'Hmmm, though there aren't any interesting books here, I might as well buy something since I've come this far.'

Thinking that he should buy something from the second hand bookstore, Kazuma Yagami kept on looking through all the available books. But regardless of how many he saw none of them were interesting in the least.

"Boy, are you going to buy something or not? I'm going to close the shop in 5 more minutes, make sure you've chosen something by then."

Hearing the shopkeeper's words, Kazuma saw that the time was just 5 minutes less of 7. Just as Kazuma was about to choose something or the other, his eyes darted towards a black colored book that was buried under relatively older looking books.

Stepping close to it, Kazuma carefully pulled the book out. The book despite being in a second hand store had a qaukoty book cover on it, which felt smooth and comfortable.

Turning the first page, Kazuma saw the words - Obscene System V 2.0 written on it.

'The Obscene System? Hahaha, it must be some erotic novel. I might as well choose this.'

Making his choice Kazuma bought the book without any hesitation and left the shop. By the time he was back home it was already 7:30, and his mother had already prepared the dinner but was nowhere to be found.

Thinking that she was in the shower, Kazuma sat down at the dining table so that they could start eating when she would come back.

With nothing else to do other than wait, Kazuma flipped the book open.

Going into the second page he saw the words - Write your name.

Feeling bored, Kazuma decided to just go with it.

[Name - Kazuma Yagami]

[Age - 15]

[Gender - Male]

[What Obscene Fantasy would you want to trun into reality? - Being able to do whatever I want with any and every woman]

[In what form would you like the system to be in. Mobile, Computer or Watch? - Mobile]

[Your Obscene Fantasy has passed the required level. The Obscene System V 2.0 will now turn on.]

As soon as Kazuma finished reading the text, the book brightly shined and by the time the light dissapeared in its place was now a 6" screen size Mobile.

By its appearance itself it didn't look any different from the touch screen phones available everywhere, but it was due to a book turning into a phone that Kazuma was shocked out of his wits not knowing what to do.

Just then the screen on the black phone lit up.

<Hello, Kazuma! We wish you to have a pleasant experience with the Obscene System V 2.0. Anything you enter into the mobile will turn into reality! There are no limits other than your imagination! Enjoy!>

Looking at all of this the first instinct of Kazuma was to run! He didn't care if it was real or a prank, he just wanted to run away. But somehow as if he was under the influence of the Devils whisper, his hand as if it had a mind of its went ahead and picked up the device.

The screen despite being lit up was completely blank, other than a keyboard to type with.

<Can I ask for anything?>

Kazuma typed in somehow with his still nervous fingers which were hitting the wrong keys causing him to erase and type in again. But due to this he realized that pressing the enter key on the keyboard was compulsory for the question to be registered.

<Yes.>

<I want to grow taller, and become handsome! I also want a bigger dick!>

Despite seeming wierd, they were the first things that popped into Kazuma's head. If he could only get one wish, then these were the ones he wanted the most.

<How tall do you want to be, how handsome, and how big should your dick be?>

<Make my height 6 feet, I want to be so handsome that all women would blush from seeing me, and make my dick 10 inches. Also give me a six pack, and some strong muscles.>

Who knows if it would really come true, but if it would indeed work, it's best to go all in right?

After Kazuma finished typing in, the black mobile in his hand shone soon after which he could literally feel his body changing. However weirdly he didn't feel any pain, and everything felt like it was naturally.

Rushing to his feet Kazuma ran up to his room, and looked into the mirror. Looking in he was shocked at how much he had transformed.

Before he used to be a measly 5 feet 6 inch tall boy, who had an above average face that was filled with pimples. But now he was a 6 feet boy with strong muscles, a chick attracting 6 pack, and a face which he only saw idols having.

Now even the clothes he was wearing were tight and would rip if he tried to move too much.

Before the happiness of what happened could set in, Kazuma felt afraid that what would happen from now on!

He had changed so much in a single day, that not even his own mother would be able to recognize him! What would happen when the government found out about him, would he be cut open by wierd scientists inside a secret research facility?!

<Now that I've changed so much, won't everyone find it wierd?>

<No, everything changed through the Obscene System V 2.0 will make everyone think that it is completely natural, and won't doubt anything about it.>

Oh! Shocked and happy at how useful the black mobile is his hand was, Kazuma tried to probe more into it.

<If I make it so that all women on Earth never wear any clothes, no one would find it wierd?>

<No, even if you asked for all men to be killed. Not a single woman would doubt anything that would happen.>

<Does that mean I could change the whole world? In that case could I go into fictional worlds of Anime as well???>

<Of course.>

By now Kazuma was already on cloud 9. It seems like the God of Fap had been pleased by how many times he sacrificed his previous seed, and so decided to gift him an omnipotent gift!

'Calm down, calm down. If I start with the best things right away, the story would be finished way too soon. I should enjoy this to the limits by going from the smallest things. Let's start with her...'
