Prohibited Training

At some point between Kakashi training Naruto and Yamato using his wood jutsu to block the fox's chakra so that everything remained controlled, nothing could go wrong – except for what did, what went out of control: Naruto was with two clones, improving, becoming an incredible ninja, when Kakashi, moved, said: "I don't quite know how to say this, Naruto, but I'm starting to like you."

As always, Naruto acted comically because it was easier for him to be a goofball than to take that phrase seriously. He had always admired his sensei, and the more he grew, the more he developed, and the more his body seemed to respond to feelings he kept locked up as part of his inner monster, as if it were the very Fox distorting his mind so that at some point, he would express himself and perhaps release it by mistake.

Cautiously, Kakashi approached, 'trying to explain himself better,' but every step he took, Naruto took three back, pretending it was an affront and that it wasn't the time for something like that. Many times during battles, he felt excitement. Indeed, Naruto had already learned very well to control his chakra, as well as his body, when he realized he was aroused at the wrong times. But also, every time he paid too much attention to silly things, like his sensei walking casually down the street, sometimes without his ninja service clothes, with a book in hand, simply existing and being human. That, for Naruto, was the most exciting thing about Kakashi. Thinking of him not as his sensei but as someone ordinary who might one day reciprocate him.

Going home after training was exhausting. He was sure he was close to something grand, and soon, he could become a ninja the entire village would see as strong enough to be Hokage. That's what he focused on as he returned home, even though Kakashi's words echoed in his mind, and his whole body began to get hot from the adolescent fury of hormones.

Naruto arrived at his house. Empty, smelling of days without being cleaned due to his dedication to fighting. He tried to release energy by cleaning the apartment, even though he was tired from training. After everything was in place, he decided that taking a bath would be great to relax. While under the water, Kakashi's voice echoed in his mind again. Why stay idle? He decided once and for all to release his thoughts and masturbate to satisfy his desire.

But he didn't expect it to end like this... It started in the bathroom, with simple masturbation, Kakashi's voice saying "I'm starting to like you, Naruto," the scent of his sensei, the times he had seen a little more than he should under the ninja clothes, Kakashi's shape... Naruto felt a strong desire to satisfy himself in another way. He blushed, even though he was alone, but precisely because he was alone, he had the courage to go ahead. He got out of the bath, still aroused, and made sure to close his window tightly.

There was a small pile of clothes he would later wash. Naruto molded it into a cylindrical shape. He swallowed hard, closed his eyes, and sat on it. He resumed masturbating and moving atop the positioned pile, thinking of his sensei. At first, he thought it would excite him less, but soon he let go of the shame and rubbed himself fiercely on the bed, imagining being penetrated by his sensei, masturbating more and more, letting out muffled moans to avoid drawing the attention of anyone who might pass by on the street.

When he felt he was about to come, he realized he was saying Kakashi's name, slightly muffled by moans, and hearing his voice say it was what brought him to the peak. He imagined his sensei passing by on the street, entering, catching the scene, coming for everything. Of course, it didn't happen, but his fantasies were wild after having the courage to climb that pile of suspicious clothes.

The next day, he had to overcome the shame of what he had done, as it was his intimacy he would have to live with. He tried not to act weird or give himself away. Early on, he argued with Kakashi, Yamato, and even Granny Tsunade. As he was so close to perfecting himself, the correct thing would be to rest and fully recover his chakra. Kakashi said he would take him to the nearest hot springs, but Naruto said he would stay home. The last thing he wanted was to be near his half-naked sensei at that point. As he left, pretending to be angry, he could still hear an invitation to eat at Ichiraku, but he said he wasn't hungry. He almost had to run home because he wanted, needed to masturbate again after seeing his master. The hot springs invitation had triggered many imaginations, furtive ideas; his body was again on fire.

Naruto's window stayed closed for days. No one saw him leave to eat, but they assumed he was eating ramen at home and getting plenty of sleep. Except, of course, Kakashi, who didn't understand why Naruto suddenly became so elusive. In reality, he imagined it had to do with the declaration he made. As the adult in the situation, he urgently needed to explain himself, especially since Yamato had overheard it. Despite being good friends, it didn't look good and could become a future problem. A rumor about a sensei in love with his student seemed like something out of books, and not the well-regarded kind.

Being a stealthy ninja has its advantages and disadvantages. During his life, Kakashi had already caught people off guard in bathrooms or while attending to their needs and always acted professionally. However, as he approached the second-floor window of Naruto's apartment, he heard muffled moans and his name being called. For a moment, his heart stopped, and he paused his hands that were quickly about to fling open the window. Kakashi moved closer to the slats and observed inside, which wasn't dark, and saw Naruto naked, touching himself, moaning his name, and moving on the bed.

Naruto had lost track of how many days he satisfied his desires locked in his room, like any teenager discovering masturbation. But one day, before he could do anything, someone knocked on his door. There was no problem opening it; after all, he left no traces of his 'crimes.' His apartment had never been so clean.

But he felt a chill down his spine when he found his sensei at the door.

— Naruto, good morning! — said Kakashi, as if nothing was wrong. Naruto swallowed hard.

— Can I train again, sensei?

— Not exactly. But I thought of training that will sharpen your senses and maybe also help you control the fox's chakra.

Naruto became interested, completely dispersing the nervous feeling he had until that moment.

— Really?! I'll just get dressed and...

— No need. — Kakashi interrupted, quickly looking him up and down. — The more comfortable you are, the better.

— Okay... — And then it came back. The nervousness. After agreeing, Naruto followed Kakashi. Inside the village, passing through many familiar streets, without saying a word. He found it strange they weren't going to the same place where he had previously trained with Captain Yamato. — Where are we going, sensei?

— To my house. — said Kakashi without looking back, missing the moment when Naruto almost choked on his saliva and stopped to cough, with his heart in his throat. None of them, Team 7, the students, of Konoha!, had been to Kakashi's house. Bringing someone to his home was extremely intimate for older ninjas. Naruto was simultaneously intrigued and super nervous about seeing his sensei's house. Would he also see Kakashi's face, finally? With so many questions in his head, he didn't even notice when they moved away from the village houses and reached Kakashi's home. A place where he was born and raised, alone, like Naruto.

Pulled from his thoughts, he heard a "welcome" from his master. Naruto took off his sandals and entered the house right after Kakashi, looking around with affection and emotion.

— Wow, Sensei, your house is huge!

— It belonged to my family. It's a bit too big just for me. Since I never have visitors, I don't stay here much...— Kakashi opened one of the windows overlooking the garden. It was a beautiful sunny day, hardly seeming like there was any reason to prepare so much for an imminent war. — You're the first I've brought here, Naruto...

Naruto placed a hand on his chest, and involuntarily his eyes filled with tears. He felt honored and, at the same time, sad that his sensei was such a lonely person. At the same time, it was like he understood him without even having to ask.

Kakashi approached Naruto. — Why are you crying?

— It's nothing, sensei. I'm just happy to be here. I feel important and...

— Loved. — said Kakashi, but Naruto was surprised.

— Cherished... I was going to say cherished...

— Can I trust you, Naruto?— Kakashi said, quickly dissipating the awkward moment he created.

— Of course, Kakashi sensei. Always!

— Close your eyes, and don't open them until I tell you.

Naruto closed his eyes but kept talking, to avoid getting nervous about the sounds he heard of Kakashi moving away and handling things in his house. — You know, sensei, I've trained like this before, closing my eyes to sharpen my senses. I can control my chakra and hear well. I don't know if there will be much to improve if that's the goal.

— Not that I don't trust you, but since you said that, I'll put a blindfold on... Stay calm. — said Kakashi, approaching, and gently placing a blindfold on Naruto.

— Why this, sensei...?

A sound of fabric being lowered, and suddenly Kakashi's voice sounded much louder.

— To remove my mask.

Naruto intended to remove the blindfold immediately, but Kakashi held his hands and spoke so close to Naruto's face that he could now feel his breath and scent.

— Please, Naruto... I'm not ready yet to undress like this in front of you...

— What are you saying, sensei... — Naruto blushed all over, feeling his whole body shiver when Kakashi caressed his hands and guided them. Naruto felt they were now against Kakashi's chest; he felt his sensei's racing heartbeat at his fingertips, even through the shirt. The fabric was thin; he had removed the vest. Naruto sensed a scent, almost like perfume, perhaps from his master's hair. Suddenly, his lips touched something; it was soft, and he didn't pull back. His mind was confused, but he knew that in his hands were Kakashi's hands, and those lips could only also belong to his master.

Naruto felt the kiss and reciprocated. At first, it was a peck, but as he sighed, it became something more. He opened his mouth for a warmer kiss, and his hands were freed, free to caress all of Kakashi's chest. Soon, he felt his waist delicately grabbed, and as the kiss lost its shyness, Kakashi's hands also became more interested in Naruto's body.

The young man didn't know how to respond beyond, even though in his fantasies he had thousands of ways he'd like to act, he hadn't imagined it starting this way. It was something new, and for a moment, he thought he was dreaming, having this moment with his sensei.

Kakashi interrupted the kiss, breathing heavily. — Wait, Naruto...

— Why...?— Kakashi took his hands and kissed them, leaving Naruto shy. Then he lowered them over his body.

— Hold... — said Kakashi. Naruto held his shirt and helped him undress, still blindfolded. He felt his hands being guided again, now lower. Kakashi caressed them while he removed his belt. Naruto felt his hands trembling with nerves and excitement, even not seeing anything; he could feel the pants being removed, the sound of the fabric sliding down Kakashi's body. — Can you see me, Naruto?

— No... Ah! — Naruto was surprised as Kakashi placed his member in his hands, which was hard, pulsating, and warm. For a moment, Naruto stammered, changing his answer: — Y-yes, sensei!

Naruto now breathed deeply, not even knowing what to do with his hands. Soon, he felt Kakashi closing his hands over his and followed his master's orders, who, even without saying anything, knew well how to show what he wanted. Naruto closed his hand around the member and started moving in a way that soon had Kakashi moaning. He felt his master come close to his ear while moaning.

— I want you, Naruto... — he said, and Naruto felt him release his hands. — Don't stop... — Naruto continued the movements as he had learned, while Kakashi kissed his face and neck, sucking, licking, possibly leaving marks.

— Sensei... It's getting very tight... — said Naruto, whose pants no longer accommodated his own hardened member with the situation. He heard Kakashi chuckle softly.

— Okay, Naruto... Then come... — he stopped what he was doing with his hands when his master touched him. Naruto felt his waist embraced, walking carefully through the house, unable to see anything. — Sit...

When Naruto sat, it all happened very quickly. Perhaps because he was a ninja, Kakashi already had his hands prepared for it. But before he realized it, his shirt was lifted over his head, and his pants quickly pulled down. Even blindfolded, Naruto felt embarrassed, defenseless, and for a moment, too exposed. Especially since Kakashi had stopped right after removing his pants and seemed to be looking at him, analyzing him.

But when Naruto thought of saying Kakashi's name, he felt something wet touch his member. He felt Kakashi's hand on his chest, pushing him to lie down on the bed while his mouth began to caress Naruto's member. It was beyond what he had imagined; Kakashi touched his nipples, hardening them, and his other hand was on Naruto's thighs, which sometimes tried to close in spasms of pleasure.

But Kakashi didn't let Naruto come; when he was close, he felt the rhythm slow down, almost stop, and then he was kissed on the thighs and lower abdomen. Kakashi began climbing kisses over Naruto's chest, lingering on each nipple, giving muffled chuckles when he saw the student moaning uncomfortably from so much pleasure. When Kakashi reached Naruto's lips again, he kissed him as if it was from one of the books he constantly read. It was hot, perverted, with a bite on Naruto's lips that seemed surprised and delighted.

Kakashi placed a finger on Naruto's lips, then inserted it into his mouth. Naruto sucked willingly, and he would do the same with anything his sensei placed in his mouth. That finger slid down Naruto's body to his entrance and entered without mercy, making Naruto squirm in surprise and pleasure. He couldn't help calling Kakashi's name, saying "Kakashi Sensei! Please!" between moans as he was fingered with that finger and then with another. Seeing Naruto beg was beautiful for Kakashi, who could see him.

Naruto felt the fingers leave him, and soon Kakashi positioned himself between his legs. He took a deep breath while being penetrated, slowly. When it reached the end, and the back-and-forth began, Naruto felt his blindfold ripped off. He blinked a little, his senses confused by the faint streetlight, and the clean, maskless, beautiful face of his sensei. They admired each other for a moment; Kakashi bit his lips, and Naruto looked at him completely in love, open, and vulnerable. Both felt they shared a secret, and Kakashi leaned closer to Naruto to kiss him.

— Was it what you imagined? — he asked, and Naruto sighed, now able to place his hands on Kakashi's face and caress him, especially over the charming mole he had.

— It's much better...

— Then prepare for it to get even better. — said Kakashi. With that, he kissed Naruto's mouth torridly while resuming strong, now deeper thrusts, pulling the boy's legs up, which soon wrapped around his waist. Naruto's member only rubbing against Kakashi's abdomen until reaching the peak when both came almost together. Naruto first, loudly calling Kakashi's name, his whole body contorting and tightening around his sensei's member, who came next, muffling his voice on Naruto's shoulder, groaning gutturally as he climaxed inside his student.

All that can be said is that, after this, the secret endured throughout the entire ninja war. And in this version of the story, when Naruto was hailed by the entire village for defeating Pain and managed to save the life of his precious sensei, they entered into a relationship, now openly and well-regarded. Guy was Kakashi's best man, and Shikamaru was Naruto's at their wedding. P.S.: Everyone made a video for the couple, including that son of a b* Orochimaru.
