Genes of powerful hybrids ran in Xavier’s family, so it hadn’t been a surprise when the doctor had announced that the boy would grow up to be a hybrid himself. The CEO of Philo Inc. had excitedly consulted various experts and had his firstborn’s fortune told numerous times, and each time he had been told that the boy would grow up to be a strong, fierce leader. A tiger or a wolf most likely, fit to represent the billion-dollar company like generations of men had before him.
Xavier himself had minded little when on his 16th birthday he had woken up with a pair of long ears and a fluffy tail. His countless hours of physical training under private instructors or his straight-A record from his elite boarding school hadn’t been affected by his newly found identity in the slightest. His classmates would certainly have liked to knock him down a peg or dozen, but each of them had found out quite fast that their own beastly genes alone were no match for years of discipline and hard work.
But no matter how many classmates Xavier proved wrong, it was never enough for his father. By his 18th birthday Xavier had had enough of the disappointed look in his father’s eyes, and instead of opting for a plastic surgery his parents had oh-so-subtly hinted at, Xavier left his family home and never looked back. If his family wouldn’t accept him, he would find people who did.
To say his wish had been granted would have been an understatement.
”Xa- Xavier, ahh—”
Xavier grits his teeth as he tightens his fist in your hair. His other hand on your hip is struggling to keep its hold on your sweat-slicked skin as he fucks into you. He lowers his head to mouth your neck as he feels you getting closer to your third orgasm, and you whine as his cock presses ever deeper into you. The smell of your vanilla body lotion makes him heady, and he can’t help nipping at your warm skin as he pushes the both of you closer to the edge.
”That’s it, Starlight,” he says and winds his arm around your waist, pulling you impossibly close, ”say my name, louder ”. Your eyes roll to the back of your head as you comply, his name escaping your lips in a pitiful whine.
The slapping of skin against skin gets even louder. Mixture of his earlier releases and your own essence escapes your womb and gathers around your entrance, a sight so filthy it would surely make Xavier cum on the spot if he had the willpower to peel himself off your back. Yet he merely cradles you tighter, pushing your face against the mattress as his shallow trusts bully your sweet spot almost torturously fast.
Him turning out to be a bunny-hybrid instead of a fierce predator had had little effect on his intellect or his combat abilities, but once he had found his pack, someone to share his intimacy with, Xavier had discovered that there were indeed aspects of his nature that separated him from the others.
Such as the call of the breeding season, or his rut , with all its perks and drawbacks.
The perks? Seemingly infinite stamina with no refractory period whatsoever.
”Going to fill you up again Starlight, can you feel it?”. You instinctively tighten around him, every muscle tensing in anticipation.
”That’s my girl, taking me so well. You are so full of my cum already, aren’t you?” Xavier caresses your stomach with tenderness that doesn’t match the brutal pace of his hips, and as he presses down on your womb you feel cum gushing out of your pussy, adding onto the mess between both of your hips.
”F-fuck, Xavier, so close, don’t stop, please .” You begin to shake, and Xavier slips his hand downwards, teases your oversensitive clit as he bites down on your neck. His cock pulses deep inside you, and soon you feel the warmth of his cum filling you up again. You sob against the mattress as another orgasm is wrenched from your body, leaving you boneless and out of breath under your lover.
When Xavier and you first met he couldn’t believe a person like you could exist: a human with Resonance Evol that she had harnessed to harmonize with all manner of different hybrids. Ever the persistent mediator, your goal originally had been mastering the art of conflict resolution between humans and hybrids, something you had been diligently studying in the university where Xavier met you. However, as him and the rest of your pack had found out, your Evol had also made you more… receptive and durable than the average human. Shared among half-human hybrids and one merman you weren’t much phased by their intense and often physically intimidating mating habits.
But the drawbacks of Xavier’s rut were the same as its perks, and thus even your enhanced capabilities had their limit.
Xavier kisses along your neck and spine as he pulls out, earning him a tired mewl in response. He sits up and rubs your butt gently as he watches his release slowly spill out of your swollen pussy. He isn’t the gentlest lover on an average day, and his rut makes him downright feral. The sight of you being stuffed to the brim with his cum doesn’t exactly help with his self-control, either.
Xavier pushes his thumb into your sopping cunt and licks his lips as more white spills out, trailing along your shivering skin. His cock twitches against his thigh, and he almost absent-mindedly starts stroking himself. His thumb pushes further into you, and that is enough for you to snap out of your post-orgasmic bliss.
”Twinkle twinkle,” you groan and shift your hips away. Xavier instantly pulls his thumb out at the sound of your safeword and lays his palm on your butt instead.
”Sorry princess,” he murmurs. You curl up on your side and lay your own hand upon his.
”It’s okay Xavi. Would if I could,” you smile tiredly at him. ”It makes me sad too to see you like this and not be able to help you.”
Despite the lack of stimulation Xavier’s cock is again fully hard, a sticky mess against his muscular leg. Xavier keeps running his hand up and down the shaft, but he knows it’s a futile effort. Once he is deep into his rut he can’t truly be satisfied by anyone else but you, and your packmates.
Your packmates such as the hulking giant of a dragon-hybrid, who now knocks on the bedroom door before entering with two glasses of water.
”Sounded like you two are finished,” Sylus says with a lazy smile as he walks up to the bed. You thank him for the water and gulp it down greedily. Sylus hands the other glass to Xavier, who thanks him while avoiding meeting his gaze head on. Sylus isn’t deterred and instead lets his gaze roam over both your naked forms, unabashedly enjoying the erotic mess you have made of one another.
”How are you doing?” Sylus asks as you hand the glass back to him.
”Blissful, as always,” you sigh and flop back onto the mattress, ”but I don’t think I can continue further. Even if…” you trail off and turn to look at Xavier again. Xavier’s eyes are fixed upon you in favor of ignoring Sylus, who is looking amused by the bunny-hybrid's predicament.
”Rut still hasn’t gotten easier for our bunny? You should be lucky yours only last for a couple of days, unlike our mermaid’s heat cycle.”
Xavier finally turns to Sylus to cast him a withering look, but his resolve crumbles embarrassingly easy as he lays his eyes on his taller lover. Sylus is wearing nothing but a black silk bathrobe and matching black underwear, both of which do nothing to hide the outline of his arousal. His long tail swings lazily behind him, and his black horns shine in the dim mood-lighting of the bedroom.
Dragon-hybrids are notoriously possessive and territorial, and Sylus is no exception. His self-control in terms of sex is par none, but that doesn’t mean he isn’t struggling with the scent of desire that now permeates half of their shared home, courtesy of Xavier’s rut.
Sylus bends down at the waist to meet Xavier’s gaze head on. He takes the empty glass from the blonde and then places his index finger under Xavier’s chin, lifting up ever so slightly.
”Do you need my help, bunny?”
Xavier’s first instinct is to deny Sylus. Getting intimate with you had been easy since the beginning: they all had been borderline obsessed with you, so desperate for your affections that they had been willing to share you for it hadn’t been an option to stay away either. Getting intimate with each other had been, well, a bit more complicated. Even with your Resonance Evol there had been many boundaries to agree upon and many difficult discussions to endure before they had settled into this beautiful mess of a pack dynamic. A dynamic where you were the absolute leader, whether you realized it or not.
The rest of the hierarchy shifted as fluidly as sand in an hourglass, molded by their respective heats, ruts and other hormonal cycles as well as countless other factors. And it just so happened that Xavier naturally gravitated toward the more dominant role in the bedroom, with you but also with his other packmates. He liked to think that his background played no part in this, but the way his sharp, silent commands and muscles honed to perfection kept you in a short leash begged to differ.
He wasn’t overcompensating, that much was certain. It was just… easier to hold the reins himself most of the time. This rut was not one of those times.
You grin as you push yourself backwards on the bed, making more room for the men. Neither of them seem to notice as Xavier slowly sits upright and Sylus places one knee on the bed. Xavier’s chest rises and falls in sync with his deep breaths, and his cock bounces against his taut stomach. Sylus’ red eyes are fixed on him, dark with lust and affection, and his tail slithers onto the bed and around Xavier’s hip.
”You need to use your words, Xavier,” Sylus drawls as he plays with the knot of his bathrobe. Xavier’s eyes dart up and down the dragon-hybrid’s body as his self-restraint fights a losing battle. Sylus’ tail slides up Xavier’s spine, and the blonde draws a shuddering breath before swallowing harshly.
”Please,” he finally says, ”I need…more.”
Sylus’ grin widens and his pupils blow out until his irises turn completely black.
”Present yourself to me,” Sylus demands as he opens the knot of his robe and shrugs it off.
A strangled moan escapes from Xavier who falls onto his back and hooks a hand behind his thigh, spreading himself before Sylus. Sylus’ chuckles rumble in his chest as he strokes himself through his underwear, praising his lover in a hushed tone.
You sigh happily as you feast your eyes on their perfect forms. Your own arousal tingles in your belly, faint but painfully insistent. You are never left wanting in bed, and precisely because of that it is rare for you to just watch your packmates without really participating. Even more rare is to see Xavier being stalked like the prey-animal his genes determined he should be, something that would be concerning if it was anyone other than your mutual packmate doing the stalking.
Sylus bends down to open the drawer of the bedside table and pulls out a bottle of lube from there before climbing onto the bed with Xavier. The blond man waits for Sylus’ next move, his impatience betrayed by his darting eyes and shallow breathing. Sylus coats two fingers in lube and grabs Xavier’s raised leg by the ankle with his free hand.
”Has it been a long time?” he asks as he circles Xavier’s hole. Xavier sucks in a breath through his teeth and nods. Sylus focuses his eyes on Xavier’s face and slowly pushes one finger inside.
”Breathe, bunny.”
Immediately Xavier’s eyes screw shut, and he starts breathing slow and heavy. His hands fist around the sheets, not sure where to grab onto. Sylus turns to you and nods towards Xavier with a smile.
”You can help him relax, sweetie. Soon he will get impatient and start to demand I fuck him only half-prepped.”
Xavier opens his eyes ready to retort the dragon-hybrid's words but is cut off by Sylus’ finger curling into his prostrate. Xavier lets out an uncharacteristic ’fuck’ and Sylus adds a second finger as Xavier is distracted. You scoot over to Xavier’s side and stroke his stomach, easing the tension that’s built up there. As you feel him relaxing under your touch, you trail lower and curl your hand around Xavier’s cock. He throws his arm over his eyes and whines, and his other hand reaches for your head that slowly lowers onto his swollen member. You taste your combined essences on him, a strong and addicting flavor that you crave more the deeper into your mouth you take him.
You hear rather than see Sylus add a third finger as Xavier’s whines turn into incoherent babbling. You push down at the root of his cock as Sylus fingers him with increasing speed, and soon you feel his cock swelling in your mouth.
”Already?” Sylus hums as Xavier tightens around his fingers, the mean undertone in his words only pushing Xavier closer to his climax. ”Better hope this isn’t the last one you are giving me.”
You are lucky you have learned the telltale signs of your lovers’ impeding orgasms as Xavier’s hits him like a freight train with you pulling back at the last possible moment as not to choke. Still it fills up your mouth and escapes down onto your chin as you gasp for air. Sylus releases Xavier’s leg to grab your head and pulls you in for a messy kiss, taking his share of Xavier’s cum. When you part his lips are glossy and tainted white.
”You taste heavenly, little princeling.”
Usually the term makes Xavier bristle, but now he barely has the mental capacity to rise onto his forearms to catch his breath before his arousal is stirred up again. Sylus slips his fingers out of Xavier and hooks them under the waistband of his own underwear.
”Safeword?”
Xavier shakes his head, and Sylus takes it as a permission to continue. He slides down his underwear and his cock slaps almost violently back up to his abdomen. Its dark, hard skin matches Sylus’ horns, and its girth is the inspiration of the many fantasy dildos you owned before you experienced the real thing. You sigh wistfully at the sight even as the dull throb of your pussy reminds you that you have had your share for tonight.
”I’m so jealous, Xavi,” you whine playfully as you scratch your blond lover at the root of his furry ears, ”when Sylus fucks me it feels like he’s reaching my soul with that cock.”
Because while all your lovers are more than well-endowed, Sylus has always been in a league of his own. You all know he is endlessly gentle and patient when making love to you, but it’s still always intimidating to see him in his full glory. And despite of that Xavier crawls towards him on all fours without hesitation.
”You sure about this bunny?” Sylus asks as Xavier lolls his tongue out and places kitten licks on the reddish tip. Sylus’ cock feels white-hot on Xavier’s tongue, courtesy of the dragonblood pumping through his veins. Xavier ignores Sylus’ question and closes his eyes, lips wrapping around the cockhead as he lets his mind turn on the autopilot.
Sylus sighs and pets Xavier’s head while you coo praises into the bunny-hybrid’s ear, scratching it again in a way that you know makes Xavier’s cheeks heat up. Sylus’ tail coils behind Xavier, and the hard scaly tip rubs against Xavier’s hole, making him whine around Sylus.
When Sylus decides the smaller man has had his fun and pulls Xavier off his cock, he is met with a gaze of cloudy azure blue, beautifully accentuated by the rosy cheeks underneath. Sylus taps his cock once more on Xavier’s lips and tightens his hold on Xavier’s hair enough to make his lover focus.
”On all fours. Place a pillow under yourself.”
The reality settles in again and Xavier blushes dark crimson as he hesitates for a moment. Sylus raises a single eyebrow at him and you tsk in mock disappointment.
”I thought that was your favorite position, Xavi.”
It is, and that’s why he knows just how deep inside you he can reach. Xavier is painfully hard, but he can’t help his limbs from shaking as he moves into position. You brush the blond strands from his face and stroke his lips with your thumb.
”You know Sylus won’t hurt you, right?”
To emphasize the same point Sylus bends over Xavier, his cock resting on Xavier’s rear, and turns Xavier’s face gently towards him for a kiss. On instinct Xavier ruts against Sylus, his small tail perking upwards to give even half an inch more room for the dragon-hybrid to mount him. Sylus winds his arm around Xavier’s upper chest and nuzzles his neck, much like Xavier had done to you earlier.
”Relax for me, love.” And then he starts to push in.
You swallow Xavier’s moans and hiccups with your mouth and rub his scalp as Sylus sinks in inch by inch. His replaces his arm around Xavier’s chest with his tail and spreads Xavier’s ass cheeks wider apart with his hands. He watches in silent awe as his blond lover takes him in, stretching to his limit. Soon it is impossible for Sylus not to rub against Xavier’s prostrate, and the bunny-hybrid starts rocking his hips against the pillow.
”He’s in so deep, princess,” Xavier gasps against your lips. ”I’m—I’m gonna…”
”Not yet Xavi, he isn’t even all the way in yet,” you tell him and wipe away a stray tear from his cheek. ”You are doing so well for Sylus, such a sweet little bunny.”
Xavier keens from the praise as Sylus finally bottoms out. Sylus growls as he lowers himself flush against Xavier’s back. He starts to rock back and forth minutely, and you release your hold on Xavier, giving him another pillow to hug as Sylus’ weight pushes his upper body down into a mean bend.
”Such a tight little bunny,” Sylus groans as he places his other hand onto the nape of Xavier’s neck, ”so hot, so perfect. Tell me, will this be enough to satisfy your rut?”
Sylus punctuates the question with sharp, shallow thrusts that make Xavier sob into the pillow. His legs keep trying to spread more apart, his poor tail shakes as his body struggles to accommodate all of the cock he is given. He feels so full , so complete, so---
Then Sylus’ hand tightens around his neck, and the next thrust on his prostate makes stars explode in Xavier’s vision. His comes into the pillow below without a warning, his body jerking violently. Sylus grits his teeth as Xavier tightens around him, keen on making him cum on the spot as well. Sylus slows down his pace but doesn’t stop completely. Instead straightens up onto his knees and pulls Xaviers hips flush against his, making his lover scramble for purchase with his forearms.
”Not enough,” Sylus rasps, ”how many times you made her come tonight? Four?”
”Only three,” you muse as you lean back against the headboard, enjoying the show your lovers are putting on for you, ”but maybe you should aim to top that.”
Xavier shakes his head but makes no move to wriggle away from Sylus, nor does he utter a single coherent sound as Sylus picks up his pace. He holds Xavier under him like Xavier had done to you, his massive frame towering over the bunny-hybrid who can do nothing more than take, take and take. True to his word Sylus doesn’t stop when Xavier comes for the third time, completely untouched and drooling onto the pillows. He does pull his blond lover up against his chest, holding Xavier up and open with his tail and other arms, while his free hand cradles Xavier’s jaw.
Your arousal comes back with vengeance as you gaze upon Xavier’s wrecked state, his poor cock still half-hard as his eyes struggle to remain open. Sylus pushes his thumb into Xavier’s open mouth and the blond sucks on it with a pitiful whine.
”Has our bunny finally been fucked silly, hmm?” Sylus chuckles breathlessly as he tries to fend off his own inevitable orgasm. Xavier has loosened around him and is beautifully compliant when Sylus kisses him. Sylus delights in the small ‘ah-ah’ sounds that Xavier makes as his prostrate is mercilessly bullied by the inhuman cock.
As Sylus ends the kiss he notices you writhing in your place, and sighs as he sees you pleasing yourself with your fingers. Xavier must see it too, as he licks his lips and whines in a high pitch only reserved for his ruts.
”How about next time you think ahead, and ask one of us to join you from the start. Wouldn’t it feel good to be taken at the same time as you take her? Or maybe you’d prefer for her to sit on your pretty face as my fingers force orgasm after orgasm out of you.”
Xavier exhales an expletive and nods furiously, not really caring what he’s agreeing to. Sylus knows his words have hit the spot as his lover starts to tighten once more around his cock. You call out both their names as you speed up your fingers to sync up with Sylus’ thrusts, feeling just as aroused by his words as Xavier is.
”Come for us, Xavi, you know you want to, let me see your face when you come,” you coax, and Sylus finally wraps his large hand around Xavier’s cock.
”I will fill you up like you filled her. You’ll be dripping cum well into next day, long enough for the others to notice. Do you want them to notice, love? Would you like the attention?”
The sinful words from both his lovers make Xavier’s head spin and he trashes in Sylus’ hold, his body protesting the overstimulation as his climax inevitably grows closer. He can’t breathe properly, he can’t think straight, and yet he wants more, wants everything his lovers ever offer to him.
”Yes, Sylus, princess, please —I’ll do anything, please…”
His words make no sense to anyone but him, but Sylus rewards him nonetheless by pumping Xavier’s cock tightly and biting into the junction of his neck. The world grows dark and then white-hot as Xavier cums for the last time, screaming hoarsely as Sylus and you follow close behind. Sylus thrusts into Xavier twice more before stilling, and despite being impossibly deep inside there isn’t nearly enough room for all the cum Sylus spills into Xavier. The thick white liquid gushes out from around Sylus’ barely softened cock and slides down Xavier’s thighs, making him almost as wet as you are.
”Beautiful,” Sylus whispers against Xavier’s soft hair and gently slides out of him while pressing kisses onto his lover’s temple. Xavier grabs one of Sylus’ horns for leverage as he kisses the other man back before collapsing next to you on the bed. As you wait for Sylus to bring you towels and a water bottle, you stroke Xavier’s face and watch as his tired body finally settles down.
After Sylus returns you gingerly clean your exhausted lover as well as you can, although the sheets prove to be a lost cause. You toss the towels onto the floor and lay behind Xavier’s back while Sylus faces him, curling his tail around both his lovers.
”Everything alright, Xavier?” you ask and as Xavier nods, you reward him with kisses on his shoulder blades.
”Blissful,” he murmurs and smiles weakly before drifting off to sleep. You know that tomorrow Xavier will be his aloof self again, acting like he was never fucked within the inch of his life, but the way he grasps Sylus’ hand in his sleep reassures you that if anything has changed between you three, it has been for the better.
