Chapter Text
"Well then, let's go in!" Itto suddenly grabbed his wrist which startled him from his daze and made him yelp. The oni hummed while dragging him towards the bath area and Aether stumbled on his feet and tripped multiple times, mind still vividly showing him that image.
When they arrived, he was greeted by the serene view of the steaming hot springs, surrounded by carefully placed rock fixtures and lush green trees. The clear water glistened under the moonlight and everything made for such a wonderful sight that Aether gasped in awe.
"Itto, this place is beautiful!" He tilted his head to the side to look at Itto.
The bright expression he had fell and turned into a deep blush while he smiled sheepishly. The towel wrapped on Itto's waist was gone, now slung over his shoulders.
...it's really… big…
"Like it?" Itto spoke, obviously referring to the hot springs as he unhanded the blonde's wrist and looked at him expectantly. Aether's mind was spinning so fast that he could only manage a weak nod—he couldn't even meet Itto's eyes but he seemed not to notice. "Right! Let's rinse first!"
It was at that moment that the short repose he had was cut short. Aether's predicament came crashing onto him like a large brick.
Itto walked over to the corner where the rinsing area was and hung his towel, took a wooden bucket and doused himself with water. Aether was frozen on the spot, contemplating on running away again while Itto wasn't looking because he knew that there would be no other chance to escape if he let this one go. He backed away once, twice, with careful footsteps to not alert the oni who was busy washing himself. Okay, I can do this. He was mapping out his escape route while walking backwards slowly, slowly, and— his heel caught against the uneven rock flooring and the next thing he knew, his vision was upturned and there was a painful flare on his ass.
He fucking slipped.
"— ow…" he winced.
The loud thud he made must have alerted Itto because when he had finally gathered himself and looked up, the oni was standing over him.
Just a few feet away from him was Itto and his exposed cock. Seeing it up close made him feel like he's almost having a heart attack. It wasn't even hard yet but — oh. Oh. D-did it just twitch?
Only when Aether looked up did he realize that he really messed things up.
Itto was eyeing the soft lips between his legs that were spread wide due to the position he landed in when he fell down. In the end the towel was never really a means to save him, not when he was the one who fucked things up from the start.
"D-don't look…" he squeaked. Tears began to sting his eyes from the sheer embarrassment of being seen.
"Hm? Look where?" Itto's eyes suddenly flew up to stare at his face instead. His semi-erect member and the faint blush he had was a telltale sign that he was definitely looking though. "You okay? Can you stand?" The oni offered his hand which Aether gingerly took, and he was effortlessly pulled back up on his feet in the next few seconds. "You should rinse yourself too. I'll go in first." His hand was released. Itto flashed him a wide grin before soaking himself in the hot spring.
There was no other way around it, Aether thought. If he let it linger on his mind this whole trip would become awkward. Aether thought he might as well salvage something and enjoy the trip. He took the towel off his waist and washed himself clean like his body was on autopilot, still a little bit ashamed from what just happened. Then, he followed Itto into the water, yelping when the water was hotter than he expected. The oni made a smug huff at him as he sat on a ledge unfazed by the heat, and Aether returned it with a glare as he lowered himself and waddled towards where the other was seated.
Once he was properly seated too, Aether leaned back, staring at the night sky and breathed a pleased sigh. "So nice…"
"Is it? How about a contest then?" Itto smirked. "Whoever can stay here longer wins, the first one to give up loses."
"Hm… what do I get if I win?" Aether asked, folding the towel and placing it over his head.
"Winner gets to ask the loser to do whatever they want. How about that?"
Suddenly, Aether was all ears. If he wins, it would be a perfect chance to make Itto do all his commissions in the Adventurer's guild for a week, a time he could use to earn more mora by working odd jobs. Not that he was confident in his skills, but if he could withstand the biting cold of Dragonspine, this was also something he thought he could take.
"Fine, you're on."
With that settled, their little competition began. The water reached only up to his waist while he sat but the rising steam warmed up his whole body as well. Being soaked in warm water combined with the tranquil atmosphere felt like the most rewarding thing after a whole day of running around for Aether. He closed his eyes and shifted to a much more relaxed position, basking in the heat that felt like it seeped even down to his bones.
"You're being awfully quiet." Aether remarked after realizing that Itto, was in fact being quiet when he usually wasn't.
Itto laughed at his words before speaking. "That's just how it is! In the onsen, we rest both our body and soul!"
"Mm… I see…" he mumbled. "I have much to learn about Inazuma culture, huh…" ' Including this culture of skinship and all that.'
Silence, except for the sounds made by falling droplets of water and crickets enveloped them. Both of them had no way to count how many minutes had passed but Aether was sure they had been there for a while.
And unfortunately, it was starting to turn uncomfortable for Aether.
Beads of sweat formed on his temples, dripping to his neck where they stopped at the valley of his collarbones. His chest rose with each pant he took, escaping from his pretty pink lips that were slightly parted. Wet golden hair clung to his body and contrasted with his pale and milky soft skin.
"Itto… haha… it's pretty hot, isn't it…" the words rolled slowly from his tongue. There was no taunting response from Itto which was unusual. "Itto…?"
Worried, Aether opened his eyes to check on him. Itto was sitting straight, arms crossed over his chest. His lips formed a crooked smile and he looked so tense for some reason. When his eyes trailed down, Aether understood why. He wished he didn't.
Itto's cock was at full mast, standing proudly in between his legs and curling up against his abdomen. Calling it a monster would be no exaggeration — it practically looked like a third limb. Just staring at it made Aether feel an ache deep in his stomach that his legs involuntarily clamped shut, making ripples in the water where the lower half of their bodies were submerged. And Itto, he was so large that half of it was poking out from the water's surface. It looked so red and the veins lining it seemed like it was about to burst.
The blush on Aether's face deepened and extended to the tips of his ears and down to his chest. Even though he was already looking away, the image wouldn't stop bothering him. His mind was filled with the thoughts of Itto's dick that he just had to sneak another look at it. Are those… spikes? He did a double take until he realized that yes, Itto's shaft had small spikes all over it. ' Look away… look away...' he kept telling himself but he couldn't. A bead of precum gathered on top of the bulbous head. Aether had also just noticed that the red marks along Itto's body also extended to his shaft. Without being aware of it, his eyes were following the line, up to Itto's face where he noticed that the man's eyes were looking down at something else as well.
His crotch. Itto was eyeing his pussy again.
That's when it clicked to him — Itto was hard because he'd been staring at his naked body ever since their little competition started. That's it. He knew he had to leave or things wouldn't end well for him.
"I-i'm going…!" Aether abruptly stood up and turned around. From behind him, he could hear the sound of splashing water as well.
"Does that mean you're yielding then? That I won this match?" Itto spoke, the pitch of his voice that Aether's shoulders jerked when he uttered his first syllable.
"Yeah… let's talk about your prize later when—" His words were interrupted when a pair of hands circled his waist. Itto held him so tightly that he couldn't take another step forward.
"No, I want my prize now. This won't go down by itself and surely you're not expecting me to walk out of here with a boner hanging between my legs?" The oni pulled him close. Aether felt something hard poking his back and when he recognized what it was, his heart began to beat wildly. "C'mon, bend over." Itto pushed and urged him to kneel on the ledge despite his protests.
"W-wait! I can just s-suck you off!" He negotiated. Aether quickly got his rejection when he felt Itto's fingers roughly spreading his pussy apart, making a moan leave his mouth. "Itto...!"
"Oi, I'm not called the greatest for nothing." Aether felt the blunt cock head prodding his hole and his panic shot up further, causing his eyes to tear up. "I'm not gonna settle for anything less. Now, open up and I'll—"
"ANOTHER CONTEST! P-PLEASE…!" The blonde nearly screamed. Itto stopped trying to push in, looking at him with curiosity. "I… If I can make you cum without putting it in t-then I win… I want you to leave me alone…" Aether paused, trying to slow his breathing but to no avail. He was so nervous he felt like he could choke. "B-but if I cum first then… y-you know… you can…" Finally, he broke. The tears he was trying to hold back spilled out from his eyes.
Itto erupted into a bout of hearty laughter. "Another hurdle, huh? Fine. This just makes the prize sweeter." He squeezed Aether's legs together and slotted his cock in between his inner thighs, just under the plump lips. "After my win I'll use your little pussy and I won't stop even if you cry and beg."
"Ngh—!"
Itto pulled his hips back very slowly, making sure that Aether could feel every ridges and bumps against his cunt before snapping his hips forward. The force of it made a loud smack on Aether's ass that he loudly yelped but the oni spared him no time and continued rutting on his thighs. After a solid minute, he could feel his whole body burn with arousal. The way Itto's barbed shaft rubbed on his pussy had his mind clouded with haze that he almost forgot he shouldn't cum first.
"You're so small! I wonder how far my dick will reach inside you…" Itto taunted, pressing a hand directly under Aether's navel. "Here?" He slowly trailed his fingers up and pressed the area above the belly button. "Or here?"
"Mmnh…! Ah! Itto… nnnh! ♡"
"Guess we'll find out soon."
When he realized that he was moaning, Aether bit his lower lip in an attempt to hold the sounds back, afraid of egging Itto on. The last thing he needed was for the oni to speed up and increase the friction on his cunt. However, his body was starting to betray the facade he was trying to put up. He couldn't pretend that it wasn't getting to him when his thighs were involuntarily twitching or when he was dripping copious amounts of slick that showered Itto's fat cock. "Don't cum" was a mantra being repeated in Aether's thoughts that he didn't even realize the oni's hands were groping his chest until his nipples were pinched hard.
"AH! T-that's c-cheating…!" Aether cried. "S-stop touching me the–re! ♡♡"
Itto only chuckled at him and kept on playing with his nipples as if he didn't hear anything. Aether felt electricity shooting down his spine with each rough pinch and flick on his nubs, adding up to the almost overflowing pool of arousal deep within his groin. No… this isn't good…! He had to do something or he'd really lose. The blonde head lolled down, unable to bear the sensations overwhelming him but it was when he did that a sliver of hope came back to him. He saw Itto's member poking out from his thighs, oozing so much precum it looked like he was close too.
In an attempt to retaliate, Aether squeezed his thighs harder and took the protruding length in his hand. The oni emitted a deep groan when Aether pumped his hand with a clumsy rhythm, finding it difficult to do so when the girth was so thick he couldn't circle his fingers around it. He toyed with the weeping tip and thumbed at the slit each time it poked out of his thighs. Inwardly, he prayed that Itto would cum soon because he could feel himself teetering closer to the edge whenever the head bumped against his clit.
"c-can't… I can't— no more…! aah no no…! ♡♡"
His pussy twitched from the extra stimulation whenever the tip of Itto's cock kissed his pearl. Despite his hazy mind, Aether registered the sound of Itto's chuckle and what followed next spelled his imminent defeat — The oni angled his thrusts higher, grinding his shaft against the thick folds and kept on hitting the cute nub of flesh. Aether's whole body tensed as he came with a loud whimper, squirt gushing out of him and flowing into the water.
"I hate you… I hate you…" he cried. His body went limp but Itto's arms caught him before he fell face down.
"Haha! You can complain about that later!" Itto boasted, letting him go to sit down beside him and stroke his still hard cock with one hand and tap his leg with the other. His eyes stared ravenously at Aether's naked and sweaty form, his desire palpable through the small space between them. "Come on, ride me."
Aether let out a small whine before he complied and straddled Itto's lap. The heat of their surroundings and his arousal was getting to him, making him feel so dizzy that he had to clutch Itto's shoulders to prop himself up.
"D-do we really have to do this...?" The blonde looked straight into Itto's eyes, hoping for an extremely slim chance that he would be spared today. However, the only response he got was a smirk and a pair of large hands firmly gripping his waist, urging him to take in the cock standing under his dripping pussy. "A-ah! Wait!"
How would that thing even fit inside him? Aether had no idea how to but he could sense Itto's growing impatience. Black nails buried themselves into his waist, threatening to force him down and he whined in protest. If they were going to do this, Aether wanted to have some form of control at least. He gulped a large amount of air as he looked down and teared up a little bit more.
'Okay… okay, I can do this.', he assured himself, spreading his labia with one hand's middle and index fingers and the other hand he used to guide Itto's cock in front of his hole. He shuddered and jerked when the tip kissed his entrance, narrow from the lack of preparation which added up to his fears. It would hurt. For sure . Aether slicked up the shaft with the precum gathering at the tip and his own juices before trying again. The blonde lowered his hips, wincing in pain as the thick head slowly penetrated his pussy. When it finally popped in, his eyes turned white as it rolled back to their sockets and Itto hissed at the tight heat squeezing his cock.
"O-oh… oohhh… i-it's in…" he mewled, taking his hand off his cunt and grasping the oni's shoulders for support. "F-fuck… it—aah… it hurts…"
"You're just too tight! As expected from Inazuma's savior." Itto spoke, voice thick with lust. "even your pussy is unmatched…!"
"D-don't say th—"
Itto pressed their lips together, effectively shutting Aether up from any more complaints. Even if he tried to push the oni away, he just wouldn't budge so Aether accepted it, parting his lips when he felt Itto's fangs lightly biting his lower lip for access inside his mouth. The slitted tongue roughly invaded the cavern of his mouth, swiping across his teeth and tangling with his own. The kiss made up for a good distraction and Aether took advantage of it to sink his hips further, taking more of the cock in.
The spikes caught on the rim of his pussy hole making him mewl into the kiss which the oni welcomely swallowed. Itto's hands went down to his ass, groping the soft mounds of flesh then slowly pressing him down. He would have been grateful for the assistance, until the cock bumped on something and he felt a sting deep inside him, so painful that he had to abruptly pull away to speak.
"Wait—!" He huffed. Aether's gaze trailed down to his own stomach where a small dent was formed where Itto's cock reached, and lower down where he saw that only half of it was in. "N-no… this can't be…" he thought out loud. Itto's hands returned to his waist and he tried to push Aether down again, making his arms flail in panic. "I-Itto! This is–nngh! g-good enough, isn't it…? I f-feel so full a-already..."
Desperate to make the oni agree, Aether slowly bounced himself on the cock, tiny moans escaping his mouth from the sensations wracking his whole body. What was painful earlier soon became so pleasurable that he rolled his hips faster, eager to feel the spikes on Itto's cock drag his insides with each thrust. Sweat made his torso glisten, dyed by a pretty shade of pink.
"Mmnh…! ♡ haaah! ♡ aaah…! ♡♡"
Itto licked his own lips and watched as the plump and blushing petals of Aether's cunt spreaded around his girth as he fucked himself on it. However, being just halfway in wasn't enough, apparently. The oni tried pushing him down again and his eyes widened in fear while he shook his head, feeling that painful sting shoot up his spine.
"I-Itto! What— n-no!! You can't…!" Aether cried. The grip on his waist became even tighter, making his panic shoot up.
"Why not? I have to conquer all parts of you." The oni growled. The tip of his cock felt like it was hitting something firm . "And that means making you take all of it in so you can feel just how good my cock is."
"Y-you can't! Itto…! That's my…" The blonde furiously clawed at his hands in an attempt to break himself free. "My womb… you have to sto— HIIIIIIIIII! ♡♡"
A scream was ripped off Aether's throat when Itto slammed his hips down his cock, piercing past the tight cervix and fully sheathing himself inside the small pussy. His back arched from the searing pain of having his womb torn open and he was left gasping for air like a fish out of water, nails digging into the oni's shoulders so hard that it bled. Aether couldn't form a single coherent word and it felt like he was about to pass out. His insides worked and contracted hard to push out the large intrusion but that only made Itto groan in titillation.
The oni uttered something Aether couldn't understand with his blurry mind so he simply nodded in response, which turned out to be another great mistake. Seconds later, Itto began fucking him out of his wits, easily lifting him up and dropping him down on his huge dick at a steady and quick pace. Soon enough, the pain from having his womb repeatedly battered was dulled into something that made his toes curl. His hole was stretched to its limits but it eagerly sucked in the cock violating his insides.
"Aaah! ♡ oooh—! ♡ s-sho good…! haaaah…! ♡♡"
Aether's tongue dangled out of his mouth as he moaned like a shameless whore, too lost to bother that anyone else might hear them fucking in the open. Itto groaned and purred in tandem with the noises that escaped Aether's lips as he plunged his dick into the tight and searing heat. Like a beast, the oni's deep and resounding growls shook Aether's core and shot straight down to his pussy, making him tighten even more. His heart palpitated and his chest heaved hard, the only thing he could feel now was the barbed shaft dragging along the meat of his tender cunt, rubbing on his sweet spots and making him leak more juices.
"Ittooooo—! ♡ mmmh…! aha—! m-more! ♡"
"Wow, you've turned into such a slut!" Itto chuckled deep. He slowed down his thrusts to grind his tip into the small womb, causing the walls to flutter around him harder.
"ye-yesh…! Nnngh! ♡♡ please, please…! ♡♡♡"
Broken moans and chants filled with "please" and "harder" were sung by Aether who's reduced into nothing but a wanton cockslut. His nether lips have turned red and swollen from the constant smacking of their lower bodies. Coarse tufts of white pubes tickled his clit upon contact shooting sparks of electricity up his spine, frying his brain even more. It was something he could get addicted to, as much as he hated to admit. The slick that came out of his pussy mixed into the water. They would be punished for sullying the place but they couldn't care less, fucking each other even harder until Aether felt another orgasm coming up.
"W-wait…! ♡ aaah! Itto…! mmmh! ♡♡"
Just how was Itto still fucking him energetically? Aether didn't know and he didn't care. All he wanted in that moment was to have that thick cock pound him hard until he reached his peak. He pressed the bulge Itto made on his thin stomach, feeling it move up and down while he was being fucked. His pretty and innocent looking face sported a lewd expression while he caressed the large bump. That, and the sight of the hero's swollen pussy swallowing his girth turned on the oni so much that more of his blood rushed to his cock and it grew even bigger without any warning, stretching the tiny little entrance even more.
It was the last push the blonde needed. He bit into Itto's shoulders as he came, hard enough to make him bleed. His squirt rushed out of his cunt, into the water where it dissolved. His orgasm hit him so hard and made him numb for a few moments, until it wore off and only then did he realize that Itto was still ramming his cock into his hole like a wild animal in heat.
"ITTO…!? S-STOP!" Aether cried, scrambling to get away from the bruising grip on his waist "N-NO…! NO NO— I'LL BR–EAK! YOU'LL BREAK MEEE…!"
Itto emitted a deep and guttural growl that made him freeze out of fear. There was a feral glint on his red pupils as he speared the blonde's sore pussy with his cock, thrusting erratically to chase his own high. Aether fell limp and accepted everything that Itto gave with a sob, crying broken moans as the oni brutally churned his insides and fucked into his womb. He drifted in and out of consciousness, momentarily passing out from the pain and waking up from the scalp tingling pleasure he felt whenever the spikes brushed along his sensitive spots.
With a loud groan, Itto slammed his hips down for the last time and his cock twitched wildly before he shot loads and loads of hot cum, filling Aether's thirsty womb with so much it felt like he was pissing in his cunt. The rush of hot fluids inside Aether inflated his slender belly and made him cum again before completely blacking out with a look of pure fucked-out bliss and rapture on his face.
"It hurts, you stupid oni…" Aether flailed his leg and landed a weak kick on one side of Itto's body.
A hearty laugh erupted out of Itto as he walked down the streets of Inazuma city, carrying the traveler on a piggyback ride. Instead of wrapping his arms around Itto's shoulders, Aether held onto his horns like they were a pair of handles made for that specific purpose. A sour pout was on his face. After that affair, he couldn't feel his lower body and his groin hurt so much he couldn't walk.
"Sorry, sorry! It just felt so good! You have the best pussy in Teyvat, I'll give you that!" Itto chuckled, earning him another kick. "So anyway, we're banned from that place!"
"H-huh!? How…?" Aether had the gall to ask, then he suddenly remembered just how loud they were that he blushed out of shame. "It's all your fault…"
Itto cackled again and after that was silence from the two of them. Aether nuzzled into Itto's neck and took a deep sniff of his hair. Admittedly, it smelled comforting that he was able to calm himself down a little. Staring down at Itto's shoulders, he was reminded of the hard bite he gave there as he orgasmed earlier. His cheeks turned hot and he became even more flushed.
"We should do that again sometime…" he weakly mumbled.
"Hn? Do what?" Itto responded, slowing down his pace. "Go to the onsen?"
"s-sex…" Aether spoke weakly. Itto had to stop in his tracks just to make sure he heard things right. "don't make me say it twice… it's embarrassing…"
Itto laughed again upon hearing his words. "You're on! I'll beat my record and make you cum more than twice next ti—"
"Aaah stop, stop!" The blonde frantically covered his mouth. "Don't say that out loud!!!" His hands muffled the sound of Itto's chuckle. After that, Itto tilted his head towards him, slowly and sensually licking his palm with lust-filled eyes.
Fuck, Aether thought, feeling his insides churn once again. That "next time" might come sooner than expected.
