Summary: An arranged marriage orchestrated by his late mother years before her death leads Jin to Yakushima where a young girl bearing their family name waits for him. (Jin x Asuka)

Warnings: Underage (Asuka is 14, Jin is 24)

A decade had passed since his mother's death and yet her presence still lingered both within his soul and the air he breathes. He could feel her essence course through his veins as it suppressed his devil, and yet the beast stirred, grumbling and writhing as heavenly tendrils wriggled against its mass. Time was of the essence to mend the chains that held down his demon, so he must follow his mother's advice, the letter sent by a prospective maiden that found its way into his mailbox one morning. Written in black ink was his mother's handwriting, urging him to return to Yakushima where an intended maiden waited for him. Jin at first couldn't believe that such a memento of his mother existed, but the scent of the letter and the pulse of his soul told Jin this was indeed Jun's work. She boasted that the maiden possessed spiritual power beyond what Jun could realistically wield, a priestess of natural talent that could suppress his devil completely. Jun took great care to maintain a seal on his heart even in her death, but the chains on his soul grew weaker as time passed. He needed a new seal, and whether he liked it or not, he had to obey his mother's letter despite the lurid undertones it held.

He had to wed her and then consummate the marriage if he wanted her seal to replace Jun's, an act that would bond the girl to him for life as well as vice versa. Only in death would their spirits be free, a fate Jin had accepted if it meant not harboring a demon. Of course, he had his concerns, but Jun promised him a vivacious maiden befitting his tastes; a beautiful girl of only fourteen springs named Asuka. She was a Kazama birthed by an unknown uncle's wife, fated to be his companion through an arrangement of marriage. To be so young and to have such responsibility pained Jin somewhat. She had a whole life ahead of her and yet she intended to dedicate it to him, a cousin she had never met or known. Jin found the concept strange and he wondered if she thought the same as well.

Once Jin entered the forest, body enveloped by twisting vines and warm mist, he walked through a vernal pool that led to a clearing, dominated by a giant cedar tree. From there he saw a girl carrying bucket pails filled to the brim with bright red berries she carried in her gloved hands. Jin gathered his thoughts and slowly approached her, intending to greet her first, but she beat him to the punch.

"Welcome, welcome," She smiled and quickly approached him, arms swaying as she moved bare feet through clear waters. "Are you Jin?"

"Y-Yes..." Jin nodded, hand gripping his carrier bag. "Are you Asuka...?"

"That's my name, don't wear it out!" She giggled and put down her pails to shake Jin's hand in her smaller ones. "Welcome to the neighborhood, aniki. It ain't much, but I like to call it home. Baachan told me great things about you!"

"...Have you met my mother before?"

"Mhm, when I was little, but we were still really close." She explained and then let go of his hands to cross her arms. "You probably didn't expect that letter though, huh?"

"No, I didn't." Jin shook his head. "I assume you'd know what my mother meant by this arrangement, correct?"

"Naturally," She shrugged a little. "But here, I'm sure you've been standing around all day," She grabbed her pails and walked ahead of him. "Come on, I'll show you where the hut is."

Jin followed, but remained silent for now, opting to observe this strange girl rather than distract himself with idle prattle.

"Your mom wrote that letter ten years ago before everything happened. She knew the ogre would kill our clan and gave what she wrote to my dad." She began. Jin cringed at the thought. "Then dad gave it to me, and once I felt your seal weaken, I sent it your way. Baachan's orders."

"But why?" He asked. "What sort of power do you possess that would help me?"

"The same that she had, just more of it. Nothing really special. I can make you a new seal, but bonding our souls is what will make it permanent."

"So what she said was true then..."

"About what?"

"Marriage..."

"Ah, that... Yeah, it's true, but it's a really quick ceremony if it helps you feel better. I just place a hand on your heart, recite a few words, and poof! Married!" Asuka laughed but then got somewhat serious. "But it's okay if you're not ready yet... The seal you have now is very weak, but I reckon it won't break for another few months. You'll have time to get used to things around here till then."

"You are...comfortable with this?"

"I've been waiting for this for a long time. It's a duty I'm more than happy to fulfill if it means I get to help you, aniki." She looked over her shoulder to smile at him. "You don't gotta worry about me, I'm not bothered by it at all! I think we'd make a pretty cute couple~!"

Jin ignored that last comment and decided not to press her on it. She was certainly precocious for her age.

Although, he can't help but question if his mother was right for doing this to her.

The pair eventually trekked down a cobbled path that led to Asuka's home, a humble minka swallowed by trees and groves. The sight of such a thing filled Jin with a sense of nostalgia that grew deeper when they went inside, the interior design reminding him of his childhood home.

"Sorry, sorry..." He moved out of the way when Asuka trudged past him to enter a room with her pails of fruit. "You can throw your stuff wherever you want. I'll take you to your room in a minute."

"Thank you." Jin placed his stuff on the floor and then followed where Asuka went. She was putting her berries away in a small refrigerator. "You're here by yourself?"

"Yeah. I had my papa with me at one point, but I made him go back home. I got too old for it." She ate a berry and guided Jin to the living room. "After a while you get used to doing things by yourself."

"I'll try to stay out of your way then."

"Haha! Don't worry, you won't bother me!" She patted his back. "You'll be here for a hot minute, so just make yourself at home, aniki."

Jin grabbed his things and let Asuka lead him to his room where a thick tatami mat and a desk waited for him. For that first night, Jin spent most of it by himself, quietly making peace with the situation. Asuka was young, but his mother's wisdom made her wise, if not a little rough around the edges. Perhaps spending most of her life dedicating herself to his safety in isolation made her a little rowdy. He couldn't blame her though; the poor thing never had much company it seemed.

Beyond taking food and drink, and assisting with the occasional house chore, Jin didn't interact with Asuka for the first week and busied himself with training. He wanted to stay out of her way, but Asuka always found a reason to stick by him to give him food or educate him about their clan. She took great pride in their family heritage and did what she could to uphold the teachings of their ancestors. She trained her soul, practiced Kazama-style martial arts, and took on duties specific to her gender like her ancestors before her. She knew how to defend herself, but also liked to cook, clean, and manage the home, qualities he thought were pleasant for a woman to have. Jin never had a preference for what kind of mate he'd like, but a self-reliant woman was a trait he appreciated in a wife.

When Jin was done training for the day, he'd eat dinner with Asuka which was usually a meal consisting of a meat dish, soup, rice, and a veggie of her choosing. He liked her food a lot and often received second helpings when she noticed that he had cleaned his plate.

"Here ya go, aniki," She'd kneel beside him to clear the table before pouring him a cup of tea and placing more food in front of him. She was small, at least compared to him; she only reached his shoulders when she sat next to him.

"Thank you." He'd say. "You're a very good cook."

"Oh, do you think so!?" She looked pleased with herself and cupped her plump cheeks. "Uwah, that makes me happy! Aniki can have as much as he likes!"

Asuka was always playful and lackadaisical despite her maturity, but her girlhood shined through like a shooting star when Jin complimented her cooking. He at first had reservations about her age, but Jin found himself entertaining the idea of marriage the more he spent time with her. He was already 24; perhaps spending his days with a younger girl would be best for him, especially if she could give him children one day.

Jin became more conscious of Asuka as days turned to weeks. He trained with her, told her about his experiences with the devil and the man he inherited it from, and bonded with her through play and house chores. He took to her way of life like a duck to water and it reflected in his habits. He caught his own food, wore traditional cotton gii and kimonos, and spent much of his time with nature. Asuka was always a step behind or ahead of him of course, a little shadow that he found comfort in. He could already feel her very presence influence his soul, an essence that lulled his beast into a slumber when he felt it pull against its shackles. She had great potential as both a wife and protector; he wondered if she felt the same about him, but judging by Asuka's wayward gazes and precocious comments, there was evidence that she too had a keen interest in their union.

They were more than privy to the circumstances that brought them together and knew that such a fate meant more intimate contact eventually. Asuka liked to touch and caress, little touches along his chest and biceps she'd leave when she was being friendly with him, but Jin didn't do much to reciprocate as he wasn't a very physical person. Asuka was aware of this and tempted him with sly words and lurid comments, especially when they bathed together. She liked taking him to a nearby onsen after a hard day of labor, a hidden retreat that Jun and her father had shown her many years ago. Jin preferred to sit in the water and meditate while Asuka basked in the steam with a can of cold tea. Tonight would be no different, but Asuka felt emboldened enough to ask Jin a question he didn't know how to answer.

"Niichan~" She began, legs kicking in the water. Niichan was what she preferred to call him when she was feeling playful. "Can I ask you something?"

"Sure," Jin was standing next to her, ready to slide into the pool, but decided to take the time to entertain her. "What's up?"

"Can I see your thing?"

"My thing...?" Jin repeated. "What are you talking about?"

"You know your thing," She motioned towards the short towel wrapped around his waist. "I wanna see it!"

"W-What?" Jin reflexively gripped his towel. "Why now all of a sudden?"

"Well, I'm gonna see it eventually, aren't I? I wanna know what I'm working with." She kicked her legs faster. "Besides, I've never seen one up close before!"

"Asuka..."

"C'mon, please?" She batted her eyes. "Just once and I won't bug you again about it..."

Jin sighed and then glared at his cousin. He wasn't a shy man, had plunged enough women in his life to not be, but he thought Asuka would appreciate a longer courtship than whatever this was. Regardless of his feelings though, she did have a point; she was going to see "it" eventually. No point beating around the bush anymore.

"Alright, alright..." Jin grimaced as he slowly untied the towel obscuring his privates. "You're being a real brat today."

Asuka turned to face him completely, now kneeling over wet stones to watch him free his cock. Her eyes are wide and expectant once the towel falls off Jin's hips, damp cotton clinging to the fat trunk of his shaft before crumpling to the ground in a heap, revealing a dark, thick cock tucked within a dense nest of curling hairs. Jin awkwardly rubbed the back of his head as his flaccid member swung between his thighs, knocking against scarred knees like a pendulum in a clock case, before taking a step towards his cousin who looked both amazed and stupefied by the sight of his organ.

"W-Woah..." She cocked her head to the side, eyes shining with hidden mirth. "Aniki, you're..."

"Don't stare so hard," Jin admonished. "Out of all the things mother taught you, wasn't modesty one of them?"

"Must a wife be such a prude around her husband?" Asuka countered. "You're so old-fashioned, niichan~" She reached for the crown end of his organ before suddenly pulling away. "Is it okay if I...?"

Jin considered it and then gave her his answer.

"Go ahead."

"It's so big and hard, like a dragon..." She caressed him with her fingertips and stroked it carefully, turgid meat bracing the length of her hand as its tip rested against her wrist. "I can't believe this is going inside me..."

Suddenly, a twitch, his cock lurching a little at Asuka's words and touch. Yes, he told himself; this will go in her, no doubt before the end of the Summer. He'll pop her cherry, plunder her womb, and make her a wife, just like Jun planned for him. It's a thought that is taboo as it is alluring.

"And this... Oh my," Her hand travels under his cock to cup his loins, a dangling pair of heavy balls that hang low between his legs. She gently squeezed them before rolling them around in her palm. "How do you walk around like this, niichan?"

"I just do..." Jin huffed through his nose.

"Aniki must've had a lot of girlfriends." She used two hands now, one that kneaded his balls while the other fondled his shaft. "Did it hurt for them?"

"Some of them..." Jin flinched as he recalled a brief romance with a high school friend, a Chinese expat he still maintained contact with. She was a virgin when they fucked and he had to be very careful with her. "But I was always gentle. I never gave them too much they couldn't handle."

Jin noticed Asuka rubbing her thighs together. It sent a shiver down his spine.

"I'll make it feel good." He blurted out as if it were the most natural thing in the world.

"How would you do that?"

"I'd kiss you, lick you..." His cock jolted upwards. "Until you're wet enough for me..."

"Wow..." In awe of his promise, she prodded his slit a little with a short nail, and then took her hands off of him. Jin shuddered in place, cock now at half-mast.

"I really like this," Asuka laid back on the ground and played with the towel wrapped over her chest and stomach. "Would aniki like to see mine?" Her legs were already spreading apart in anticipation, parting thighs giving Jin the briefest glimpse of an unshaven cunt.

What was he supposed to say? No?

"Yeah," He swallowed thickly as he lowered himself to her height. "I would."

Asuka grinned mischievously, red face growing redder with excitement as she peeled away the towel covering her body. Endowed like a grown woman, Asuka's breasts are big and weighty with dusty nipples and dimpled areolae that blend into her skin. They hang off her chest like overripe fruit, less perky than what he's used to seeing, but still magnificent to behold. Jin licked his lips and crawled to Asuka's left to see her body up close, eyes dancing along a toned belly and flaring hips. Asuka spread her legs wider then, eager to show off.

"You like?" She looked at him expectantly.

"Yes..." Jin watched her expression as he laid a hand on her thigh. She flinched but didn't move away. "You're a big girl."

"Hee hee, I got them from my mom!"

"Very pretty..." He smoothed his hand over her skin and up her belly, eyes trained on her big tits. "May I?"

"Mhmm..." Asuka laid back. "It's only fair."

Jin did the same and laid on his side, sliding his hand upwards to cup a swelling breast. It was soft and supple, and yet dense like warm dough. His cock was hard and aching when he squeezed and shook it, a gentle bounce that Asuka moaned at it. He watched her face again and smirked at the furrow in her brow when he pinched her nipple.

"Do you like that?" He asked. "Do you like it when I play with them?"

"Uh-huh..." She nodded. "Feels good..."

"Wanna do more?"

"Yeah," Another nod. "You can do whatever you want, I don't care."

"Eager little thing..." Jin rolled towards Asuka to kneel over her body, cock dangling menacingly over her fuzzy pubis. It was so very tempting to ravish her right there, but Jin had to wait; she was a virgin and he'd love to know her more intimately before doing anything hasty.

His nose brushed over wet, lilac scented skin as Jin made his descent to her right breast, mouth watering when he sucked her teat into his mouth, slick tongue sliding over a softened nipple that quickly hardened in his mouth when he held it between his teeth.

"A-Aniki..." Asuka held a hand to her mouth. "Ooh, don't stop, please..."

Jin nibbled on her teat in response, teeth worrying marks and chewing bruises on her skin. He had no plans to stop, not when her tits were as big as they were. He was fine with sucking, licking, and chewing on these beautiful breasts for the rest of the night, but knew there were parts of Asuka that needed his attention, like the bushy little cunt that laid between her legs.

Jin gave Asuka's breast one last lick of reverence before setting his sights down below, maintaining eye contact with her as he kissed a path down her navel. He was eager to sample her quim, wanted nothing more than to taste her pussy and fill her with his tongue, but Asuka's little voice stopped him in his tracks.

"I wanna kiss you down there, too," She declared.

Jin would be a fool to deny her.

"Sure, why not," Jin rolled off of her again to lay down on his back. "Come sit on niichan's face."

Asuka smiled like a little whore, teeth biting into candy pink lips as she obeyed her cousin's command. Jin watched her ass as she climbed over him, entranced by shapely buttocks that further enhanced her womanliness. She then parted her legs once she's on top of him before laying across his body to touch his cock again, a move that naturally spreads her pussy apart for him. Her virginal hole is slick with need, dripping with honeyed arousal that falls over fuzzy lips and a plump clit. Jin is too seduced by Asuka's cunt to not indulge in it and quickly sated his lust for his baby cousin by dragging his tongue over her entrance. Asuka squealed and thrust down into Jin's mouth reflexively.

"Aniki..."

Jin hummed, tongue too busy worshiping her pussy to give her a proper response. He rolled it up and over her hole, flicking incessantly at a throbbing maidenhead as he smoothed his hands over her rear end. Asuka melted like butter then, unable to do much to his cock except stroke and caress it, maybe kiss it a little when she focused hard enough. He honestly can't help himself; he loved eating out good pussy, especially a wild one like Asuka's. She was all natural like a woman should be.

Jin puckered his lips to suck along her slit, curling tongue smothering her throbbing clitoris in spit and sweat. Her juices rolled over and mingled with the mist on his skin while the squelch of his mouth made his cock pulse. Asuka's moans were now breathless mewls, pleasured squeaks and squeals that vibrate along his prick when she tried putting him in his mouth. Her efforts are short-lived, however, as she's too wound up by Jin's tongue to do much else besides whimper and gasp.

"Niichan, niichan, niichan...!" She called his name, hips moving in time with his mouth. "I can't hold it...!"

Asuka's cunt trembled and shook when she reached her limit, a sensation that forced a carnal growl from Jin's throat. More slick coated his tongue then, a delicious flavor he savored by swallowing it whole, filling his nose and throat with a taste he likened to rosewater. His cousin panted and writhed like the sweet virgin she was during it all, limply grasping at a cock too big for her as she rode the waves of her orgasm. Little slut, he wanted to say; got too big for her britches.

A soft laugh left Jin as he pulled himself away from Asuka's quim, tongue greedily lapping up strings of spit and his cousin's arousal when he laid his head on the ground. Asuka meanwhile stayed down, unable to move anything besides her head.

Jin gave her an encouraging pat on her left cheek. "Asuka..." He called for her. "Are you alright?"

"Uh..." She lifted her head. "Uh-huh..."

"Would you like a break?" He idly prodded her hole with a thumb. "Or do you want to go again?"

Jin is too hungry for his cousin to consider stopping but knew better than to push her to places she wasn't ready to go to. Luckily for him, Asuka was a tough cookie and propped herself on wobbling arms to finally service him.

"You didn't finish yet..." She whined.

"Here, let me help you out," Jin patted her thigh. "Turn to me, Asu."

Asuka obeyed, eyes filled with wonder when she looked past her cousin's cock to stare at his face, patiently waiting for his next command.

"Good girl," He petted her hair and then gripped himself, fist circled around the lower half of his prick to keep her from sucking it too deep. "Get it nice and wet for me, like I did to you."

Asuka stuck out her tongue and swiped at his glans at first, treating it like a lollipop. She smacked her lips at the taste of his precome and then sucked the head into her mouth, little tongue peeking between spit-slicked lips to swirl it around bulbous flesh and peeled foreskin. Jin grunted, had the instinct to thrust into her mouth, but smothered the urge for her sake. Instead, he laid back and watched her work his cock, eyes half-lidded and foggy with barely contained lust.

"Mmm, that's it, Asu..." Jin reached down to cup her cheek. "Keep it up..." A firm suck had him moaning. "Fuck..."

Asuka watched his expressions intently, sucking harder and licking faster when she saw his face contort. A fast learner with womanly intuition, Asuka took him deeper, as deep as she could go anyway. His hand kept her at bay, prevented her from choking on herself, and she seemed content with that. He was used to women swallowing him whole and savoring every inch of him, but Jin was fine with Asuka's gentler approach. She will get used to it with time; no point rushing something he'll reap the benefits of later.

A gentle squeeze of his loins by her hand takes Jin out of his thoughts, pit of his stomach suddenly coiling with need. He didn't realize he was so close; all the touching, kissing, and groping must have done a number on him.

"Asu..." Jin hissed, Asuka's mouth now moving faster. "Good girl, love, don't stop..."

Asuka closed her eyes, focused on making him come. Her tongue curled along his shaft and rubbed bulging veins, cockhead now prodding the front of her throat. She coughed a little but kept at it, spit and dribbling pre clinging to her cheeks like thin glue. Jin dug his nails into the ground then, the coil in his gut growing tighter and tighter until it finally happened. He expected Asuka to pull away, but she remained where she was, drinking up his hot load like it was precious soma.

"Mmm..." She swallowed what remained in her mouth as she slowly slid off his wilting member. "Weird taste, but I'll get used to it."

"For a maiden you sure don't act like it." Jin quipped. "Had fun though?"

"Mhmm! Lots!" She crawled over him to settle herself on his chest. "Who knew my big cousin was such a stud muffin~"

"Where did you learn to talk like that?"

"I'm not a bumpkin, ya know. I read a lot of books when I can." She gave him a sly grin. "Does this mean we can get married now?"

"Relax, we will." He cupped her buttocks. "I swear, leaving you alone on this island made you a horny little thing..."

"Your mind starts wandering when you're bored..." She then snuggled into his chest and sighed happily. "But aniki's here now, so I don't have to be bored all the time!"

Jin shook his head but smiled anyway. He had his opinions about Asuka and their combined fates, but it would appear he trapped himself in his head. Jun was wise to leave a wife as passionate as Asuka for him. He was fully prepared to fulfill his duties as her husband even after she expelled the devil from his heart. She was simply too precious to let go, a white star in a black void he could hold onto for the rest of his days.

Perhaps it was time to get married...
