Diluc should have never entered the depths of the forest on his own. His father always warned that the world beyond their clearing was a dangerous place. Diluc had always been too curious for his own good and now, with winter on the horizon, the young flower fairy thought he might find berries and better flower nectar deeper into the woods. He was an adult now, surely, he would be safe…
Surely…
He’d been foolish to believe that.
Now, with vines wrapping tighter around his throat, all he could do was curse his ignorance.
He’d been flying along steadily, searching for the last berry bushes of the fall season. He’d been hopeful, collecting some tasty nuts along the way. Diluc hadn’t been looking up . Not until it was too late. A rustle caused him to look towards the canopy as a vine suddenly lashed out, plucking him from the air. It caught him around the middle, another from below caught his ankle, and still a third looped about his neck. His delicate wings fluttered uselessly. Though he immediately struggled, the vines held fast. His hands were still free, he forced himself to hold back the panic as he went for his dagger. Diluc lashed out, slashing at the vines, attempting to force them away.
The blade sunk deep into the vine’s flesh. Blue blood dripped from the vine, the substance was sticky, coating his dagger and hands. It was cold. The vine didn’t release him, instead it tightened it’s hold until he was barely gasping. He tried to keep cutting at the vine, attempting to saw at the one he’d stabbed but the lack of oxygen quickly made his vision go hazy. His hands slipped from the handle, on the verge of blacking out. Only then did the vine loosen its hold on his throat. Diluc took large gulps of oxygen gratefully, coughing as he desperately breathed in the sweet scented air.
“Now, now~ That’s not a very nice thing to do…” A teasing voice echoed around him. It was hard to pinpoint the exact location of the voice, between the dizziness and the panic, Diluc found it difficult to focus his thoughts.
“Such a cute fairy… What are you doing so deep in the forest, don’t you know there are things waiting to eat sweet morsels like you~?” From above, a dark figure began to lower until Diluc was face to face with a much larger creature.
A vine monster.
Diluc had heard of such creatures… But he was confused at the sight of the distinctly male appearance. He was under the impression these creatures took feminine forms to lure male humans… Certainly they could be dangerous to a smaller flower fairy like himself but he shouldn’t have been the preferred prey.
“L-let me go…” Diluc attempted to sound strong but with the vine still around his neck, he couldn’t quite get the anger into his words. His hands raised, back under his control. He pushed at the vine around his waist. It was thick and strong, the cold vine didn’t budge even an inch.
“Now, now~ Why the rush to escape?” The creature came closer and now Diluc could see it in all its glory.
Dark blue vines faded into tan skin at the monster’s waist. Strong muscles and wide shoulders led up to a handsome face that could have been human if not for the star shaped pupil in its singular eye. The other eye was hidden by a large blue flower. Matching hair spilled over the creature’s shoulders.
“I-I need to return to my clearing…” Diluc hoped the monster would have some sense of sympathy, Diluc was still a young fairy and so much smaller… “I won’t make a good meal, please…let me go…” Diluc’s pride was nothing in the face of the dangerous creature who grinned with such sharp teeth.
“Oh precious little thing…” A large hand with blue claws stroked his face. Diluc forced himself to stay still. “Pretty thing…” The large creature’s face came closer, that sweet scent growing stronger.
Diluc’s eyes were drawn to the flower. It was so large and smelled so sweet…each petal was dusted in pollen- His eyes went wide. He immediately shut his mouth but it was too late, he’d inhaled enough pollen that his body was already beginning to feel warm. The creature’s grin grew impossibly wider. More vines suddenly wrapped around Diluc, coiling around his body and pulling his arms over his head. The vines slipped beneath his clothing, seams ripped and soon he was bare. The creature’s blue eye raked over his form, making the fairy shiver.
“So pretty~” the creature leaned in close, fingers moving rub Diluc’s pointed ear, “You have a lovely voice… Ah- I almost forgot to introduce myself~ I am Kaeya. I wonder how you will sound screaming my name~ ”
Diluc could only let out a single desperate scream as he was pulled up into the canopy. The only sign he’d ever been there were the shreds of his clothing and the fallen dagger littering the forest floor.
---
Kaeya carried the struggling fairy through the trees until he reached the cliff-face he called home. There, amongst the rocks, hidden by the thick canopy, was a comfortable cave. He settled with his vines spread around them. Diluc desperately looked around for any opening for escape. The scent was so much stronger here. His body felt far too warm, his skin was tight and itchy, only the places where the cool vines touched felt relief. His mind was already becoming addled. Monster pollen was a dangerous thing. Diluc knew what it meant, even as his mind so desperately rebelled against it. Whether he liked it or not, the thick, leaking tips of far too many vines told him exactly what he’d been captured for.
Breeding.
Thin vines wrapped around his thighs and ankles, forcing his legs apart. He was bare save for a single remnant of his leggings, now left as some ripped thigh-high, and his golden circlet. He shivered under the heavy weight of Kaeya’s gaze. The creature looked hungry as he took in Diluc’s bare form. A clawed hand came to rest on his chest. It moved down to his stomach, so large it could span his entire waist with one hand.
“So small and delicate…but fairies are resilient~” Kaeya’s words were a threat, but they were not a lie. The vine monster would not be the first to kidnap a fairy for such things…but Diluc had never been taken before. He’d never even laid with one of his own kind before! Despite his fear, Diluc could only pant helplessly as heat stole his reason. The more he panted the more pollen he breathed in and the warmer he became. It was a horrible cycle.
The creature drew a single claw over Diluc’s straining cocklet. He whimpered. The creature’s touch was cool and pleasant, leaving him needy and desperate as much as the intoxicating pollen did. He felt like he was drowning. But the monster gave him no time to collect himself.
A thick vine rose in front of Diluc’s face. His cheeks burned as he took in the thick, phallic shape. It dripped with some milky fluid; the appearance was obscene. He pressed his lips together only for the vine to bump against them, smearing the thick liquid over his lips. It made his skin tingle. Every brush of it left his lips feeling sensitive and hot, as if it was turning them into another erogenous zone.
Kaeya stared down at him, smile turning mischievous as he took Diluc’s cocklet in hand, stroking over it insistently. The touch caused Diluc to gasp. The vine took full advantage, plunging deep into his mouth before he could put up further fight. It was so thick that he couldn’t even get a good bite. The fluid spread over his tongue, sweet and thick. It robbed him of his reason, making his throat tingle with every gentle thrust. Everything was going according to this monster’s plan. Diluc whined around the mouthful, drool spilling down his chin as the vine thrust deeper. It breached his throat, choking him, and yet pleasure overwhelmed his body. The fluid made him so sensitive, each thrust felt as good as if it had been inside his hole.
“Pretty thing~ That’s it…just let me shower you with pleasure~” Kaeya purred. He waved his free hand, two more vines appearing. These were thin with odd clear cup-like flowers. Diluc didn’t realize what they were for until the thin vines wrapped around his nipples. The clear flower buds attached to his chest and sucked.
They were suction cups…
The tiny vines tugged and teased his nipples while the flowers sucked on them. He arched his back, moaning around the vine still pumping sweet fluid into his stomach. Kaeya continued to stroke Diluc’s tiny cock. The fairy’s shimmering wings fluttered helplessly. He could escape this place. The pleasure was too much for Diluc’s inexperienced body. He spilled hot, thick liquid over Kaeya’s hand. The vine fucking his throat pushed as deep as it could, leaving him choking as it spilled a deluge of thick, sweet, sap like liquid into his stomach.
His entire body felt like he was burning up. Every part of him tingled. His toes curled, his wings fluttered, his hole clenched around nothing. But this one orgasm wasn’t enough for his body. Not with the intoxicating sap in his stomach, not with pollen still thick in the air.
Diluc blinked open his teary eyes in time to see Kaeya lick Diluc’s cum from his fingers. The creature had a long blue tongue to match the blue eye and blue flower. Diluc shivered.
“Delicious…but not enough~ I want to taste more of you, little fairy…” Kaeya’s voice was thick with desire.
It must be the breeding season for this creature. That was the only way this made sense to Diluc. He had been unfortunate enough to get trapped…and now he would have to satisfy the creature's lust before he had any hope of escape.
His traitorous body didn’t seem to think this was such a bad idea. His cocklet twitched despite his orgasm.
“It seems your body is honest~ Don’t worry, I’ll give you much, much more.” Diluc could only offer a sweet moan at Kaeya’s words.
More vines appeared; the number of vines seemed so endless to Diluc. Thin vines surged up Diluc’s thighs to explore his lower body. They flicked his balls, coiling around them, others began to press and tease his rim. He sobbed as they breached him, mind rebelling against the thought that his first time was being stolen by vines. The horror was overwhelmed by the pleasure. Slowly but insistently his hole was stretched by the multitude of vines. Inside him, they coiled together to create a proper cock. It was thick and textured in just the right way to force more pleasure onto his body. The vines rubbed his prostate and pressed deeper. Ever flexible, they pushed into his colon, providing pleasure a normal cock would never be able to give him. He was being ruined for all others by this creature. How was he supposed to want others when he knew this pleasure existed?
He moaned and whined and drooled. His body was utterly shameless no matter how the situation burned his mind. There was no room for rebellion when he was being drowned in such a sweet abyss.
Another orgasm was wrung from his cocklet, leaving his mind blank as he shook in the monster’s hold. The vines coated in his essence went to Kaeya’s mouth, the creature licking them clean as well. It felt as if he was consuming Diluc’s cum intentionally. The thought had little time to take hold before the thin vines began to slip from his hole.
They didn’t all leave. Several hooked on his rim, forcing his hole to stretch wide. The vines holding his thighs tipped his hips up so that Kaeya could see his twitching, puffy pink hole with ease.
“You are almost ready…such a beautiful hole for such a beautiful fairy.” Kaeya pressed his fingers into the fairy’s hole. “I have been watching you, little fairy~ So brave as you edged deeper and deeper into the forest with every trip… Such a naughty thing you are, Diluc~”
He didn’t have time to process the creature knowing his name. Not when some of the tendrils slipped up his cock to circle the tiny slit at the tip. His eyes went wide. He couldn’t even shout as one pushed inside. Did this creature truly intent to violate every inch of his body-
One vine turned to two and two to three. Three tendrils were fucking his cocklet. The pleasure was something he’d never even thought possible…especially as the tendrils reached a deeper point near inside. The pleasure went blinding, vision whiting out. When he regained his senses, he was overwhelmed with the need to pee. Nothing could come out…not with the vines settled firmly in his bladder. He could feel them poke and prod his bladder from the inside…could see them as they pressed up, causing small bulges on his lower stomach.
“Why…? ” It was the only thing he could ask, a shuddering gasp the best he could manage.
“Why?” The creature seemed to contemplate his question, “Because you are beautiful~ A sweet red flower…perfect for me to pollinate, a perfect seedbed.” Diluc wanted to cry. Whatever hope he thought there would be in escaping vanished. This wasn’t breeding season…the creature wanted to turn him into a breeding farm.
Diluc went limp in the monster’s hold. There would be no fighting. His mind could no longer hold on with this new knowledge. Tears spilled down his cheeks. A cold hand cupped his face, wiping his tears as the creature moved over his body.
“Do not cry~ I will cherish you. I will give you so much pleasure…you will never have to think of anything ever again. You need only think of me…only call my name, only call out Kaeya. ” The creature finally gave its name. Kaeya’s thumb pressed into Diluc’s mouth, pinning his tongue. “In this sweet voice, I only want to hear your moans and my name…”
Diluc wasn’t given much choice in the matter, not when a thick cock-like vine pressed against his stretched hole. It was ribbed, each bump scraping against his insides. He couldn’t see it past Kaeya’s body, but it felt massive. The weight of it settled within him. It seemed to fill every gap.
Kaeya’s long tongue stretched out. He held Diluc’s mouth open as his tongue slipped between Diluc’s lips. He leaned closer, sealing their mouths together as his tongue slid into Diluc’s throat. The kiss was intense. Kaeya wrapped his large hand easily around Diluc’s throat, feeling how his tongue bulged the fairy’s delicate throat. It matched the way his vine bulged Diluc’s stomach.
Kaeya shivered with pleasure as his vine fucked into Diluc. He could feel the pleasure from each of his vines, could feel how warm Diluc was inside, could feel every twitch of the fairy’s hole clenching around him. The connected consciousness meant Kaeya didn’t miss a single bit of Diluc’s pleasure. From the way his vines fucked Diluc’s bladder, making his urethra even more sensitive with the aphrodisiac sap it was filling his bladder, to the vines teasing Diluc’s nipples to the point they swelled red and almost painfully tender. Kaeya felt every moment.
Diluc groaned around Kaeya’s tongue as the thin vines holding his rim open pulled even further. He ached but the pleasure overwhelmed any pain. Or perhaps that was the pollen- Diluc could hardly keep track. Still, he was stretched wider – his eyes flew open in horror as a second large cock-vine pressed up along the second. It strained against his rim but his body only put up a token resistance before the second vine breached him. Diluc felt like he was being split in half. This wasn’t possible- His body surely would break-
But he didn’t.
The sap that he’d been fed by the first vine was changing his body without his knowledge. He was growing soft, skin becoming elastic, muscles weakening… A seedbed didn’t need strength…
The second cock sunk into his body. The twin cocks fucked him deeply, invading places within him that he never even imaged could feel pleasure. Kaeya’s tongue stole his breath, leaving him to drool helplessly. Subconsciously, Diluc sucked on Kaeya’s tongue. Everything felt good. Everything tasted good. Everything smelled good. He was drowning in sweetness. It eroded his mind, forcing him to forget everything else. All that he had been didn’t matter when he was being immersed in pleasure.
The cocks scraped his insides, they rubbed deep inside, they tested his limits and then pushed past them. When Kaeya finally pulled back, Diluc was able to look down at his body. His stomach bulged with each thrust. They stretched his skin, punching into him. He felt like something in his mind was breaking. Seeing his body being used in such a way…
He moaned and sobbed with pleasure, needing to cum but the tendrils fucking his tiny cocklet prevented him from ejaculating. He could see that his bladder was bulging, filling with sap from the vines. Diluc was overwhelmed with the need to piss…it made everything feel even more sensitive. He couldn’t articulate around the endless moans being forced from him. All he could was gasp a string of pleas that seemed to fall on deaf ears.
He felt the twin cocks within him stiffen. They thrust faster, abusing his sensitive spots until his body couldn’t take anymore. His spine arched as a dry orgasm rushed through him. The pleasure left him blind and deaf, the world fading to a white haze. Dimly he could feel as hot liquid poured inside of him. It was hotter and thicker than the sap filling his stomach and bladder. This settled heavily inside him, thrumming against his insides with the force of a raging river. When his senses began to return, he could see how his belly bloated out, sagging from the sheer amount of cum inside of him. Surely this was the monster’s cum…there was no other explanation.
Diluc trembled, worn out from the three orgasms that had been forced upon him. His stomach creaked from the pressure, but the two cock-vines prevented him from releasing the fluid.
A large hand rested on his stomach, rubbing his swollen abdomen in a way that could only be described as lovingly.
“Now you are ready for my seeds~” The monster purred. Diluc felt panic bubble up. He was already filled with cum…what else could there be-
Diluc wasn’t given much time to react. A vine shaped differently from the others rose between Diluc’s thighs. The tip was shaped like an unfurled flower bud. The rest of the vine was filled with bumps.
Seeds.
Each seed seemed to be a little bigger than Diluc’s fist…the problem was the vine itself. The vine was almost as thick as his thigh-
“N-no…w-won’t fit…” Diluc shook his head, panic was trying to build despite the pollen’s influence.
“Hush~ It will fit…you have been thoroughly soaked in my sap~” Kaeya ignored Diluc’s pleas.
More horror seared through Diluc’s heart as the two vines fucking him didn’t leave. They simply spread apart, forcing his hole to stretch. The tiny vines were no longer needed, they left the larger vines to hold him open. These vines were strong enough to ignore any resistance his hole might put up. The seeding vine nudged up against his stretched rim that leaked thick, pale, creamy cum. It pushed in alongside the twin vines. Diluc tipped his head back with a scream as pain laced up his back. It was quickly dulled by a flower appearing in front of his face. A puff of thick pollen was sprayed almost directly up his nose. Whatever sense he’d gotten back melted away, leaving him pliant once again. His body was horrifically stretched. His hips creaked from the thick vine forced inside of him. His cum bloated stomach was pushed out further by the seed-vine.
It sunk deeper and deeper into him, pulling back only a little to thrust deeper each time. The motion reminded him of a snake… It crept through his body until he could see the bulge pressed up to the base of his ribs. He felt like he couldn’t breathe.
Once it was seated deep within him, the other two vines began to move deeper, coiling around the seed-vine. The thrust back and forth along the seed-vine, fucking his body while the seed-vine remained still.
Kaeya drew Diluc’s attention back to his tiny cocklet by pressing over the bulge that was his bladder. He whined, eyes hazy and mind lost to the intoxicating pollen entirely.
“See~? There is nothing to fear…I will never let you feel pain…you only deserve pleasure.” Kaeya cooed, massaging Diluc’s distended bladder. The tendrils worked their way out of Diluc’s cocklet one by one. Kaeya didn’t let him release the sap right away, he placed his thumb over Diluc’s urethra, stroking his cocklet.
As the monster forced more pleasure onto his body, Diluc felt something shift just under his ribs where the tip of the seed-vine sat. He felt it shift… then he felt it grow. The flower was blooming inside of him. It unfurled petal by petal until it created its own bulge. He struggled to breathe under the pressure it put on his diaphragm.
“Beautiful thing~ Now I will make you mine… ” Kaeya cooed, finally removing his thumb from blocking Diluc’s slit.
The sap rushed up Diluc’s incredibly sensitive urethra. It was thick and slick, the pressure forcing it out at a fast pace. It was like his cock was getting fucked by the sap spilling from him. His urethra gaped open slightly from getting stretched by the tendrils. As the pressure lessened, the mix of sap, urine, and cum drooled from his stretched cocklet. He was ruined…
He hiccupped. The seed-vine had begun to release its load within him… Each seed was as big as his fist, settling deep inside of his body. They came out with force, thudding inside of him. They forced hiccups and coughs past his lips. The seed-vine slipped from his body inch by inch as it filled the space it left behind with seeds. It seemed like an endless supply. Through out the process, the twin vines fucked him roughly.
Diluc’s body was wracked with pleasure. He came again, watery cum dripping from his overworked cocklet. His stomach was becoming something obscene… His belly stretched out, the seeds visible as round spheres beneath his skin. His stomach creaked, forced to accommodate the mind-boggling number of seeds. If it weren’t for the sap, he surely would have burst from the amount inside of him.
Kaeya’s hands rubbed Diluc’s gravid belly. The pressure he placed on Diluc’s stomach only added to the pleasure. His touches made the seeds roll around inside of Diluc, pleasuring him further.
“Beautiful…I knew you would be the perfect seedbed, little fairy…” Kaeya purred.
The almost forgotten tendrils abusing Diluc’s nipples finally pulled away. He almost gasped in shock. His once tiny nipples were now thick nubs, flushed a dark pink. They were so sensitive that just being exposed to the air made Diluc’s shiver. Kaeya leaned in close, taking one bud into his mouth. He sucked, licked, and even bit the sensitive nipple. He rolled the other between his clawed fingers.
Diluc wished he could faint. His body couldn’t handle any more pleasure… But the pollen didn’t seem to allow for such a reprieve. He was forced to just accept the mind-breaking sensations.
The seed-vine finally reached his rim. The flower closed once again, now it was much thinner after spilling its load inside of him. His stomach was stretched to look nine months pregnant with triplets.
But Kaeya still wasn’t done.
The twin vines, which had been fucking him the entire time, began to spill within him. But this time, the fluid was different.
It was cold.
Diluc broke out in shivers as the cold liquid filled him until his stomach was no longer lumpy from the seeds. His stomach creaked loudly as if it was going to finally burst despite whatever the sap had done to his body. He didn’t even look pregnant at this point…he looked grotesque. And yet the pleasure it forced on him caused Diluc to cum once again with tears blurring his vision. Blissfully, this time…when he spilled, the world faded to black.
---
Kaeya laid the sweet fairy on a beautiful large blue blossom. The vines kept his legs spread so Kaeya could see his puffy, gaping hole. The seed gel had solidified nicely, keeping the fairy stuffed full. It would dissolve in a week…then Kaeya could enjoy watching his lovely seedbed release everything he’d stuffed him with. Then the cycle could continue.
Kaeya curled around the sweet fairy, rubbing his distended stomach. Perhaps the flowers that would grow from the seeds within Diluc would produce fairies… Kaeya was eager to find out~
