Feral Conservation

Hopping into the school bus, nearly toppling over due to his heavy backpack as he swayed around from excitement, Zack scanned the rows of cubs already sitting down, trying to find a familiar face in the crowd while his tail whacked the seats next to him. The 8 year old boy finally spotted the one other grey wolf, his legs stirred into motion once more with a little help and a prod from another kid waiting to get seated behind him, his floppy ears swinging from side to side as he sprinted to the back of the bus, shouting out towards 12 year old girl, 
"Rachel, hey!" 
Rachel looked up with a smile, grabbing her bag from the seat next to hers and moving it between her feet, letting the boy sit down, 
"Hey, I saved you a spot."
Though the two siblings went to the same school, the few years of age difference still made it slightly exciting whenever the pair could hang out together at the school outside of yard time, school trips being one of the few such occasions that let the two pups stick together. The duo were obviously siblings based on just a quick glance, both having inherited their mother's eyes and snout, both of their furs a delicate mixture of darker and lighter shades of grey. Zack was a head shorter than Rachel, their size difference only accentuated by the fact that his ears hadn't quite yet begun to stand upright, flopping around every time he cocked his head to think intensely, never failing to amuse the teenage girl. Zack fell down onto his seat with a slight huff, having sprinted to the buses just to make sure he could get on the same one as his big sis, his tail still wagging in excitement as he scooped it onto his lap and out of the way as everyone who had been waiting behind him walked past,
"Do you know where we're going yet?" 
"Nope. I tried asking Robinson, but he didn't budge."
"D'ya think we're gonna go see a rocket being launched to space or something?!" 
Rachel giggled, 
"Probably not, I'm pretty sure there isn't a launch site anywhere within a day's drive of our school."
The boy looked disappointed for a moment, his mind soon distracted again as he began dreaming of the other possibilities for their mystery school trip just as the bus rolled forward, pulling out from the parking lot while Rachel peeked out the window, 
"Guess we'll find out the answer soon enough."

With nearly the entire bus holding their breath, the heads of dozens of cubs craned left to right and back again as everyone tried to figure out their destination, quickly reading any signs that whizzed past as the line of buses headed out from the centre of the city and towards the outskirts. One by one, light bulbs began flickering on in the cubs' heads as a few realised the direction they were driving, a low murmur falling on the bus, slowly getting louder and louder as they neared the end of the road, cheerful laughs and excited squeals filling the air as the last few people left out of the loop tried to figure out the answer. Standing up on his seat to see past his sister better, Zack finally joined in on the hollering as he spotted a giraffe painted on a sign in the distance, the head of the large creature poking above the trees, 
"We're going to the zoo!" 
With her tail likewise starting to twitch in anticipation, Rachel giggled at her little brother's excitement, gently nudging him to sit back down before he fell or was spotted by one of the teachers sitting up front. With every cub buzzing with excitement, the buses lined up at the parking lot and all of the kids were partnered up to make sure no one would end up missing, with the teachers each then grabbing a group of the students with them to go tour the place. The zoo had set up several different stations for the students all over the grounds, with each having a worker from the zoo to explain and lead some light exercises. The wolf siblings were captivated, learning about the animals living in Antarctica while watching penguins diving in their enclosure, feeding parrots as the worker told them how many species of bird migrated depending on the season, and laughing at monkeys performing acrobatics while doing a worksheet on ecosystems. Their tour eventually led them to a building tucked oddly away from the rest of the zoo, an odd scent immediately catching the pair's attention as soon as they stepped in. Both wolves sniffed around, getting a few odd looks from the other cubs as Rachel noticed that only the one other canine in their group seemed to be picking up the scent in addition to her and Zack, quickly dismissing the oddity as nothing but canine nostrils being delicate enough to pick up some weird smell. 

Walking into the building, the place seemed fairly different from the rest of the zoo, with electronic locks on all of the doors and a much more sterile appearance giving the siblings the impression that the space was some sort of an employees only area, not meant for the everyday guest to be poking around in. They also didn't see any animals around, though Zack made sure to peer through the windows of all the doors they passed as they were led through a maze of hallways lit by humming lamps rather than natural light. From the peeking, the boy could make out a lot of complicated machinery and chemicals, most of the building seemingly taken up by laboratories. The group was led down an elevator underground, with the weird scent only getting stronger as the students went down, getting potent enough for the three canine cubs to gently scrunch their noses as soon as the elevator doors rolled open. The smell wasn't necessarily unpleasant, in fact neither wolf could quite say whether they liked or hated it, but the sudden assault on their nostrils still elicited a reaction from the trio, while none of the other species seemed to even smell it still. The group headed down a final winding hallway before coming to a ledge overlooking a small enclosure, windows separating the cubs from a pack of feral wolves. They all pressed against the glass in awe, mesmerised as the large canines stalked around the enclosure, appearing to be riled up by something, though none of the beasts even glanced towards the direction of the kids. Rachel and Zack both watched the largest of the pack trotting right behind a slightly smaller one with autumn brown fur, the siblings both turning red as the large wolf suddenly mounted the other, panting as he gave a few thrusts, his member glancing off of the female's lips and slipping below her belly, letting the whole class see his red rocket dangling in the air before he readjusted and finally found his mark. Grunting and growling, the two wolves mated with little regard to the audience of half-horrified and half-intrigued cubs, stifled giggles echoing around as the teacher cleared his throat awkwardly.  

Unable to peel her eyes off of the horny feral couple, Rachel felt slightly warm below her collar as well as she watched the leader of the pack making the female wolf his bitch, the glass between them and her not quite enough to entirely dampen the needy soft whimpers or the wet slap of his shaft gliding into the dripping spade. Just as the large male finished up and tied the brown wolf with a snort, a few of the other wolves beginning to circle the pair, a door opened behind the students with a swan stepping out. She was dressed in a lab coat sporting the zoo's logo, a pen in one hand and a clipboard in the other as she smiled brightly, welcoming the group, 
"Hey everyone, and welcome to my little corner of the zoo! My name is Christina, and I'm in charge of a team that deals with a very important aspect of feral life, especially in captivity. Does anyone here know what 'estrus' means?" 
The cubs gave each other quick glances, seemingly at least not sure enough of the correct answer to risk blurting out what they had in mind, the bird's eyes scanning the group for a moment before she continued,
"I'll give a hint: it's not something that just ferals deal with, but with us we usually call it going into heat rather than estrus."
The crowd still stayed quiet, though the expressions on many of the kids' faces revealed that they knew the direction the conversation was heading into. Rachel finally lifted her hand up since the awkward silence lingered, broken only by the panting of the ferals as round two seemed to have broken out in the enclosure, a nod from the swan letting her answer, 
"It's like… when a woman gets all… you know. It's when a woman can have a baby the easiest."
"Correct, well done. Whether we use estrus, heat, rut, or some other name, these all describe a state when a female is at her most fertile. My team's job is to both ease the unrest caused to a feral when going into estrus, as well as to make sure that the population of all the species in our care keeps stable. So basically, we help the animals here make cute little babies!"
Christina stepped over to the glass, peeking down at the wolves still getting busy with one another, 
"As you can see, currently we have a pack of Canis Lupus, or wolves, here at our station. We usually sequester any animals in estrus here, as the pheromones they emit can cause restlessness in some of the other ferals, they can actually even affect some anthros!" 
Finishing her sentence, the avian's eyes lingered at the pair of wolf siblings before she quickly continued, making no big deal of the outright feral orgy happening right behind her back, 
"Now, I've got you all a fun little worksheet here, this word hunt is all ab…" 
The woman's words droned on in Zack's ears, but his gaze was focused on the ferals, a strange sensation clouding his brain as he stared at a female wolf getting stuffed from behind, his throat going dry as her mate pulled out, giving him a flash of her overflowing spade before another male quickly stepped up for sloppy seconds. 

With the crowd of students spreading out into a few groups to work on the given assignment, Zack was finally stirred from his daze, stuffing his face down into his worksheet to hide his blush as both wolves headed off into the corner, unusually silent with both getting flustered after the lewd show they'd been given. Christina toured the room, making sure everyone was getting the hang of the assignment, but kept constantly glancing in the direction of the two canine siblings in the corner, hiding a slight grin. She eventually made her way to the two, her hands behind her back as she leaned down, almost whispering as she spoke, 
"So, how's the work going?" 
Both wolves nodded and muttered something, unable to make eye contact with the woman, the wild scent of the ferals burrowing deeper into their heads with every breath they took, leading to some rather awkward effects on their bodies. Recognising the duo's uncomfortableness, Christina glanced over her shoulder, making sure the teacher was preoccupied with the other students before turning back, 
"Remember what I said about those pheromones? I guess you're getting to experience that first hand, sorry about that, I must've missed that we'd be having canines as visitors today. If you want, you could finish up the worksheets at our break room. It's a bit away from the enclosure and has pretty good air conditioning, might ease the situation a little."
Rachel and her little brother looked at each other, quickly nodding as the swan stood up tall, trying to disguise her smug smirk as a friendly smile as she motioned towards the door, 
"You can go just down the hall there, I'll be behind you in a second."
Christina walked up to the teacher right after the cubs had left the observation room, telling him that the siblings were feeling ill and going to lay down for a while in the first aid station, following after the two after making up the excuse. She led the kids into the staff break room, pouring the pair a glass of juice each, slipping a pill into each before handing them to the thirsty wolves as they sat down to work. Rachel thought she was starting to feel better, the fog in her brain resending slightly as soon as she stepped away from the pack of ferals, but only minutes later she was starting to feel even worse, barely able to hold up her head. Just before she passed out, she watched Zack topple over onto the table, her chair falling down as she tried to reach out towards the grinning bird, only a weak groan coming from her as she tried to yell, the world slowly turning dark. 

Moaning quietly, Rachel rubbed her head, her vision still blurry as she lied on the floor, rolling onto her back. The girl didn't know exactly how long she had been out, but it didn't feel any longer than an hour, squinting as the bright lights above her made the teen's eyes ache. With her vision slowly coming back, she looked around, confused as to how the break room seemed to have gotten a whole lot bigger, and much cooler, a slight chill making her shiver. As if all of the sleepiness had been slapped from her, Rachel sat up with a squeak as something wet and cold suddenly pressed against her nethers, her heart nearly stopping as she found herself face to face with a feral member of her species, the beast's nose pressed against her crotch. She looked down to see that she was fully nude, quickly covering up both her pussy and her breasts as she scrambled to back away from the wolf, squirming away until she bumped into something soft and furry, peeking over her shoulder to see yet another feral staring her down with a curious look. The wolves circled her, sniffing and giving little licks all over her body as she trembled and tried to stay as still as she could, hoping that the licks weren't to see just how tasty she'd be as their next morsel, struck by just how ginormous a feral wolf truly was not that she could see one up close and personal. The girl noticed that she was in the enclosure she'd been peeking into only minutes before passing out, immediately looking up at the spectator's perch in horror, fearing that she'd see all of her classmates laughing at her. Instead, the cub only saw Christina, clipboard still in hand as she scribbled something down, grinning at the teen while shouting through the glass,
"Good, you're awake. The boys usually like their partners to be a bit more active, the dead-fish routine is a big hindrance to their virility I've found out~" 

Holding her breath as the largest of the pack, the very same male she'd watched ploughing a female, sniffed at her belly, Rachel looked around in a panic, searching for her little brother, holding back moans as the feral's nose tickled her. She quickly saw him lying only a few steps away from her, his eyes closed but his chest still rising peacefully. Zack was going through a similar inspection as she was, though he'd mostly grabbed the interest of the female members of the pack, several wolves pacing around him, licking their lips and prodding at his erection with their noses. Rachel was momentarily stunned by her sibling's cock, surprised at just how big he actually was, his red rocket more resembling the adult's she liked to watch on the Internet rather than an 8 year old boy, though she quickly shook off the intrusive thoughts and tried to focus on his well being, her brain completely clouded by the heavy musk of a dozen wolves in heat. Christina noticed the girl staring at Zack, chuckling quietly, 
"Don't worry about your brother. The drugs I gave both of you are wearing off a little slower on him since he's a fair bit smaller than you, but he'll be up and about in no time~" 
Finally gathering up her nerves enough to open her mouth, still trying to crawl away from the incessant sniffing with her arms covering up any of her naughty bits, Rachel yelled up at the swan in confusion, 
"Wh…what happened, why are we in here?!" 
"Very good question. To ensure that our animals have healthy and genetically diverse populations, we occasionally have to get a little… outside help from some of our guests. Thankfully, your school sent out a list of everyone who was coming to visit, it wasn't difficult to figure out each of your species after that. I wish you could've seen my face when I saw that I'd have not one but two wolves dropped on my lap at just the perfect time, you are going to do some wonders for this pack!"
Realising what the woman was saying, Rachel's worried look only grew more dire, her eyes wandering down between the back legs of the two wolves who had taken an interest with her, spotting their heavy ballsacks and sheaths swinging around as they huffed in her scent, her cheeks painted red as she felt her own loins burning. 

Too anxious to move her hands, Rachel could only watch as the two males got more and more curious with her, quickly catching on that she could be a good relief for their constant lust, the situation devolving into the pair growling, shoving, and snapping at one another as they competed to see which one could get her her first. The leader of the pack emerged victorious to no big surprise, the other male, adorned with a scar on the side of his snout, sulking off a few steps away to wait his turn, sitting down and keeping his eyes on the prize. The alpha's snout came only an inch away from Rachel's face, his nostrils flaring as his hot breath tickled her neck, making her shiver as a tiny moan accidentally slipped from her maw. Though still on the edge, the teen couldn't help but to move her arm away from her chest, very carefully stroking the beast's side as he leaned down. His fur was much more coarse than hers, but still felt wonderful as she ran her fingers through it, a wild yet pleasant musk rubbing off onto her arm as she pet the animal. The wolf's muzzle hovered in front of her breasts for a moment before he gave the puppy's tits a lick, dragging his tongue over one of the soft mounds, drawing a pleasured hiss from Rachel as his hot tongue teased her nipple. With her breath quivering, the canine gently moved towards the beast, pressing her upper body against him as he continued lavishing her chest and belly with his strong tongue, her eyes closing as she whimpered softly. The hand between her legs had previously been there just to hide away her slit, but her fingers were soon moving and massaging her tender lips, wetting the tips of her digits as she moved her other hand further down the male feral's side. The swan watching her, the unconscious brother lying and being licked next to her, the entire zoo around her, it all disappeared from her mind as soon as her fingers felt a warm and wet member underneath the wolf's belly, the stiff tip pressing against the palm of her hand as he huffed. Biting her lip, Rachel wrapped her fingers around the cock, letting the alpha gently hump her hand as more of the girth emerged from his sheath, easily filling up her grip as his muzzle wandered further down her body, her thighs getting wet with a combination of her honey and his slobber. 

Unable to resist the temptation, Rachel got down on her hands and knees, pushing her head underneath the alpha as he eagerly lifted up one of his front paws onto her back, her eyes filling with a primal desire as soon as she came face to face with the feral's red rocket. Just like the male himself, the girth was much bigger up close than it had seemed from the observation perch while it was slamming in and out of one of the females. The heavy shaft dangled in the air, pulled downward by the heft of the half-inflated knot, a near-constant drip of watery and thin precum drooling from the tip as the wolf's tail wagged in excitement, his back paws marching in place as he waited impatiently, seemingly not entirely unfamiliar with this sort of contact with people. The heady musk that had gotten the young teen drunk from lust was at its absolute strongest as she inched her muzzle closer to the cock, grabbing the knot in the palm of her hand as she panted just as hard as the alpha, feeling the rock hard girth throbbing in her hand, the entire length still painted with cum and juices from the female members of the pack. Rachel hadn't ever even gone beyond first base with a boy, and she certainly hadn't thought about getting naughty with ferals before, but she followed her instincts and a few tricks she'd seen online as she brought the tip of the wolf's cock to her lips, opening wide and taking it in. The cub lapped her tongue over the beast's tip, taking in his texture and the taste as she moaned against the dripping member, her eyes rolling back in wonder as she reached her free hand beneath her belly, shoving a finger into her needy mound while she swallowed down a few more inches of the male's cock. With her estrus-addled mind focused entirely on the alpha in her mouth, Rachel had almost forgotten about the other male waiting for his turn right behind her back, the scarred wolf taking her bent-over pose and spread-open slit as an invitation. Shoving more canine dick down her throat, the girl was startled to suddenly feel a pair of paws thrown onto her back, pulling off the alpha to see the other male lining up with her cunt. Even in the horny stupor that she was, spit and pre running down her chin, Rachel was still rather apprehensive about letting a feral wolf mount her with very little foreplay, trying to wriggle out from underneath the two males as the scarred one thrust against her ass cheeks, his length searching for a warm hole to plug up. Noticing that she was very much pinned in place, the teen finally resorted to yelling out, groaning as she tried to push off the lusty pair, 
"H… hey! Bad boy! Leave it, please?!" 

Stirred awake by his big sister's shouting, Zack's eyes finally opened by a sliver, his head shifting in confusion as he tried to squint at the quickly darkening sky above him, his lungs filled with a potent scent that made his entire body tingle from his ears to his toes, especially his sensitive member. A second later, the boy discovered that the dimming light wasn't the sun setting, but an approaching feral flank instead as a lithe wolf sat down right on his face, her sopping wet spade pressing on his forehead and giving him a sloppy kiss as he jolted, his hands groping at her ass in panic, his confused yells buried underneath her tail. The beast tried to grind her backside against the cub for a moment before noticing that her aim hadn't quite been right and standing back up, leaving the shocked pup gasping as he stared up into the feral's striking blue eyes, a wet spot left on his forehead, her glistening spade hovering right over him. He looked down to see himself fully erect, another female cloaked in light brown fur nuzzling his shaft as he whimpered inadvertently, still feeling dizzy as he tried to take in his surroundings. Zack was just barely able to see his big sister trying to struggle free when the small wolf squatting above him decided to sit down for another try, this time planting herself just right. Her cookie squished against his lips, her tailhole rubbing on his nose as she began grinding and humping his muzzle, her tongue lolling down her chin while her tail waved high in the air. Though he was utterly confused, and half certain that it was all just one of those weird dreams that left his boxers all sticky in the morning, Zack was sufficiently tipsy from the two ladies' scent that he went along without any questions, wrapping his arms around the blue-eyed beast's flank and opening his maw wide, lapping at her pillowy soft lips for a few licks before pushing his tongue all the way inside, drawn in by the incredible taste and smell. The brown-furred wolf laying next to the boy put her maw to good work as well, slurping at his knot and licking up all of the delicious precum that poured from his tip like a fountain, paying no attention as the kid's legs squirmed and flinched with every touch of her wide tongue. 

From the corner of her vision, Rachel could see her little brother getting into the feral lifestyle, muzzle deep in one female while another suckled on his cock. She didn't have too much time to admire her sibling's oral skills however, as she was dealing with her own set of horny beasts, straining as she tried to pull out from under the males while they drooled over her, licking at her neck and giving her gentle love nibbles. Stuck in place, she wasn't quite able to get herself free before the scar adorned wolf behind her shuffled into a better position, his front paws kneading her back as his tip poked between her thighs, finding her wet opening. Realising that she wasn't about to get out of the predicament, Rachel decided that she might as well just go with it, the idea of a hard feral bone buried balls deep in her cunt sounding better by the second as the alpha's girth dangled in front of her nose. Pulling the larger wolf's cock back into her maw while bending over and sticking her flank against the other's crotch at the same time, the girl tried to prepare herself for what was to come, bracing herself as the male on her back lined himself up. With a swift thrust, the beast was inside of Rachel, her blissful moan echoing out across the enclosure for just a moment before being cut short, his buck shoving her face deeper against the alpha's dick. Stuck in a spitroast between two ferals nearly twice her size, the young teen could do nothing except enjoy the ride as she was taken from both sides, and that was exactly what she had in mind, her entire body quivering as the rapid fire pounding against her pussy rammed the other wolf's cock deep into her throat, the scarred feral's frantic panting into her ears drowning out all other sound as she grunted, needy for more. She stretched her maw open as wide as she could, trying to take in every inch of the pack leader's girth while her slit was stretched open, just barely stopped by his knot as he humped her face, his hefty sack flopping against her chin as he let out a small howl. With a small choke, Rachel was filled up from both sides, a knot sliding into her pussy and tying her just as the alpha creamed her throat, both of her holes overflowing with feral seed as she struggled to keep up on all fours, spasming as she came against the throbbing knot sealing her mound.

With his hands full of wonderfully soft feral ass, Zack shoved his muzzle deeper into the female's fortune cookie, eating her out with with bestial gusto as her juices trickled down his throat, quenching the thirst that the wolves' scent had awakened in him. With his face buried beneath a mound of soft fluff and quivering flank, the boy couldn't see anything that the other feral lady was up to between his legs, the brown-furred wolf feeling the itch underneath her tail getting more and more irresistible as she licked his dick. Her carefully tuned nose could smell that he hadn't yet bred a female, his strange yet familiar enough scent driving her wild as she whined and pawed at his thighs, a thin strand of sap leaking between her back legs and smearing across her ass. The female was generally used to being the passive half when being rutted, but since this male didn't seem to want to get up and mount her no matter how clear she made her signals, the wolf lady was forced to take the situation into her own paws. Mimicking the blue-eyed member of her pack that was currently sitting on Zack's face, the autumnal beast squatted on top of the cub's crotch, awkwardly shuffling around and swaying her backside until she felt his spit-coated tip poking underneath her tail, adjusting her pose and bringing the virginal girth to her waiting spade. Sitting down, she buried the bone nearly up to the knot as she yipped sharply, her tail sweeping the kid's belly fur as she began riding him. Surprised by the eager tongue on his dick suddenly being replaced by the sweltering heat and vise-like grip of a feral cookie, Zack moaned hard into the other wolf's mound, just barely able to get a glimpse at his shaft pistoning in and out of the snug cunt whenever the female on top of him allowed him to take a gasp of air. With the storm of smells, sensations, and tastes assaulting him from all sides, Zack was already hanging by a thread, the brown-furred wolf's pussy swallowing up his knot being the last straw as he began shuddering underneath the insatiable pair, his arms and legs trying to wrap around anything he could get hold of as he fired off a huge load deep into the feral's waiting womb, his frantic licking and suckling pushing the small canine sitting on his face over the ledge along with him as well. With the two bestial ladies squirting on his head and crotch, Zack opened his maw wide and enjoyed the lewd shower. 

Struggling to swallow down the volume of cum being pumped down her throat, Rachel nursed on the alpha like a baby suckling from a bottle, her face going bright red as she took it all down in one breath, the wolf finally pulling his shaft out from her muzzle and stepping away as she collapsed onto the floor, coughing and sputtering with half of her face drenched in feral seed, a blissful smile still on her lips. Though entirely limp, the teen's backside was still sticking up towards the ceiling, her pussy lips holding tight to the throbbing knot in her as shot after shot gushed through her cervical opening, giving her a taste of what it might feel like to be knocked up as she groaned softly and put a hand against her puffed up belly. The scarred canine tied to Rachel gave a satisfied growl before turning around, tossing one of his back legs over the cub as he shifted to be ass to ass with her, a slight hint of his red cock still peeking out from under her tail as he stood around, enjoying her subtle clenching while he emptied the rest of his load. Right next to the girl and her two suitors, Zack was finishing up with his ladies as well, nearly running out of air before the little wolf eventually lifted up her backside from his muzzle, leaving him panting and licking his lips, his entire face painted with her sensual fragrance. The boy looked down to see the other beast standing up likewise, his butt pulled off the floor for a moment as her spade debated letting go of his knot, his mouth twisting into an ecstatic grimace as her walls twitched around his sensitive shaft, finally letting him go with a lewd pop as his cum cascaded from her depths. The wolf lady peeked over her shoulder and gave the little boy a stern look, no mutual language necessary for him to understand exactly what she was after as he flopped to his belly and crawled behind her, nuzzling his mouth under her tail and cleaning up the mess he had just made. Since the brown-furred beast had already had to wear the pants in their short relationship, she decided to adopt another custom from the males of her pack, wanting to mark the cub as her mate, her tail suddenly turning up as a warm stream splashed his face. Zack was initially about to pull his snout back from the musky spate, but quickly decided to let the urine wash over his chest and face as he focused on devouring the thick cream flowing from her spade, her heated panting bringing a blush to his face as she backed up and rubbed her nethers on his nose. 

Watching from her advantage point with a spark in her eyes, Christina scribbled down note after note as she studied the siblings and the pack, her scientific calm occasionally broken by a flushed look or a soft giggle as she tried to focus as best as she could. The kids both pulled free from their feral partners, with Zack crawling out from underneath the lady wolf once the spade he'd filled up was polished to a shine, and Rachel whimpered in lust as the knot was yanked from her delicate lips, leaving her creamy filling to gush out and coat the back of her legs as she gathered her strength. That didn't mean that either guest was left alone by their grateful hosts however, with the four wolves quickly surrounding the pair, licking and nosing them, gently nudging them around until the siblings were face to face and on all fours, their whiskers nearly touching. Rachel wasn't sure whether the pack had herded her and her brother into the position, or whether it was just pure coincidence, but the pups didn't have long to stare at one another in an awkward silence before they were both mounted by the ferals, with the alpha taking the teen's tailhole and the smaller male taking the boy. Both siblings hissed gently as the wolves snatched their anal virginities with the feral passion and strength they'd come to expect, the two breaking out into animalistic howls and grunts as they were pounded, their holes gripping against rock hard shafts. With lust quickly overtaking sanity, Rachel reached her maw towards the first thing that could occupy it, which just so happened to be her little brother's lips, their tongues wrapping together as they exchanged feral tastes, with the girl getting a sample of sweet honey from a spade while Zack got to see what the girth in his tailhole might've tasted like. With her facade breaking down as she stared at the wolves humping away at the kids, Christina finally allowed herself a break, holding her breath as she opened her lab coat and dipped a hand into her pants, giving a deep moan as she rubbed her panties. She might've started the program with only the animals' wellbeing in mind, but she couldn't deny that a sliver of the feral lust had definitely rubbed off on her with every session she'd supervised. 

The unrelenting and breakneck pounding continuing until both males shot their load, the smaller wolf managing to tie Zack while Rachel's hole was just a tad too tight to fit in the entire bulb before blastoff, the siblings broke off their kiss as cum trickled from their tailholes, their eyes filled with crazed lust. Rachel pulled herself off from the alpha and pushed herself underneath her younger brother, grabbing his cock and ramming it between her legs as he whined and grabbed a mouthful of her hair, a knot still throbbing in his ass. The other ferals crowded around the siblings, licking and humping wherever they fit as the entire pack descended into a single orgy pile, grinding and thrusting on any hole that they could find. The swan nearly lost footing as she whimpered, leaning on the glass as her juices ran down her legs, her pen almost breaking in two as she shoved it into her beak to stifle her cries. Still riding out her orgasm, Christina glanced down at the mess of wolves writhing around in the enclosure, debating whether to go in and fetch the siblings to get them cleaned up, or whether to let them stay for an additional hour or two, her mind already working on a good excuse to give to the school.
