Genes of powerful hybrids ran in Xavierâs family, so it hadnât 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 firstbornâs 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 hadnât 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 fatherâs 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 wouldnât accept him, he would find people who did.
To say his wish had been granted would have been an understatement.
âXa- Xavier, ahhââ
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 canât help nipping at your warm skin as he pushes the both of you closer to the edge.
âThatâs it, Starlight,â he says and winds his arm around your waist, pulling you impossibly close, âsay my name, louder â. 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.
âGoing to fill you up again Starlight, can you feel it?â. You instinctively tighten around him, every muscle tensing in anticipation.
âThatâs my girl, taking me so well. You are so full of my cum already, arenât you?â Xavier caresses your stomach with tenderness that doesnât 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.
âF-fuck, Xavier, so close, donât stop, please .â 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 couldnât 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 werenât much phased by their intense and often physically intimidating mating habits.
But the drawbacks of Xavierâs 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 isnât 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 doesnât 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.
âTwinkle twinkle,â 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.
âSorry princess,â he murmurs. You curl up on your side and lay your own hand upon his.
âItâs okay Xavi. Would if I could,â you smile tiredly at him. âIt makes me sad too to see you like this and not be able to help you.â
Despite the lack of stimulation Xavierâs 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 itâs a futile effort. Once he is deep into his rut he canât 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.
âSounded like you two are finished,â 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 isnât deterred and instead lets his gaze roam over both your naked forms, unabashedly enjoying the erotic mess you have made of one another.
âHow are you doing?â Sylus asks as you hand the glass back to him.
âBlissful, as always,â you sigh and flop back onto the mattress, âbut I donât think I can continue further. Even ifâŚâ you trail off and turn to look at Xavier again. Xavierâs eyes are fixed upon you in favor of ignoring Sylus, who is looking amused by the bunny-hybrid's predicament.
âRut still hasnât gotten easier for our bunny? You should be lucky yours only last for a couple of days, unlike our mermaidâs heat cycle.â
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 doesnât mean he isnât struggling with the scent of desire that now permeates half of their shared home, courtesy of Xavierâs rut.
Sylus bends down at the waist to meet Xavierâs gaze head on. He takes the empty glass from the blonde and then places his index finger under Xavierâs chin, lifting up ever so slightly.
âDo you need my help, bunny?â
Xavierâs 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 hadnât 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 wasnât 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. Xavierâs chest rises and falls in sync with his deep breaths, and his cock bounces against his taut stomach. Sylusâ red eyes are fixed on him, dark with lust and affection, and his tail slithers onto the bed and around Xavierâs hip.
âYou need to use your words, Xavier,â Sylus drawls as he plays with the knot of his bathrobe. Xavierâs eyes dart up and down the dragon-hybridâs body as his self-restraint fights a losing battle. Sylusâ tail slides up Xavierâs spine, and the blonde draws a shuddering breath before swallowing harshly.
âPlease,â he finally says, âI needâŚmore.â
Sylusâ grin widens and his pupils blow out until his irises turn completely black.
âPresent yourself to me,â 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. Sylusâ 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 Sylusâ next move, his impatience betrayed by his darting eyes and shallow breathing. Sylus coats two fingers in lube and grabs Xavierâs raised leg by the ankle with his free hand.
âHas it been a long time?â he asks as he circles Xavierâs hole. Xavier sucks in a breath through his teeth and nods. Sylus focuses his eyes on Xavierâs face and slowly pushes one finger inside.
âBreathe, bunny.â
Immediately Xavierâs 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.
âYou can help him relax, sweetie. Soon he will get impatient and start to demand I fuck him only half-prepped.â
Xavier opens his eyes ready to retort the dragon-hybrid's words but is cut off by Sylusâ finger curling into his prostrate. Xavier lets out an uncharacteristic âfuckâ and Sylus adds a second finger as Xavier is distracted. You scoot over to Xavierâs side and stroke his stomach, easing the tension thatâs built up there. As you feel him relaxing under your touch, you trail lower and curl your hand around Xavierâs 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 Xavierâs 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.
âAlready?â Sylus hums as Xavier tightens around his fingers, the mean undertone in his words only pushing Xavier closer to his climax. âBetter hope this isnât the last one you are giving me.â
You are lucky you have learned the telltale signs of your loversâ impeding orgasms as Xavierâs 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 Xavierâs leg to grab your head and pulls you in for a messy kiss, taking his share of Xavierâs cum. When you part his lips are glossy and tainted white.
âYou taste heavenly, little princeling.â
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.
âSafeword?â
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 Sylusâ 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.
âIâm so jealous, Xavi,â you whine playfully as you scratch your blond lover at the root of his furry ears, âwhen Sylus fucks me it feels like heâs reaching my soul with that cock.â
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 itâs still always intimidating to see him in his full glory. And despite of that Xavier crawls towards him on all fours without hesitation.
âYou sure about this bunny?â Sylus asks as Xavier lolls his tongue out and places kitten licks on the reddish tip. Sylusâ cock feels white-hot on Xavierâs tongue, courtesy of the dragonblood pumping through his veins. Xavier ignores Sylusâ question and closes his eyes, lips wrapping around the cockhead as he lets his mind turn on the autopilot.
Sylus sighs and pets Xavierâs head while you coo praises into the bunny-hybridâs ear, scratching it again in a way that you know makes Xavierâs cheeks heat up. Sylusâ tail coils behind Xavier, and the hard scaly tip rubs against Xavierâs 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 Xavierâs lips and tightens his hold on Xavierâs hair enough to make his lover focus.
âOn all fours. Place a pillow under yourself.â
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.
âI thought that was your favorite position, Xavi.â
It is, and thatâs why he knows just how deep inside you he can reach. Xavier is painfully hard, but he canât 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.
âYou know Sylus wonât hurt you, right?â
To emphasize the same point Sylus bends over Xavier, his cock resting on Xavierâs rear, and turns Xavierâs 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 Xavierâs upper chest and nuzzles his neck, much like Xavier had done to you earlier.
âRelax for me, love.â And then he starts to push in.
You swallow Xavierâs moans and hiccups with your mouth and rub his scalp as Sylus sinks in inch by inch. His replaces his arm around Xavierâs chest with his tail and spreads Xavierâs 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 Xavierâs prostrate, and the bunny-hybrid starts rocking his hips against the pillow.
âHeâs in so deep, princess,â Xavier gasps against your lips. âIâmâIâm gonnaâŚâ
âNot yet Xavi, he isnât even all the way in yet,â you tell him and wipe away a stray tear from his cheek. âYou are doing so well for Sylus, such a sweet little bunny.â
Xavier keens from the praise as Sylus finally bottoms out. Sylus growls as he lowers himself flush against Xavierâs back. He starts to rock back and forth minutely, and you release your hold on Xavier, giving him another pillow to hug as Sylusâ weight pushes his upper body down into a mean bend.
âSuch a tight little bunny,â Sylus groans as he places his other hand onto the nape of Xavierâs neck, âso hot, so perfect. Tell me, will this be enough to satisfy your rut?â
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 Sylusâ hand tightens around his neck, and the next thrust on his prostate makes stars explode in Xavierâs 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 doesnât stop completely. Instead straightens up onto his knees and pulls Xaviers hips flush against his, making his lover scramble for purchase with his forearms.
âNot enough,â Sylus rasps, âhow many times you made her come tonight? Four?â
âOnly three,â you muse as you lean back against the headboard, enjoying the show your lovers are putting on for you, âbut maybe you should aim to top that.â
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 doesnât 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 Xavierâs jaw.
Your arousal comes back with vengeance as you gaze upon Xavierâs wrecked state, his poor cock still half-hard as his eyes struggle to remain open. Sylus pushes his thumb into Xavierâs open mouth and the blond sucks on it with a pitiful whine.
âHas our bunny finally been fucked silly, hmm?â 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 âah-ahâ 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.
âHow about next time you think ahead, and ask one of us to join you from the start. Wouldnât it feel good to be taken at the same time as you take her? Or maybe youâd prefer for her to sit on your pretty face as my fingers force orgasm after orgasm out of you.â
Xavier exhales an expletive and nods furiously, not really caring what heâs 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 Sylusâ thrusts, feeling just as aroused by his words as Xavier is.
âCome for us, Xavi, you know you want to, let me see your face when you come,â you coax, and Sylus finally wraps his large hand around Xavierâs cock.
âI will fill you up like you filled her. Youâll 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?â
The sinful words from both his lovers make Xavierâs head spin and he trashes in Sylusâ hold, his body protesting the overstimulation as his climax inevitably grows closer. He canât breathe properly, he canât think straight, and yet he wants more, wants everything his lovers ever offer to him.
âYes, Sylus, princess, please âIâll do anything, pleaseâŚâ
His words make no sense to anyone but him, but Sylus rewards him nonetheless by pumping Xavierâs 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 isnât nearly enough room for all the cum Sylus spills into Xavier. The thick white liquid gushes out from around Sylusâ barely softened cock and slides down Xavierâs thighs, making him almost as wet as you are.
âBeautiful,â Sylus whispers against Xavierâs soft hair and gently slides out of him while pressing kisses onto his loverâs temple. Xavier grabs one of Sylusâ 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 Xavierâs 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 Xavierâs back while Sylus faces him, curling his tail around both his lovers.
âEverything alright, Xavier?â you ask and as Xavier nods, you reward him with kisses on his shoulder blades.
âBlissful,â 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 Sylusâ hand in his sleep reassures you that if anything has changed between you three, it has been for the better.
