Hello! This is another submission for Terinas' Stocking Stuffer 2023 event! Here is the journal on FA: https://www.furaffinity.net/journal/10728053/

The kobold's slave finds themselves becoming more and more attached to his master but how will they feel after taking another of the potions that is stealing away their humanity?

This series will contain: Stockholm Syndrome, Pheromones, Transformation, Gender Transformation, Oviposition, Lactation, and other kinks that might not be to everyone's tastes.


I woke the next day under the blankets of the kobold's, my Master's, bed. My Master liked to sleep later in the day than I usually did. Daylight was precious in the plains of the north, we couldn't afford to waste it relaxing and sleeping into the afternoon. Not unless we had just completed a successful raid.

The black-scaled kobold was curled around my body, hugging me loosely. He apparently liked the warmth I gave off, though he wasn't cold-blooded like a lizard, as many of my people had believed. I had some time to think about my confinement but the more I thought about it the more I didn't care about leaving my previous life.

I don't know if that potion I drank changed more than I had thought or if Master's cum was just that good but either way I had changed. Despite sucking on my Master's cock over and over yesterday I didn't really see my Master as a male. I saw him as a kobold. It seems like an odd point of distinction but it was the truth. I looked over his shiny black scales, his clawed hands, his plump butt and thick tail, and I saw a kobold. One that was becoming more and more attractive to me by the moment.

Taking a deep breath, I took in my Master's scent. The spicy sweet cinnamon smell was starting to overwhelm even my own scent now. I suspected that it subsumed me more and more after every load of his cum I took into my mouth. The thought didn't bother me as much as it would have once. My masculinity was being overpowered by a small weak kobold and instead of being revolted, I reveled in it.

There was a stirring against my leg and I could taste the change of my Master's scent in the air. I didn't recall having such a strong sense of smell before drinking the potion but bathing in my Master's soothing scent made me grateful for the change rather than scared by Master's ability to alter me at such a base level.

Unable to hold back any longer I gently pulled his arm off of me. My Master has been asleep much too long and now, even in his sleep, his juicy cock was tempting me. I carefully pulled the blanket away from Master and delicately rolled him off of me so that I could look at his length again. On his back like this with his legs spread wide, I could see the two vents between his legs. His upper vent was where his mouth-watering cock was and below that, only a short stretch away, was his anal vent in a small cleft set into the kobold's tail.

I was happy Master's cock was separate from his ass but even the thought of licking under his tail disgusted me less than it once would have. I've quickly learned that all of Master's tastes and smells have become attractive to my newly altered senses. That didn't cloud my reason to the fact that Master's ass would still be filthy... at least without cleaning first. I felt my own traitorous cock stir at the thought. For now, I put that out of my mind and decided to take my prize.

Pulling the blanket back over the two of us I took Master's cock back into my mouth. I didn't want to wake him from the cold chill the lack of a blanket would cause and another traitorous part of me said I would enjoy being under the blanket where his scent couldn't escape. I sank down on Master's cock to the base where I could press my nose into the slight curve of his stomach and take in the spicy sweet smell of his crotch before I got started.

His taste was as amazing today as it was yesterday and I shivered in delight as his pre already began to leak into my mouth. I bobbed up and down on his cock excruciatingly slowly, trying my best not to wake him up and draw the blowjob out for as long as I could. I didn't think he would be upset to wake like this but I wanted to see how long I could get him to last before finally spilling his ambrosia over my tongue. Just the thought of the flavor made my hard cock throb against the blanket we were wrapped in.

It didn't take long for my self-control to crumble away and for me to speed up more than I thought I could get away with without waking him up. I couldn't stop myself though, as good as his small tastes of pre were, they only made me hungrier for the flavor of his cum. And so I sped up, fucking his cock in my own throat. I could feel him getting closer, his length spasming as he approached his peak.

Suddenly his hands tangled in my hair and he began to hump my face properly. I hadn't been successful in drawing a climax from him in his sleep but I didn't care about that anymore. I took in a deep breath of his aroused scent trapped under the blankets with me while his cock thrust in and out of my throat. In only a short time I had gotten more control over my tongue and throat, finding the best ways to pleasure my Master with it and bring me his cum faster. I clenched my throat around him just at the apex of his thrust and pushed him over the edge.

He pulled out enough to let me taste it, he had learned how to reward me as I had gotten better at pleasing him. Master seemed pleased by my submission to his cock in his sleep. I swallowed mouthful after mouthful of his cum and came myself despite never having touched my own cock throughout this experience. I savored every swallow, happy that my Master seemed so virile and potent with loads larger than I would have expected from such a small... creature.

Master threw off the blanket and looked down at me with my mouth still wrapped around his cock, still savoring his taste as his length returned back to its hiding place. Unfortunately, he did not allow me the pleasure of staying wrapped around it until his cock retreated all the way. He instead pushed me off and I rolled onto my back away from the smaller kobold.

He looked at the spot where I had cum with displeasure. "Human! Clean up mess, yes!"

I didn't like this order but I complied anyway. Master had pulled back the control of the collar so it wasn't as strict with me following all of his commands immediately. He had figured, correctly, that I would follow his commands anyway as long as I was addicted to his cum. And so I leaned forward and began lapping up my own.

It did not taste as good as Master's did but it also didn't taste as bad as I thought it would once. I had never tasted my own cum before coming here so I had nothing to compare it to but the flavor was inoffensive and frankly, less offensive than Master's cock had tasted before the potion. I didn't know what to do with that information. Have I become a cumslut for more than just Master, or did all kobold cum taste as good as Master's did? I wasn't sure if I would ever find out but for now, I would do anything Master said to get more.

Master didn't say much for the next few hours as he got started with work. He almost seemed to be grumbling about something but I wasn't sure if it was something I had done. At one point last night he told me that he was considering teaching me some of his alchemy, the art that allowed him to brew and enchant potions to do any number of bizarre effects such as the one I had drank yesterday.

For now, I followed him into his laboratory and watched as he cut up random herbs and grasses and mixed them with different colored liquids with the confidence that said he knew what he was doing. I had no way to help him, nor did I really have the desire to, so I just sat quietly and watched him work while I waited for him to want some more relief. Based on yesterday I didn't think I would have to wait long.

I had nearly fallen asleep by the time he finally came over to me with another potion in hand. This one was a dark forest green and smelled like pine needles. I hoped it didn't taste like it, I could tell that this was probably the next 'experiment' he intended me to drink.

"Human, come. We test potion in bedroom."

If this potion was anything like the last one then that hopefully meant I would get another tasty treat afterwards so I excitedly followed him to the bedroom.

"Good human, lay on back yes?"

I nodded and lay down in front of him. My cock was hard, not from the anticipation of the potion, but from what I expected to come afterward.

"What does this one do?" I asked.

Master nodded. "Will tell you, but first, drink!"

He handed me the potion and without any hesitation I drank it. The potion tasted like mint and the scent of pine but it wasn't so bad. It didn't taste as good as the first one but it also wasn't as bad as I had been worried about. Once I was finished with the potion I felt a warm feeling below my stomach and in my hips.

"Potion changes your body. Didn't like human making mess in the bed and thought this would make slave more valuable."

His words were like a bucket of cold water but before I could say anything an intense cramping hit me at the same time as my cock nearly exploded in pleasure. The mixture of pleasure and pain made me moan as I climaxed all over my stomach. The orgasm didn't slow at all once I climaxed, it just drew out longer and longer. I repeatedly cum and cum all over my chest until the spurting stopped but that didn't stop the orgasms from rolling over my body as it felt like my hips were being pulled apart. I reached down to my cock, only to feel it smaller in my hand. It continued to shrink even as the now minutes-long orgasm continued to rack my body.

Eventually, all of the pain of my changing form faded and all that was left was the continuous orgasm as my cock completely pulled into a slit between my legs. It wasn't until my cock was completely gone and I couldn't feel it anymore that the more than five-minute-long orgasm finally abated.

I was panting in exhaustion. I don't think I had ever wanted an orgasm to stop before but that intense feeling had been burning out my mind. When I finally caught my breath I reached between my legs and felt between them. The skin was completely featureless from the outside, the only thing that gave away that there was something there was the smooth featureless slit that traveled farther up my pubic bone than would be normal for a human woman.

The kobold pulled the new lips apart and I could smell my new altered scent. It didn't smell like a human, I didn't know what it was but I now smelled somewhere between my old scent and my Master's.

One of Master's claws slid between them and the effect was immediate. Pleasure made my toes curl as my hands pulled at the blankets of the bed. He pushed his fingers into a tight opening that stretched around them, the pull on the opening reigniting the intense pleasure of my previous orgasm.

"Slave no longer male, instead replaced with a female soralin genital vent. No pain receptors, only pleasure. Soralin vent always tight and stretches to size of mate, sometimes many times size. Farmers caught fucking stock but eggs tasty so everyone looks other way, heard rumors they feel good to fuck yes? We will test." The kobold rubbed my lower stomach. "If potion worked properly, slave will lay three eggs every morning, contribute toward household. Don't worry, soralin egg-laying very pleasurable, yes?"

I just stared blankly at the ceiling, unable to believe what I was hearing. I had known he was going to change me but... this is too much.

Before I could even begin to process what had happened to me, Master was climbing on the bed between my legs. "Master test fuck now yes? Master horny watching, don't worry, feel good yes!"

Before I could object he split my new vent apart and pressed his cock to the small opening hidden between the folds. My entire lower half lit up in pleasure the moment his cock touched me and I unconsciously moaned loudly to his touch. As if in response my entire vent leaked fluid and slicked up his cock. He rubbed his cock up and down the inside of my vent, not yet penetrating the new hole there. Even the small amount of friction made my entire body shudder in pleasure and when the tip of his cock finally met my entrance again my breath caught in my throat.

I didn't know if I wanted him to stop or keep going. I already felt like I was on the edge of orgasm and he hadn't even put it in yet. I didn't have to make up my mind about what I wanted because my Master decided for me.

With a rough thrust, the kobold entered my new passage and I immediately was brought to orgasm. My inner walls clenched and I could feel the entire length of his cock at once, every vein, curve, and divot that my insides pressed against. That got a moan out of Master too and he pulled out only to thrust back in just as hard. The second thrust nearly pushed me to another orgasm and all I could do was moan, shiver, and grip him inside me.

The pleasure was unimaginable and after only three thrusts I already have had two orgasms that rolled right into one another. They had me riding a wave that kept me high on pleasure, cresting and abating with every thrust of my Master's amazing cock. I shivered. I knew that this pleasure was going to keep me just as addicted to my Master's cock as his taste already did. The only difficult part would be deciding if I should beg him to fuck my throat or fuck my new lower half.

Any more thoughts left me once Master began to pick up speed with his thrusts. With an orgasm every two to three thrusts I wasn't able to keep my mind coherent so I instead rode the waves of orgasm as I felt Master's cock twitch and throb and get ever closer to his own peak.

Finally, with a final thrust, he shoved himself as deep as he could go and came inside of me. I had thought the constant orgasms through his fucking had been the peaks but I was wrong. Once I felt his cum begin to fill me it felt as if my entire body lit up with pleasure and my mind completely shut down. I no longer existed for that brief moment, all there was in the universe was mind-addling pleasure that made my eyes roll back. I probably moaned, I probably dug my fingers into the blankets, my toes probably curled, but I wasn't aware of any of that because I was nothing but a climax in that moment.

I didn't know how long I had been out when I came to but it couldn't have been long because my Master was still panting while curved over me, cock still hard and throbbing, though his orgasm had already stopped. I didn't even try to think about what happened I just laid there and squeezed my Master's cock through my new genitals while I took in the afterglow.

The first thought that came to me was one I was not proud of.

I wonder what the eggs will feel like.

Eventually, Master pulled out of me and sat to the side. I was still panting, not quite back to my normal breathing. With every pull of air, I could smell our mixed scents. After I came, my scent smelled just as sweet as Masters, and when they combined... I gasped as another smaller orgasm peaked through me just by focusing on our combined scents.

"Does pet want to clean Master?" The kobold asked.

My mouth started to water before I could answer. "Yes, Master! Please!"

He leaned against my face and pushed his beautiful cock into my mouth. I closed my eyes and savored the taste of our combined juices. My new enhanced senses could tell the tastes apart even as they mixed in my mouth. While I normally enjoyed his cum I could tell Master wasn't ready to reach his peak again and I was pretty tired myself so I just finished cleaning him and lightly suckled on his shaft until it retreated all the way back into its vent.

"T-take a shower when can walk again... pet."

"Yes, Master... Thank you for the potion."

Master trailed his small-scaled claw along my face. "Welcome... Good pet."

I passed out before he even finished leaving the room.
