Porcus Humilis and Nymphara Matrona

Harry sat hunched on his wretched camp bed in the cramped cupboard under the stairs. The dim glow of a single bulb cast long shadows across the peeling walls. The Lust Book of Slytherin rested on his lap, radiating a warm, almost carnal heat. The black leather cover seemed alive—the silver serpent subtly coiled and shifted beneath his fingers. A thick, musky scent rose from the pages, a blend of old parchment, dark magic, and something sweetly depraved, animalistic, that made Harry’s blood boil in his veins.

He opened the book. The letters writhed as if alive, forming words directly before his eyes. Page after page revealed forbidden knowledge, crafted for those who were tired of being victims.

The first spell—"Subjugatio Carnalis"—complete subjugation of the flesh. With a drop of his blood on the victim’s tongue, Harry could **** anyone to feel an irresistible, primal lust for him. Their body would tremble, their mind filled with images of submission, their will melting like wax.

The second—"Transformatio Servilis"—the ritual of transformation into an obedient ****. The victim would slowly change, both physically and mentally: muscles weakening, mind dulling, until only one need remained—to serve their master, begging for the slightest attention.

The third—"Libido Infinita"—perpetual amplification of sexual hunger. The victim would become an obsessed nymphomaniac or a lust-crazed stud, capable of thinking only of cock, pussy, or the **** need to cum again and again.

The fourth—"Degradatio Bestialis"—partial bestial degradation. Hands and feet could turn into hooves, the face into a snout, the mind into something primitive, pig-like. Perfect for humiliation.

The fifth—"Cuckoldus Eternus"—for the spectators. It **** the victim to experience agonizing arousal at the sight of their loved ones being fucked and broken, while being powerless to intervene. Their cock would stand rigid, their mind consumed only by thoughts of their own helplessness.

The sixth—"Corpus Inflatus"—the ritual of hyper-body expansion. The victim would swell into fat, jiggling folds, their ass and belly growing enormous, heavy, and clumsy, their mind slow and dull.

The seventh—"Mentis Fractura"—mind breaking. A gradual erasure of personality, replacing pride with slavish devotion and animalistic lust.

The eighth—"Musk Dominantis"—permanent amplification of the master’s pheromones. Harry would emit a thick, heavy, alpha musk that would drive victims wild, making them drool and drop to their knees.

The ninth—"Breedslut Ritual"—transforming a woman into the perfect breeding slut-MILF: massive, swaying tits, wide hips, a constantly dripping pussy, and a mind wired only for one purpose—to breed and suck.

The tenth—"Porcus Humilis"—complete pig transformation. The victim would become an anthropomorphic, fat pig—stupid, lustful, with a huge belly, a dangling cock or a thick, gaping cunt, squealing with the desire to be used.

Harry flipped through the pages, reading more rituals and spells, his breathing growing heavier. His thin cock was already rock-hard in his pants, throbbing with anticipation. But two rituals caught his attention the most.

The first—"Porcus Domesticus"—complete transformation of Vernon and Dudley into anthropomorphic, stupid, fat pigs. Huge pink bellies, short thick legs, snouts instead of noses, tiny eyes, and constant drool. Their minds would be primitive, pig-like. They would remember who they once were but would be unable to resist their animal instincts: to eat, oink, and beg their new master for mercy.

The second—"Nymphara Matrona"—Petunia would transform into a hot, lustful nymphomaniac MILF. Her gaunt body would bloom: massive, heavy, milky tits that would sway and slap with every step, incredibly wide hips, a massive, soft, jiggling ass, a constantly wet, hungry pussy, and a mind wired for only one thing—to suck, fuck, and beg for a thick cock.

Harry closed the book. His heart pounded. ****. Real, dirty, animalistic ****.

Night fell over the Dursley house. Everyone was long asleep. Vernon snored like a boar, Dudley wheezed in his room, and Petunia lay stiffly on her bed.

Harry quietly stood up. In the cupboard, he cleared a small circle on the floor, lit candles from the pantry, and opened the book to the necessary pages. The air filled with a thick, sweetly musky aroma of dark magic.

First, he performed Porcus Domesticus on Vernon and Dudley. He drew runes with their blood and whispered ancient words. The magic surged in a heavy, viscous wave. Harry felt the power flowing into him—warm, potent, dominant.

Then came Nymphara Matrona for Petunia. Her hairs, taken from her hairbrush, were placed at the center of the ritual circle. The words spilled from his lips, thick and sweet, like cum.

The magic took effect instantly, but the changes would begin gradually—through the night, in their sleep, so that by morning, the Dursley house would be utterly transformed.

Harry sat in the darkness, breathing heavily, his cock hard as stone in his hand. The book lay beside him, pulsing in time with his heartbeat. The scent of lust and power filled the cupboard. He smiled in the dark—viciously, predatorily.
