Chapter One: Tentacle Girl Rukia

Rukia Kuchiki sped through the streets of Karakura Town, seeking a hollow. She was a petite, dark-haired girl with little in the way of curves, and held a beautiful white sword in her hand. As she made her way through the streets, she found herself drawing closer to her quarry. Eagerly she pressed on, looking forward to completing her mission. Then she sensed a familiar power and halted.

'Oi, Rukia!' came the call. Rukia looked to see Rangiku Matsumoto approaching.

'Lieutenant Matsumoto,' said Rukia, sheathing her sword, 'I wasn't aware you were here. May I ask why you are out here?'

Rangiku was taller than her, prettier than her and had much longer, softer wavy hair that was auburn in color. The ways in which Rangiku was superior to her did not end here. She wore a low cut black robe which showed off her massive breasts and clung to her curvaceous hips tightly. It was true that Rangiku's superiority in this regard was universal to just about everyone under the sun. But that didn't change the fact that it made Rukia feel self-conscious.

'The captain is mad at me for not getting paperwork done on time.' said Matsumoto sadly as she stretched. 'So he's sending me to hunt hollows in this town. Why are you out here?'

'I'm looking for the source of some strange spiritual pressure sources.' said Rukia. 'They keep on appearing in and out throughout the town. Then they disappear before the department of research and development can get a lock on one. They're similar to a hollow, but not quite the same and the soul society is getting concerned.' She sighed. 'I should probably get back to it.'

'Well have fun with that, I guess.' said Rangiku. 'I'm going to go meet up with Orihime. That girl is always in a hospitable mood, after all. Feel free to drop by; we'd love your company.'

'I'm sure you would.' said Rukia, not bothering to bring up that Rangiku had no formal invitation. She was, for all intents and purposes, free loading. It would be a waste of her breath anyway.

They parted ways, and Rukia made her way after the power. As it led her onwards, she found herself stalking deeper into back alleys. She was soon in the less safe parts of Karakura Town. Of course, none of the gangs here could pose a threat to her, even if they could see her. Yet it occurred to her that this creature was sticking around much longer than had been in the report. It had stopped moving too. Wondering if she was walking into a trap, Rukia rounded the corner and saw-

Nothing.

Rukia paused, perplexed, and scanned the alleyway for any sign of the beast. The alley was empty, save for a few stains on the walls. Even so, she could pick up an odd scent which filled her nostrils. It was irritating her somehow, and she fidgeted. 'I can't sense it anymore.' she reflected out loud, lowering her sword. 'Where could it have gone?'

She walked further down the alley.

Above Rukia, the beast she was seeking looked down upon her from the top of the building. It was a writhing mass of many tentacles and a very simple creature. It had been born of a single desire. To find a host, and enslave young maidens. The mind directing it indicated that Rukia Kuchiki was a perfect starting place. Rangiku had been considered, but Kuchiki had the greater potential. It had begun its plans by unleashing pheromones into the air that Rukia Kuchiki was breathing in.

Even now the petite soul reaper was beginning to fidget as the pheromones began to take effect.

Was it just Rukia, or was an odd heat coming into being between her legs? The air around her also seemed quite a bit hotter than it was a few minutes ago. She blinked her eyes to try and focus before she caught sight of movement above her. Looking up, she raised her sword to a guard position, feeling a sense of anticipation. She took a deep breath. This might be it.

'Whose there?!' she called up. 'Show yourself!'

A sudden clattering noise to her left drew her attention. She whirled around, sword brought into a stance. Yet all she saw was stray can being blown around by the wind. Out of the corner of her eye, she detected movement. Turning around she saw a mass of tentacles descended towards her. Rukia brought up her sword, but too late, and the creature hit her face. Its tentacles reached around her head, pulling itself tighter around her face. She fell back against the ground. She let go of her sword, and she reached clutching at it with her hands. She wanted to scream as the beast sent its tentacles down her throat. As she struggled in vain, she felt a cold liquid being poured down her throat. Then everything went dark.

When Rukia came to, she felt a pair of hot lips upon her own, and a long tongue exploring her mouth. Two hands were gripping her breasts through her robe and messaging them. Two legs were wrapped around her waist. The eyes she was looking into were violet and she could see herself within them. Bringing up her hands, Rukia pressed against the chest of her assailant. She found herself accidentally groping a pair of breasts her own size. Swallowing her dignity, Rukia shoved hard, trying to get her off her. Eventually whoever it was unwrapped their legs and leaped away. They backflipped several times before landing gracefully in front of her.

The women was her. Down to the tiniest detail, they were the same person. Their eyes met, and a crooked smile came to the woman's face. Then the world shifted, as Rukia suddenly found herself standing upon a frozen lake, with a snow shore. Mist surrounded her on all sides, and out of that mist came Sode No Shirayuki.

The tall, elegant woman had hair as white as snow and ample curves {though not quite as ample as Rangiku's}. She held in one hand a sword. She represented everything Rukia wanted to be, yet now she had a vacant expression. Her eyes were empty.

'Sode No Shirayuki, what is going on here?' asked Rukia. 'Who was that?'

'She and you are one,' said Sode No Shirayuki in a dead tone as she drifted forward, 'she is who you will become. The creature that assaulted you has entered your inner world. You must submit to it.'

'What are you talking about-' began Rukia.

At that moment the ice beneath their feet shattered. Out of the freezing water came tentacles which seized both Rukia and Sode No Shirayuki. The two of them were dragged down into the water, feeling the tendrils drop them. Rukia struggled, while Sode No Shirayuki remained still and silent. It was as if all the life had gone out of here. As they were dragged deeper and deeper into the water, they suddenly came before Rukia's other self. She was standing at the bottom of the lake. Her arms were put forward and her hands had transformed into the tentacles.

'You're finally awake.' said the other Rukia. 'I'm glad; I was getting tired of playing with just your zanpakto.'

'Who are you?!' shouted Rukia. 'What have you done with Sode No Shuryuki?!'

'Nothing that I'm not going to do to you, don't worry.' said the other Rukia, 'now let's begin.'

Rukia became aware that the tentacles were beginning to slip into her clothes. She struggled all the harder as they climbed up her legs and began to poke around in her nether regions. At the same time, others slipped down her shirt, beginning to wrap around her breasts and fondle them. Those on her arms reached into her sleeves and wrapped round her waist. Then they reached lower to fondle her buttocks. Beside her, she could see Sode No Shirayuki suffering a similar fate with a smile of contentment.

'Get off me!' Rukia cried. 'Let me go!'

Rukia's other self smiled. Suddenly the tentacles lost all restraint. Gripping her clothes, they tore them off of Soul Reaper and Zanpakto. That left them clad onto in their underwear, which suffered a similar fate moments later. Rukia screamed as a thick tentacle plunged into her. Her scream was cut off as another drove itself down her throat. Her eyes widened in horror as the tentacles shoved themselves up her rear. Those that remained began to grope her breasts and butt.

The tentacles bounced them both back and forth mercilessly. A horrified blush of humiliation came over Rukia's features as she found herself enjoying it. It seemed as though with every passing moment her body became more and more sensitive. She tried to fight it, tried to break free, to avoid the realization of how much pleasure she was feeling.

Rukia failed, and a low moan echoed from her mouth as the tentacles forced her legs up so that her ankles were by her ears. More tentacles grew from the arms of her other self — these ones sporting what looked like suction cups with long tongues within them.

The suction cups were applied to their breasts, and Rukia's moaning increased in volume. She felt the tongues entered her nipples. The sheer mind-numbing pleasure was preventing Rukia from mounting any resistance. She realized that if she didn't distract herself from what was happening she would lose her mind. Her other self seemed to sense this and removed the tentacle from her mouth. Rukia gasped for air, staring at her. 'Who… who are… ugh… who are you?!'

'I'm you, fool!' snapped the lookalike. 'Or I'm going to be. I'm the manifestation of the tentacles effect on your mind. Their changing you to be the perfect host. You can't hear my name just yet, of course, but by the time I'm done with you, you'll both be moaning it.'

Rukia opened her mouth to speak defiance, but before she could the tentacle slid back in. They seemed to swell even larger. The soul reapers pupils became tiny as her eyes became as wide as saucers from what happened next. The tentacles within her mouth, cunt, and ass swelled up to be far thicker. Soon they were more than three times their original girth. She felt as though she would break in half, and yet the feeling was addicting. She knew it was wrong, and yet the more she had, the more she needed!

'I can hardly think like this…' thought Rukia. 'The sensation, the pleasure… I can't get away from it.' She winced as she felt the tentacles go even deeper into her body. The pleasure was getting to her. 'This… this spirit is supposed to be a part of me. If I learn its name I…'

The tentacle spirit's face was inches away from her. 'Can control me?' asked the tentacle spirit with a smile, as a tendril caressed her face. 'Afraid not, Rukia, I'm not like a zanpakto. They are god given spirits here to help you and need you to grow closer to them so you can speak their name. I'm as much part of the tentacle beast as I am of you. I'm a bridge between its instincts and your consciousness, made to ease you into submission.

'What's happening here is symbolic of the alterations being made to your body. It's useless to struggle against it, you are wasting your energy.'

Once Rukia has said those exact words to Ichigo Kurosaki, and she had been dead wrong. She renewed her struggling as she tried to break free, yet the tentacles gripped her all the harder. Yet as she struggled, she found something deep within her emerging. It was a disturbing enjoyment of her circumstances beyond mere physical pleasure. An appreciation of the helplessness which beset her. Rukia fought against these feelings as the spirit pressed their bodies together.

'Let me put it in terms you might understand better.' said the tentacle spirit. 'In order to get your zanpakto to give you its power you have to force it to submit. With me it's the other way around. Speaking of which, the first of the alterations should be kicking in now.'

Rukia's senses had been raised to enormous heights over the past few minutes. She shuddered with the pleasure which coursed through her spirit. Yet though she wanted to more than anything, she did not cum. Instead, she was stuck languishing in place, unable to find release. As she struggled to free her hands, she found some words coming to her lips. The tentacle removed itself from her mouth once again. 'W-what have you done to me?'

The spirit sighed. 'Well not the reaction I was hoping for, but I can wait. I increased your bodies sensitivity.' She reached forward and fondled Rukia's thigh. Rukia howled in pleasure. 'Now you can't stand the slightest the slightest touch. But I also am preventing you from reaching orgasm. I'd hate to reward disobedience.'

'I am not your pet!' screamed Rukia, hauling and moaning from the sensation.

'Oh but you are,' said the tentacle, 'and once I've taken over, you won't even be that. You'll be my zanpakto alongside your dear Sode No Shirayuki. Your personality and thoughts will still be there, but I'll be the one making the decisions. You'll just be along for the ride. And believe me, you'll be enjoying yourself the whole time.'

'I… I will never submit to you!' said Rukia, as the words screamed in her mind. 'Never!'

'It's only a matter of time now,' said the tentacle spirit, 'like a zanpakto you can't hope to take over for yourself. Just resist my attempts to tame you. All I have to do is keep pushing you, and sooner or later you'll say my name. And once that happens, you are mine.'

Rukia moaned and moaned as the tentacles continued their work. She could feel her mind little by little being subverted. She heard the words screaming inside her to be unleashed. In mere moments she knew she would yield and say those words which result in her subjugation. Across from her she saw Sode Ni Shiryuki in a similar situation and felt sympathy for her. The zanpakto was the manifestation of her soul, her hopes dreams and desires. Maybe… maybe if they worked together, they could break free. 'Sode No… AH! Sode No Shirayuki! Help me please!'

The tentacles were removed from Sode No Shirayuki's mouth. The white-haired Zanpakto stared at her mistress, adoration in her eyes. 'Please Rukia… I can't stand it anymore. Let me cum. Say her name.'

Rukia reeled as the final betrayal of her own soul gripped her. Her resistance quivering, the tentacles intensified their work. Rukia and Sode No Shirayuki were drawn up before the tentacle spirit in a spread eagle position. They only needed one more shove.

'You both know what you want now,' said the tentacle gently. Then she kissed Sode No Shirayuki on the lips, before moving to Rukia and doing the same to her. 'Now shout out my name!'

It was the final shove into oblivion which Rukia and Sode No Shirayuki had been waiting for. 'SHOKUSHU SUREBU!' They screamed in unison.

As soon as they said it, they came. They came, and came and then they came some more. Their simultaneous screams echoing throughout the inner world. It entwined into a single sound the shattered the ice above their heads, as the snowy shore began to melt. Around them, all of Rukia's inner world became liquid. It swirled round into a vortex of water as they endless screaming continued. Rukia's other looked up and opened her mouth as the water began to pour down her throat. On and on it came, spilling into her as Rukia and her Zanpakto's screams continued without end. Finally, there was only darkness around them. Rukia's entire inner world had been consumed by the tentacle spirit. As Rukia and her Zanpakto's screams died down, their eyes dimmed. Happy smiles came onto their expressions as they fell into mindlessness. Finally finished they collapsed onto the ground.

The tentacles which had held them retracted back into Shokushu Surebu's wrists. Soon they transformed back into elegant hands. Her white garments changed shape and color, to become the garb of a soul reaper. She admired her garments in satisfaction.

'This is a great new look.' said Shokushu Surebu. 'Then again, it is only appropriate.'

There was a long, exhausted silence.

After a moment Rukia and Sode No Shirayuki stood up again. They stood before Shokushu Surebu with the same dim smiles. Little by little the light returned to their eyes, as they looked at themselves. The two of them were now clad in altered versions of her Sode No Shirayuki's old garments. Their toned midriffs were bared. Her neckline plunged down to reveal the sides and tops of her breasts. Her skirt was now cut so that it showed off both her thighs.

'W-what have you done to me?' Rukia asked. 'Why do I feel this way, Shokushu?' Her tone was almost childlike.

'I thought I explained it well last time, Rukia,' said Shokushu Surebu 'I'm the one in command now. This inner world is now mine, not yours. You and Sode No Shiryuki now exist within it to serve me.' Her expression became thoughtful. 'In fact, now that I think about it, I'm Rukia now. Which means that the name you screamed before wasn't mine. It was your own.

'Are you alright with that, Shokushu Surebu?' She cupped her by the cheek. Rukia realized that she was now looking through the eyes of her other self. No, her other self was her now.

'Of course mistress.' said the renamed Shokushu Surebu, before pausing. 'I… I mean I have some doubts about all this, but I'm here to help you after all.'

The new Rukia smiled. 'Good, I knew I could count on you. Now, I need to return to the outside world to begin to set in motion our plans.'

'If you need them, my powers are yours to command.' said Sode No Shiryuki.

'And if you need to talk to someone,' said Shokushu. 'I'm here.'

'Thank you both.' said Rukia. 'Have fun.'

As Rukia departed her inner world, Shokushu Surebu and Sode No Shirayuki turned to each other. A sudden lust came into their eyes as they clasped their hands. They pressed their breasts together. Reaching forward with one leg, they ground their knees against each other. Their lips drew nearer. Before long, Sode No Shirayuki was pushed down onto the ground by Shokushu Surebu. They began a passionate kiss.

And as they did so, the new inner world began to take shape.

What had seemed to take hours within her inner world had in actuality taken only a few minutes. As soon as Rukia hit the ground, the tentacle beast increased its grip on her, its limbs binding her arms and legs. Rukia struggled against it for a few moments but in vain. Finally, Rukia went slack, and the tentacle beast began to slink down her throat. Little by little its body compressed itself down to a size where it could fit between her jaws. Her eyes stared up at the sky, empty. Finally, the creature had almost forced itself into her. Only a few tentacles remaining outside of her. As it made it's way deeper into her body, the tentacles were pulled into her, and Rukia's mouth closed.

For a moment nothing happened. Within the tentacles merged into her body, becoming one entity with her. They changed her personality and powers to suit their designs. Rukia's eyes opened, and she smiled. Rising up, she picked up Sode No Shirayuki and sheathed her. 'Well that was an adventure,' she said, looking at her hands and opening and closing them. In her mind, she could feel a background grid of endless pleasure. It was going on between her former self, and Sode No Shirayuki, and it was quite pleasant. 'Now what should I do next?'

Mentally she scanned through a list of all the beautiful women she knew and had access to. It was quite extensive, and she knew now why the tentacles had chosen her. She looked up, her memories giving her the names of her first victims. 'It's time I visited Orihime. It's been a while since I dropped by.' Her smile became hungry. 'And Rangiku will be there too.'

Authors Note:

So here we have the long-awaited return of Tentacle Girl Rukia.

Ever since I reposted my smut fics, everyone has been asking for this one. So here it is, newly edited for better or worse.

I'm posting this now because I only do reposts when I can't think of anything new to put up. Today is one such day. Plus, as an older work, Tentacle Girl Rukia requires a lot of effort to fix.
