I am Saitama - Chapter 33: A day with Mizuki (Part 1)*
🕑 Added 2025-08-16 23:29:15 +0000 UTCCLAP! CLAP! CLAP! CLAP!
"Oh my–unh! God! You are too big for me!" Said the heroine known as Captain Mizuki who on that moment was laying on her bed as the bald stud behind her, thrusted into her relentlessly.
The identity of the bald stud? It was no other that Saitama, also known as the One Punch Man, although in reality he only was a reincarnated nobody who had the luck to reincarnate on the most powerful being of this universe.
CLAP! CLAP! CLAP! CLAP! CLAP!
"Yes! Yes! Yes! I can't–god! I can't keep any longer! This dick, hnggh! Is just too much!"
Mizuki's usual confident and sometimes bubbly voice was now a mess of moans and screams, all because of Saitama, her rocking hot body worked by all her years of training and high-level physical competitions payed off for a little while, but after 15 minutes of constant pounding, she just couldn't take it anymore.
Her back arched while her heart-shaped ass bounced with every thrust from his well endowed boyfriend. Her legs fully slick with sweat because of the sexual activity just couldn't stop trembling and every time she received a thrust from the bald hero, her ponytail swayed on the air just from the pure force of the impact of his cock.
Meanwhile, Saitama's mind wasn't fully focused on the activity as he was analyzing how did they go from them having a coffee like any other couple to fuck each other like animals on mating season.
Let's see...I remember she invited me for a coffee when I was talking with Tatsumaki, that incidentally, I don't know if what happened could even be considered a conversation as the little goblin froze in the mid of it. But the question is why did I let myself end here when I still had to work?
He thought as he gripped tightier the ass cheeks of her girlfriend, earning a moan from her.
"Aaah, yes!!" She purred on the sluttiest way possible, making Saitama thoughts pause.
Oh...that's why. After coming to this world, I discovered that I like having sex.
He grinned, as he resumed his task with renewed vigor, his twelve-inch cock now wet with vaginal fluids and his own cum kept on the task in had of pistoning in and out of the ex-olympic athlete with a faster rhythm.
Every time his cock got out, a little bit of a combination of fluids dripped from the hole of his girlfriend onto the bed, just so that inmediately afterwards, a wet sound like a Plop was heard followed closely by the clap-like sound that followed when his dick smashed went all in and smashed with the muscular but fat ass.
PLAP! PLAP! PLAP! PLAP! PLAP!
CLAP! CLAP! CLAP! CLAP! CLAP!
"Oh gooodd!! I'm cumming again! I swear I'm cumming againn!!" She moaned.
Meanwhile, Saitama raised an eyebrow on this.
Again? How many times did she cum already? 3? 4? And how long ago did we start? 15 minutes? Shit!...and to think that in my past life I was a virgin. He thought as he felt how her walls tightened around his cock as she came all over him.
Meanwhile, his giant balls continued on slapping off her each time he drove in, not easing off even as he felt her juice flooding out on his dick and dripping through her hole, wetting her bed even more.
This resulted in all of his thrusts sounding even wetter than before. His usual claps on her ass had transformed into a more wet and less dry noise, similar to when his dick came out of her hole.
PLAP! PLAP! PLAP! PLAP! PLAP! PLAP!
"Shit." The heroine weakly mumbled as her body tried to recover from the multiple orgasms that still rippled through her body, all of this to not avail as his boyfrined keep thrusting into her without a single sign of slowing down.
So she did something that Saitama didn't expected.
She passed out.
The bald hero discovered this almost inmediately as her back wasn't arching now, and her previously standing head was now resting on her pillow.
So he took that as a sign to withdraw his cock from her wet pussy.
Pop!
He pulled out of her fucked and battered hole, her pussy was now a giant gaping hole, looking like a big cave between her legs that was dripping both with her juices and a little bit of his pre-cum.
Seeing this, Saitama only had one thought as he standed up on his two feet and observed what his brief but intense fucking had made.
The previously inmaculate small double size bed of her girlfriend, was now a mess of body fluids, sweats and scattered sheets. And now was also the unconscious naked body of her girlfriend resting over all that.
Well, this is a mess. He thought as he analyzed the scene and noticed how sweaty Mizuki's body was because of the sexual exercise.
Well shit, I bet that not even when she won the Athletism’s gold medal on the Olympics she was sweaty and tired as now, putting that aside, she looks so cute when she sleeps. He thought to himself as he slowly and carefully made his way to the apartment bathroom to take a shower, being careful not to wake her up.
(Few hours later…)
The noise and smell of something cooking itself invaded the apartment, all the way to Mizuki’s bed, which resulted in the unconscious sniffing of the heroine and the waking up of her body because of the smell.
That made her move, carefully stepping out of the bed, her muscles still trembling faintly from exhaustion. Her naked body was still on fire because of the things she had done with her boyfriend, while she covered herself with one of her sheets (that still smelled faintly like cum).
However, that didn’t bother her now. Her only concern was finding out where that delicious smell was coming from. So she padded out of her bedroom, bare feet brushing softly against the floor, following the inviting aroma.
And there he was.
Her boyfriend—the same one who had almost left her unable to walk a few hours ago—was standing casually in the kitchen, apron thrown carelessly over his bare chest, as though this was the most natural thing in the world. The pan hissed when he flipped its contents with precise, practiced ease, the golden-brown surface of food catching the light. He didn’t look like a man who’d just exhausted her beyond reason. He looked calm. Relaxed. Almost like he belonged there.
She must have made some noise without noticing, because almost immediately he turned his head towards where she was standing.
“Good morning, Mizu! I made breakfast,” he said in a calm tone, with that small, understated smile of his that never failed to make her feel strangely at ease.
She smiled at this, tugging the sheet a little tighter around her body as she walked into the kitchen. Her legs still wobbled slightly, and she thought with a mix of embarrassment and amusement that he really wasn’t exaggerating when he said he held back most of the time.
The table was already set—two plates, steaming food, and even mugs filled with tea waiting. It felt almost surreal to her. A few hours ago they were tangled together in a mess of sweat, heat, and near-violence, and now he was serving her a home-cooked meal like some dutiful husband.
“Wow…” Mizuki muttered, sliding onto the chair opposite him. “You’re full of surprises, aren’t you?”
“Not really,” he replied, scratching his cheek with a hint of awkwardness. “I just thought you’d be hungry after, you know… all that.”
Her cheeks warmed, and she quickly buried the moment by spearing a forkful of food and stuffing it into her mouth. The flavor hit instantly—rich, savory, comforting—and without realizing it, she kept going, bite after bite, like someone who hadn’t eaten in days.
He watched her for a second, amused. “Guess it’s not too bad then.”
Mizuki only managed a muffled, “Mmh!” through a mouth full of food, still chewing energetically.
For a while, the room was filled only with the sounds of her eating and the soft clinking of cutlery. He ate at his usual unhurried pace, while she demolished her plate like she was making up for lost calories.
When she finally slowed down enough to breathe, he took a sip of tea and spoke again. “Today, I’m planning to keep helping out with the reconstruction in A-City.”
Mizuki blinked at him, mid-bite, her cheeks puffed out adorably. She swallowed, tilted her head, and frowned lightly, as if her brain was still struggling to catch up. “Eh? Already?”
“Yeah.” He leaned back a little, eyes steady on her. “There’s still too much to be done, and I can’t really sit around. Besides, it’s… important.”
She let her fork rest on the plate, lips pursed. Normally, she’d be all fire—bubbly, determined, ready to jump in at the mention of work or training. But right now, that energy seemed buried under the softness of the morning. Her hair was still messy from the pillow, her sheet slipping slightly to reveal the smooth line of her shoulder, and the only thing she seemed fully invested in was her food.
Her usual spark was there, but dimmed, as if it hadn’t woken up yet. For once, Mizuki looked less like the unstoppable heroine everyone knew and more like a girl who wanted to stay wrapped up in the warmth of the moment.
Still, she smiled at him again, softer this time, and nodded. “Then… I’ll cheer for you from here. But don’t overdo it, okay?”
He chuckled at that. “You’re telling me that? After last night?”
Her face flared bright red, and she jabbed her fork at him in mock offense before immediately shoving more food into her mouth to hide her embarrassment.
Saitama’s phone buzzed against the table just as he was finishing his toast. He picked it up, expression flat as always, and answered without hesitation.
“Yes.”
“Uh-huh.”
“Got it.”
Mizuki tilted her head slightly while chewing, eyes narrowing in curiosity, but she didn’t ask. He wasn’t giving her a chance anyway—the call was short, his responses minimal, and when he hung up he just slipped the phone back onto the table like nothing had happened.
She swallowed the last bite she’d been absently working through. “So? What was that about?”
He leaned back in his chair, stretching lazily before giving her a faint grin. “Good news. I don’t have to go. Reconstruction in A-City is almost done—thanks to the Association sending every available hero, and… y’know, me.”
Her face lit up immediately, the faint fog of sleepiness evaporating as if she’d just been struck by lightning. Mizuki sat straighter, her messy bed hair bouncing slightly. “Wait—so you’re free today? That means we can actually have a day together. Just the two of us! After all, today is my day off from training and from being a hero, which I take every two weeks.” She said on her bubbly, energetic and impossible to ignore tone.
He noticed that her voice carried that spark again after almost killing her with his dick last night, the one that was pure Mizuki and that he loved to hear.
Saitama blinked at her enthusiasm, chopsticks still dangling in his hand. “Uh… maybe. I mean, I was planning on checking on Genos, and… Bang asked me to stop by his dojo, and—”
She pouted immediately, lips jutting forward in mock annoyance, and he stopped. The silence hung for a moment.
Then Saitama sighed quietly, looking down at the food he had cooked, the simple domesticity of the morning, the way Mizuki’s eyes were practically glowing now that she saw the chance to drag him out for something normal.
He thought back to it all: he had reincarnated into this world. A world that wasn’t supposed to belong to him. And yet here he was, sitting across from a beautiful heroine who was also his girlfriend, in an apartment that felt like home.
What was he doing worrying about schedules and obligations? Wasn’t this exactly what he’d wanted? To be free of those tiring and useless things and enjoy his life? A chance not just to be strong, not just to play a role in some story he already knew, but to live?
He cracked a small, genuine smile. “...You’re right. Screw it. Let’s do it. A whole day. Just us.”
Mizuki’s reaction was instant—she clapped her hands together, her sheet slipping dangerously low before she caught it, laughing with her usual bright tone. “Yes! Finally! You and me, no monsters, no Association calls, no training—just us.”
Saitama chuckled lightly at her excitement, shaking his head. “Guess I’ll have to put Genos and Bang on hold. But whatever. They’ll survive without me for a day.”
She leaned forward on the table, resting her chin on her hands as her grin softened into something warmer. “That’s the spirit. Today, you’re mine.”
And for once, Saitama didn’t argue.

Author Note: I changed the label to indicate chapters rated 18 to (*), because otherwise Patreon hides them and I have to erase them. Putting that aside, this chapter and the next will have a more slice of life vibe (with a little smut of course), after all, I already gave you too much action lately, so I hope you like it.
