Losing Levels to a Slime

I cursed as the barrage of acid sprayed around the edges of my shield, small bits of the spray corroding at the skin on my legs. Fuck, I wasn't able to block it all. I quickly retreated around the corner of the doorframe, downing a small healing potion before attempting to reconsider my strategy.

Even for the great chosen hero of the human kingdom, the last bastion of hope against the impending tyrannical rule of the demon king, a witch of this caliber was no easy fight. These witches were greatly feared across many races, not just the humans, for their seemingly sadistic enjoyment of magical experimentation. The last time I had fought a witch this close to the demon king's castle, the twelve humans in her dungeon had already perished when I finally defeated her. I shuddered at the memory of their disfigured, scarred bodies.

I would not let it happen again. Could not. I held up my sword, staring at my reflection, the beads of sweat dripping down my dirt-smeared face. I grimaced as I wiped the acid from its edge. At least the magic that kept my sword in perfect condition, a gift from the queen herself for my journey, was still holding up.

I took a deep breath, glancing once around the edge of the doorframe only to barely dodge back as another bottle of who knows what magical effect went whirling past my cheek. Normally it would take a small brigade of soldiers to raid a witch's dungeon like this. But this was my third one today. The trick was to get in close, something that was almost impossible with a large number of party members, which is why I took adventures like this alone. Not to mention that anyone else would just get in my way.

As the chosen hero, I was born with the amazing ability to level at ten times the standard rate, greatly increasing my speed, strength, reaction, and stamina over that of a normal human. But all of the combat skills I had gained were my own. I checked my level as I uncorked another health potion, holding the lip of the vial between my teeth. 542. The witch's had been somewhere around 350-400, judging on how fast she was able to throw that bottle at me. And given the size of the room at about 20 feet... I nodded to myself, half stepping into the doorway before turning back immediately, watching as the bottle careens into the hall once more, this time exploding with hellflame against the stone wall.

But I didn't stop to stare, immediately committing into the room at a full sprint. I blocked the next attack with my shield, before swinging it towards my feet and rolling over it. I was so close. Halfway across the room. But the next bottle was faster than I expected, splashing acid across my body. I howled in pain as it ate away at my armor and leather gear, but managed to down the potion of healing I had held in my mouth just in case, healing my wounds just enough for me to be able to lift my sword- and lop her head off in one clean cut.

I breathed a heavy sigh of relief, downing another potion to fix up what the first one couldn't. I bit my lip as I pushed myself to my feet. If only it could take away all the pain and fatigue too. But I didn't have time to worry about that. I had to find out if there were any experimentations going on. I shuddered at the thought of finding more humans like I had before. I wondered now if it was better if they were dead, that if there were more down here, if I should put them out of their misery.

I shook the thought out of my head, trudging past the witch's corpse collapsed on the floor as I headed down the dark stone staircase behind her. Luckily, the entire way had been illuminated by the same hellflame she had tried to kill me with earlier, so I was able to keep both my shield and sword up as I walked down the narrow steps. Finally, the stairs opened up the larger dungeon below, the sound of bubbling cauldrons all but drowning out the small cry that I heard.

"Help... help me..." I immediately rushed towards the sound, cutting off the lock on the cell door it was echoing from. But there was no one there.

"Help... oh thank the gods.. thank you..." The voice was practically sobbing, and only then did I realize where it was coming from. Down below my feet was a small slime, barely a foot tall, the small slits on its otherwise ovular body were leaking with tears. I set down my sword and shield against the edge of the cell door, gently bending over to pick it up. I looked at it closer, trying to see if there were any obvious effects from whatever the witch had done to it. But all I could see was the slightly translucent white orb, the source of its life force, inside of it.

Slimes were interesting creatures. They were monsters, their kings and queens allied with the demon lord, but the majority of them were harmless. Even the higher level ones that one could encounter around the human kingdom were rarely above level 5, and were easily killed by just crushing the life orb inside of them.

So what was a witch doing with this one? It wasn't high level, as that was easy to ascertain by their size. The great slime king, who was over level 2000, was about the size of a small house, his massive body making it almost impossible to reach his life orb without being entirely consumed. But this one was barely larger than my head, it couldn't have been more than level 2 or 3.

Still, it was weird to hear one speak. It was known they could speak the common tongue, but I had never heard one do so before. At the very least I could ascertain some information from her, even though it did seem a bit cruel after all she had been through. I decided it was worth a shot, to at least attempt to learn what the witch had been experimenting with. It could be invaluable research. So I sat down, holding the slime gently in my lap, doing my best to maintain eye contact with it as I began to slowly pet its head, attempting to soothe the small monster enough that we could talk.

"It's okay... you're safe now... I won't hurt you..." I promised, speaking slow and quiet as the slime's gooey tears wet my pants, or what remained of them after the acid. "Do you have a name?" I asked. It would be best to start slow, with easy questions.

It was almost a minute before she answered, an unintelligible mix of sounds no human could make, followed by, "but in common, you can call me Mae." She finished. I smiled softly, relieved I wouldn't have to try to copy that back to her. "So Mae, are you in pain, any immediate injuries?" The slime swiveled back and forth between my hands, registering what I assume was slime equivalent to shaking her head. "Can you tell me your name, sir?"

"Good- I'm Will.." I took a deep breath before preparing a much harder question. "Can you tell me what that witch did to you?" I asked, setting her back down as I stood up and took off my pack of supplies, strapping my sword and shield onto the back. If no monsters had come for me by now, there wouldn't be any for a while. I pulled my rations out of my pack, and began to eat as she explained her life as the witch's prisoner.

She had been left alone for over 5 years down here, barely able to keep herself sane through the solitary alone. But she had no insight on what the witch had been scheming, only that she had been fed countless magical potions of various colors and tastes over the years, but had no idea what the effect on her body had been. I wrote down what I could take from it before tossing her the rest of my meal, watching as it dissolved within the shiny blue blob of her body.

I rolled out my travel sleeping mat before shutting the door of the cell, leaning my pack against the edge of the doorframe so that if any monster did try to get in, I could hear it first. I looked over to Mae as I laid down. She seemed harmless. And at least genuinely grateful for my help, so I had very few reservations in sharing the room with her. At the very least, a slime of her level wouldn't be able to eat me fast enough without waking me first. My only regret was not taking her out of the prison she had been locked in for so long, but it was easily the safest place in these dangerous lands for us to spend the night before I could take her out to the slime kingdom. Saving her should at least provide me some safety in their lands while I traveled.

"Good night, Mae." I murmured as I closed my eyes. It had been an exhausting day of adventuring, and it only took a minute before I drifted off to sleep.

I tossed and turned as I slowly woke to the weirdest of sensations. Really, it was the most pleasurable thing I could ever imagine, so much so that I was still convinced I was asleep, having some sort of crazy wet dream. It was a side effect of adventuring alone, but at least whenever I returned home, there were swarms of beautiful women willing to take care of my pent up needs. But this... this feeling was a hundred times better than that.

I opened my eyes, struggling to adjust to the flickering lighting of the purple hellflames, until I finally saw what was going on. The last remains of my acid torn pants had been completely dissolved, exposing my fully hard 8 inch cock. But I couldn't feel the stale air of the cell on my member, no, the entire thing was completely encased inside of Mae, so large inside her that my tip was poking against her life orb. "M..Mae..?"

But it was hard to even ask what was going on, much less why, with this divine feeling on every inch of my throbbing cock. "Will! I'm sorry, I just... I wanted to show you my gratitude, to repay you in some way- I just felt an urge to do this when I saw your, uh, your member sticking out." I could practically hear the blush in her voice despite the fact that she was currently... well, I don't really know what to call it. It was like she was digesting my cock without hurting it, like the consistency of a gelatinous tongue constantly pulsing with pressure around every inch of it.

"Right..." I was still in a stupor. At the age of 25, a legendary adventurer who had been exploring the world for more than a decade, this was the first time I had ever experienced anything even close to this. Of course I had heard of some races, even humans, capturing others and using them as sex slaves, but I had never heard of a slime being fucked like this.

"M-Mae... if you don't stop now, fuck, I'm, I'm going to cum-" She didn't stop, instead the sensation began happening faster, like if a tight pussy was starting to constrict in on my cock over and over again until finally-

I clenched my fists, my head falling back as I thrust up my hips into the air. Days of pent up cum spent in one orgasm, it burst forth through the body of the slime. I watched as ropes of warm goo shot up through her body, a foot into the air, then back down onto her, where it was slowly absorbed and dissolved. She's eating it, I realized. Her pale blue form was supplemented by milky white swirls as she slowly consumed it all.

I fell back, letting my hips fall back onto my mat as I tried to catch my breath.

"Oh my.. holy fuck, Mae..." I was practically shaking, lightheaded from the euphoria of it. I felt drained, weakened from the orgasm, but not in the usual way. In fact, I realized as I sat up to look down at the slime encasing my crotch, I was still hard, my cock completely cleaned of cum and ready for another round.

How was that possible? I had never fucked a slime before, I guess, maybe it was something to do with her. "Can we go again, Will?" Her voice was excited, almost elated, as if she had received more pleasure from it than I had. "I- I don't know why, but your cum... it tasted sooo good! Can I have some more?" Her voice... it was louder, fuller than before, and it wasn't just from her mood. I realized then that my cock was no longer reaching up into her center where her life orb resided.

"Mae.. did you level up from that? Slimes don't level up from having sex normally, do they?" She gasped. "You're right! I'm up to level 22! maybe that's what the witch did to me! Why I want to fuck so bad!" I tried to sit back and think. Some sort of potion.. allowing one to level up from sexual activity? That seemed almost too good to be true. But at least if it was, it was a power that a monster who was indebted to me had attained.

I checked my own level. 576. I was at 542 before slaying that witch. Since leveling took much more time the higher it was, the same amount of experience needed for Mae to get to 22 from 4 or 5 wouldn't even be halfway from 576 to 7. But still... gaining levels without risking your life in combat, or having to slay monsters. This witch had made perhaps one of the greatest breakthroughs in the history of potion crafting. I cursed myself for killing her, laying her to rest with the secrets she uncovered.

Hundreds of questions raced through my mind.

Could you gain more experience from higher level sexual partners? Did it have to be some sort of intercourse? What part of the process gave you more levels, the pleasure, the act, the orgasm itself? There were too many questions. I looked back down at Mae. she was about 2 feet taller now, her stat increases benefitting greatly from the low level she had started with. Not only could I experiment to try to answer my questions, but I could an indebted monster become more powerful. I tried not to think about the third reason I wanted to go again, but I couldn't get that sensation out of my mind. I wanted to experience it again. Badly.

"Yes, Mae, let's try it again, see if we can help you level up once more." I finally answered, my cock already leaking more precum as if it too could hear my approval. I laid back down, her new size causing her goo to spill out onto my belly, drooping down to cover my balls as well. I grabbed her on both sides with my bare hands. "Ready?"

"Ready!" She replied, and I immediately began to thrust my hips up off the ground. My high level gave me overwhelming speed and strength, but I took it slow in order to observe... and to try to enjoy it longer.

The sensation was just as good as before, no, even better, I realized. Perhaps it was because she was a higher level now, it increased her ability. "Oh, my god, Mae... you feel so good... I could do this forever-" I groaned, squeezing my eyes shut as I tried to hold back my orgasm from the onslaught of bliss assaulting my cock and balls, as if she knew at every moment exactly how much pressure to apply to each individual nerve ending. I couldn't help myself. I pumped faster, harder, ramming my cock all the way up inside of her as her body jiggled, attempting to stay centered around my dick as I fucked and fucked and fucked.

In almost no time at all, I felt my orgasm welling up again, as if I hadn't just cum a few minutes before. I couldn't hold it back, even as I tried, attempting to hold onto that wonderful edge for as long as I could, drowning in the ecstasy of it. But she was too skilled. It was like she was her slimey form were pressing up against my sack, coaxing out the cum churning inside, begging it to shoot out for her. And they didn't say no. I was barely able to enjoy it before I burst again, moaning on the floor, drool pooling in the corner of my mouth as I came again, shooting just as much, if not more than before.

I felt weak, exhausted, my mind hazy as I tried to recover. I couldn't even sit up, it was like a whole other person was laying on top of- I finally opened my eyes to find that Mae had tripled in size. She was heavy now, big enough to be considered a medium level slime. "What.. what the fuck.. when did that-"

I groaned, realizing I had been too caught up in it to track when she had leveled up. "Fuck... I guess we have to go again.." I tried to feel embarrassed or sad about it, but my cock was still raging hard, even if my body was growing tired. Even my movements felt slower.

"mmmmmm... yes, please, let's! I'm enjoying this so much, Will-" Her voice was smoother, almost angelic, as liquid as her body was. "Perhaps you would enjoy it more if I looked like, this-?" I watched as she transformed, her gelatinous body taking the shape of a human woman. She had gained enough levels that she could not only change her shape now, but was large enough to at least mimic the size, even if it was a bit on the smaller side. She had cut corners where she could, her ankles ending at little blobs instead of feet, short hair that covered most of where she would have placed her facial features, and a small, petite frame. She stood up at just around less than five feet, her A-cup breasts glowing with the light of her life orb hidden away in the core of her chest.

"I-I uhhh.." She walked up to me, stumbling forward as she got used to it for the first time, her gooey hands falling against my chest as she held herself steady. I gulped, my cock practically answering for me as it dribbled precum, throbbing with a heart beat that was pounding inside my head. "Yes.. yes that sounds wonderful."
