For The Greater Good

SubStar Commission for Femukki

By Rix Writes

Hot, stifling air laced with the scent and taste of both sulphur and brimstone seared Mukki's lungs as she hung, naked, from a pair of steel manacles. Her legs were held open by two more manacles on short chains attached to iron rings in the floor. Her broad wings were bound and fettered with leather straps that held them closed behind her. Before her stood a tall, ebon-furred old wolf, his lanky frame draped in a tattered old robe, his leering yellow eyes taking in the sight of her. Behind him, the old cellar's stone walls were painted in with arcane sigils that glowed a sickly orange, the only source of light in the room. The floor of the cellar was covered in a summoning circle, its paint-strokes drawn in the helpless bat's own blood. She could still feel the small wounds on her arms and legs that the wolf had cut into her flesh, each of them precise and deliberate, forming arcane runes, each one of them part of the summoning that would call across worlds to bring, ever so briefly, a creature of such power that it could bring an end to her and the wolf's lives with but a thought. The wolf leaned in and drew a deep breath of her scent, his teeth gleaming in the ghoulish light. She couldn't help but flinch, an instinctive reaction to a predator in such close proximity to her.

"You're afraid, love. I know you are. You are such a beauty like this. Such a rare, special treat for Him," he growled into her ear, and she felt his hand brush over her purple-furred belly before cupping her mound. A moment later, his middle finger pressed between her labia and into her effortlessly, aided by the slickness of her arousal. Mukki let out a low moan, feeling a thrill of pleasure run through her as the large digit slid into her, curling slightly. The wolf's lips moved to her neck and he delivered an almost gentle nip to the soft flesh just above her collarbone, drawing out a squeal that was more ecstatic than pained. As he began to draw his finger back out and shove it back in, his other hand lifted to grope her right breast. "How many times have we practised this, hmm? How long have we been waiting to do this? And tonight... tonight it's real."

Mukki shuddered and gasped out, "D-don't remember. Lost count, Tiro." The wolf, Tiro, lazily fucked his middle finger into her over and over, just far enough to press the heavy pad of his fingertip against the deep bundle of nerves there. "Oh... oh fuck, Tiro, do that more." Her heart was beating rapidly in her chest. Tiro was right, she was afraid, but that only made her more aroused. One mistake and the summoning could go awry. But they'd practices this... enthusiastically... at least twice a week for the last year. The leyline convergence that would give the summoning its power would happen in just an hour.

"Imagine, Mukki. You make such a special treat. You letucian bats, with that purple fur, and the four ovaries, oh, He wants you all. And you'll be a succulent treat," Tiro growled, adding a second finger to the first that he was fucking her with. She was dripping wet now, to the point that her pleasure was spattering onto the floor, where a reservoir and grooves would carry it across the indentations within the pattern there. "Are you ready to summon Him? The One Who Grows?"

With the last sentence, Tiro pressed a third finger into Mukki, stretching her almost uncomfortably wide, then used all three to start roughly fucking her. Despite his leanness, Tiro had a powerful arm, and the dull ache that accompanied the pleasure just made the sensations more intense. Her response was lost in the wet sounds of Tiro's fingers shoving into her with punishing speed, his growing growls of excitement, and her increasingly strident cries of mingled pain and pleasure.

Tiro had found Mukki five years before, when she'd been only twenty and a student at one of the more formal magical institutions, and in that time he'd taught her everything he knew about magic. Her raw power had grown almost exponentially in that time, and she'd found in him a kindred spirit. Danger, sexual magic, and strange creatures were guilty pleasures for the both of them, and so this wasn't the first time by far they had skirted danger. Tiro was older than the lovers she preferred, but they hadn't sworn themselves to a bonding, and so she'd been free to take other lovers. And he was so good at what he did. Just the right sort of force in his rutting, in the way he treated her, but never going over the line to hurting her. His hot breath spilled over her ear as he growled, "Should I make it a fist, Mukki? You've done it before."

The words were enough, and she felt her walls flutter and clamp down hard on Tiro's fingers. Her cries grew louder and higher, and the half-scream she let out was high-pitched enough to make the wolf's ears splay out. A splash of her pleasure soaked the wolf's fingers and dribbled to the floor, mingling with the fluids already filling out the inlaid runes. Wincing, Tiro commented, "Fucking hell, girl... I love getting you off, but when I do it hurts my ears."

As she came down from her climax, Mukki was panting, her whole body shuddering with the force of it. "Y-you like it. I know you do," she gasped out. Her inner walls were still twitching, occasionally squeezing hard on Tiro's fingers in a sort of aftershock. "God. We... we're really going to do this. Oh god." The terror of the realization made her blood turn to ice as she realized that if their offering was not accepted, her life would end. If it was, then they would have an artifact laid within her womb of incomprehensible power. At the same time the idea itself, and the fear it inspired, made her arousal return with even more force than before.

As soon as Tiro noticed that her arousal hadn't been quite been sated yet, his lips curled into a wide, happy tongue-lolling grin. Slipping his fingers out of Mukki, he touched her cheek, smearing the fur with her own juices, and looked back into her eyes. "We are. And it's got you dripping," he growled and then leaned down to kiss at her right nipple, broad tongue flicking out. The touch was electric, making her arch her back as best as she could. He wasn't wrong, though. The danger of what they were doing that night was part of what made it fun for her. But it was something even more than that, a dark fascination with the 'what if' of it all. For their years together, they had played some very dangerous games that would have ended up with both of them dead, or worse. In many ways, the 'or worse' was what she'd been seeking all her life, even before she'd had Tiro to stoke the fires of that dark desire within her.

Even as the bat reflected on their previous adventures, her half-lidded eyes saw that he was kneeling in front of her now. "Y-you're not going to... oh god..." she gasped. The more excitement, the more of her nectar that spilled upon the floor here, the more power would be given to the offering. As the wolf's broad tongue began to lap across her soft purple furred mound, the strong tongue pushing between her labia and then pressing at her clit, she began to let out small cries of pleasure once more.

Mukki writhed in her bonds, the chains rattling as Tiro's hands came up in an effort to hold her still. He wasn't trying to be surreptitious or quiet, like the few times that they had fucked in the old libraries as they sought out old rituals and books of power left long forgotten. No, he was being noisy, letting droplets of his saliva and her pleasure fall from his muzzle to be collected by the grooves in the floor. His thumbs came up and spread her petals to reveal the pale lavender-pink inner flesh and the lip of her vagina. "You tell me when you're going to come, dear. Much as I love your taste, it's not for me."

The bat's already dim vision went blurry and her eyes rolled back as Tiro shoved the wet, flexible muscle deep into her, curling it slightly. "F-fuck... oh god, T-tiro, this is d-dangerous," she gasped, bucking against the wolf's ministrations to her depths. With his nose pressed up against her mound, he had no need to keep it spread, and he let go. One hand moved up to stroke across her belly, touching a small inscribed pattern right over her womb that he had cut only days ago. She hissed a little at the touch on the sensitive marks, only barely healed, but it was only a brief moment, and then his finger was moving down to massage at the tender nub of her clit. His other hand was making short rhythmic motions much lower, and she only barely had the presence of mind to remind him, "T-tiro, you can't... it'll s-spoil the r-ritual... oh... oh shit, fuck, going to, Tiro, s-stop, I'm going to c-ah-AHHH."

Tiro was prepared this time, his ears pinned down against his skull already. The moment her shrieking cry of ecstasy resounded in the room he pulled his tongue out and moved his head away then spread her labia like he had before, always enjoying the sight of her release. Mukki was trembling from head to toe, and from his vantage point, the wolf could see the pulses of her pleasure as her now quite messy mound nearly gushed a half dozen splashes of her pleasure onto the floor, though much of it dribbled onto his own cock, now fully erect.

"F-feel bad you can't paw off, Tiro, like the other times," Mukki whispered when she finally came down from the orgasm. He'd loved fucking her when they'd practices the ritual, but given that tonight was going to be the real thing, he had to hold back. He had gone a month now without a moment's release, because it had to be saved for the ritual. Saved for tonight.

That was because tonight, they would summon the avatar of an ancient god known only as The One Who Grows. It had been said in the old texts that it was a being that residents of the area had summoned once a generation in order to bless the wombs of their women, the seed of their men, and the grain in the earth. Each time, it had required the life of a female and a male who had not yet borne offspring. It seemed to prefer those with highly active reproductive organs. Sometimes, as much as half the time, the offering was refused and the female torn to shreds, and if The One was particularly displeased, the male as well. But, more often than not, it was accepted, sometimes with incredible gifts to the land and people. A seed would be laid within the womb of the female, a seed with the potential to grow into a massive tree. The sap would be a panacea for all ills, the fruit plentiful and nutritious, growing even in the harshest of winters. But for almost two centuries, the ritual had not been performed, the old faith wiped away by two genocidal wars and its people forbidden from observing the rites. It had almost been forgotten until two mages, herself and Tiro, seeking that knowledge had finally unlocked the secret of summoning The One Who Grows. She and Tiro had seen the potential in the seed. If they could provide the right sort of offering, they could claim the seed and the power it held without completing the ritual entirely. The last act of sacrifice would be for them to mate, for the fertile seed of the male to be spilled within the female. They would simply not take that step.

It had started with teasing between them. Exploring what was needed for the ritual, even practising the steps. All the while she and Tiro had been exploring other dangerous things. One time a year after meeting him, they had almost met their end with a deathvine. She had been drawn into the plant, and had watched another one grab Tiro, one that had been hidden. Mukki remembered that day. The realization that she was going to die had inspired in her complete terror... and an excitement that went far past what any sane individual should feel. If not for a passing adventurer, she and Tiro would have died that day.

Mukki tested her bonds, knowing that just the memory of that day had her getting just that much more excited. Instead of scaring her off as it should have, ever since then she and Tiro had played at more and more dangerous scenarios. "Tiro? Th-this is the one, isn't it? It's... it's going to end badly for me," she breathed out, voice quaking.

The wolf grinned and collected up more of her pleasure in his fingers and smeared them on her cheek. "Probably," he murmured, then leaned in to kiss her, his tongue pressing against her lips. When he pulled away, he gave her a firm nip to the lower lip, enough to draw just a tiny bit of blood. She could see that the sound of her cry at the sudden pain made his cock twitch. "It's up to The One Who Grows to decide if you're worthy of a seed for the tree."

As Tiro looked into Mukki's eyes, he shook his head, "Can you imagine if we'd never met? You'd just be in that old dusty library still. Reading about all the twisted gods and their rites."

"So boring. I think I returned too many books with sticky pages," Mukki said, grinning weakly. She was about to say something else when the room began to flare with light, the sickly and pale orange flaring to a verdant green. She felt warmth on her arms and legs, and knew that some of the light in the room was coming from the arcane markings there. Others inscribed into the thin flesh of her wings sprang to life, and a searing pain marked each one of them. Like so many times before, the bat's heart began to hammer in her chest, fear washing over her in a wave. With it came a deep arousal equal and perhaps even greater than that fear. It was time.

Tiro stepped back to the opposite end of the summoning circle, dropping the robe to the ground. His own arms and legs were inscribed with similar symbols to Mukki's. He called out in the old tongue, the ancient language of The One Who Grows' followers. It was a guttural and harsh language, but there was a simplicity to it that Mukki had always admired. She knew even as he called out the words what he was saying. 'We summon you, Old Father and Mother. Lord of things that grow, within us and without. Your blessing has faded, and we beg you for a new one. We come here, offerings to you, knowing that your blessing requires a gift of life, a gift of seed! Seed for a seed, life for many more!'

The whole while, Mukki's fear grew. The One Who Grows would know. It would know their intent, their purpose. This was a god, of true power, of old magic. This was stupid, insane, and she would die, torn to pieces bit by bit. It would devour her soul when it knew the truth. She caught Tiro's eye, shaking her head slightly, urging him to stop, but he continued on. His right hand drew lines of magical green light within the air, a beacon across reality itself that would call to the old god. His left began to stroke almost lazily at his cock as he intoned in the old tongue, 'Her pleasure and willingness is marked upon the stone. Within you can taste her potential. I offer my own as well!'

From the tip of Tiro's cock, a steady stream of pre was dribbling down onto the inlaid pattern. The danger and the fear made her own excitement so intense that more of it dribbled down from her onto the floor. With wide eyes, Mukki saw both start to glow with that same verdant green that seemed to suffuse everything around them. "Oh fuck... oh fuck..." she whispered with a low, terrified stammer in her voice. The One Who Grows was coming to them, and she could feel the weight of its power, primal and raging with the essence of pure life energy. The liquid of their mingled essence spread through the pattern within the floor, somehow filling every bit of it, despite there not being nearly enough of either. Tiro's voice was growing more excited now, as if he couldn't believe it was actually happening. They were going to do it, they were going to get a seed. 'You taste it, oh great Old One! No drug, no induction. Our desire and excitement is pure! No life sparked within us or by us. The only life to grow from us will be your blessing! We offer to you our lives so you may return to this world!'

Her eyes wide, the danger of her situation making her arousal spike even more, Mukki watched as the twisting and curling lines of glowing green changed. Where there had been grooves filled with green light, vines began to grow, rising from the floor and growing before her eyes. She looked toward Tiro for encouragement, and saw her own excitement and fear mirrored in his eyes. He was just as aroused as her, his cock seeming to throb as strange flower buds grew from the tips of the deep green vines. There was something else in his eyes, something that Mukki couldn't quite place, something she'd never seen before.

The vines writhed and waved in the air, seeming to defy gravity. The only source of the green light not inscribed in the runes in Mukki's flesh was now a rough circle in the centre of what had once been the summoning circle, the vines seeming to grow out of it. The pattern itself had disappeared completely, the stone floor as smooth as it had been the day that she and Tiro had first stepped onto it. Tiro kept stroking himself, shivering from head to toe as he felt himself grow close to his peak and drawing back before he reached that point. If he spilled his seed now, they would both find their lives suddenly and painfully ended.

As if drawn to the light of the markings upon her, a number of the vines reached for her. Thin and sinuous, they first wrapped around her wrists, then around her ankles, their passage guided by a slick film that coated each of them. One snaked around her neck twice, joined by another a moment later, and they both teased at her lips. She opened her mouth to let them in, her tongue flicking against their fibrous length, an invitation to explore more. To her surprise, there was a sweetness to the slick film upon them, but unlike with other similar experiences she'd had, she felt no tingling or hint of chemicals to accompany it. Moment by moment, she felt her heart hammering in her chest. One indication of reluctance, one taste of anything that The One Who Grows thought was impairing her judgment, and she would die. It had to have a truly willing sacrifice before it would deliver its seed to them.

Vines stroked across the thin flesh of her bound wings, and she squirmed as more and more of them began to probe the rest of her body. The ones curled around her legs slithered upward and were joined by two more, wrapping around each limb a half dozen times. She was growing increasingly more helpless, to the point that even if she hadn't been held in chains, she'd be unable to escape. She and Tiro had stepped past the point of return in the summoning, and were in more danger then than they'd ever been in.

She felt vines wrap around her breasts, first the right then the left, the tips flicking at her nipples. She cried out in surprise at the sudden sharp pains. As she felt the vines tighten all around her, she remembered her own part in the ritual. For just a moment, she hesitated, wondering what it would feel like to spoil the ritual, to feel the vines grow violent and hungry. The texts had shown vicious thorns sprouting from the vines and tearing into flesh, drinking in the offering's life's blood in payment for offending The One Who Grows. It was only a moment, though, and soon the words spilled out of her lips in the same ancient tongue that Tiro had spoken in. 'Please Great One, honour me with your seed. Take from me the sources of life within and grant in return your seed. Taste of me, taste my need. My womb has had no other life within. Let it bear only only yours!' Mukki wasn't sure if the ancient god could actually hear the words, but they were a necessary part of the ritual, the wording precise and unchanged in all the accounts that she and Tiro had found.

All at once, the vines grew even more animated, their tips starting to exude a slick nectar that smeared her rich purple fur with pale green. The vines wrapped around her breasts tightened their grip and began to rub and tease her nipples with their tips, leaving them stiff and sensitive, glistening with the slick green nectar. She let out an excited groan when two of them dipped between her labia and another teased under her tail, pressing at the tight ring of muscle there. The two that were at her mouth dove in and she suckled on each in turn, gagging a little at the unbelievably sweet taste of the thicker nectar. She had to show enthusiasm for all of this despite her fear, she knew, and despite that taste, or the ancient god would reject her offering.

Three of the vines with flower buds bloomed before her, the petals inside a kaleidoscope of blues, yellows and purples. What was more interesting were the stamens that sprouted from them. Long, tapered and covered with tiny bumps, they were about five inches long and an inch and a half wide at the base. They were literally dripping with the same lubricating nectar that the other vines had been coated with. Mukki gasped out excitedly, "Yes... yes! Please!"

As if in response, the three flowers descended upon her, guided by the vines that enwrapped the bat. Just the sight of them was almost enough to make her reach her peak once more. The first to reach her lifted to her mouth, giving her a chance to inspect it. The stamen was slightly curved along its length, with the very tip sharply curving upward. As it pressed at her lips, she once again opened her mouth, wrapping her lips around it. As it pressed in, her senses were assaulted by the cloyingly powerful sweetness of its nectar. To her surprise, it was having an effect on her; she could feel everything with an intensity that she'd never experienced, powerful enough that she knew it wasn't natural. As the bumpy length glided across her lips, she felt each and every nodule upon in exquisite detail.

The other two went lower, and she hollered around the stamen, her sight cut off by the petals of the flower as they closed on her face. The first pressed in under her tail, and it was a surprise that there was no discomfort in the penetration. She only had a moment to consider that when the third drove itself home, parting her labia and pressing deep into her. "My God, this is incredible," she heard Tiro say, his voice tinged with the ache to breed and with something else that would have felt unsettling at any other time.

The curved stamen spread her open, just thick enough that she could feel the nodules along it stimulating her. Unlike the two in her other holes, though, it seemed to be able to tell that this was the proper place, and instead of simply settling within her, once its petals kissed her own it pulled back and shoved forward again, twisting slightly. Again and again it did this, and she felt herself trying to twist and squirm to help it find the right way to stimulate her, though just the feeling of the nodules rubbing everywhere within her was almost enough to drive her wild. It was only when the sharply curved tip touched upon that sensitive bundle of nerve endings deep within her that she screamed in ecstasy around the stamen in her mouth. Her inner walls clenched and pulsed, squeezing down hard upon the stamen.

'Yes Great one, taste her need. Taste her devotion! Sup upon it to show the truth of her offering!' Tiro yelled, his tone wild and excited. It was more fervent and enthusiastic than anything that he'd said yet that night.

Mukki felt herself starting to gush in her climax, but the flower seemed to soak up her own unique sort of nectar. She felt all the vines shudder in unison as The One Who Grows tasted her, tested her, verifying the truth of the claim that she had not borne life within her, that she had not been induced to this with any drug or aphrodisiac. The offering had to be uncompromised, to know what she was offering to do for the ancient god. What was to come next was what Mukki had been looking forward to more than anything; the expression of gratitude that it would show to her for the offering made.

Everything went still for a moment. All she could hear was the thumping of her own heart and Tiro's excited, panting breaths. And then, all at once, the vines began to move, and the stamen within her began to fuck, pulling out so only that sharply curved tip was within her before driving back into her with punishing force. She felt the one in her rear twisting and squirming, and the one in her mouth did the same, but neither was outright fucking in the same way.

Thin little vines teased at the top of her cleft, seeking her clit. When they found it, they pushed and prodded and massaged it, making the nub of sensitive flesh stiffen until they could roll it between them. Mukki whimpered and yelled around the stamen in her mouth, and it wasn't long before she felt another orgasm rock her body at the stimulation.

The vines at her breasts did the same as the ones stimulating her clit, pressing and twisting and rolling the stiff flesh, a delightful feeling that just deepened the bat's excitement. Every single movement seemed to be geared toward her pleasure, and it wasn't just sexual stimulation, either. The vines were gliding all over her, pressing in different places, exploring and probing. Where they found tightness or stiffness they massaged and squirmed, working out tension in places that the helpless bat had not even known were tense. They even began to tug and pull on her tail, sending a thrill of delight up her spine.

The stimulation was intense, the most incredible experience she had ever had, and in no time she came again, with the flower hungrily drinking down her nectar. She found herself enthusiastically fellating the stamen in her mouth, tongue curling around it, reciprocating the pleasure she was being given without even thinking about it. When the next orgasm crashed through her, she knew that there would be so many more to come...

Mukki lost track of just how many times she was brought to her peak, forgetting everything but her need. But when it finally came to an end, when the petals of all three flowers drew back and, in unison, pulled out of her, she let out a sound of protest, a hoarse croak of 'more' coming from her. The buds closed over the stamens and withdrew back into the pool of green light. Many of the vines retracted and disappeared as well, until not a single one held her. Four new vines rose from within the light and poised in the air, seeming to wait patiently.

It was Tiro that saved her, brought her back from an error that would have spoiled the ritual and damned the two of them, a low bark of "MUKKI NOW". She blinked and fought against the lassitude that had come over her in the wake of the intense experience. She nodded, and then croaked out in unison with the wolf. 'Thank you great one, we beseech you for your seed that we may bring a tree of life to this world.' It was done, then, their part in the ritual complete. Now, they would find out if they had done it right, if The One Who Grows approved enough to give them a seed. Mukki knew that if it did, the experience would be traumatic and painful, but it was vastly preferable than if the ancient deity was displeased.

It was only the space of a few heartbeats before the four vines all dove at her sex in unison, their speed so startling that Mukki let out another squeal of surprise. They all met at once, their smooth tips slipping into her and stretching her painfully wide. Individually they weren't very thick, but combined, the writhing mass of vines was easily twice as large as the shaft that Tiro kept stroking every few moments. As they drove deep, she felt them probing and prodding, prying her even wider as they pulled outward. She gasped and let out a low whimper that turned to a strangled cry. It was too much, it felt like they were going to tear her open. Oh god, what if that's what they're going to do? What if it knows we're going to try to steal the seed? She could see the apprehension on Tiro's face, his excitement all but gone. She could imagine what she must look like, with the vines holding her cunt almost agonizingly wide, her pleasure dribbling out even in her pain.

That thought, that she may have gone too far, that she and Tiro had taken their quest for more and more magical power and greater dangers to its inevitable end, nearly brought her over the edge one final time. The danger, the fear, even the pain, they were delightful for her, her natural curiosity and thrill-seeking turned perverse. What did bring her over the edge was the sharp pain within her as one of the vines invaded her womb while the other five pulled her even wider. The sound that pealed from her throat was one of utter bliss and agony as her vaginal muscles tried to clench but found themselves unable to.

Everything went completely still, the sound of Mukki's piercing scream reverberating in the chamber. It faded into complete silence. Tiro didn't even draw in a breath, even stopping the lazy motion of his paw. There was a sense of something waiting, something considering. The only sound then was a soft dripping sound. The bat's sensitive nose detected a coppery scent in the air, and she realized then that she was bleeding, her life's blood mingling with the honey of her arousal.

Then, the four tendrils pushed deeper into her, and she began to scream again. They had invaded her womb, prying open the inner barrier of her cervix with no thought for her comfort. Intense pain bloomed within her and her vision blurred as tears formed in her eyes. She'd known there would be pain, she had known the process would be unpleasant. She had thought herself prepared for it, but as the searing pain of the vines' invasion went deeper, she found herself calling out to Tiro for help. She bucked and writhed in her bonds, but could do nothing but feel the thorny vines that held her dig in deeper.

Even in the old text, she had seen that binding had been used on the willing sacrifices. There would be no way to stop the offering from writhing and trying to break free, animal instinct overriding even the most steadfast devotee to The One Who Grows. Now, the bat knew just what that would feel like. She felt four wrenching sensations within her, each one like a punch to her gut, and she knew that It had taken from her what she and Tiro had offered. The source of life within her. All four of them. Their purpose complete, she felt the vines tug out of her. She was bleeding even more now. Some part of her was happy that her vision was too blurred to see what It had taken out of her as the vines disappeared into the circle of light.

Mukki let out a low sob. It was the price she knew she'd have to pay, but Tiro had assured her that the power of the seed that It would bestow on accepting her offering would be such that she could have what she lost restored to her, and so much more. There was more to come, though, a fact that she was reminded of as a huge shape came into view. When she blinked away her tears, she saw a massive flower bud, easily as big as her torso.

"Oh my god, Mukki, we did it. Oh thank you, thank you," Tiro breathed, and there was a peculiar sort of reverence in his eyes. His muzzle was open in a wide, tongue-lolling grin and his tail was wagging excitedly. She didn't know why, but there was something in his tone and his posture that unsettled the bat.

With a rustle of leaves, the flower bud unfurled, revealing vibrant, blood red petals with black striations that looked like veins running through them. At the centre was a long, bumpy stamen as thick around as Tiro's cock, but it was what was at the tip of the stamen that made Mukki's fear and excitement flare anew despite the throbbing agony in her belly and loins. Round, fist-sized and covered in hard little nubs, the seed loomed before her. Before she could say anything, before she could prepare herself, the flower angled itself toward her sex and drove forward.

The angle and direction were perfect, the thick and unyielding seed shoved against her already stretched passage with punishing force. The bat cried out anew at the invasion, unprepared for just how rough the laying of the seed would be. Implacably, lubricated in her own blood and the slickness of her arousal, it forced itself into her inch by inch. She could feel each and every nub dragging painfully as it slid into her. As it was forced deeper, a cry pealed from her lips, though it wasn't nearly as loud as those she'd already made, her voice already ragged from their violence.

"Oh, Mukki, this is wonderful," Tiro whispered, and this time he didn't disguise the absolute reverence in his voice. Something within his tone screamed a warning at her, but it was far too late for her to put a halt to any of this. Inch by agonizing inch, the seed was carried deeper into her, until she felt a pressure within and she knew it had reached the tortured ring of her cervix. And still the pressure grew, an ache growing. It felt like the seed was pushing against that painfully abused inner gateway for hours before, with a rending sensation, she felt it forced into her womb. She had not thought she could scream anymore, but the tortured sound that came from within broke something in her voice and it turned into a high pitched rasp at the end. It wasn't even a few more seconds before Mukki felt rather than heard the strange snapping sensation, and when the stamen retracted, the seed was not upon it.

Mukki tried not to look at the stamen, tried not to see what coated it, but the bright red smeared all over it was not unexpected. The vines and the seed had done real damage to her in the most intimate of places, and even with magic, it would take her a long while to recover. But her ordeal was finally over. She was finally finished after what had seemed like hours. They had done it. They had taken the seed of one of the oldest creatures in their world or any other.

The bat felt relief wash over her, but some smaller part of her felt a strange sort of regret. Some of the thrill of all these dangerous risks was the knowledge that someday she would step past a line of no return. The incident with the carnivorous plants hadn't been the only near miss. If she had to admit, there was a dark fascination and even desire to know the moment when she knew for complete certainty that her adventures into deeper and more dangerous forms of debauchery were at an end.

The flower returned to being a single huge green bud and withdrew into the circle of green light, and it faded entirely, plunging the chamber into darkness so complete that she thought she might have been struck blind. She tried to let out a little screech to try and see if Tiro was anywhere in the chamber now, but she couldn't even bring out a whisper.

A soft glowing yellow light appeared in the centre of the room, held aloft by Tiro as he approached. "Oh, Mukki. My dear," he whispered. "I do this for the greater good." He was stepping forward, his cock held in his hand. "If I had told you that this was the real point all along... would you have followed me?"

Mukki stared at Tiro in confusion, not sure what the wolf was saying, but growing increasingly worried she had an idea. "Tiro, let me d-down. WE did it. We can steal the magic. It can't come if we don't summon It. We're in the clear. Tiro, w-what are you doing?" The wolf had stepped up to her, and rather than lifting his hand up to undo her bindings, he began to stroke the tip of his cock against her abused mound. "Tiro what are you doing?"

"Two centuries, Mukki. Two centuries since the last offerings. The empires that destroyed the old faith... they're all gone now. Our number were so low. I'm the last, you know, the last that remembered The One Who Grows. My uncle taught me," He reached his hand up to fondle her right breast and rolled the thick nub between forefinger and thumb, all the while rubbing his cock against her mound.

The fear returned in full force, and Mukki whispered, "Tiro, don't. I don't want to..." Her voice was urgent and horrified. But her desire betrayed her, and despite the pain, despite the terror; indeed, because of both, she felt herself growing wet with more than the blood that still dripped from within her.

"Yes you do, Mukki. I know what you crave. If I couldn't find someone who believed as I did, all I had to do was find, in all this world, one whose dark desires could be stoked. Encouraged. Tell me to stop, tell me right now," Tiro growled as he leaned forward and laid the tip of his cock at the lip of her vagina. "Hundreds of lives, Mukki. Thousands. My people lived here for hundreds of years, making their offering to It. Happily. Think... think of the gift you can give my scattered people. A beacon to them, that the old ways have come again."

Eyes wide with shock, she understood now the fanaticism, the reverence. Tiro had always intended them both to be the sacrifice. As she felt the head of his cock pressing in, she gasped. "Tiro," she half-pleaded, "We... we'll both die..." So many times before the bat had imagined what fate would eventually befall her. That Tiro would be there with her at the end hadn't ever been in doubt. In their years working together they had rarely ever done anything separately. But that Tiro would be the one making it happen? As his cock slipped deeper, Mukki let out a final whimper of protest.

Tiro leaned his muzzle over her right shoulder, holding her hips as he began to rock his own, letting out low gasps and moans as he felt her warmth around his shaft. After a few moments, he pulled himself back until just the tip of his cock lay within her. "I know, Mukki. I know. I've wanted this for so fucking long. My uncle, he taught me everything he could. He said I wouldn't find someone to do the ritual."

"Oh god, Tiro," Mukki croaked, truly understanding it all. It had always been building to this. The wolf had targeted her, having found out somehow of her dark fascination with death and danger. He'd stoked its fires in her, tried to get her closer and closer to the point of no return, all in preparation for this. Trusting in him to work with her to get them out of every dangerous situation. All so he could get her here, so he could spill his seed on the gift of The One Who Grows and sacrifice himself and her. And as he slammed himself into her aching need, she knew she wouldn't leave the chamber alive. And with realization came a powerful climax that drew out a wheezing scream of ecstatic pleasure.

Within the dim chamber, illuminated only by the tiny ball of light, the only noise for the next few moments were the grunts and whines of Tiro as he rutted, and the desperate terrified sounds spilling from Mukki's throat, and the wet sounds of sex. "Tell me to stop. Tell me not to tie with you. Tell me. I'm so close, Mukki. Share this with me."

The wolf's whole body was shaking with his desire, his need. But when he moved to look in to her eyes, she could see he was serious. The wolf would stop, and it would destroy him to do so. In the heat of her passion, in the grip of her deepest fascination, seeking that single moment where she could never go back, she thought of what would come from their coupling. The first Tree of Life in two centuries. Fruit so plentiful it could feed hundreds in a day, its massive branches sheltering within its shade those whose minds were broken so they could find peace. Diseases healed. A people reunited as they hadn't been for so very long. She couldn't bring herself to speak the words, and so all she could do was give the tiniest nod.

Tiro pressed his lips to hers then, and this time, he didn't hold himself back. Hips bucked, and though she thought her own endurance depleted, Mukki felt herself pressing back against hers. She could taste his breath, feel the warmth of his body as he bucked his hips. Every second brought them closer to the end, but the two lovers no longer cared. They sought it, embraced it. The thick bulb of Tiro's knot began to kiss at her passage and she felt the pain of his cock battering that abused and torn flesh within. He'd always been too big to tie with her, too long, but not this time. Hanging in the chains that held her, Mukki reflected on the life she'd led. It had been a good one. Then, with a popping sensation, she felt him sink deeper, the tip of his cock invading her womb. The bulb of flesh swelled, and she felt him tense. He howled his pleasure into her mouth as his cock began to spray his seed into her. He'd been edging himself for so long, there was so much of it, and it coated the hard and round seed within her.

The moment it happened, Mukki felt her own body begin to quake and shiver as one final, terrible climax rocked her body. She didn't scream, she didn't cry, she just gasped into the wolf's kiss. There was no going back now. No escaping what was to come.

Within her, from each and every tiny nodule on the gift of The One Who Grows, tiny vines began to grow, over a hundred of them. Each was tipped by a single, sharp barb. She felt the first stabs of them as they tore into her flesh, and each drop of her blood was taken in and absorbed. She heard a strangled whimper come from Tiro and he jerked his head back. "It's in my cock," he groaned, and then it became a shriek of pain.

Mukki had thought that the pain of having that seed lain in her, of having the source of life torn from her, was terrible, but this... this was so much worse. And when this pain ended, she knew, she would find out what came next. Searing pain blossomed within her belly as the new vines tore through flesh. She felt a tearing in her belly and looked down to see that they had torn out from her navel, the flesh underneath writhing, and sunk into Tiro.

Down her legs and through her chest, even up her neck, her veins a pathway the vines to follow, cutting through her, feeding on her life's blood and her flesh both, she felt the blooming pain move everywhere. Her heart was beating faster and faster, not in terror, but in a strange wonder and excitement. She was past fear, there was no point in it, no need for it. She was even past resignation. She knew that her sacrifice would help hundreds or even thousands.

It was agony beyond anything she could ever imagine. It was something undeniably beautiful. She looked into Tiro's eyes one last time and saw in them a gratitude and, to her surprise, love. She coughed, and saw her blood spatter onto his chin. She mouthed words she couldn't speak, for the vines were in her throat. 'Kiss me'. Their lips met, and she felt the vines tear tongue and palate as they moved from her into Tiro. It was a sort of horrible intimacy so deep that few could ever experience, and only ever once. She could feel her heart labouring now, the pain so all consuming that it was meaningless.

Thump. Vines tore her lungs, tore her flesh, dozens of them emerging from her everywhere now, and from Tiro as well. Five seconds passed and still they grew.

Thump. There was no pain anymore, at least beneath her ribcage. She was locked into her kiss though, and couldn't see why. Ten more seconds.

Thump. A hundred vines that had sprouted from her, gorged on the life of her and her lover, buried themselves into the stone, and up through the rotting timbers of the ceiling.

Thump. Stillness within. And warmth and light within her mind. A soft voice calling to her, distinct words. Come rest with Me. You did not truly give of yourself until the end, Femukki, daughter of Letucia, but I knew you would. My child Tiro chose well.

Contentment. Her heart did not beat again.

On a hill near the old and dilapidated farmhouse, a hundred metres away from the cellar, an ancient, wizened wolf, hunched and gnarled, watched as the building exploded. Timber flew and stone geysered, and he felt pure joy at the sight. The old ways had come again. The people, scattered for centuries, would come from the far corners of the world, to rest under the branches of the growing tree.

He wondered about Tiro, a source of pride for him. But even more, he wondered about the other, the female that Tiro must have convinced to bring this about. How had he done it? Leaning on his staff, he began to approach the huge tree that had grown in a matter of minutes. He must be under its boughs when the others came.
