Genos moved quickly as he prepared lunch for him and Saitama. They had just finished fighting against a powerful enemy and she had been quite filthy afterwards. Her suit was now in the wash being cleaned and her gloves were drip drying.

To ease her sore muscles, relieve stress and clean herself off; Genos had suggested she take a bath and leave the food to him. She trusted him and he had reassured her with his technological abilities he could handle it just fine.

After she had saved his life and taken him in as an apprentice; Genos had spent his time and energy being helpful to Saitama and developing his skills. He owed her his life and he would continue to repay that debt.

However, over time he had started to feel something entirely new for Saitama; new feelings within his system grew when he was around her. His concern over her well being had increased to that of the similar feeling that a human would have for their partner. He got impatient, hateful or angry if another male even so much looked at her.

He found his systems going into a flux or overdrive when she would walk around barely dressed. When she would cuddle up to him at night he would feel himself overheat but at the same time feel happy too.

He couldn't process or understand what these feelings for Saitama were; he had never acted this way around another human female before. So why was this happening around her?

Suddenly the bathroom door opened and he heard Saitama sigh pleasantly. It seemed she was done with her bath already. Usually she took at least 4 hours but today she had decided to on just two.

"Phew; I needed that!" she sighed happily. While the fight had been relatively easy; stress had been building up and that soak really hit the spot. It was amazing how relaxing something so simple as a bath could be.

"Sensei I'm just finishing prepping the food; Please wait a second" he said politely as he finished up the preparation. He had planned on her coming out later so he was still in mid prep instead.

He heard the floorboards creak and then her footsteps head towards the living room. Surely she was going to get dressed, right? It wasn't decent for her to walk around naked; I mean it was her apartment and he was just a roommate. But didn't she care about people in the street seeing her?

He turned to argue as she got closer but lost his voice the minute he did. His system temporarily shut down and he could not process words from his memory. He felt his system gage get hotter and hotter to the point of overheating. His memory circuits wouldn't function and he felt oil dripping from his nose.

There standing in the doorway with shiny smooth skin, wearing a towel that barely covered her boobs and flashed a lot of skin; was Saitama. Her body was flushed and warm from the bath; water droplets still running down her legs, arms and breasts. She was panting a little but looked very refreshed; energetic even.

If he was a human male he was sure he would have popped what Saitama referred to as a "Boner". It was what happened to the heterosexual male gender when they found a human female attractive enough to mate with.

As the smell of food wafted up her nose she smiled "That looks good; you really got a knack for this Genos" she complimented cheerfully. While she thought his power was pretty great already; his cooking skills far succeeded hers.

Genos felt himself mentally cry; not only was he seeing Sensei look so beautiful but she was complimenting him on his cooking. This was the happiest day of his entire life. Nothing could beat the joy his system was filling him with right now.

She saw his expression and looked a little concerned "You ok Genos? Is your pressure system damaged?" she asked curiously. He was pretty red in the face; was something overheating?

Genos snapped out his trance "No Sensei; not at all" he responded quickly. He couldn't let her see him looking like such a pervert. She probably didn't even like him that way anyway; she most likely saw him as a kid.

Saitama wasn't convinced but decided to leave it be as she didn't properly understand the way Genos worked. But one thing she knew was that Genos didn't lie to her. However she was hungry and was more interested in feeding her empty stomach.

She shrugged quietly and sat down; it all looked so good and she couldn't wait to dig in. Man, was she hungry. Everything smelled amazing; grilled Gyouza with pork (discount of course), miso soup, a whole cooker of rice; with a side of pickled radish.

"I applied some of my wages as a hero to buy you more food mistress Saitama. There is enough food in the fridge to last you a while" Genos explained kindly. Even though she was a classified Hero; she didn't have an enormous pay check compared to other heroes. She was a lower rank so her money amount was substantially lower.

Saitama stared at him in awe "But Genos; shouldn't you put that towards new parts?" she asked anxiously. With the amount of times Genos had gotten damaged she wondered how she didn't have an extensive bill. However, she did also wonder why he didn't have new appliances added to his body.

Genos was touched by her concern; she meant a lot to him as did she to him. He didn't know what he would do if someone tried to hurt her (if they could that is). However if that did somehow miraculously happen; that person would have dug their own grave.

Next to Dr Kuseno she had saved his life from an enemy who was able to overpower and almost destroy him. She had helped train him even though it was taking time to grow stronger and she even treated him like an equal.

She never gloated about her powers; even though she could easily destroy earth without limitation. She was humble and laid back and just acted like a normal woman; despite her immense capabilities.

"I already get repairs for free Sensei; I am like a son to Dr Kuseno. With all the good I do in his name I think he sees my repairs as a thank you for my actions" Genos explained.

Saitama hummed thoughtfully but didn't bother arguing; it would probably end in a long montage of his relationship to this Kuseno guy. As long as Genos was happy with what he was doing she wouldn't make him do anything he didn't want.

She picked up her chopsticks and picked up a Gyouza and popped it into her mouth. Flavour and crispiness exploded in her mouth and she internally screamed. She was so used to making quick meals that she never got to eat full course meals.

"Damn this is good! Who guessed my disciple would be such a good cook!" Saitama cried mentally. For all that Genos did stress her out by over reacting or over thinking things. He meant well and was a good soul; after all he had been through a lot for a kid.

She hummed happily as she enjoyed her mouthful of food; thank god for discount sales. What would she do without them? They saved a shit tonne on her shopping bills that was for damn sure.

Genos watched Saitama's face light up with joy as she ate. While she was null and void to most emotions; there were still some things that riled up emotion in her. However to most people they would seem like weird things to get upset about.

If she missed a sale Saitama got upset or sulked for days on end; pissed that she missed the chance to get a bargain sale on food or clothes. One time she missed a sale on discount sanitary pads and pajama's and sulked for a week.

If someone made a comment about her head she would punch their face in. It was one of the things she was most sensitive about. There were times even now if someone brought it up instead of getting mad she was just twitch to show she was effected by the subject and they shut up immediately.

Damage and repairs; with many attacks that had happened in the city. Saitama had received some from enemies and of course beaten their face in. Repairs to homes did get pricey after all.

Finally, perverts; Saitama hated perverts with a vengeance. She would always break their hand or punch them should they try anything. She wore her costume because she liked it; not because she did it for the service.

Because these things so upset his mistress so; Genos would try and help her in some way or another to be of help to her. However lately with his unexplained feelings towards Saitama; he was conflicted as to whether or not he was also like those men.

He would set the date for the sale into his memory and when it ended. That way he could remind Saitama and she could get her shopping for meals. That way she could get all her feminine products and replace clothes that were damaged or no longer fitted her.

Genos would glare menacingly at people who stared at Saitama's head before they could make a comment. If they did he would loom over them and threaten them to repeat what they said to which they would run off.

Strangely; Genos had started to find himself feeling rage or the desire to kill the males who were perverse towards Saitama. While he usually just broke their hand, he found himself wanting to kill them lately; but he did not know why.

Saitama saw Genos expression and tilted her head to the side curiously "Something up Genos? You look kind of pissed" she asked curiously. While Genos's expression had started off calm and contemplated; the longer he started it eventually became angry. Just what had pissed him off so much?

Genos realized he had let Saitama see him acting unlike himself. Surely this would worry her and cause her to be troubled. "I…Its nothing sensei! Please eat!" Genos quickly reassured her picking up his own chopsticks and eating food.

Saitama watched Genos eat quietly not saying anything. He was definitely acting unlike himself; even if he was twitchy sometimes. She peered at him quietly but settled to eating her food. She could ask him about it later; but for now she would enjoy this good grub.
