Summer had been particularly giddy regarding the next trial as it meant she got to do one of the things she had always wanted to do: fuck a dog and horse at the same time. She had never been in a threesome before, so tonight was meant to be a series of new things for the wandering doberman.
Or at least she hoped it would be.
It was already half an hour past when Raymond and Sally were meant to show up in the park and she began to wonder if they maybe ditched the idea. She withdrew her phone from her pocket and checked her messages for any updates but the only thing that greeted her was the one she had sent to the group chat saying that she was at the agreed upon spot at about 10 P.M.
Summer sighed and looked around at the park that she now found herself in. It was a massive space marked with a winding sidewalk that ran through the park to form a giant X. Several benches dotted the space with large luscious trees and well-maintained shrubs scattered around. She had picked this specific spot because the surrounding foliage made for a perfect barrier to any prying eyes and it was also the farthest place away from the street and any nearby houses, perfect for getting nice and loud like she knew they would be.
Again, she hoped she would be able to get nice and loud tonight. Things looked like they were going to fall through and she was going to have to find some way to get the three of them together like this in such a setting. She feared this was an omen that foretold future hardships for her other trials.
Letting out a frustrated sigh, the doberman shifted the small backpack that she had with her over her shoulder and prepared to disembark the area. Just as she was about to, a pair of figures suddenly appeared coming towards her on the sidewalk. They were unmistakably the husky and horse duo even though the moonlight turned their bodies into swaying silhouettes.
Relief flooded Summer and she excitedly waved her paw over her head as if she was trying to get their attention even though there was no way that they didn't see her. They did return the wave and once they were close enough the one she knew to be the male husky called out.
“Hey! Sorry about the wait, it was a nightmare finding this place,” he half laughed as they came close enough for Summer to get a good look at the couple.
While Sally and Raymond weren't actually a couple, they were well known fuck buddies. She never quite understood why the two never bothered to make it an official thing, especially when they were known to be inseparable before graduation and had been close friends for as long as Summer could remember. It was never really her business so she never bothered to ask. And in truth, all she really cared about was having some fun with them anyway.
Raymond was a tall, athletic husky with a handsome muzzle and gleaming blue eyes. The tight shirt and pants that fit snug over his form accentuated the thick bands of muscle that had been painstakingly grown amid his years as a football player. Despite that, he didn't embody the typical jock mentality, in fact as far a Summer knew he didn't go out for any other sports than just that one.
Sally was a hermaphrodite of equal height to the dog, though not nearly as muscular. She had a proud equine figure that was curvaceous and bold with large breasts and wide hips perfect for baring many foals. Given her sex it was often speculated that between her and Raymond that she was the top and he was the bottom, a rather interesting notion given that she was so nice and not nearly so dominant in social situations. But Summer knew most of all that looks could be deceiving. Her long black hair fell messily around her shoulders and face, even obscuring one eye to leave the other to look at the awaiting doberman with curiosity.
The two towered above Summer as they came to stop side by side just a few feet away. The doberman had to force herself to stay composed or else she might frighten both of them off with her upcoming proposal.
“It's no worry at all, I'm just glad you guys made it,” Summer said back and held her bag tighter to her shoulder.
“So, what's this important thing you had to bring us all the way out here to ask?” Sally asked quickly, though the glint in her eye told that she had some pretty powerful suspicions. Probably more accurate than she realized.
“W-well...” Summer began and quickly collected her thoughts. “I mean...our vacation is kinda going by pretty quick, you know? And we don't really get many opportunities to do really fun stuff before we have to go off to college. I kind of have a bucket list that I'm hoping to get through before the end of August.” As she explained she hoped that she came off as convincing enough. She also hoped that mentioning something like a “bucket list” wasn't too close to violating the rules of the challenge.
“Sure, that makes sense,” Raymond said with a smirk and nodded his head in agreement. “You only get to be eighteen once. Doubt we'll ever come back to this place once the Fall semester starts.” The husky stuffed his paws into the pockets of his jeans and then narrowed his eyes knowingly at the other dog.
Summer felt her heart speed up and her mouth begin to go dry. Something about such a studly husky had her going weak in the knees and she had to remind herself that she wasn't just there to hook up with him and that she had to convince Sally of the proposition as well. Still, it must have had to do with the idea of being bred by him and fostering a litter of strong puppies. But pregnancy was for another time, right now she had a different mission to take care of.
“With that in mind... I was hoping you could indulge me in a rather...unorthodox request...” the doberman nearly whispered.
Sally snickered and looked to her companion who also turned to her. “You really don't need to be so coy, Summer, we're well aware of what you want from us.”
A sudden chill raced through the doberman's body and she swallowed hard. “N-no you don't....” she muttered unconvincingly.
“Oh? This has nothing to do with the Final Days Trials that you're currently undertaking?” Raymond interjected.
Summer's heart dropped into her stomach and her ears fell flat against her head. So early into the challenge and her first major hiccup happened at number three. This was going to require some pretty major reconstruction of her plans if she hoped to salvage her end total.
“You're kidding me,” Summer groaned. “How the hell did you guys find out?”
“Oh please, like it wasn't easy to figure out,” Sally laughed. “How normal do you think it is to ask two classmates out here in the middle of nowhere? Whom you've barely hung out with outside of school? Who happen to have a unique relationship?”
“God damn it,” the doberman sighed. “Well, there goes that I guess.”
The husky and horse shared another look, this time of confusion. “What do you mean?” Raymond asked.
“I can't count the trial towards my goal if you go into it knowing what I want. Not that I assumed it was guaranteed to go that way,” Summer quickly explained. “But, you're right.”
“That doesn't sound quite right,” Sally replied.
“Yeah, you've got that part wrong. The trial is only considered void if the one initiating it informs the others of their intention. If it's the other way around then everything is fine,” Raymond added.
Summer furrowed her brow and cocked her head. “That...can't be right.”
“Check for yourself. You have the book with you, right?” Sally asked.
The doberman chewed at her lip as she mulled her situation over for a couple seconds, fighting with herself with what she wanted to do. In the end, she decided it couldn't hurt to check. She withdrew the bag the hung from one shoulder and opened it up to produce the notebook and flipped it over to the rules page.
There weren't many of them to read over so finding the relevant one was easy and it wasn't very long at all. She read it over in her head first and then paused in confusion. She read it again and her eyes gradually grew wide with realization. “ 'Whoever undertakes these trials may find it to be good sportsmanship to avoid informing their fellow participants of their intentions until after the trial has concluded. Doing the opposite will result in a failed trial and no awarded points',” Summer quoted verbatim.
“Seems about right to me,” Raymond said with a confidant nod.
“So... this is all still legal?” The doberman asked excitedly.
“Absolutely,” Sally concluded.
“With that in mind, which trial were you looking to undertake with us?” The husky pressed.
Summer blushed and laughed to herself, her hope for the situation renewed, she felt giddy once again. “I don't think I can say, otherwise I really do think I'll void the trial. Do you think I could ask for you both to trust me?”
“I don't see why not,” Sally replied.
“Can you at least tell us what you want?” Raymond added.
“Well, that part should at least be obvious. I just need you both to fuck me out here in the park. And the sooner we do it the better. Every second out here we risk getting caught,” Summer said quickly.
“Right to the point, I love it,” Raymond said and began approaching the doberman. As he did, his paws drifted to his pants and he began to undo them. By the time he got to her, the button was popped and the zipper pulled down to reveal his underwear beneath and the sizable sheath that resided within.
Summer quickly stuffed the notebook into her backpack and cinched it shut by the time he was close enough. Despite her eagerness for the situation and to indulge in her more carnal desires, she wasn't going to make it easy for him. She smirked and backpedaled away until she butted up against the nearby bench and dropped to its seat.
Raymond eagerly followed, but by that point he wasn't alone. Sally trotted up casually behind her friend but she was in a much more advanced state of undress. She had since completely taken off her bottoms and now walked bottomless towards the doberman, her thick equine cock swinging from side to side with every step.
Despite Summer's natural affinity for dog dicks, she couldn't deny the beauty that came with something from a horse. Sally was the first to corner the doberman and push her limp shaft out to her like it was a prize she needed to take. In a way it was, and she was all too eager for it.
Not wanting to be shown up, Raymond made sure to finish undressing before he came up beside the hermaphrodite. Unlike the horse, he decided to take everything off so that nothing obstructed his powerful physique from the admiring gaze of the other dog. To his pleasure, Summer's eyes widened and she shifted against the bench in a way that told him how hot she was getting for a taste of what he had to offer.
Unfortunately for him, she was currently tasting something else at that moment.
Not wanting to waste what little time they might have, the doberman had taken Sally's offered member by the tip and greedily pushed as much of its soft length into her mouth. She washed it back and forth with her tongue, happily murmuring to herself as she sampled the salty essence of what had to have been a recent climax that hadn't been washed off. She was, of course, more than happy to be a cock cleaner for anyone as beautiful as Sally.
The hermaphrodite moaned under her breath and tilted her head up as the growing pleasure came on. Blood rushed between her legs and began filling her length as the doberman drew a stronger vacuum on the shaft while slathering its spongy flesh in saliva.
One of Summer's paws lifted from its place at her side to grope and fully appreciate the hanging sack right below her chin. She could feel how heavy those luscious orbs were and how eager they were to dump their load. She wanted to tell them that it would happen in due time if not for the steadily swelling horsecock between her lips.
Though the doberman was entirely occupied with pleasing the horse in front of her, Raymond made himself known as he gradually touched himself into an excited frenzy. His thick sheath swelled with his growing cock and eventually drew back to reveal the sizable red shaft. It glistened in the moonlight with a fresh layer of precum and emitted a scent that immediately caught the woman's attention even though her senses were already filled with Sally's smell.
Summer's free paw reached out and wrapped around the pulsing dogcock and felt how incredibly hot and hard it was. So eager to mount and get her pregnant, it would seem. Too bad for his more feral instincts, she had her life planned out well into the future. On the bright side, it meant that he was going to get to have her ass when the right time would come.
For now, the doberman had to juggle the amorous couple.
She gradually pulled off the semi-rigid horsecock with a loud slurp and smack of her lips, its own flesh shining with a thick layer of saliva. She relinquished her hold of Sally's balls and began pumping the shaft from base to tip as she pivoted to the husky's lap. She opened her mouth nice and wide while angling his tip down and sank him all the way in with one motion.
Raymond groaned and reacted by placing both paws on the sides of the woman's head. Her lips kissed his deflated knot and his tip sank a couple inches down her throat, though luckily not far enough to cut off her breathing. That didn't stop her from trying as she began to bob her head aggressively right from the start.
The taste of a fellow canine with as strong of a genealogy as Raymond's had her body going into over drive with fresh arousal. She could practically taste the kinds of pups they could make and how strong they would be. The more that her tongue stroked the underside of his dick the more she began to imagine a future of them together in some sort of idealistic lifestyle. Like a perfect nuclear unit with a pair of hybrids running around a fenced in yard.
Her pussy ached with need just from thinking about it, but she knew that she had to remain vigilant. As badly as she wanted to feel his cum in her cunt and the bulge of a swollen belly by the time she got to college, there was just no way she was going to allow it. Besides, she was already on birth control, even if she decided to risk it there wasn't a very good chance of conception happening. Some part of her baser animalistic side growled internally and she had to tell it to shut up and to just enjoy the ride for the time being.
Summer timed her breaths and tongue strokes with the sway of her head. Her expert technique had the husky moaning eagerly for more and holding the sides of her head even tighter. He soon began to push his hips forward to meet her mouth while pulling her down in tandem with her movement. Mere second later and he was practically skull fucking her without mercy.
She was content to reside herself to this role for the time being. She slackened her jaw and concentrated on keeping a consistent pressure against his cock as it pounded between her lips so fast that his hips became a blur. All the while he took full advantage of her mouth, not once did she relent on vigorously pumping over the hermaphrodite's shaft that had now grown to its full size and stood tall from her lap.
“Stop hogging her, mutt,” Sally snapped playfully and shoved her shoulder into his. It was effective enough to knock him off balance and slow his thrusting to a fraction of what it was, but he still kept at it.
“I'm not done,” Raymond said back through grit teeth. He gradually closed his eyes as he built his speed up once more.
“Fine, then I'll just use you to keep myself ready,” the hermaphrodite retorted and pulled away from Summer's grasp to step up behind the husky.
“Wh-what?” he yipped in dazed alarm as he slowly registered what she said. By the time he turned his head to follow her she had already oriented herself at his back and smacked his ass with her throbbing pyre. “H-hey, get away from there!”
“Sorry, doggy, I gotta stay warm somehow,” she laughed and angled her cock down to nudged it under his tail and between his buttcheeks. He gave a startled bark but he didn't dash away like many other men might have done, instead staying right where he was and fucking the doberman's mouth.
Sally's flat cock tip eventually brushed against his pucker and popped inside with a quick buck that made him gasp from a mix of sudden pain and pleasure. Once comfortably in, she grabbed him by the hips and eased the rest of her girth into his clinging depths until she her balls were touching his.
“Fuck, never get tired of feeling that,” she whispered into his ear with a grin but just loud enough for Summer to catch it. The doberman couldn't believe that the rumors were true and it somehow made her even hotter to know something that many others likely didn't.
“You could have at least used some lube,” the husky grunted as he felt the hermaphrodite draw back and push in, the start of a gradual bucking tempo that would have her going from base to tip in his ass.
“I would have if you weren't hogging the girl that was providing it,” the horse retorted smugly and pressed her breasts against his back. The roll of her hips translated through his own to push his cock as deep into Summer's mouth as it could go. With her interjection, the three of them fell into a consistent rhythm that had the couple moaning loudly while the doberman was forced to stay quiet.
Caught in the middle, Raymond was subjected to the blissful sensations on either side of his hips. Each time the herm would push in, his body would clamp down hard and make his cock flex in Summer's mouth. The grind of the fat length against his prostate had precum springing from his tip to paint the woman's tongue in sticky essence.
Sally's arms wrapped around his midsection as she began to pound him even faster and harder. Her shaft indented his ab-rippled stomach with every motion and make him howl out in carnal bliss. She couldn't help but grin as she stared lovingly at the strong dog that she was able to dominate so easily when it suited her. It truly was too bad that he wasn't the type to take to commitment, but she was steadily wearing down that part of him.
“F-fuck, I'm getting close,” Raymond groaned and pushed his hips more aggressively to meet the doberman's mouth.
Upon hearing him, Summer immediately struggled to pull off his dick while she shoved against his legs. It was a bit of a battle given how strong he was, but as soon as he realized what she was trying to do he let go.
“You can't cum in my mouth!” Summer gasped as a mix of precum and saliva oozed down her bottom lip. Sally slowed her thrusting to peer around the husky at the other dog, waiting for an explanation. Once the doberman caught her breath, she continued. “I need you both to fuck me at the same time, you can only cum in my ass or pussy.”
“Is that so?” Sally laughed and slowly pulled back, her cock popping free of the husky's backside with a loud slurp. He groaned in relief and despair as he wasn't quite ready to be done getting fucked, but he was more than happy to be the one delivering now.
“Where do you want us?” The husky asked.
“I want you on the bench,” Summer said and pointed behind. Raymond followed her finger and complied without another word, plopping down on the wooden seat beside her with his throbbing cock continuing to stand and beg for attention.
“And me?” Sally asked as she came to stand right beside the doberman. As she did her cock hovered close to Summer's face, allowing her to get a good smell of the pulsing flesh. She immediately recognized the scent of what had been on the member when she first had a taste of it and smirked at the thought of the two having a quicky in preparation of what they knew Summer was going to request of them.
“You get to be on top,” Summer replied as she stood up for the first time in fifteen minutes. As she did, her paws went to her pants and quickly undid them so she could shove them down to her feet, underwear and all.
At first glance, Sally giggled at the thick tuft of black pubic hair between the woman's thighs and found the sight to be a rather attractive one. “Oh my, I bet you're never cold in the winter,” she commented and bit her lip.
“Nope, and I save a ton on razors,” Summer laughed back and winked at the herm as she maneuvered over to Raymond.
The husky was equally as enamored by the woman's pubic hair though he made no comment about it. In fact if Summer wasn't mistaken he looked hungrier, like he'd have much rather preferred to return the oral favor she had given him instead of getting to enjoy her ass. Perhaps sometime in the future she would let him indulge in such an act, but for now they had more important things to do.
Summer turned her back to the other dog and positioned herself between his legs. She lowered her hips to his lap and reached beneath herself to grip his cock and guide it to her wanting ass. As much as her body begged her to reconsider its choice of where to put him, she continued on and let her weight take him into her tight bowels.
Raymond moaned under his breath and pushed up to meet her backside on reaction of feeling his entire length get taken in. Once she was sure of his insertion, she let go of his dick and leaned back with both paws on his stomach. She didn't stop until her body nestled against his chest and the only thing that protruded from her ass was his swollen knot.
Once she was in her preferred stance, Sally stepped in to complete the arrangement. With one hand on her cock and the other holding Summer's legs open, she set her semi-flared tip to the hairy pussy and pushed in like she had with the husky's ass.
As tight as the doberman's insides were, with two dicks in her at once she grew all the more tense. All three groaned as the herm didn't stop until she was as balls deep as her companion. With a slight squirm of adjustment, the three were ready to pick up where they had left off.
Summer raised her arms above her head and reached back to hug around the husky's neck as he began to thrust up. She set her feet on his knees to give some extra leverage to the action but it didn't last long when Sally pushed her hands under the woman's bent knees and lifted her to the point that she was curled in on herself.
The herm leaned in close as she began to pump her hips in tandem with the husky's. The smack of their bodies crashing together fit well with the growing sounds of pleasure that emanated at a constant rate.
Amid their mutual fun, the doberman looked down at herself and was pleased to see the prominent bulge through her stomach of the double penetration. It was so rare of a sight for her to enjoy given her limited experience with horsecock, let alone two dicks at once, but that wasn't all she was content to see.
Without warning, Summer's paw shot out and grabbed a hold of the herm's shirt and harshly yanked it up over her breasts. Sally didn't mind, and in fact encouraged it with a slight shift of her upper body. Once her huge mounds were free of the covering and her ebony nipples swaying with her rapid bucking, the dog thought it fit to grab a hold of one and squeeze.
Not to be outdone, Sally tugged at the side of Summer's own shirt until it too was nearly over her head. Though the horse's was nearly twice as large, the sight of the dog's perfect curvature was one that she desperately needed to admire. Despite that, she never faltered her movements and even pressed more of her weight behind every strike.
Even though their fun had only just begun, Raymond's nearing climax was quick to show itself once more. It came first as a hitched grunt from the husky and then his shaft flexed extra hard with his hefty bulb growing in size.
Summer could feel it each time it would slam against her already stretched pucker as it was desperate to lock them together. She was just as eager to feel him swell inside but wasn't convinced it was going to happen. His cock was already far above average as far as dogs went, and his knot was as large as a softball already. At its maximum it would be even thicker than Sally's cock at the base.
Though somewhat sad that their fun was going to end mere minutes after getting both holes filled, she was nonetheless happy to have another finished trial on record.
The doberman's body rocked against the rutting cocks as they moved at irregular intervals. She was entirely out of control and at the mercy of her lovers as she barely had any leverage on Raymond's lap, especially with her legs in the air like they were. It seemed to be the exact place that they preferred her to be though.
The husky's oncoming climax wasn't the only one that was ready to be released, however. Through all the excitement, Sally was teetering on that same edge and as time wore on she progressively telegraphed it with greater neighs and more vigorous thrusts. She bottomed out as hard as she could manage like she was trying to get Summer pregnant as well. Luckily no amount of horse cum would accomplish such a thing, but that didn't keep the doberman from wondering what their own kids would look like.
“Ugh, come on!” Raymond grunted as he clamped both paws on the woman's hips and yanked her down on his cock as he'd thrust up. The sudden outburst caught the herm's attention and she grinned knowingly.
“Having some trouble there, stud?” Sally asked playfully.
“I can't get my knot in,” he growled deeply while clenching his teeth.
“Poor boy,” The horse moaned and reached out to place both hands on Summer's shoulders, making her look up to see what the herm was planning. She didn't have to wait long for an explanation. “Let me help.”
With that, Sally suddenly shoved down as hard as she could just as the husky thrusted up. An intense pressure the likes that Summer had never felt before filled her asshole and made her think that her stretched pucker was going to tear. She opened her mouth to yelp her opposition to what was going on, but before she could their combined effort paid off.
With a triumphant grunt, Raymond's gigantic bulb popped inside of the doberman's ass and effectively locked them both together. Even with a horsecock still fucking her cunt, she had never felt nearly this full. It was compounded by the immediate deluge of dog cum that began gushing into her bowels.
Raymond's exerted grunt turned into an ecstatic howl as the intense pleasure crashed through his cock. As much as he tried to keep pounding her, there was just no room for it. For the next thirty minutes or so, the doberman was cemented to his lap and entirely at his mercy.
Sally didn't seem that perturbed by this fact, as she saw it as an opportunity to truly go all out. She leaned all of her weight against Summer's front and began rocking her hips as fast and hard as she could. Her swelling cock rubbed against the thin veil of flesh that separated the doberman's pussy from her ass and she could feel the unmistakable indent of dogcock from the other side.
To summer's immediate pleasure, she could feel the unmistakable flare from the equine shaft and was glad to know that this trial was truly living up to its name. She only wished that it could have lasted longer for her own orgasm to reach its peak, but the fond memories of these final moments were going to live on well into her time alone later.
The herm nickered and huffed as she neared her end and finally whipped her head back to let out her loudest neigh yet. When she did, Summer's cunt flooded with the thick, viscous cum at such an incredible volume that she felt her womb get filled to the brim right away. Sally buried her whole shaft on that final thrust with nothing left out but her draining balls.
Each gush was palpable for both dogs as the thick stream spilled out around Sally's member and splashed down the front of Raymond's sheath and balls. Her prolonged moan died down when her cum was just a trickle and her cock began to shrink. After a few more moments of her straining against Summer, the herm finally relaxed her form and settled back.
Sally's flare made disembarking from the woman's pussy slightly difficult but she popped free with a loud slurp. The doberman's gaped hole then spewed all that was kept inside which made her sigh with pleased relief but also mild sadness that she now felt so empty. It was still all right given that Raymond's massive dick and knot where sure to keep her at least partially filled.
“Satisfied?” Sally asked as she stepped back to admire the sloppy mess that had become of the doberman.
“Oh yeah,” Summer laughed and reached back once more to pet over the husky's cheek. He turned his face into the gestured and nuzzled affectionately into her palm. “Think you could hand me the notebook? I'll need both of your signatures if you don't mind.”
“Of course not,” Raymond barked happily and leaned down to bury his nose against the nape of the woman's neck. She laughed and tried to squirm away but found herself effectively anchored in place.
Sally happily retrieved the doberman's bag and pulled the notebook from it. As she came back to the two others, she flipped it open and thumbed casually through the various entries from past people that had undergone the challenge. When she got to Summer's entry and detailed notes, she took her sweet time with reading through all that was there.
“Ah, the 'knot and flare' challenge,” the horse laughed and quirked a brow as she looked at Summer's currently stuck state then down at her own half-naked self to see her cum smeared cock dangling between her legs. “Yup, seems to check out.” She nabbed the pen that was stuffed into the spiral wired spine and popped the cap off. She signed her name next to the challenge like the entries before and then handed it over to Raymond.
“So...” the herm began with a knowing smirk. “Miss Woodson, eh?”
“Heh, yeah,” Summer laughed with a slight blush coming to her cheeks.
“What was she like?” Raymond asked as he quickly signed his name beside Sally's and then handed it down to the doberman.
“Oh, she was lovely,” Summer said nonchalantly.
“And? What else?” Sally pressed.
The doberman shrugged and offered an apologetic smile. “It's kind of a long story.”
“You're not gunna be going anywhere for a while,” the husky retorted and gave his hips a slight shift to emphasize the cock that still stirred her belly.
“Fair enough,” Summer conceded and bit her lip. “Well... she was in her office one day...”
