Pinkie promise.”

“I’m sorry Sunset,” Twilight winced, guilt wracking her. “I guess I lost track of time…”

“Having too much fun with Twily?” Sunset snarked. Twilight tensed, her wings going stiff. “I bet you’ve been experimenting nonstop for days.”

“Yes… Experimenting.” Twilight gave an unconvincing fake laugh, her smile crooked. “Science and stuff…”

Sunset sighed deeply, too drained of energy to stay mad very long. “It’s fine, I really shouldn’t have jumped to conclusion.” She winced, pulling on her shirt, the damp fabric clinging to her skin. “Ugh, I’m all sweaty.” She shrugged off her leather jacket, folding it next to her diary. “Mind if I join you?”

Twilight gulped, visibly uncomfortable for some reason. “Hmm, I don’t know if…” Her eyes went wide as Sunset took her shirt off, exposing her black sports bra. The alicorn took in the woman’s generous curves, her gaze following a drop of sweat trickling over Sunset’s glistening chest, before it disappeared in the deep cavern between her breasts. “Come on in…” She said breathlessly, not really thinking anymore.

“Thanks.” Sunset said simply, brushing over Twilight’s strange reaction. The nerdy alicorn was probably just feeling guilty or something. “It’s been so long since I could take a bath with someone.” She sighed contently, slipping off her skirt and leggings. Now in her underwear, she took the time to stretch back, popping her stiffened back, unwittingly pushing her chest out. “Friendly advice: don’t try to propose communal bathing with humans; they get very strange ideas from it.”

“Gaaaah…” Twilight had her mouth open, staring. “DD cups… No, E? Fun size… Motorboating…”

“What’s that?” Sunset asked, tiling her head. When Twilight just sat there, a dumbfounded look on her face, the former pony just shrugged and reached back. “I really hate these.” She grumbled, fiddling with the hooks of her bra. “But human teats are really bothersome without… Ah, there we go.” Sunset tossed her damp bra next to her clothes, happy to be rid of it. “Now I can breathe better.”

“E… definitely E… Firm… Pear shaped… Bouncy…” Twilight mumbled. Sunset quickly slipped out of her panties, and the alicorn’s eyes drifted lower. “Natural… Fluffy bush… Carpet matches the drapes…”

Sunset put her panties away then slipped into the bath, sighing contently. The water temperature was just right, the warmth doing wonders on her tired calves. She carefully wadded into the deeper end, the water coming to her thighs. She exhaled deeply as she lowered her tense body into the bubbly surface, washing away her exhaustion. She started scrubbing herself, humming happily. She was in heaven and she freely indulged on the luxurious facilities. She was about to ask if Twilight wanted to wash her back when she heard the bathroom door click open, followed by the sound of bare feet pattering on the tiled floor. She turned, and smiled when she saw who the new arrival was.

“We need more juice-boxes.” Twily called, a straw between her lips as she slurped on her apple juice. “I made a quick inventory, and I didn’t plan on us needing this much hydration, so our supplies are inadequ…” The girl stopped dead on her tracks, finally realizing there was someone else in the pool. “… Gah?”

“Hey Twilight… I mean Twily!” Sunset called happily. She rose from the water, bubbles clinging to her bare skin. “Sorry to drop by like this, but I was really worried about you two.”

Twily squealed, shrinking back self-consciously. She blushed and tried to adjust the towel she wore around her chest, but with a juice-box in each hand, she just managed to undo the knot and make it worse. She eeped in horror as the towel fell to the floor, revealing her naked body. Twily quickly crossed one arm around her breasts, while she covered her pubis with the other.

Sunset rolled her eyes, gesturing to the squirming nerdy girl. “See? Humans.” Sunset shot to Twilight. The alicorn was looking at Twily with wide eyes, hesitating, as if she wanted to go to her twin but couldn’t get out of the bath. Sunset quirked an eyebrow, but didn’t dwell on it, choosing instead to wade to the shallows and reach for Twily. “Come on, we are all friends here, no need to be embarrassed.” She extended her hand, inviting the trembling girl closer.

Twily’s gaze quickly flew from Sunset to Twilight, her eyes flicking towards Sunset’s lower body from time to time, her blush redoubling. She shot an imploring gaze to her double, asking for directions, but Twilight was too busy staring at Sunset’s breasts, a dribble of drool running down her cheeks. Twily squeaked when Sunset’s hand unexpectedly landed on her shoulder, the older girl sporting a reassuring smile.

“Don’t worry about me Twily, I don’t care, I’m an Equestrian too, remember?” Sunset cajoled. She guessed that Twily was hesitating because she thought Sunset, as a human, would be weirded out. After all, the nerdy girl was obviously comfortable being naked around Twilight. “Just imagine I’m a pony too, it’s fine.” Sunset tugged gently, then a little harder, prepared to drag her into the bath, being both taller and stronger. She grinned when the smaller girl didn’t resist any longer and followed her obediently.

The two of them wadded into the bath, Sunset leading the red faced girl towards Twilight. The alicorn gulped as they approached, squirming strangely on her haunches, as if trying to hide something. Sunset didn’t think much of it: these two were always a little strange. Not Pinkie Pie strange, but still. She carefully lowered herself, taking a seat next to her pony friend, Twily following suit next to her. The juice-boxes sat forgotten on the edge of the bathtub, Twily doing her best to sink into the knee-deep water, her long purple bangs covering her breasts.

Sunset smiled wide. It had been much too long since the last time she had shared a bath with friends, she had missed this more than she had imagined. The last time she had tried in the human world had been during her ill fated relation with Flash Sentry. Sunset rolled her eyes at the memory: he had been the first human to actually accept her invitation, but like every other human he had misunderstood what the invitation meant. She had learned her lesson after that one.

“Hmmm, this is nice.” She sighed happily. Sunset reclined against the edge of the pool, enjoying the feeling of weightlessness as her breasts floated on the surface. Out of the corner of her eye she could spy Twilight stealing glances at them, but she didn’t think much of it. The alicorn was probably just curious about them. “So,” she turned to Twily, the girl doing her best to disappear behind a curtain of purple hair. “what have you two been up to?”

“Oh… experimenting…” Twily mumbled. “Science and stuff…”

Sunset snorted with humor. Those two were definitely alike. “Yeah, I can imagine. But what kind of experiments?” She nudged Twily with her elbow playfully, making the girl squeak again. “Don’t forget I’m a scientist too. I’m not a theorist like you two, but I can find my way around a lab.”

“Well… we’re in the middle of a… biological experiment…” Twily bit her lips, squirming cutely. “With a psychological component…”

“Sounds interesting.” Sunset scratched her chin. She didn’t have anything planned in the human world, and since she was already here… “Can I join you?”

Twily stiffened then yelped “NO!” At the same times as Twilight blurted “YES!”

Sunset quirked an eyebrow, watching curiously as her two friends leaned around her to glare at each other.

“Are you crazy?” Twily whispered fiercely to her twin, as if Sunset was not right in front of her and couldn’t hear everything anyway.

“We asked her if she wanted to participate before, we can’t retract an invitation!” Twilight whispered back, her wings fluffing in agitation.

“What do you think she’s going to do once she finds out?” Twily’s voice became shrill, an onset of panic setting in. “She’s going to hate us!”

“No she won’t, I’m sure of it.” Twilight affirmed, though her tone sounded a little unsure. Her eyes briefly flickered to Sunset’s chest, before she looked back at her twin with renewed confidence. “And we need a control group anyway!”

Twily groaned out loud, pulling on her hair in frustration. “You are just thinking with your peni…”

“Ahem.” Sunset interrupted, clearing her voice loudly. She smirked as both Twilights became flustered, as if remembering she was right there between them. “I can see you need to hash this out, so why don’t we just finish taking our bath then sleep on it.” She turned to Twily, smiling gently to prove that she wasn’t mad that the blushing girl had reserves about Sunset joining them. “Must be something pretty interesting if you want to keep it secret.”

“You could say that.” Twily mumbled cryptically. She gave Twilight a questioning look, the alicorn nodding energetically, then she sighed in acceptance. “Ok, but if we are going to tell you, you have to promise you won’t freak out.”

Sunset frowned a little, wondering what these two nerds were up to, if it warranted so many warnings. “Ok, I promise.” She sat on her knees, leaning closer. “Now tell me, is it something dangerous?”

“Uuuuh…” Twily played with a lock of her long hair, twisting it around her finger. For some reason she brought her other hand to her stomach, holding it there with a worried expression. “You could say it’s dangerous… in a way.”

“Twilight!” Sunset twisted around, glaring at the alicorn. “I hope you two are using protection!”

“Uuuuh…” The alicorn gulped, shrinking back into the water. “Protection? I don’t see what you are…”

“Glasses, lab coats, arcane shields, safety protocols…” Sunset enumerated on her fingers, before throwing her hands up in frustration. “I knew I should have accepted to come with you two. You’re geniuses when it comes to theory but you are always so reckless when it comes to applied research!”

Sunset grumbled to herself some more, the Twilights squirming abashedly. Soon enough, the former pony exhaled, then turned to Twily, a strained smile on her lips.

“I’m in, no discussions.” Sunset held the nerdy girl’s gaze, challenging her to disagree. When Twily didn’t say anything and just nodded, Sunset reached under the water and patted her thighs. Twily squeaked in surprise, but didn’t move back. “I just want to make sure you are safe.” Sunset insisted. “I almost lost my mind thinking I had lost you two, I can’t go home knowing you are really in danger.”

She leveled a harsher glare at Twilight, leaning over to bring her head closer. The alicorn smiled uncomfortably, but Sunset didn’t relent.

“I’m still mad at you for forgetting to write me.” Sunset grumbled. “We’re going to go over your safety measures, and I don’t want to hear a peep.” When the alicorn puffed her cheeks in a pout, Sunset started to reach over again. “I’m just worried Twilight.” She placed her hand over Twilight’s leg, the princess giving a strange gargled squeal from the contact. “I swear I won’t… annoy… you?”

Sunset frowned. She had meant to give Twilight a reassuring nip on the thigh, but her hand had landed on something else. She couldn’t see anything under the layer of bubbles, so she felt around the strange object. It was long and soft, draped over Twilight’s leg like a slumbering snake, but it felt nothing like it. Sunset ran her fingers over its surface, the skin gliding smoothly under her palm, vein-like bumps twitching on her finger-tips. She reached the end of the fleshy tube, her hand closing around its flat, soft tip. Twilight inhaled sharply, her whole body shuddering. Sunset gave the alicorn a questioning look, then started to ask something. The words never left her throat.

Her eyes widened as she felt the thing in her hands throbbing, growing. With each shudder the tip gained width, pushing her hand open, until she had to move her fingers lower, closing them around the tube, just under the widening extremity. The thing kept on growing, beating a steady rhythm against her palm, it almost felt like a… heartbeat. She froze, her fingers clenching unwittingly around it. Veins throbbed angrily under her grasp, pushing even more blood into the rising pole. It was becoming harder and harder with each pulse, the soft and supple shaft stiffening throb after throb. Sunset held her breath as the tip breached the bubbly surface: it was large, deep purple, and completely unmistakable.

Sunset sat there, dumbfounded, as she watched the huge horse cock emerging, her hand still clenched behind the flared head. Before long she could barely close her hand around it, then not at all. Still, she clung to it in her stupor. Finally it stopped growing, the stallionhood still jerking healthily with each heartbeat, as if trying to escape Sunset’s grasp. Her mind was trying to reconcile what she was seeing –and feeling– with reality, what with Twilight being a mare and all. She was stuck trying to convince herself that it was fake, despite the strong heartbeat running through its length, when a warm feeling against her skin shook her off her daze: a warm sticky liquid was leaking from the tip, the clear substance coating the flare, before dripping on her hand.

“Hmm, Sunset?” Twilight gulped, her breath short. “Could you please let go of my penis, please?”

Sunset gave her an incredulous look. “Yours? Really?” Unexpectedly, she leaned closer, inspecting the purple horse cock attentively. “How in the hay did you manage this? How real is it?”

Twilight whimpered. “I… I made a spell inspired by changeling magic, it’s very real.” She shuddered as Sunset’s hot breath washed over her quivering tip, precum now flowing freely down her shaft and onto Sunset’s arm. Not that she seemed to care, too engrossed in her examination.

“Texture, composition, anatomy…” Sunset breathed deeply, the scent of a virile stallion making her eyes flutter. “Wow… Is it functional?” She reached with her free hand under the water, making Twilight yelp as she took hold of her balls, squeezing just a tad forcefully. “Yep, completely functional.” She gave Twilight a cocky grin. “Though you seem to have been a little liberal when it came to size, hmmm?”

Sunset shook her head, rolling her eyes. She guessed she had found the reason for the duo’s embarrassment, and why they had been too busy to write her. This was far from the first cock she had seen, be it human or pony, but she had to admit that Twilight had created a very impressive tool for herself. The stallion scent brought back nostalgic memories, and she found herself inhaling the strong musk greedily, closing her eyes and letting herself go.

Before long she realized that her inquisitive exploration had turned into something more… sensual. She was stroking the purple shaft with one hand, smearing the abundant precum all over it, while her other hand played with Twilight’s plump balls. Sunset could feel them pulsating, expanding, the orbs filling up with seed. Excited stallion scent was now heavy in the air, it was almost intoxicating for the former pony, making her head spin. Sunset jumped slightly when Twily hugged her from behind unexpectedly, her slender arms closing around her torso.

“I’m so glad you’re not mad at us.” Twily whispered softly into her ear. Her lavender hands caressed Sunset’s stomach, breasts pushing against her back. “I was so scared you would think we were… freaks.” Twily buried her nose into Sunset’s fiery hair, hiding her face. “But if you are willing to join us…”

“Oh?” Sunset shivered, Twily’s arm brushing against the underside of her breasts. “Well, maybe I’m not sure about this anymore, maybe I’m still mad at you two.” She squeezed Twilight’s balls, eliciting a startled moan from the alicorn. “Maybe your little experiment is too big for me to handle.” Her hands gripped the purple shaft harder, stopping the flow of precum that ran all over her arm.

Twily hugged her harder, unwilling to let go, then she murmured, “We could start with a trial period.” She placed a hesitant kiss on Sunset’s nape, feeling the older girl shiver at the touch. “Star off slow. Do an alpha test, with kissing and other non committal activities.” Her second kiss was stronger, her lips pulling on Sunset’s skin insistently, her third even more so. “Then we go to the beta stage with intimate touches and maybe actual intercourse, then if things pan out…” She was now leaving small marks on Sunset’s skin, but she didn’t seem to mind at all.

“You are such a nerd.” Sunset’s breath was short, Twily’s hickeys and Twilight’s scent making it hard to keep her head. "This is by far the weirdest way anyone has ever asked me out..." She had to bite on her lips to keep from moaning as the trail of kisses traveled from her neck to her shoulders, Twily even starting to nibble on her skin, like a stallion holding a mare he was taking. “Ok, I’m willing to try.” Sunset grumbled, barely able to maintain her grumpy charade. She looked over her shoulder, finding Twily’s gaze. “But only because you are so cute… *Mmmft*!”

Twily was instantly pressing her lips to hers, cutting her off. The girl’s kiss was passionate, desperate and just a little bit awkward. Sunset was surprised by her intensity, but she wasn’t going to let the meek nerdy girl get the better of her. She responded in kind, taking control over the obviously inexperienced Twily, showing off her skills. Twily’s eyes widened as Sunset’s aggressive kiss pushed her back, a surprised squeal escaping her lips as the older woman slipped her tongue into her mouth. It wrapped around her own tongue, driving it back, wrestling it for dominance. She valiantly tried to fight back, but it was lost cause, and soon enough she surrendered herself to her new lover.

Sunset hummed in satisfaction as she kissed Twily into submission, only relenting once she was sure the younger girl had understood her place. With a loud *Muah* she released her lips, leaving Twily dazed, a string of saliva still connecting their mouths. Sunset grinned cockily; maybe it was her old pony instincts resurfacing, pushing her to establish herself as the alpha mare in this ‘herd’, or she was just simply used to be in control when it came to sex. In any case, she saw this as a competition, one she was intent on winning. She savored her victory for a few moments, but Twilight took her moment of distraction to escape from her grasping hands.

With a snort the alicorn reared up, placing her forehooves on Sunset’s shoulders, her cock exploding from the water. Her hips jerked instinctually as she mounted the kneeling human from the front, her stallionhood jerking around, searching for a place to sink in. Sunset grunted from her the sudden weight, her hands grabbing Twilight around the barrel to throw her off. But before she could push the alicorn away Twily’s hand snaked over her chest, grasping a handful of her tits. The shiver of pleasure made Sunset freeze, giving Twilight the opportunity to slide her cock between her breasts.

Twilight whinnied in satisfaction, gazing down as her stallionhood sunk into Sunset’s cleavage, Twily pressing the mounds together to hold her steady. She pushed her cock further, her legs quivering, until her flared head poked from between them. She held herself there, taking in the sight of her cock leaking all over Sunset’s boobs, her drool adding to the mess below. A low growl startled her from her daydreaming, her gaze flicking to Sunset’s face, and she gulped, a spurt of warm precum escaping her shaft as a thrill of fear ran down her spine.

Sunset was not pleased, and she was going to make sure Twilight knew it. She furrowed her brow, then, with a nasty smirk, grabbed Twilight’s ball none too gently. The alicorn gave a strange strangled cry, but Sunset didn’t let go, her hands only gripping the royal jewels harder. She shivered when Twily started to forcefully cover her neck with hickeys again, but she didn’t relent: these two could work together as they pleased, she wouldn’t give in. She didn’t bat an eye as Twilight begun to thrust between her tits, or when Twily squeezed her tits. She had them by the balls, literally for one of them, they wouldn’t win.

Before long Sunset’s breasts were slick with heady stallion arousal, Twilight’s prick leaking more and more as she enjoyed the titfuck. Sunset had to fight to keep her head clear, every breath bringing a dose of stallion musk to her sense, she could practically taste it in the air. Twilight’s shaft was rock hard, she could feel its veins pulsing against her skin, the alicorn’s plump balls quivering to the beat. Each thrust was accompanied with a chorus of sounds: the slick wet schliks of flesh sliding on skin, the heated gasps and pants, the kisses… Sunset groaned in pleasure when Twily began to tweak her nipples, making her squirm. She had to let go of Twilight’s orbs to protect her tender breasts, but as soon as she was free the alicorn redoubled her thrusting, her hips going wild.

Sunset had to clamp her tits around the stallionhood to keep it steady, least it hit her in the face, and Twily took that opportunity to let her slender hands travel lower. Sunset felt her fingers brushing against her toned belly, tracing the contours of her muscles, then Twily slipped lower still. Sunset let a small moan escape her lips at the first touch, Twily’s fingers caressing her fuzzy pubis carefully, almost shyly. Sunset couldn’t stop her exploration even if she wanted, her own hands occupied with her tits and the horse cock between them.

She had to lean her head back as Twilight loomed over her, the alicorn’s thrusts bringing her flared head just inches from sunset’s lips, spurting precum all over them. The former pony had to use all her remaining self control to keep herself from licking the syrupy nectar from her lips; the smell alone was enough to make her head spin. Twily then found what she was looking for, and gave an experimental touch. Sunset gasped out loud, her clit sending a bolt of bliss up her spine, and Twilight took the occasion to grab her head with magic before thrusting her cock into her open mouth.

Sunset’s eyes rolled back, moaning around her mouthful. Twilight’s musk tasted better than she could have imagined, the scent of a virile stallion overwhelming. Without thought she started to eagerly suck, gulping down the dollops of precum continuously leaking from the flared tip, begging for more with a strangled whinny. Twilight snorted in satisfaction, shuffling closer, looming over her mate, before she begun to thrust again. Twily had to brace Sunset as she was rocked back by the alicorn’s humping, her hands still exploring her fuzzy pubis, teasing her clit while she gently pushed a finger into her slit.

After a few moments of dazed ecstasy, Sunset came to her senses. She tried to pull her head back, but Twilight held her steady, too focused on thrusting into her mouth to notice her struggling. She hummed in protest, but her mouth was quickly filled with precum and she had to keep swallowing. Twilight’s balls were now slapping loudly against eh bottom of her breasts, leaving red marks on her amber skin. Down below Twily was diving deep into her cherry, one hand rubbing her clit while the other gently teased her open. These two had gotten the better of her momentarily, but she was not about to give up control to them.

With a low growl of defiance Sunset hooked an arm around her large breasts, squeezing them together. She reached behind her with her free hand, quickly finding Twily’s little pussy. The duo might have the advantage of numbers, she still had them on experience. She took a long breath, then suddenly started to bob her head up and down, swallowing around her mouthful of pony cock. Twilight whinnied in surprise, trying to pull back, but Sunset just squeezed her tits tighter, keeping her balls deep into her pillowy prison. At the same moment Twily squealed loudly as Sunset pushed her hand against her slit, then sunk her middle finger into her depths. The older woman begun to quickly rub her palm on her clit, stimulating Twily’s love button at the same time as her finger searched for her G spot. A breathless moan later and she knew she had it, her intimate massage becoming faster and more insistent.

In just an instant Sunset had reversed the tables. Twilight was now barely standing on her hind legs, panting like a dog, while Twily was squealing cutely, hugging Sunset’s torso as she tried to hold herself together. Far from letting up Sunset just picked up the pace, her head bobs and rubbing reaching a fevered pitch. She idly wondered who would be the first to go over the edge, and she didn’t have to wait long to find out. With a strident cry Twily’s body tensed, arching like a bow, her breasts pushing against Sunset’s back. Her pussy clamped around Sunset’s hand, but the alpha mare didn’t relent: she pushed her palm against Twily’s hardened clit, her finger tracing circles around her G spot. A breathless moan later and Twily had completely collapsed against Sunset’s back, her hands still hugging her for dear life, orgasmic shivers wracking her limp body.

Now that she had taken care of one Twilight, Sunset could focus on the last. She gently took her hand away from Twily’s quivering honey pot and harshly grasped Twilight’s balls with it. She didn’t stop at Twilight’s high-pitched shriek, her fingers kneading the alicorn’s jewels none too gently. Her rough ball-fondling and her expert sucking quickly pushed Twilight over the edge, her balls jumping into Sunset’s hands as they delivered their payload. Her flare bulged obscenely, pushing against Sunset’s cheeks, eager to spill her seed into her mate. But Sunset had other plans. She smirked, waited for the last moment, then quickly pushed Twilight’s cock away. She twisted to the side, aiming the almost-erupting stalionhood behind her, right at an unsuspecting Twily.

Twilight gave a loud cry of pleasure mingled with frustration, but she was too far gone to do anything but release her load. Sunset felt the royal scepter expand, veins pushing against her breasts, the surge of spunk rushing through Twilight’s shaft making the underside swell. She coaxed the alicorn’s release by licking the edges of her flare, her expert tongue teasing just the right spots, sending the princess into a mind shattering orgasm. Twily blinked, still in a daze, her mouth opening in surprise as she watched the flared head pointed at her. But it was too late to react.

Cum exploded from the alicorn’s cock, the powerful spurt of thick spunk splattering heavily against Twily’s face. The poor girl squealed in surprise, her outcry becoming but a strangled gargle as her mouth was filled with stallion seed. Sunset grinned as she watched the nerdy girl swallow instinctually with a shiver of disgust, spunk dribbling all over her face, clinging to her skin. Sunset watched the bulge slowly going down Twily’s throat, the erotic display sending her loins on fire. But Twilight wasn’t done, Sunset could feel her balls contracting again, still heavy and eager. She did her best to milk her stallion dry, playing with her balls, rubbing her breasts all over her sensitive shaft, and she didn’t stop when the second shot blasted Twily’s head back, or the third, or the following.

Spurt after spurt Twilight came, the pungent smell of her seed completely saturating the bathroom, her cum turning the water a milky white. Twily’s features were positively covered in the stuff, her hair matted with the gooey release, her mouth filled to the brim. At one point the girl had remembered to close her mouth, but she still had a mouth-full of spunk to deal with. She was still working on swallowing it all when the onslaught finally stopped, one last throb sending a thin squirt of spunk on Twily’s nose. Twilight moaned in exhaustion, her stallionhood softening, her hooves quivering on Sunset’s shoulders.

With a grunt, Sunset pushed the alicorn off her, sending Twilight splashing into the clouded water, giving her a taste of her own spunk. She chuckled as the princess sputtered on a cocktail of soap and cum, before turning to the girl still clinging to her back. Twily’s eyes were glued shut, her cheeks still bulging with stallion cream, a look of mild revulsion twisting her cum-glazed face. Sunset felt a little bad for it, but she knew just how to make it up to her. She quickly spun on her knees, disengaging from the hug, then forcefully pressed her lips to Twily’s.

The human gurgled in surprise, then completely melted into the passionate kiss, opening her mouth to welcome her second lover. They shared Twilight’s load, tongues meeting, and they both swallowed together. The former pony moaned into Twily’s mouth, savoring the taste of potent stallion seed, so much more powerful than a human’s. Sunset pushed the meek girl back, her hands grasping her soft breasts in a gentle, but firm, hold. Twily instantly surrendered to the dominant woman, shivering when her back met the edge of the bathtub, Sunset straddling her and sitting on her thighs as she aggressively scooped the last of Twilight’s spunk from her mouth. Still not satisfied, Sunset broke the kiss and began to lick Twily’s face clean, humming in satisfaction at the taste and her success at imposing herself as the alpha mare.

A few licks later and Twily could finally open her eyes again. She watched with bated breath as Sunset loomed over her, the older woman dominating her with her presence and stronger body. Sunset snorted in satisfaction when Twily didn’t challenge her, her old instincts appeased. She smiled gently and gave her mate a quick kiss on the nose, squeezing her soft tits one last time before rising from the water. She waded over to the still gagging alicorn, bubbles of soap and spunk on her lips, then leaned over her. Twilight blinked, then shrunk a little as she saw Sunset overshadowing her.

Sunset grunted and puffed through her nostrils, blowing Twilight’s mane back. Contrary to her human counterpart, the alicorn knew what the display of dominance was about, and she narrowed her eyes. Twilight fluffed her wings, trying to appear bigger, rising to her hooves. Sunset’s brow furrowed at her defiance, her stance widening as she prepared to pounce on her opponent. There could be only one dominant mare in a herd, and she was going to make sure it was her. They held each other’s gazes, but Sunset could see the alicorn already wavering, her eyes darting away submissively before Twilight forced them to meet Sunset’s imperious stare. Tension rose, but before the two equestrians could jump into a biting and bucking match, a high pitched whine distracted them.

“Eeeeek, it’s everywhere!” Twily cried, holding her long hair in dismay. Her long bangs were covered in strands of sticky sludge, turning her hair pearly white. “Oh my god I can still taste it! I need to brush my teeth!” Sunset and Twilight shot each other a look, then they nodded, a temporary truce declared. “Aaaah, my face is covered in saliva! Bacteria! Germs! I can feel the enzymes burning my epidermis!”

Sunset shook her head, wondering what she had gotten herself into with these two dorks. She eyed Twilight rushing to her twin’s aid, the alicorn doing her best to drain the spunky water to replace it with clean one, and she grinned. She followed her new mate, keeping an eye on the package swaying between her hind-legs, her nethers burning in anticipation.

“So, let me get this straight.” Sunset had her eyes closed and was slowly rubbing her temples. “Not only is your experiment about exploring the attraction, both physical and emotional, between parallel dimension twins.” The notion was still giving her a headache. “But you’re also studying the effect of magical semen on a different species, namely if it can impregnate them.” She heard uncomfortable shuffling, then finally two little voices confirmed it. Sunset opened her eyes, shaking her head. “You’re both unbelievable.”

After a thorough scrubbing with lots of shampoo and mouthwash, the little herd had moved from the bathroom to the adjacent bedroom. Sunset was still naked, not seeing the use in putting her clothes back on, but Twily had adorned her lab coat, for some reason; it didn’t cover much at all. Sunset had taken seat on Twilight’s bed, then indicated for the two others to sit in front of her, on the carpeted floor. There had been a moment of tension when Twilight had tried to resist the order, unhappy about Sunset taking control, but a hard stare later and she had lowered her head. Without all the excitement, she didn’t have the confidence to contest the former pony, who was both older and much more experienced at relationships than her. She had sat obediently on her haunches, right beside Twily. Sunset had nodded, glad they didn’t have to come to a fight, then had started to interrogate her new lovers.

“In my defence,” Twily mumbled, fiddling with her fingers. “I asked her to pull out at first...”

“Hey, I told you I lost control!” Twilight pouted in affront. “And you were asking for more after that!”

“That’s because the damage was already done!” Twily countered, starting to blush. “It’s not like I liked the idea or anything!”

“Pfft, right.” Twilight blew a raspberry, then started to imitate Twily’s tone of voice. “Please Twilight, fill my human pussy with more horse cum! Pour your foals into me! Aaaaah, mooore”

“YOU WERE THE ONE THAT ASKED ABOUT HENTAI QUOTES!” Twily shrieked, her face beet red. “I was only demonstrating!”

Sunset couldn’t hold back a chuckle as the two Twilights bickered. She clapped her hands, grabbing their attention. “Okay, new rule.” She marched into the bathroom, then came out with her wallet. “From now on you,” She pointed to Twilight. “are going to use this.” She pulled a roll of condoms from a hidden pocket and tossed it to the alicorn.

Twilight grabbed them in her magic, looking comically dismayed. “But… but what about…”

“No buts.” Sunset crossed her arms, supporting her heavy bust. “If you want to test it we can do it in the lab, with a sperm sample and a donated egg.” She looked at the pouting alicorn with a raised eyebrow. “And if you two want to have foals, if it’s even possible, you can do it once you are sure you are ready.”

“Hmm… I think I’m ready…” Twily murmured, only to shrink back when Sunset shot her a dubious look. “Ok maybe I’m not… Still have to finish my doctorate… Haven’t told my parents…” She gulped. “Oh gosh my family is going to freak out when they find out about us…”

“Not if you say you’re going out with me.” Sunset said with a smirk. Both Twilights looked at her, confused. “Think about it: if you tell your families I’m your mate, they won’t mind it. And if your other worldly twin just happens to be in the same relationship…”

“That could work.” Twilight grumbled. She was looking at the condoms’ tiny labels, her face scrunched in confusion. “Magnum? Flavored? What even are ‘Inches’? No flare dilatation or medial ring ratio?” She clumsily ripped one of the packets open, struggling a little. She examined the bright red rubber, stretching it, before looking down at her sheath, then back up again. “This is way too small, it will never fit.”

“Well yes.” Sunset rolled her eyes, coming closer. “It wouldn’t fit the average stallion, and you made yours even bigger.” Twilight had the good grace of looking sheepish. “Just put a spell on it and make it bigger.” She stopped in front of the alicorn, putting her hands over her hips. “It should do just fine.”

“Eeer, I guess that would work,” Twilight gulped, very much aware that Sunset’s fuzzy pubis was right in front of her face. “but how much do I… Eeep!” Twilight started, her wings shooting open. Sunset was rubbing her sheath with her foot, a huge grin on her lips. “Gnnn… Sunset what are you…”

“Well how else are you going to know how big you need to make them?” Sunset hummed, feeling Twilight’s cock stirring under her sole. She teased the opening of her sheath with her toe, then grabbed Twilight’s horn, cutting off her magic. The condom fell to the floor, but Sunset snatched it out of the air before showing it to a confused princess. “Since you already opened one, it would be a shame to not use it, don’t you think?” She could feel Twilight’s stallionhood already struggling to slip out, but she pressed with her foot, keeping it down. “And I could use some help getting in the mood too.”

Without another word Sunset pulled Twilight closer, using her horn as a handle. The alicorn gulped when her muzzle brushed against the woman’s pubic hair, and she had to choke back a squeak when Sunset pressed her foot down on her balls. The message was clear: service me, or else. Twilight quickly went to work, her tongue slipping out and finding Sunset’s nethers already damp with arousal. As soon as she gave the first hesitant lick, the pressure on her sheath eased, letting her stallionhood emerge a little, the second earning her some more freedom. Sunset even whispered “good girl”, patting her head, her toe dancing on her emerging tip. Before long Twilight was positively slobbering all over Sunset’s slit, eager to receive more praise.

Sunset bit her lips, shivering in pleasure. Twilight was pretty good at this, she obviously had some experience, and she idly wondered with which of her pony friends she had had sex. She let her mind wander, a moan escaping her lips when the alicorn pressed her tongue against her clit, before slipping inside her. Down below, Twilight’s cock was growing harder by the second, her shaft completely free of her sheath. Sunset rubbed her sole all over the lengthy rod, every twitch making her more impatient to have it inside her. She had to strain to keep the powerful stallionhood pressed against the carpet, under her power. It was jerking and bucking, now painfully hard. She smirked, brushed her toes on Twilight’s medial ring on last time, then suddenly removed her foot.

Twilight moaned into Sunset’s pussy, her cock springing back and slapping loudly against her belly, but she still kept servicing her mate. Sunset closed her eyes, enjoying Twilight’s tongue, then a warm body pressed against her side, lips searching hers. Without hesitation she embraced twily and kissed her passionately, the smaller girl throwing her arms around her neck to respond in kind. Their kiss was deep and sensual, Sunset’s hand snaking down Twily’s back to rest on her shapely behind. With a possessive grunt she grabbed a handful of her buttocks, squeezing and pulling the girl closer, her surprised squeak turning into a submissive whimper as Sunset plunged her tongue into her mouth. With one hand holding Twilight’s horn, and the other Twily’s backside, Sunset knew her dominion over them was understood, her alpha mare instincts satisfied

With a gasp she released her lovers, the two Twilights panting slightly, both their lips slick and with her saliva and arousal. She placed her foot on Twilight’s chest, the alicorn showing no resistance at all as she was pushed on her back, her stallionhood jerking against her belly. With a parting squeeze she let Twily go, then kneeled between Twilight’s thighs, gasping her cock in one hand, holding the condom in the other. She gave the alicorn a meaningful glance, Twilight’s horn igniting in understanding. The rubber ring was incased in magic, slowly growing in size.

“More.” Sunset ordered, just a little worried now that she could compare slot A with B. How in the hay had Twily even managed to take this beast? “More.” She couldn’t even get her fingers around it, what the heck. “More.” She was going to have a talk with Twilight after this, this was just silly. “Aaand, stop.” It looked about right, maybe a little snug, but it would do. She took the condom in both hands and in one smooth motion, she had covered Twilight’s flare. The alicorn whimpered a little, but Sunset didn’t stop rolling down the latex ring. “Make it a little longer.” She instructed, only satisfied when she clasped the end behind Twilight’s medial ring, securing it in place.

“It feels weird.” Twilight whined. “Can’t we just do it without, I swear I’ll pull out…”

“Yeah, sure, like I haven’t heard that one before.” Sunset snorted, giving her tip a light flick.

“Hmm, are you sure this will work?” Twily leaned closer, inspecting the stretched latex. “I don’t think the shape is right…”

“I’ll be fine.” Sunset huffed. In truth, she was too horny to stop now. Twilight was covered, it was all that mattered. She wanted Twilight to mount her, and she wanted it now. “Come here.” With a grunt Sunset grabbed Twily, ignoring her surprised yelp, then carried her bridal style over to the bed, shooting an impatient look at the alicorn still splayed on the floor. “You coming?”

Twilight scrambled to her hooves, hurrying after them. She could still taste Sunset’s arousal, and she only had to follow her scent to realize how excited the woman was. Strangely enough Sunset’s musk smelled different from Twily’s. It smelled… almost like a mare in heat. Twilight’s cock throbbed in hunger, the alicorn starting to nip at Sunset’s back to beg her to allow her to mount.

Sunset rolled her eyes, wishing she had her tail to slap the impatient pseudo-stallion on the muzzle. She carefully lowered Twily onto the covers, then climbed on the bed, crawling on top of the smaller girl. She sat on her legs again, her knees on either side of Twily’s hips, savoring the sight. Twily was less buxom than her, but the nerdy girl was still beautiful, her svelte form framed with curves at just the right places. Licking her lips, Sunset ran her hands all over her petite body, before grasping her soft breasts with an appreciative hum.

“I should have asked you out years ago.” Sunset murmured, squeezing gently, playing with her nipples. “Back when you came to Canterlot High.” She leaned closer, her hot breath making Twily shiver as she spoke into her ear. “Have you ever been with another girl?” She asked, grinning when Twily shook her head. “Don’t worry, I’ll teach you.”

Sunset gave her a quick peck on the lips, then swung her body around, positioning her nethers over Twily’s blushing face. Sunset gave her shaved pussy an appreciative look, then dove in without hesitation. Twily moaned in surprise, her back arching, but Sunset didn’t stop, her expert tongue dancing on her hidden love button, coaxing it out of its hood. She kissed her smooth pubis, sucked on her clit, lapped at her slit, anything to keep Twily moaning and squirming under her. Sunset didn’t even care that Twily wasn’t returning the favor, too focused on devouring her lover. So focused in fact, that she didn’t feel the bed shift as the third member of their herd climbed after them.

With an impatient whinny Twilight reared up, mounting her new mate, Sunset’s position on all fours perfect for her. She half expect Sunset to throw her off or worse, kick her, but she was pleasantly surprised. Sunset groaned in approval, raising her ass as an invitation, trying to make it easier for the alicorn to climb on top of her. Panting, Twilight hooked her forelegs around her childbearing hips, hoisting herself into position, her wings fluttering in impatience. A hurried heave later, and her blunt tip finally brushed against her goal. Twilight whined in frustration, the latex covering her cock robbing her of a lot of her sensitivity. She rubbed her stallionhood between Sunset’s thighs, barely feeling her soft pubic hair brushing on her shaft. Deciding she would take as much pleasure as she could despite the condom, the alicorn aligned her cock, then she threw her hips forward.

Twilight’s stallionhood parted Sunset’s folds, beginning to sink inside… and it slipped out, sliding on Sunset’s belly as the alicorn’s hips collided with her rump. Sunset grunted, her frame shacking as she took the brunt of Twilight’s thrust, but she held firm, strong enough to support the alicorn’s weight. She still huffed loudly, warning Twilight to stop playing around an rut her, the princess quickly pulling her hips back. Twilight pressed her tip at Sunset’s entrance, precum squirting inside her condom as she begun to penetrate… and she cried out angrily when her cock slipped out once again. She was about to start thrusting widely in frustration when a soft hand landed on her shaft.

Twily was panting hard, her face flushed, hands shaking slightly as she guided her twin into their new mate. She had front row seats to watch Twilight’s horse cock pressing against Sunset’s pussy, and this time she held it from slipping away. Very gently, she slipped two fingers inside Sunset’s slit, holding her tight tunnel open as Twilight slowly slipped inside. There was some resistance, but finally after a few seconds of struggles the flared head popped into Sunset’s folds, a squirt of feminine arousal dripping on Twily’s lips, her tongue darting out to collect it. Twily savored it with a sensual moan, her nethers burning as Sunset worked on her little pussy, a new orgasm quickly building in her belly. Sunset tasted like heaven, her nectar musky and strong, with a hint of… cherry? She had to try more of it to make sure. Twily gave the shaft above her a couple of taps, trying to tell her twin she was good to go. She squeaked in surprise when Twilight gave a mighty thrust, her stallionhood plunging inside to her medial ring in one go.

Sunset saw stars, pain and pleasure mixing together in one blissful moment as Twilight’s flare rammed against her depths. She heard the alicorn whinnying softly in her ear, her forelegs hugging her sides as she kept her cock hilted. Sunset felt fuller than she had ever been, her walls stretched around the enormous intruder, the latex layer thin enough that she could actually feel Twilight’s heartbeat pulsing through her cock, veins bulging rhythmically. She was then aware of a soft pair of lips exploring her slit, tongue lapping at her stretched folds, brushing against her clit. They were double teaming her again! With a low growl, she dove back into Twily’s nethers, determined to make the girl cum before she did.

Above the two girls locked in a 69, Twilight was in heaven. Despite the condom, she could tell Sunset’s insides were hot and moist, her walls clamping down on her cock. She wasn’t as tight as Twily, but Sunset was much stronger than the smaller girl, her pelvic muscles bearing down on her stallionhood, massaging her length. She enjoyed her rippling walls for a few more moments, before shakily pulling her hips back. Sunset’s tunnel hugged her snuggly, contracting around her flare to keep it inside, making every inch back a delicious torture. The edges of her flare scrapped against her contracting walls, scooping a large amount of feminine juices along the way, an eager mouth rushing to slurp it all as Twilight stopped right at Sunset’s entrance. She hugged her mare tighter, and rammed her cock into Sunset’s honey pot, a large amount of precum sloshing at the tip of her condom as she pressed against her depths.

The trio slipped into a steady rhythm, punctuated by Twilight’s mighty thrusts. After the alicorn hilted she would stay still, enjoying Sunset’s pussy, while Sunset aggressively devoured the girl under her, Twily squirming on her back and giving high pitched moans. Then Twilight would start to pull back, slowly, her withdrawal seeming to last forever, Sunset tensing from the pleasure while Twily worked her slit, eagerly waiting for the inevitable squirts of feminine arousal. Once only her tip was still inside, Twilight waited for a random period of time, letting Sunset become mad with anticipation, then she rammed back inside. The cycle continued, the slaps of flesh against flesh and muffled cries echoing around the castle.

Sunset had no idea how long they had been mating for, but she could feel her strength fading. She came a few times already by this point, and she could feel a stronger orgasm approaching, building in her stomach. She wouldn’t last long anymore, but she took solace in the fact that Twily had come a lot more than her, the poor girl already too far gone to do anything but twitch when Sunset playfully teased her engorged clit, Twily’s tongue occasionally darting out to lick her lips, feminine juices continuously dripping on her dazed face. Sunset was rocked by another thrust, Twilight panting into her fiery hair, her ragged breath tickling her neck. This time the alicorn didn’t stop to enjoy her velvety insides, her hips drawing back instantly before slapping back against Sunset’s rear without waiting to reach the entrance of her tunnel.

The frantic humping almost threw Sunset off balance, but she braced herself, afraid to hurt Twily, still passed out under them. She could tell Twilight was close, her balls heavy and plump as they slapped on her belly with every thrust, her flare growing inside her. A little afraid for the state of the condom, Sunset started to wiggle her hips, trying to make Twilight finish before she ripped it apart with her wild humping. She yelped in surprise and a little bit of pain when the alicorn suddenly bit her nape, her muzzle buried in her hair. Twilight growled like a feral stallion as she held her mare steady, her thrusts becoming even more urgent and wild. The bestial way she was taken was the last straw for Sunset, the biting sending a rush of pleasure through her body.

She whinnied loudly, cumming like never before. Her whole body shook under the waves of her orgasm, robbing her of her strength. She almost collapsed, but Twilight wasn’t done with her, the alicorn holding her in place as she took her savagely, hips slapping against her shapely behind, leaving red marks where they met. Her flare now obscenely large, straining against the overstretched condom, Twilight pounded into her mare a few last times, ready to spill her seed. Jostled by the frenzied mating, Twily came to her senses just in time to see her Twin ramming her cock into Sunset one last time, holding herself hilted. Twily reached for the purple balls hanging just above her, feeling with awe as they expanded in her grasp, ready to deliver their load.

Twilight snorted, biting just a little harder to make sure her new mate wasn’t going anywhere, then she let herself go. Twily’s eyes widened as the purple orbs contracted, she could actually feel the flow of semen rushing from them, the underside of Twilight’s shaft bulging with it. Sunset felt the surge coming, and she gave a silent prayer to Celestia, hoping the rubber was still whole.

Sunset pupils shrank to pinpricks when she felt warmth spreading through her depths, but she quickly realized she couldn’t actually feel the onslaught of semen. Twilight whined angrily as her thick release was trapped by the sturdy condom, her balls producing more and more in her frustration. Sunset breathed a sigh of relief, thanking Celestia and the almighty Trojan, relaxing. She was still riding the aftershocks of her orgasms, and was content to just wait for Twilight to stop cumming.

Only Twilight didn’t seem to want to stop. After a few spurts, the condom’s tip was already filled, but Twilight just kept on cumming and by the time Sunset realized something was wrong, the latex was ballooning out, stretched taunt and ready to burst. Sunset could actually feel the condom bulging against her walls, and before long Twilight’s had to fight against her own release to keep herself hilted. The alicorn snorted angrily as her cock was slowly pushed back by the amount of cum she was packing tightly in Sunset’s depths. Twily saw her shaft bending with effort, still spasming with new surges of spunk, her hands massaging Twilight’s balls, unwittingly helping her produce more and more semen.

Then, with a mighty growl of defiance, Twilight rammed her hips against the mass of thick spunk, releasing a new desperate burst. The condom held, but just when Sunset thought she was safe, a strange sensation made her heart drop. After being squeezed so tightly, the latex membrane had nowhere to escape… except the small opening of her womb. Sunset felt it worming its way into her cervix, the pressure pushing the condom’s tip deeper inside. In her panic Sunset contracted her muscles, trying to push it out, but she only succeeded in pinching the already overly stretched membrane. Her blood ran cold when she heard a distinctive ripping sound: the tip of the condom had given out, the pressurized pints of semen rushing into the opening.

Sunset was too tired to throw the clingy alicorn off her back, and could do nothing as a geyser of magical pony semen flooded her womb. The broken condom was acting like a funnel for the mass of thick pressurized seed, Twilight’s flared head squeezing it all into the tight opening like a piston. Twily held her breath as she watched Twilight’s cock slowly sinking back to the hilt, not one drop of spunk escaping Sunset’s depths. Before long she could see a bulge forming on Sunset’s stomach, stretching her skin taunt, and she didn’t have to wonder long to realize what it was. She had felt Twilight filling her own womb less than an hour ago.

With a satisfied grunt, Twilight finally managed to press her flare against Sunset’s cervix, pushing everything inside. A quick tug later and the condom’s tip slipped out, letting her womb seal itself with Twilight’s precious load inside. She gave her new broodmare one last playful thrust, making her inflated belly jiggle, then finally withdrew her still hard shaft. Sunset collapsed on her side, still mindful of Twily, her hands feeling around the bulge in her stomach. A million thoughts passed through her head, but she was too exhausted to dwell on them. She just rolled on her back, trying to get her breath back.

“Wow…” She murmured, panting.

“Yeah,” Twily sighed, crawling until she was lying next to her. “Twilight can get a little heated.” She rested on her elbows, watching Sunset’s chest rise and fall, sweat running all over her golden skin. “I guess it’s a pony thing?”

“No, that’s a Twilight thing.” Sunset groaned, already feeling the aching in her hips. “I’ll put her back in her place…. After I sleep this off.”

“Sleep?” Twily arched an eyebrow. “I wouldn’t bet on that.”

Before Sunset could ask what she meant, the two of them where encased in a nimbus of crimson magic. She was dragged to the edge of the bed, while Twily was levitated and gently deposited over her. Sunset felt her feet hit the carpeted floor, her ass placed just on the edge of the bed. She looked into Twily’s shifty eyes, the girl resting belly to belly on top of her.

“Yeah, I probably should have warned you, but…” Twily squeaked when something heavy landed on her ass, pressing her bare nethers to Sunset’s fuzzy pubis. She smiled apologetically. “Twilight can go multiple times in a row.”

“How many times?” Sunset grunted, trapped under the weight of both Twilights. She could see Twilight’s wings out of the corner of her eyes, behind Twily, the alicorn mounting them both at the same time. “I don’t think I can take much more…”

“Hmmm, well…” Twily paused as they both gazed at the graceful arch of the broken condom as it flew over their heads, before landing perfectly in a trash-bin on the other side of the bed. “I kinda lost count last time…” She grinned shippishly.

“Great…” Sunset huffed. She felt Twilight’s cock brushing against her pussy, before it arched up towards Twily, then it settled between them, as if hesitating. “I guess if I have foals with Twilight at least I’ll have an excuse to stop avoiding Equestria.” She smirked a little. “Thought I know someone that might be a just little bit peeved when I show up with a baby bump, particularly when I tell her who’s the ‘father’.”

“Oh, who’s…” Twily gasped might sentence, her eyes widening. Twilight had obviously chosen which one of them to fuck first. Twily was quickly rocked forwards, loud slaps echoing around the room. “who’s… who’s that?” Twily valiantly managed to ask between pants.

“My mother.” Sunset smirked.

She preempted Twily’s follow up question by pressing her lips to hers, in a move she was becoming very familiar with, and they were instantly writhing together, their limbs intertwined as a horny alicorn railed them. Twilight felt a great deal of primal satisfaction at having her two mates sandwiched under her, and she quickly switched from Twily to Sunset, her cock slipping from the tight confines of her twin only to plunge messily into the muscular depths of her old friend. Without that darn condom she could finally enjoy Sunset’s velvety walls fully, and it didn’t take long for her to build a new release.

She grunted in satisfaction as she hilted into Sunset’s depths and spilled her seed properly, the stuff pooling in her pussy, before she pressed her tip against her cervix and forced a new batch of virile spunk into her fertile womb. After only a few spurts she threw her hips back, firing ropes after ropes all over Sunset’s tunnel, turning it into a slimy mess. Her stallionhood burst out of Sunset’s pussy with a deluge of spunk, the alicorn spurting all over her lovers backsides. Twilight then forced her cock between their bellies, making sure they were coated with a healthy dose of her scent, her large shaft rubbing on both Twily’s and Sunset’s clits.

Twilight could feel Sunset’s bulging belly pushing against her flare, and her cock erupted with new energy when she imagined Sunset as an expecting mother already. A mother to her foals. She grabbed Twily harder and forced her spewing shaft into her twin’s tight slit. One vigorous thrust later, and Twily’s womb was filled once again.

Twilight grinned, knowing deep in her heart that she had impregnated them both today. Before long they would be sporting round bellies, each of them with a foal or two, and once her children were born, she would take them again and again. Maybe it was her alicorn magic, or just animal instincts, she just knew. But still, she kept on pumping more into her twin, before switching again, Sunset moaning in protest as her already filled belly grew even bigger. Twilight didn’t stop, focused on breeding her mates.

The castle echoed with the sounds of love and lust for the rest of the night, breaking its usual silence.

Maybe nights would never be lonely or silent again in the castle, be it because of the cries of passion, or the laughter of an army of future little foals.
