The next two days passed in a blur, my spirit coins rising precipitously as I lent further and further into the depraved pleasures of the flesh.
After leaving the bathroom, my urge to fuck had reached new heights, and I prowled around looking for my new partner.
It took longer than expected to find someone willing to have sex, but I eventually spotted a skinny, younger man nervously bouncing his leg near the stairway leading to the zombie-infested surface. His eyes had a faraway look, and he was constantly gripping the hilt of his sword, a weapon he had clearly bought from the system shop.
"You look stressed. I can help you with that if you want. You know, release some pressure." I asked him in a sultry tone, doing my best to show off my fairly curvy body as I winked at him.
The man's face scrunched up, and he seemed to be about to tell me to get lost when he suddenly froze, looked around himself, and seemed to consider his situation before releasing a long sigh and taking a good look at me, his eyes drifting down my body, stopping on my plump breasts before slipping down to my thick but firm ass.
"Alright, I would enjoy releasing some stress with you." He replied, grinning as he got up, walking around the corner and out of sight, beckoning me to follow.
My pussy was already leaking as I took my panties off and bent down, getting on my hands and knees and wiggling my naked rear at the man. He seemed to be frantic and jumpy, even now as he took off his own pants and revealed a much smaller cock than the other guy, shoving it into my vagina with a single thrust, my hole already so wet and gaping that I barely felt him inside.
This session was brief and energetic on his part as he humped my pussy like a dog, his movements fast and shallow as he wheezed and panted to himself, using me like some sort of masturbatory aid, the man not even touching the rest of my body or making any attempt to make me feel good. It was then that I realized he might actually be an inexperienced virgin. That thought sent chills down my spine, like I was tasting a forbidden fruit in making his first be with a newly awakened slut like me, who simply wanted to use him for my own gain. He was certainly far younger than the tough man from the bathroom and couldn't be older than 18, his fairly wiry frame and nervous attitude lending credence to the idea.
But despite the cute and almost endearing situation, like I was turning a child into a man, I instantly knew the moment he was about to cum as his breath started coming faster and he made a strange strangled noise.
I had been fairly amused by the whole thing. The novelty of the experience overshadowed my unsatisfied sexual frustration, but I was too slow to react when I felt him ejaculating atop me. I was so horny that I didn't even feel when he took out his small dick, yet the only way I could get spirit coins was if he came inside of me; pulling out was actually a really bad thing for me, but I forgot to mention it before.
In a panic, I quickly tried to push him back inside of me, but he simply fell over, his legs weak while ejaculating as his sticky white semen splattered onto my ass and back.
Slightly panicked at the wasted sperm, I first tried to gather the cum from my body and push it inside of my pussy, but I couldn't get enough of it inside, some of it dropping onto the ground from how wet and slippery my vagina felt.
Out of options, I didn't even think, as I instead licked my cum-covered fingers, reflexively swallowing the smelly cum before I even knew what I was doing.
Yet before I could chastise myself for the disgusting act, I noticed my spirit coins increased slightly. It was only by two, so hardly the massive amount I gained from the first creampie, but I proceeded to scrape off and eat all the cum he produced, swallowing it all to be converted into spirit coins.
After that, I realized I didn't actually need to have sex to gain more points, simply consume their cum in any capacity. I didn't even taste it in my mouth for long, as it almost instantly disappeared when my skill activated. With this new discovery, I decided to simply give blowjobs to those with smaller dicks while receiving creampies from the true studs like the first thug.
Since they often spent a lot of time fighting the zombies outside, I was only able to find a few of the men at a time; many women were also fighting above ground, so the pool of people willing to have sex with me was actually fairly limited.
It was after letting a middle-aged man with a crooked dick fuck my face and jizz down my throat that I finally gained enough points to buy a new skill. I choked and gagged as his thick semen flooded my throat, the man's cruel smile sending shivers down my spine as he finally let go of my hair, having forced himself down my throat to the point I thought I was going to pass out. Still, the stinky cum quickly cleared from my airways as my skill did its job and I rested, looking over the system window.
It had taken several sessions to acquire enough points; the amount of spirit points I got varied wildly depending on the person, but unfortunately, none of them provided the same amount as that thug from the bathroom. Still, now that I had finally gotten over 200 points, I opened the system shop and looked over my options.
Available skills (Each 200 points):
Lustful hypnosis (C-rank): Lull a target into obeying you. Effect based on target arousal and willpower. Barrier (E-rank): Form a protective dome around yourself that lasts for up to a minute. Beserkers' passion (B-rank): Inflect a maddening effect on your sexual partner that multiplies their lust and sperm count.
Or spend 200 points to upgrade:
Semen conversion (B-rank) --> Lust extraction (A-rank): Extract spirit energy from sexual intercourse. Gain more spirit coins from semen, while also gradually extracting targets' spirit energy to form more coins during intercourse.
I was tempted to get a skill to help me get more semen, like berserker passion, as it would mean I could get that thug to fuck me for far longer and fill me with even more of his amazing cum, but in the end, upgrading my original skill was the best option.
I didn't feel any different, but I was keen to test it out. The ability to get spirit coins for the entirety of time I have sex is already a huge upgrade, so now I just need to find that thug again.
Soon enough, I'll be rich... And a complete whore.
