He was really desperate to get away from that Piri-guy who's alias he forgot yet again. He knew that guy had a thing for men, he was not oblivious and certainly not an idiot, nor blind. How the hell had Genos found that one old picture of himself and [Y/N] at the Z-Con four Years ago? And why did he bring it with him? Now he had her elder brother hot on his heels for 'being so cute and sexy' with the reason of 'how could I have seen that when you always wear that dopey face of yours'. Saitama shuddered the guy was nice, as a person and as [Y/N]'s elder brother. Nothing more.

He really wasn't into men. Really. Seriously. He liked boobs, preferable the size of melons, thought he did like a good ass too, not that he had gotten much attention the past years anyways, because... you know. He wasn't too choosy.

So he dove trough the corridors at a high speed, trying to find a save place to hide, only to be found by that half-naked behemoth time and time again. Saitama's options ran low and so he did a rather desperate thing which, looking back at it now, wasn't so bad at all.

Sprinting as fast as he could, without destroying the homely residence, he searched the whole place for his only chance at surviving this night at all. When he finally found her he scrambled inside her room without knocking, taking her by surprise as she was nearly asleep at this late hour. The fight with the Monsters from before had taken it's toll after all.

"S-Sai-san?" She murmured sleepily, a cute expression on her face while tilting her head to the side. Out of breath he got to his knees, bowing low and nearly begging for her help to hide him from her brother. A few seconds later the words were realized and a shout occurred in the hallway behind him, sending shivers down his spine.

"Oh~ Saitama-swan~! Let me help you~!"

"Please?!" He added desperate, only taking note of her suddenly wide awakened demeanor at the edge of his perception. She nodded, looking around her room, while he sweated thick pearls, hearing heavy footsteps. There was nothing here he could hide in, or underneath for that matter. Feeling the foreign feeling of panic rising up in his chest he too searched for something frequently. The steps growing ever closer. There was only one thing where he could hide, was his conclusion and, as tempting as it was, he was not that desperate to actually-

"Sai~chwan~!"

He would definitely deny the whimper of fear that escaped him at that moment later on.

She leaned forward - part of him recognized her delicious, creamy breasts swinging with every movement she made underneath that tight top - took a hold of his pajamas and tugged him to herself, seemingly coming to the same conclusion as him. So, shortly before the time ran out and the doors slit open surprisingly silent, he found himself pressed into her Futon with his face full of soft, squishy pillows. A hand resided on his chest, his pajamas tangled slightly and a leg between his spread ones. If it weren't for the fact that she just saved the maidenhood of his sorry ass he would have totally savored this position he was finding himself in.

He might not get a drill out of many a thing anymore, but this right here was an exception - together with being hunted down by [Y/N]'s elder brother, that is.

In silence they laid there, the blanket draped in haste to cover the now semi-relaxing egg-head, before the doors slit close again and steps were heard outside.

'Don't think about it, don't think about it, don'tthinkaboutit, don'tthinkaboutit ', he thought desperately, but as much as he tried, the fact that they were squished against the lower half of his face and that he could feel her nipples grazing his cheeks as she slowly heaved herself upwards, was not helping. At all. He was vaguely aware that she called out to him, but he was too focused on the facts that, now that her brother did not chase him anymore, he laid underneath a tempting beauty. She moved a little more, making her knee and thigh hovering even closer to his groin. What had he done to deserve such punishment? She was too innocent, too sweet to actually know what she was doing to him right now. To top it all off he felt his pants tighten every few seconds. He answered her, stuttering. Again he heard her brother shout out his name, which made him shiver a little. If that guy were to find him here with his sister in this position he was not too sure what would happen.

Either Saitama would walk out the next day, hardly able to walk because the pervert would sandwich him between his sister and himself, or there would not be any remains left to be found. At all. Pushing those thoughts away and trying to forget that he was at the verge of getting one hard as hell boner, he starred into her face and concentrated on the details there. Her cute nose, glossy lips and beautiful eyes. He made a recognizing noise as he heard her whisper his name in a great distance, for the blood in his ears flowed loudly. Her delicate hand wandered from somewhere next to his head to his cheek and her innocent voice sounded again.

'Get a grip Saitama!' He berated himself, but to no avail, his body moved on his own as his slightly trembling hand wandered up her naked thigh and rested loosely on her full hips. He could feel the muscles in her grope-able ass and hip tense a little at that. Of course he had been in a few similar situations, but back then he had kept his cool, no matter what, but now... had it something to do with the fact that he had seen her in nearly all her naked glory? Suppressing a groan he could have hit himself, for his pants grew even tighter. Curse her and that ample bosom of hers.

"Sai-san? Are you alright?" She asked innocently, inertly cackling with mad laughter. Of course he was not alright, half of his face was squished under her breasts, her right hand laid on his half naked chest. His pajamas top was tangled and opened a few knots allowing her to (internally) drool over his chiseled pectorals. Oh, and her right leg was in between his while her knee hovered dangerously close to his groin. Nope, he was definitely not alright. Finally she got him. Now his usually bored look was replaced with focused brown eyes and slightly rose tainted cheeks. As his eyes focused his features turned from that of a boiled egg to a ruggedly handsome male specimen rarely seen on him these days.

"H-ha-hai." He stuttered, which came out muffled because of her bust laying over the bottom part of his face. Outside she could hear her elder brother walking by, his fake high-pitched voice shouting out Saitamas name. She felt him shiver underneath her. Why did her Aniki have to chase him through the building? Of course he was handsome, but sadly not many could see that because they got distracted by his bald head or his lax stance.

The steps of her brother went to another part of the hot-spring mansion. She let out a sigh that she hoped came off as relieved, but in truth it was in disappointment. She would have loved to mess with him a little longer, playing innocent while getting it into his brain that she actually liked him. "I think he's gone." She whispered, getting her boobs out of his face, straightening up but keeping her hand and leg where they were. Noticing with delight that his formerly monotone face was now sharp and flushed, eyes staring concentrated into her face. Luckily she had mastered the innocent mask, keeping her sly and cunning self hidden deeply.

"Everything alright, Sai-san?" She asked while tilting her wild maned head to the side. He did not answer so she put a hand on his forehead and asked: "Do you have a fever? You seem awfully flushed, Sai-san." Sadly he did not flush beyond that really handsome looking rose tainting his cheeks . 'Damn him and his control', she thought bitter while keeping a curious and worried expression. When he did not answer, still staring instead, she called out his name again.

"Sai." Nothing. "Saitama!" He blinked in rapid succession and let out a 'mmh'. 'Did I break him?' She asked herself, but internally shook her head fast to get that idea out, no he was not weak to be defeated by a woman's curves. Right? Right.

This time being really worried about him her brows knitted together in concern and her left hand, formerly laying besides his head, wandered to his cheek. "Sai?"

As if in response she felt his warm hand wandering up her tight until it reached her hip, which tensed up at the foreign contact. Making a rather embarrassing noise at the contact, she cursed herself for turning red.

Such a beautiful shade of red her face was.

But before he could do something to [Y/N] a shiver ran down his spine, he felt as if something was watching them. Waiting. A demonic aura made itself known in the room at that moment and then there he was. In the middle of a moonlight lid night he jumped, in all his naked glory high above his sister and the man that was his prey.

A high-pitched scream tore through the night, waking the living and the dead.

Ola, ye Chikorita's :D

Here is my first attempt at a Reader Fanfiction, it is vague about the Character but none the less point's out it's a she.
It was originally written to be part of a longer Story, but then I thought this would make a good One Shot, and yes, the reader is the sister of Puri-Puri Prisoner.
Sorry to the guys out there :)

Ja ne :3
