Saitama sighed heavily and pointed her finger accusingly at Genos. This had been bothering her for a while and now she was finally going to confront the problem. If she left it alone things would only get worse.

"Genos; from now on you are forbidden from calling me Sensei" she said sharply. She knew this was going to be hard on her but it was necessary. If things continued the way they were she would only get unwanted attention.

Genos stiffened and her face became a look of horror. She dropped the pot she was cleaning which landed on the floor with a loud clang. She had thought something was wrong with Saitama for a while but she had never addressed it.

She now felt so foolish for not going with her instinct and leaving things be. Now her sensei was angry at her but there was nothing she could do about it. However she would try and make amends for whatever she had done.

Saitama winced at the sound of the pot being dropped but didn't mind it. I mean it was made out of metal so it wasn't really breakable. However she was worried about if it may have dented or cracked the floor.

Genos then slammed her hands down onto the floor and curled up into a bowing position; her head cracking the floor a little. "I'm sorry Sensei! Please forgive me for upsetting you" she cried apologetically.

She had tried to be useful to Saitama, to be polite to her and help her as an apprentice. But she had seemingly done nothing but get in her way. She would never forgive herself for causing Saitama trouble.

Saitama was rather stunned by Genos's reaction and blinked in awe. She really hadn't expected Genos to react in such a manner. I mean she was used to her being high maintenance but this was a little over the top.

She laughed nervously and scratched her face awkwardly "It's…It's not really a serious problem Genos" she explained casually. When unless you counted the fact that she felt like a pervert. Yes, though she didn't show it Saitama had a conscience that made her self-aware.

Genos was relieved to hear such a thing. But was upset that Saitama would confuse her like this; it was not helping her system one bit. She was not as good at understanding humans especially Saitama.

She sat up quietly and folded her arms crossly; her amber eyes filled with displeasure "Please don't make such inappropriate jokes sensei" she said firmly. She had been very effected by her words.

She was used to her sensei making bad or light humored jokes. Not cruel ones that messed with her systems and caused her to panic. She had feared that Saitama may throw her out.

Saitama sighed heavily once more; it seemed that Genos still didn't get what she was talking about after all. "I wasn't joking Genos" she replied dryly. While she did care for the young cyborg; this was a serious matter that needed addressing.

Genos sat down on her knees before Saitama at the table. She would need to be seated in order to fully understand what the hell was going on. While she found Saitama hard to understand; today was more difficult than usual.

She looked at Saitama her eyes filled with confusion but her face calm yet conflicted. You could hear the gears whirring in her head as she thought. She was using all her systems to try and figure out what was going on. What the hell was happening and why?

Saitama relaxed and became thoughtful; this was more awkward to explain that she expected it to be. She really wasn't happy about this one bit. She wasn't really used to talking about this kind of subject.

While she was a laid back, casual and indifferent person; she was still human and had some feelings she could still express. "Well…you are still my trainee and that means you are my disciple…" Saitama explained her tone wavering.

Genos was indeed working under her and learning all she could about becoming a strong hero. She was doing well and learning good moral codes; but she still seemed to feel imperfect.

Genos gripped her hands into fists; the waiting was making her systems act up and her core was pulsing in her chest. She believed this was what humans called nervousness?

Saitama relented and looked her dead in the eye "When we have sex you call me Sensei too. I do have neighbours and they will think I'm a pervert or something like that" she explained awkwardly.

Saitama didn't care what people thought about her in the slightest. But she was cautious of how her actions effected other people. One of the biggest assets of being a hero was being aware of how your actions effected others.

She could only imagine what her neighbours would be thinking when they heard a younger female voice crying out "Sensei" at god knows what time of the night or day. Hell sometimes there were little kids playing in the nearby areas.

"People are going to think I'm a cougar or some form of dirty older woman who has a thing for teenagers" she explained hesitantly. She already got enough trouble as it was from losers who sent her spam mail for being a faker.

She got attacked by the odd pervert while out or people staring at her breasts. The last thing she needed was people thinking she was some form of pervert who had a teacher kink.

She was aware some people had a kink for that and even watched Porno of it. But she was not one of those people and didn't want people getting the wrong idea of it. She didn't like being accused of things she didn't do.

Genos frowned and tilted her head a little "But you are my sensei and thus I must call you as such. What else would I call you?" she replied abruptly. She was only being respectful and speaking honestly.

She realized her tone came across as impatient or rude; but she couldn't help herself. She didn't understand what was going on at all. Her systems were not giving her sustainable answer to the situation.

Saitama hummed thoughtfully and leaned back a little staring at the ceiling. She wracked her brain of a good nickname before she found the right one. She had always wanted a nickname; even as a kid.

She smiled playfully and looked at Genos "How about Sai? Or Sai-chan?" she suggested. I mean it was a shortened version of her name. Plus it did sound just a little cuter like one of those Yuri comics Genos would sometimes read.

She knew Genos was just trying to be respectful but she had told her name when they first met. It would be nice if she could use it just once. She hadn't heard someone call her name since she was in college or school.

Genos displayed a look of disgust and shame upon hearing it. It just didn't feel right and she felt like she was being dishonorable. "No Sensei I cannot. I am merely your student and that is all. To call you anything else would be rude" she retorted defiantly.

She would stand by her decision even if it upset Saitama; which she knew it did. She hated that she was going against her sensei but she couldn't bring herself to say anything but that word.

To address Saitama as anything but Sensei just made her feel like she was insulting the woman. Like she was taking away Saitama's honour in some way. And as a Hero she could not allow herself to do something like that.

Saitama groaned wearily and tilted her body back against the futon pile. She was getting nowhere with this and she was right back to where she started. They were just going round in circles.

Genos was a highly stubborn individual and it often caused more problems than most. This meant she would stand by her decision no matter what. It was both a problematic and useful personality trait to have.

Suddenly that was when it hit her. She knew it was cruel but it was the only way she could think of to fix this problem. Plus, it would end the rumours that any of her neighbours may start.

She then pointed her finger at Genos again her expression solemn. She was going to have to be serious for this in order for the message to get across. Otherwise it would not sink into Genos's system.

"Genos. From now on you are banned from calling me Sensei when we have sex. Do you understand?" she said sharply. That way Genos call her by her first name; she had no other option. Plus She would feel less like a pervert who was doing something wrong.

Meanwhile Genos had gone quiet and simply nodded in understanding. If this was what her sensei wished then she would obey her demands no matter what. She would do whatever she wished if it made Saitama happy.

Content with clearing their problems; Saitama stretched and sighed in relief. She felt a few bones in her back crack making her feel comfortable. You'd never think that sitting down would cause so much aches in your body.

"I'm going to take a nap for a while. But wake me up in a while so we can go shopping ok?" she said casually. There was going to be a discount sale on noodles and pork. She had been wanting to make ramen for a while now.

It was getting chilly and she fancied something warm in order to fill her belly and keep out the cold. Ramen would hit the spot pretty well too. Plus she hadn't eaten it since her student years and it would be nostalgic.

Genos nodded quietly but didn't move. Her head was bowed causing her blonde hair to tumble over her shoulders a little. She was trying to hide her unhappiness and conflict from Saitama.

She wasn't very happy about being unable to say her sensei's name anymore. But if it would bring her relief she would follow through with her demands. She would try her hardest to remain quit during their intimacy.

"I must control myself from now on. If that is what my sensei wishes of me" she thought to herself quietly. She was already causing Saitama enough conveniences as it was; she did not wish to cause her any more.
