Two Wild Beasts

Gwen laid sprawled out on the couch, the 16 year old giraffe's head slumped on a pile of pillows as she reached for a drink, using her long and agile tongue to wrap around the straw and bring it over to her lips as she sipped the ice cold soda with a sigh, brushing her long white hair out of her eyes. Laying at the teen's feet on the other end of the sofa was the family dog, the feral great dane lifting up her head as she spotted Gwen's 12 year old brother scurrying up the stairs from the kitchen, smirking slightly as she turned to the older giraffe, her tail thwacking against the back of the sofa. Though feral, the dog was fully sentient and still able to talk just the same as any anthro, the two females sharing a particular passion for gossiping about the lone male of the household, 
"I think Gearth might be trying to hide from us again~" 
Gwen giggled and peeked over the sofa, whispering back to her loyal canine companion as she just barely caught her sibling's tail disappearing up the stairs, giving Ivy a wink, 
"Looks like it. Maybe you ought to go take a look at what's going on in his room again~" 
Just as the two ladies were snickering amongst one another, Gwen's mom appeared from the bathroom, her purse tucked at her side as she glanced at her makeup in the mirror, pacing around in a slight hurry as she made sure the bags stacked up near the front door had everything loaded. After going through her luggage one last time, she poked her head into the living room, 
"Alright, I'm gonna take off now, you're sure you three are going to be alright for the weekend?" 
"Yes mom, I think I can probably stay alive for a few days."
"Not just you, you're gonna need to look after your brother and Ivy as well."
Gwen sat up and wrapped an arm around the great dane, pulling Ivy to her side and nuzzling the canine as she received a playful lick on her chin, 
"We'll all be fine, don't worry."
"Alright, I'll remember that promise. Call me if you need anything, love you all!" 
The girl and Ivy both shouted out a goodbye to the mother as she grabbed her bags and walked out, the pair watching intently from the sofa, tracking her through the window as she got into her car and took off. As soon as the adult had left the driveway, Gwen and her dog's smiles took on a much more naughty tone, their eyes switching from the kitchen window to one another. 

The two girls laid back down on the sofa, with the giraffe spreading her legs to let her best friend sprawl out on top of her, the dog nuzzling her chest as she moaned softly, petting and scratching the great dane as the pair relaxed. They had both just started their heats that morning, just starting to experience the first symptoms of the bothersome affair, the duo feeling more on the edge by the hour as their estrus crept up on them. The heat hadn't quite progressed far enough for the mom to have noticed anything out of the ordinary, but a male's nose was far more sensitive to the scents of a woman in heat, even if said woman happened to be his older sister or a feral dog. The approaching rut was the main reason for Gearth acting much more awkwardly than usual, having picked up the tantalising fragrance the first thing that morning, his blanket almost falling off of him due to the even worse morning wood than what he was used to. The cub had tried to stay out of the way of his family as best as he could, not wanting to make it obvious that he was having a very hard time controlling himself around the two ladies in heat, only slipping out of his room for the occasional drink or snack. The boy however didn't question at all why the two females were in heat at the same time, a very odd coincidence for any pair unless they were hooking up, a connection that Gearth hadn't seen in his panic to keep his accidental erections under control. Unbeknownst to the rest of the family, Gwen and her pooch were indeed getting very intimate nearly on a daily basis, sneaking in the occasional licks and fondles when all alone, making sure that neither needed to worry about being pent up. Their close friendship started at the giraffe's very first heat at the age of 12, the canine's precise nose having picked up the little girl's problem before she even knew what was going on with herself, an evening of quiet whispering and giggling quickly turning into the great dane providing some hands-on relief to her. From that point onwards, Ivy spent most of her nights sleeping right alongside the big sister, getting up to all sorts of trouble with each other whether in estrus or not. Their heats synced up after just a few cycles because of their constant playing around, a change that neither party objected much to, the few days of rut often ending up being some of the most fun and pleasurable times of both of their lives. 

Stuck in his room, Gearth groaned while squirming in his bed as the delectable scent of his big sister and the feral lingered in his nose, only growing stronger even with his window open and fresh air pouring in. The boy could barely focus on anything, his pants tenting up as his half-flared shaft pushed further out of his sheath, the mottled girth straining uncomfortably against his shorts. Even after jacking off several times already, he couldn't find any hint of relief, knowing from experience that his situation would only grow worse as the two girls' heats progressed through the weekend. The young giraffe tossed and turned in his bed for some time before finally shaking his head in frustration, rising up to his feet and pacing around his bedroom, coming to the conclusion that he absolutely needed at least a tiny break from the torment to clear his head, not wanting to risk doing something dumb enough that might get him caught by his sibling. Gwen and the great dane were cuddled up to each other on the sofa, the giraffe's hand slowly sliding down towards the canine's spade as she massaged her hips up against the large hound, both panting passionately. Just moments before the scene would have blossomed into full on fornication, her little brother's door flung open and he hurried downstairs, trying to keep his head down while scampering towards the front door, 
"I'm… gonna go hang out with a couple friends!" 
Gwen peeked over the sofa, grinning as she saw the bothered boy pulling on his shoes and jacket, constantly keeping his back towards the two females to hide his hard on, 
"Alright, don't stay out too long~" 
Inhaling the even stronger musk of an excited pair of ladies while trying to hurry outside, Gearth just about sprinted out the door and didn't stop until he was on the other end of the street, gasping and sweating as he felt his equine cock throbbing against his shorts, pulling the band of the pants off of his crotch. Leaning against a tree, the blushing cub twisted his head from side to side, making sure that no one was seeing him in this state before trying to calm himself down, taking in the fresh air of the outdoors. Even without the stink of estrus making it impossible for him to think straight, he still found it very difficult to get his lower half to obey him, a big stain of precum soaking straight through his boxers and wetting the front of his pants as he sighed, sneaking off to find some private place around the neighbourhood, hoping that he could work off the tension now that he wasn't stuck sniffing the two ladies. 

As soon as the boy was out the door, Gwen sprung into action, reaching down to tug at her pants while her other hand felt up underneath the great dane's tail, the feral's weighty huffs warming up her cheeks as she dipped a finger into both of their cunts. She felt the dog's soft spade squeezing her digit as she clenched her thighs around her hand, digging into her own puffy slit while Ivy licked at her neck. The giraffe's equine pussy had already drenched her pale blue panties while the pair had been cuddling, but with her fingers in the mix the girl's honey gushed directly onto her pants and the sofa, marking the cushions with a horny aroma. Ivy whimpered against her owner's chest, riding the teen's fingers for some time before pulling herself off, wanting something more than a mouthful of chest fluff to fill her maw with. The thirsty dog went straight to the tap, hopping between the giraffe's legs and yanking the girl's pants off with her teeth, diving her muzzle into the sister's cunt. With her head hanging over the armrest and one leg thrown over the backrest, Gwen let out all of her lust in animalistic moans and howls, her fingers tangled up in her long white hair, her eyes closed as she drooled all over her shirt. She felt the dog's tongue slithering into her pussy, lapping at her walls as her lips winked over the great dane's muzzle, soaking the fur on the canine's face as she squealed in bliss, the usual pleasures of being eaten out only intensified tenfold by her incoming heat. Ivy's nose was overwhelmed by the scent of the girl as she lapped at the slit, her own spade winking similarly while her tail wagged furiously, her back legs already saturated with her own juices. Relishing the wonderful taste of her owner, the pooch let her eyes roll back as she lapped up the giraffe's sap, moaning into the tight and wet tunnel as she felt the familiar need growing between her legs. The pair held nothing back when it came to screaming and grunting in ecstasy, taking full advantage of having the house all to themselves for the time being, letting their lust vent out in every way imaginable. 

With her lips wet and her nose glistening with her owner's dew, Ivy pulled her snout out from the giraffe's cunt, licking the syrup from her lips as she stood up with a huff. She lined herself up on top of the girl before lifting up her tail and squatting down, pressing her swollen spade against the teen's pussy, the duo moaning in unison as she ground their mounds together, the two juicy peaches rubbing up as she humped the cub. The great dane grinned as she looked down at Gwen's red face, her tongue hanging out the side of her maw, 
"I think Gearth's had a pretty hard time dealing with the last few of our heats~" 
The giraffe giggled in between her panting, 
"I know, I think the poor boy is probably just as horny as you and me."
"He's also been trying to catch a peek under my tail a few times when he thought I wasn't looking. He isn't too good at hiding it though~" 
The canine laughed and thought back to the many times that she'd caught Gearth tending to his male needs as she continued massaging her cookie on the sister's slit. Though Ivy was able to talk, she was still treated just the same as any other feral, which meant that the boy didn't much mind even if she hung around his room while he was jerking off. She'd noticed an increasing interest from both siblings towards one another through the past few months, spotting the cub staring at his sister even when no one was dealing with rut and sensing an increase in curiosity from Gwen, the dog catching onto the fact that she might just be able to make some magic happen if she pulled the right strings. Ivy huddled down and squeezed her drooling cunt down onto the giraffe's winking pussy, thrusting against the girl like a male as she cooed into Gwen's ear, 
"You know, he's pretty big down there for his age. And he's got some pretty impressive loads, trust me~" 
Seeing the glint of interest growing in the teen's eyes, she continued, 
"I almost caught a rope on my face from the other side of the room while I was watching him jack off the last time around, the boy had to use a towel to clean up his mess. And his tongue~!" 
The dane punctuated her words with a heavy moan, 
"It's just as long as yours is! I've definitely caught myself thinking of just how good it'd feel in my spade a few times~" 
Caught up in the image of her little brother spraying a load all over her mound just as the dog's soft lips rolled over her clit, Gwen lost her cool and broke down in squeals as she came, spraying her juices on the great dane's crotch while spasming. Going completely still for a few moments, the giraffe finally lifted up her head, giving the feral a wink while letting her tongue dangle down, patting her chest as she glared at the glistening spade, sticky strands of both girls' juices connecting the pair as Ivy stood up, 
"Alright, c'mere, it's your turn to cum~!" 

After nearly an hour of licking, fingering, kissing, and scissoring, Gwen and her loyal companion were left drained and exhausted on the sofa, cuddled up to one another, gasping for air. The stark naked giraffe could just barely lift her head off her living and panting pillow, glancing at her phone to see that they had spent quite a good chunk of time on their hedonistic revelling, 
"I think it might be a good idea for me to get to the shower, before Gearth comes home and finds me stinking like I've spent a week living in a pound~" 
Giving the great dane one last kiss on the head and a scratch under the chin, Gwen stumbled off the sofa and shuffled towards the stairs like a zombie, picking up another piece of clothing that she had tossed off every few steps. She staggered to her bedroom, making a pitstop to toss her musky clothes into her laundry bin and to grab a towel before heading into the shower, sighing softly as she turned on the steaming hot water. Ivy likewise took the opportunity to clean herself up, though she preferred a good tongue bath to a shower, hopping to the floor and stretching on the soft carpet before curling up, lifting one back leg and sticking her muzzle under her tail, purring like a kitten as she lapped at her spade. A handful of minutes after the two ladies had parted ways, Gearth returned from his little expedition, praying that the clear air and exercise might've fortified his mind to stay focused at least until nightfall. Unfortunately for the boy, his hopes were immediately dashed the second he stepped foot inside of his home, the session of debauchery with all of the windows closed leaving the entire house stinking like a whorehouse, the scent causing his boner to return with a vengeance as soon as the heady scent hit his nostrils. Still lingering on the doorway, the tip of his erection almost poking out the top of his shorts as he shivered and whimpered, Gearth thought about stepping out again, hesitating until the canine called out towards the open door, 
"Gearth? Is that you?" 
With his return already discovered, the cub knew he couldn't just turn and run without raising some awkward questions, forcing him to step inside with a sigh, closing the door behind him as he snorted, every breath causing his head to fog and his balls to throb, 
"Y… yeah… I'm back…" 

Gearth waddled over to the living room, peeking from behind the corner and letting out a slight sigh of relief as he spotted no signs of his older sister, hearing the shower running upstairs. He didn't feel quite as anxious about letting the great dane see the lump in his pants, though he still felt very much on the edge, sighing loudly as he sat down on the sofa. Ivy had to hide her smirk as she pretended to focus on cleaning her paws, watching the boy accidentally lay his hand down right where both her and Gwen had been leaking all over, the dampness of the cushion getting him to quickly jump up to his feet. The cub inspected his wet fingers for a second before giving them a sniff, the incredible smell nearly knocking him out on the spot, the giraffe leaning over slightly as his cock jutted against his pants. Gearth wasn't entirely sure what had happened on the sofa, but he had to force himself not to jump down on his knees and jam his face against the soaked cushions, holding back a whimper as he stepped away and tried to tug at his shirt to conceal his bulge, gulping while turned away from the canine, 
"Did… did you… uhh…" 
The boy turned his head to see Ivy laying on her belly, her flank facing him and her tail curled off to the side, her tongue still lapping at her paws as she pretended to preen herself, stealthily keeping a close watch on his open mouth from the corner of her eye. Gearth had certainly been more than slightly interested in experimenting with the wild side of things, having snuck a few peeks at the great dane's undercarriage here and there, but he hadn't ever seen the dog's goods up close while she was in the midst of her heat, the jaw dropping sight leaving him breathless. He knew that he couldn't handle a single second longer without having something wrapped around his quivering equine girth, spinning on his heels and muttering out some incoherent excuse as he stormed up the stairs, hoping that her sister's shower break would give him a minute or two of risk-free privacy in his bedroom to relieve himself. 

The young giraffe hurried upstairs, grunting and huffing as every step made his stiff package grind against his shorts, just about to step into his bedroom when he noticed his sister's room's door just slightly ajar, a flurry of devious ideas pouring into his head as he stared, unable to think about the risks of his fantasies due to the cloud of lust fogging up his brain. He snuck up to the bathroom door, listening to Gwen humming inside as water rippled against the floor, the boy for once actually loving her propensity for long showers, giving him a chance for mischief rather than just stopping him from taking a warm shower in the mornings. Skulking forwards, Gearth disappeared into his sister's bedroom, missing the fact that he had a peeping Tom of his own following in his footsteps. Ivy peeked up from the stairs, hunched low with her tail sticking out almost vertical, her natural predatory instincts kicking in as she quietly tailed the cub with a grin, sneaking up to the door and nosing it open just enough that she could poke her head inside. The canine watched Gearth immediately drop his pants and boxers down to his knees as he looked around the room, moaning as he wrapped a hand around his equine pole, his tip already mostly flared as he gave the girth a few strokes, milking a big drop of precum from it. He ran his free hand on Gwen's bed and pillows, picking up one of the plush toys that the girl had sitting on her shelf, grunting as he tried to find something good to really get him fired up. The boy's eyes finally caught the laundry bin sitting in the corner, his hands trembling from a split second bolt of excitement that shot through his spine as he dashed towards it, panting maniacally.

Gearth opened the lid, already catching a whiff of the most incredible scent that he'd ever come across, carefully digging through the basket until he spotted the pale blue panties hidden underneath a few shirts and towels. He pinched a corner of the pair and slowly pulled them out, still glistening and dripping with the older giraffe's honey, the scent of his sibling's heat becoming utterly overwhelming as he dangled the panties right in front of his face. Gearth stared at the underwear for a second before sticking them right against his muzzle, stumbling backwards and collapsing down onto his back on his sister's bed, the springs giving a few squeaks as he huffed her musk, stroking his cock as hard as he could at the same time. Holding back her giggling, the voyeuristic dog spied on him sniffing and licking at the drenched panties, his shafts towering over his belly as he pumped it, the wet slaps of his masturbation intercut with his muffled moans. He could taste his big sister's orgasm, practically hearing her squeals and begs for more as he thrust up into his hand, his balls bouncing up and down with his hips. Ivy's eyes narrowed as she watched the boy's tip flare up to full size, his back arching off of the bed as he whimpered into the panties, letting the taste and scent take him over as he fired shot after shot of seed. The strings landed across his belly and chest, some splattering into his white hair and even Gwen's pillows as he continued stroking, gasping in between his heavy moans. 

Panting with his legs and arms spread at his sides, his dick still pointing up at the ceiling and twitching as the last drops of cum ran down the thick pole, Gearth was exhausted enough to almost fall asleep right then and there, only barely staving off the post-orgasm fatigue mostly thanks to his libido still begging for more. He sat up with a huff, tossing off the panties draped over his snout and wiping off a strand of his sticky love from his cheek, glancing down at the new white stripes he had given his shirt. The cub pushed himself to his feet, taking a second to gather his breath before trying to stuff his cock back into his pants, his manhood refusing to go down even after a thorough release. Gearth finally gave up and just left his shaft out to bob around as he looked at her sister's messy underwear, struggling with an internal debate for a moment before snatching up the pair and tucking them into his pocket, thinking that she surely wouldn't miss a single pair, hoping that the pair might help him get through the rest of the heat without doing something equally stupid again, knowing that the insatiable lust would probably return in just a few short minutes. Ivy spotted the boy starting to leave, quickly dashing behind a corner to watch as he retreated into his own bedroom, hard cock still in hand. Trotting into Gwen's room once the way was clear, the great dane took a closer look at the mess left behind, several stray shots of cum clinging to the girl's bedsheets, one of the plushies lying on the bed left looking like it had been through a bukkake session. Taking a quick taste of the cub's seed, Ivy slowly dragged her tongue across the plushie's creamed muzzle, a wide grin on her face now that she had undeniable evidence of Gearth's interest towards his big sis. Enjoying the thorough scrub, just barely holding back on the urge to dip her hand back between her thighs and ruin the cleaning she'd already accomplished, Gwen turned off the shower and grabbed a towel to dry her wet fur, unsure of where the water began and her juices ended while trying to mop her crotch. She stepped out of the bathroom and walked into her room, absentmindedly humming a tune, only realising something was wrong as he caught a masculine note lingering in the air. She turned around to see Ivy laying on her bed, the streaks of her brother's load soaking into her blanket as the dog smirked, 
"You'll never guess what your precious little brother got up to while you were busy~" 

Gearth stayed hidden in his room for a good few hours, stripped down to the fur as he writhed on his bed, feeling the primal desire gnawing away at him once more. No matter how much he tried, his own hand could only bring him momentary relief, even with the help of his big sister's fragrant panties. By the third hour of hiding out, the boy was starting to feel slightly spent, his throat dry from all of the exertion and his box of wipes for cleaning up his messes already used up. He didn't particularly want to leave his refuge for the risk of running into Gwen, fearing that she would instantly recognise the embarrassing issue he was having, but the need to stock up on drinks and paper towels finally drove the giraffe to step out. He quickly threw on a hoodie and a pair of sweatpants, solving the issue of not being able to comfortably fit his stiff cock into his pants by just tucking it up against his belly with the loose hoodie covering it up, peeking out into the hallway before leaving the comfort of his hideout. He couldn't hear any sign of Gwen or Ivy, hoping that both girls were cooped up in his sister's bedroom as they usually tended to do when they were in heat. Gearth wasn't entirely sure what the pair got up to whenever they'd disappear for hours on end, but it meant that he could sneak around the house without being spotted, which was good enough for him. The cub tiptoed downstairs, careful to not make any noise, constantly keeping his eyes pointed towards the upper floor to see if anyone was coming down behind him. In his haste to make sure that he wouldn't be ambushed from behind, Gearth had neglected to even check what was right in front of him, only realising that both females were sitting in the living room as Gwen cleared her throat, 
"Looking for someone~?" 
He spun around, already trying to come up with some excuse as his hands crossed over his belly, keeping the bulge in his hoodie covered up. His entire train of thought grinded to a halt however as he saw his older sibling on an armchair, completely naked, her knees apart and her equine cunt in full display, sopping wet. On the floor, between the girl's feet, laid Ivy, her back legs likewise spread, her naughty smile growing bigger as she lifted up her tail to reveal her spade, drops of her sweet sap flicking off the wet tail as she wagged it. 

Gearth stared at the two ladies, unable to believe his eyes as they both smirked at him, his sister throwing one foot up onto her seat, splaying her legs open even wider as she laid a hand down on her lower belly, 
"I heard you were poking around in my room a li'l bit ago. Find anything fun in there~?" 
The boy could feel his breath freezing in his lungs as he watched Gwen sliding her hand downwards, sighing softly as she used her fingers to trace her puffy lips, her pink depths giving a wink and letting a drop of her syrup trickle down, the glimmering droplet cascading down and coming to a stop at her tailhole, wetting the giraffe's donut. Ivy hopped up from the floor and slowly strolled towards the cub, letting her body sway in hypnotising waves as she walked past Gearth, nuzzling his leg and rubbing herself on him as she passed, circling around to the other side, 
"Well… it definitely looked like he had a whole lot of fun. I wonder, where did you stash those panties? If I went up to your room right now and sniffed around, would I find them soaked with your cum~?" 
The horrified boy watched as Ivy sauntered back over to the chair, flaunting her pucker and pussy the whole way there, making sure to keep her tail out of the way while giggling, almost feeling his gaze on her flank. Gearth had no idea what was going on or what he was supposed to do, too focused on the heavenly spread on display in front of him to even notice his cock tugging at his shirt, his hoodie pulled up just enough to flash the first few inches of his manhood at the giggling girls. Knowing that their ambush was sure to scramble anyone's head even at the best of times, let alone after letting the boy stew in their scent for some time, Gwen wanted to make the situation as easy as possible to her little brother, spreading her pussy lips open as she motioned for him with her other hand, 
"We both know what you want, so just get over here already and take a taste~!" 

Unable to resist the offer even as he was freaking out in the back of his mind, Gearth stepped forwards and shed off his clothes, zipping down his hoodie and kicking off his sweatpants, letting his shaft flop out as both ladies giggled, Ivy giving her owner a playful nudge, 
"I told you that he was big~" 
Gwen's stare followed her little brother as he walked in front of her, panting and letting his cock drip onto her legs before slowly getting down on his knees, shuffling closer and closer until his maw was only inches away from her slit, the irresistible scent of her estrus driving him wild. Without thinking, the boy dove down into Gwen's cunt, immediately nuzzling his lips against hers, letting her juices run down his chin. Feeling the younger giraffe's long and agile tongue shooting up deep inside of her folds, the teen moaned and grabbed his head with both hands, pressing his snout against her crotch harder, grinding and thrusting her pussy on his mouth as she gasped. With his eyes rolling back in bliss, his face locked in place between his sibling's thighs, Gearth moaned inside of his sister, his dick twitching as he humped the air in his excitement, occasionally glancing against the armchair and leaving big blots of precum stains wherever his rapidly flaring tip touched the fabric. He didn't need to stay humping at nothing for long however, as the great dane laid on her belly and shoved her head down between the chair and him, opening wide to take in as much of his cock as she could, her cheeks bulging out as the equine girth slid halfway down her throat. Only used to her canine companion's stubbier tongue, Gwen finally felt what it was like to have a fellow giraffe eating out her pussy, her screams getting sharper as the cub's assault on her cunt intensified. 

Pushing deeper into his sister's pussy while the feral's throat gripped his flaring tip, only able to get a few tiny gasps of air in between Gwen slamming his face into her slit again, Gearth was in heaven. Before that day, everything that was happening could only ever have transpired in his perverted fantasies, his cloudy mind still half believing that he had simply fallen asleep in his bedroom, but he certainly didn't want the dream to end anytime soon. Ivy tried to take as much of the boy into her muzzle as she could, but she wasn't very experienced with handling males, struggling to get the girthy giraffe all the way inside of her mouth. She had a different plan in mind to stuff Gearth in her however, already feeling the desperate need to fill up a different hole of hers anyway, pulling her lips off of him with a slight gag. The cub felt a rush of cool air as his cock dangled down, dripping with saliva and throbbing. He couldn't look between his legs to see what was happening however, as he was still snout-deep in his sister's cunt, only able to whimper as he suddenly felt another hot and inviting pocket press against his cock, soft and pillowy lips gliding up along his shaft before finally stopping at his tip, the great dane's tail thumping against his belly while he squirmed under his sibling's strong grip. Ivy had her spade lined up with the boy's manhood, her ass sticking up towards his crotch while her head laid against the floor, her claws scratching at the carpet as she backed up and took a deep breath, finally throwing herself against Gearth. He reacted with a muffled howl and a heavy buck into the canine, sinking most of his dick in Ivy's pussy while Gwen's lips gripped at his muzzle, most of his face soaked in his older sister's juices as his balls plopped against the feral's butt. The boy could feel the dog stretching around his cock as he drilled into the yipping and barking bitch, his mouth overflowing with Gwen's sweet drink as Ivy threatened to milk his balls dry, heaving herself back and forth to help the cub breed her fortune cookie. The great dane could feel his tip suddenly expanding deep inside of her, flaring up enough to cause a visible bulge in her belly as a load of warm cream rushed into her, the dog's legs shivering as she grinded her cunt against the boy's base, whimpering happily. 

Watching her feral friend getting creamed under her brother, Gwen was nearly starting to feel jealous, his tongue suddenly not quite cutting it for her. Letting go of his head and finally allowing Gearth to pull his face out from her crotch, the girl stood up, her equine cunt hovering right over his head, still drizzling the younger giraffe with a constant shower of her honey while he gasped and smacked his lips, hunched over because of the incredible grip around his cock. Ivy squeezed as much of the boy's filling from him as he had to offer before going limp, needing a few seconds to catch her breath before she began pulling out, his flare still fighting to keep her hilted as the pair both moaned, a small nudge on her flank finally getting her unstuck. The feral popped free, leaving a trail of cum along the carpet as she stumbled off to the side, laying down with an exhausted huff, almost immediately poking her head between her back legs to clean up the mess leaking all over her thighs. At the same time, Gwen gave her brother a gentle nudge on the chest with her foot, pushing him onto his back, his still-stiff cock snapping towards his head and flinging a few strands of his seed onto his chest as he groaned. The cub looked up to see Gwen standing over him, an almost crazed look on her face as she pumped her fingers in and out of her pussy, her eyes glued to his manhood. Slightly nervous, Gearth held up a hand as he noticed her starting to lower herself on top of him, 
"H… hey! Don't we need like… a condom, or something?" 
Getting down on her knees, stroking her sibling's shaft with one hand and tickling his chin with the other, letting his tip rub against her entrance, Gwen giggled,
"Don't worry, I'll pull out in time, I promise~" 

Gwen made sure to remind her brother of the size difference between the two as she sat down on him, pinning him in place, her slit rubbing on his belly as she panted with lust, her tongue lolling down the side of her mouth, drooling almost as much as her other end. Feeling like he was seeing a new and slightly worrying side of his big sister, Gearth could do nothing but lay still as she groped his chest and pet his cheeks, caressing him with a loving yet very much sensual touch, rising up off of him just long enough to shove his rigid shaft between her thighs and get his tip inside of her. The siblings bleated in unison as Gwen threw herself down the boy's cock, taking his entire length into her warm embrace with a greedy plunge, moaning and grabbing her brother's hands, shoving them onto her tits while she basked in the bliss of his rock hard manhood quivering at the mouth of her womb. Laying on her side and watching the girl ride Gearth like a pony, Ivy began feeling the insatiable hunger building up once more, dragging herself up and crawling over to the boy, surprising him with a sloppy kiss. With a mawful of feral tongue exploring every inch of his mouth and his sister's pussy massaging his girth, the cub let the ladies have their way with him, his tail twitching as he was ravaged and used in all of the best ways possible. Clutching Gwen's thighs, Gearth quickly felt his point of no return approaching, frantically tapping at her feet and mumbling against the frenching canine's tongue as he tried to get her attention, warning her so that she could hop off of him as she had promised. The teen only gave him a devious grin in return however, not even attempting to slow down her thrusts as she moaned out, her tits bouncing up and down along with her, 
"What's that? I can't quite hear you, you're gonna need to talk a li'l bit louder~" 
Growing more panicked, the boy squirmed and flailed around until finally going utterly stiff, his flaring tip pressing right past his sibling's cervix, locking him in for good as he exploded deep inside of her womb, bathing her ready eggs with virile seed as he whimpered, staring into her eyes while gulping down Ivy's tongue. Gwen slowly came to a stop, still swaying around slightly as she laid a hand on her slightly bulging belly, feeling the cub throbbing inside as she huffed, 
"Well… that was fun. Good thing we've got the whole weekend, because I'm nowhere near done~!"
She giggled and glanced over at the great dane's glistening spade, giving the dog a fondle and dipping her fingers inside while Ivy whined into her brother's maw, 
"And it looks like I'm not the only one. I guess you've really got your hands full~"
