(Soul Society)

Retsu Unohana or rather her true name Yachiru Unohana was laid on a bed, her wounds nursed, and everything having been treated.

"I thought I trained a warrior, not a coward." a male voice said nearby on a porch.

"Master." Unohana said in both respect and recognition seeing a man who seemed about as old as Ichigo Kurosaki, this man was the man who had trained her to wield a blade, Naruto Namikaze.

"I told you to fight and die with honor if that was your wish, not surrender." Naruto said to her "I turned a blind eye as the Soul Society was trash when I first came here and you killed criminals, then you became a healer, a wonderful one at that." he said as he recognized and saw her talent.

Unohana was silent as she was scolded, she could not deny this.

"You could've nurtured them, you know, Byakuya and Ichigo." Naruto said as it was as if he was seeing his own past, Byakuya needed guidance to see that the law could be challenged and Ichigo reminded him a lot of himself, someone who developed when right in the thick of it all.

Unohana knew those two needed guidance, she took a real shine to Ichigo as he reminded her much of Kenpachi, but Ichigo sought combat for a more noble reason, it honestly reminded her of Naruto a lot of the time "Where are we?" she asked him.

"Couple hundred miles from the 99th district, I told you before soul reapers are creatures of habit and they make little to no progress with all the time they have." Naruto said to her.

Unohana had to agree as looking around, she saw a garden and field of plants that could feed a large district and it was all done by one man.

Unohana was fully healed and sparring against her master, sparring being the polite term as in reality he was bored while she gave him everything she had.

"Instinct or mind, both can be countered, but when your body moves in unison it's not wasting a single movement you'll fight better." Naruto said to her.

Unohana hated that as it was the one lesson she never got.

(1 month later)

Unohana was bored out of her mind, the Soul Society was not an option as she felt that chapter of her life was done with, there were no enemies to combat, and she had so few friends to talk to.

In all honesty, she missed the women's association as while some were shy some were very bold, she missed that, she missed being able to tease some of them mostly Isane, but she mostly missed sex.

There were a handful of men she had slept with, but the number of women was long, she had women begging her for pleasure and release, Isane being the biggest of all of them, the girl was eccentric for lack of a better word, but she was a good lay, which was why she kept her by her side whenever she was bored or wanted a quickie she was near, but in the end Naruto her own master was the greatest she ever had, when he trained her she was treated as a warrior not just a woman, but in bed he was her master in every conceivable way, he had full control, it turned her on greatly, he made her his woman whenever they were alone never giving her an inch.

(few days later)

Unohana was silent looking down at a familiar face, Nel Tu "Do you pick up strays wherever you go?" she asked him curiously.

"I do given I find you." Naruto said to her "Also she found me." he said still not sure how the hell she did as he was well aware this child was also an adult.

Unohana at least had something to do as Nel bothered Naruto, it was honestly hilarious.

(next day)

"You've become more honest." Naruto said simply as he noticed it when Unohana talked with Nel, she wasn't lying when she became 'Retsu', she just buried most of her blood thirst, the reason she sought out criminals was more because she wanted to stop bad things happening in the soul society, she had watched children beaten just as she was, when he first met her, she was dying, she had been beaten for the soul reason of just being an easy target, she had her scars much similar to his own, but they still haunted her.

Naruto connected with Unohana in a way few could understand, they knew what it was like to suffer, and they bonded and connected over that pain and even healed some of the deeper wounds they had.

Naruto was not afraid to admit after a long period he fell for her going beyond the master-student relationship, but Unohana was scared, something he should have realized, love was something they never received in great abundance or in total honesty, he should've known she would've run.

Unohana was silent as that was a compliment from him or as close as he gave whenever training, the two continued to fight at an inhuman pace.

(1 hour later)

Unohana disliked kido aside from healing kido, it always felt less personal whenever using a spell to attack, but her master's technique, the rasengan, was a work of art, the power, concentration, the very spirit it took to wield such a dangerous and deadly technique was inspiring, he made sure to teach her this technique, and while never having used it, it was still an amazing technique.

Unohana evaluated her life, she was a warrior, a healer, a captain, a leader, and a soldier, but in the end she still felt inconplete even after all she had done to atone for her many mistakes, but the one mistake that left her empty was leaving her master, she left as he saw hope, he was a man who she honestly thought she'd ruin, he saw the good and she saw the bad, he wanted to build his own life and start a family, but she felt unworthy given her violent past and how she didn't feel like she could be the maternal type, in many ways it probably explained why she had a soft spot for children.

'Am I going to make the same mistake again?' Unohana thought to herself as she ran last time, the first time she ran away from something, she placed a hand over her womb and thought about a child of her own, one belonging to her and the man she called master.

(later that day)

Unohana felt the hot steam from the bathhouse her master had, and she felt her heart beating a mile a minute 'The only man that can make me quiver.' she thought meaning that both literally and sexually.

Unohana entered and saw Naruto enjoying his bath, she bit her lip as she saw Naruto's body, he had no scars, and it was not for a lack of trying as he explained he healed fast, while she appreciated scars having some herself, but the fact Naruto had none excited her greatly, she loved the idea of just someday being able to cut him or at the very least leave her mark on his body.

"If you are gonna wreck my bath again there will be consequences." Naruto said not even needing to look her way.

Unohana rubbed her thighs together as she remembered that day, she had snuck up on Naruto or at least attempted to do so and in the process destroyed a wall and broke the ground of the bath, she was punished with a hard spanking, no one paid attention to her ass as much as her heavenly bountiful tits, it was nice to get appreciated everywhere on her body, she entered the water having discarded her towel and knelt before him her head still above water and her massive tits floating to the top.

Unohana smiled feeling something strong hit the bottom of her breasts 'Stronger than steel.' she thought to herself feeling it between her tits, she licked the tip lovingly, but moaned as Naruto grabbed the back of her head making her take more.

"It has been a long time Unohana, I need to retrain your body." Naruto said to her neutrally.

Unohana quivered at that thought, he separated her mouth from his dick and brought her deeper into the bath, he brought her to the end and looked at her expectantly.

Unohana smiled, she bent forward, her top half resting on the edge of the outside of the bath and her holes very exposed, she felt Naruto trace her slit and then rub the rim of her asshole, she shook her ass eager to have him inside her and to stretch her out.

"Still the same slut when I was training you." Naruto said slapping her ass.

Unohana let out a loud moan "No man has touched me master." she said quickly, she knew Naruto ruined her for any other man other than him "But I have delighted in other women." she said as she licked her lips as during her time as a captain she often thought of bringing women to her master, Rangiku and Isane chief amongst them as Rangiku talked a big game, but she had no love life or even a sex life, Isane was simple, she was her toy for years.

Naruto didn't care as he thrusted into her pussy making her scream.

'I'm so full.' Unohana thought feeling him reshape her pussy from it's unuse, she jolted forward as he begun ramming into her womb 'He won't stop till he's inside.' she thought moaning with glee as that was the only place her master released his seed, when he was in the deepest parts of her, she screamed at the top of her lungs when she felt him reach inside and started hitting the back of her womb "You want children, then cum stuff my womb master, mark like you once did, and I shall carry your legacy!" she said lustfully wanting to fell his hot semen flood and paint her insides, she soon got her wish as his thrusts got more aggressive and she felt him twitch inside her and screamed again, she twitched feeling her insides fill 'I forgot how much he let out~.' she thought feeling her stomach expand a bit making her look a few months pregnant..

Naruto wasn't finished with Unohana, he grabbed her by her thighs and lifted her up, placing her in a full nelson, his dick never leaving her and he resumed his thrusts.

Unohana felt her eyes roll upward and her legs felt like jelly, her master was making all the cum trapped inside her slosh around.

"Your pregnancy will not be left to chance." Naruto said to her.

Unohana felt her mind slowly leave her as this went on, her stomach filling with each load he let inside her.

(next morning)

Unohana felt tired and dirty, even while in the bath, Naruto had fucked her to completion, she still felt his cum dripping down her legs ruining her sheets, but couldn't help but savor the erotic smell, when he released her, pulling his dick away, she looked as if she was 9 months pregnant, it was rougher and harsher than she had ever been treated 'I wasn't treated with the intent to be bred before.' she thought to herself.

Unohana contemplated being a mother, she looked at her tits and thought of them getting bigger and filling with milk and how her hips would grow wider due to her pregnancy.

Unohana left her room, her naked body bare to the world, she saw Naruto making breakfast and approached him lovingly.

"We'll start again after lunch." Naruto said surprising her "One attempt may not be enough." he said to her.

Unohana bit her lip as she was almost positive that one attempt from yesterday was enough to get even the most infertile woman pregnant, but he was planning to put her through more, she was both turned on and excited by the prospect.

(1 week later)

Unohana was sore as each session with Naruto felt like her most intense battle ever, she felt thoroughly fucked, her master never leaving any part of her untouched or unsatisfied, honestly she felt more at peace than she had ever been in her life, today she was able to determine her pregnancy status, it was a simple thing given she had master her spirit energy, was in tune with Minazuki who could monitor any change to her, and her healing mastery, she felt odd creating life instead of taking it as she had done in the past.

When she told Naruto the news she saw true joy in her master, and his gentle touch with her and whenever he placed his hand over her womb, he was anxious to meet their child 'Maybe a life like this won't be so bad.' she thought happily.
