Disclaimer : I do not own Naruto, Masashi Kishimoto does.

Warning AU : Graduation is at 18 so everyone involved in smut are all above 18. Also, Kushina and Mikoto survived for obvious reasons.

Is this purely smut? Mostly, yes. There is still action and fights because, why not?

Its a smut/action fic after all.

Anyway, this is rated M for smut, may also contain some swearing and gore.

This does not contain : Rape content (physical or mental), NTR or underage sex. Everything will be purely consensual. There is also no incest or gender bend.

This contains : Anal, gangbang (Shadow Clones), huge genital size, intense orgasms and any other consensual kinky stuff. It also contains sub/dom content and fucked silly.

Is it a Harem story ? I don't know. Maybe it will, maybe it won't but the MC sure is gonna fool around with a lot of women.

Also, this is not a reincarnation fic. It's about an orphan of a Civilian family that will rise to the position of the strongest man of Naruto's world through a smut-gamer. Those abilities will become OP too.

Finally, this is just a fanfiction. None of this represents reality. I am not a professional writer. I just write for fun and for your entertainment. Let's keep it light and fun !

My warning being said, don't forget to fav and comment on this story !

I hope you enjoy it !


Chapter 1 : The debut of the Ero-Choice-Gamer.

Daiki Mori was nothing but a clanless orphan.

It had always been like this.

He had scored in the middle of the class at the Academy.

He got recently promoted to Chunin after a year of service because of some technicalities on a mission.

His skills? He could walk on water and trees, throw Kunais well, had a decent amount of speed and overall physical attributes for a Chunin and -

Well, that's it actually.

Nothing more, nothing less.

He was the perfect example of your average Chunin.

Sometimes he felt like he didn't even merit the rank of Chunin but, here he was, leading squads of Genins to C-ranked missions from time to time or goes to solo border patrol missions.

Everything seemed to be dull in his life.

Until it happened.

Daiki should have been dead, he really should have.

He had been ganged up by a squad of Iwa-nins in the night when no one saw them coming.

Two Jonins and Five Chunins.

He got his jugular slashed before he could even scream a shout of warning for the others.

He should have been dead.

But he wasn't.

He was looking at the strange blue screen that was floating in the air.

Do you want to play the Ero-Choice-Gamer?

Yes / No ?

Now, Daiki was overall average in most things but he wasn't stupid.

No sane human should trust some floating blue screen.

But he was already dying so what was the point in not trying ?

Shakily, he brought his left hand's index to the 'Yes', and the screen disappeared.

For a moment, Daiki thought he had just seen a trick of his mind before death and he started to panic.

Until it came back.

Welcome !

Please wait for the end of initialization : 1%

And then he saw nothing.

XXXX

Welcome !

Thanks for your patience. Do you wish to start the tutorial ?

Yes / No ?

It felt surreal, even as he was absently answering the medic-nin's questions, it felt like a dream.

But honestly, at that point in his life, he didn't care anymore.

He was average in all senses.

He barely passed anything he did, mostly because of his laziness and unwillingness of trying harder.

He got one girlfriend, that he got together for a month before she dumped his ass after she saw how average he was.

She was his first, and also, the last girl he had sex with.

He was an orphan.

He got no social life.

No money or power.

No friendship.

No nothing.

So when the blue screen popped-up, he was way too far in the deep to care about it.

He pressed 'Yes' mentally, something he discovered painfully when the medic-nin that was surveying him saw him point at invisible things in the air.

It never occurred to him at first that this screen was only available to him.

Welcome to the Tutorial !

This system is designed by ?, in order to entertain him and his audience. Through sexual intercourses, you will gain power according to the people you had sex with

Penetrating them will give you two choices to choose from. Each choice has one ability that is proper to the women you bed. The ability can be something she already has or something she will excel in later on. It can also be a bloodline, that she has access or not on but that will affect the foreknowledge of the skill you will have after acquiring it.

As a bonus to start your journey, you may find a : Engorgement Pill in your inventory.

Good luck !

It was a lot to take in.

He breathed a sigh of relief as no other text appeared.

Ero-Choice-Gamer huh?

Couldn't hurt to try.

What else could he do anyway? Go back to patrol?

Heh.

As the medic-nin finally let him alone, he opened the Inventory he got from this system.

Welcome to the Ero-Choice-Gamer : Inventory

Items : Engorgement Pill

He got it out of his inventory with a flick of his wrist and examined it with the system.

Engorgement Pill : It will thicken and enlarge your penis to the highest degree. After that, pornstars will blush at the sight of your pole. You will have the biggest dick of this universe.

Assimilation Time : 6 hours

What the -

He took a deep breath.

It was written in the title « Ero-Choice-Gamer ».

Of course it was all about sex.

Not that he minded one bit.

What sane man would refuse something like that ?

Without any regret and consideration for any nasty side effects, he took the pill and swallowed it.

He looked at his body, checking for any abnormality.

He smiled, nothing horr -

He lost his smile a second later.

The pain.

He withered at the sharp pain that was coursing through his shaft.

The pill sure was taking effects immediately.

But it would be a pain in the ass to go through that.

But Daiki didn't care.

He didn't care about the pain or the weirdness of this.

Or even about who was the guy, or whoever created this system.

All he cares about is the fact that, for the first time in his life, something unique happened to him.

And he was all for it.

XXXX

Those past six hours had been, weird to say the least.

At first, the pain had been unbearable. After a moment, it became a weird sensation coursing through his shaft.

And now, looking at his cock, it was everything but average.

The pill was no joke. He may really have the biggest and thickest dick of this world.

We swung it from left to right, having no small amount of fun doing so.

He sighed, getting his attire back on him and got out of his crappy place.

But, it wasn't the strangest thing.

The fact that it even worked was weird.

The fact that system was real was weird.

Questions upon questions appeared in his mind but no answer came to him.

Who created this ?

Why was he chosen ?

Why should he do about it ?

He only knew that trusting this thing entirely was stupid but it may be the only way to become stronger and stop being average.

He would be careful but won't back down from using it.

Getting stronger by having sex ? Who would say no to that ?

Yes, he was already a pervert - and he was a healthy young man, but even a monk would think twice before not using it.

« Daiki ? » A voice said behind him, which prompted him to look back.

A strange sensation rushed him as he looked at who it was.

She had short pink hair, a red and white qipao hugging her athletic figure and green vivid eyes staring at him with wonder.

He remembered her. She was Sakura Haruno, the daughter of his deceased parent's friends.

He never really interacted much with her to be honest. She always was too loud and obnoxious to be honest.

But now he had a better look at her entrancing body, he stealthily licked his lips.

I put a smile on my face, taking her in a sweet and surprising hug.

She hugged me back, putting her head on the crook of my neck.

I might have thought she was annoying, but we still were close enough.

I looked down and got shocked to the core.

Damn she might have lacked in the boob department, but she was packing whole bag of firm ices behind.

I put my hands on her hips, eliciting a surprised yelp but I made it look like it was just a friendly hug.

It was stupid of her to think that, but she did relax.

Nice.

I backed up a bit to look at her in the eyes, while never letting her go from my embrace.

She seemed to notice, a faint blush appearing on her face.

Progess is progress.

« How are you doing ? You made as a Ninja ! I can see your headband. Congratulations by the way ! » I said in a happy tone, which wasn't faked. I really was happy for her.

She blushed, a small pout on her face « Yeah I am all grown up now ! » Her face contorted in a dreamy tone « I can marry Sasuke now ! »

That made Daiki backpedal instantly.

Sasuke Uchiha.

He needs to be way stronger than him to have any kind of chance to bed Sakura.

If he can't beat that guy, he might never be enough in her eyes.

But he didn't want to fight him. Despite both of them being ninjas, it would be petty of him to just provoke the fresh out of Academy Genin and broke his face in two to prove his point.

Moreover, there is a big possibility that he might get his ass whooped by that guy.

He was a hell of a ninja.

No, Daiki need to become stronger before he could have her.

Now that he thinks about it, most hot babes would require him to be strong.

Stupidly strong.

He needs to be the strongest man alive so that he can bed the strongest and hottest girl in this world.

Which, in turn, will give him more power.

His goals now set, he smiled at her apologetically « That's nice. We will have to catch up later though. I need to go on a mission »

She nodded, a happy smile on her face as she waved at him « Alright, see you soon ! »

Daiki waved back until he got out of her sight.

He needs to gain those said rewards in order to get stronger fast.

Who better than his ex-girlfriend?

XXXX

Sayuri was having a strange day.

First, she started to think about her first boyfriend, Daiki, throughout the day.

That never happened before. Not when she dumped his ass or even when she had been with him. She accepted to date him just for some quick fun at that time.

He had been so shy and awkward that it made it cute.

Honestly, they both had been shy at that time but, even though it was adorable at first, being constantly like that made it all boring.

But now that she was all alone, after her stupid cheating boyfriend was gone, she started to think about him again.

But it wasn't the weirdest thing that happened.

He came back. Well, not really, they just happened to meet in the street, but it was as good as coming back.

She didn't drink before this, she was just going out to do just that, and she met him on the way.

They talked pretty much about everything that they did during their separation.

Something was odd with him. He was always the confident type in general, but something changed in him.

She could sense it, and she like it very much.

She might have fun tonight after all.

Sayuri wasn't a slut. She had two boyfriends in her lifetime. The first being Daiki and the other being that mofo that cheater on her.

She is a Chunin of Konoha, and she didn't want to be pegged as a slut in the ranks.

Not that she would act like one. Even though she liked to have fun, she wasn't the type to fuck with anyone just for the sake of doing it.

"So, what do you think?" Daiki was already pinning her against the wall of her apartment.

How and why did they get there, she didn't know, but she was happy to comply.

"Show me what you've got since then" She said testily and he just smiled, inviting her to try.

She did exactly that.

She knelt down in front of him.

And pulled down his pants and boxer in one swift motion.

SLAP.

What. The. Heck.

Now Sayuri was wondering if she was drunk.

Because there was no way this thing was attached to a skinny guy like Daiki.

He was always above average, from what she remembered.

But that thing ?

No wonder he got cocky, rightfully so.

She licked her lips. That will prove to be interesting.

She always liked Daiki but he was being too meek to maintain anything but boring with him.

Now, things have changed.

She didn't wait anymore.

XXXX

Daiki was having one hell of a day.

First, he almost died.

Then, he got a weird system that forced him to have sex with other people to gain power.

Well, 'forced' was a stretch when he was all too happy to oblige.

Then he got the hugest and thickest dick this world has just by a pill.

And finally, he met his ex-girlfriend before she entered a bar.

And she was now slurping on his cock like a bitch in heat.

Man, that was good.

He took a handful of her purple hair, forcing her to let out his cock out of her mouth.

It wasn't the time for that.

He threw her on the bed, eliciting a cry of surprise and joy, as he climbed on top of her.

He aligned his shaft to her entrance, but he started to lube her pussy with his fingers before doing so.

There was no way that thing would be able to enter that tiny hole without doing some damage.

He bent on his knee, and started to lick her pussy.

He wasn't good, and it showed, but Sayuri was all too happy to show him how to do it.

"Not there … Yes ! Just there ! Lick it, now rubs down there and – and – OHH ! OHHHH !" She started to whither and I couldn't help but get a little bit cocky.

I thrusted a second finger and she exploded right on the spot !

"AHHHHH ! YESSSS !" She shouted out loud as squirts of women semen exploded all around the room.

Damn that was hot.

I let her take a breath, kissing her on the lips as I massaged her flat belly with my right hand soothingly while caressing her left boob with my left one.

She always had ample tits and a huge pair of asses. I loved her body so much.

As I looked at her purple eyes, eyes that complimented her hair, I smiled.

"Time for the real thing" I said with a smile as I took the position again.

She was getting more anxious as I approached her and I took a second to kiss her again.

"Please, go gentle" She said and I nodded immediately.

I wasn't an asshole.

A part of me wanted to just do that, but I knew it was petty so I decided to honor her wish.

As I slowly entered, eliciting an hiss from her, the world around me froze.

I panicked, as I too, couldn't buldge an inch.

I looked around, everything was normal, except that even the birds in the sky were frozen.

A pop-up appeared, the pop-up divided in two boxes.

Reward :

Choose from those two gifts.

Fire Affinity (Intermediaire) / Genjutsu skills (Intermediaire) ?

Well, shit.


What do we think about this chapter ?

Love it ? Hate it ? Doesn't makes sense ?

I know the engorgement pill is kind of a shitty move but it's a smut-fic with some action. Did you expect something else ?
