Stuck on an Island with a Cute Demon

By Yangster

Chapter #8: A Heated Moment

Exploring the island had yielded lots of rewards.

From that single bunker they had discovered came a whole underground system of tunnels leading to all sorts of different places on the island. They had uncovered all sorts of things such as crates containing random bits and bobs, several more cases of spoiled sake, and weird metal contraptions that looked like tubes with switches on them. Those were actually not that interesting. The reason why being they had no idea what to make of all of it. Plus, they had almost completely forgotten about all that stuff when they found the best thing on the island thus far.

It was a natural hot spring.

A natural hot spring surrounded by delectable fruit trees and close to a beautiful clearing large enough for them to make another shelter in. Not only that, but it was also close enough to the river that they could enjoy their water hot or cold as they pleased. It was as if heaven had opened up to them and welcomed them inside after all the gross tunnels they had to crawl through. Discovering that gloriously steamy spring had made the entire trip worth it—which it already was since they got to spend time together.

They wanted to savour this discovery—it was that great. So, for the first few days, they did not dare step into it or even dip a toe into its healing waters. It had been Kyuumiko's decision to wait a while before using the hot spring because she knew that the moment they stepped in, they were going to end up instantly addicted to the feeling of hot water after all those weeks without on the island. Naruto had protested at first, but a few soft kisses and sweet looks had him swayed very easily. She had that power over him after-all.

Now that those few days were up though, they could finally enjoy themselves in the hot spring.

"Ooooh," let out Naruto, shuddering as he slowly lowered himself into the blissfully hot waters of the spring.

Kyuumiko let out a soft and amused snort as she watched him—she had let him go in first. "It feels that good, huh?"

"It does," he said with a sigh, sliding himself further down so that he could rest his shoulders and the back of his head against the smooth rocks that were around the hot spring. "It is as if I'm melting..."

"It can't really be that goo—!" Kyuumiko let out a moan the moment she dipped a toe in.

"See?! It's that good!"

She blushed as she slowly sank herself down into the water.

"It... It really does..." She trailed off slowly, lingering ever so slightly on the last syllable of what she had said as she was overcome with bliss. "Mmm..."

"And I thought I was being dramatic," he commented, letting out a quiet chuckle as he slowly made his way over to her.

"It has been almost a century since I have experienced the pleasure of a hot spring, Naruto," she said softly, letting out a soft sigh akin to his from earlier.

Naruto hummed in response. "Hmm. I guess that might make it more intense for you."

"You know, Naruto..." began Kyuumiko, her nervous tone causing Naruto to quirk a brow. "Maybe the reason why it is so intense for me when you... Maybe it is because I am several thousands of years old and you are the first person to ever touch me like that..."

"Is that a bad thing?" he asked.

She quickly shook her head. "N-No. Not at all, Naruto."

"Well..." Naruto trailed off as he took a breath. "It was really intense for me when you first used your hand. I hadn't really touched myself since we came onto this island because... Well..."

"Because at first I gave you no privacy... And now because you have me to do it for you?" she asked, offering him a gentle smile as she slowly waded over to where he was sitting.

"Yeah..." His cheeks were flushed as he smiled back at her.

She hummed a sweet, song-like, note in response as she sat herself right next to him. Wrapping her arms around one of his, she purposefully pressed her large, plump, and bountiful breasts against him as she rested her head against his shoulder. He reacted in turn by caressing her cheek and tucking some stray locks of her silky orange hair back with his free hand. The sensation of his fingers brushing past one of her ears elicited a quiet purr from her, which encouraged him to go a bit further and give her some delightful ear scratches, causing her eyes to roll back and for her to start moaning.

"N-Naruto..." Kyuumiko trailed off before letting out another moan when he turned his head and began nibbling on her other ear. "Wow... That's new..."

"Your ears are always so sensitive," he commented in-between nibbles.

Kyuumiko nodded slowly. "They... They are..."

"Are you the most sensitive there?" he asked, whispering those words into her ear before he resumed nibbling on them.

"A-Ah! I... I don't know, Naruto. I don't know which part of me is the most sensitive..."

He licked his lips.

"Do you want to find out?"

Those words had come out so unexpectedly husky that she had actually shuddered when she heard him whisper them into her ear. She could feel the heat that she had become familiar with after all those wonderfully intimate moments that she had shared with him quickly building up inside of her in that spot just below her navel—she knew it now to be her womb—and her cheeks too as she blushed. With the steam from the spring rising up before them, she could not tell whether this slight haze was from it or the budding arousal that was quickly overtaking her.

"I do..." she answered, her blush deepening when he slowly slid his hand down from her ear to caress and then cup her cheek. "You've gotten a lot smoother, Naruto..."

The corner of his lips curved upwards to form a proud smirk. "I have."

"I think it's time that I caught up," she said, returning the smirk as she moved to straddle his hips, her sudden boldness causing him to widen his eyes in surprise. "Don't you think, Naruto?"

Her smirk faltered for a moment when she felt how stiff he had gotten when he was sweet talking her. He was so incredibly hard that it took nearly every ounce of her willpower not to shudder again. Just feeling his large, hot, and manly cock that close to her special place made her loins burn with want—no, need. Kyuumiko held herself there for a few seconds as she calmed herself. Then, without warning, she clasped her hands behind his neck and slowly slid herself down, pressing her bountiful breasts against his sturdy chest as she did so. Her efforts were rewarded when Naruto let out a soft groan as he felt the top of his member slide up against that tight and smooth space between the fat globes of her plump and perky ass.

He could feel his cheeks flush—it was now his turn to blush.

"I have a feeling that it doesn't really matter what I think at the moment, Kyuumi," he eventually said.

She grinned foxily at him. "You have as much power over me as I do over you, Naruto. Though it seems that I've sapped you of all of it at the moment."

"It does..." He placed his hands down onto her hips and gave them both a firm squeeze, causing her to bite down on her bottom lip. "So, how do you want to go about this, Kyuumi?"

"Mm..." She licked her lips sensually before slowly parting them. "I want to try something new..."

Naruto lofted a brow. "Oh?"

"I want to use my mouth..."

His blush deepened.

"Oh."

"Please?" she asked sweetly, canting her head to compliment the innocent, wanting look that she was now giving him as she began to slowly grind her rear against him.

Naruto swallowed quietly, the action doing nothing to help him come up with any words. All he could do was nod, which he did—slowly. Utterly speechless, he let her guide him up onto one of the large, flatter, and smoother stones surrounding the hot spring. Then, he watched as she placed her dainty and delicate hands onto his knees and eased his legs apart before sliding herself between them. He could feel her arousal roll off of her body in waves as she licked her plump lips at the sight of his cock before her, joining with his as she got closer and closer to him.

"I have been dreaming of this for a while now," he confessed, his blush making its return.

She looked up into his eyes before giving him a gentle smile. "Allow me to fulfill your dream then, my dearest."

"Ooh... Dearest. I actually really liked that," said Naruto, returning the smile.

"I have been thinking about what else to call you for a while now," began Kyuumiko as she canted her head to one side and began nuzzling her cheek against his inner-thigh. "Like honey or darling. I ended up liking 'my dearest' the most."

"It's fitting," he replied, letting out a shaky breath as he tried his best not to fidget. "I wouldn't mind if you used all three. They each have their own charm to them."

"They do..." Kyuumiko trailed off as she slowly dipped forward and pressed face against his cock. "Your thing has a charm too, Naruto... It's luring me in, seducing me in its own way, turning me into a lewd girl just for you..."

He let out a shaky breath as he watched her. "God..."

"You're so big, Naruto... Look at how your thing manages to reach all the way to my forehead when I put my chin down on you... And the smell..." She paused as she inhaled—softly at first before she did so again much more deeply. "I could get drunk off of it."

Naruto would not ever dare tell her this, but he thought that she looked the sexiest when she had her face pressed up against his cock. Just the way her eyes would become half-lidded combined with how her cheeks flushed and the hazy smile she had on made him go absolutely crazy. Part of him wanted to just grab her by the sides of her head and force himself into her mouth and down her throat—to feel her choke and gag on him. The part that won over however, demanded that he watch as she praised—essentially worshipped—his cock.

"Kyuumi..." he said huskily, almost impatiently, as he slowly placed one of his hands atop her head.

"Mmm... Sorry for making you wait, Naruto." She offered him another smile before she moved one of her hands and wrapped her dainty fingers around the base of his cock. "All this steam is just going to my head."

Raising herself until her wet, bountiful breasts were out of the water, she then dipped further forward, and pressed a soft kiss to his sensitive head. His thing twitched in response and began to ooze that delicious precum of his that she had grown to love from its tip. Emboldened by this, she gave it a few licks, causing his breathing to quickly hasten as he got more and more aroused. It took every ounce of his strength to not buck his hips when she began to swirl her wet, delicate, and warm tongue on his tip.

"That... Feels really good, Kyuumi," he said breathily as he began running his fingers through her silky, orange hair, tucking it back as he did so, earning him an appreciative moan from her.

Encouraged by his praise, she then took the head of his cock into her mouth. Sealing her plump lips over it, she then began experimenting with her tongue. Naruto could only throw his head back and groan as he felt her begin to put in work with that wonderfully warm tongue of hers. She swirled it around his head, glided it up and down that sensitive spot at the base of it, and teased out more of his precum by simply sucking on it. Wanting more and wanting better from herself, she then began to stroke him with her hands—much to his delight.

"Mm... Your cock is delicious," she murmured after she released his tip from her mouth.

"Is it really?" he asked.

"Well, your precum is." She grinned at him.

Feeling bold, he slowly pressed down on her head. "Please go back to sucking, Kyuumi..."

She let out a giggle.

"Alright, Naruto. Anything for you, my dearest."

Sealing her lips over his sensitive head once again, Kyuumiko then wrapped her fingers from both hands at the base of his cock before she tried taking him as deep as she could. She heard him suck in a breath as she took inch after inch of him into her mouth before pausing when she felt herself about to gag. Closing her eyes, she kept him there, and stroked him with her hands as she waited for her throat to relax. Peeking up at him, she could not help but smile when she saw the pleasured expression on his face.

"W-Wow..." He gasped.

It was easy knowing what to do when she could tell what he liked best by listening to the noises he made. She was quick to figure out that he liked his blowjobs like his handjobs—with one of her hands wrapped around his base. Doing it how he liked, she began to bob her head up and down on his cock, making sure to caress him with her tongue, while keeping it steady with one hand and using her other to fondle and caress his heavy sack. Sucking hard to the point where her cheeks went concave, she felt her chest swell with pride when he let out a groan at the intense increase of suction.

"T-That feels amazing, Kyuumi," stammered Naruto, his breathing shallow and his pulse quick as he tried not to cum.

He was so close now. He could feel everything she was doing to him—even the most subtle of touches from her—from the squeezes she would give to the base of his cock, to that sweet sensation of her plump lips sliding up and down his shaft, and her warm tongue gliding and swirling—worshipping—his sensitive tip. There was a tightness down there that he could have never possibly imagined as his member began to swell inside of her hot, welcoming mouth. She picked up the pace, causing him to bite down on his lip as all those wonderful sensations were intensified.

"I-I'm cumming!"

Kyuumiko hummed appreciatively in response, encouraging him further as he began to buck his hips, forcing himself deeper against her throat. The muscles in his legs and abdomen tensed up and tightened when he finally came. His cock throbbed and he balled some of her hair in his hand as he erupted inside of her mouth. She moaned lewdly as several thick ropes of his hot, potent seed shot onto her tongue, against her throat, and the inside of her cheeks. She sucked him earnestly, swallowing his cum whenever she could, drawing out his orgasm for as long as possible for both him and herself.

Falling back with her still between his legs, he let out a heavy breath followed up by a few soft moans as she continued to bob her head—slower now that he had finally came.

"Kyuumi..."

She slowly pulled herself off of her cock, making sure to keep the suction going all the way until she finally released him. "Mmm... Naruto..."

"God..." he said breathlessly as he raised an arm to cover his eyes. "That was... Too good..."

"I'm glad you enjoyed yourself, my dearest," replied Kyuumiko, climbing up over him, and offering him a gentle smile once they were face to face.

Naruto managed to smile back all the while trying to catch his breath. "You're amazing, Kyuumi."

"That I am," she said, her smile slowly turning into a proud smirk as she placed both of her hands on his broad shoulders "Don't you think that you are even more amazing though, Naruto?"

"How so?" he asked.

"You have the most powerful tailed beast in the world as your lover," began Kyuumiko, grinning foxily at him before she then lowered herself and began nuzzling her cheek against his chest. "And you've made her fall for you in such a way that she has willingly made herself into your lewd, little vixen."

He felt his face heat up as he blushed. "Well... Now that you put it that way, Kyuumi."

"Mmm... I am glad you see it my way now," she said softly, trailing one of her hands down from his shoulder down to one of his toned lateral muscles.

"Hmm..." He hummed softly, closing his eyes as he stretched. "Kyuumi..."

"Yes?"

Naruto moved one arm to wrap around her lower back and reached down with the other to grab firmly onto one of her butt cheeks. "You ready for your turn?"

"Are you going to use your mouth too?" she asked, her cheeks flushing when he gave her plump rear a squeeze.

"Of course," he answered huskily, his gruff sounding voice causing her blush to deepen before he rolled them over so that he was on top and she was beneath him.

Kyuumiko bit down on her bottom lip. "I'm really starting to like that voice you use..."

"Really?"

She nodded her head and offered him a reassuring smile.

"I find it really sexy."

"I'm still nowhere near as sexy as you are, Kyuumi," said Naruto in response, moving one of his hands up to cup her cheek. "I really am the luckiest man in the world."

"Mmm... Definitely... Now are you going to keep talking, Naruto, or are you going to kiss me?" she asked, flashing him a toothsome grin.

Letting out an amused snort, Naruto then slid his other hand underneath her head, and dipped forward. Pressing their lips together, she immediately reciprocated by parting hers just enough to give him the option to use his tongue if he wanted to and by placing both of her hands on his shoulders. Guiding her so that she canted her head to the side, he then took that option, slipping his tongue inside of her mouth, seemingly uncaring of what had just been inside of it just a few minutes ago. It seemed she cared a lot more than he did though because her eyes widened when he did it, though they quickly fluttered back closed as she melted into the kiss.

Kyuumiko was moaning without even knowing it as he continued to kiss her. His lips were so firm, and they seemed so perfectly molded against hers that if this was how they were going to spend the rest of the day, she was fine with it. Though as he slowly parted from it and began to trail those wonderful lips of his down her body, she knew—and was excited at the fact—that they were going to be doing a lot more.

"I... I know that you wanted to find which part of me was the most sensitive, but... Naruto... Dearest... There's only one spot I want you to focus on right now," she said bashfully, her body flushing wherever he kissed as she slowly spread her legs for him. "Please..."

"You're so hot when you act like that," he said, licking his lips as he positioned himself between her legs with his lower-half in the water of the hot spring.

"When I act all submissive for you, my dearest?" she asked, the corners of her lips curving upwards to form a wanting smile on her face as she raised her legs into the air, causing her delicate folds to spread in kind, revealing its soft pink colour to him.

Naruto snaked both of his hands underneath her meaty thighs and gave her a rough tug towards him, causing her to let out a surprised squeak. "Yes."

"Oooh..." she let out, blushing at his boldness.

Sinking himself down into the water, he moved his hands so that they were on her inner-thighs instead. Keeping her legs spread, he dipped forward, and placed his head between them. There was such an enticingly sweet smell that was coming from her that made him want to dive right in, but he wanted to savour her as much as she had savoured him. She was getting aroused just by him looking; her cheeks were flushed, and this clear, thin, and slimy liquid had begun to ooze out from her slit, down her taint and then her asshole—some of it even managed to drip down onto the stone that she was lying on.

"You're that excited, huh?" he asked as he looked up at her.

She nodded her head, her blush deepening as she did so. "Y-Yes..."

It was such an adorably honest reaction that he had blushed also. Letting out a soft chuckle, he pressed his fingers against her inner-thighs, causing them to sink into her plump flesh and for her sex to spread even further, revealing her clit and her tight slit. Swallowing quietly, he then tilted his head forward, and gave her a soft lick from the bottom of her sex all the way to her clit. She moaned softly and moved her hands up to the crook of her knees to hold back her legs as she bent them, giving him even more room to work with.

"A-Ah..." she let out, her eyes glazing over with lust and arousal.

Emboldened by her taste—and by that cute noise she had made—he gave her another lick. Then, moving his hands around her legs to her hips, he then pressed his lips against her sex, and began gliding his tongue up and down her delicate folds. She bit down on her bottom lip and squeezed her eyes shut, the pleasure quickly getting to her. Not seeing somehow made it even hotter for her—having one sense taken away from her made everything he did to her feel even more intense. She was panting now, her breaths coming out hot and laboured as he continued working her with his tongue and lips.

"M-Mmm..."

Kyuumiko let out a moan when he began focusing on her clit. He was gentle with it, caressing it with his lips while using his tongue to swirl around it. She had thought that it was going to be too intense, but he was doing everything so well—it was magical. She could feel it now—the fire—building up inside of her, spreading to every part of her body—her fingers and even her toes—as he eased her closer and closer to her climax. She had thought that she would have lasted longer, but he had found that perfect rhythm so quickly and had stuck to it so well that any second now, her eyes were going to roll back into her head, and she was going to cum.

"N-Naruto! I-I'm cumming!"

There was no holding back now, she thought as she threw her head back. Her legs moved on their own when they tensed up around his head. Squeezing him between her meaty thighs, she began to quiver when her orgasm hit her. A powerful surge went through her as she came—hard—cumulating into her letting out a loud cry of pleasure. Her entire body flushed, her back arched, and her toes curled as she rode out her intense climax. Her lewd honey seeped out her sex, coating the bottom half of his face along with her inner-thighs, marking him with her sweet scent.

"Mm... Dearest..."

Her legs slowly sank back down as her muscles began to relax. Her chest continued to heave, causing her heavy breasts to rise and fall with each breath as she tried to calm herself. She had thought before that experiencing something as wonderful as this would have given her the patience she needed to wait for when they were both ready to go all the way together. All it did was make that fire inside of her burn even hotter. She really was turning into a lewd girl for him.

"It's my turn to say it," he said, the corner of his lips curving upwards. "You taste delicious, Kyuumi."

Kyuumiko's cheeks flushed as she slowly looked up at him. "Do I now?"

"You do," answered Naruto, collecting some of her cum from his chin before licking it off his finger.

Her blush deepened.

"I wonder if it is as hot for you watching me swallow your seed as it was for me just now when you did that..."

He let out an amused snort. "It is."

"God, Naruto..." She trailed off as she laid her head back down on the grass. "That was the best one so far..."

"Do you need help getting back into the water, Kyuumi?"

"Yes. My legs have gone numb from quivering too much," she answered, eliciting a chuckle from him.

Smiling at her straightforward answer, he waded closer to her, and scooped her up into his arms. Cradling her, he then made his way over to a less dirty side of the hot spring before sinking both of them down into the water. Her immediate reaction was to let out a contented sigh while he simply closed his eyes. When he finally let her go, she stayed pressed against him and nuzzled her cheek on his chest, prompting him to go ahead, and wrap his arms around her again.

"You're so... Affectionate whenever we do these sorts of things, Kyuumi," he commented as he looked down at her.

"It's your fault that I get like this... All the pleasure just makes my brain stop working," she said in response, purring softly when he pressed a soft kiss to the top of her head.

Naruto gave her a squeeze. "Mine too, Kyuumi..."

"Mmm..."

"Good thing I don't use my brain that often anyways."

Kyuumiko let out an amused snort. "You might not, but I do. Though... I guess it's not so bad... Not using it when I'm with you."

"That was really cheesy."

"Yeah, well... Hm... What would you have said?"

"I love you."

She blushed.

"Yeah... Well... Love you too, Naruto..."

A/N: I hope you all enjoyed that huge lime and I hope that I balanced out the lewd and the wholesome in this chapter. It took a while to write this because I really wanted to make it good. If you enjoyed and want to give me more motivation, I would appreciate it greatly if you favourited, followed, and posted a review! Anyways, take care y'all!
