Spring of Serenity (Sakura/Corrin from Fire Emblem Fates) (Patreon)

The hot springs were supposed to be a place of warmth, serenity, and not a whole lot else. While those feelings were indeed in abundance, the two individuals presently occupying the waters were not able to focus on those sensations.

The reason was not a fun one.

Both had entered this place expecting to enjoy a scheduled slot all to themselves. Even when they ended up soaking in the same waters, it took a while for them to notice the other’s presence. By the time they finally realized, they had both seen and revealed things they were not supposed to have seen and revealed.

Although neither had gathered the courage to speak up yet, it was obvious that their relationship would never be the same.

Whether that was a good or bad thing was yet to be seen.

Sakura was the first to arrive. Visiting the hot springs by her lonesome was something she never typically did, so naturally, the one time she did do that was when somebody else decided to show up unannounced!

Her usual companions were either Hinoka or Hana. They handled the booking procedure and talked to the receptionist on her behalf, which she was eternally grateful for. Their company also helped her feel safe, meaning she could relax and unwind all that stress from her body without her anxiety flaring up.

Hinoka was supposed to be her partner for this particular session. However, her pegasus had sustained some injuries in the last battle, so her sister’s focus was understandably on her loyal companion’s recovery. Hana was not available either, currently participating in a sparring competition. Although her closest friend would doubtlessly aid her in her hour of need should she ask, she did not want to feel imposing and selfish.

Sakura contemplated not going at all, but the hot springs were popular and slots had to be booked weeks in advance; she wasn’t sure if she wanted to wait that long for another chance! Therefore, she gambled on being able to make it past the receptionist without turning into a stuttering mess… and miraculously, she was able to do so!

It felt phenomenal to submerge her body within those comforting wars, and since she knew she would be alone for this session, she opted to discard any appropriate hot springs attire beforehand. If she was going to have the springs to herself, then why not take advantage of it and try some new things? This was a safe space and she wouldn’t be disturbed, after all!

The ethereal warmth brought clarity to her mind and body, allowing her to forget about the war… and her surroundings as well. She sat back, relaxed, and enjoyed peace, tuning out everything except for how wonderful this was making her feel.

Corrin had arrived a few minutes later. Though he hadn’t planned to enter the hot springs on this particular day, an unexpected request from his older sister changed his plans. Hinoka had informed him that there was a reservation she could not attend due to her injured pegasus, and that he should enjoy it on her behalf and not let the slot go to waste. Since the war was taking its toll on him and he was in dire need of a break, he saw it as a perfect opportunity to forget about all his troubles and duties for a while.

The receptionist had rambled to him about some things when he arrived, but he tuned it out since it was just the ground rules for the facility. No running. No jumping in. Wear appropriate attire. He had heard it plenty of times by this point. Usually, he wouldn’t be disrespectful and listen anyway, but the excitement for the inevitable bliss that awaited his body and mind made it hard to focus on the conversation. His anticipated slot wasn’t for another two weeks, so he was very keen to enjoy an hour of complete and utter tranquility far sooner than expected!

Once he was given the go-ahead, he headed there with haste, opting to discard his clothes before entering. Sure, it was against the rules, but he figured there was no harm. He was going to be alone anyway, so why not indulge in how a hot spring was supposed to be experienced? Frankly, the rules sucked.

He did not notice at all that the hot springs were currently occupied. The abundance of steam was somewhat to blame, but his longing for the warmth these waters provided was the primary culprit.

Sakura did not notice either. She was in a world of her own, enjoying the sanctuary of the springs and the relaxation it provided… while enjoying a different form of relaxation at the same time.

Although she was a princess and had her stature to consider, she was by no means sheltered when it came to certain topics. She sometimes thought about fascinating things whenever she was alone, and while she originally had shame in her curiosities, she eventually realized it was ordinary to have them. Of course, she hadn’t intended to use the hot springs as a place to indulge in those kinds of thoughts and fantasies, but since she was under the impression nobody else was present…

To make matters unknowingly worse, Sakura had chosen to think about a certain individual who had captured her heart. He was a man who she could never be with, but in this private moment, such a depressing fact did not matter.

Corrin did not remain oblivious to the secret hiding within the steam for long. The heat, while distracting, could not hide the unusual sounds he was not accustomed to hearing at such a location. By the time he pinpointed their source, he was rendered speechless.

His little sister was in the hot springs… and very much naked.

But that wasn’t what had silenced him.

Sakura’s legs were spread, her fingers were between them, and her expression was one of pure bliss. Although the steam hid much, he could tell she was naked, and he was mesmerized by the sudden sight of her breasts resting on the surface of the water.

She looked gorgeous, far more enchanting than he imagined her looking underneath her typical attire. Corrin was not ashamed he had inappropriately thought about her a few times before… though being able to see her like this without her knowledge or consent did make him feel guilty.

How had Hinoka failed to mention that Sakura was going to be here too?! Did his little sister know he was going to be here as well? He suspected the chances were low; she wouldn’t have entered the springs nude if that were the case… right?

Corrin could not fathom the situation. It felt like it was from a dream. Had he passed out and was hallucinating this majestic sight?

No. There was no way. His mind could not envision something so beautiful. Though it distressed him to look, he could not avert his eyes. Everything about her naked form was making him feel so dizzy, but in a good way, and-

“Corrin…”

That was… his name.

Sakura-- his little sister-- was moaning his name!

Never had Corrin experienced a shiver while feeling so hot.

The mischievous little sister was still oblivious to what was happening, having closed her eyes to immerse herself further in the fantasies she was having.

This particular fantasy involved a visit from her crush during the night. He would come to her, expressing his concerns and worries to somebody who understood what it was like to have such feelings. He’d show a vulnerable side and she’d reassure him that she didn’t think badly of him for it, and that she’d be there for him no matter what.

One thing would lead to another, and they’d be passionately kissing. They’d feel embarrassed about expressing their feelings in such a way at first, but soon, instinct would take over. They would confess how much they craved each other, and then they’d spend the night together, not stopping until the early hours of the morning…

Or maybe things wouldn’t play out that way. Maybe he’d be up-front and honest about how he craved a woman, and how she was the target of his desires. He’d tell her how much she turned him on, and how he was struggling to hold back. He was part dragon, after all! Their urges were stronger! Probably! That's what she read in a book once anyway.

Regardless, she’d tell him shyly that she desired the same, and that he could do whatever he wanted to her… and then, he’d lose control. He’d pounce on her, and start taking, no, tearing off her clothes, planting many kisses all over the revealed parts of her body. Though it would be overwhelming, she’d still insist on pleasing him in return. He’d then show him his… thing… and it would be so big… but she would still get on her knees and worship it with her lips, tongue, and hands. He deserved nothing more than a good little sister devoted to her big brother.

She suspected she wouldn’t be able to handle it in her mouth for long, but it would be okay. She could offer a hole that could take everything as an apology.

“Cooorrrirrriin….”

Sakura loved moaning his name. It made her feel so hot.

There was an appeal to both fantasies, so she switched between them frequently while tracing two fingers across her clit, moving them around in a circular motion that was gradually accelerating. Although it was a little strange to do this while submerged, the heat surrounding her body complimented everything so wonderfully! She was a fan!

She imagined it was his fingers doing this. He’d tease her, ask her how good she was feeling, and if she wanted him to be rougher. She’d try to answer, but nothing more than a little meep would come out. She’d be too shy to say a thing, but he’d know her answer simply from how wet the proposition would make her.

Corrin would then ask her if she was ready-- ready to take his manhood inside her. He’d be big, and it would be intimidating, but she’d nod her head anyway. She’d feel intimidated and a little afraid, but when so much inevitable pleasure awaited her, she’d nod her head.

Upon feeling the level of humidity and pleasure only her pussy could provide, he’d completely lose control. He’d take her. Make her his woman.

Their family would never know. It would be their little secret.

If only he was actually here, doing those things to her… well, she’d die of embarrassment and shame, so maybe it was for the best he wasn’t!

Corrin, very much present, could not hold back a brewing temptation. This was an unorthodox place to take care of business, but when such a beautiful view was enchanting his eyes and setting his mind ablaze, how could he not? Besides, she was demonstrating just how good it could feel! Sakura was still completely oblivious to his presence… and it would remain that way so long as he came first. It was going to be difficult though-- she had a headstart!

He still could not believe she was thinking about him.

The very thought was mind-boggling. She was always shy around him, and while they had broken the ice a little throughout the last several weeks, this scene was making him wonder if the true source of her timidness was the lust she had for him.

He was not disgusted. He’d be a hypocrite if he was. He was absurdly turned on, all thanks to his little sister. Corrin was already working his shaft, keeping his eyes glued to her and using her beauty to fuel his arousal.

He loved seeing her expression morph into one he had never seen before. He loved the sweat dripping down her breasts. He loved seeing her arm spasming and what it signified.

He wanted her.

…and she wanted him too, didn’t she?

Although it would startle her half to death, maybe it would be a good idea to reveal-

Sakura suddenly screamed, but it was not the cry of bliss he anticipated. It was one of horror… of realization.

She had seen him.

In hindsight, Corrin figured it was probably not a good idea to risk it all just so he could tug it to the sight of his nude little sister, but there was no going back now.

Despite the revelation on her end being loud and aggressive, Sakura entered a stubborn silence, refusing to even look at him. He half-expected her to jump out of the springs and run away… but she hadn’t.

For some time, nothing happened. Neither had the courage to even look at each other. The realization that their relationship was never going to be the same… it was not pleasant.

Corrin understood why she was being quiet. He had caught her during what she believed was a moment of privacy.  A girl like her was probably having an internal breakdown about it.

But he wished he had something to say. Something to de-escalate the situation even a little.

Their scheduled slot was only an hour too. They’d have to leave eventually… and he’d preferably like to depart knowing his relationship with his little sister was still intact.

He just didn’t know what to do though!

Too many possibilities entered his mind, and all of them had flaws and would make him out to be a pervert. Well, she probably already thought she was one, but…

Corrin was at a stalemate, but unexpectedly, it was not him who eventually broke through the awkwardness.

“D-Did…” Sakura started, her voice very quiet, but the absence of any sound for a while made her sudden speech stand out. “D-Did you… l-like what you s-saw…?”

Sakura could not believe what she was saying. It was not like her to say such things!

But being horny changed how a person’s mind worked. She was still unbearably turned on, and not even the man of her dreams unexpectedly being present in the waters with her would change that… especially after seeing how erect he was.

He was hard… because of her!

Not even she, the paragon of timidness, could ignore how much of a confidence boost something like that was. He desired her, just as much as she desired him! Even if he denied it, she knew it wouldn’t be the truth!

Corrin understood that if he responded, it would come out in stutters too, but he did not care. She had shattered the silence. He was not going to let it reign again!

“I… I d-did, a lot, in fact,” he did his best to remain calm. He wasn’t succeeding, but he did not let that stop him. “I, uhm… w-wasn’t expecting you to be h-here, but then I saw everything, and… I liked it-- a lot.”

Goodness. He sounded just like her!

“I-I see…” she mumbled. “W-Well… i-if you want… you could, uhm… c-come closer…”

Sakura was not thinking rationally. Her words were conjured entirely by arousal.

Corrin took a moment to respond, needing to play that proposition numerous times in his head to make sure he was hearing it correctly.

What.

“Sakura… if I do that…” Corrin was struggling to speak. She was inviting him! His little sister! “I’m… not sure I can hold back.”

He wanted her so badly. He wanted nothing more than to smother her with kisses. He wanted nothing more than to hear her moan his name again. He wanted nothing more than to take her.

“...t-then d-don’t… h-hold b-back.”

Hearing her response flipped a switch in his head-- a switch that was holding him back.

Corrin immediately started making his way over to Sakura. He did not think. He knew what he had to do, and as soon as he had access, he met his lips against hers.

It was shaky. It was messy. It was impulsive.

But it was the first of many kisses, and as they grew in intensity, the lingering hesitation and concerns they had faded. They both eventually stood, forsaking the warmth so they could bathe in each other’s heat instead.

Sakura’s big brother wrapped his arms around her, though his hands did not find satisfaction from her back; they soon moved downwards, groping her ass. Corrin’s little sister mimicked his actions, though her hands instead drifted back around, clutching the erect cock that was poking against her stomach.

They were not themselves. They were both consumed by lust.

But they liked that. It made them feel brave. The consequences of their actions? Those could be worried about later.

Even when the need to breathe was too much to endure and they had to separate, Sakura refused to let her hands depart from the dick she was massaging, though she appreciated the opportunity to glance down and see how big it was.

The view was disrupted when Corrin’s hands maneuvered to her front, desiring to feel up her breasts, and the sensation sent the most divine shiver down her spine. Her chest wasn’t particularly impressive, but she was bigger than she looked when wearing her typical outfit. There was a satisfying amount for him to squeeze and play with, and his eagerness indicated he was quite the fan.

Sakura understood what he was feeling. It wasn’t too different from how she was a fan of how big his cock was!

She wanted it inside her.

It was a thrilling yet terrifying thought, but excitement was winning that battle; it had been reinforced by impatience and desire.

Corrin was struggling to multitask, but he was giving it his all to satisfy not just his lust, but hers. His hands refused to depart, wanting to feel up everything her beautiful body had to offer. Sakura had the body of a goddess, and if they weren’t pressed for time, he’d prove that by properly worshiping it.

For now, making out with her while playing with her breasts and butt would suffice. More than suffice! He was addicted to touching her. He never wanted to stop. Her skin was so smooth, and so warm…

Corrin loved how she was jerking him off too! Her hands were the softest things in the world, and the knowledge that it was his little sister touching him was driving him mad.

The two simply could not get enough of each other!

Ever since they had met, they had always experienced a form of attraction toward each other. Even after learning the truth about their heritage, the fantasies never stopped, and now, some very naughty wishes were being granted.

Neither had any idea this attraction was mutual all along, but now that they knew, they were determined to make up for lost time.

Their family would never know. It would be their little secret.

“C-Corrin…!”

Sakura never thought she’d moan his name right in front of him! His fingers had finally decided to tease her most sensitive spot and she was not prepared for it. She was on the verge of orgasm when she noticed his presence, ruining that wondrous build-up… but his touch was doing an amazing job at restoring that wondrous elevation of pleasure.

Especially when he decided to put a finger inside her.

It wasn’t often she did this, so the sudden insertion surprised her, but he remembered to be gentle even through his lustful haze. She always wondered whether or not he’d be gentle and considerate, or rough and wild. The answer was both… and she loved that!

She couldn’t handle it anymore. His finger felt so good inside her, and he was using another to massage her clit, and his other hand was massaging her breast, and he was kissing her, and… and… and…!

“Coorrrrrinnnn!!!”

Sakura came, experiencing one of the most amazing orgasms of her life, and it was all thanks to her big brother. Her legs started to wobble, but he was there for her, holding her while the intensity gradually began to fade.

Though her body longed for recovery, there was now only one thing on her mind.

Corrin deserved to cum too! It wouldn’t be fair if it was just her.

…and well, since her knees were about to give way anyway… what was the harm in letting that happen?

Corrin was startled upon seeing her slip, but the waters thankfully dampened her fall. Before he could question if she was okay, she rendered him speechless for the second time.

But who could blame him? He wasn’t exactly used to seeing his beautiful little sister sucking his cock. By the time he glanced down upon feeling a sudden spark of pleasure radiating throughout his body, his tip was already completely gobbled up. Sakura made it her mission to take in more, and while she found her limit after another two inches or so, he was still amazed that she was even doing this at all!

What had happened to his little sister? Wasn’t she meant to be shy?!

He liked-- no, loved this. He loved that his little sister was as horny as he was, and he loved how amazing this felt. Her mouth was hotter than even the springs, and something about her tongue swirling around his manhood while she sucked in her cheeks constantly, suffocating his shaft… it was unparalleled. She was bobbing her head back and forth at such an impressive speed too! Did she love this more than he loved this? There was a chance!

She was doing such a good job too. He could watch his dick sink into her mouth for hours. Her technique was undeniably messy, but the unpredictability that resulted from it was immensely satisfying. This was Sakura. Sakura was sucking his cock! Corrin couldn’t help but repeat that fact constantly in his mind. It was so unbelievable, and yet, this was reality.

Although Sakura’s determination had never been so high, she was struggling due to his size. This was Corrin’s cock… and it was inside her mouth! She was sucking him off! She was giving him a blowjob!

The constant reminders were making her feel so dizzy, but she adored it. Not only that, but the knowledge that this was making him feel incredible… and that he could cum at any second… well, she wasn’t sure how she was still able to do this in all honesty. She was going to die of embarrassment later, but that could happen after she had learned what his semen tasted like.

“Sakura… I’m…!!”

Corrin couldn’t hold back. The ambush of the blowjob and how incredible it felt… it was too much for him. He had truthfully gotten quite close earlier, the sight of her beautiful body almost enough to bring him over the edge at record speed. He had lost some of that momentum due to her fright, but now after all the kissing, and the way she worked her hands, and had he mentioned how good it felt in her mouth?!

The sudden hotness entering her mouth was startling, but Sakura persevered, swallowing her big brother’s semen without complaint. The load was hotter than she anticipated it to be, and it was quite salty too, but just knowing what this substance was… it was enough to sow the seeds of addiction.

Satisfied she had swallowed everything, she released his cock with a satisfying pop, gazing up at him with narrowed eyes.

Corrin was not done yet. Not after that. “Sakura… stand up.”

Her big brother had a plan. She knew what it was. He was going to take her. Make love to her. Fuck her.

Sakura did as she was told, and as Corrin sat down, she had a feeling she knew what he wanted to do.

“This is your first time, right?”

She nodded. Of course it was! Her first time belonged to the man of her dreams-- Corrin!

“You can take your time if we do it like this.”

Although Sakura felt impatient and way too eager to proceed, she understood this was a momentous occasion and that she couldn’t be hasty. She was about to lose her virginity.

The realization was enough to break through the arousal clouding her mind, flaring her anxiety and making her feel apprehensive.

But it was okay! She knew she’d be safe. He’d protect her, and wouldn’t dare hurt her more than he needed to. This wasn’t exactly the place she imagined her first time to be either, but she liked it! Everything about this encounter was so unorthodox, but that was what made it special.

After inhaling and exhaling too many times to count, Sakura finally started to lower her body onto his lap. It was a very gradual process, and it was a little difficult to see due to the steam, but their most sensitive areas finally met.

Sakura was hesitant to go further, knowing pain awaited her.

But just like how the hot springs cleansed her body and soul, making her aches and worries fade, so too would the loss of her virginity. Clutching his shoulders firmly and bracing herself for the worst, she lowered her body once more.

The pain she felt as his manhood entered her for the first time was… surprisingly tolerable! It was certainly present, but the feeling of fullness as his cock stretched out her insides was a more prominent sensation-- a good one at that! She was grateful, for this meant she could focus on the truth that made her shiver so good-- she was actually having sex with her big brother!

“...Sakura… you’re not hurt, are you?” Corrin asked, admittedly not sure how to interpret that expression of hers. She looked ecstatic, but he wasn’t expecting such a look from her after having taken his cock for the first time. There wasn’t even any blood either… which was probably a good thing considering this was a public pool. They had not considered that in the heat of the moment!

“I’m… ah… o-okay!” Sakura hastily put his worries to rest. “It’s… intense, but… I can… h-handle it!”

That was all he needed to hear.

Knowing they were pressed for time, the brother and sister concluded the conversation, putting their efforts into making the other feel good.

Sakura slowly but surely lowered her body further, taking his cock fully inside her pussy for the first time. The growing pleasure made her head spin, but her big brother was there to support her, offering a shoulder to rest her head upon while she adjusted. Once ready, she started to move, her movements minimal and secluded at first. Even though it didn’t hurt nearly as much as she anticipated it would, that didn’t change the fact that he was quite big!

Corrin did not simply watch. He saw an opportunity to resume something they had been doing a lot earlier. Kissing! The sudden smooch was startling for Sakura, but she quickly embraced the comfort it brought her. Their making out wasn’t as ferocious as it was before, but it was unbelievably passionate, and the way it made his cock throb inside her… she loved it! She loved everything.

And most of all…

“Corrriiinnn… I love youuuuuuu!!!”

Declaring her love while having sex wasn’t something she imagined would happen either, but it would be wrong if she did not say it.

“Sakura… ahhh… I love you too… so much…!!”

Corrin wished he could speak more clearly, but he was having a bit of a breathing problem. Her insides felt way too good. Terrifyingly good! Her walls encompassed his member so strongly, making the friction he felt whenever she moved extraordinarily sensational.

Sakura was accelerating her movements too. The pressure of having her pussy filled up had taken some getting used to, but when moving up and down resulted in pleasure this addicting, how could she not speed up? It was hitting so deep! Never had the entrance to her womb been touched before, but his tip was now constantly pressing against it, invoking pulses of pleasure she couldn’t quite fathom.

But she knew she wanted more, so she refused to stop. Sakura bounced frantically on his cock, fueled by nothing but adrenaline. Her wildest imagination could not have prepared her for how amazing this would feel. Her wildest imagination also could not have prepared her for how exhausting this would be! Sakura did her best to ignore that creeping feeling, wanting to ride his cock for as long as possible, but she was not built for this. After overworking her inexperienced body, she collapsed forward, resting her head once more on his shoulder.

Corrin was quick to take over, replacing his lover’s motions with thrusts that hit just as deep. Sakura breathed heavily as she tried her best to recuperate, though the constant pressure against her cervix slowed down her recovery. It did mean she was moaning a lot into his ear though, so it wasn’t all bad.

Understanding she preferred the faster treatment, Corrin focused his efforts on fucking his little sister as hastily as he could. He grasped her ass while they fucked, focusing all his energy into screwing her silly. Sakura’s cries amplified dramatically as a result, eclipsing even the splashing sounds caused by their lovemaking, encouraging him to go at it with even more ferocity.

Although he wanted to keep at this until they reached their peaks, not even Corrin could ignore the strong sense of fatigue creeping into his muscles.

But that sensation came at a good time. Corrin soon discovered his thrusts were being hindered by another hurdle, albeit one he was pleased to feel clutching his cock.

Sakura was beginning to tighten up. A lot.

She was also shaking a lot. And moaning a lot more. And-

“Corrrriiiinnn… I’m cummmmmiiiiinnggg!!!”

His little sister’s grip on his shoulder had become shockingly strong, but it was easily ignorable when her sudden compactness made him feel astonishingly good.

Too good.

“Sakura, I’m…!!”

Sakura’s orgasm had triggered his own, all thanks to the sensational squeezing her pussy was giving his manhood. She took everything inside her one last time, embracing his member with her contracting walls and bringing him over the edge.

Though she was in mid-orgasm, Sakura could feel the hot warmth filling her up and understood what it meant. Her big brother was cumming inside her!

She liked it, and not just because it was making her amazing climax feel even better.

All of her fantasies ended this way. He’d always cum inside her.

Sakura never believed she’d ever experience the real deal, but now she was… and she couldn’t be happier!

She couldn’t be more tired either. The orgasms, while heavenly, were ridiculously draining.

It was a good thing they were in the hot springs!

After a few moments to gather their bearings, Sakura and Corrin snuggled up with each other, not wanting to depart from the warmth they provided each other.

They did not speak to each other either, but this time, they did not fear the silence. Their time in these hot springs would come to an end soon, but they would leave it with a smile on their face. They could talk about what this encounter truly meant then.

But for now, all that mattered was enjoying the other’s unexpected company. Hot springs reservations had to be done far in advance, after all! They wouldn’t get a chance to do this for some time, so it was best to let this magical moment last as long as it could.
