Saitama never really payed much attention to Genos too much. Then again, the blonde cyborg never really made himself noticed unless he wanted to be. Saitama never noticed much about his behavior until today, Genos had been acting weird around his Sensei, and Saitama took notice.

"What's with you Genos? Being all stiff and monotone, what's with the new attitude?" Saitama asked, curious about his new behaviors.

"Sensei, are you sure you're new relationship with Tornado is... a very smart idea?" Genos asked gently, so he wouldn't trigger anything between him and his Sensei.

"What do you mean?" Saitama asked back, curious what Genos was insinuating with his question.

"Well... she is an S-Class, she's always in battle with very powerful people. She could die in battle as that is always a possibility." Genos pointed out, and while it was unlikely... it was entirely possible.

Saitama took that in.

"Genos, we both know how strong she is, she can take care of herself, it's a risk any hero has to take. I believe in her." Saitama responded.

"Ok... but what about YOUR strength Sensei? You could hug her, high five her, or... smack her butt or whatever, but she could get destroyed. What then?" Genos tried.

"Genos, just cause I'm strong, doesn't mean my very touch is catastrophic. I can control how much force is in what I do." Saitama responded.

"But Sensei!-" Genos tried again.

"Look, Genos, buddy, I'm fine. I know you're trying to look out for me, and I appreciate it. I really do. But my mind is made up, I have to believe in her or we can't be together at all. That's the end of it. So don't worry about me okay?" Saitama said with an understanding smile, which reassured Genos a little, but he didn't say those things cause he was worried about how his Sensei's relationship could be affected.

"Okay Sensei." Genos said disappointed.

A knock at the door diverted his attention, he could only guess who it was that would possibly want to see Saitama. Of course, the green haired brat had shown up again. She thankfully decided to not physically show affection while Genos was around. If she did, he might take a swing at her.

The two left after giving each other a small hug. Genos continued thinking, he had a gut feeling, but he still couldn't decide on a reason why he cared so much that the two were dating.

...

Saitama walked around downtown with Tatsumaki alongside him, holding his hand. The two were greeted with stares of all kinds. All varying from hate, shock, smugness, and happy. But it was mainly negativity geared towards the two heroes that had become widely known were openly showing that they were together. They had kissed and hugged outside, so of course it got on every social media platform within a couple days.

Everyone loved Tatsumaki as a hero, but everyone hated Saitama. But she took his advice and didn't let anything people geared towards her bother her anymore.

"That's disgusting." One person said, stopping in front of them.

"Hmm?" Saitama said, with Tatsumaki looking at the woman.

"You two holding hands and going on dates, you should be doing your jobs! And an S-Class should have higher standards than this filth!" The woman said to them, making people turn and notice.

Tatsumaki wanted to say something, not for her, but for what she was saying about her boyfriend, but he was a man, he could take care of himself. It didn't seem to bother him anyway.

"You filth! What makes you think you can-" the woman shouted, before a young man and his son came up and interrupted.

"Hey, caped baldy right?" The man asked.

"I prefer 'Saitama' actually." The hero responded.

"Look, I don't care what people say, but you saved my sons life when the deep sea king attacked... so thank you so much, I am in your debt." The man said, with the boy coming forward.

Saitama smiled.

"You're not in my debt, I was just doing my job." Saitama responded before giving the boy a small poke on his forehead.

"I see a hero right here. I can feel it." Saitama said the the boy.

The boys face lit up

"Really!? You think so!?" The boy asked excitedly.

"Sure, you just gotta train hard, you might even be stronger than me someday." He said before taking Tatsumaki's hand and begin walking away.

"I promise I will! I'll be the strongest hero of them all!" The boy called from behind.

"Train hard!" Saitama said before leaving finally.

Tatsumaki smiled at him. "That was so sweet of you." She said before floating up to give him a tender kiss on the cheek.

"You missed." Saitama responded before guiding her lips to his. No matter how many times she kissed Saitama or how comfortable she got doing it, her chest always exploded with emotion every time.

She floated upward and placed herself on his shoulders, she didn't even care how childish it might look. Saitama sighed a little but carried her along on his shoulders.

She placed her hands on his head and hummed a little as she was carried down the streets on his shoulders like she was a little girl again. Saitama made her feel that way anyways. She ended up hopping down when they went into a store or when they stopped for lunch. but whenever they finished, she would get right back on. Why should she deny it? It was fun.

The two simply walked around City Z for hours, stopping and doing interesting things as they pleased. As much as she enjoyed seeing him, the distance began to affect her a bit.

"We need to be closer, you're A-Class, you need to move closer to me or I'll move, we can afford if one of us moved to a different City. We both could move together, but it's necessary." She said, floating off his shoulders until she was equal height with him.

"Yeah, you're right." He agreed.

"Better talk to blonde boy then, tell him you aren't living with him anymore." She said as she stood on her own feet.

"Why wouldn't we be roommates?" Saitama asked.

She nearly slapped her forehead, how stupid could he be?

"Cause you and I will be living together, I don't want him in our ass when we live together." She said.

"OK." He simply responded with.

"He'll be okay with that?" She asked.

"Doesn't matter, if I'm moving to City A to live with you, I can still train him. But he'll have to get over it and live by himself and not be clingy when I leave." Saitama said.

She nodded her head, satisfied with that. Saitama only needed to bring clothes, her place had EVERYTHING he had, but better, and more room, what else could he bring?

...

"You're seriously leaving!?" Genos asked for a third time.

Saitama stuffed the last of his costume in his bag with the rest of his clothes and other little things he wanted to bring.

"Yes, you'll be fine, I'll still train you. You'll be fine Genos, you're not a lost puppy." Saitama said, slinging on his backpack, grabbing his duffel, and nabbing his cactus before going into the hallway where Tatsumaki was waiting patiently with a small smile.

Genos was in more danger of wanting to punch Tatsumaki more than ever before. She was now actually taking him further away than he'd ever thought, all the way to City A!

"Damn you, little green haired brat!" Genos shouted.

"Not green haired brat, my name is Tatsumaki to you." She responded before she led Saitama out the door.

"Take the house of you want Genos, just be sure to pay for it." Saitama said before leaving out the door, with Saitama running toward City A with intense speed as per usual. Tatsumaki followed at quite a fast pace while flying just above him.

Genos walked back inside and decided to clean up before he broke anything, as he was shaking with rage.

...

Saitama finished packing his clothes into the 3 extra drawers in Tatsumaki's large dresser, and hung his costume in the closet next to Tatsumaki's. He finished up, and then showered, he toweled off and laid on Tatsumaki's large and remarkably comfortable and soft bed.

He watched some TV, which was now on a 90 inch Plasma screen instead of his LED 45 inch. He would greatly enjoy plugging in his video games and playing on that TV. Saitama couldn't lie, it was much nicer than his crappy old apartment and he was enjoying it.

Her bedroom even had surround sound, so even though Tatsumaki had begun to shower in her bedroom bathroom... he could barely hear it.

She walked out in a white towel and saw that Saitama was in her room.

"Look away, Baka!" She said with red all over her face.

He simply closed his eyes.

She ran over to her dresser and took only about 5 seconds to get her Pajama Top and Bottoms on before she hopped into bed and snuggled next to him and watched the movie he was watching. It was an action movie, but halfway through, the romance scene came up and the two main characters confessed their love and kissed passionately on screen.

Tatsumaki was loving the scene and since Saitama didn't take the romance cue... she leaned up and kissed him.

Saitama researched more about girlfriends ok the internet earlier, a couple days ago. He read that if there is romance, at night, and in bed... the couple would "get it on".

Saitama turned to face her, and slowly ran his hands down her back, leaving kisses all down her neck. She let out little noises as she pulled him closer, wanting more, more...

Saitama slipped a hand under her shirt onto her bare back and began to lift it, with Saitama kissing her lips again. But when the shirt was lifted halfway, she hesitated. She remembered that she was small, flat chested, and very pale.

Saitama simply lifted it the rest of the way before she decided to say anything. He leaned down, looking her upper body up and down.

She blushed, 'I bet he's completely uninterested in me that way now.' She thought to herself.

But instead, he leaned further down, and whispered "beautiful" against her stomach.

And she believed him.

She pulled him back up, kissing him as she pressed her bare chest against his as well. She fumbled with his pants, but Saitama was much quicker. He had already reached down and yanked her bottoms off. She lay below him, naked as the day she was born. He reached down and slowly rubbed her clit, making her break away so she could moan.

"Wow, so wet, this is surreal." He said as he rubbed up and down.

"Ah! Mmmm, I'm... I'm g-gonna.." she said, she was so aroused by the kissing alone that only Saitama's mild rubbing was almost making her cum.

"No, not yet, we haven't even started." He said. She looked up and saw he unbuckled his pants, letting his manhood spring outward. She looked at it in awe, she had never seen a man like that before, and didn't anticipate the size of him.

She gulped.

"This... this is my first time, please be gentle." She said looking up at him.

"I'll do my best." He said, slowly prodding her entrance with his tip. He went all the way in with one quick thrust, deflowering her.

"Ahhhh!" She said, making her grit her teeth through it.

"Keep going, please." She said, with the pain fading fast.

He thrusted her again, and after 2 pumps, she came hard. But he had only started. He thrusted slowly at first, but soon he had gotten the hang of it and was perfectly in sync with her hips. She was screaming in intense pleasure, it was as he said, it was Surreal. She came many, many times that night, she was placed in several different positions. She went missionary, cowgirl, doggy style, you name it. He never seemed to be able to cum, and seemed to be able to go on forever, he was going to wear her out.

After what seemed like the craziest sex session, and the best one, in her life, he finally seemed to near climax.

"I'm almost cumming, looks like I'll have to go all out now." He said.

He had in her in doggy style, holding her hair and thrusting her as her tongue hung out and she moaned and panted and screamed in pleasure.

"Serious Move: Serious Piston!" Saitama said before thrusting her faster and harder than she could ever imagine possible.

The two came simultaneously, their fluids mixing together, the two screaming in sheer ecstasy before Saitama pulled out finally and sat, exhausted.

Tatsumaki was certain that no other man could ever make her feel that kind of intense pleasure, for hours as well.

Her legs and arms and body was so weak that she simply collapsed on her bed, panting heavily as she breathed heavy. It made her happy that she was the only one able to exhaust Saitama, ever.

His pants got both Tatsumaki and his own fluids all down the thighs from their crazy session. So he simply stripped it off him, since he could clearly be nude around her now, and was already nude and didn't care either.

Saitama clicked off the light, pulled her in and they snuggled in bed.

"Love you munchkin." Saitama said with a small laugh.

She smirked.

"Love you too baldy." She said before the two fell quickly asleep out of sheer exhaustion.
