It happened one day while I was out shopping: a massive earthquake that shook the supermarket. The sound of screams and falling buildings had made me cower under a table when something decidedly different happened. Earthquakes were very rare where I lived, this being the first one I had ever experienced in my twenty years on this Earth, but I knew something was off when a strange blue screen appeared in my sight.
Welcome to the cosmic games!
Your world has the honor of being chosen to participate in the cosmic games. A randomly selected theme will apply to test your fortitude and resolve in the face of difficult situations. But fear not, for you shall all be granted the ability to awaken your dormant spirit power, abilities ranging from F to S rank that may grant you unimaginable powers.
Your scenario has been selected as a Zombie apocalypse. During this scenario, all low spirit denizens will be turned into undead and attack the living; only those who successfully awaken spirit powers will be spared. The survivors must slay the undead to earn spirit coins, then spend those coins in the system shop to purchase anything from weapons, spirit power upgrades, or even new spirit powers.
Good luck, and may your struggle impress the gods.
This message was seen by everyone all around the world, and for many, it was the last thing they ever saw. True to the message's word, two-thirds of the world's population transformed into mindless undead and began attacking the living, a true zombie apocalypse.
I was lucky enough to awaken a spirit power, a fairly high-ranking one at that, although it wasn't anything like I was imagining.
Congratulations, you have awakened the prostitute type skill, Semen conversion (B rank)
Your body automatically converts all semen into spirit coins. This skill's effectiveness depends on the quality and quantity of the semen, but it also means pregnancy is impossible.
I had been utterly shocked at the skill's description. I was never a very sexually active person; in fact, I had only had sex a few times in my life before my boyfriend cheated on me. So as other people began summoning fireballs and lighting, I was forced to flee the apocalyptic streets and took refuge in the subway, where the police had established a checkpoint.
A few hundred of us lived down their for the next few days as explosions and fighting rocked the surface, the undead being fought back not with guns and explosives, but primaraly with skills as it was the only way to gain spirit coins from the kills, using modern weaponry would actually cost spirit coins and make it impossible for the person to upgrade their skill or purchase another.
The system shop offered three skills available for purchase for each individual, but any skill could be bought with enough points. I had pointedly refused to use my ridiculous prostitution skill to increase my coins and nor did I want to go fight zombies, so I waited for the world to return to normal for those three days. Until the food ran out.
A large fight broke out as food stores ran dry and people demanded that the police and volunteer fighters use their spirit coins to buy more food from the system shop. Many complied, but others refused, saying that giving away spirit coins for others would be suicidal as they need them to purchase new gear and weapons, not to mention feed themselves.
After the fight, things changed, and every able man was sent to fight the zombies to earn their own spirit coins, while the women without combat skills like me were left underground. A day later, and over half had died, many others refusing to go back out there. Even the police that had set up this zone had mostly all died, leaving a group of tough and capable men in charge, although it soon became apparent that these men were actually closer to gangsters as they forced the others to give them most of their spirit coins as payment for keeping them safe.
It was true that they were strong, but mainly because they took the coins from the rest of the fighters, and it was even rumored that they had killed some of the police officers to steal their spirit coins.
It was on the sixth day that things changed for me. I had barely eaten anything for the last few days and went to the bathroom to get a drink when I heard a woman cry quietly. Thinking it was strange, I silently made my way past the line of stalls and found a man and a woman.
It was one of the gangsters who had slowly taken control of the shelter, and he was molesting a crying woman, his hand down the front of her pants as he sucked her exposed breasts.
The woman clearly wasn't enjoying herself as her eyes watered, but before I could reveal myself and stop him, the man spoke to the crying woman.
"Why are you acting all sad? I said I would give you some food if you helped me relieve some stress. If you're not going to help the group fight back against the zombies, then you at least need to prove your worth in other ways. Don't worry, from now on all you bitchs will be using your bodies to pay us back." He said harshly, grabbing her cheeks as he ripped down her pants and exposed her shaved pussy.
His words froze me in place, and I just watched as the man fingered her while unbuckling his own pants. But I wasn't frozen in fear at hearing all the others would now force the women to have sex for food, but rather at the idea of how that would work with my skill. I had refused to even think about it until now, but if having sex gives me spirit coins while also being given food by the men, then wouldn't I be able to make a lot more coins than even the fighters and be given new skills from the shop?
Sure, it wouldn't be pleasant having sex with a bunch of gangsters and street thugs, but it would only be a temporary inconvenience on my path to growing stronger than all of them. The world had changed, after all, and I had to change along with it.
"Hey, I don't think she likes it. Why don't you play with me instead?" I said, revealing myself as I walked over to them, swaying my hips sensually.
"Oh, we have a naughty whore down here, do we? Fine then, come here, I'll have you instead." The man said, releasing the tearful woman and turning to me with his pants down and his erect penis exposed. It was larger than I expected, and I honestly felt a bit of anticipation at taking such a large thing inside of me, my previous boyfriend having been on the smaller side.
"Don't worry, we can split the rations," I told the woman as I pulled down my own pants and turned around, sticking my butt out towards him, not wanting to engage in pointless foreplay. The faster he finishes, the sooner I will get her coins.
"Oh, you want me to put it in dry?" The man asked, chuckling to himself as he grabbed me from behind and placed the tip of his cock at the mouth of my pussy and pushed himself inside.
It stung a little, but I honestly felt kinda wet at the idea of taking all those men despite myself, the prostitution skill meaning the rewards I get for sex make it a far greater proposition than ever before.
With the partially nude woman still standing in the bathroom and watching us with wide eyes, the man rammed into me with ferocious force, his dick reaching deep inside of me and making me scream and moan with each thrust, the intensity of it far beyond anything I had ever experienced before. He pinned my arms behind my back and humpped my pussy against the bathrrom wall, my legs shaking as he reached deeper with every thrust, his penis hitting places within my body that I had never even known about, waves of mind numbing pleasure rushing into my me as he accelerated, until his dick was thurst deep inside of me and stayed, his cock pulsing and expanding as he delivered his huge load inside of me, the man clearly not having had a release in a while as semen flooded my belly, I could feel its warm stickyness inside my womb.
But when he pulled out after releasing his load, his cock exited without any sign of cum, his dick sparkingly clean and only covered with my pussy juices. He smiled at me and slapped my naked butt before staring off into space for a few seconds. When his eyes refocused, two military rations appeared in his hands, and he gave them to me and the woman, thanking me for the enjoyable time, and walked out with a spring in his step.
But I was focused on the message that had appeared moments after he had finished cumming.
As a result of Semen conversion (Rank B), You have gained 50 spirit coins
I stared at that message for a few long seconds before a smile formed on my face. Killing a zombie costs only a single spirit coin, so having sex is the equivalent of killing fifty zombies. I looked at the prices for a new skill in the system shop. The three skills that are most compatible with me and are available for purchase at a lower than average price are all two hundred spirit coins each. It looks like I'll need to fuck a few more guys.
Touching my now gaping pussy, I found that no cum is leaking out due to my skills' effects. I guess I don't even need to clean up after a session, either. And for some reason, I feel realy horny after taking that guy's dick. I had thought that the skill I got was a mistake or just assigned randomly, but could I actually be a massive whore and simply hadn't had the opportunity to discover it until now? I blame my ex's pathetic dick.
Oh well, time to get laid in a zombie apocalypse and become rich enough to buy every skill I can.
