it all started one afternoon after school.

That hidden memory took place during the last few weeks of her final year at the academy.

Naruko had been punished for repainting the faces of the Hokages for attention and as one might expect, she was caught. But not only did they make her clean up the mess she made at the Hokage monument. But as an added bonus, they made the cleaning staff leave early that day since the Uzumaki was the one to clean all the senior classrooms.

That was why she had stayed late at the academy even though all the students and teachers had already left. The absence of people on the premises highlighted the idea that Naruko was the only one in the whole place, and would have been if it wasn't for her surveillance making sure she didn't escape.

"Hey Uzumaki, you missed cleaning up there" her teacher Mizuki had said with an amused smile plastered on his lips as he watched the blonde clean the entire classroom with just a piece of cloth and a bucket of water.

The girl had looked at him with annoyance. she wanted to tell him many things but the experience of several punishments would know that it would be useless against him. So with a frustrated sigh she took the bucket of water and carried it to where he said it was still dirty "you missed cleaning up there" muttered Naruko with since as she dipped the piece of cloth in the water and began to clean up.

Part of her bad mood was not due to having to stay at the academy until late, but that she has to clean in front of Mizuki and obey his orders. She felt uncomfortable having to do what he told her to do to clean the place, and that she also had to be on the floor on all fours while he watched every single thing she did sitting from his teacher's desk. 'ughh, damn, this wretch treats me like I'm his servant.'

She was embarrassed to think like that, but she kept it to herself to get on with her work.

That way, in 2 hours, through the windows the evening light was already filtering in. Naruko had cleaned 3 classrooms under Mizuki's watchful eye and judgment. She only had 4 more classrooms to go. Although she had nothing to do after the academy, Naruko wanted to leave.

Cleaning tables, windows and the floor, the Uzumaki reluctantly complicate her punishment while grumbling until she heard the classroom door open.

The girl cleaning the window glass turned to find a woman standing in the doorway.

She looked young, perhaps no older than 25. Her eyes were black in color adorned by a pair of long eyelashes. her coal-dark hair was coiled in a braid that ran down her back to just above her hips and a fringe framed her face on both sides.

That woman was wearing a tactical vest over a dark purple short-sleeved blouse, and had the classic combat pants and sandals that are characteristic of ninjas.

"Hi Mizuki" she spoke shortly after opening the door and walked over to where Mizuki was. which surprised the blonde, the other female teachers were not usually so friendly to him for some reason.

"Hello Tsubaki, what are you doing here?" replied Naruko’s sensei welcoming the strange woman entering the classroom.

"I just got back from a mission and since you almost always stay after class I thought I'd come say hello" she said as she stood next to Mizuki.

From a distance, the blonde looked sideways at those two as she pretended to clean the window. It took her by surprise that someone would come here, let alone appear to be a friend of Mizuki.

Naruko tried to ignore them, but those two soon started a conversation between them. Naruko was annoyed that she had to listen to their cheerful chatter while she was being **** to clean the place. but there was something else that bothered her about the chatter between the two.

As Naruko was leaning forward to clean one of the tables, she slyly looked up to see them and felt a hint of annoyance when she saw them so happy. But the most important thing was how inside Naruko formed a kind of anger when she saw that Tsubaki woman sitting on one her sensei's legs, wrapping her arms around his neck and her sensei's hand rested on her waist as he looked at her with pleasure, as if she was a sight worth seeing.

"Tsk" 'but who scratched that broad for Mizuki-sensei to let her be so clingy?' Naruko grumbles at the scene playing out in front of her. Her displeasure and anger only increased all at once when she saw the raven-haired one sink her face into Mizuko's neck. Naruko narrowed her eyes and glared at Tsubaki as if she was trying to throw knives at her with her eyes. She was so focused on watching her with evil eyes how that woman was acting so close and trusting to her sensei that it took her a while to realize that Mizuki was looking at her.

When Naruko finally realized that she had been discovered, she lowered her head and began to clean with intensity, as if wiping that table would erase having been caught.

.... After a couple of seconds in which Naruko heard nothing but the kisses that woman was giving to her teacher, she looked up again with curiosity.

There she found only the back of that harpy sitting completely on both of MIzuki's legs, rubbing her body against his as she continued to kiss him audibly. Naruko's eyes widened like saucers seeing them acting so indecently as if she wasn't even here. and her jaw dropped in disbelief when Mizuki began to shamelessly caress Tsubaki's body.

If at that moment the Uzumaki had had a mirror, she would have seen her face completely red and sweating with nerves.

'eh~!!!, what the heck are they doing? they are at the academy and I am still here, did they forget or don't they care?. They can't do lewd acts in the middle of a classroom with a student present' Naruko thought in panic as she tried to ignore the hot indecency going on just a few feet away from her 'they are crazy, I'm sure if it was me who tried to do the same thing as that woman. Mizuki wouldn't allow me to...' As the blonde thought about that, an image was created in her mind without her will: her sitting on Mizuki-sensei's legs just like Tsuabki, giving many kisses to him while he was caressing her body with joy.

That image created a pleasant tingle in Naruko's stomach and an even redder face than it was. Naruko disliked Mizuko, she resented having to be punished while he was having a good time. She wanted nothing to do with that silver-haired man, she definitely did not want to be in Tsubaki's place and feel that pair of strong hands on her body.

The next thing she did was to shake her head hard to try to erase those thoughts while trying to sit down on her work, while her sensei and that woman kept touching each other. Naruko even startled when she heard a moan (or maybe she just thought she heard it).

The Uzumaki had managed to clean up the classroom. She was satisfied since that meant she was closer to finishing her punishment and since she had to go to another class, Mizuki would have to stop flirting with that woman.

But then Naruko realized something. that she still hadn't cleaned the stairs between the seats.

She preferred to leave it last because they are right in front of Mizuki and to clean them she had to stand with her back to him and get on all fours showing her butt to him. That wouldn't have been so bad except that Naruko constantly had to feel the pressure of Mizuki's gaze on her.

She turned her gaze back to the couple who were still going about their business, looked back at the stairs and thought to herself.

'.....well..... at least he won't be looking at me' The Uzumaki thought before deciding to finish that last part.

Placing herself on the first step, Naruko got down on all fours to start cleaning up now that her sensei was busy with that woman. She wet the piece of cloth she was cleaning with and got to work. Her mind told her that she would finish that soon now that she didn't have to endure Mizuki's constant hard stare since he was now busy with that girl, Tsubaki.

At first the blonde didn't seem to have any problems and that she could finish without anything bothering her, but she soon noticed that she was wrong.

As she finished scrubbing the first two steps, the Uzumaki began to feel strange. It was a different feeling than having to feel that heavy gaze of her sensei on her that made her shudder. This time she felt light, as if she wasn't carrying anything, as if she herself didn't have to bear anything anymore.

If Naruko had to use one word to describe what was happening it would be:.... <<empty>>.

Or <<bored>> also work. She had gotten so used to her sensei looking at her at that moment when she felt so exposed to him, that she felt uncomfortable not having his eyes on her anymore.

Still cleaning those steps, Naruko looked over her shoulder at her sensei who was still playing and flirting with Tsubaki instead of doing her job of watching. This made Naruko angry, was he forgetting that he had to see her and control her to do her job?, why stay if he wasn't going to do his job?.

'that woman' Naruko thought, annoyed by Tsubaki's appearance and the continuous attention Mizuki-sensei was giving her instead of Naruko, she refocused on her work while cleaning the steps with frustration '... if she hadn't appeared Mizuki sensei would be looking at me'. every now and then Naruko would turn back just to confirm that her sensei wasn't looking at her. continuously she would turn her gaze away, as if she expected him to.

Since Tsubaki had appeared, Mizuki no longer looked at Naruko, nor paid attention to her. That pair of cold eyes with which they watched her and he looked down on her were now all for Tsubaki. His voice with which he spoke to her in that firm way that made her obey almost naturally was no longer directed at her.

Naruko used to hate this punishment for having to be alone with that teacher who despised her and made her feel strange things. But now she really hated it when that woman showed up and stole Mizuki's attention.

'It's supposed to be just Mizuki-sensei and me. You shouldn't come to butt in slut' Naruko thought against Tsubaki for ruining her moments alone with Mizuki. "Mizuki sensei, I'm done" Naruko commented in a loud bitter voice.

After a long while, Mizuki looked at the Uzumaki again, who unconsciously improved her posture and relaxed her facial features to look (what she considered) prettier. Something she had never done with anyone before.

*sigh* "alright come on" Mizuki sighed with annoyance as she shook Tsubaki off and stood up. In parallel, Naruko's mood improved a bit as she watched him pull Tsubaki off of her.

That improvement didn't last long, though.

The three of them left the classroom to head to the next one, and all the way Tsubaki was hugging and clinging to her sensei's arm as he hugged her around the waist. A few steps behind, Naruko walked carrying her bucket loaded with new clean water, glaring at the couple in annoyance.

"tsk" the blonde clicked her tongue watching Tsubaki as if she wanted to open a hole in his head with her eyes. 'why can't you keep your hands off him, he's my sensei, not yours.'

When they reached the next classroom that the blonde had to clean, Mizuki informed her something she wasn't expecting.

"Uzumaki, this room will be cleaned by yourself" her sensei informed the blonde who looked at him confused "Tsubaki and I have things to discuss in private, so you stay and clean the place."

"What? but I-" Naruko tried to protest more puzzled than annoyed. like a child given bad news she was unable to comprehend.

"Easy Uzumaki-san" said this time Tsubai, who had a strong blush on her face, she seemed to be a bit sweaty and kept rubbing her body against the blonde's teacher "what Mizuki and I are going to discuss is very important to HIIIP!" the woman's words were cut off with a shriek of her own followed by the sound of a loud slap.

Something in Naruko knew that Mizuki had shut him up with a spank. he had given the Uzumaki so many that a part of her could practically make them out.

"Don't talk anymore Tsubaki" Naruko watched with shocked eyes as he used that harsh and firm tone against the woman, but this time's sounded slightly more commanding.

The blonde felt her heart clench when she saw for the first time that her sensei used that tone of superiority with another woman besides her. For Naruko, that was something he reserved only for her.

Her surprise was such that she couldn't do much when she saw the two of them walking away and she was left alone. When she wanted to say something they were already too far away. "Sensei..." muttered Naruko with disappointment when she saw how Mizuki preferred to go with that other woman than to be with her.
