Naruto and his team had received their first C-rank mission from the Sandaime Hokage, Sarutobi Hiruzen. They faced off against the Demon Brothers of the Mist and then against Zabuza.

Kakashi who fought Zabuza was caught by the missing nin in a Water Prison Jutsu till Naruto and Sasuke saved him using their combined efforts and Naruto's strategy.

Kakashi then continued fighting against Zabuza and had the upper hand till an Oinin suddenly appeared and shot senbon on Zabuza's neck before carrying him away.

Naruto and his teammates took Kakashi who had collapsed to Tazuna's house. Kakashi told them about the Oinin being a possible ally of Zabuza and started training the Genin on tree-walking. Sakura with her perfect chakra control learnt the exercise her first try. Naruto and Sasuke took a while to learn the exercise. Since then however, Kakashi focused only on training Sasuke ignoring both Naruto and Sakura. While Sakura didn't mind, it didn't sit well with Naruto.

After Sakura and Kakashi ignored his rants, Naruto had an argument with Inari, Tazuna's grandson and stormed out of the house.

Naruto ran towards the forest to train himself. After exhausting himself, Naruto collapsed. An hour later, someone shook Naruto awake. Naruto woke up to see the most beautiful face he had ever seen glowing in the moonlight. It was a girl a few years older than him and atleast a head taller, who woke him up.

The two of them spoke for a while as Naruto opened his heart out to her and told her about how his sensei and teammates hated him and ignored him. The young girl, Haku couldn't help but see herself in the young boy, who desperately wanted to be loved.

"Come with me. I'll take you to a warmer place. It is quite cold outside and based on what you told me about your teammates and the family you are guarding, they must have locked their doors by now, since it is quite late." Haku said to the young blond.

Naruto tried to get up, but he had worked himself into exhaustion and collapsed as soon as he stood up. Haku gently lifted Naruto bridal-style and started walking. Naruto who was a little embarrassed at being carried by a girl said, "Wow, you are quite strong!"
Haku smiled and only embarrassed him further as she said, "Actually you are pretty light. Carrying you won't be a problem at all. You are in fact quite small and light for your age."

To prove her point, Haku bounced him a little on her arms as she walked towards a small cottage while carrying Naruto in her arms. Little did Naruto know, that the person carrying him had previously carried off Zabuza who was several times heavier than him.

Haku decided not to carry Naruto to the house where she was treating Zabuza. She instead carried him to an abandoned cottage, which was among the several cottages that had been abandoned because of Gato.

Haku carried Naruto the bedroom and dropped him on the bed. She then prepared some dinner and fed Naruto, who regained his energy thanks to his tenant and the nutrition.

Naruto then asked as he watched Haku wash the plates while sitting on the bed, "Why did you bring me here? Why are you treating me so nicely?"

Haku who had just finished washing the last plate removed her gloves, crawled to the bed and got very close to him as she said, "I saw the same pain in your eyes that I once had. I now want to take it away."

Naruto was a little scared now, but for some reason he couldn't move his body. He could only watch as Haku came closer and closer till their lips latched on to one another.

'Oh my Kami, her lips are so soft' Naruto thought as he subconsciously wrapped his arms around Haku's neck and pulled her closer. Haku licked the boy's bottom lip requesting entrance which Naruto willingly gave. Soon their tongues were wrestling each other, a battle which Haku won. They continued for what seemed like hours. Soon Naruto began moaning and then all of a sudden, Haku thrust her hips forward, grinding into Naruto's body. Naruto's eyes widened as he broke the kiss and yelled, "YOU'RE A GUY!"

Haku sighed as she said, "No Naruto-kun, I'm not a guy. I'm a girl with certain guy parts. I'm what you call a futanari. Is that gonna be a problem?"
Naruto argued in his head for a while before dropping it and continued to kiss her. Haku slowly grabbed the hem of the boy's jacket, lifting it over his head. Haku could see that the boy was suffering from mal-nutrition but had somehow built some muscle through excessive training. After removing his mesh top, Haku began massaging his abs while kissing his neck.

Haku then pulled the sash on her kimono, letting it drop leaving her with bandages covering her C-cup breasts and a white loin cloth that covered her crotch. Seeing Haku in just bandages and loin cloth got Naruto excited and hard. Seeing the bulge in his pants, Haku licked her lips before removing both his pants and underwear in one swift motion leaving Naruto completely naked. Haku stared at Naruto's five and a half inch dick thinking, 'Not too bad for a twelve year old. Should grow atleast another 2 to 3 inches in a couple of years.'

Naruto tried to remove Haku's bandages and expose her breasts, but hesitated since he hadn't done it before and the last time he accidently touched a girl's breasts, he got the living daylights punched off him. Haku seeing Naruto's predicament removed her bandages and her lion cloth exposing her C-cup breasts, her 10 inch futa dick and her pink pussy. Naruto seeing her much larger dick asked, "Can you impregnate girls with that?"
"No. Even we futa produce sperm have low mortality and hence cannot impregnate anyone. Most futa Kunoichi generally cast a Genjutsu over their penis. Guys during sex, tend to not notice the Genjutsu. But I wanted you to see everything." Haku replied as she put her dick in Naruto's mouth.

Naruto had a hard time putting the ten inch cock in his mouth but with Haku forcing it into him, he had no choice but to comply since she was stronger than him. Haku soon began to throat fuck Naruto holding him in place with one of her hands. Naruto despite his initial discomfort soon began getting into the rhythm and started enjoying it. Soon Haku came inside Naruto's mouth. Naruto took his time to taste and relish the futa cum. 'It's quite delicious. Tastes better than sake atleast.' Naruto thought. Naruto hated sake since he tasted it for the first time as a kid, when some drunk forced it down his throat.

Haku kissed Naruto and using her tongue to probe inside Naruto's mouth, she managed to get a taste of her own seed.

Haku then pushed Naruto onto his back and got on top of him. She placed his cock at the entrance of her pussy as she asked, "Naruto-kun, are you ready to lose your virginity and take mine?"

Seeing Naruto nod, Haku plunged her pussy onto Naruto's cock while bouncing up and down on it. She then moved forwards and began licking the younger blond's nipples.

Soon enough both came at the same time inside Haku's pussy. Haku also came on Naruto's stomach through her dick. She then licked her own sperm as she cleaned Naruto's stomach. Both of them then shared a passionate kiss before laying on the bed for a while after taking each other's virginity while recalling the experience in their heads.

After a few minutes, Haku got up and went to the bathroom. She came back with a lotion before saying, "Naruto-kun, you've taken my virginity and I've taken yours. You have experienced what it is like to be with a woman. Now you'll experience what it is like to be with a futa."

Haku rolled Naruto over onto his stomach thereby exposing his ass. She then applied the lotion on her fingers before moving them slowly over his butt-crack. Naruto tensed upon feeling Haku's fingers on his butt-crack.

"Just relax!" Haku said in a calm voice before plunging a finger through the blond's asshole. Naruto tensed up for a while, till Haku's finger soon hit his prostate, after which he relaxed. Naruto's dick though had hardened and was lying flat on the mattress. Haku seeing Naruto relax soon plunged a second finger into Naruto's asshole. She then began moving her two fingers in and out of Naruto's asshole and Naruto was producing a moaning sound.

Haku then removed her fingers as Naruto groaned at not having anything in his asshole anymore. She then went to the edge of the bed and sat with her feet dangling an inch of the floor. She then turned to Naruto and patted her lap telling him, "Come and sit over here, Narujto-kun if you want to enjoy more."

Naruto got up and without the slightest bit of hesitation, sat on Haku's lap. Haku pulled Naruto off her before repositioning him so that her dick would be in line with his asshole. She then pulled Naruto onto her lap, plunging her dick into Naruto's asshole and hitting his prostate in one swift motion. She then pulled up Naruto's legs so that his knees were on either side of his head and only a portion of his butt was in contact with her lap. Naruto could feel her breasts against his back as she suddenly stood up, carrying him with her. Her arms wrapped around him as he was in an uncomfortable position. He could feel her breath on his ears as she moved him towards a mirror and said, "Watch as I take your anal virginity."

Haku then began to hump Naruto up and down vertically on her dick while holding his weight up within her long and slender arms. Naruto despite his initial discomfort soon began to enjoy it. Haku soon came within Naruto's asshole while Naruto came on to the mirror and the floor. She then pulled her dick out of his asshole and dropped him on the floor before asking, "How was it?"

Naruto tried standing up and noticed futa cum dripping out of his asshole through the mirror as he answered, "It was great. I've never felt so good in my entire life."

"Then are you ready for round two?" Haku asked with an evil smirk.

Naruto nodded without the slightest bit of hesitation as Haku carried Naruto up again, this time Naruto was facing Haku with his legs wrapped around her hips. Haku then spanked Naruto's ass lightly before pulling it up. She then inserted her cock into Naruto asshole again and began fucking him.

Fifteen minutes later both were spent with Naruto's ass filled with Haku's futa cum. Both were lying on the bed, with Naruto on top of Haku as Naruto asked, "You are the fake Oinin who saved Zabuza right?"

Haku tensed a bit before asking, "What gave me away?"

"Your strength, stamina and knowledge about futa Kunoichi using Genjutsu. You are way stronger than me. I know that. I may not be that strong, but no civilian can be as strong as you." Naruto replied before asking, "Why do you work for Zabuza? He is working for Gatou who is a bad person. I know that you are a good person."

"Remember when I said 'when you have something important to protect, that's when you truly become strong' and asked you if you have a 'precious person'?" Haku asked. When Naruto nodded she continued, "Zabuza-sama is my precious person."

Haku then explained to Naruto her entire story and the blood-line purges of Kiri and Zabuza's dream of over-throwing the Mizukage. After hearing her story, Naruto and Haku went to sleep putting all their troubles aside.

The next day, Haku woke up early and decided to go check on Zabuza. When she entered, Zabuza said, "I saw you with the blond kid from Kakashi's squad yesterday. Haku, right now as you are, I cannot ask you to be a part of this mission. I see you as my own son, Haku. If there is going to be any fighting, I want you away from it. Maybe you should go with them to Konoha. I heard that they worship blood-lines there. Now go! I can take care of myself, my daughter."

Haku nodded with tear filled eyes before running back to her cottage where Naruto had just woken up. She told him what Zabuza had said before kissing him square in the lips.

Haku then began training Naruto herself. Using some chakra paper, she found out that Naruto had an affinity for Fuuton. Since her Hyouton was a combination of Fuuton and Suiton, she began his Fuuton training. He spent the rest of the week with Haku training and having sex with her.

He sent a clone who gave a message to Kakashi saying that he was training on his own and didn't want anyone bothering him. Sakura in agitation yelled, "As if someone like you can become strong or train on your own!" before punching the clone.

Naruto received his clone's memories and spoke to Haku about it. Haku seeing how memory is transferred upon dispelling of the kage-bunshin came up with a training program that involved several clones training at once while one of them had sex with her. Soon by the end of two weeks, Naruto managed to learn two Fuuton jutsus. Haku then asked him to find his team, while she checked on Gato.

When Naruto entered Tazuna's house, he noticed two bandits holding Tsunami hostage while preparing to kill Inari. He killed both the bandits and saved the kid and his mother, who thanked the blond for saving their lives.

Upon reaching the bridge, he noticed Kakashi fighting Zabuza. When Zabuza saw Naruto, he asked him about Haku. Just then Haku appeared on the bridge and told Zabuza that Gato was planning on betraying Zabuza. Zabuza stopped fighting and waited for Gato to appear, after which he let loose on them and killed every single bandit he hired before killing off Gato as well.

After a tearful goodbye, Zabuza parted with Haku as he left for Kiri while she joined Naruto and began walking towards Konoha.
