I stirred from my sleep, groggily rubbing my eyes as I scanned around my dark room. A weird presence had woken me up, although I didn’t necessarily feel threatened; but I knew someone else was in here with me. I suddenly felt a hand brush up against my inner thigh, startling me. Once my eyes adjusted to the darkness, I looked to my side, only to see someone… or something… sitting next to me on the bed. They were an anthropomorphic canine of some sort, though their species wasn’t discernable. Their large black body towered over me, as their massive hand easily fit all around my thigh. My cheeks burned as I began to feel my pants tighten around my crotch, despite the rather strange situation I found myself in.
“Uhm… who are you?” I asked awkwardly.
The being chuckled. “That’s not very important, but for your sake I’ll tell you. I am Marchosias, commander of the thirty legions, but like I said, that’s not why I’m here. What I want from you is a lot more simpler,” he said in a low, husky voice.
“Then what DO you want?”
Marchosias grinned. “I simply wish to fulfill one of my deepest and most carnal desires, and out of all the humans, you looked like quite the enticing one to corrupt.”
I looked at the being with a raised eyebrow, my thoughts melding together in confusion. “...huh?”
He huffed in amusement, grinning as he continued to caress my thigh. “I want to spread my seed within you, and corrupt your very soul until it is unsalvageable.”
My heart skipped a beat as I finally understood what he was getting at. A small part of me was saying that having sex with what was clearly a demon was probably the worst decision I could make; but on the other hand, I didn’t exactly wanna turn down the opportunity of a lifetime. Also, he was admittedly pretty hot.
“Sure, I accept; I want to be corrupted by you,” I said as sensually as possible, although it came out pretty awkward in reality.
Upon hearing my consent, Marchosias pounced on me, pinning me against my mattress with his giant arms. He wasted no time starting to get intimate with me, planting several kisses on my lips. He got more and more desperate the longer we kissed, biting my upper lip and trying to force my mouth open with his tongue. I eventually gave in, allowing him to access the inside of my mouth. The wolf began roughly making out with me, pushing his long tongue deep into my mouth and down my throat; almost to the point where I was sucking on it. Meanwhile, he began grinding his body against me, allowing me to feel his throbbing boner beneath his cloak. Warm spit flowed down my throat as Marchosias continued to make out with me, grunting and huffing as his boner leaked cups of precum all over both me and my bed.
Once he was satisfied, the demon pulled his tongue out of my mouth, going out of his way to slurp around my uvula and the roof of my mouth. I panted heavily as I finally got a chance to catch my breath after such an intense make-out session. Marchosias, however, was quite impatient, grabbing my waist with both hands and flinging me over his torso as he began to lay down on my bed. Using some sort of magic, he got rid of both my clothes as well as his, leaving us both naked on the bed. He then collected some of his precum, using it to lube up both his fingers and my butthole. The precum numbed and relaxed my hole, allowing him to effortlessly insert one of his large fingers deep into me. I moaned in pleasure as I felt him prodding around my insides, eventually finding my prostate and pressing down on it. My legs shook involuntarily as my prostate got flattened by Marchosias’ finger, making me leak precum as I buried my face into his voluptuous pecs.
“Yeahh, that’s it. Good boy,” he said as he thoroughly massaged my prostate, earning a cacophony of moans from me.
The demon eventually inserted two more thick fingers into me, spreading my hole so much more than I ever had. Once he felt like I was spread out enough, he took his fingers out of me, using his strength to switch our positions so that I was laying on my back. Now that I had a good view of Marchosias’ front, I was finally able to see his cock. It was… interesting, to say the least. It was at least two feet long, and appeared prehensile. The head ended in a large flare, with several soft, fleshy spines protruding from it. Large veins ran along its entire length, which expanded and pulsated each time it throbbed. At the base of his cock was a large, vascular knot which throbbed even harder than the member itself. Underneath all that were two large, low-hanging, virile testicles churning with an ungodly amount of seed. I breathed in deeply as I observed the wolf lining himself up, getting ready to penetrate me.
Marchosias stroked his cock in preparation, spreading a thick coating of precum along his entire length. Once he was ready, he began inserting the tip into my hole, doing so without much issue. I immediately broke out into a choir of moans as I felt him plunge his powerful cock deeper into me, my guts getting flooded with buckets of sticky precum. As he got deeper into me, I felt his cock snake its way around my insides, almost as if he was literally rearranging my guts; my torso and stomach bulging out as it did so. Every time it throbbed, I felt all those veins expand and pulsate, making the whole experience much more pleasurable. I eventually felt his large knot press against my hole, indicating that he was all the way inside me.
After giving me a few minutes to get used to his length, the demon began mercilessly fucking me. I let out loud, filthy moans as wave after wave of pure pleasure permeated throughout my entire body.
“You like that, pup?” Marchosias said with a grin, sticking his tongue out as he huffed.
“Haah… y-yes, I love it so much… mmh” I moaned.
The demon growled back. “Yeah? Tell me just how much you love it.”
“I- I… mmh… I love s-so much, daddy… a-ahh. P-please don’t stop… haah.”
“Good… good boy,” he replied.
The more I moaned, the faster and rougher Marchosias’ thrusts became. The powerful throbbing of his cock, combined with the way it was snaked all around my guts, made the experience infinitely more pleasurable. Because of the sheer overload of pleasure, I quickly felt very close to my limit; although it seemed like the demon wasn’t too far behind. He groaned and grunted louder and louder, bearing his teeth as he thrust more forcefully into me. With one final, powerful thrust, I felt his thick knot pop into me, completely flattening my prostate, My body seized and convulsed as I experienced the most powerful and intense orgasm I ever had. My vision turned black as all my brain could process was the sheer bliss I had entered in, my orgasm being exponentially amplified by Marchosias’ supernatural cock. Not long after my spasms began, the wolf himself also began to shake and tremble. Jets of boiling hot cum were pumped deep into me as he began unloading his giant testicles into me. My guts gurgled and groaned as they were filled to the brim with gallons upon gallons of scalding seed; my stomach bulging out in order to accommodate the immense volume of sperm.
My orgasm eventually began to fade, allowing me to regain some of my bearings as my brain was finally able to process things other than pure bliss. The first thing I noticed was that Marchosias was still grunting and groaning, his jaw clenched tight as bursts of cum continued shooting forth from his cock. His balls continued throbbing as the minutes went by, seemingly creating more sperm in real time for him to unload into me. I could even feel the sheer volume of sperm swimming around in my guts, wriggling all around inside me like worms. The demon’s cumshots eventually began to decrease in power, until only small dribbles came out from the tip of his cock. He exited my hole with a pop, my guts gurgling and glorping as the gallons of cum settled around inside me. A strange sigil then appeared on my stomach, seemingly confirming that I had been thoroughly “corrupted” by the demon.
Marchosias picked me up, switching our positions yet again so that I was laying on top of him. I buried my head between his pecs once again, the feeling of his soft fur and rhythmic heartbeat lulling me to sleep. He gently petted and caressed my head, planting a loving kiss on my forehead.
“I love you, my newly created vessel,” he whispered, before the both of us succumbed to our exhaustion.
