Work Text:
Castle Town was positively empty.
As Kris descended from the supply closet, the eerie silence was the first thing they noticed. Not a single denizen rushed to greet them thus far, and even Ralsei himself appeared to be missing. Proceeding with caution and drawing their sword forward, they got prepared to face something big.
Training grounds, remade in the style of a chess board already, didn't even have a dummy standing. The Great Door appeared pristine, and Sweet, Cap'n Cakes' shop would have looked fine if it wasn’t for its door being forced open and all the records going missing. Did a thief manage to sneak in here?
Kris continued to the main street, slowly turning their head from one side to the other in search of, quite frankly, anyone or anything capable of solving this riddle. Yet, the soft blue lanterns in houses was extinguished, doors to colorful shops refused to budge and even dojo seemed like it was abandoned suddenly. Bracing themselves for a more sinister discovery, they then turned to the castle. The Grand Fountain cast its mighty shadow still, undisturbed by such petty issues like its children disappearing for good.
To their surprise, torches inside were lit, though it went without saying that there was no one to enjoy their light. The prison missed not just Kings but even cages holding them, and King of Spades' cell showed some signs of a struggle. Kris took a deep breath, clenching to their sword even tighter. As slim of a chance as it was, they should have searched for him from the beginning: if some villain did invade Castle Town, its ruler and guardian was the only person capable of repealing them – and the first one to get hurt protecting the innocent.
Forsaking any caution, Kris rushed to Ralsei's room proclaiming his name – until he crashed into someone by the ladder, losing their balance and falling on their rear.
"K-Kris?" they heard a familiar voice exclaim.
"Ralsei?" fear in Kris' eyes immediately parted for relief as they jumped to Ralsei and locked him into an awkward embrace he returned. When they tried to smile at him, however, they noticed a look of concern written on his face.
"I am glad to see you, Kris," he finally responded, struggling to come up with words. "I thought you will be leaving on a trip with your family for this week?"
"They refused to take any chocolate, so I was out," Kris shrugged. "Speaking of being out… where is everybody?"
Ralsei averted his gaze.
"I relocated them for a time. And, honestly, I believe you should leave as well."
"Wait, what?" Kris looked bemused. "Why?"
"Not that I don't want to see you!" Ralsei corrected himself hastily. "It's just not the right time for… being together. Oh, that sounded even worse, didn't it?"
"Just tell me what's going on," they sighed.
"Well," Ralsei drawled, inviting Kris to follow them to the empty courtyard. "You do know that monsters are made half of blood and half of magic, right? And that their bodies function a little bit differently, compared to yours?"
Kris nodded.
"We, Darkners, are similar in a sense," Ralsei continued. "We have originated from the primordial darkness itself, and I can't even begin to describe what an intricate process it is. Regardless, there is one crucial thing you need to know: as someone made in the image of a monster, I am much more intricately familiar with the magic Lightners once possessed. Kris, do you, um, remember when your brother hit puberty?"
Oh yeah, Kris did all too well. The very moment Asriel got half an inch over them, he couldn't stop joking about 'weather down there' or his 'adorable little sibling'. A few nice bites to his arm were enough to end it, fortunately.
Kris froze for a moment, contemplating. Monsters did have a second puberty thought to be associated with their magical half – was it what Ralsei tried to explain to them? They did sleep through that class back then, but Noelle helped them to sort things out before the test. Basically, monsters had much more fluid forms when they still could channel magic. As their affinity for the craft grew, so did their bodies to contain and mend it – dragons were not a mere legend after all. While magic was inaccessible now, it still multiplied not unlike cells, forcing unexpected and sometimes rapid grow spurts in adults, though most of them couldn't hold a candle to the beasts of the past.
Asriel outgrew their father just a week after he finished the school, hitting his head at most door frames, and at their graduation Kris was unmistakably the shortest one; even Temmie boasted a slightly taller stature as she stood before the lectern to give her speech.
Only then Kris finally noticed that they were tilting their head ever so slightly up this entire time. Ralsei smiled awkwardly.
"So that is why I… insisted for people of Castle Town to leave for a safe place. I fear I could have harmed them, even if by chance."
Kris blinked, confused.
"Even if you'd grow like a few feet, there is no chance of you hurting anyone. Besides…" they moved to Ralsei and whispered in his ear. "I like tall boys."
A part of them expected Ralsei to grow a little bit from this compliment alone, though it probably wasn't very realistic. Instead, he simply blushed, and his lips curled themselves in a weak smile.
"I appreciate it, Kris. But… do you realize that I receive my magic from the Grand Fountain itself, as well as that I don't posses a Lightner's biology to stunt my growth? This might turn rather unbecoming rather quickly."
"The bigger only means better, right?" Kris joked, squeezing his paw. The next moment, however, they saw it for themselves.
At first, it seemed like Ralsei shifted his balance to the tips of his toes, gaining just an inch or two of height for a brief moment. Yet, other changes came with that as well. His paws, although it was even less noticeable, definitely grew in their hands; his fingers were always a little bit shorter, but not anymore. His fluffy ears, his eyes, his horns – his entire being was expanding subtly, gaining ever more of an edge over them. His clothing, however, could only shrink, revealing his knees and his wrists, usually concealed by now dwindling robe.
"It happened again, didn't it?" Ralsei trembled, hugging himself. "I do advise you to leave, Kris. For your own safety."
Instead of doing anything rational, Kris grabbed Ralsei's slightly larger paws even firmer.
"No, I won't left you alone. Not anymore."
Two completely opposite emotions appeared on Ralsei's face: a clear disapproval mixed with a sincere gratitude. He contemplated his response for quite some time, and, before he got a chance to actually say anything, Kris kissed him quickly, betraying a coy smile.
"Figured it'd better while I still can reach you," Kris said evenly as their eyes sparkled with mischief. "Come one, I've got an idea to kill some time."
They led completed perplexed Ralsei to his own bedroom, almost fighting to make his stiff legs move. Judging by the fact that some of their trophies were carefully stored away, with others occupying their usual spots, he was in the middle of securing the place before they interrupted him. Oh well.
Kris landed on Ralsei's spacious bed, inviting him to come a little bit closer. But, before he could sit by their side, Kris pressed their hand against him and commanded.
"Not now. Get undressed."
"Huh?!" Ralsei frowned in disbelieve, a cluster of conflicting feelings taking over. Luckily, Kris was reading him like a painfully familiar book, the one they could recite with their eyes closed.
That protective nature of his was caught in a struggle against his unadulterated lust, and behind kindness, sincere no doubt, poorly-hidden desire could be seen in his pale scarlet eyes – especially so in their presence. Kris was acutely aware how often Ralsei was checking them out, and could only speculate on what he did in his free time with all the photos they made. They tried multiple times to stay with him alone, but natural kindness never allowed him to ravish Kris on the spot, much to their discontent. They were sure of him being the most vile creature in either light or darkness, and they finally got a chance of proving it.
His total inability to read social clue perhaps played its role as well: he would have never initiated any intimacy until requested directly, with compliments or suggestions flying over his head like wind. There was something cute to it, truth to be told, but they didn't start this relationship (six whole minutes ago) to hang out with another bottom to discuss teacups. Besides, they knew that his entire demeanor of a submissive servant to their wishes was far from the whole story. Ralsei enjoyed bossing them all around, and, if they were completely honest, there was a pretty good chance he could have outright defied such a request to keep his pride intact. Or he could have teared their own clothing instead to teach them a lesson, Kris didn't really mind; after all, it wasn't like they came here completely unprepared.
As they were busy studying Ralsei's expression, it happened again and was slightly more apparent this time around. His entire body sprung up, like his spine straightened after years of bad posture, and his shoulders stood somewhat wider. What was more intriguing, however, was a small bulge appearing around Ralsei's crotch, his once spacious robe shrinking that much already.
If Ralsei noticed anything, he didn't show it. He hesitated at their request still, with some fur on his face turning completely red. Kris sighed, standing up.
"Let me help you a little bit…"
Then, they stuttered. Standing perfectly still, Kris found themselves at the same level as Ralsei's neck as their eyes stared somewhere at his upper chest. Surprised by this sudden yet expected revelation, they tried to step back and fell on the bed again.
"Kris!"
"I'm fine," they shook their head, leaning on Ralsei for support. "So, um, are you gonna do it? I want to check you out as you grow."
He tilted they head down as Kris approached, nervously licking his lips.
"Well," he began uncertainty. "Only if it's a scientific interest you have in mind…"
"We could fuck as well," Kris shrugged, grinning. "Though there is probably little time for this."
Once again, Ralsei was caught in perfect balance between opposing emotions, with lustful longing, genuine affection and utter embarrassment blending together in an expression even Kris had difficulty understanding. Finally, he conceded.
Ralsei attempted to remove his robe swiftly, but perhaps underestimated how much that thing shank: it stuck at his collar, and muffled groans could be heard through the fabric. Kris chuckled at the sight, realizing that Ralsei was struggling for real only a moment later. They came to his aid with the most efficient solution possible, tearing the robe apart to create more space, and soon enough Ralsei was before them in his naked glory.
While dense white fur obscured his figure a little bit, Kris would definitely call him attractive. With an hourglass-like shape leaning more toward wider shoulders, lithe build with no less muscles than a monster should have and large padded paws made for hugging, Ralsei was more that cute.
Observing his body like it was genuinely an experiment of sorts, Kris moved Ralsei to the center of the room for a better view. His adorable little tail was twitching in panic, and, as Kris walked behind him, they noted impressively-sized balls he couldn't hid behind his paw there. As not to alarm him too early, Kris refrained from smacking his plump butt; they did discard their own armor though, keeping on only the skin suit.
They took the initiative yet again, forcing Ralsei's paw away from his crotch and revealing his member to their lustful gaze. If its size could be contested before, now it appeared to be on par with Kris' own package, long since erect and staining their cloth. They interlocked their fingers (his were bigger already…) and, as a tease, quickly rubbed their member against his, giving an impish grin away before going for his neck. Ralsei shuddered, and his smooth member twitched in excitement before growing right before Kris' eyes. They thought it to be another surge at first, but the answer turned out to be much simpler: Ralsei wasn't even half-erect yet, and he just gave in to his feelings.
Avidly embracing Kris, Ralsei grabbed them in a passionate kiss and forced his elongated tongue inside as his paws were squishing their hips and moving them ever so closer. A strong smell of marshmallow mixing and what felt like burned cotton candy consumed Kris completely, leaving them unable to do anything but moan into his lips.
They thought they were ready for an unconditional surrender, but Ralsei kept surprising them over and over again: as he gently pushed them on the bed, Kris found themselves caught between Ralsei's hand as his snout grew closer to their face, only desire hidden behind his beautiful pink eyes. Wishing to stop his assault not, Kris turned on their belly and wiggled their fat rear suggestively, inviting him for a treat. Ralsei, from his part, took it too literary. Grabbing Kris' butt and revealing their needy hole through torn fabric, Ralsei lowered his snout to give it a taste before he began savoring them earnestly, salivating and crawling deeper with each passing thrust. His warm, moist tongue was absolutely nothing like toys they tried before, eating them out with truly admirable hunger.
Their malleable skin recoiled at his touches, muscles of their once unviolated rim unable to halt Ralsei's advances and pushing his slick tongue deeper. This new sensation proved to be too much to Kris, with muffled groans escaping their lips as they took a large pillow for support. The embrace waned as quickly as it started however, with Ralsei now kneading their behind and leaning in to give a smooch to their ear, provoking deep blue blush in its wake. Meanwhile, his painfully hard member was too busy teasing their most sensitive part, leaving dirty trails on the suit's pieces.
As Ralsei tightly hugged them across their chest and leaned over, Kris could sense their erratic heartbeat losing the last of its restraints. Yet before they had a chance of getting anything done, it happened again.
Kris felt the weight on their back adding up suddenly as his embrace grew painfully stiff, like Ralsei was struggling with controlling his grip. A few moments later Kris, realized that they were completely covered by his shadow, and even his breathing seemed deeper, louder. While they were more that content to continue, Ralsei recoiled back, a mask of fear painted on his face. He leaped from the bed, perhaps hoping to make a distance, but Kris quickly followed – and froze in place, gazing up.
Just a day ago, Ralsei was around the same height as them (maybe even shorter, though that was probably a wishful thinking), and now small goatboy's shoulders stood higher than their crown, leaving little room for a debate. Awestruck, Kris was leering over visibly uncomfortable Ralsei, absentmindedly caressing his forearm.
"I… I really worry for you, Kris," Ralsei said, breathing out. "I fear the growth is becoming more severe with each time…"
"I can manage myself alright," Kris chuckled. "But if you are uncomfortable with that, I won't insist on splitting me in half."
"Kris!"
"Relax," Kris put their hands up in the air. "It's just a scientific curiosity speaking. I still didn't get to explore your body, remember?"
Ralsei nodded cautiously. And with that, Kris attacked.
Pressing Ralsei against the nearby wall, they began massaging his flat chest perhaps too firmly, kissing his rose nipples hidden in a forest of fur. Some of it stuck in their mouth when they went for a bite that made Ralsei finch, yet again blessing them with an intoxicating smell of sweets.
They could feel Ralsei's erection between their bodies as it was humping against their torso, doing nothing but fueling mutual lust. Ah, teasing the poor boy was too much fun: Kris made exactly three steps back and removed whatever was left of their clothing, turning around to sway their hips. Angel, they enjoyed how Ralsei struggled to function in their presence. On the contrary, however, one particular part of his was throbbing in desperate need of their assistance.
Kris knelt before his member, giving it a few playful strokes. They somewhat struggled to get their grip around his shaft, almost as thick as their own arm; if some powerful magic managed to force it down, it would hang almost to his knee. Was his growth disproportional, or did he pack even before? Kris didn't really care, devouring it with hungry eyes. Caressing his balls with a free hand, they helped themselves to his base to leave a smooch right below his length. Body odor was especially strong there, blessing their nostrils with musk so overwhelming, it was almost intoxicating. For the moment the kiss was lasting, Kris felt nothing but enticing scent of candy.
Drunk on lust, they continued to shower the underside of his member with kisses, moving closer and closer to its tip. As if it genuinely was a piece of candy, Kris allowed their teeth a little bit of taste, which forced Ralsei to utter a pained wince. To make up for this, they gave him an especially long kiss then before attempting to embrace the thing whole.
They thought that they were doing quite alright: be that their practice with toys, his biology or simply magic, their reflex stayed silent. Right before they braced themselves to continue, however, they sensed something large and soft on their nape. A moment of awkward stillness – and Ralsei's paw dragged their head further down his length.
Gasping and chocking, they were unable to weasel away from his firm grasp, looking up pleadingly. Perhaps they didn't wholly comprehend how huge Ralsei has become already, but his face seemed now even more distant than the ceiling was from when they stood. And there was not a single kind emotion reflecting on it. Kris was forced right against his crotch as their throat bulged to create some space for this monster. Saliva was leaking from their wide-open mouth alongside with white droplets, and whatever was left of their voice couldn't protest even if they desired so. Touching their neck, they could feel it occupying any space it could claim.
Was it a petty revenge for biting on his dick? No matter his reason, they would not let go of control so easily, even if the image before their vision was turning blurry.
Hugging his hips, Kris slowly pulled away a little bit before returning back. Away and back, away and back. Each time, they got just a little bit more ground to breathe in his sweet odor as tears were streaming in their eyes. Struggling against Ralsei's dominating presence was unexpectedly arousing: uncomfortable enough to be an exciting challenge, but not so painful it would turn sour.
When they thought that their abused throat finally got used to such a treatment, they felt Ralsei's body shudder. No, no, not right now!
Kris' muffled protest was swiftly shut by Ralsei's growing monster pushing deeper inside their throat, forcing its muscles to recoil away in utter panic. To their relief, he let go of them almost immediately, and Kris made a run for their life. Falling below Ralsei, Kris couldn't stop coughing their lungs out while his member sprung to its newfound glory.
"Kris! Are you alright?" Ralsei leaned down to help them stay straight. They shook their head as they accepted his paw, somewhat confused by his question. Well, not exactly that: they were more surprised by his voice itself, sounding now audibly lower.
They stood next to Ralsei again, noting expected changes: now they were staring firmly at his belly, the tip of their head not even reaching his nipples. The most drastic change, however, wasn't dictated by this surge: when Kris looked up to meet Ralsei's gaze, he seemed to actually enjoy himself, free of any concern.
"You were amazing," he smiled, running his fingers through their hair; his paw was so large now, it could easily cover their upper back, let alone their head. When his hand moved to hug across their shoulders, there was only one thing Kris managed to utter.
"You are huge."
Gently pushed to his side, Kris planted a kiss below Ralsei's chest, embracing him across his back so tightly, they could feel his heartbeat thumping in their ears. He was so tall, they could barely lock their fingers just under his neck. His ridiculously swollen member was pressed against them, humping their hip.
"My boyfriend is huge," they repeated as a tease, lightly scratching his shoulder blades. "So big, so massive, so beautiful. How long before I'd be forced to climb you like a mountain? Before I couldn't even see your face from down here?"
Ralsei lowered his head, blessing Kris with a warm smile. They tried to cup his snout, only to suddenly realize that it was already too large to properly fit in their puny palms. Like he was expecting it, Ralsei chuckled before going for a kiss.
His enormous tongue had little issue invading their mouth as it embraced them avidly, making its way deeper and deeper into their throat. Chocking on his saliva, Kris managed to respond the best they could, desperate struggling with his overwhelming assault. On a brighter side, they were able to hug him across his neck, nuzzling against his snout and scratching the back of his head.
While Ralsei didn't sweat per se, their game was working him out, as ignoring his musk grew increasingly difficult. His sweet odor threatened to take over their entire being, coddling them and permanently staining them – not that Kris minded any of that. Eagerly gulping his saliva, Kris was humping against his thigh with no restrain, utterly and completely lost in these sensations. At last, they pulled back with a groan as they came, shooting rope of seed on Ralsei's body that was followed by pearly droplets.
Kris fell on their butt, breathing erratically and catching the air as if they were deprived of it for days. Their throat burnt like fire and their chest and belly were uncomfortably watery, still bearing his scent. The initial arousal receded, though not completely, and they looked at Ralsei with a newfound clarity.
He breathed heavily and, in turn, glanced at Kris with a predatory glimmer beneath their eyes. His painfully erect member throbbed, with even just pre leaking from it overshadowing Kris' load. A part of them was genuinely worried for a moment whether he would lurch forward, but Ralsei smiled reassuringly, still panting.
"I really… liked being so close… with you, Kris… If you want to stop here… we could…"
Yet, another surge cut him short.
Much more powerful and obvious, it stretched Ralsei's body with little warning, forcing his head against the ceiling with a loud thud. Pieces of stone were falling on him, provoking less than pleasant grunts, and Ralsei attempted to sit down – only for the floor underneath him to blossom with cracks. An inadvertent movement of his arm broke his bed in an instant, and whatever furniture stood in the path of his expanding legs soon shared its fate. Kris sat right between them, awestruck. With their size difference right now, Ralsei could fold his fingers against their entire body and carry them freely, using them as a stress-relief toy.
When the growth finally came to a halt, a shadow of his behemothic member loomed over Kris, shamelessly drooling on them. If they were to stand side by side now, they doubted whether they would even reach his crotch – and Ralsei head will crash through the roof in that case, quite literally.
A drop of seed that would have easily filled their palm fell over, damping their hair and getting to their eyes. They licked their fingers, tasting a strange mixture of salt, sugar and something they couldn't quite recognize still.
"Kris?" they jumped, not immediately realizing that this booming voice belonged to Ralsei. "Are you, um, okay? I can lift you up if you want."
"It's cool," they affirmed. "Actually, there is another thing I'd like to try!"
Before another drop of seed stained them, Kris moved to the other end of the room to examine something.
Their merry stroll to his feet took Kris three whole steps; it was not that impressive in the grand scheme of things of course, but they were surprised to feel any distance, at all. Could he, in theory, grow until his legs are longer than entire highways? Kris gulped, and their softening member pulsed again.
They slowly caressed his padded sole, enjoying its rough texture against their hand. It was still somewhat smaller than their body, but the very idea of being crashed underneath it enticed Kris more than they were willing to admit. Kneeling before his foot, they began carefully massaging it; not that they were especially skilled in the matter, but something told them that he would enjoy this kind of attention.
Suddenly, an inadvertent movement of his paw kicked them back as he roared with laughter, his another sole landing precisely on their body to cover their torso. They tried to move it away, grunting, but their scrawly arms barely managed to tickle it, judging by his faint giggles.
"K-Kris!" he called them. "What a-are you doing, ha ha?"
"Fighting for my life, probably," they said in a deadpan manner, realizing that the air around them stood heavier. Damn, it felt like they were trapped in a box filled with nauseatingly sweet marshmallow that threatened to squish them for good.
"Kris? Is everything alright?" they heard him calling again. Wasn't their brutally honest response enough? And then it hit Kris: Ralsei probably became so large already, he could have simply not heard them down there. They tried hitting his sole, kicking it and even moved their neck to bite his toe, all their actions proving quite futile.
They were ready to surrender their pride and finally call for help – and right this moment the weight on their body began swelling. Ralsei's feet stretched out and grew, crawling to deny them any vision and trap beneath themselves, permanently. Terrified to meet such an ungraceful end, Kris started hitting and clawing on his sole thrice as violent as before, and when Ralsei jerked it, only if for a moment, they seized their opportunity and rolled away.
They heard the room around them cracking and crumbling, and right as they were fortunate enough to make their escape Ralsei's soles crashed the wall and parts of the floor, hanging down to the second story. They jumped to his foreleg almost instinctively as the floor beneath them was coming undone with cracks, clenching to it perhaps too tightly.
"Kris?" he simply asked, his voice sharing a distinct echo. His head already went through the ceiling and perhaps managed to go through the roof, at least judging by the falling pieces.
"I'm fine!" they said loudly, trying to hold onto him; fur on his legs was so lush and dense now, it honesty wasn't that much of a challenge.
"Ah, that's wonderful!" they couldn't see his face anymore, though they were sure he was smiling. "Can you come a little bit closer? I think it would be much safer that way."
Kris had little objections here, slowly crawling to his thigh. Their gaze inadvertently ventured to check him out, and they swallowed audibly: despite somewhat placating, his monstrous erection was still throbbing in need of attention, and now it stood bigger than their entire body. Heck, Kris was pretty sure that they were as big next to Ralsei as a doll would be next to them, and they suspected that this was far from the last comparison they will make today.
As they attempted to climb above his pelvis, their foot slipped, and thus Kris landed precisely at his semi-hard member. They heard a low groan, but it was hardly dictated by discomfort, at least not entirely; it jerked up, forcing their very body along the ride. They felt another surge taking over him, and his member now loomed over them, both ready to attack and yet shielding them from any debris.
His fur between their fingers grew, and they felt their grip slipping again – as so they grabbed on his pulsating flesh in vain attempt to not get knocked over. Their face was pressed firmly against his head, white fluids leaking on their defenseless body as their tiny hands groped him. And musk, they were unable to escape his dominating, nauseating musk.
"I will try standing up here," they heard his booming voice. "Get yourself comfortable, alright?”
Kris could have sworn that they heard hints of irony, and then something large wrapped itself against them. It was his hand, Kris realized, that now covered them completely. They could barely see from here, but they heard the place around him coming crashing down; not just his room alone, the entire castle surrendered to Ralsei's overwhelming might, and the noise around them grew borderline unbearable, as if someone was demolishing a skyscraper just across the street.
When he finally removed his paw and allowed them to get a better look, they saw the castle half-destroyed and engulfed in dust, slowly and surely slipping into ruins; its walls were reduced to piles of broken bricks, its exquisite furniture was scattered around and its intimidating form now seemed almost toy-like next to his body. They had difficulties properly measuring him, but Ralsei should have stood no shorter than sixty feet by now. And then they noticed how the ground was still growing further and further away.
They squeezed his member with their legs as not to fall over, the entire thing outgrowing them to such a degree, they couldn't even interlock their feet below its base. That provoked what Kris initially assumed to be a thunder, but, obviously, it was Ralsei betraying one lustful moan after another as they were slowly climbing to the tip of his massive, swollen member twice as thick and thrice as long as their entire body. That was only an estimation of course, and a very outdated one at that.
His member was shifting, growing and expanding underneath their touch with each passing moment, and soon enough Kris realized that they had no chance of actually climbing him any higher, for they couldn’t have even spread their legs far enough to support themselves. Luckily, Ralsei came to their assistance with little hesitation, his paw gently pressing them against his flesh as he was stroking his length; mere minutes ago his hand was covering their entire body, but now Kris wasn’t sure they were even half as tall as it was long.
It was genuinely admirable that Ralsei had enough self-control as not to grind their pitiful body into a red spot on his pristine fur, his hand guiding them slowly and patiently. Through between his fingers, Kris saw that the ruins of the castle were now looming so far below they could have barely made them out, and in a few more moments they were gone, stomped into memories by Ralsei’s giant sole. He was enjoying himself, Kris realized, and something akin to fear flashed in their eyes.
Their body was guided to his tip leaking pre, the smallest droplets being no less than a few gallons to them, and there Kris hesitated for a moment. His thumb was holding them across their waist firmly, allowing their arms to awkwardly caress his member while their legs tried to find its footing on his foreskin. Soon enough it grew large enough to poke their face, his domineering musk coating them permanently as if his cum became their second skin. He might have muttered their name, they weren’t sure; his voice no longer registered to them as a sound they could have deciphered.
Nevertheless, the idea of pleasing such a giant transformed their worries to renewed vigor, their tongue making out with his gargantuan erection and swallowing much more than they could have had; in a minute or two, he would have become big enough for them to try crawling inside, and they weren’t sure they would be thinking anything by that point to restrain themselves. Meanwhile, their member was shamelessly grinding against Ralsei’s finger in their mock struggle of getting away, his fur ticking and teasing them only further. Escaping, of course, was a futile affair, for his pinkie alone would have been strong enough to squish them into nothingness if he so desired.
At last, Kris cried out and came again, Ralsei’s warm, sweet, beautiful scent replacing their air and taking over their mind, their body lifelessly drooling against his paw and swallowing more and more of his seed; they acutely felt their belly swelling pound after pound yet were powerless – and perhaps just a little bit unwilling – to get away. He was so ridiculously large at this point, Kris wasn’t sure he did not ascend to become a world in his own right. And at the very least, his own climax was truly earth-shattering.
Declaring Ralsei’s roar to be powerful would have been an insult; truthfully, Kris did not think they could have ever described such an expression of raw might in mere words. The darkness around them shuddered in terror, the ground underneath his feet Kris couldn’t even seen anymore trembled and his pulsating member shot up, ropes and ropes of his sweet, nauseating seed leaking below. It was the largest waterfall Kris has ever seen, and they had no doubt he would be able to engulf everything here, to properly claim his domain.
Just how much cum was stored in his gargantuan balls, each one bigger than the building of the local bakery long since crashed at his heel. Speaking of which, his massive ass would be more than enough to flatten their entire town back in the Light World – and could Ralsei grow big enough to overcome the divide and emerge on the other side? And if so, how long would it take for him to outgrow everything in their tiny world and move on, leaving behind nothing but his footprints stretching across continents and oceans?
They weren’t sure how much time have passed as they were laying on his padded paw, riding off these overwhelming sensations and struggling to breathe. Ralsei did not stop growing while they rested, and at this point they couldn’t even begin speculating whether he was a few hundred feet tall or already achieved a solid mile of height; stars were the only thing they saw through the gaps between his fingers. His heavy pats were akin to sudden bursts of wind uprooting entire houses, and, thought they suspected he tried to spare them the worst, the smallest movement of his hand made their head spin and the slowest of his heartbeat jolted their body in a manner far from unpleasant.
His growth came to a halt eventually, and he felt it was safe enough to move Kris a bit closer to his face. Still week in their knees and holding to their inflated stomach, Kris could not have possibly attempted to stand up and merely waited. As he revealed his paw, they were completely awestruck: his handsome, beaming face looked like a distant mountain to them, and they couldn’t quite make up some of his features even from that close. His fingers were towering over them intimidatingly, and his individual hairs were just as tall as Kris, sometimes even taller.
Wary of disturbing them, Ralsei refrained from speaking a single word, though that turned their moment rather awkward rather quickly. Well, he probably knew what to do next, and so relaxing against his rough pad was the best course of action for them to take. Kris sighed, not quite closing their eyes to observe him some more before departing to sleep. They were thoroughly wasted, but that did not mean they were against trying something similar in future. And though seeing their boyfriend that ludicrously massive was a rare treat, they hoped he could figure out a more manageable size.
Of course, provided that his body would remain much, much bigger than theirs.
