Chapter 3: Not Such a Shy Mare Now

Following where he believed he heard she went to and where her voice came from. Zakia found he was now in Fluttershy's bedroom, he overshot the bathroom she scuttled off to. The large bed looked comfy and soft. But Zakia couldn't see the mare in question. The sudden shove against his back, landing him on the bed answered his question. Turning around didn't serve too well, Fluttershy was at the edge of the bed, her clothes were gone, letting her surprisingly massive boobs hang over the bed, swaying with her every breath. Her body was shivering like she was aching for something, and her face was panting and covered in a thick blush of red and lust.

As the mare wiggled herself, her massive dildo slid out of her, slowly and tantalizing as it seemed her pussy was doing everything it could to keep it in. It was impressive in size, as it reached flare. It stuck there for a moment as she squirmed a bit more violently causing it to plop out of her pussy, leaving only a trail of wetness down her thighs when it dropped to the ground. The wet smacking sound echoed almost as it hit the ground. Zakia only internally laughed at how big such a toy was, but was impressed with how much this shy mare could take. He had to admit, he didn’t think such a timid mare would have such a massive toy. For a moment, he even thought it was ironic how it was as if she was preparing herself for his own sizes.

"I'm so sorry but I need you, I don't know why but my body needs it... I need it" Fluttershy explained, leaning back, standing up and showing off her wet and aroused body. "Please help me with this, Your scent is so heavy and I need this. Your musk it's j-j-just, it's just so hot...so sexy...I can't stop myself. Please, just give me your cock. My wet pussy needs to be filled. Please." She was begging for it, right off the bat. He liked this, but it also took a bit of the fun out of it.

Zakia didn't let this ruin it for him, he was pleased at the results regardless and smiled at how quickly the potion worked. Maybe a little too quickly. Given how Fluttershy was shy and went straight to sex crazed slut, maybe the dosage was too high. He'd speak with Zecora about it later though. For now, Zakia was going to enjoy his prize. Getting up, Zakia fidgeted at his cuff gems, causing his clothing to vanish, leaving his body naked and bare for Fluttershy's amusement. His twin cocks were already semi-hard, bobbing up and down a little. Fluttershy’s eyes never left the bobbing erections. She was in a complete cock-trance, licking her lips without meaning to. Zakia decided to tease the horny Pegasus, grabbing hold of one of his lengths and shaking it, startling the dazed and newly blooming bimbo from her vacuous stare. Fluttershy blinked innocently as she slowly pieced her thoughts back together. She eventually settled on the bed, her face now staring directly at Zakia’s, who was now standing, twin cocks.

“So big,” Fluttershy chirped while taking Zakia’s two swollen and gargantuan oversized balls in her hands and beginning a slow, sensuous massage. “You got sooo hard for me... and you’re getting harder... so... very... hard...” She was using that singsong, compelling voice of hers, vibrating her words right into Zakia’s head, body, and most importantly, his overly aroused cocks.

One of Zakia’s cocks began to bounce in the air, pulsing rhythmically with each heartbeat, the veins thickening visibly with each pulse. Zakia let out a small groan as Fluttershy continued fondling his shaft, while keeping the sensual massage she started on his balls. Her feathers tickled at Zakia’s thighs, on his legs, and against the smooth, white fur of his loins and heavy balls. Fluttershy slowly pulled Zakia down with her pillowy chest and perky nipples dragging against his side. Her wide hips wiggled back and forth, her large bubbly butt arched up behind her so that Zakia was treated to a view of her jiggling ass-cleavage. The silky texture of her mane splayed across the small of her arched back as Zakia sat back and watched, allowing her ministrations to bring him to a state of incredible sexual arousal brought on by her lewd dancing and erotic, purring noise.

Her lips slowly descended towards Zakia’s tip before stopping a hair's breadth away. They slowly opened, spreading apart as she exhaled hot breaths of air over his twitching cock. Fluttershy smiled, a surprisingly cunning glint shone in her eyes while she glanced back up at her soon to be zebra master. The entire time, her hands had been continuing their stroking of Zakia’s length, stirring the bubbling cauldron of his cum past boiling in his tightening balls. She breathily exhaled on Zakia’s cock, whispering to herself as she stared longingly.

“So hard... so hot... so full... so ready for sex! You’re going to fuck me so hard. You’re going to mount this pussy again and again.” Fluttershy whispered in a heavy and heated sultry tone, her eyes fixed on every thick inch of Zakia’s cock. “It’ll make your dick feel so good you won’t want to pull out, not even after you’ve cum. You'll want to be in me all the time, your flare holding me as it splays open my womb” It was clear that at this point Fluttershy from before was long gone, now all that was before Zakia was a sex crazed whore that wanted his dick. The potion was clearly far stronger than he expected, he didn't think it would be so effective.

Zakia shuddered a little as her words took effect. Fluttershy was being focused now, driven by her determination to have Zakia fuck her eager, sopping wet, beautiful and juicy mare pussy. Zakia couldn’t wait anymore; it was time to take control of his new slut. She was trying to take the lead and she had for a few moments... he wasn't gonna allow that. She was gonna learn her place as a zebra's slut, not a whore that can boss a zebra around and get dick whenever she wants. Grabbing hold of Fluttershy’s head, he pushed her down over each of his cockheads, surrounding himself with the soft pleasure of Fluttershy’s plump, tingling lips. Her plush lips suckled into a vacuum-tight seal around Zakia as he crudely began to face fuck the not so shy mare; soaking and lubricating his girth with Fluttershy’s warm and slick saliva.

Fluttershy offered no resistance, only moaned as she took inch after inch with each bob of her head. She wanted Zakia to fuck her throat as if it were her cunt. It only made her body shiver, and her pussy quiver for its turn.The musky air Fluttershy inhaled was utterly saturated with the scent of Zakia’s maleness and was heavily laced with virile pheromones, making her pussy drip like a loosened faucet. Fluttershy’s mouth felt good, but the dripping on her leg reminded Zakia that there was a juicy pussy just waiting to be filled. Fluttershy’s mouth was a decent first course for her creamy pussy, but Zakia wanted the real fun to begin. Zakia forced her off, the mare’s plush, cock-sucking lips still connected to him by a shimmering wet line of drool dangled from her mouth.

“Fuck me, Zakia. Fuck me, super hard! So hard I can't walk or even fly!” Fluttershy panted, her face too flushed and aroused to think of anything but her need to fuck. Zakia halted his actions and looked at her with a stern face "I'll fuck you when I'm ready slut, you'll also address me properly you loose pony whore... you call me, Master. You're a cock sleeve born for my pleasure, remember that whore. If you don't understand that I won't be touching that dainty pussy at all. '' Fluttershy mewled with a sense of fear and understanding. Her eyes held a great fear in them at his words, they cut to her core... she couldn't have that. "I'm sorry Master... please forgive this pony slut." Zakia was pleased with her response and nodded, with that her cheerful bimbo attitude returned.

Fluttershy tried to crawl around on all fours, her swollen breasts dragging across Zakia’s lower body as she turned. As soon as her ass shifted towards Zakia, his eyes widened. Her heart-shaped ass was so curvy, so perky, and delightfully soft that Zakia couldn’t resist his body’s impulses. It was hard to believe, but Fluttershy’s sexy body was calling to every fiber of Zakia’s being. He HAD to fuck her! Fluttershy’s fur thighs were soft and shivered at his touch. She was like a chunk of sexual clay in his hands. This not so shy mare was eager to please Zakia, and he intended to explore every possible pleasure he could take from this new slut.

Zakia was up in an instant, pushing Fluttershy over. Zakia’s cock pressed hard against Fluttershy’s soft and wet mound, he felt her mare cunt wink as it pressed against her impatient pussy, the rest of his saliva coated cocks slipped between the soft, lubricated ass. Her tail laid across Zakia’s chest in a pink silk softness. Zakia smirked at the angle he was at, he could fully watch his length slowly slip into Fluttershy’s pussy lips, smeared with another layer of Fluttershy’s mare juices. Zakia was feeling an immense feeling of arousal from teasing Fluttershy alone, but the thick scent of her sex left from the face-fucking began to do their work. Zakia’s nostrils flared as he felt himself getting harder from the scent alone. Looking down, Zakia only smirked; it was time to fuck this slut.

The impact of Zakia’s wide thighs slapped hard against Fluttershy’s smooth, round ass caused the mare to bounce forward in a hard motion; Zakia’s body pulled back, only to slam back repeatedly. Zakia grabbed at Fluttershy’s hips, keeping up the pace of his thrusts with reckless abandon; digging his fingers hard against her soft flesh as he fucked her. Fluttershy’s sobbing, wet pussy lips greedily took in Zakia’s length, pulling in more and more of his cock like a glutton. Though shy not long ago, Fluttershy was now bouncing her ass back against Zakia’s cock. Her pussy became tighter and wetter to feel her new zebra master’s cock buried itself deeper into her needy snatch.

“Fuck me, Zakia! Fuck my horny...oh yesss...pony cunt! Mmmmm... gimme...gimme your cum!” Fluttershy cried out in her repeated passion. Fluttershy’s mouth hung open in a broken, fucked silly expression as she felt orgasm after orgasm hammer through her body as she screamed for more. “Gonna make me a mommy, Zakia, a pregnant, cum starved... oooohhh...momma!”

Zakia wasn’t too keen on impregnating Fluttershy, at least not yet, but her erotic body was making it hard to resist the urge; which didn’t stop his cocks from getting harder. His hands found their way to just above the curve of her waist and began to pull the slut mare down with each motion forward he was making, forcing her to meet Zakia halfway. Zakia was soon pounding at Fluttershy’s desperate and fucked broken cunt like a wild beast, juices squirting out with each booty-shaking cunt-stuffing thrust he slammed into her. Zakia’s cock felt like it was being crushed by Fluttershy’s soft, moist, and tight pussy. Her inner walls clamped down with a firm yet soft grip, begging him to keep going. Fluttershy came repeatedly around Zakia’s cocks, wiggling her ass in a circular motion between each orgasm to drive Zakia on. Fluttershy’s motions paid off, her pussy was clamping down and sucking in Zakia’s cock every time he tried to pull out.

Every ounce of strength in Zakia’s body shifted to stuffing his dominating cock as far into Fluttershy’s pussy as possible, ramming so hard into her that the broken slut mare was screaming in a mix of pain and pleasure, as his flare smashed right past her cervix and he started battering her womb with a relentless and brutal force. Zakia’s dicks swelled with the onset of his release, and his two swollen and oversized balls began to rhythmically pulse, constricting together as their bubbling load sloshed around. Fluttershy’s pussy stretched around Zakia’s increasing thickness, dripping its sweet nectar over his extra, thigh slapping cock. The warm ecstasy inside Zakia rushed out in a tremendous spurt, squirting globs of thick white cum into Fluttershy's womb again and again. Her womb quickly reached its current limit and started pushing out the excess cum. Ropes of creamy spunk drizzled over the ground and on the underside of Fluttershy’s large boobs, but the lust-drunk Pegasus didn’t seem to mind any more than Zakia did. In fact, she reveled in the warm feeling coating her body and filling her insides.

Fluttershy’s hungry twat drank down Zakia’s cum with gusto, milking the swollen cock for everything it had. Zakia’s lips curled into a wicked smile of satisfaction at how his cock felt as though Fluttershy's very pussy walls were gripping at him. He was impressed that someone other than Zecora could manage such control and pressure, or at least enough to make him feel it. He never would have expected this once timid mare was also a talented whore. She would serve him well. It was a sign she had great potential, and how her cunt was made for the purpose of drowning in cum. So, Zakia gave her what she wanted, drowning her pussy with cum. White spunk trickled out of her lips after Zakia stuffed her womb full, dripping down his legs.

As Zakia’s orgasm died down, Fluttershy slipped forward, her eyes rolled back and her body twitching slightly from the afterglow. Zakia sighed, partially satisfied, but one of his dicks was still erect, still tingling, hungry for pony holes. Fluttershy’s asshole winked as her orgasmic contractions coursed through her body, and as Zakia watched, he knew he would have to sample her backside before he would give her to the Siri or maybe even her own animals. With how much her cunt was still begging for cum, she might be useful as a cum soaked broodmare. But that was a thought for another time, Zakia still had much more to do. Pulling himself out, Zakia’s cock plopped out with an audible popping sound. Though the moment Zakia pulled out, Fluttershy instantly turned to stare at him.

“Noooo please don't stop master! Please fuck me again! Keep breeding me, keep filling me with your cum... I feel so empty already and it doesn't feel right without you in me!” Fluttershy shuddered, confused eyes looking back at Zakia. “I still want to be stuffed with your cock!” Zakia blinked a little, still a little confused over how easy this was, shrugging his shoulders, he continued his conquest.

Zakia shifted position slightly, grabbing at Fluttershy's wide ass for leverage, allowing Zakia’s fingers to sink into its supple flesh, giving in to his fingers as he pulled her cheeks apart; mapping the perfect path to her eager pucker. Zakia pushed his unused cock against her backdoor immediately. There was a moment of resistance, but Fluttershy soon relaxed, and all the spunk, mare-lube, and slippery substances covering his cock helped him to slide into her yielding ass with ease. Fluttershy’s ass was far tighter than Zakia had imagined, it was firmer than her pussy but far more challenging. But as Zakia rammed his cock further into Fluttershy’s asshole, he had overlooked something. His other, recently spent cock was not only hardened with renewed vigor, but was still lined up to Fluttershy’s pussy. When he rammed himself into Fluttershy’s ass, his other cock had rammed back into the slut mare’s pussy.

“Fuck! it's so deep, it's stretching me so wide!" Fluttershy moaned, the pleasure and pain of being double penetrated was striking her mind all at once. “I didn’t want it in my ass, just my slutty pussy!”

Zakia, though enjoying his time with his new pet, was not one to take any form of back talk. Raising his hand, Zakia groped at Fluttershy’s ass hard, making the cheek red and sensitive from his strong grip. The moaning mare would soon learn her place. With his position better established, Zakia began to properly reem Fluttershy’s ass and pussy with greater strength. Fluttershy was able to get Zakia this horny, and he was going to fill her every hole, and she was going to scream for more. Fluttershy’s asshole was tight, almost too tight after having experienced her pussy, and Zakia could feel his next batch of cum already beginning to churn in his two swelling balls, a heavy, warm weight grew larger.

Fluttershy’s sexy rump felt amazing, but Zakia was getting tired of doing all the work. He let go of her plump buttcheeks and wrapped his arms around her torso, just under her tits and leaned back, pulling the soft-bodied bimbo mare up on top of his as he reclined backwards. Fluttershy’s weight caused her bottom to squish against Zakia’s cocks, enveloping his shafts in smooth and wet folds. The curvaceous pony gave no words or any sign of resistance. She only continued to grind her hips against Zakia. Was it the potion that did this, or was she always this good? Fluttershy immediately began to bounce on top of Zakia, her tight asshole clenching as she lifted up and drags her bountiful butt off him. His lube-coated poles were revealed briefly to the air before they were devoured by the hot, enveloping anal entrance and squeezing pussy all over again.

“Is this good for you, Master Zakia?” Fluttershy groaned, while looking back over her shoulder. Her eyes sparkled, looking for approval from her zebra master. “Are my holes making your cocks feel good?”

Zakia answered by sitting up and groping at her tits, nipping at her shoulder at his silent yes. Fluttershy’s breasts felt softer than her pillow-like ass cheeks, which even now were smashingly running over his hips and legs, smothering him in soft warmth while her fuck canals continued to milk his thick shafts. Zakia roughly squeezed Fluttershy’s breasts, too focused on the climax slowly building within his compressed crotches to be gentle. Fluttershy’s breasts bounced and jiggled around Zakia’s grabbing; her nipples, hard as lead, were like magnets for Zakia’s eager fingertips, and soon he locked onto them, squeezing and tugging, kneading them with each bounce for encouragement. Fluttershy screeched as she bottomed out, pushing herself back against Zakia, noisily cumming; her juices running down his flat-tipped horse-member in miniature rivers. The explosion of sloppy mare juices accompanied by anal clenching, and with a hard pinch on her nipples, Zakia let out a few more ropes of cum deep in Fluttershy’s wet cunt, and tight ass canal.

Cum flowed into Fluttershy’s ass like a white stream, squirting into every nook and cranny. Zakia hugged Fluttershy's body as hard as he could, both hands locked in place, keeping Fluttershy’s ass planted firmly against her cocks. Fluttershy wrapped her arms behind herself, holding onto Zakia affectionately. Again and again, Zakia grunted as he blasted rope after rope of spunk into her soft rear. At the same time, he was making her cunt even creamier and her belly even more bloated. There was no stopping Zakia’s orgasm. He was going to continuously cum until there was nothing left. Fluttershy’s belly rumbled a little as Zakia filled more and more of her insides, eventually adding to her visible inflation. Zakia had now filled every inch of Fluttershy with his warm cum, and there was simply nowhere for his squirts to go but out; trickling like little rivers from around his swollen shafts.

Fluttershy went limp in Zakia’s arms, cum still dripping from her cunt as he continued to sate himself on her rear and hard nipples. Pulling himself free of her warm and used up holes, Zakia wasted no time. In a swift motion, the still aroused zebra turned Fluttershy around, grabbing at her face and pulled her down on each of his cocks again; ramming them into her throat without warning. Fluttershy gave a muffled grunt of displeasure before suckling on it again, just as enthusiastically as the last time. Her tits dragged over Zakia’s legs as she began to bob on her own, prepping him for the revisiting of her warm, cum soaked pussy.

“Just one more, in my pussy, please? Please, cum in my pussy again!” Fluttershy begged, licking her lips from the small drink of cum. “I know you must have more in your delicious orbs.” Fluttershy couldn’t help but give each of Zakia’s balls a tender kiss each as she moaned.

Zakia shrugged his shoulders playfully, deciding to give this slut mare what she wanted. In yet another swift motion, Zakia pushed Fluttershy’s mouth off his cocks and lifted her over him, letting the mare slam hard against his cocks. Fluttershy shivered wildly, almost to the point of thrashing as she felt her cum stuffed fuck hole be filled again. Fluttershy immediately began to bounce it up and down, looking down to watch Zakia’s face as the waves of sensation overpower him. Zakia was amazed at how easily his twin cocks slid into Fluttershy’s hot cunt. With how her tongue dangled out from the side of her mouth as she rode, she didn’t care that one, two, or if even ten cocks were inside her pussy at once, all that mattered in her mind was a constant need to breed and fuck.

‘This mare’s pussy is too much.’ Zakia thought, realizing he was running out of energy faster than he thought. ‘Was this pony always this beastial in bed, or is this the potion? And with how well she takes both my cocks at once, her potential is too great to pass up.’

"This feels amazing!" Fluttershy continued riding Zakia's cock with reckless abandon for any form of decency. "Fill me with more cum, I want it all, I never want this amazing cock out of my cunt ever!"

"Really?" Zakia teased, grabbing at Fluttershy's hips, driving himself deeper into Fluttershy's hole. "What would you do for my cocks inside you? To feel them both grinding inside your naughty cunt like the whore you are?"

"Anything!" Fluttershy cried out. "I want these cocks inside me, I want this cock every day, no matter where, I will fuck these cocks!"

"You will become my personal slut, you will be a cumdump for me and anyone else I deem worthy. You will become nothing more than a broodmare, used for my pleasure and anyone or thing I say you are to please." Zakia stated, pressing the tips of his cocks against Fluttershy's womb. "You will embrace me as your master, be my sex slave, always eager and willing cunt to take my cum."

"Yes!" Fluttershy didn't even take time to think. "I don't care about anything else, I'll fuck anything you want! Ponies, dogs, dragons, animals; I'll even be fucked by the entire royal guard, just give me your cum. I don't care what happens to me or what you want me to do, I'll serve you always and forever."

"Good slut." Zakia responded, leaning up enough to try and whisper in Fluttershy's tingling ear. "You've earned every drop of this."

Zakia soon came promptly, squirting a long rope of pleasure in and on top of all the sperm he already deposited. Fluttershy bounced, forcing more of that ecstasy through his monstrously thick cocks, laboring messily atop Zakia in a lascivious display. Every upstroke of her silky warm walls along Zakia’s shaft earned her all the cum his balls could offer up since the last downstroke, weak spurts of little bearing, but still an extra dose of spunk for her twat. Zakia fell back, eyes rolling wildly, moaning uncontrollably. His consciousness became little more than the feelings tingling through his thick, flat-tipped horse-member and the ensuing orgasms. Despite how skilled the zebra stallion was, Zakia lost track of time and passed out; he was not defeated, but he had met his match.

When Zakia finally awoke, Fluttershy was snuggled up next to him, her arms and legs wrapped around him affectionately. A cup full of water, along with several strips of dried vegetables sat nearby...apparently she got them while he was out, knowing how thirsty and hungry he’d be. What else was interesting, was Zakia didn't feel any dried cum on his cock and stomach. Was it possible that while getting food, Fluttershy cleaned off his body and junk? Tilting his head to look out the window, Zakia could see it was possibly the late afternoon. Was he asleep all day? Fluttershy’s body was still covered in dried sweat and bodily fluids, and her belly still felt a bit bloated as it pressed against his body. As he tried to free himself from the Pegasus’s hold, he heard her stir.

"Mhmm hello master." Fluttershy cooed, nuzzling herself against Zakia's body. "Did you sleep well?"

"Well enough." Zakia responded, fully sitting up. His hands gently caressed Fluttershy's chin, much to the delightful purring of the pony. "How does my new cumdump feel?"

"Just perfect master." Fluttershy replied with a warm smile. "When can you feed your eager slut your honeyed cock nectar?"

"Serve me well, and I'll feed you with all the cum you want." Zakia replied, patting her on the head. "For now, you will follow every order, understand?"

"I listen and obey." Fluttershy hugged Zakia affectionately. "I'll do anything you want for your cocks and their cockmilk."

"Perfect." Zakia commented, his eyes gleaming with a dominant glow. "You are to go about your life as you always have, but when I call on you, no matter where you are, you are to obey and do as I say. Understand?"

"Yes master." Fluttershy smiled, gently rubbing at Zakia's limp cocks. "But can we have another round?"

"No." Zakia said, getting up from the bed; with a simple gesture of his brace cuffs, he was back in the attire he was in earlier. "In between your other tasks and duties, I want you to train your body. I want you to always be ready for cocks to be inside you."

"But what will I do in the meantime?" Fluttershy asked, wiggling her body in need of more sex. "What if my slutty body can't wait for more warm cum from you?"

"Don't worry." Zakia reached into his pockets, pulling out a small scroll. "You are to follow these instructions. They contain what you are to do, some new piercings that will attach themselves when they are in place, it will hurt for a moment but you'll be brought greater pleasure with them. You will be wearing these under your normal clothing, and of course, you will be servicing not only myself, but my other servants, and anyone else I want you to fuck."

"My pussy just came a little master." Fluttershy shivered, a small puddle of her mare juices, and Zakia's cum came under her and between her legs. "I can't wait master, I'll fuck anyone you want, but I'll always want your hot cock in my whore cunt!" With Fluttershy's nodding confirming Zakia's plan was a success, Zakia took his leave.

Leaving the cottage, Zakia looked around to see the beautiful arrangement of color that the sunset was. The array of light and color brought a moment of peace within the zebra. Fluttershy's conversion to his cause didn't go as perfectly to plan as he wanted, but he gained an eager and seemingly loyal cumdump. So if he didn't get any practical or personal use from her, Fluttershy would serve as a cumdump for other zebras and ponies. Maybe even sell tickets to see Fluttershy breed with some large beasts from back home for entertainment.

Walking out of the house, Zakia raised his hand and then pointed to a nearby tree and then a bush. Instantly, a muscular zebra stallion dropped from the tree while another stood up from the bushes. Zakia was a mix of impressed, and yet disappointment. He was impressed that his Siri were as active and dedicated as he had instructed, but he was still disappointed because of how poor they were hiding, they must be rookies compared to the rest of their squad. But Zakia chose to let this go, he had plans for these agents. Gesturing to the two zebras over, Zakia thought of a good use of these Siri agents. The two zebras said nothing, only silently obeying their master.

"I want you two to keep this one occupied." Zakia ordered. "This mare is not to be underestimated and you are to do as she says. Treat her demands as if they were my own, until she is satisfied." Both Siri simply nodded and turned back towards Fluttershy's cottage.

The moment the Siri entered the cottage, their ears were struck by the sultry moans of Fluttershy's voice. Smirking at what a reward the two were about to receive, both Siri dropped their serious expressions; including their clothes, stripping down to their bare bodies in a matter of moments. As the two walked further and further into the cottage, walking towards Fluttershy's room, both the Siri's cocks grew with arousal, their shining cock piercings only bobbed a little with their large phallus. As they reached Fluttershy's room, their noses were struck by the sweet scent of Fluttershy's arousal; the sweet, nectar-like aroma of Fluttershy's desire for cock only made the Siri lose their composure. Unable to hold out much longer, the two burst into the room.

"Eeep?!" Fluttershy squealed in surprise, but that wasn't enough to stop her. Not even a moment after Zakia left her, Fluttershy had been voraciously masturbating; shoving nearly her entire massive dildo into her needy cunt. "Zebras?! Did the Master send you?"

"Zakia is sorry he is not currently able to stay and satisfy you fully." One of the Siri stated, his eyes fixed on Fluttershy's massive tits. "So he has asked us to keep you company until you are satisfied."

"Then come here and fuck my dirty cum hole!" Fluttershy loudly begged, using her fingers to part her pussy lips. The first Siri wasted no time and leaped at Fluttershy, taking only a fraction of a second to shove his entire length into Fluttershy's wetness. Arching her head back in pure pleasure, Fluttershy squealed in a euphoric moan. "OH CELESTIA!! SO BIG!! FUCK ME!!"

The Siri took this as a sign to begin, pulling his cock almost completely out; only to shove it back in. Within seconds, the Siri had started humping into Fluttershy at a rhythmical pattern that had his thick cockhead, punching at the mare's cervix. Though not as perfect as Zakia, the Siri was still enough to make Fluttershy wrap her sweat drenched legs around his body and begin to grind against him. The other Siri was not as assertive as his companion and chose to wait and watch. Fluttershy was so happy that a big cock was inside her, she didn't care that the other was watching; if anything, the feeling of being watched only made her pussy wetter and tighter.

"How did the Master endure this one?" The Siri asked, trying to keep in pace with Fluttershy's grinding. "Her pussy is devouring my cock!"

"Then maybe she needs to be struck from both sides?" The other Siri commented, stroking his hardened cock. “Let’s see if she is worthy of our Master.”

Knowing what his companion was planning, the Siri fucking Fluttershy grabbed the mare's shoulders. In a sudden jerking motion, the Siri inside Fluttershy pulled her up lifting her on his cock. The sudden change in position only made Fluttershy grow wetter as she came over the Siri's cock, her pussy only swallowing more and more of the thick length as she began to straddle the long shaft. With Fluttershy's mouth now closer than it was before, the unattended to Siri moved closer to the sex crazed pony. Seeing another thick and lip smacking cock slowly bobbing in front of Fluttershy, made her mouth water and her lips tremble in pleasure.

"Give it to me..." Fluttershy begged, leaning forward to try and suckle at the zebra's cock; only to have him back away, teasing her with how close, yet how far away it was. Fluttershy quivered in excitement, she wanted to have it, to taste the tasty zebra meat in front of her. "Please...let me have it...I want it...I want it!"

The Siri smirked as he brought the cock closer, only to pull it away again. Leaning further and further towards the tantalizing shaft, Fluttershy's massive chest pressed forward, pushing against the first Siri's face. Knowing this was all part of their silent plan, the bottom Siri reached out and wrapped his strong arms around Fluttershy's waist, crossing behind her sweat covered back. Within the same breath and motion, the bottom Siri thrusted himself upwards, driving his cock past the cervix wall and pressing his thick cockhead against Fluttershy's ovaries. Fluttershy opened her mouth in a squealing yelp as she felt her inner walls give way. But the top Siri gave Fluttershy almost no time to gasp as he grabbed the back of her head, tightly gripping her mane and shoving his cock to the hilt down Fluttershy's throat.

Fluttershy's eyes rolled back as she let her mouth cunt get fucked by this masculine Zebra. Her pussy only tightened as she felt her mouth being ravaged and her tongue acting as a lube to allow the cock in and out of her mouth with ease. The two Siri nodded their heads as they began to pick up the pace, the bottom opening his mouth to bite hard at Fluttershy's large and tender areola, as if he were trying to drink down milk and pleasure. Fluttershy's orgasm driven moans only served to reverberate in her throat, massaging the cock in her mouth. Fluttershy stopped caring about her own ability to breath, holding her breath and sucking on the cock in her throat, still putting effort into pressing her large hips against the cock inside her. Her body was beyond sensitive from the constant orgasms; she had long lost count or even cared to count.

"Ready for a good filling?" The Siri asked his companion, moving his fist down to bump fists. “This one deserves a good stuffing.”

"Oh yeah." The other Siri responded, bumping fists back. “Master is so generous to share such a tight whore!”

Fluttershy could feel the two cocks swelling inside her. They were ready to cum, she wanted them to cum. She wanted to drink and guzzle thick and musky loads in both her mouth and cunt. At once, both Siri pressed their sexual assault, shoving themselves so deep Fluttershy could almost feel the two cockheads touching inside her. Their initial load was heavy and thick, near burning hot as it poured in Fluttershy's twitching cunt and pulsating mouth. Lifting her arms up, Fluttershy grabbed at the back of the mouth Siri's thighs, pulling him closer as she drank at his cock to milk him like a suckling foal. The Siri below her had expanded his cock enough to nearly cork up Fluttershy's pussy entrance, denying his cum the ability to leave; letting only a little trickle out from the sides. Fluttershy felt her entire body scream in orgasm, not as loudly as Zakia made her feel, but it felt so close.

"She’s a strong one." The Zebra at the mouth commented, feeling Fluttershy still drink at his cock. "Maybe we need to really break her in?"

"You think the Master will be mad at us for breaking his toy?" The other Siri asked, gently pushing Fluttershy off as he rolled off the bed. Walking back to his discarded clothes, the Siri grabbed a small vial of light purplish-pink liquid. "We have a dozen of these." Taking another vial, he tossed it to his companion. "I think they can last several large spurts."

Knocking back the vials, both Siri felt the sudden surge of stamina and arousal. Their Siri training had allowed them to control their sexual urges, but their now revitalized cocks twitched at Fluttershy, who was now laying on her back, euphoric in the feeling of being full. Both zebras smirked as they felt the carnal desire to fuck Fluttershy into oblivion, she was slightly plumper from being so full of cum, even more so since Zakia's cum was still in her body as well. Fluttershy, seeing how hard the two Siri were again, cooed as she adjusted herself, turning to remain on her back but with her head hanging over the edge of the bed.

"Please, both of you!" Fluttershy moaned, cum still gurgling in her throat as she opened her mouth with both her hands, pulling her cheeks and her tongue dangling on the sides of her mouth. "Shove more cocks in my mouth, I want more warm, yummy cum!" Both Siri only responded with a nod and a pair of smirks.

For the next few hours, the Siri repeatedly fucked Fluttershy's body. Her mouth, pussy, and asshole were almost constantly filled with cock and cum. Eventually, the two lost track of how much they were cumming; turning to drink another vial to keep their stamina going. Fluttershy kept pace with the two, almost going the extra mile; making sure to always swallow and let their cum cover her. It wasn't long before the mare was nearly white from all the cum that coated her body. Her pink mane was the only part of her that still held color, but all the cum that was burst on and in her cuticles had left it a sticky mess. Despite this, Fluttershy continued to fuck and drink down like a heat driven glutton. But eventually, her euphoric, orgasm induced bliss came to a near crashing end.

"I...can't believe it..." One of the Siri commented, his sweaty and panting body leaned against the wall, emptied vials at his sides as they let small drips here and there on the rug. "She fucks like some demon."

"Worse than a demon." The other said, grabbing the sides of his head as Fluttershy sucked his cock clean of his remaining cum. "It's like she's sucking the very soul out of me!"

"Please fuck me more..." Fluttershy moaned, starting to stroke off the Siri's cock. "There's still more yummy cum in here right?" Fluttershy's soft hands only gently played with the zebra's sack, as if to try and stir the cum that lay inside. Both Siri looked at each other and nodded. In a sudden and drastic motion, both Siri leapt to their feet and ran out the room in a panic.

"We can't do this!" One shouted as he struggled to keep up with the other. "Her thirst is unquenchable!"

"Hurry before she wants more!" The other responded, keeping pace to stay with his companion. “Master can have her, I don’t want my soul sucked out of my balls!”

"Aww, no more?" Fluttershy asked shyly, rolling over to fantasize about Zakia and how he will fuck her again. "I guess I have to go to Master for more cock."
