Falen was fortunate in the alpha his parents had chosen for him after he came of age and his true nature as an omega was revealed. Charles and Falen had known each other since they were boys-- they'd often played together growing up and they'd always gotten along so Falen had been relieved when their parents had agreed to a union between them. The omega had felt the eyes of every alpha in the village on him since he'd come of age and while the attention had been thrilling in its own way there was comfort in the familiar. He knew Charles like the back of his hand-- knew he was kind and would treat him well for the rest of their days.

Something that was far from a guarantee in an omega's life.

Betas rarely had arranged marriages-- they could bind themselves to the lover of their choice but omegas always needed an alpha. More importantly, an alpha needed an omega if they ever wanted to have an alpha child to carry on their line; a beta or a even a fellow alpha wouldn't do. As a result, the demand for omegas often outstripped the actual supply, particularly in small villages like Falen's, so arranged marriages became common practice for omegas just to keep things civil.

Falen saved himself for their wedding night after their union in the village square. Mead-drunk and heads spinning pleasantly they'd tumbled into bed together and had a pleasant time of it. Charles' hands had been rough but warm over Falen's skin and the alpha had been pleased by how much slick he'd produced and how easy it was for him to slide inside. Inexperienced in bedding omegas, it had taken Charles a few tries to find the right angle to slide into the tight, hot channel of Falen's vagina but he got there eventually and did his duty by planting his seed there. Falen wasn't in heat so the likelihood a pregnancy would take was slim but it hardly mattered.

Beyond wishing it had lasted a little longer, the omega was quite pleased.

Life settled into comfortable routine for several months with no sign of Falen falling with child before his first heat since their union came over the omega. It was his first time passing his cycle with a partner and he had been eager to experience the pleasure of being bred by his alpha while at his most fertile. He'd heard his fellow omegas speak of that uniquely euphoric sensation in the privacy of their exclusive company and even those with little love for their alphas spoke fondly of this time.

Needless to say Falen had brimmed with anticipation when he felt that familiar, maddening heat overcome him once more.

Anticipation, unfortunately, had soured into frustration and disappointment when Charles proved unable to keep up with Falen's libido.

He tried, of course, and the omega was mostly satisfied the first day, but his cycle was uncommonly long at three days and he had all but milked his alpha dry by the afternoon of the second. Charles had used a hunt the alphas had arranged as an excuse to escape his wanton mate, leaving Falen to satisfy himself with his own hands. An omega's cock produced very little seed when he was in heat-- all his body's reserves went to his womb, but he was still able to find some release through masturbation, especially when he added the fingers of his other hand to his slick-soaked hole.

It wasn't what he wanted but it was better than nothing and got him through until his mate returned later that evening and finally gave him some small dose of satisfaction.

He nearly shamed himself on the third day, however, when another of the village's alphas, Arin, came to the door in search of Charles. Calling at a house where an omega was going through their heat was the height of bad manners, and something no one in the village had a habit of doing, but Falen was too out of his mind with arousal to give it much thought. Later he would realize Charles hadn't told the other alphas the state he was in, no doubt embarrassed by his inability to keep his omega satisfied for the full length of his heat-- but in that moment all Falen could focus on was how bad he wanted an alpha's cock inside his aching pussy. He wanted-- needed an alpha's seed in him; to see his belly swell with child and feel a new life stir within him. He was an omega, producing a strong alpha child to carry on his mate's bloodline was his very reason for being-- or so his hormone addled brain insisted.

The omega watched Arin's eyes dilate when his pheromones hit the alpha and was inordinately pleased to see how the front of the alpha's pants strained against his instant erection. Falen invited him in without a second thought then immediately dropped to his knees and unlaced the front of the alpha's breeches. The omega felt a gush of slick escape him when Arin's thick cock sprang free and he leaned in to suck hungrily at his length like a starving man at a long awaited meal.

Arin tasted good-- he felt good on the omega's tongue, but the alpha felt best of all when he grabbed Falen by his hair and began to roughly fuck his mouth. Falen fought to breathe under the onslaught but he didn't pull away or struggle, simply moaned pathetically around the alpha's shaft even when Arin dragged him in so close was forced to deep throat his throbbing member. The omega took it all, eyes rolling back in his head as he reached between his thighs and worked his own dick until he came on the living room floor while the other male continued to fuck his mouth with the unrelenting tempo of a piston.

That was how Charles found them-- Falen sucking greedily at Arin's dick without a care in the world while his erstwhile partner grunted and groaned, pants around his ankles and dick halfway down the throat of his best friend's mate.

A lot of yelling and furious alpha posturing ensued before Charles threw his friend out of their house then rounded on his mate. He was angry, Falen could tell, but in his heat induced haze he only found this arousing and rather than apologize he spread his legs in submission to his alpha and offered himself.

Charles took him right there on the floor, swearing and infuriated, and it was the best Falen ever had. Charles pinned his hands to the floor with his own and fucked him hard, reclaiming what another alpha had dared try and take under his nose and the omega relished it. This was what he had wanted-- this was mating. This was an alpha breeding a fertile omega the way the gods had intended and Falen gloried in it. Charles came in him soon after and a joyous cry escaped the omega at the sense of warmth that accompanied the burst of fresh seed inside of him.

When he woke the next morning in his right mind again at last, Falen apologized to his mate, mortified by his own actions. Charles was stiff at first, but soon relented and forgave him-- the fault had been his own for not warning the village about the state Falen was in, after all. Any omega would have done the same in Falen's place.

It didn't do much to ease Falen's guilt at first but it was enough to let him move on after a few days as they settled back into normalcy.

~~~

No child came of Falen's first heat despite Charles' efforts but that was only disappointing, not surprising. A heat didn't guarantee a pregnancy, after all, only made it more likely.

Time passed and rumors of lycan sightings in the area spread throughout the village. Falen had never seen one in person himself but his mother had told him stories of the time she had many years before.

Lycans stood on two legs but were otherwise like a wolf in all ways. Covered head to toe in fur they stood head and even shoulders over the average human male and possessed incredible strength. They were a rare sight in this day and age, though. Falen wasn't sure why, exactly, beyond vague stories of how they'd fought a war in the north and wound up hunted to near extinction decades ago.

Falen's cycle returned not long after the rumors began to circulate but this time Charles warned the community appropriately and stayed home. He tried to keep up with his omega's intense libido but it was a struggle so Falen fought to reign himself in as best he could.

This did lead to a restless night for the omega, though, and Falen found himself unable to fall asleep again after he woke unexpectedly. Sleep continued to elude him even after bringing himself to completion while Charles slumbered heavily beside him, oblivious to his mate's troubles.

The omega wanted to wake him, wanted to ride Charles until he came in him again but even through the heady waves of his hormone-induced arousal he knew that wasn't a good idea. The alpha hated being woken up in the middle of the night so Falen decided to go on a walk instead, hoping the cool night air would restore his sanity.

Living on the edge of the village made it easy to slip into the forest without anyone noticing even at midday, let alone midnight, and it took only a minute at a brisk pace to lose sight of the village entirely. Falen had grown up roaming those woods and finding his way to the pretty meadow he favored for herb gathering was easy by the light of the moon.

The evening air did little to quell the heat inside him while he walked but what he found in the meadow managed to dampen it as a thrill of terror overtook the omega.

A lycan watched him from between the trees and Falen froze in place when he saw it. They stared one another down for a long moment until the breeze shifted and the wolf-man lifted his head and sniffed, as if to catch his scent.

Falen had grown up hearing tales of lycan savagery-- how they could tear a grown man in two and outrun a horse at full gallop... he'd never really believed them until now. The creature was over seven feet tall and tremendously muscular, covered head to toe in a silvery pelt that caught the light of the moon like fresh-fallen snow. It was both terrible and beautiful to behold and Falen knew instinctively he stood absolutely no chance of escaping if it decided to attack.

Slick trickled down the inside of the omega's thigh and Falen realized that while he was terrified out of his mind he was aroused as well. Base instincts warred inside the omega-- survival and mating, but survival finally won out and Falen started to back slowly away. Even as he did, however, he was chased by the thought of alternative options.

He could lay down, offer himself to the lycan-- his body in exchange for his life. He could let it hold him down with its massive hands and rape him until it was satisfied. A fresh gush of slick dripped from Falen's throbbing hole as he considered how such a large male would no doubt have an even larger cock. Big enough to break him. Big enough to fuck him senseless until he'd be useless for anything but serving as the beast's willing cock-sleeve...

Falen hastily pushed the thought aside as insane then screamed when the lycan suddenly surged forward in his direction. The creature covered the distance in a blink-- so fast the omega didn't make it more than a few steps before it was on him. He tried to scream again when the lycan pushed him to the ground but the creature covered his mouth with one of it's massive, clawed hands and loomed ominously over him.

Whatever questions Falen might have had as to the creature's member faded immediately as its massive cock slipped free of its sheath, already half-hard and growing harder by the moment when it leaned in and pressed its cool, wet nose to Falen's neck and inhaled deeply of his scent. The omega scrabbled at the lycan's wrist, trying to wrench it free of his mouth, but to no avail; he might as well have been fighting an oak tree.

The lycan licked the same spot it had sniffed and a shudder that was an even mix of fear and arousal shook the omega when he felt it's sharp teeth graze over his skin. An omega could always sense an alpha, especially while in heat, and everything about the lycan screamed 'alpha'-- it took everything in him to resist the urge to spread his legs for the beast right then and there.

As if he could sense the impulse, the wolf crouched lower over Falen and the omega felt the shocking weight and heat of the lycan's massive cock land on the surface of his belly with a fleshy slap then begin to slide rhythmically up and down it. A low, pleased growl escaped the wolf as he enjoyed the brush of the omega's soft skin against his hot, swollen member.

Perhaps, Falen thought, it would satisfy itself by rutting against him then leave him be. Or perhaps, that darker part of him that had imagined just this situation on first seeing the lycan whispered, it won't. He tried to ignore the treacherous and increasingly difficult to ignore voice but was soon distracted when the lycan tore what scant clothes the omega had left the house with clean off of him then cast them heedlessly aside.

Survival instincts managing to trump the other once more, Falen renewed his attempts to writhe free of the lycan's grasp, but his struggles were laughable as a child's before the wolf and it was nothing at all for the alpha to use his free hand to prize the omega's thighs apart then settle between them so he couldn't close them again. The lycan's cock slid along the length of Falen's when he did and the omega's eyes fluttered at the sensation but flew wide again when it passed and he felt the tip press against his entrance.

Falen wanted to resist the lycan, or so he tried to tell himself, but his own body betrayed him as his slick, greedy hole spread readily to accept the strange alpha's cock-- as if welcoming home its true master at long last.

It was long-- it was so fucking long and thick Falen screamed into the lycan's palm in pure, unadulterated ecstasy coupled with the sweet, sharp pain of the wolf's shaft stretching him wider than he ever had been before when it thrust into him. The shape of the alpha's cock curved perfectly to plunge straight into his pussy on the first try and even pushed out the surface of the omega's belly to accommodate its length.

The lycan thrust a second time and Falen writhed beneath him, eyes rolling back in his head while his head spun at the shocking onslaught that commenced. The beast proceeded to fuck him hard and rough, taking what it wanted with little concern for how willing it might have been given.

It was raping him but Falen had never felt so fulfilled in his life.

Barely more than a minute in all thought of resistance left the omega-- not because he had given up hope but because he wanted it. Wanted the wolf inside him, over him, dominating him the way he'd always wanted to be but Charles had never really managed. Falen had never felt so helpless or so aroused and the wolf seemed to realize it as he soon withdrew his hand from Falen's mouth and used it to brace himself instead.

Falen wasn't going anywhere and they both knew it.

If he screamed again it would only be with pleasure.

The omega spread his legs wide for his new mate and moaned when it began to fuck him harder yet-- so hard the surface of Falen's belly undulated obscenely with every thrust of the wolf's massive member.

It really was the perfect shape-- like it had been crafted to fit Falen's body to perfection despite stretching him well beyond all his previous limits. That incredible length and perfect curve allowed the tapered head of the lycan's dick to plunge through his hole and directly up into his pussy to strike the mouth of the omega's womb like a battering ram with every thrust of his hips. Its incredible girth stretched him impossibly wide, so much so Falen was sure he would never walk right again but he didn't care-- how could he in the face of how full it left him feeling? Falen never wanted the lycan to stop fucking him; he would gladly spend the rest of his life on his hands and knees as the alpha's cock sleeve if that was what it wanted. Anything to capture this feeling...

As if he'd read Falen's thoughts, the lycan withdrew just long enough to put the omega on his hands and knees in the grass then thrust back into the hole left gaping by his cock's absence. A crow of ecstasy escaped Falen at the sensation and he threw his hips back to meet the wolf's. This was what he'd been craving. He needed to be fucked and dominated like a bitch and apparently it'd taken a wolf to do it. In that moment the lycan was his entire world and submitting to it fulfilled some bone deep need the omega hadn't even realized he had until it was finally satisfied.

He'd found his alpha.

Not the one he'd spent his childhood with-- the one his parents had arranged for him... no, he'd found his real alpha.

"Harder! Fuck me harder, damn you," Falen pleaded heedlessly even as he felt the knot swelling at the base of the lycan's cock begin to knock against his entrance, spreading his hole ever wider. "Rape me like you mean it-- make me yours! Take me!"

The lycan grabbed Falen by the back of the neck and forced his face down into the grass with a snarl and proceeded to thrust so hard and fast into the slender sheath of his body the omega felt he might be split in two-- though he welcomed it. From this angle he could look down at his stomach and see the way it bulged out with each thrust of the alpha's cock and he smiled, sex-drunk and aroused beyond all reason as wave after wave of pleasure threatened to drown his sanity.

"Breed me," he panted desperately into the grass though he had no idea if the lycan could even understand him. "Breed me-- put your pups in me, I don't care just... fuck! I need it, I need your seed. I want to be pregnant, I need--"

With one hard, final push and a snarl of effort, the lycan's fist-sized knot breeched Falen's tight hole then popped inside, locking the omega firmly in place against the wolf. Falen screamed and came, seed spilling itself across the grass beneath him, sobbing and overstimulated as his new mate continued to thrust down into him. The wolf's knot yanked back against the inside of Falen's ass with every jerk of his hips, dragging another yell from the omega while he drooled and gasped at the strength of his orgasm around the alpha's dick. He'd thought he'd felt full before but that was nothing compared to now as the pressure the wolf's knot exerted on his prostate stretched the omega's orgasm impossibly long. Weeping openly, he'd swear he'd completely drained his balls and yet still the pleasure continued to echo through him so his walls clenched tight as a vice around his new mate's cock.

The sensation must have been enough to finally tip the lycan over the edge as he came with a howl a moment later and Falen felt a flood of heat gush forth into his belly as the wolf's seed filled him to the brim. There was so much of it-- an impossible amount of come from a human and pure bliss for an omega mid-heat begging to be bred.

A sob of pure gratitude escaped Falen and he rocked his hips to milk every last drop from the alpha, weak from exhaustion but determined to claim what he wanted from the wolf.

They were locked together like that for some time and the flow of come didn't slow but continued to pump into Falen until his belly swelled noticeably.

"Gods help me," Falen whimpered blissfully, ass in the air with the lycan's cock still locked firmly inside of him, knot acting as a stopper to keep the impossible amount of molten seed inside of him. Falen's back arched under the weight of his stomach and he moaned when he reached back to stroke one weak, trembling hand over its taut surface. It triggered something deep inside him-- satisfied, if only temporarily, his desperate desire to be pregnant even if that wasn't actually possible with a lycan. Their genetic incompatibility didn't matter in that moment, though-- Falen simply allowed himself to relish the feeling of the wolf's seed pooling deep within his belly, cock twitching while the omega's aching pussy throbbed pleasurably around his impossible length.

Eventually, the lycan's knot shrank enough to let the wolf pull free of the omega's body and stand once more. Falen cried out and sagged to the ground in a gush of hot come that poured from of his freshly loosened hole and fought for breath, weak and trembling as a newborn lamb after his experience.

For the first time since his heat began, the omega felt satisfied and watched through hazy eyes as the lycan regarded him with what Falen could only describe as a look of satisfaction, then walked away.

~~~

Reality eventually caught up to Falen as the sky began to lighten between the branches of the trees that stretched overhead. Unsure how long he'd laid there on the grass after the lycan left the omega sat up and felt a fresh gush of wolf seed pour out of him at the sudden shift. He groaned at the feeling, unspeakably aroused even through the shame as he remembered his mate in bed at home. Charles would be waking soon but here Falen was, so full of another male's seed his stomach was visibly swollen...

Falen's own cock twitched with arousal at the thought but he ignored it and instead braced himself then pushed in an effort to expel the rest of the lycan's come from his body. He groaned with the effort, head thrown back and mouth hanging open while the still-hot liquid poured out of him. When no more would come, he looked down and found his abdomen back to normal and a veritable pool of seed quickly soaking into the grass beneath him.

What would it be like to be permanently mated to such a creature? To be so filled every day?

A little shudder of pure, unadulterated longing shook the omega but he buried the thought just as quickly and forced himself to his feet. His clothes were in tatters but he collected them anyways and hurried to the nearby creek to remove all signs of his indiscretion before hurrying home in the wee hours of the morning, shadows just deep enough to mask his passing.

Falen managed to slip into bed without Charles any the wiser. An hour or two later his mate woke and immediately rolled over to press his growing erection into the omega's back.

"Morning," the alpha said, voice rough from sleep even as he angled his hips and thrust up into Falen without waiting for an invitation he knew wasn't needed.

"Morning," Falen replied, feigning sleepiness despite having done little more than doze since his return home. The lycan had managed to leave him fully satisfied for a time but Falen could already feel his heat starting to return so the moan that escaped him when Charles slipped inside him was in earnest.

Unfortunately, after what he'd experienced the night before, Falen was less than satisfied when his mate finished a few minutes later. With some trepidation as Charles got up and went to the bathroom to clean up, the omega realized his tryst the night before had completely ruined him for human cock. Charles was a well endowed man but after what the wolf had done to him, the way he'd knotted and then filled him like a proper submissive breeding bitch...

"I have to go into the village for a bit, will you be alright?" Charles asked as he returned and got dressed.

"Of course," Falen nodded and smiled as he moved to do the same. "I'll try and get some cleaning done while you're gone."

Charles seemed surprised, and then almost relieved. "Cleaning? Maybe your heat is getting shorter," he mused and Falen realized his mistake.

"Well, I said try," he teased and Charles sighed then chuckled and kissed him briefly.

The relief from his heat the lycan had given him was officially gone a couple of hours later which left Falen struggling to focus on hanging up laundry on the line behind the house. Frustrated, the omega dropped one of the clean bed sheets then gave up and threw himself down on top of its cool, wet surface and proceeded to jerk himself off in hope of some relief.

Unsatisfied with just his dick, however, the omega stripped off his pants and thrust as many fingers as he could into his already slick hole and tried to satisfy himself that way. Before he could come, a shadow passed over him and Falen opened his eyes to find the lycan looming over him.

"You," he gasped, so shocked for a moment he thought he was dreaming. Heart pounding, he sprang unsteadily to his feet and stumbled back towards the house. He fetched up against the back door but found himself unable to open it when the lycan reached over him and held it shut with one massive hand.

Falen could feel the heat of the alpha against his back and he shivered as he remembered the night before. His dick twitched and his hole practically throbbed, longing to be used, to be ravaged by the lycan's huge cock again.

A low growl rumbled up through the alpha's chest and Falen cast a glance back over his shoulder, then up into the wolf's face. He didn't appear threatening, only... focused.

Focused on him.

Heart pounding and breathing shallow, Falen didn't say anything else, but arched his back to present his ass to the wolf, hole wet and ready for him, the way an omega was meant to for his alpha.

He shouldn't, he knew he shouldn't, especially not when Charles could come home any moment, but Falen could no more deny his body what it craved than a stream could flow uphill.

And it craved wolf-seed.

The lycan lifted his hand from the door then used it to stroke the length of Falen's back, sending another shiver down the omega's spine. Stomach hot and tight with need, Falen braced his own hands against the door then shifted back until he felt the tantalizing brush of the lycan's rapidly growing erection. The creature growled again, low and pleased this time and the omega repeated the motion, rocking his hips so the wolf's cock slid up and down the cleft of his ass before he hooked down with a deft twist of his hips and forced its head inside of him. He dropped lower, slowly impaling himself on the alpha's thick member one glorious, hole-stretching inch at a time while a cascade of euphoria overtook him.

"Oh gods yes, this is what I wanted," he moaned aloud as he jerked his hips up then back down again until he was fucking himself on the wolf's cock. "Charles fucked me this morning and all I could think of was you," he confessed breathlessly, eyes sliding shut. "You've ruined me, turned me into a wolf-fucking whore..."

If the lycan could understand Falen's words he didn't seem to care or feel the slightest bit of shame that he'd turned another alpha's mate into a slut with a craving for wolf-cock. Falen couldn't tell if he was pleased, either, but the wolf did take him by the hips and thrust into him with a sharp jerk that saw him sheathed to the hilt in the omega's hot, needy cunt. It took everything in Falen not to scream, but he just barely managed to stifle his cries as the wolf started to fuck him in earnest against his own back door.

Again there was that perfect feeling of fullness as he rode the lycan, particularly when the alpha picked him up like he was nothing and turned Falen around so the omega's back was against the door, legs wrapped tight around the wolf's hips. The angle allowed the alpha's dick to penetrate him so deeply it drove the breath from Falen's lungs and all he could do was throw his arms around his mate's neck and ride it out.

"Fill me," he pleaded desperate and breathless, fingers knotted in the wolf's thick pelt as he was bounced relentlessly up and down the full length of his massive shaft. No human could fuck like this, not for this long, and Falen was once again beginning to lose his coherence under the onslaught. "Fill my womb with your seed, Wolf! You want me as your bitch then make me your bitch!" Falen demanded and threw himself down hard on the wolf's dick until he forced the knot at the base up inside of him once more. He barely suppressed another scream, this one of delight at the fullness and the shock of the sudden knotting must have set off the lycan as he came a second later with a snarl.

He thrust brutally against Falen, throwing him back against the door so hard the omega was sure he'd bruise later but he didn't care. The lycan jerked his hips back hard enough to yank his knot free, dragging a yelp from the omega, only the thrust it immediately back in again so the omega arched his back and went rigid in his arms, a silent howl contorting his features as he struggled to remain silent.

Repeated penetration by the wolf's increasingly massive knot brutalizing his slick hole pounded an orgasm right out of the omega. Falen's seed burst forth to paint the lycan's belly even as the lycan himself began to coat his insides with come and the omega bit his lip so hard it nearly bled in an attempt to muffle a scream as the wolf's knot penetrated him one last time before finally proving too large to yank free once more. Falen groaned and shook, held in place by the hard press of his mate's body as that sweet, hot tied of wolf-seed filled him to the brim then forced his belly to swell outward.

Surely, he thought, breathless and sweating as he leaned back in an attempt to make room in his abdomen, it was at least half a gallon of seed? How any one creature could produce so much come was beyond him but Falen was grateful to every god he could name he had made the discovery.

The lycan bowed its head and the omega instinctively lifted his chin for his alpha and parted his lips so he could slide his broad, flat tongue into his mouth for a lingering kiss. It took a moment to find the rhythm of kissing such a peculiar mouth with so many very sharp teeth, but before long Falen had thrown his arms around the lycan's neck and tilted his head to allow him to plunge his tongue into the deepest recesses of his mouth.

Oh if Charles could only see him now...

The thought sent him tight around his alpha's gradually softening cock and just that little bit was enough to send the creature hard again. Falen gasped in surprise when, rather than pull out, the lycan began to thrust again, though not so much as to pull his knot free, and the motion was enough to make the omega's swollen stomach visibly bounce.

"W-wait," he gasped breathlessly though he made no effort to actually pull away, only moaned as he felt his mate's knot begin to swell inside his ass again. "I'll burst," he groaned low in his chest, the subtle sloshing of all the seed already in his belly strangely erotic to him now.

Just how much could he take?

It didn't take long to find out. The lycan stepped back from the door, arms wrapped tight around Falen and fully supporting the omega's weight as he fucked up into his overstimulated body. The thrust of the wolf's hips were shallow but hard, the slap of their hips together so strong the omega bounced under the onslaught, overfull stomach jostling in time.

The lycan came again a moment later without having ever pulled his knot free and their bodies remained locked together as he emptied another load into the omega, forcing his belly to swell further.

The pressure building up inside Falen was intense and made him lose all coherence and go rigid in his alpha's arms, back arched back in a vain attempt to make room for his seed. When the tide finally died down, Falen struggled to catch his breath and looked down at his now massive stomach in awe and a flash of terror. He felt like if he moved too quickly he might burst, but at the same time he'd never felt so complete in his life. This was how he was meant to be, round and with his mate's seed, heavy with his child, locked in an eternal cycle of mating, pregnancy, and birth.

"Thank you," he breathed and leaned up to kiss his alpha again.

The lycan growled low and returned the kiss then carefully laid them both down on the sheet so they could remain locked together awhile longer. It took some situating, but eventually Falen lay with his back to the lycan's chest, the massive alpha curled around him and stroking the taut surface of the omega's belly with one clawed hand.

It was pure bliss, laying there under the sun, and all it took was a little, gentle bouncing of his alpha's hips to set Falen's belly rocking before he too reached a second orgasm. A wanton moan escaped him as he jerked himself off, alpha's cock still firmly lodged in his ass, and spilled his own seed across the once clean surface of the sheet on which they lay.

Finally sated, Falen dozed awhile until the lycan withdrew his cock with a gush of hot come that startled the omega back into waking. "W-wait!" Falen gasped but it was too late. The sudden shift in pressure broke the dam and his alpha's seed poured out of him in a solid, uninterrupted stream that left Falen writhing and moaning, soaked in their mess from the waist down. He still had a slight bump when it stopped and he sat up then forced the last of it out while the lycan strode away into the forest once more.

Disappointed but undeniably sated, Falen cleaned up as quickly as he could though he only barely made it in time to welcome Charles home with an enthusiastic blow job lest the man notice how loose the omega's hole was in the wake of his illicit coupling.

~~~

Falen's heat finally ended the next day and the lycan did not return. The omega was relieved and disappointed in turns, though he always felt guilty when he strayed into the latter. Charles was a good man, he reminded himself every day when he woke up from another night of erotic dreams that left his pussy dripping and craving his true alpha.

Fortunately, Charles remained none the wiser to his mate's indiscretions and it got easier for Falen to bury the memories as the weeks passed-- especially when the omega's belly began to swell of its own accord and he realized he was finally with child.

The fact that anyone but Charles might be the father didn't even cross Falen's mind. The alpha was pleased by the development, and Falen himself was over the moon to finally be pregnant, so that was all that really mattered.

Or so he thought, anyways.

At first it was all wedded-bliss as Charles heaped affection on Falen and the child blossoming within him, but it wasn't long before the omega grew restless. Now that he'd been successfully impregnated he no longer went through his heat-cycle but that didn't mean he didn't want to be fucked. His libido was not only intact, but the most voracious it'd ever been outside the omega's breeding heat.

Charles, though, was hesitant to do more than the most gentle of lovemaking out of an abundance of caution for their child, and even that he had be be cajoled into by his libidinous mate. Falen needed it rough. Needed to be taken by his alpha, child in his belly or no, and Charles proved far from satisfactory in his attention, though the omega did his very best to hide that fact from him.

He'd gotten what he wanted, hadn't he? The seed Charles had planted in his womb was growing fine and strong within him at last, yet Falen couldn't help but feel there was something wrong with him as his mating urge only seemed to intensify as the days and weeks passed. It wasn't he blazing inferno of need he experienced while in heat, but it was a steady and well-tended fire that never guttered or faded where it burned within him.

The only cure he found was the wolf.

Twice a month it visited. Every new and full moon he would see it watching him from the forest's edge around midnight and every time he would creep from his bed, Charles none-the-wiser, to meet it. Only then was the fire quenched by the torrent of the lycan's seed pooling within him, the throbbing ache of his cock-starved cunt eased by the iron-hard girth of his true alpha's superbly knotted dick...

The wolf was never gentle with Falen. It took him in its powerful, clawed hands and ravaged the omega's beautiful, nubile body to sate its own rapacious lust with only the slightest of care given for it's bitch's occupied womb. While it fucked him hard and rough as a bull in rut throughout the night, it made sure never to press too hard on Falen's growing belly during their savage love-making.

Together they took to sneaking away deep into the woods for their liaisons as Falen grew loud as a cat in heat during their coupling, howling like a beast himself when the lycan knotted him and pumped its thick, hot seed into him. As the months went on he grew capable of carrying on the whole night like that with the wolf, more beast than man himself as he writhed and moaned beneath the snarling, panting beast-- or sometimes even astride it, when the mood took him.

His body changed by leaps and bounds as his pregnancy grew nearer and nearer to term. Falen was not a tall man so his belly jutted proudly out from his torso quite early and only expanded from there-- there was certainly no hiding the state he was in; not that he wanted to. The omega took great pleasure in the appearance of his transformed body, particularly once his milk began to come in and his breasts grew to accompany his growing waistline. His fascination grew to such a point that when Charles left the house for the day he'd often spend some time standing before the mirror admiring his pregnant body, which lead to an hour or more of masturbating to the view of himself.

Charles, while pleased to have successfully impregnated his omega, was not particularly aroused by his mate's pregnant state. The lycan, on the other hand, seemed completely infatuated with Falen's changing body. It loved to fondle, grab, and stroke the continuously expanding surface of Falen's stomach, particularly while they fucked-- but after as well, when their bodies were still knotted together. Where Charles was somewhat put off by the mess when Falen began to lactate, the wolf was enthusiastic-- groping, milking, and suckling from the omega's teats until they were all but drained from the attention.

"Fuck," Falen moaned one night eight months into his pregnancy when the wolf mounted him and pushed deep inside of his already crowded body. Even taking his height into account the omega's pregnant belly had swollen to an extraordinary size this late in his pregnancy-- so much so it pressed into the soft, cool grass when he was on his hands and knees before his true alpha, moaning like a slut, Charles completely forgotten for the time being. Falen always felt guilty the morning after when he sneaked back into bed, shame-faced yet sated, but that was a few hours off yet and his coupling with the lycan had only just begun.

"Fuck me," he pleaded wantonly as the wolf's thick cock plunged in and out of his hole with such vigor the omega's tits and belly both bounced in time to its thrusts. "Fuck me like I'm your bitch! You want your pups in me, don't you?" he moaned, groping his own tits with one hand until they gushed milk, aroused by the idea of carrying a litter of the lycan's pups in his belly instead of Charles' baby. "Yeah you do," he panted, tongue hanging out, eyes rolling back with pleasure as the alpha picked up his pace and pounded into him, knot beginning to blossom at the root of his cock. "Want to rape your pups into me... put them in me! Use me, make me your bitch," Falen groaned, throwing his hips back to meet the lycan's thrust, forcing its knot into his cunt in the process so they both came, twitching and groaning with pleasure in the process.

When the lycan finished coming, they started again.

Nine months in and due any day now, Falen's belly had swollen to a truly impressive size-- so much so he'd forgone trying to fit into normal shirts and transitioned to simple wrap tops that at least supported his milk-heavy breasts.

Even in that state, Falen still had work to do around the house, and that meant gathering herbs in the forest, for which Charles insisted on accompanying him. It was a sweet offer the omega appreciated-- all the more so when he unexpectedly went into labor soon after reaching the deepest parts of the forest.

A gush of fluid burst from him and he knew his water had broken and while Charles tried to insist they return to the house so he could fetch the midwife, Falen knew it was too late.

The baby was coming now.

The omega barely had time to strip out of his breeches before another contraction dropped Falen, screaming, to his hands and knees while his alpha fluttered uselessly around him. The pain of his contractions were intense but there was a part of Falen that was undeniably aroused by the process as he felt his child force its way through his cervix and into his vaginal canal.

"It's coming!" he screamed and, to his embarrassment, orgasmed the moment the baby began to breech his cervix. He moaned, low and guttural like the whore he was, hips jerking so his cock slapped against the distended surface of his pregnant underbelly, spilling its seed in the process. Fortunately, Charles took it for another cry of pain, rather than arousal at the prospect of giving birth.

"Deep breaths," Charles said as he guided his laboring mate to lay on his back beneath the nearest tree while the sun sank towards the horizon. "Push!"

"I am!" Falen groaned. He'd been feeling full and heavy for months, but that sensation shifted much lower in his abdomen now, leaving him breathless and panting as he fought to push the baby from his body.

Minutes dragged on as one contraction after another hit Falen in rapid succession until the omega was howling under the onslaught, torn between agony and ecstasy as their child was forced through his cervix and down into his birth canal. "FUCK it's big!" he screamed, eyes rolling back in his head as he gasped for breath and clutched helplessly at the grass beneath him for purchase.

"It's crowning!" Charles cried and Falen felt his mate's hands on his flushed skin, slick with sweat from the efforts of labor. "It's--" Charles hesitated but Falen barely registered it as he grunted and groaned his way through a mighty push that finally delivered his firstborn into the alpha's hands.

Trembling and breathless, Falen felt more contractions coming and said, "Oh gods, I think there's another!" Only then did he realize he hadn't heard anything from his mate, who sat on his heels with their squirming, squalling, birth-damp firstborn in his hands.

"You--"

"Ah! What? Is something wrong?" Falen panted as his labor pains started afresh. Apparently, he realized with some elation, he was having twins. No wonder he'd been so big!

"You fucking whore."

Startled, Falen focused on his mate, and more importantly, the child in his hands. Looking at it properly now, he could tell it wasn't human.

It was lycan.

Furless at birth, it still had a wolf's face, ears and tail, and as he looked into Charles' face, Falen knew there was no point in denying what he'd done. "I-I--" Before he could get any words out, though, another powerful contraction wracked his body and his words turned into a scream.

His second... pup slid into position, ready to be delivered and when it breeched it came pointed ears first. That was enough to make Charles put the first pups down at Falen's side, as if he couldn't stand to touch it, a look of disgust contorting the familiar lines of his face.

"You fucked one of those beasts? Let it take you? Put its foul seed in you?"

The second pup was either larger than the first or Falen's distraction was making it harder to push in time with his contractions. "I'm sorry! Charles, I'm so sorry!" he moaned. "I couldn't-- gods, my heat was just too much and... and when it attacked me I-I let it! I'm sorry!"

"Tell me it was just the one time," Charles said, though there was a flash of steel to his eyes that made it obvious he wouldn't be easy to convince.

Laying there in the grass, laboring to birth a lycan's pups, Falen was incapable of meeting his mate's eyes.

"Fuck!" Charles swore and lunged to his feet. "You beast humping little slut of a he-bitch! I can't believe I married a worthless whore! All these years I waited and you go and get knocked up with a beast-man's litter! Should have known I couldn't trust a bitch whose heat lasts three goddamn days! Born sluts like you can never stay loyal... Gods only know who or what else you've spread your fucking legs for!"

"N-no!" Falen panted and shook his head rapidly. "J-just the one! Just the lycan I swear!"

"Oh fuck off you fucking slut! One is enough!" he snarled and, with that, turned on heel and left.

Another agonizing contraction and Falen pushed with a scream as he continued to labor there in the forest on his own. Finally, after some minutes, he managed to push the second pup free of his body in a gush of fluid soon followed by the placenta and the omega sagged back into the grass sobbing with relief.

Just as he began to wonder what he was going to do, his alpha, his true alpha appeared. They didn't share a language, but Falen could tell it was pleased by its pups as it knelt at his side and began to clean them up, easing the omega's fears of abandonment.

What did he need a man like Charles for anyways when he had a wolf for an alpha, he thought as it leaned in and kissed him while their pups began to suckle.

When they finished, the lycan gathered his mate and his pups up and carried them away into the safety of the forest depths.
