Chapter 1: Transforming encounter
"Come onnn~ I know you want this..."
I took a step back, my body feeling hot. I was just heading home from late night classes and decided to take a shortcut back to my place. But while I was walking through a dark alleyway, a horned figure stopped me in my tracks - an incubus.
He was tall and muscular, with short black hair and the accompanying devil tail and horns the demonkin had. I had never seen an actual demon before in my life, and certainly wasn't expecting one to show up after a mundane day of school.
"I can tell, love. You want to be fucked good and hard right here, don't you?"
"What? No!"
I immediately retorted, but despite always being straight, his vulgar movements and charm were playing in my mind. I turned away, walking to the other end of the alleyway at a brisk pace, his nude body lingering in my mind.
*poof*
"Well hey, that's not very polite~ You didn't even get a good look at tonight's dinner~"
In an instant he teleported in front of me, and lifted up his gargantuan penis before putting it in front of my eyes. I quickly turned away again, but it was too late. The smell, the girth, the length... every little detail of the massive demoncock was ingrained into my mind. My groin heated up more, feeling strangely conflicted - I was a straight male who hated the idea of another man's penis, but for some reason, my body needed the incubus' dick.
"There we go~ Hypnotized by the idea of being pounded into the floor by this meat stick? Being filled to the brim with demon jizz as its heat radiates through your body?"
I shuddered at the thought, before stumbling into one of the walls, panting heavily. This wasn't like me! What was happening...?
"You want to be a slut, don't you?"
Suddenly, the incubus snapped his fingers, and my clothes vanished, along with my books and other school necessities. He shoved me to the floor before slapping my ass hard, leaving a big red mark.
"OW! L-let me go!"
I tried to stand up, but my body was glued to the floor. Instead, I wriggled about, my ass shaking in the air, until the incubus grabbed my hips in his hand and dropped his hefty cock onto my back. I felt as drops of his precum dripped down my midback and down my shoulders. M-my midback?! Just how large was his dick?!
"Now, now. Don't struggle, this is your first step into your life as a WHORE!"
And with those words, he shoved his gargantuan dick into my ass, stretching my poor hole wide.
"OW OW OW OW OWWWW!!!!"
I winced in pain, as instantly my entrance was forced to accommodate the immense size of his member. It burned, it hurt... My insides stretched and contracted around the intruder, the sensation so foreign and intense that I couldn't help but let out a whimper. He continued to thrust, harder and deeper, causing me to arch my back and cry out.
"You fucking whore, you're enjoying this aren't you?!" the incubus growled, punctuating each word with a brutal, forceful thrust.
The burning, agonizing pain began to recede, replaced by a strange warmth that spread outwards from my ass, engulfing my entire body. The pleasure was overwhelming, intoxicating; I began moaning louder with each successive thrust. With each powerful pump, the incubus's thick cock drilled deeper inside me, filling me up completely. My mouth hung open, gasping for breath between guttural cries of pleasure.
"Fuck yes..." I murmured, barely registering what I was saying. It felt wrong, disgusting even – but it also felt incredible.
"How about I give this little BITCH an extra tasty treat?"
His spaded tail raised high in the air, before thrusting itself into my mouth.
"MMpH~!"
It began to wriggle about and thrust deep down my throat, making me gag and gasp for breath. But similarly with my backside, pleasure began to accumulate. My body was enjoying this, enjoying being taken from behind, enjoying having something thrust into my pipes, enjoying getting fucked from two sides, just like a good slut should...
"Alright SLUT. Get ready to be filled with an extra helping of hot demon cream!"
I snapped back to my senses, trying to move again, but my arms and legs were firmly stuck to the floor, and a whimpered in defeat as his cock and tail began to speed up in tempo, violating my poor holes with abandon. Then, without holding back, he came.
But it wasn't just from behind, no, simultaneously, his cock and his tail erupted in an explosion of white, hot cum being pumped into me from two sides at once. The salty and smelly batter shot down my throat, as my groin and stomach became slightly bloated from the sheer amount of semen being forcefully driven into my quivering body.
Eventually, he pulled out of my mouth, allowing me to finally speak.
"W-what the fuck man?! What do you-" and I covered my mouth, a cute yet sultry and seductive female voice coming out of it.
"HAHAHA!~ The changes have already started. I know you want to be a whimpering slutty fleshlight, so I'm only helping you fit the part~!"
As I sat confused on the floor, the demon cum inside of me was being absorbed by my body, and it was transforming as a result. My limbs began to weaken, slimming down and becoming feminine and dainty. I lost a good eight inches in height, leaving me a cute five foot one, perfect for carrying and then fucking the brains out of. My hair began to lengthen and turned a bright blonde, the silky locks tickling my shoulders. My face became cuter and more pouty, my eyes becoming a beautiful blue, and my lips plumping ever so slightly for kisses, but more importantly, cock-sucking. My shoulders cracked inward, my frame becoming more petite and girlish, before my chest and groin began to heat up. I intuitively knew what was coming, and I simply cried out as two mounds grew on my chest, and my penis began to shrivel away. As the breasts grew and grew, my dick shrunk and shrunk, until I had ample D breasts and a tiny less-than-an-inch limp dick left.
As the changes subsided, the incubus let out a sigh.
"I was hoping we could've finished in one, but it seems you still need a bit more work..."
He teleported again, and before I knew it, my small body was sat in his lap, my erogenous parts exposed to his deft hands. Before I could say a word, his arms held my body in place, as one hand pinched one of my sensitive nipples, and another shot down into my nethers.
"NO! L-let me go! LET ME GO!"
He pinched my nipple hard, pushing his head into the side of mine.
"Shut up, you WHORE. I know you're just a little bitch who wants to get reamed, so just sit tight and enjoy yourself," the incubus whispered into my ear, his tone a mix of smugness and arousal. His hand reached down to my crotch, squeezing my little cock affectionately. "You must be disappointed, having this worthless thing. You don't want to be a guy, you want something else...
I bet you can't wait to be bred by my demon seed, huh?"
My heart raced in my chest, my cheeks flushing red with embarrassment as his words hit their mark. Then with ease, he lifted my lithe body before slamming me down into his cock again.
"NGAH~!"
His cock was once again fully situated in me, my insides somehow accommodating its girth and length. I squealed in pleasure, as he began to buck his hips into me, while massaging my poor worthless dick and suckling a breast.
His hands and tongue worked magic, and I was fast approaching orgasm.
"Cum for me, you little slut," he cooed, his tone dripping with lust. "Show me how much you want to belong to me."
I writhed against him, unable to stop myself from responding to his demands. My poor little dick dribbled out the last of my cum, the amount not even enough to fill a teaspoon. The incubus ground his fingers into it, milking it until nothing else came out.
"You naughty little bitch," he chuckled, his voice low and husky. "Let me show you what cumming should really look like..."
With those words, he bucked his hips with greater ferocity, smashing his dick into my ass until a geyser of cum refilled my aching, wanting hole until it was dripping from my reddened cheeks. The hot sticky liquid once again seeped into my body, absorbed by my skin and innards.
Heat spread through my body, and my ass was the first to change this time. They bloated in size, my hips expanding to baby-birthing level, my ass bubbling into full, firm mounds, comfortably situated on the incubus' lap, devouring his cock in its new crevasse. My waist thinned into a beautiful hourglass shape, allowing the incubus the grip me even tighter than he already was. My blonde hair lengthened again, reaching down to my ass. The incubus fondled my breasts again in his hand, smiling as he watched them grow and grow into ridiculous size. He pinched my nipples hard, and I squealed in pleasure as milk began to pour from my puffy nubs.
"Mmmm... does mommy like her big milkers? Her sensitive slutty milk-sacs?"
He pinched them again before licking up some of the liquid on my swollen breasts. Then, he brought his hand down to my groin to massage my barely functioning cock, playing with it like it was playdough. But once it was "softened" enough, he thrust his fingers into my body.
"AAAHHNNGhh~! MYahh~!"
He pushed multiple thick fingers into my new hole, widening it, shaping it, deepening it, until it was producing copious amounts of fluid. A spray of clear girlcum coated his hand, and I moaned in ecstasy as my newborn pussy gripped his fingers tightly, grasping them with suction-y force.
"Ahhn~! AHHN~!" *moan*
I threw my head back in pleasure, as the final changes occurred. The little stubs on my head elongated into smooth pink horns, and my ears became pointed as well. My ass tingled pleasantly as a devil tail sprouted above it, becoming long and as sensitive as my breasts and pussy.
Finally, my transformation was complete.
Instead of the weak and gross college student there once was, a beautiful subby succubus slut remained, her comedically large breasts and ass causing her to orgasm from the slightest touch, her groin constantly wet and slick with fluid, her gorgeous hair and kissable face the perfect combination to seduce any man in the world.
She was the definition of a slut, a whore, the embodiment of the word lust.
And she was me.
I panted in pleasure as liquid pooled in my thick thighs, my body unconsciously grinding itself on the incubus behind me.
God, I need him in me...
I need him in me NOW!
