Chapter 1 - Unstoppable Favor
"Did it feel good?" Naruto was nervous. He knew he had done a poor job, again.
"It felt great, sweety. I loved it." Hinata kissed Naruto while caressing his chest. "You don't have to be so self-conscious."
"Right... It's just..." He looked her in the eyes. Hinata stared at him with kindness and love. "...I can tell you didn't finish. I keep failing to make you orgasm. I can't even remember the last time you did."
"Why does that worry you so much?"
"Because I love you, of course! I mean, I always finish." He looked at the condom thrown on the floor. It was filled with Naruto's load. He then looked at his penis going soft. 'Could I just be too small for her? Maybe if I were bigger... Or manlier...'
"Naruto!" She turned his face to look back at her. "It's not you, it's me. I've always been a timid girl... It's hard for me to relax and let loose. Your size is perfectly fine too. Okay? It's not your fault if I've only orgasmed once or twice in our sex life despite your best efforts. I know you are trying, and that is all that matters. And, you know... I masturbate when you're not home, so I can keep myself pleased that way. I love you."
She consoled him for a little longer and they ended up falling asleep.
Naruto continued to think about it.

"Here you go, sir. Let me know once you've signed these papers." One of Naruto's assistants handed him more paperwork. He continued to endure the boring, bureaucratic daily life of being Hokage.
Tired from all his tasks, Naruto took a break and walked around the building. He saw two of Sakura's medical assistants and moved to greet them. However, he stopped before being noticed. They were chatting about something interesting, and he wanted to spy on the conversation.
"Wow, you're so bad, just spilling out her secrets like that!" One of the girls giggled.
"I can't help it! She wouldn't stop telling me about how hung Sasuke was and how good he fucked her! I was getting jealous!"
"Just tell your boyfriend to do better!"
"No way! He'll never live up to her descriptions, I want to find a guy like Sasuke now!"
"You know, she's probably just making it up for bragging rights. I bet he's not even that big."
"Actually…" She got closer and whispered to her friend. Thankfully, Naruto could still hear. "I went to their house one day to deliver some parcels to Sakura and I accidentally caught them in the act."
"Whaaat? Really? How much did you see?"
"I stopped at the door, really nervous. I swear to you, she was wailing like some crazy woman. I knocked on the door and she came up to me with her clothes all messed up, and she was suuuper sweaty! And I accidentally saw him in the back..."
"No way! And...?"
"It. Is. Big. And her face... It looked so..." She paused.
"So what...?"
"So... I don't know how to describe it! Like she was deranged? Or insane? Or in bliss? It was super weird, I had never seen that..."
"But she's so serious all the time! I can't even imagine what that looked like. Hey... I heard she's on a mission trip now. What if we went to hit on him and..."
"Are you nuts?! That's..."
The two girls moved away, still talking and giggling with each other
Naruto's eyes were wide open. 'Sasuke is really big and... Makes Sakura behave weird?!' He was fascinated by what he overheard.
***
Hinata was already asleep. Naruto remained awake, unable to sleep. He sat up and stared at his wife's face. She looked very peaceful and calm. This was her expression nearly all the time. Even during sex, with his best efforts, her face barely inched away from normalcy.
Naruto began to obsessively fantasize. 'What would it look like if her face became all messed up?' His mind went back to the conversation between the two women. 'Sakura with a blissful, bizarre expression... If Hinata had sex with Sasuke... Would the same thing happen to her? Would she show him a face and a side of herself that only he can achieve? Can Hinata even have such a face? What would her moans sound like...?'
He felt his dick getting hard. Naruto jerked off in secret and went back to sleep. He dreamed of all the potential faces of pleasure Hinata could make.
They all felt completely alien to him.
From that day on, a depraved fetish awakened within him.
***
Two months had passed since then. Naruto masturbated to his fantasies every single night since then. Naturally, he never told Hinata. He was afraid of her reaction and felt uncomfortable with it.
As a consequence, his fantasy became stronger with time. It would not go away no matter how much he tried to fight it. His lackluster sexual performance became even worse. He would rather jerk off to his mental images of a fictitious, sexually overjoyed Hinata.
This made him feel more distant from his wife. It brought him feelings of guilt, despite her behavior and bond with him remaining virtually the same.
One day, he learned Sakura was once more going on a mission that would keep her away from the village for several days. Unable to bear his pervertedness any longer, he decided to act on his stupid whims.
He would ask Sasuke to fuck his wife.
***
"I've always known you were pathetic, but this does imply new records." Sasuke looked at Naruto with cynicism. "What even goes on in your head to make a request like that?"
"I know it sounds weird, Sasuke, but you're the only one who can help me!" Naruto had already dropped all pretense of shame. He needed his fantasy to come true.
"Wouldn't it be easier for you to just communicate better with your wife and learn to please her? If you put in enough work..."
"No!" Naruto interrupted Sasuke. His impetus surprised them both. "I can't make it happen. I'm not good enough, but you... I bet you could do it, Sasuke! I've tried my best since forever, but I just can't please her! She insists it's okay, that it's her, but... I know it's me."
There was a long pause between them until Sasuke spoke up. "Why me? I am with Sakura."
"Well, I don't know how Sakura feels, but... I've heard you're big, so maybe you could help break Hinata out of her shell..." He looked away, embarrassed.
"I'm big, huh? Then, are you small?"
"...Yeah."
"How small?" The smugness showed through his voice.
"Ugh..." He did not want to answer, but he needed Sasuke to agree and wanted to avoid conflict. He used his index fingers to demonstrate the length of his erect penis. "This much..."
"No wonder you can't please her. A woman like Hinata needs a proper dick. I understand your problem now." Sasuke paused and studied Naruto's face.
He felt nervous, as if in some sort of job interview. This sort of anxiety was silly for him, considering his role as the most important ninja in the village.
"Do you understand what you're asking of me?"
"Yes."
"Then say it explicitly." Sasuke crossed his arms and leaned back on the chair.
"I am asking you to fuck my wife."
"No, that's not it." Sasuke leaned forward and pierced Naruto's eyes with his stoic gaze. "Naruto, I have an enormous sex drive and a dick that is MUCH bigger than yours. Sakura herself has issues keeping up with me, and you'll have a hard time finding fitter ninjas than her. If I have sex with Hinata, she will change forever. Your wife will no longer be the same woman you know, and you will never be able to take it back. Are you sure you want to do this?"
Naruto's heart sped up a little. Sasuke's tone slightly frightened him. "You don't have to act so grand, Sasuke. It's just sex..."
"No, Naruto." Sasuke put his hands on Naruto's shoulder. His firm grip made Naruto aware of how important this was. "She will never forget what true sex and pleasure feel like. The kind Hinata that you know will think less of you as a man, and she will become completely addicted to my dick. She will continue to love you, but her body will never be yours again." He paused. "Are you sure?"
Naruto's heart was racing, but not due to anxiety. It was due to excitement. He nodded.
"Very well, then. Come with me." Sasuke stood up and walked to his bedroom. Its main feature was a large king-sized bed. "Get in there." Sasuke pointed to a closet.
"What for?"
"I'll show you what you're getting Hinata into if you go ahead with this. I won't hear about any regrets later." Sasuke was very firm with his tone.
"Show me? Then, does that mean..."
"Leave a shadow clone in that closet and go home. Tonight, once I'm done destroying Sakura, it'll undo itself and you'll gain its memory. If you still insist then, I'll transform your wife into a living hole for my use, no refunds allowed."
"Why don't I just stay myself? Then I don't have to wait."
Sasuke smirked. "It's also a test of your patience and willpower. You'll need a lot of it to cope with the feelings you'll get when you realize even a pure girl like Hinata is no different from a sex-addicted prostitute when faced with superior sex.."
"Fine, I accept. But wait, wasn't Sakura on a mission outside the village?"
"Forget that and pay attention. By noon tomorrow, if you don't tell me that you've changed your mind, there will be no going back. You can consider Hinata lost to you, even if you beg me to stop. We'll also establish some ground rules. You'll respect them if you want me to go ahead with this..."
***
Naruto was home, in bed with his wife. She was readying herself to fall asleep.
"What is it, sweety? You're looking at me so much." She noticed his gaze.
"Hm? Oh, no, nothing." He was distracted, thinking of the rules Sasuke imposed on him and anxiously waiting for his shadow clone to dispel itself.
The rules were simple: He could not tell Hinata about his request; He could not, in any way, shape, or form, interfere in Sasuke and Hinata's affair.
'In other words... Hinata is not aware that I want this to happen. Any form of sexual contact between her and Sasuke would be irrefutably cheating. And if she enjoys it more and more and becomes addicted to sex with him, as he said... She's not doing it just to please my fantasy. She'd be a genuine cheater, in her mind.' He looked at the drawer by his bed. 'In there, I put the little sphere he gave me. If it starts lighting red and vibrating, it means he's signaled me that they're having sex and I can come to watch.'
"Hey, Naruto... It's been a while since we've done it. Do you want to try...?"
"Oh, sorry, honey... Not tonight. I'm not really feeling it."
"Oh... Yeah, I get it. Then, good night." She kissed him on the lips and went to sleep.
Naruto felt guilty. He could see the sadness in Hinata's eyes from being rejected. Their sex life had been slowly dying the past few months. However, even if he wanted to have sex with her, his mind would not be engaged.
The only thing he cared about right now was the memories his shadow clone would retrieve. 'Still, something must be wrong. It's already past midnight. He said they would meet at 6 PM. There's no way they are still having sex even now. What's going on-'
It happened right then.
A flood of messy, jumbled-up memories and feelings swarmed his brain.

"Thanks for accepting me the night before I go, Sasuke ♡. Grhlk...! Ghrhl...! Grhngh...!" Sakura was squatting down, fucking her own throat on Sasuke's penis. It was a massive, thick log covered in veins. "Give me a lot of tasty milk tonight, so I do a really good job tomorrow...!"
Sasuke had a grip on her hair. "Don't you feel like a lazy whore when you pretend to go on a mission a day early, just to spend the day getting dicked by me?"
"No...! Ghrngl...! Ghurghl...! You know I can't stop thinking about your cock...! I want you to give me another child...!" Sakura panted, trying to keep her breathing in check. Her pussy was soaked wet, dripping onto her nude thighs. "Please... Please cum inside me today...! Give it to me deep..."
"How typical of you. You've always been very devoted to me, haven't you?"
"That's because I always knew you were a hung stallion... ♡! I want this stallion cock all to myself, forever... ♡!" Sakura ardently licked his shaft up and down. Bubbles of spit coated the area around her lips, but she did not mind it.
Naruto was flabbergasted. He could never have fathomed Sakura to behave even mildly close to this lewdly, nor the fact that Sasuke's penis was this monstrously sized.
Sasuke harshly pulled her up by the hair. "I've already told you that we won't be getting married. You're just the mother of my kids. If I want to, I'll breed as many women as I want."
Sakura giggled at his face. "You always say that, but you're totally in love with me, aren't you? You only sleep with me." She jerked his cock viciously, disregarding his harsh words.
"I won't deny that your pussy is my favorite. There is no reason to waste my time with other cockholes if yours does the best job. Do you know why yours is my favorite?" He turned her around and pushed her against the bed.
She kept her toned ass stuck out to take Sasuke's cock the moment he wanted to enter her, with her C-cup breasts and face staining the bed with sweat. "It's because my pussy's the tightest, wettest, most adaptable hole you've ever had ♡♡! You love my pussy, so you love me ♡♡!"
"That's right." He vigorously molested her asscheeks. "I've roughed up your little wet hole so many times by now that it's been completely reshaped to serve me. My cock perfectly fits in it, all the way to your womb. That makes you happy, since you've basically decided you live to milk me."
"Yeeees ♡♡! This pussy is always available for your private use, whenever, wherever!! Please use it lots and lots and fuck the living shit out of it- NGHHOOOOOOOOOOH ♡♡!"
Sasuke pulled her upper body by the hair while lunging into her pussy at the exact same time. Her body arched while a thick bulge pushed her belly out.
For the next several hours, there was little dialogue between them. Sasuke animalistically and relentlessly brutalized Sakura's hole, thrusting without an ounce of remorse for the physical abuse he was dishing out to her body.
Sakura herself presented no resistance. Her body entered long spasms regularly for the duration of their entire fucking session, showing the power of her orgasms. She constantly moaned and shouted words of self-deprecation. Though Sasuke treated her inhumanly, slapping her ass silly and repeatedly tugging on her hair to the point of causing her pain, Sakura not once told him to stop.
She simply begged him to go harder and faster, more and more. Her body was a tool to milk his cock through the friction of her meaty pussy walls, with her womb as a human-made receptacle for his sperm. No one could deduce Sakura was the one producing the senseless moans that came out of her. She had turned into a different human being.
By the end of their session, Sakura's ass was red. Her chest heaved up and down, while her face was buried against the sheets, borderline unconscious. Loads of cum gushed out of her pussy involuntarily as a natural reaction from her body, which tried to expel the copious amounts of fluid that no womb could possibly hold.
Naruto counted at least 10 ejaculations from Sasuke. From Sakura, he had no number. Both of their bodies were sweaty, and their muscles were pumped-up thanks to the incredible efforts exerted by both in their mission to please each other.
"You're still alive, right?" Sasuke turned her body around, allowing Naruto to see her face.
Her eyes were rolled up, twitching, tongue stuck out.
The mind-numbing ecstasy had made her brain go stupid.
Sakura, the genius, serious, dedicated medical ninja had a look of sheer, plain stupidity on her face. Nobody could say she was anything other than a cock-craving slut at that moment.
"More... Shove it in me more...! I can take more fat, Uchiha cock... ♡♡!" With her hoarse, barely-working voice, she incited Sasuke to use her further.
"No need to ask..." Sasuke glanced at the closet, locking eyes with Naruto. "I think you'll be leaving quite late for your mission tomorrow, Sakura." He plugged her pussy hole in one swift motion, forcing voluminous amounts of semen out of her pussy due to a lack of room.
"HOOOOOOOOOOH ♡♡!!"
The clone was unable to handle it anymore. This was his last memory.
***
"Naruto! What is it?!" Hinata was shaking Naruto, trying to get him to answer.
"Huh?! What?!"
"Your forehead is sweating, and your face...! It's like you froze! I've been trying to get you to speak to me for a minute now! Are you okay?"
"O-oh! Sorry, I was distracted... Thinking about something."
"I see... If you say so..." They stood in silence for a while. "I'll go back to sleep, then."
"Wait!" Naruto grabbed her forearm and looked directly into her eyes. "Hinata, you love me, right?"
"Of course I do."
"Would you ever... Cheat on me?"
She was surprised by his question. "No! Why are you asking me that? I've never...-"
"It's okay, it's okay! I just had a bad dream recently and it stuck in my head. I trust you, of course." Hinata quieted down. "What about just thinking about other guys, like handsome ones. Have you done that before?"
"Handsome? Like Sasuke?" She answered almost immediately.
"Y-yes."
"Of course not, sweety. Never, in a million years, would I ever even think of handsome guys like Sasuke. I love you."
Their interaction soon ended, and they went to sleep.
He intended to let Sasuke go ahead.
