-??:??pm Monday-

I had woken up in some kind of prison cell. It wasn’t any regular run-of-the-mill prison, the walls were covered in a rough, hard chitin, and my limbs were suspended above the ground by a green slimy substance, that seemed to harden the more I tried to wriggle out of it, yet retained enough tightness when not moving to restrain me.

I had no idea what time it was, there was no sunlight to indicate if it had turned morning, or if the darkness was a sign that it was still nearing the hours of midnight. There wasn’t any cracks in the wall to peek through, so I could only assume I was underground.

It was then that I had panicked, I was trapped Celestia knows how deep underground, in some dark, dirty and slimy cell, with no means of escape. It was only then I had tried to cast a teleportation spell, but only backfired and left me with a very painful headache.

I could hear buzzing. It wasn’t small, but rather getting louder, matched with very light hoofbeats. I could only assume whatever monsters that were guarding this place had sensed my attempts to escape, and were now on their way to finish me off.

I was rather surpised when I saw a humanoid figure walk into the cell, it was too dark to make anything but a silhoutte of a female figure. Suddenly a bright green light pierced the darkness, momentarily blinding me.

By the time my eyes had recovered the cell I was in had been illuminated with a soft green light, I could now see the figure in front of me in full detail. What had got me first was her sharp, green eyes, staring directly into my own, the crooked horn atop her head looked like it has been bitten, or had holes taken out of it, the same with her hooves. She was wearing a leather jacket (with what I assumed was nothing underneath) with a pair of insectoid wings jutting out from behind, and a pair of tight fitting jeans that hugged her form rather nicely.

I received a rather swift slap to the face from her right hand after she had noticed I was looking elsewhere. Leaving a rather large bruise on my muzzle, hidden beneath my fur.

Before I knew it, she had her back towards my front, rubbing her behind against my crotch, teasing my sheath with every pass. It was only then I had figured she was a changeling, the stuff of legends.
From what I remember, they fed on love, which is what she’s probably feasting on right now.

The moment I tried to speak out, she had clamped my muzzle shut with some unknown force, not unlike my own magic, yet it stinged a little. I tried to move my hips the other way, but she had already got a grasp on my stallionhood, giving it a firm squeeze with her mouth, her fangs just barely scraping against the rough skin.

It was then I got the message that I was to obey, or face a loss of my rather sensitive equipment. The rubbing went on for a few minutes, before she began visibly tiring of it.

She then began to unzip the leather jacket containing her precious round orbs, the vivid green nipples sticking out against her pitch black carapace, and manouvered them around my twitching cock, then followed her tongue, dancing along the sensitive flare, before englulfing just the tip with her mouth.

It felt heavenly, unlike anything I had felt before from the previous mares I had been with. She began to use this position to her advantage, bobbing up and down in a rapidly changing pace, the moment I would try to gyrate my hips in her direction, she would stop, making me suffer before she continued her ministrations.

I tried to warn her ahead of time before I succumbed to the pleasure I was receiving, but every time it was as if she knew by instinct, and started the whole cycle again. My cock was starting to feel sore at this point, sensing this, she had removed herself and her jeans, revealing a green entrance, with a greener still equivalent of a clitoris.

She forcibly brought my muzzle down to her level, the slime now accommodating my current, humiliating position, and released her grip.

I chose not to shout for help, but rather to help myself to what was presented to me. If I didn’t she would have made me do it anyway with her lust-inducing venom, without remorse. My tongue slowly made its way to its target, giving her behind a generous lick with my rough equine tongue, forcing a rather feminine moan out of my capturer.

I began to explore her insides with my tongue, it was not unlike a mare’s behind, but magnitudes softer and sensitive, resulting in my tongue getting trapped in the muscles lining her vaginal canal due to the sheer pressure the muscles were applying.

After my muzzle had been coated in her juices, she had decided that it was enough, and bent over in front of me. The restraints holding me in place went slack, which I could have used to escape, but for some bizarre reason all logic had left me in favor of thoughts of plowing this changeling’s behind.

I took my assigned place above her, and lined myself up with her entrance, thrusting forward and missing my target a few times, only pressing against her clit, forcing some rather throaty moans out of her, before finally slipping inside.

It was due to her wetness that my entire length was just entirely consumed, bumping against her cervix, yet it felt different somehow. With what I assume was a command in my lust driven stupor, I thrust forward with more enthusiasm than I care to admit.

Eventually she would start gyrating her hips in time with my thrusts, just barely poking through into the pouch of flesh that was her womb. With one well timed thrust, the tip broke though into the fleshy chamber, spurt after spurt of warm, sticky cum coated what I found out later to be her eggs, thoroughly fertilizing them.

After the job was done, she had left me wanting more, getting dressed and leaving the cell for what must have been days. Every so often I would be fed nutrients in the form of a green liquid, it wasn’t quite as sticky as the restraints, and had the consistency of water. Little did I know this would also serve as a means to drive my libido crazy, to the point where I would be thrusting into nothingness during the rest of my stay.

-??:??am Thursday-

The female changeling had returned to the cell, not bothering to wear anything this time. She explained that I had previously fertilized her eggs, and that I had served her well, it was unfortunate that I was to be the one to incubate them.

She made this clear when what appeared to be an ovipositor slowly slid out from underneath her clit, not entirely hardened. She shoved the entire thing deep into my throat, having a field day with my head, essentially skullfucking me.

When she felt she was close, she would withdraw, and turn me around on the spot with little to no effort, there was no backing out when she thrust the entire alien rod into my waiting hole, making a rather lewd wet sound as my balls slapped against my own cock.

The process went on for a while, before an orange sized egg traveled down its length and directly into my womb, I could feel it bounce after hitting the bottom of the soft lining, making its home at the very bottom of my womb. Several more smaller eggs followed, sending waves of pleasure down the changeling’s spine, illustrated by her twitching wings, these were to serve as the nutrients for the embryo to consume and become stronger.

She finally pulled out, but then got underneath me. Before I realized what she was up to, the hole in her ovipositor had been lined up with the flared head of my cock, I obediently thrusted inside, only needing a few more thrusts to bring her to a final climax, fluids began rushing out of the ovipositor and pushed out my cock, spewed a sweet smelling green liquid onto the floor below.

We both must have laid there for minutes, before she got up and released me. She told me I could leave, but that she would always be watching, and if anything ever happened to her child, she would end me and have my flesh fed to her many guards, stallionhood and all.

I hesitantly agreed, before struggling to get back on my feet. Several guards had been summoned to my cell and grabbed my midsection carefully, carried me out of the hive and deposited me just outside of Ponyville, my complete lack of energy was to blame for me blacking out the second time, the grass serving as a cushion for my slightly distended stomach.

Author's Note

Tenebra is in fact of both sexes, and this isn't his first rodeo.
He originally started out as a character made for roleplaying with friends, and has gone through a lot of renditions until I was finally happy with him, and this isn't my first piece of clopfic either, this is just the first to be uploaded here.

This also serves as kind of an alternate ending, seeing as he doesn't get brainwashed into being part of the hivemind.
