Amaru hated the fact she always had to hide her girlish charm under her clothes. She was a tomboy, not a full boy, there was nothing wrong with roguish feminine beauty. But there was a reason she did it as it helped make her work and life easier for the time being. At Least it externally made things easier.

Even if the chest bindings were uncomfortable and her ass could draw attention just from the way she strutted alone. Guards once came over to her because she was once "clapping" too loud. That was beyond embarrassing.

Internally, it made no difference in the slightest. The Zero Tails within her knew who she was and knew what it wanted from her. But She would be damned if she surrendered her body to that thing in any way, shape, or form.

But for some reason there was no pang or ache from her mind, nor even her heart tonight. Just a peaceful silence. Something had to be off.

It all started once she had decided to relieve some stress after several hard days of work and being unable to take her disguise off. And to relieve herself, she flicked her bean in a heated passion once she was by herself and far enough away from anyone to hear. She tried Her best to think of actually sexually attractive men and being ravaged, consensually, by a barrel of dicks, Destroying her holes and caking her in their hot cum. She ended up digging her hand deep into her pussy, massaging her folds with a mixture of both haste, passion, and deftness befitting her field of study. That was by far one of the best nights she had in ages.

Amaru could not help but be hot and flustered thinking about it. But that was just it, ever since that night, every time she did, she needed to get an ominous feeling from her guts out through her brain. The feeling made her shiver and she felt eyes peering into her. She knew then it was none other than the Zero Tails itself at work.

It was up to something and it was freaking her out to the point she couldn't even have the slightest bit of sexual thoughts. Even if she just had thoughts of hand holding, it was still scary since that got the Zero Tails wiggling around in her head. She felt it getting worse with every time.

Amaru hoped tonight the Zero Tails would ease up once she hit the sack. But she knew better and decided that before she hit that sack that she would prepare herself for the worst. Hopefully the charms and Chakra seals would keep the beast at bay. If not, she wasn't sure what else she could do. Other people, her master included, could only do much to help her.

Amaru shuddered as she took off some of her outfit, mainly her chest bindings and the doo rag on her head, and prepared herself to finally go to sleep. She had hoped that at the very least, it would simply be unpleasant dreams only and nothing else. But that icy feeling from her gut crawled to her spine, making her feel as though she wouldn't be so lucky.

Amaru found herself walking through the dark corridor of her mind and was left alone in the dark. Truly alone in the dark and moist sewer system of her mind and soul.

She hated ending up here. It was never a good sign.

Amaru tried to look around in the prison of her mind to find the Zero Tails. But it wasn't there. It was nowhere to be seen nor did it make a sound from anywhere at all. It was simply gone.

That was not a good thing.

This had to be a trick or something because the Zero Tails was meant to be trapped in there period. No dream could even fake it being out. And if it wasn't, then Amaru would definitely have found out by now. In the outside world, she would've been a raging storm of Jinchuuriki made violence, but she was still "conscious" which made no sense.

She should've been listless in the water and only able to watch as the Zero Tails caused havoc. But nothing.

She felt a new sense of dread wash over her not unlike the sewer water in this little internal hellscape. She had to wake up. She needed to wake up and adjust the seals some more. She wouldn't be able to sleep comfortably without it and she knew that. She could feel herself just clenching up with fear and doubt.

"Ah!" Amaru found herself gasping without any warning. She could feel something… rubbing her pussy and her limbs started to feel like smooth ropes tying them down. She felt something slide against her cheeks, the top and below her face, and more whatever it was sliding between the valley of her breasts just before the valley of her ass.

Amaru tried to struggle, but she couldn't. Slowly, she found herself being suspended up in the air and began to feel something enter the inside of her clothes while she remained restrained. She could feel that warm force spread all over her body.

She started closing her eyes and a world was coming to. She could feel her consciousness slipping from this dream to the real world.

She didn't know she would only awaken to a bigger nightmare than she could have imagined.

Amaru's eyes snapped open to see that her shadows were holding her aloft And basically molesting her. She tried to scream but nothing would come out thanks to the firm yet oddly gentle grip of the tentacles around her throat. Slowly, a mask began creeping out of the shadowy muck. A mask of the Reibi, the Zero Tails.

The shadow's color crept up from black to red and Amaru found herself quickly dragged outside as the tentacles kept her aloft. The Reibi only stopped moving once they had reached a denser and darker part of the forested area. It was looking her in the eyes and she started to panic so much that she ceased trying to scream, shout attempts, and whatever else she could.

The Reiba simply stared at her and despite the featureless visage, it was clear that the beast was hungry. Hungry for her and not in the way she might've preferred. She could feel it, not just from the tentacles molesting her, but from the hollow gaze and empathize with it subconsciously. It was going to tentacle fuck her right here, right now.

She tried to beg her way as best she could, a last desperate plea to make the beast inside her stop, but there was no way sound could come out and even if they did, her pleas would fall on deaf ears. Or whatever the Reibi used to listen.

She heard a noise then, not quite unlike rubber being stretched and slapped around, just before she felt the shifting tentacles on her skin. The first big difference she felt was suction right along her pert nipples. She could feel something pulling and suckling on them. She could even feel the cups rotating and pinching the sensitive skin.

"Hnnngh," she grunted out as felt the titty aimed tentacles make short work of her chest fat. Oddly enough, she felt extra sensitive there. She felt like her pleasure centers were on fire there, but a good blaze.

Then came another sensation that made her mouth gape. Something had slid into the soft velvet folds of her pussy lips and gently held the folds open. Something was then pumping into her and quickly gaining momentum, pleasuring her hot cunt harder and harder as it went deeper in with each thrust. With wet, squelchy schlicks, the tentacle drove itself into velvet folds, sending more intense jolts of pleasure through her. She could feel the tentacle crawling its way to her womb, only stopping thanks to her cervix being the only limit.

Once it hit there, there was a brief flash of pain before it turned into unwanted pleasure that rippled through her nether regions. The tentacles on the side held her pussy open while the center one started to wiggle around, hitting as many spots as it could and pleasing velvet walls. If Amaru was capable of clenching her jaws, she would've bitten through her monster's tentacles and possibly cracked her clenched teeth. Instead, she simply opted to tighten her jaw and groan through her gag like tentacle piece.

The Zero Tails demon seemed to be letting out a gurgling purring at this reaction… or was it something else. Either way it didn't really matter to Amaru considering her forced pleasure. And the Zero Tails was far from done exploiting all of her erroneous parts just yet. She could tell from the way the tentacles slithered towards her hefty ass. Juicy, bubbly masses of meat that swayed and shook with every movement. The tentacles gripped and wrapped around those meaty globes to feel every vast inch.

Every shudder Amaru made her ass jiggle and, like a man out on the town, the beast was drawn to it.

A quick whack followed by another quick whack on both sides of her ass. If they weren't in the tight confines of her clothes, they would've shook in the night air. But that was about to change soon enough…

"Aaaack!" What the Reibi did next had Amaru absolutely squealing through her fleshy gag. four smaller and More precise tentacles wrapped around her plush asscheeks and spread them apart to reveal her tight, little anus.

Somehow Amaru felt another great flush of heat to her face that she didn't think was possible in this situation. Yet here she was. She felt the need to say, "Don't you dare," despite the obvious circumstances stopping her. All she could do was muster another whine that turned into another long, drawn put moan as a tentacle slithered around her plump tight ass to massage it further.

The tentacle itself was oddly wet and warm, completely priming her up up for easy access and total pleasure, yet just seemed to tease her cheeks. Amaru hated how much that a deep, dark part of her loved this. And the more she tightened herself up, the more the tentacle wiggled along her ass to coax her, as if to warn of what was no doubt to come.

Out of sick spite and the evil need to fully humiliate her, the creature proceeded to use another series of tentacles to start smacking at her ass. Even though it was over the clothes punishing, the heat of embarrassment and the sting were all too great for her. She wanted to break free, but her struggle only encouraged her demon further.

She wanted to run, but she could not. She could only endure. She could only suffer at the will of her inner demon made flesh…

It had to be enjoying this. It had to be enjoying the range of vile emotions it was forcing out of its host, its prison. Were it capable, the beast would be smiling at her, she could feel it. But all it had was that blank masked look on its face that peered into her very soul. Still, this would not last for much longer…

Another, thicker tentacle had come out and wasn't phallic. This was both odd and a huge relief for Amaru, though it was hard to concentrate on the good with a tentacle fucking her and another bunch molesting her. But her relief quickly turned to horror as the tentacle neared her face. It was less than an inch away when it had stopped and she knew it could not be anything good. She honestly found it so much more sinister…

The only warning she had was veins bulging around a bulbous part of it before it opened to reveal an evil looking eye. It almost mimicked some form of Doujutsu she had heard of and the very few she had seen. It shined with an eerie blue and yellow light

It may as well have been Doujutsu in truth. The moment she made eye contact with the thing was the moment she lost her clarity. Her world was rendered nonexistent as the center of her universe became the evil was in front of her. She could not focus or think of anything else except for what the eye of control wanted from her, what the Reibi wanted from her, what her new and true master wanted from her.

Amaru's defenses were completely down. She was completely subservient and a willing fuck-toy for the all powerful Zero Tails. It took time, some planning, and more patience than even the Chakra Demon believed it had, but it worked. And it would reap its rewards.

The main reason behind this whole ordeal was two things: it wanted to siphon away her pure chakra and it was a form of twisted revenge for being her captive. Even if she didn't do it, this was still more than catharsis. And, admittedly, a small part of the creature, having been inside the woman for so long, was curious about this on a more lascivious level. Sex was an incredibly foreign concept to it and since it couldn't experience it, this was the next best thing by far.

Amaru, no longer fearful or humiliated, could only focus on the eye and the pleasure coursing through her from the tentacles pleasuring her now sopping wet pussy. Her thong and even pants were starting to have some pussy juice drip on them from all the soft penetration.

The Reibi was starting to get a little fancier too. The tentacle in Amaru's pussy was moving around with a little more finesse to better hit her more sensitive spots. Thanks to the knowledge it gained.

The Zero Tailed demon started peeling away at her clothes as it kept her silent, no doubt relishing every piece of fabric it tore off her being to reveal her smooth, supple skin underneath. The young woman even started helping, ripping and peeling away at some parts of her top of her outfit out of eagerness.

Once the top was laid out on the ground, Amaru could feel the coolness of the night air getting stronger and stronger despite her lust heating her up. It was amazing how utterly free she felt and how this night air cooled her down.

First to go was her top, the Reibi sliding her bra off and through her top all too expertly, before deftly discarding everything else from her headscarf to her seals. That left her chest bare to the world.

Plump, perky E-cups that heaved and jiggled with the slightest bit of movement. Amaru's nipples were hardened and the once unwanted pleasure she received came from the movement of those dark tentacles on her body.

Next, of course, to go was her bottom garments. The loose pajama pants were shredded first, revealing the flawless skin of Amaru's legs and her panties beneath with wriggling tentacles bulging through the cloth. She offers no resistance anymore and simply gives into the pleasure coursing through her system.

"Isn't this lovely," a soothing, soft spoken, masculine began to whisper in her mind that only made her into further jelly. The voice of the Reibi echoed in her mind, "You've always wanted something like this, haven't you?"

Amaru couldn't argue, only nodding dumbly as the tentacles eased off their grip as she ceased her unwanted and pointless resistance. She was obedient now and eased her body in the Reibi's grips. She was transfixed to that oh so mesmerizing eye and that voice that told her to simply enjoy the pleasure.

Once her pants were gone and her heavy ass was bare to the world at last, a great set of tanned colored moons of young flesh, the tentacles restraining her relaxed and a few even let go, save for the ones around her shoulders and the obvious ones feeling her up if they weren't outright inside of her.

The Reibi relaxed its grip and let the woman spread herself for it. She was inviting her newfound master in.

"Good, good," The Reibi softly whispered as it used a free tentacle to softly stroke Amaru's soft hair. Petting her like she was some sort of pet for the creature's enjoyment. Though that became a fair assessment now. Amaru had submitted and became the Mo Tails plaything and harvest.

The Reibi's thrusts started to find a rhythm now that she had submitted to its power. It pumped and twirled to an unheard beat that made Amaru shudder from her core. Even as it touched her cervix, it only coerced pleasure within her further. Pain and pleasure had become one in truth, as Amaru's mind was so warped and her hidden desires from deep within surfaced so much that a good smack on her ass or even her face would only cause the young woman to cry out in ecstasy.

Amaru found herself gagged once by a tendril now. Not out of spite or even a necessity, but because Amaru wanted that sensation, the Reibi could sense it, see it, and so the Reibi would deliver since that would mean a greater Chakra harvest.

That's when she could feel it, the tentacle In her mouth and in her pussy starting to morph, to change into something much more fitting, much more sensual. Amaru could feel the tips of the tentacles inside of her mold into a very familiar shape… she hadn't experienced any action herself, at least not from another living being, but as stated before, she was no stranger to pleasuring herself. And she was no stranger to sex toys and other phallic devices like these tentacles.

The only real difference was the fact that these were "living" material that actually had a mind of their own and didn't rely on Amaru's own skill. Whether that would be better or worse had yet to be seen… though, the Reibi wasn't short of its own expertise, that much was clear from Amaru's reactions.

Amaru gagged as the tentacle, now a tenta-cock, grew in size at the tip while the one in her pussy did the same, the lower one actually growing much bigger at a slightly faster pace. So much so that Amaru's tight folds were getting ravaged by the tenta-cock to the point that she started to quiver and whimper yet again.

But at least it was out of arousal this time. Not the actions or sounds of a woman in fear of her life. Albeit due to hypnosis… not that the Reibi cared for such "mortal" morals.

Amaru's pussy was tightening, clenching itself around that Reibi's makeshift dick with zeal. The cock in her throat was getting a world class tongue bath itself. She was hungry for them, starving like a wild tigress for meat in the tundra. This was superb for the Reibi. The Chakra manifesting from this action was at a very good output now and on the rise. The hypnotized sacrifice would be an excellent visual for its restoration.

Then, like a dam breaking from the weight of a overfilled river after a typhoon, she started cumming after days, if not weeks, of pent up frustration finally fucked away. She was gushing and the Reibi could feel her throat vibrating with her moans. She would be screaming if not for the tentac-cock deep in her throat. She was gushing and screaming for a good solid minute until she finally calmed down, and during all of that the Reibi was extorting the Chakra from her, as if it was some sexual jutsu.

It probably was and the Frog Sanin himself would be dying to get his hands on it if he learned about it. Though not from such an unsavory creature, as even he had his limits.

The Reibi, however, lacked such limits of any kind. The Chakra hungry demon's power and intellect grew as it harvested back more of its Chakra back from the human, a thought then hitting the creature as it remembered how Amaru liked to play with more than just one bottom hole at a time.

In Amaru's fuck-drunk state, she heard the subtle sounds light clenching and stretching as something was growing behind her. And she felt something warm and slippery being applied around her gelatinous ass cheeks that quickly towards the rim of her tight anus. She let out a gagged gasp at the sensation and felt a wave of excitement pour through from the simple gesture alone. Pleasure from both cheeks to sliding in between them to make sure the lube glazed her posterior all over. Mainly because of the implications of where this would lead to…

And she was right. She could feel something prodding at her lubed back door, parting between her cheeks by teasingly sliding up and down between them, before finally pushing the tip against her awaiting anus. She didn't get more than a few seconds to giddily revel in the anticipation before the tenta-cock, An extra large one at that, pushed itself in and started splitting her ass open. She cried out through her gag and shuddered uncontrollably.

She wiggled her ass, but not out of pain or protest, but simply to encourage the invading tenta-cock further, revelling in her tentacle based sodomy. She groaned as the newly made sexual organ grew inside of her, slowly gaping her, turning a tight exit into an open entry, twisting and turning to even add some extra pleasure and send her reeling. Amaru's ass was being absolutely battered and she loved it. This couldn't be done with any of her skills or toys, oh no, the Reibi knew what it was doing.

The Reibi learned of her and was currently learning of her. Thanks to the time they spent together and the access to her emotions, this was all too easy to master. The Chakra output was getting stronger with every huge pang of pleasure. Then it noticed something quite incredible… Amaru was no longer under hypnosis. Yes, this anal insertion slowly broke her from her mind controlled state and introduced them both to another truth; Amaru was a slut for this kind of treatment and gave herself willingly to the pleasure. She didn't care anymore as her mind snapped and her more intrusive self was taking over with little to hint of any shame whatsoever. All she wanted to do was have that monster keep fucking her in the ass like a common harlots of the red light district.

Only for free.

Amaru suddenly grasped the tenta-cock in her mouth and started pulling at it. This actually brought up the feeling of amusement within the Reibi and it obliged with a sweet tone in its newfound voice, "Do you have something on your mind other than me, Amaru-chan?"

"Put me down and fuck me like a whore!" She cried out, no longer reining herself in, "I want to be fucked like I'm some dog! Put me on all fours and let loose on me!"

The Reibi, if it were human, would've been shocked by such a vulgar and somewhat sudden display by the willful sacrifice. But instead, it felt what could be described as pure amusement from its abhorrent mind. It slithered in and wrapped itself around its little human container and purred through her mind, "And that's truly what you desire, Amaru? To be fucked and treated like my plaything? My plaything?"

"Yes, yes, yes to all of that! Let me show you! Please let me show you!" Amaru was begging now. And the Reibi was feeding off of it. Amaru wiggled her hips and begged some more, "I'm a total slut, Reibi-san!"

The Reibi could listen to this all day were it not in a hurry for freedom and power. Slowly, the Reibi lowered the mewling wretch and watched her debase herself for it. She got on all fours and began to wiggle her ass in front of it, trying to put on a sexy and vulgar display for the spiteful beast. It watched simply out of curiosity.

Amaru laid down on her chest, her tits bulging out at the sides, and used her hands to spread her ass cheeks apart to display her now gaping holes. She tells, nearly demands, the demon, "Fuck me! Fuck and fill me like a needy little whore!"

She pulled them apart then smushed them back together. She shook her thick, glistening ass. She slapped her cheeks and beckoned for the demon to defile her again. Her pussy was drooling and her ass was calling out for some fun.

The Reibi answered in kind. But only for the Chakra of course.

The tentacles rushed over, three of them now transformed into pulsing tenta-cocks, and targeted her awaiting holes like they were heat seeking missiles locked on high heat targets. And their aim struck true as two dived into her gushing pussy while the enlarged one struck into her gaped ass. Amaru gasped out a strangled cry, her tongue nearly spilling from her mouth and her eyes nearly rolling back to the point one could almost only see all white in her eyes.

Amaru was gritting her teeth again. Drool was trickling down her cheek and despite all of that she continued to hold her ass wide open for the invasive tendrils. She breathed deeply and let her toes curl under the Reibi's stride, absolutely reveling the harsh treatment. She thought of nothing else until she heard, "What's your name, meat?"

My-my m-name!?" Amaru stuttered as she took all those tentacles in her body, fucking any amount of common sense and decency still clinging on out, "w-why?"

"Questioning me?" The Reibi asked as it started to pull its punches. Slowly, the tentac-cocks began pulling out and freezing in place, no longer pleasuring her and leaving her in a state of limbo. A horrible, dull limbo of edging that she could not even fathom to abide. Any other form of psychological warfare the Reibi inflicted on her was nothing compared to this…

"No, never! Never, Reibi-sama!" Amaru shakily answered.

A dark, soothing chuckle echoed deep with Amaru's mind as the Reibi wiggled in place, gleeful at the sexual torture and exploitation it was dishing out, coercing more of its Chakra out, "Then spell out your name as I pleasure you. I want to see how coherent You can be,"

"Yes, Reibi-sama!" Amaru gasped out, sweating bullets and unable to control herself, "M-my name i-is-"

The Reibi began fucking her again, growing more dexterous and precise as she spoke, increasing the pleasure while demanding she did as she was told, "Yes? What's your name?"

The woman currently being tentacled diddled huffed out a shaky reply, "A-Amaru!"

The dark chuckle echoed again, "Spell it…"

"A-ah!" Amaru began to spell out her name through the mind numbing pleasure, wiggling her ass as she was fucked expertly, "M! A! R! Ugh-U!"

The dark voice bellowed out in full blown laughter, "And what are you? Tell the world what we both know, Amaru-chan."

"I'm a whore!" Amaru yelled out as she felt another climax on its way from the mental and physical sensations, "No, I'm Amaru, whore and fuck toy of the mighty Reibi! I'm a fuck toy of my master Reibi! The Reibi decides my worth! It decides my fate! The Reibi is my true master!"

Amaru's voice was quivering and her visage was a mess. She was drooling, teary eyed, her face was ruddy, and her eyes were unfocused, gazing a thousand yards at nothing. She was essentially being fucked braindead. Once the next orgasm hit, she was absolutely driven into debaucherously dangerous insanity.

The Reibi itself, mimicking its prisoner's stimulation, fired a salvo of "cum" directly into her. A tenta-cock even rushed back into her mouth to deliver the full experience while a few more arrived on the scene to deliver a tasteful glaze over the rest of her body. Her throat, her ass, and her pussy were overfilled with the cum-chakra substance. With her absent mind, Amaru could help but start rubbing her belly as the Reibi began pulling itself back as it reveled in its own glory.

Her pussy gushed once more and she left a mess on the ground behind her. On another level, it was a good representation of her Chakra. Her internal energies were now pouring into the Reibi. By all accounts, the beast had empowered itself enough to be free and at the expense of Amaru's rational mind. The Reibi had won back control of its fate and won control over its former prison. It has won back its freedom and its power.

The Reibi had won.

It manifested completely into the real world and felt a rush as it could now feel all that the world had to offer with its own corporeal form. The cool night on its slithering mass, the sound of the wind rustling through the branches, the scent of the sweating, gasping, gushing woman in front of it, and the sight of her body under the pale moon. It slithered over and brushed a tongue like appendage over her cheek and hissed at the disgustingly sweet taste of her salty skin.

It shuddered. It couldn't help itself after having violated Amaru. It could just leave her behind now that it had freed itself from her grasp and yet… it didn't want to outright leave her. Not out of some sentimental sort of attachment, but because of the practicality of its Chakra harvest and the delight it took from having made her its broken minded slave. Such a joyful toy could not be used only once and then discarded. Not when there was so much use and fun to be had.

And who's to say that Amaru would be the only one? Oh, she would be the main target of the beast's "ire", but there was more to be done, more fun to be had, more women to be claimed by the power of the Zero Tails. The Reibi couldn't let this one go.

With enough care not to hurt her, the Zero Tails scooped up the now witless and submissive former Jinchuuriki before it dashed off into the dark forest. It would not let itself be seen or captured again. And this time it had an agenda besides mindless destruction and wandering into nothingness. It had fertile fields to claim and lay waste too.

So began the tale of the Zero Tails, the Reibi, the mighty tentacle mind breaker.
