Hogwarts: The Rise of a Dark Heir [R-18]

Dawn broke.

Jerry, who hadn’t slept a wink, slowly concluded his meditation. He opened his eyes, stretching his slightly stiff limbs. He pulled a small vial of emerald-green Vitality Potion from his nightstand, uncorked it, and downed it. A gentle warmth surged through his throat, spreading across his body and washing away the exhaustion of the night’s mental strain.

Feeling his magic and physical strength replenish, Jerry hopped out of bed. After a quick wash, he changed into his school robes and headed to the Great Hall for breakfast.

At the Slytherin long table, Katherine was already seated, nibbling on a piece of toast. Seeing Jerry approach, she immediately waved him over.

"Good morning, Jerry."

"Morning," Jerry replied, pouring himself a glass of pumpkin juice.

Katherine then turned to the girl beside her. "Cassandra, this is the one I told you about—Jerry Rosier."

Jerry’s gaze followed the introduction, meeting his "mission target" for the first time.

Cassandra Warrington possessed an aura that stood in stark contrast to the lively students around her. She was taller than Katherine, wearing a perfectly tailored Slytherin robe, though the details set her apart. A black lace ribbon was tied around her collar, and her cuffs were adorned with matching lace. Her fingers were decorated with silver rings engraved with roses and serpents. Her makeup was subtle, accentuating her deep eye sockets and pale complexion. With her straight, jet-black hair, she looked like a gothic mistress stepped out of a medieval castle—cold, elegant, and hauntingly beautiful.

Cassandra looked up at Jerry. Her eyes were a misty grey-blue, beautiful but clouded with a faint, lingering sorrow that seemed etched into her very soul.

She nodded at him, her voice cool and melodious. "Hello, Jerry."

"Hello, senior," Jerry replied with a faint smile, his gaze unashamedly sweeping over her.

Cassandra met his scrutiny with a calm, practiced indifference. Jerry’s eyes drifted down to her unique robes. While Katherine prattled on about school gossip, Jerry focused entirely on Cassandra’s attire.

These weren’t standard-issue student robes. The fabric was high-grade, with a sheen far superior to the common uniform. However, Jerry’s sharp eyes caught the truth. In the bright light, the darker areas of the fabric showed signs of fading—whitish patches at the elbows and hem where friction was constant. Those "stylish" lace trimmings and silver embroideries were placed too perfectly, cleverly concealing areas that would otherwise show mending or wear.

Cassandra’s "individuality" wasn’t a choice of fashion; it was a desperate, meticulous attempt to disguise a set of old, worn-out robes. It was a mask of dignity maintained by a starving aristocrat.

Jerry’s lips twitched almost imperceptibly. Seeing the exhaustion in her grey-blue eyes, he understood. He suspected she was in a severe financial crisis, but he needed proof.

After Snape’s Defense Against the Dark Arts class, Jerry headed to the Great Hall for lunch. Instead of heading straight to his usual seat, he took a long detour past where Cassandra was sitting.

"Oh, damn it, my Galleon bag broke again," Jerry muttered with feigned annoyance. He tilted his velvet pouch intentionally.

Clatter!

Dozens of gleaming gold Galleons, along with a handful of silver Sickles and copper Knuts, poured out like a stream, scattering across the floor. The heavy ring of gold immediately drew the eyes of nearby students. In the relatively resource-poor environment of Hogwarts, this was a fortune.

"What a mess," Jerry grumbled, though he didn’t move to pick them up by hand. He casually waved his wand. "Accio."

The gold coins obediently flew back into his pouch. This display of careless wealth was calculated. He caught the fleeting, complex look of hunger and anxiety in Cassandra’s eyes before she looked away.

"Interesting," he thought.

As the clock struck noon, the sunlight was at its peak. This was the time when Hogwarts’ ghosts hid in the shadows, waiting for the sun to set.

In a deserted classroom, Katherine leaned against a dusty desk. Her fitted robes emphasized the near-perfect curves of her developing body. When the door opened and closed softly, she turned around.

"Did I keep my little kitten waiting?" Jerry asked, his voice clear in the quiet room.

Katherine broke into a seductive smile, pressing her soft body against him and wrapping her arms around his neck. "Never, my little lecherous master. Waiting for you is an honor," she whispered, her voice husky and teasing.

"Your tongue is sweet today," Jerry said, sliding a hand around her waist and pressing her tighter against him. She could feel the hard weight of his cock already awakening against her belly. "Did you find out what I asked for?"

"Of course." Katherine’s fingers traced the back of Jerry’s neck. She hung off him like a boneless cat. "Cassandra’s situation isn’t much of a secret among the upperclassmen. Her boyfriend, Orion Blackwood—the former Head Boy—is an ambitious half-blood."

She rested her cheek against Jerry’s chest. "That man is desperate to make a name for himself at the Ministry. But an Auror position requires money and connections he doesn’t have. He’s relying on grit and blood to earn merits. And our dear Cassandra is his primary financier."

"Financier?" Jerry repeated with interest.

"Yes," Katherine giggled, her laughter vibrating against Jerry’s chest. "Cassandra’s parents died in the conquest wars at the front. The Ministry gave her a massive compensation fund. Unfortunately, she’s spent almost all of it on that man—buying him equipment, bribing officials... I bet she has next to nothing left."

Jerry’s mental image of Cassandra solidified: a hollowed-out pure-blood orphan clinging to a lie to maintain her love and vanity.

As Jerry processed this, he felt Katherine’s arms loosen. Her hands began to slide down his chest with a deliberate, undeniable provocation. The room was empty. Her hand slid past his stomach and settled on the high bulge between his legs.

Katherine didn’t hesitate. Her palm cupped the massive organ through the thin fabric of his trousers. She could feel the enormous cock swell further in her grip, its pulse thumping against her hand.

She looked up, her eyes misty with lust. Her red lips brushed against Jerry’s ear as she let out a moan-like, sultry whisper: "Little master... look at how disobedient it is just because you’re thinking of another woman... should your kitten feed it for you now?"

Jerry’s eyes darkened. He looked down at her face, flushed with desire. He gripped her chin and tilted it up, his gaze filled with predatory aggression.

"You decide," Jerry said, his voice dropping to a command-like rasp.

Katherine’s eyes lit up. She stepped back and slowly knelt before him. Her skirt spread like petals on the floor, revealing her pale calves. Her movements were graceful, almost ritualistic.

She looked up at Jerry, her eyes burning with expectation. Jerry simply watched her, a meaningful curve on his lips.

Understanding, Katherine reached out with slender fingers to undo the belt of Jerry’s robes. She pulled the trousers down to his thighs, and the massive "meat rod"—which had been straining against the fabric—sprang out, twitching as it met the air.

Even for someone as experienced as Katherine, the sight of it made her heart tremble every time. It was as thick as her wrist. The glans was already weeping a small amount of pre-cum, glistening in the afternoon sun. The sheer size was enough to inspire fear.

Katherine didn’t retreat. Her lips parted slightly, her tongue darting out to moisten them. Then, holding her breath, she slowly and greedily took the massive head of his cock into her mouth.

Outside the classroom, Cassandra’s footsteps were nearly silent. She crouched low, creeping closer.

Ever since Katherine started flaunting her wealth, questions had plagued Cassandra. Those rare Arcane Resurgence potions weren’t something a student living on a scholarship could afford. She knew Katherine had either found a "Sugar Daddy" or gotten involved with a Dark Arts syndicate. Either way, for a desperate Cassandra, there was a profit to be made.

If it was a secret benefactor, she could blackmail Katherine for a "loan" to fund Orion’s needs. If it was Dark Magic, reporting a Dark Wizard to the Ministry would yield a bounty large enough to solve their problems and boost Orion’s career.

Cassandra pressed her ear to the door. She heard muffled groans and gasps. She held her breath, trying to distinguish the words. Suddenly, she heard a sound of extreme pleasure mixed with a sharp, wet slurping noise, followed by the sound of Katherine swallowing hard.

Cassandra’s mind went blank. She had never experienced it, but she had read enough whispered novels to know that sound. It was the sound of peak sexual desire.

She peeked through the gap in the door. Through the dim light, she saw a scene that froze her blood.

Katherine was on her knees, and Jerry Rosier... she could see Katherine’s mouth stuffed full by a massive, twitching object. Semen was already overflowing from the corners of her mouth, dripping to the floor.

The image exploded in Cassandra’s mind like a lightning strike. She clamped her hand over her mouth to keep from screaming. She didn’t stay to see more. She turned and fled down the corridor, disappearing into the shadows.

"Mmm..."

Jerry suddenly glanced toward the door, as if he had sensed something.

In that moment of distraction, he let out a low, repressed groan. His body tensed, and his fingers instinctively tightened in Katherine’s hair. Katherine’s mouth was filled to the brim by the enormous cock, making her breathing ragged. Her face was flushed deep red, but her eyes were excited. She worked her tongue around the head, the soft flesh of her throat rubbing against the sensitive ridges.

"Haa... ah..."

Jerry’s breathing became heavy. The small classroom was filled only with the wet sounds of suction and Jerry’s uncontrollable grunts.

Katherine’s throat emitted muffled whimpers as she felt the cock swell and burn in her mouth. Her tongue swept over the slit, sucking the pre-cum before dragging down the thick shaft.

Jerry’s eyes were squeezed shut, his muscles roping under his skin. He was on the verge of a total collapse.

"Ah... yes! It’s coming..."

Katherine felt the cock twitch violently in her mouth before a scorching torrent erupted.

Gulp... gulp...

The hot fluid, thick with masculine scent, surged into her mouth. There was so much of it—far more than she could hold. It overflowed from the corners of her lips, trailing down her chin and neck, soaking the collar of her robes.

Katherine coughed slightly from the sheer volume of the cum, but she didn’t let go. She swallowed desperately until Jerry’s tremors subsided and the massive rod began to slowly shrink in her mouth.

She looked up, her face, neck, and even the corners of her eyes smeared with milky-white fluid. She looked disheveled, but she possessed a radiant, satisfied beauty.

"Are you full, little master?" she rasped, her voice sultry despite the intensity of the act.

Jerry looked down at the kneeling, messy Katherine, feeling a surge of satisfaction and dominance. He reached out and gently brushed a stray lock of hair from her cheek, his fingers trailing through his own cum on her skin.

Jerry’s lust hadn’t fully vanished; his cock remained semi-hard. He didn’t pull away. Instead, he gripped the base and used the slick, wet head like a paintbrush on Katherine’s face.

He carefully and evenly spread the white fluid over her forehead, nose, cheeks, and chin, until her delicate face was covered in a thin "mask" of his unique scent. Throughout the process, Katherine remained as obedient as a kitten, even tilting her face up to meet his movements, a purring sound coming from her throat.

"Are there many upperclassmen like Cassandra?" Jerry asked casually, continuing the lewd act.

"Of course," Katherine replied, her voice still husky. She darted her tongue out to lick a stray streak of white from her lip, savoring the taste. "Little master, why do you think I risked Azkaban to rob Gringotts? Why do you think I spent my holidays clubbing lone Dark Wizards behind bars in Knockturn Alley?"

She leaned forward, her full breasts pressing against Jerry’s thigh. "It’s all because... I ran out of money."

Katherine licked more fluid from her fingers. "Hogwarts isn’t a fairy-tale castle, little master. For us upperclassmen—especially Slytherins—it’s a bottomless pit that burns through gold."

She explained the reality. The pressure of the O.W.L.s and N.E.W.T.s required expensive books and rare potions materials. The social cost in Slytherin was even higher; the quality of your robes, your quill, your vacation spots—all dictated your status. No one wanted to be isolated, so everyone faked wealth they didn’t have.

"And most importantly, the future," Katherine said realistically. "Want to enter the Ministry? Gringotts? A powerful Guild? You need gold to grease the wheels. Internships need ’donations,’ and apprenticeships with masters cost a fortune. Orion Blackwood isn’t an outlier; he’s the reality for every ambitious student from a modest background. By the sixth year, students will do anything for Galleons. Legal, illegal... they don’t care. Someone like Cassandra, who throws her parents’ money away for love, is actually... quite simple."

Just as Katherine was licking the base of Jerry’s thigh to show her submission, a set of rhythmic, steady footsteps echoed from the far end of the corridor.

Tap... tap... tap...

The sound bounced off the walls, sending a jolt through both of them. This wasn’t a student; it sounded like a professor or a prefect on patrol.

Katherine’s body froze. Her lust vanished, replaced by panic. She tried to stand, but Jerry pinned her shoulder.

"Don’t move," Jerry said calmly.

He scanned the room. There was only one exit. Running meant getting caught. As the footsteps reached the door, Jerry drew his wand and flicked it toward himself and Katherine. A silent Disillusionment Charm washed over them.

Their forms didn’t vanish completely but blurred and twisted, mimicking the color and texture of the wall behind them, blending perfectly into the shadows of the corner. 𝚏𝗿𝗲𝐞𝐰𝚎𝕓𝐧𝚘𝘃𝗲𝐥.𝐜𝚘𝕞

A second later, the door creaked open. The ghost of Professor Binns floated in. He drifted through the air, his transparent body shimmering in the sunlight. He scanned the room with hollow eyes, looking for students breaking the rules.

Katherine held her breath, her heart hammering against her ribs. She was still kneeling at Jerry’s feet, her face covered in cum, her body pressed against his leg. She felt the chill of the ghost as he floated past.

Finding nothing, Binns drifted back out. When the footsteps (or rather, the echo of them he left behind) faded, Jerry released the charm.

Katherine exhaled, collapsing into a heap on the floor. Those few seconds were more stressful than a bank heist.

Jerry adjusted his clothes, tucking his cooling cock back into his trousers. He looked at the messy, seductive girl on the floor. "Alright, get up, kitten. Go wash your face."

Katherine looked up with a smile that mixed lingering fear with excitement. "Yes, little master," she whispered. "Transfiguration starts soon. You should get to class."

She gave him one last look before scurrying out toward the girls’ lavatory. Jerry smoothed his robes, ensured there were no suspicious marks, and began his stroll toward the Transfiguration classroom.
