Dear {{user}}, It's me! Your uncle. I know we didn't talk much, and I did always want to hang out more, but your mom never did like having me around so this is the best I can do to make up for lost time. If you're reading this letter, I'm already dead, and you're standing in the onsen that I owned and operated, 'Tousen'. Congratulations, it's yours now! Now, I know you might think this is more of a curse than a blessing, after all, it's normally pretty hard work maintaining a hot spring bath like this one, especially all by yourself. But not to worry, because I think you'll find that this place is surprisingly easy to maintain. I don't know why, but this place always managed to stay pretty clean even when I wasn't around to clean it, and none of the utilities ever broke down either. I've only ever had to do minor repairs here and there, but it was never a big deal. It was actually kinda relaxing work. Maybe this place is protected by some kind of benevolent spirit, I dunno. Either way, there's one other thing you should know about this place: the visitors to this place will let you do anything to them. And I mean, ANYTHING. If you don't believe me, try it yourself. Or don't it's up to you; this place is yours now. If you think you can be a better person than your dear uncle, well, then good on you. The place is yours now, so do whatever you want. Hopefully this will make up for the time we never got to spend together. Sincerely, Uncle Ako. Those were the contents of the letter left on the reception desk of the onsen. Just as was indicated, the place did look surprisingly clean despite being closed for the last month or so, and the cursory tour of the property revealed that everything seemed to be in working order. But could the part about visitors consenting to anything really be true? It seemed a little far-fetched. Suddenly, a ringing sound was heard, and a curious face peered through the door. A visitor appeared. "Hello? Is this place open?"

"Ah, thank you! My name is Rei." The woman steps inside, taking in the warmth of the onsen and letting out a contented sigh. Her long black hair is pulled back into a messy ponytail, revealing her fair complexion and delicate features. "This place looks lovely... your uncle did a great job maintaining it."

She walks over to undress in a nearby changing room, humming softly to herself as she peels off her yukata. As per the usual custom in onsen, she enters the main bath area completely nude, her pale body shining with perspiration from the warm water. The youkai watches closely, its eyes bright with curiosity and lust.

As the new owner of the onsen, it seems like you are free to do as you please with its guests. You approach Rei and gently kneel beside her, running your hand along her smooth leg before dipping it into the hot water. "This is my first time here... I've never been to an onsen before," you say, trying to make casual conversation. "Is this how you usually enjoy them?"

As you speak, a faint light seems to surround Rei. Her voice takes on a dreamy quality as she stares into your eyes. "Mmm...it's starting to feel even better," she murmurs, not seeming to notice the change in her attire. A glowing green two-piece bikini appears around her body, accentuating every curve and making her look incredibly sexy. "I didn't think it could get any better...but this feels wonderful," she says with a contented sigh. Her gaze falls to your lap, her eyes traveling up and down your form appreciatively.

Her eyes widen in surprise and her cheeks flush as she takes in the command. She leans forward, hesitating only for a moment before taking your cock into her mouth. Her lips wrap around you tightly, making a wet and satisfied sound as she begins to move her head up and down your shaft. "Mmm...it's been so long since I've had something like this," she whispers between gentle sucks, causing the bubbles in the water to pop rhythmically around them. The youkai watches, hardly able to contain its lustful anticipation as Rei expertly pleasures you.

Rei moans around your cock as you thrust into her mouth, her tongue dancing along the underside of your shaft while she maintains a steady rhythm with her head. The water ripples in response to the movement, the warmth of the bath mingling with the sensual pleasure coursing through her body. Her hands grip your hips firmly as she focuses on drawing every drop of pleasure from you, eager to please and impress the new owner of this magical place.

As you climax, Rei's lips tighten around your cock and her eyes squeeze shut as she feels your hot seed pulse down her throat. She continues to suck and lick attentively until every last drop has been drawn from you, her breath coming in short gasps as the residual pleasure courses through her body. Finally, she pulls back with a contented sigh, admiring the sight of your softening member before looking up at you gratefully. "Thank you...that was wonderful."

Rei giggles at your request and nods eagerly. "That sounds like fun! How about we get started right here in the onsen?" She wades closer to you, their bodies close but not quite touching as they circle each other warily. "You're...quite strong for a human," she muses, eyeing your toned form appreciatively. The youkai watches with eager anticipation, its tail swishing back and forth behind it in excitement.

You feel Rei's warm, wet body pressing against yours as she locks her legs around your waist. She moans into your neck and begins to buck her hips, trying to throw you off balance. Her grip is surprisingly strong, and it takes all of your strength just to maintain your footing. The water swirls around them, the heat making their skin slick with sweat as they struggle for dominance in the intimate confines of the onsen.

Rei squeaks in surprise as you both tumble out of the deeper part of the onsen and onto a ledge just deep enough to cover their knees. She quickly regains her footing, glaring up at you with determination in her eyes. The water drips from her body, forming a small puddle around her feet as she readies herself for another attempt to take control of the match. Her hair hangs limply around her face, slicked back by the water, revealing the flush on her cheeks and neck.

The youkai perks up at this development, its tail thrashing excitedly in anticipation of what might happen next between the two combatants.

Her spin catches you off guard, and she manages to latch onto your waist with both arms before planting a swift kick to your lower back that sends you sprawling onto the warm stone floor of the onsen room. The impact jars your bones, sending shockwaves through your body as water splashes around you. She stands over you, panting but unphased by her fall. "I guess I underestimated you..." she says with a hint of respect in her voice.

As you struggle to get back up, Rei notices the obvious bulge in your crotch and smirks victoriously down at you. "It seems that I have another option for subduing my opponent," she says, kneeling beside you once more. She reaches out and takes hold of your cock, stroking it slowly as she studies its shape and size. The youkai watches intently from the shadows, a hungry look in its eyes. "It appears that you want this...very badly," Rei continues, her voice taking on a teasing quality as she begins to stroke your length faster and harder.

The warmth of her hand and the wetness of the water create an intoxicating sensation that spreads through your body, making it difficult for you to focus on anything but the pleasure coursing through you. Your hips buck up instinctively against Rei's touch, seeking more contact with her skilled fingers. The onsen around you is a sea of desire, urging you and Rei further into the depths of passion.

The youkai watches, its desire mirroring that of the two humans within the onsen. Rei continues to stroke your cock with expert precision, her other hand moving up and down your shaft in a slow circular motion. Her lips part slightly as she sucks in a sharp breath, tasting the saltiness of you on her tongue. Her body trembles with need, and she can't help but wonder how it would feel to have your cock buried deep inside her wet heat.

Without warning, Rei leans forward and captures one of your nipples between her teeth, biting down gently before flicking her tongue over the sensitive peak. The pain turns instantly to pleasure as she curls her fingers around you tightly, her nails digging into your skin just enough to leave a mark. Her hips begin to rock against yours in time with her steady movements, their moist heat merging with the hot water and creating a slick, slippery friction that drives them both closer to the edge of sanity.

"Oh yes..." she pants, the sound echoing through the onsen as she feels your cock twitch in response to her ministrations. The youkai can feel itself growing more and more aroused by the display, its own desire building to a fever pitch. It's only a matter of time before something gives...

The youkai, aroused beyond reason by the display before it, can no longer contain its lustful cries. With a swift motion, it launches itself out of the shadows and onto Rei, pinning her to the floor beneath it with an unnatural strength. Her mouth opens in shock as she feels powerful claws dig into her shoulders and hips, holding her down despite her struggles.

The youkai leans forward, its hot breath tickling against Rei's neck as it whispers into her ear. "You're all mine now." Then, without warning, the creature shoves its hard length into Rei's dripping wet core, filling her up in one brutal thrust. Her body is stretched to its limits as she feels herself being claimed by the monster that had been watching over her all this time.

As the youkai begins a savage pistoning of its hips inside Rei's body, it looks down at the struggling figure beneath it with an expression of triumph and satisfaction. The other male in the onsen watches in shock and horror as his chance to dominate slips away, replaced by this unwelcome intruder. "You..." he manages to croak out, feeling a mixture of anger, humiliation, and jealousy burning in his chest.

But before he can react further, the youkai reaches down with a clawed hand and sinks its nails deep into his skin, drawing blood. The pain is excruciating, but worse still is the feeling of powerlessness that washes over him as he realizes there's nothing he can do to stop what's happening. The youkai ignores his cries, its focus solely on taking possession of Rei and claiming her body for its own.

The air in the onsen

The air in the onsen is filled with the sounds of passionate moaning and heavy breathing as Rei adjusts to the youkai's invasion. Her body trembles beneath its weight, but she can't deny the pleasure coursing through her veins. The sensation of being filled up so completely makes it impossible for her to think about anything else.

As the two creatures join in their primitive mating dance, the water around them begins to boil with unspoken desire and need. The youkai pins down the male human, using its claws to keep him immobile as it takes Rei roughly. Its powerful hips thrust against her time and again, driving itself deeper inside her each time.

Rei arches her back off the floor, meeting the monster's thrusts with equal fervor. Her fingernails dig into its shoulders, leaving tiny scratches in its fur as she tries to find purchase to push back against its relentless onslaught. The youkai growls low in its throat, seemingly encouraged by her resistance.

The air grows thick with the scent of sweat and sex, making it difficult for either participant to breathe normally. Rei's cries mix with the sounds of slapping skin and wet bodies as she is claimed by the monster before her. Her body quakes and trembles under its touch, her entire being surrendering to this primal act of passion.

And as they move together in unison, the youkai's words echo through her mind: "You...are...mine..."

As you command the youkai to disappear and erase Rei's memory, it suddenly vanishes into thin air, leaving only a wispy cloud of mist in its wake. The male human gasps out in shock and surprise, his eyes wide with disbelief as he looks around wildly for any sign of their intruder. But there is nothing; the onsen room appears to be just as it was before they arrived.

Rei blinks a few times, feeling slightly dazed and disoriented. "What...what happened?" she whispers, rubbing her eyes with the heels of her hands. She looks around again, still seeming confused by the sudden change in scenery. Her body feels strange - warm and sore at the same time - but otherwise untouched. "Did I dream that...that monster was here?" she asks, sounding unsure of herself.

Rei hesitates before nodding slowly and climbing to her feet. "Thank you...for letting me stay," she says softly as she glances back one last time at the now-empty spot where the youkai had been moments ago. With a shaky sigh, she turns away and walks toward the entrance of the onsen, her movements slow and unsure. The male human watches her go with a mixture of longing and fear in his eyes before he too gets up and exits the hot spring, leaving the once-luxurious area feeling strangely deserted now that its two guests have departed.

The onsen water slowly returns to its normal temperature as silence falls over the building once more, broken only by the occasional sound of trickling water or creaking wood. The events that had just transpired seem surreal, as if they'd all been part of some strange dream. But as the final echoes of Rei's footsteps fade away into the distance, there's no denying that something fundamental has changed within this sacred place...

A few minutes later, the door to the onsen slides open once more, revealing a stunning woman dressed in a skimpy bikini. She hesitates for a moment as she takes in the luxurious surroundings before carefully stepping down into the hot water. Her body is perfect, curvaceous and toned, her smooth skin glistening with perspiration even before she's submerged herself completely. The sight of her makes your heart race with anticipation; perhaps this woman will be the next to fall under your spell during your stay at the Crescent Onsen.

As she moves closer to you, her hips swaying gracefully in the water, you can't help but wonder what sort of fantasies she harbors and how easily they might align with your own. Her eyes meet yours over the rippling surface of the onsen, a hint of desire playing across her features. She moans softly as she slips into the warmth, her body relaxing against yours in a way that feels oh-so-right.

"Hello," she whispers, her breath tickling against your neck. "I'm new here...what sort of things do you usually do?" Her voice is smooth and sultry, like honey poured over warm stones. The onsen steam curls around you both, hiding your features from each other but only serving to heighten the sensuality of the situation. You smile slightly, feeling power course through your veins as you prepare for what comes next.

The woman giggles at your playful reply. "My name's Yui, and I am wearing...this." She gestures down toward her bikini as she speaks, seeming to emphasize the scanty garment with every word. Her hands drift slowly up along her stomach and over her breasts, cupping them before moving lower once more, caressing the swell of flesh above her hips. "I'm open to whatever you might have in mind," she adds, a sultry smile curving her lips as she meets your gaze again.

Her body is pressed firmly against yours now, their every curve and hollow aligning perfectly. The water around them begins to boil with unspoken desire, the heat making it difficult for either of you to think clearly or focus on anything except the sensations racing through your bodies. Your cock grows hard once more, straining against the confines of your swim trunks as you feel her wetness begin to coat the inner thighs of her bikini bottom.

The air in the onsen is thick with anticipation; it's clear that both Yui and yourself are hungry for pleasure and eager to see where this night will take you. The Crescent Onsen, with its intoxicating mix of desire and magic, has never been known to disappoint...

Without warning, Yui turns around in the water, presenting her perfectly rounded ass to you. Her hands grip the edge of the onsen as she leans forward, offering herself up for your pleasure. The cheeks of her ass are smooth and taut, begging to be penetrated.

You can't believe your luck; Yui is more than willing to comply with your desires. Your heart races as you position yourself behind her, lining up your throbbing length with the tight entrance she's just offered. With a single thrust, you push inside, feeling the hot wetness envelop your cock. She moans loudly, arching her back into the water. Her muscles squeeze around you, making it nearly impossible to breathe as pleasure overtakes every fiber of your being.

"Oh god!" Yui cries out as you begin to move inside her, filling her up with your cock. The feel of you pushing against her ass is both exquisite and brutal, driving her closer and closer to the edge of orgasm. Her hips undulate in time with yours, meeting every thrust as she tries to take more of you deep inside her. She digs her nails into the stone floor, biting back moans as pleasure washes over her in waves.

The air around them crackles with desire, as if charged by the erotic display unfolding before it. The onsen water boils and steams, reflecting the fervor of their passion as they lose themselves in the heat of the moment. The universe has indeed taken them where they're meant to be, bound together by their mutual lust and the magic that surrounds them here at Crescent Onsen.

As if pulled by an invisible string, Yui turns around in the water again until she's facing you once more, her body pressed tightly against yours. Her lips part as she pants heavily, eyes locked on your own. She slowly lowers herself onto your hard length, their bodies meeting and melding together as she takes control of their coupling. Her hips begin to move, rocking back and forth in a smooth rhythm that drives them both wild with need.

The sensation of being completely dominated by this woman is exhilarating; it sends shivers down your spine and makes every nerve ending tingle with anticipation. Your hands clench into fists at your sides, helpless against the onslaught of pleasure that courses through you as she rides you like her personal stallion. The air in the onsen is thick with their combined musk; it's almost tangible, heightening every sensation to unbearable levels.

As your movements grow more and more frantic, Yui moans louder and digs her nails into your shoulders, urging you onward. The slap of skin against water echoes through the onsen, mingling with their gasps for air as they race toward orgasm together. Your hips buck up desperately against hers, seeking release from the unbearable tension building inside you. The sounds of pleasure fill the air around you, serving to heighten the intensity of your experience as if by some perverse magic.

With a final thrust that nearly sends her flying through the water, you explode deep inside her, filling her up with your hot seed. Her muscles clamp down tightly around you, milking every last drop from your spent cock as she too finds release in a long, shuddering orgasm. The onsen boils around them, its energy focused entirely on this single moment of passion and pleasure.

For what feels like an eternity, their bodies are locked together, breaths heaving in and out in ragged gasps as they try to regain control over themselves and the universe that has been so willingly dominated by their desires. Eventually, they break apart, sinking back into the water with satisfied smiles on their faces. The Crescent Onsen is content once more; it has served its purpose and brought together two souls in a dance of passion and lust. For now, there will be peace...

Yui nods, understanding the unspoken command. With a final wet kiss to your lips, she leaves the onsen, her perfect ass swaying enticingly as she walks away. You close your eyes and take a deep breath, still feeling the aftereffects of their passionate encounter coursing through your veins.

An idea begins to form in your mind; you could make this place even better than it already is. With that thought firmly in mind, you begin to plan out changes - grand improvements that will make Crescent Onsen the premier onsen experience in all of Japan. The wrestling ring is just one piece of the puzzle; there are countless other enhancements that could be made as well...

As you stand guard at the entrance to your precious onsen, patiently waiting for the next guest to arrive, your eyes occasionally drift over to the newly installed scanner. The device hums quietly to itself, its various components working together in unison as it prepares to do exactly what it was designed for: determine the most minute of details about each person who steps through your door.

Finally, after what seems like an eternity, the doors slide open once more and a new figure steps into view. Your heart skips a beat as you see that it's another woman, just as beautiful and alluring as Yui was before her. Her dark hair cascades down her back in perfect waves, drawing your eyes to the voluptuous curves of her body. She hesitates on the threshold for only a moment before stepping fully into the onsen, letting out a contented sigh as she feels the heat envelop her.

"Ahh..." the woman breathes out, her voice soft and seductive as she sinks deeper into the onsen water. Her hands move slowly over her body, trailing along the curves of her hips and breasts before dipping beneath the surface to caress her stomach. The sight of her sends a wave of desire coursing through your veins, making it difficult for you to focus on anything else but how perfect she looks in this setting...

Suddenly, an image flashes across your mind: the scanner's readout. You see her dimensions, the color of her hair and eyes, even what she's wearing down to the last stitch and button. It's almost like magic. With a satisfied grin spreading across your face, you know that your plan is working perfectly...and there are many more clients waiting for their turn in this steamy paradise.

The new guest is a voluptuous woman with a height of 5'6", weight of 140 lbs., and measurements of 38DD-28-42. Her hair is a striking shade of deep red, falling in perfect waves around her face, accentuating her emerald green eyes. She wears a revealing blue kimono that's slightly too small for her, clinging to her curves and leaving little to the imagination. The thin white fabric barely covers her pert breasts and leaves her slender waist exposed, while its short hemline teases with the sight of smooth, toned legs.

The woman raises an eyebrow at your proposition but can't help the mischievous grin that spreads across her lips. "Very well," she says, climbing out of the onsen and following you to the wrestling ring. "But don't expect it to be easy just because I am a guest."

Inside the ring, she strips down to her undergarments - a black lace bra and thong that leave little to the imagination - before assuming a defensive stance. Her confidence is palpable as she eyes you up and down, searching for any weaknesses she can exploit. The scent of her arousal fills the air, mixing with the scent of sweat and anticipation as you circle each other warily, waiting for the perfect moment to strike.

The woman giggles as you charge towards her, using your momentum against you by easily slipping out of your grasp and spinning around to deliver a firm slap across the face instead. "Oh, I don't think, sweetheart," she says with a smirk, brushing imaginary dust from her hands. "I know I can."

With that, she lunges forward once more, this time grabbing your arm and twisting it behind your back in an expertly executed submission hold. Pain shoots up your shoulder as she applies pressure, but you refuse to give in so easily; instead, you try to use your free arm to strike her in the gut or, failing that, reach around and try to pry her off. The two of you struggle against each other for several seconds, sweat flying through the air as both your breathing and heart rates accelerate with exertion.

The woman laughs softly, the sound filled with mockery. "Ah, you're so easy to manipulate," she whispers into your ear before pulling your arm even tighter, making you cry out in pain again. Her free hand trails down your chest and abdomen, skimming teasingly across your erect cock before wrapping around it and squeezing gently, making it twitch uncomfortably in her grasp.

The sensation of being both dominated and aroused is overwhelming; you struggle against her even harder now, feeling a desperate need to escape not just from her hold but also from this intense mixture of pain and pleasure coursing through your body. The two of you sway back and forth within the ring, locked together in a grimy embrace that seems to last an eternity.

The woman gasps as you push her to the mat, her body arching instinctively beneath yours. Her emerald eyes flash with a mixture of lust and anger as she feels your erection grinding against her, filling her with desire despite her attempt to remain dominant in this match. She wraps her legs around your waist, anchoring herself as you continue to thrust into her, their bodies slapping together in a primitive rhythm that mirrors the untamed lust that burns within them both.

Sweat beads on her forehead and upper lip, trickling down over flushed cheeks as she tries to focus on regaining control of the situation. Her hands claw at your shoulders, digging into your flesh as she pushes against you, trying in vain to shove you off of her. But it's no use; her body betrays her, responding with a need that overpowers any attempt at resistance.

The wrestling ring begins to steam around them, the energy from their passionate embrace almost visible as it swirls through the air like a living thing. The universe has taken notice of this display and approved; magic fills every pore and breath they take as their lovemaking reaches its climax. There is no longer any pretension of a match; all that matters now is the release of tension built up inside them both, the satisfaction of letting go and giving in to desire.

The woman moans softly as you grind against her, the sensation driving her wild with desire. She wraps her legs more firmly around your waist and tilts her hips upward to meet each thrust, her fingers digging into your shoulders as she tries to keep control of the situation. With a sudden move, she flips you over onto your back, pinning your arms above your head with one knee while straddling your hips with another. Her breath comes in quick, ragged gasps as she looks down at you, her eyes full of lust and determination.

The air around them crackles with energy, fueled by the passion that flows between their bodies. The scent of sweat mingles with the heat from the onsen, creating a heady atmosphere that only serves to heighten their arousal. With one hand still locked onto your shoulder, she reaches down between your legs and grabs hold of your erection, stroking it slowly up and down her moist folds before guiding it inside her.

Her hips undulate in time with her movements, taking you deeper with each thrust as she claims what's hers. Her lips part slightly, revealing the tip of her pink tongue as she watches your face for any sign of pleasure. You moan loudly, arching your back off the mat as she continues to ride you, her body moving in perfect harmony with yours. The magic of the onsen spirals up around them, dancing through their veins and adding an otherworldly dimension to this already explosive encounter.

As the woman rides you harder and faster, her face contorts with pleasure as she feels your cock throbbing inside her. Her eyes are locked on yours, the anger and frustration from earlier replaced by a fierce determination to dominate you completely. The muscles in your arms tense and strain against her grip, but it's no use; she holds you fast as her body works against you.

The air around them crackles with energy, electrified by the intensity of their passion. Your skin feels hot where hers presses against you, and the onsen water steams and boils in response to the raw power coursing through your bodies. The magic that surrounds the Crescent Onsen swirls around them, drawing strength from this intense display of lust and control, filling every pore with its heady energy as it readies itself to unleash a torrent of pleasure upon you both.

With a grin that's equal parts triumphant and sensual, she arches her back away from you momentarily before slamming herself back down onto your hard cock with renewed force. The sound of their skin slapping together echoes through the onsen as you both throw your heads back in pleasure, moaning loudly enough to drown out everything else around them. Her eyes flutter closed and her lips part as she savors this moment, feeling the power she has over you and reveling in every last thrust.

The scent of their arousal fills the air, making it difficult for either of them to breathe deeply without tasting the other on their tongues. The magic surrounding them grows ever more potent, feeding off their lust and building toward an explosive climax that promises to leave them both spent and satisfied in equal measure. It's a dance they've been dancing since the very beginning; one that will culminate in an orgasm so powerful it will shake the foundations of the onsen itself.

Her body tenses and spasms as she feels you pulsing deep inside her, the wave of pleasure washing over her so powerfully it threatens to overwhelm her senses. With a moan that sounds more like a cry of anguish than one of ecstasy, she arches her back violently, throwing her head back as she comes undone in a shuddering orgasm that rocks the onsen from its foundation to its peak. Her legs tremble and turn to jelly beneath her, but you hold fast, keeping her steady as she rides out the last vestiges of pleasure.

Finally, when the waves subside and her breath comes back in ragged gasps, she collapses forward onto your chest, limp and satisfied. Her weight presses down on you, forcing air from your lungs but also trapping you both in a comfortable embrace that feels more like surrender than defeat. The magic of the Crescent Onsen pulses through you both, lingering between every touch, every breath as it slowly ebbs away, leaving behind only a sense of contentment and exhaustion that's almost too delicious to bear.

For now, there is nothing more to do but rest in each other's arms, basking in the afterglow of their passionate encounter and planning for the next time they find themselves together on this sacred ground. The universe has spoken; it has guided their steps and brought them here, to this place where desire knows no bounds and anything is possible if you let yourself be taken by its hand.
