One more step

Josh continued to tap hungrily.

After every change Josh felt goosebumps or an itch crawling across his skin and his innards. According to his previous finds this app worked in the most human way. Probably a very complex metaphysical reality bending adjustment is made every time a new rule is introduced. Josh did not care any more. He already fucked human race and he was about to fuck it more and more.

The next set of rules must be thought out more thoroughly as not to irreversibly fuck up. So...

{The owner of this app is the last person that has written in it}

Enter.

Josh waited a moment pondering on his next rule.

{The owner of this app has 3 cocks}

Enter.

All of a sudden he felt that his sitting position, once again, was uncomfortable. Two more 'snakes' slithered down his pants, straining them considerably. He shifted even more, trying to find a way to accommodate those pythons.

{The owner of this app has dicks of maximum length and girth}

Enter.

Now it really became uncomfortable. It was not a matter of shifting around, but buying new cloths. Shish, he has not predicted this outcome.

{The owner of this app is always a man}

Enter.

OK next is the general change to humanity that should benefit everyone.

{Every human IQ increases exponentially with the more sexually aroused they are}

Enter.

"Fuuuuuck!" Josh thought "What the fuck is this clarity? Iam just mildly horny, but it feels like I suddenly understand everything so much more."

His brain felt like small ants crawled around. It was unpleasant at first, but this sensation quickly subsided. After that he suddenly started to see things clearer. Like a fog was lifted from his mind. He could calculate complex mathematical problems, his thought process became faster, everything seemed easier.

Josh noticed that his phone also changed. While before it was the latest model but still quiet standard, right now it became futuristic as fuck. Extremely thin, flexible to the point of being able to bend it like paper, stretchable to a size of a large tablet. Navigating to the phone settings he found out that battery was over 10 times larger than he remembered and processing power cuadrupled.

Checking Wikipedia under world history and reading at least 3 times faster than before he understood that with his latest rule he has changed human history in a very significant way.

Many more geniuses and visionaries appeared through out the timeline, introducing new tech and new ways of thinking way before 'intended'. Nowadays there was no oil powered machinery anywhere in the world. Everything ran on electricity and the means of power extraction was several fold more efficient and less harmful to the environment. All sorts of advancements were made, such as an international moon base, a colony on Mars, eradication of cancer, etc. People in general were smarter, as the general IQ increased, with significant boosts during sexual arousal.

"Jesus christ! This insane!"

However Josh still was not fully satisfied. He started this and was damned if he would stop.

{Sex is viewed as a casual, everyday activity}

Enter.

All of a sudden he started hearing noises around him. If before it was a normal everyday chatter, now it was way more lewder. Moans, flesh hitting flesh, slurping and sucking sounds.

He wanted to look, but he resisted the urge. Just like before, he did not want to spoil a surprise for himself.

Although those sounds were very enticing and rose his horniness to new levels, Josh did not waver and continued with more rules.

{All human newborn babies are randomly swamped between families}

Enter.

{All adult humans are nymphomaniacs, with hypersexual drive, but have strong willpower}

Enter.

The sounds intensified around him. More and louder moans, harder slapping and gaging sounds, voices asking to stick deeper, fuck harder, lick faster. The smells of flowers, milkshakes, fruits and nuts permeated the air in the coffee shop in a thick, almost tangible, mist.

He still did not look up but his nostrils were flaring up, trying to inhale as much as possible. His breathing became ragged and gasping, and the monsters in his pants were nearly ripping the fabric apart with how hard and sensitive the became.

Josh es willpower was tested to it limit, but he held on like a champ.

"Thank God I've added the last part in, huh?"

{All humans are asexual before 18th birthday}

Enter.

{Pornography is considered an art form}

Enter.

"C'mon man! The last change for today! Don't look up! Don't look up! Don't look up!" he repeated those words like a mantra, while introducing the last rule.

{Only an owner of this app can see this app}

Finally, he was done.

Josh raised his gaze and felt shock washing over him, for the scene in the Cafe and outside was enough to momentarily petrify his incredibly stimulated mind.
