My Stepmom is A Vampire

Chapter 1: Boring Night Shift  

The night shift was crowded, as always. Probably because the restaurant was just across from University X—ground zero for students desperate for coffee and survival.

It was a safe place for night owls and students who were basically the walking dead, cursed by the holy magic known as assignments.

The only way to survive? Never sleep and keep working. And pray the coffee doesn't run out.

That's what Seamus Danford thought as he watched another group of tired students walk into the restaurant, looking like zombies on their last leg.

He sighed and shook his head. He was a university student too, after all.

Pulling a notepad and pen from his pocket, he approached the table with a bright smile.

"What can I get for you tonight?"

"Black coffee, please… Can you make it seven shots?" 2

"Ugh, something sweet. I need a sugar rush, man."

"Lots, lots of sodas. Oh, and a chocolate cake would be nice."

Seamus kept smiling. It was a family restaurant, not exactly built for vague, chaotic orders—but judging by the vacant stares and dark under-eyes of the customers, they'd probably eat cardboard if it came with caffeine or frosting. 3

He just nodded and headed back to the kitchen.

"The hell is that?" the chef grunted when he heard the order. "We've only got pancakes."

"Pancakes covered with chocolate syrup should do."

"Right… Most of 'em are half-dead anyway. Won't know the difference."

The chef turned to get started while Seamus took a moment to breathe, dropping onto a spare stool in the kitchen. A woman in her mid-thirties approached him, cracking open a can of soda before handing it to him.

"You need this, boy."

"Thanks, Betty." Seamus took the can gratefully, popping the tab and taking a long drink. 2

"Feel like you're coming back to life, huh?" Betty smirked. "You know, you're too young to waste your life working graveyard shifts in a sad little diner."

"Go out, party, and meet some girls."

Seamus laughed. "Nah. I already have a girlfriend."

Betty shook her head dramatically. "What a shame. If I had a face like yours, I'd have an ego the size of Mount Everest."

"I'm not that handsome. You're just exaggerating." He rubbed the back of his neck, flustered.

Though, if he was honest, she wasn't entirely wrong.

He had short, jet-black hair, sharp green eyes, a strong jawline, and a pointed nose. The kind of face women liked, but too soft, too delicate for most men. He never fit in with those loud, macho guys full of testosterone. 5

"Maybe I'm exaggerating," Betty said, elbowing him playfully as she grabbed the food to deliver. "But hey, you're still a looker."

Seamus gave a small smile, but her words echoed in his mind. Maybe she was right.

He should be out there enjoying life, clubbing, making mistakes, living out the cliché of reckless youth. Instead, he was working two jobs just to pay off his father's debt and scrape through college.

Life was cruel like that. And even someone like him—someone who liked to think of himself as kind, decent, good—still got chewed up and spat out by the world.

His phone buzzed in his pocket, dragging him out of his thoughts. He pulled it out and scanned the messages.

[I need money. Lost again on those damned machines.]

[You think the owner's cheating me? I won yesterday!!] 1

[Also, I met a hot woman. Damn, son, want a new mom?] 2

[Anyway, money. Tomorrow.]

Seamus rolled his eyes. "Drunk again."

He loved his father. Really, he did. He was the only family he had left. But sometimes—God forgive him—he wished the man would just keel over in a dramatic accident or die doing something recklessly stupid.

It was a terrible thought. But maybe then, Seamus could finally breathe.

Maybe then, he'd be free.

***

When Seamus's shift ended, he ran through the usual end-of-day routine—balancing the cashier, tidying up the counters—while the cook began prepping for the next shift.

Suddenly, the hair on the back of his neck stood up. He jolted, looking around the empty restaurant. It was still dark outside, and he couldn't see anything clearly. But from the corner of his eye, something caught his attention.

Shining red.

"Eyes?" he murmured.

Lately, Seamus had the creeping feeling that someone had been following him everywhere he went, especially at night. Their aura was so distinct, it made him shiver.

He had tried to catch them before, but it never worked. Every time he noticed them, they vanished like smoke.

At this point, Seamus was sure it was a ghost. And honestly, that would be better. Ghosts couldn't hurt him like people could.

Then, something cold touched the back of his neck.

He gasped and spun around only to see Betty behind him, looking confused.

"What are you doing? Go home already!" she said, giving him a soft smack on the back.

"You scared me, Betty," he sighed.

Betty just laughed. The two of them finished up their tasks before heading out.

Luckily, Seamus's apartment wasn't far from the university. He could get a bit of rest before class.

When he got home, he slumped onto the worn couch—the only piece of furniture that felt like his.

The rundown apartment had just one, and his father often used it for… "fun" with whatever woman he brought home that night. No way in hell Seamus was sleeping in that bed. 2

The couch would do. It always did. 3

He drifted into sleep, only to jolt awake when the front door slammed open.

Seamus sat up quickly, heart racing, as a loud, slurred voice filled the apartment.

"Oh, my boy! Seamus! You're finally home!"

His father, Andrew, stumbled inside, completely wasted, again, and half-draped over a stranger.

Except this stranger wasn't just anyone.

A stunning woman walked in beside him. She looked completely out of place in this dump of an apartment. Tall and elegant, with a body like a model. Her black dress hugged every curve.

Her platinum-blonde hair flowed in perfect waves, and her red eyes gleamed in the darkness like jewels.

Seamus froze, just watching her as she practically carried his father inside.

'How the hell did that drunk old man manage to pull her?'

She met his gaze, eyes narrowing in amused tone. "Well? You just gonna sit there, or are you going to help me?"

Her voice was melodic and sweet. It made his skin crawl in a good way, which was concerning.

"Ah, uh... sorry, ma'am," he said, scrambling to his feet with awkward laughter.

He rushed over and helped carry Andrew, putting one of his dad's arms over his own shoulder.

Before they reached the bedroom, Andrew turned around with a goofy smile.

"Wait—wait! I haven't introduced you two yet!"

He gestured wildly between them. "This... is Isolde Velstrath! Your new stepmom!" 1

The woman—Isolde—sighed. "Dear, maybe save the introductions for when you're not slurring your words."

Seamus offered a weak smile. "Sorry about him."

"It's fine, Seamus," she said, and her lips curled into something resembling a smile.

But there was something off about it. It was as if she teasing him, lusting him. Like a hunter looking at her prey.

He blinked. 'Must be the bad lighting, yeah. That had to be it.'

Together, they dumped Andrew onto his bed.

"You can go now, boy!" his father called, half-conscious. "I wanna have fun with your future mom!"

Seamus rolled his eyes. "Lovely."

Chapter 2: Bloody Nightmare  

Seamus left the bedroom without a word and collapsed back onto the couch, sighing as he fished out his phone.

He needed a distraction—anything to scrub away the weird tension clinging to him after that strange encounter with Isolde.

He unlocked the screen to see new messages blinking from his girlfriend.

[Morning, honey!]

[What's your plan today? We've got the same class, right?! Let's eat lunch after?]

[Also, I have a surprise for you! No, no, it's not something "positive," you know~ But I promise you'll love it!] 1

Viviane.

He still wasn't sure how he'd pulled someone like her. They met during freshman orientation and just… clicked.

Their relationship was only a month old, but it already felt like they'd known each other for years.

His fingers moved quickly.

[Morning.]

[Yeah, let's eat lunch. I'm waiting for that surprise.]

He reread the message, gave a satisfied nod, and hit send.

Unfortunately, the moment of peace didn't last. A low creak echoed from the direction of his father's room.

Seamus plugged in his earphones and hit play. It was only 5 a.m. His class didn't start until 9. He could catch hours of sleep if he was lucky.

As the music poured into his ears, he closed his eyes and let himself drift. Until a piercing scream sliced through the sound.

He jolted upright, one earphone falling out. The scream had come from his father's room.

Groaning, Seamus rubbed his face. "Ugh... what the hell now?"

But the more he listened, the more his unease grew. That wasn't a moan or pleasure.

It was pain.

He stared at the door, unsure. "Okay... is Dad just into some seriously weird shit... or is something actually wrong?"

His pulse quickened and he swallowed.

"Alright, alright. I'll just... peek." 1

He stood up slowly, careful not to make a sound. The closer he got to the bedroom, the clearer it became, his father was screaming.

It wasn't just drunken yelling or some weird nightmare groaning; it was real, sharp, and filled with pain.

"Damn it..." he muttered as he rushed to the door and flung it open.

The sight that met him would burn itself into his memory forever.

There he saw Andrew, naked, lying on the bed with blood covering almost the entire mattress. His eyes were hollow, only the whites visible. His mouth hung open wide, locked in an expression of unimaginable pain.

And on top of him was that same woman, Isolde.

She was grinning, her mouth smeared with blood. Fangs peeked from behind her lips as she lazily licked the crimson from her fingers. 1

Her nearly naked body glistened under the dim light, red eyes glowing with hunger as she looked down at Andrew like she hadn't had her fill yet.

Then her eyes met his.

Seamus tried to control his breath. He had wished his father would die, sure—but not this dramatically. 2

He was too nervous to move, paralyzed on the spot, until he blinked and Isolde was suddenly in front of him.

Her cold hand with sharp nails touched his shoulder, freezing and unnatural. Her other hand grabbed his jaw as her face twisted with hunger, her eyes devouring him.

"My daughter is right," she whispered into his ear, her voice soft and chilling, "you are indeed tempting."

Seamus's eyes widened as if he'd just snapped out of a nightmare. His body finally moved, reacting purely out of instinct. He slapped her hand away and turned around to run, to scream, to do something.

Isolde didn't chase him. She only laughed, that same eerie, maniacal sound echoing like a curse as she screamed after him:

"YOU WILL NEVER RUN FROM US, SEAMUS! YOU ARE ALREADY OURS!"

Sweat poured from his temple like a fountain. He ran—desperately—tried to outrun whatever fear clung to his back. And just as he threw the front door open, he was greeted by her again.

Standing there, smiling.

"Boo."

Seamus jolted awake. Sweat flooded his body like no tomorrow. He was still on the same couch, in the same rundown apartment.

He touched his chest, arms, neck—nothing. No blood, no claws. Just his breath and his heartbeat.

The room was already bathed in sunlight and yellow lamp light. He let out a long sigh, then laughed awkwardly.

"Can't believe I had a dream like that... must've been that horror movie I watched with Vivi."

He shook his head.

"Boy! What are you doing? Come here! Your mother cooked something nice for us!"Andrew's voice called out from the small kitchen. 1

Seamus rolled his eyes. Of course his father was alive and well. 1

He approached the kitchen, just behind the couch, drawn by the smell of something delicious—bacon and eggs. A rare treat, he barely had time to eat properly with all his classes and double shifts.

He saw his father already eating with delight, grinning with a mouthful as he spoke.

"I've been trying to wake you up! You sleeping princess!"

Seamus only nodded and sat down across from him. But the moment he saw Isolde, his body tensed again.

She was cooking with her back turned, wearing the same black dress as before as if nothing happened.

And true, nothing happened, it was all just stupid nightmare.

But Seamus couldn't shake the image from the dream. The blood, her twisted smile. The way she said he was already theirs.

"What is it, Seamus? Did you have a nightmare?" Isolde asked as she placed a portion of eggs onto his plate. 1

Seamus shook his head vigorously. It was just a dream. A very bad dream.

"Ah, anyway, we're getting married tomorrow! Exciting, right? No need for a big celebration, just a simple wedding at the civil office. Neat!" 1

Andrew laughed, half-chewed egg still in his mouth, while Isolde, sitting beside him, smiled with that same suspicious curve of her lips.

Seamus didn't know what to say. It was too sudden. Too shady. But he knew his father wouldn't listen to reason, especially not when he was charmed and starry-eyed over a woman like her.

And Seamus couldn't even bring himself to look directly at them. Not with Isolde's gaze burning into him.

It wasn't the friendly glance of a future stepmother. It was the look of a predator.

Like she wanted to devour him.

'Was it really just a dream?' he thought.

But the doubt had already started to burn in his mind and it wasn't going away.

Chapter 3: Instant Wedding  

Seamus didn't even hear the lecturer during class, nor did he register a word when his girlfriend Viviane went on about her favorite TV shows in the cafeteria.

His mind was far too consumed by the nightmare, the one where his soon-to-be stepmother turned into a blood-drinking monster. Or was it a vampire? Either way, neither option was good. 2

"Seamus! Are you even listening to me?"

He finally snapped out of it when Viviane pinched his hand. He flinched and awkwardly answered, "Yes, yes! It's a good show, indeed."

Viviane sighed dramatically and let her head fall onto the table. "I can't believe my boyfriend doesn't give me attention... What a poor, beautiful girl I am."

Her long red hair sprawled across the table and even trailed onto the floor. Her golden eyes stared off into the distance like a heartbroken heroine in a tragic romance.

Seamus laughed softly. "I'm sorry. I just… had a really bad dream this morning."

Viviane turned her gaze toward him, though her head remained on the table. "A nightmare? Did all my horror recommendations finally mess with your head, honey?" she smirked.

"Shit, you're probably right…" he muttered, rubbing his temple. "I… I dreamt my stepmom killed my dad and drank his blood."

Viviane jolted upright, eyes wide. "Stepmom? You never told me about that!"

"Ah… yeah. My dad brought a woman home last night. Says he's getting married tomorrow."

"Oh wow. How is she? Is she beautiful?"

Seamus blinked. He knew too well this was a trap.

"You know how my dad is." He shrugged casually. "But you're still the most beautiful."

"There! That's a lie! I can hear it!" she huffed, crossing her arms.

"Come on, you don't actually think I'd be into my stepmom, do you? She gives off weird vibes."

"Isn't that every man's fantasy?" she said, one brow arched, deadpan. 6

"No! No way!" He shook his head vigorously, his whole body protesting.

Okay, maybe at first, he had noticed she was hot. But after that dream? Now just seeing her eyes made his spine crawl.

Thankfully, before Viviane could start grilling him with more dangerous questions, a voice came from behind him.

"Umm, Seamus? I found your notebook. I think you left it in class."

He turned to see Maria, his childhood friend. Short black hair, round glasses, and a smile as warm as always.

"Ah, Maria, thank you," he said as he accepted the notebook. "It's been a while since we talked."

She laughed lightly. "Yeah, you've been busy with someone." Her eyes flicked toward Viviane with a teasing grin.

"But we can still catch up over coffee sometime, if you're free." She waved and walked off, leaving the two of them behind.

When Seamus turned back around, Viviane's face was right in front of him. 1

Her golden eyes, usually full of mischief and warmth, now looked hollow.

"If you dare to cheat," she said, her voice cold and flat, "I'll kill your mistress, and we'll both die in the most horrible way imaginable." 3

Seamus froze.

Then she burst into laughter, flopping back in her seat. "Of course I'm joking! Did I scare you?" she giggled, sipping her drink like nothing had happened.

Seamus let out a slow breath. That was terrifying.

Sometimes, her words were extreme. But she only did it as a joke, or perhaps as a subtle warning to keep him away from other women.

Viviene was undeniably jealous, even if she never explicitly said so; her actions always spoke volumes.

They continued talking until the next class, Seamus completely forgetting about the surprise she told for him as tomorrow arrived faster than he anticipated.

***

"Sign this and this, and you will officially become husband and wife!"

The man in a button-up shirt beamed with an exaggerated smile, gesturing to the papers in front of him. 1

The bride and groom didn't look like newlyweds at all just a couple on a casual date. A simple white dress for the bride, and the same kind of shirt for the groom.

"Come here, Seamus! Give us the rings!" Andrew called out with a grin on his face. For the first time in a while, he wasn't drunk.

Seamus just sighed. He was the only one wearing a proper suit, holding a small pillow with two modest rings nestled in the box.

And wedding at night? That was unexpected even from his drunkard father. 1

He walked toward them slowly, the couple clapping like it was some cheesy party trick.

"You're the ring bearer now! Aren't you happy?"

Andrew said, taking one of the rings. Seamus rolled his eyes in response.

The groom placed the ring on the bride's finger, and the bride did the same. Just like that, they were newlyweds. But as Andrew leaned in to kiss Isolde, she raised a hand to cover his mouth.

"How about saving it for the wedding night?" 1

"Oh shoot! That'll be hot too! Now let's gooo!"

Seamus sighed again, following behind his "parents" toward the car, already wondering how many days this marriage would survive.

'If she lasts a month with Dad, it'll be a miracle,' he thought. 2

The car drove smoothly through the outskirts of Bord City, a small town known more for its gloomy scenery than anything else.

All year round it was either humid or cold. Most days the mist rolled down from the nearby mountain. Nights were icy, the sun barely breaking through the thick, suffocating clouds. 1

Forests taller than cathedrals surrounded the area as if they were in the middle of horror setting movie.

So no, Seamus wasn't surprised when he saw a massive mansion sitting atop a hill in the middle of a dark forest wrapped in fog.

It was just like any other depressing house in Bord.

"Are you nervous about your new home? And meeting your stepsisters, Seamus?" Isolde asked suddenly. 1

Her hand slid onto his thigh—tight—and moved a little too close to a very forbidden zone. He jolted in place. 2

"Ye-yes!" he blurted, his body turning cold. Then, after a pause, he added, "Uh… stepsisters?"

"Oh yeah, forgot to tell you," Andrew chimed in from the front seat, still grinning.

"My wife's got two beautiful daughters. I met the younger one, she's your age, and hot as hell!" 2

And there it was, his father's true colors, once again on full display. And Seamus hated it. 1

He sat stiffly in the back seat next to Isolde, while Andrew rode up front. It was awkward as hell, but no one seemed to care.

Isolde, for her part, answered casually, "Right? My sister lives in the same house too, but she and my eldest daughter are out of town. They'll be back in a week."

"Hear that, Seamus? This is gonna be fun!" Andrew laughed. 3

Seamus didn't answer. He sighed and leaned back in the seat, turning to look out the window. For a second, he felt sorry for Isolde.

But then he remembered how freaky she was and decided they probably deserved each other.

Chapter 4: My GF Is My Stepsister Now?

Seamus blinked as he stepped inside the manor. It wasn't as gloomy or dark as he'd imagined nothing like the vampire horror movies he used to watch with Viviane.

The grand foyer was vast and warmly lit, chandeliers glittering above as a small lineup of maids and butlers welcomed them with polite smiles.

Andrew was already all over it. He wandered around, gawking at the paintings, statues in every shape, and even the knight in full armor standing in the hallway like an old relic.

He looked like a tourist in a museum, not a man who had just gotten married.

He was clearly more excited about how rich his new "babe" was and all the gambling money he thought he'd now have.

"Damn! You must have an unlimited black card somewhere, right, babe?" Andrew laughed, his hand casually resting on Isolde's waist. She didn't respond, only nodded stiffly, her eyes still locked on Seamus with a glint that made his stomach twist.

Seamus tried to ignore it. His eyes were drawn instead to the grand staircase. Behind it was a stained-glass mural an angel with wings spread wide.

Then, a figure descended the stairs. Graceful, slow, and far too familiar.

Her red hair was styled beautifully today, her crimson dress hugged her body in all the worst ways, and her expression said it all: Surprise!

"What the hell is this?" Seamus turned to Isolde, voice low and sharp.

She only smiled that mocking kind of smile. The one that said checkmate.

"What do you mean, darling? That's my daughter. Viviane."

"Hello, Seamus. We meet again," Viviane said sweetly, already standing in front of him. She tilted her head slightly. "I told you I had a surprise, didn't I?"

His brows furrowed deeply. "We need to talk."

He grabbed her hand and led her to the nearest room without waiting for permission. No one followed.

It was dark inside, but the moonlight through the high windows offered just enough glow to see her clearly as she stood beside him.

"What is it, Seamus?" she asked innocently.

"Are you crazy?! Why didn't you tell me this sooner?" He let go of her hand and massaged his temple.

"Also, I didn't know your last name was Velstrath! I thought it was Haven!"

"Hm? I thought this would be a fun surprise." She shrugged. "And Haven is my middle name. Velstrath's my real surname, but I like abbreviating things."

Seamus looked at her in disbelief.

"But isn't it great?" she continued, stepping closer.

"Now we'll see each other every day… live in the same house… I can love you freely and be by your side forever." 3

Her words were sweet. They echoed with something wrong, something twisted beneath the softness.

Seamus sighed, his voice tight. "No, Vivi… it's not like that. What about what other people will think? We already get weird looks… now we're stepsiblings. My social life is going to implode." 1

Viviane placed her hands on her hips, her expression turning flat. "Like you had one to begin with." 5

Seamus blinked. That one hit harder than expected.

"Also, why should we care what others think?" she snapped. "They're just jealous."

"Well, I'm not the perfect golden princess, adored by all," Seamus muttered sarcastically, arms crossed.

Her eyes narrowed.

"So you're breaking up with me? Just because of this stupid coincidence, your dad marrying my mom?!" Her voice rose as she stomped her foot. "Even you, Seamus?! You too?!" 5

"No, that's not—" He faltered. The words wouldn't come. Because deep down, she wasn't wrong.

They were still the same couple. Just more... complicated.

Viviane stepped closer, gently cupping his face. Though she was about fifteen centimeters shorter, she tilted his chin down, her amber eyes boring into his.

"My whole life is just you," she whispered. "If you leave me, how can I go on living? How can I breathe, when you take everything away?" 6

Seamus stiffened. He recognized that line. It was straight out of that psycho horror film she made him watch. 2

But she wasn't done.

"And if you really want to leave me…" she murmured, her voice dropping into something colder and deeper, "then I'll have no choice but to decapitate your head… and keep it in a glass temple, so you'll still be in my life. Forever." 12

Her beautiful face didn't match her sadistic words. That made it worse. Way worse.

Seamus shivered. He didn't remember the dialogue being that psychopathic, but the message was clear.

"Alright, alright! I won't leave you, Vivi…" he muttered quickly. "Let's just… figure things out, together. Even if we're... step-siblings now." 6

Her smile bloomed instantly, bright and full of life.

She threw her arms around his neck. "Great! Should I start calling you step-bro now?"

"Nah. That's too much."

"You're no fun." She pouted, then leaned in. "Let this stepsister kiss you."

And before he could even react, she pressed her lips to his. It was gentle at first. He tried to pull away, but she was stronger than she looked.

The kiss started to turn hot, her gentle nibble turning into a bite until he was bleeding. It wasn't unusual, she loved doing that. And strangely, she always ended up sucking his blood. 9

Their tongues played and danced, saliva mixed with blood dripping to the floor. 2

He began to push her gently, guiding her back until she leaned against the window. Their breaths were ragged, but even then, it wasn't enough. They broke the kiss, both panting.

"Wanna go further, stepbrother?" she smirked, pressing her foot against his already hard length.

"Damn it, Vivi, stop calling me that." He wiped the mix of saliva and blood from his chin.

"What? Isn't it hotter this way? Don't you wanna screw your stepsister, brother?" she grinned, and he just rolled his eyes.

"Let's go to my room and keep the fun going," she said, dragging him out of the room while the two of them giggled into the night. 1

Chapter 5: BJ By Stepsister*  

Viviane opened his shirt, one button at a time, slow and teasing. Her lips trailing down his chest, kissing, licking, nibbling at the dips between his abs.

He flinched when her teeth scraped him. She almost bit, just enough to make him twitch.

Seamus grabbed her waist, fingers digging into her skin. "Calm down, Viviane. I'm not going anywhere."

She smirked, all hunger and fire. "Mmh… I love it when you say my name like that. Viviane." She whispered it like a prayer.

"It sounds so crisp, so fucking hot in your voice, like you're commanding me."

She giggled, hand sliding down his chest, brushing just above his groin. A faint trail of hair led her down, and she stopped right at the edge.

"I wonder if your junior agrees with me."

She bit her lip, slowly stripping off her dress. Behind that simple dress was her beautiful curved body, no bra, no shame.

Her breasts were perky, nipples already hard like they were begging for his mouth. She looked him dead in the eye, full of lust.

"I'm not wearing anything tonight behind my dress. Not when it's my first time fucking my stepbrother."

Seamus's throat bobbed as he swallowed hard. Their thing had only been going for a month, but it was already twisted, emotionally fucked and physically addicting. 1

They'd lost count of how many times they'd had sex, but somehow, every time it got nastier and hotter. She always knew how to rile him up, how to make him need her.

It was fucked up. But god, they both liked it that way. 3

"Hah… nothing at all?" His eyes trailed down her body, then locked on her soaked pussy. "You really are a slut for your stepbrother, huh?"

"Say it louder," Viviane laughed, wild and shameless. "You know the answer." 1

Seamus moved fast, his hands grabbing those perfect tits, twisting her pink nipples until her back arched and she gasped.

"Mmh~ You're impatient too, aren't you, brother?" she grinned, rubbing the bulge in his pants.

He was already rock hard, twitching under her touch. "I am," he growled. "So let's fucking start."

Viviane dropped down, her hands tugging at his pants and underwear. The moment it was all gone, his cock sprang free, thick, veiny, dripping at the tip.

She stared like she hadn't just sucked him off yesterday. Like it was new, like she craved it again.

"Come on, Sister, show me your skill."

Viviane grinned, she licked along the shaft, slow and filthy, letting her spit coat it from top to base. He groaned, head falling back, the way she tasted him like he was dessert.

"Shit… you're wetting it nice, huh?"

Viviane didn't answer. She held his shaft with one hand, slowly stroking the base while her mouth worked the top.

Her tongue swirled over the tip again and again, flicking that sensitive spot right under the crown, watching his stomach clench with every hit.

Then she took more, deeper this time. She gagged around it, tears pricking her eyes, but she didn't stop. Her lips stretched around his thickness, her throat clenching, spit dripping messily down the shaft.

Her eyes rolled back, like she was fucking addicted to it.

"Holy shit..."

Seamus murmured, her muscle throat was pulsating on his shaft like a pussy. It was wet, warm, and fucking good. 1

"Fuck," Seamus muttered, hand gripping her hair tighter now, the other clenched into the sheets. "You really want me to cum already?"

Viviane looked up at him without stopping, eyes glassy with heat, drool slipping past her lips as she bobbed her head.

Her spit was everywhere, stringing from her mouth to his cock, coating him in slick, messy wetness that only made him twitch harder in her grip.

She pulled off for a moment, panting, her lips red and swollen, a thin trail of saliva connecting them.

"Oh, I want you to last," she said with a grin, her voice rough with arousal. "But I love it when you lose control. I love watching you fall apart for me." 2

Then she sank back down, faster this time.

She pushed until the head hit the back of her throat, gagged, pulled back with a wet gasp, and went down again like she was chasing a high.

Her eyes fluttered. Her throat tightened around him. She wasn't just sucking him off, she was devouring him.

Seamus groaned louder, hips jerking forward before he could stop himself.

"Shit. Viviane!"

Her hand now moved in rhythm with her mouth, jerking the slick base while her lips stretched around the top half.

Her nose pressed into the soft skin of his abdomen again and again, and every time he flinched, she smiled around him.

"Hngghh~" she moaned, her pussy was dripping in heat right now, she wanted that fat dick so bad.

Seamus looked down and saw his now step sister like a bitch on her knees, tits pressed against his legs, spit drooling down her chin and onto his thighs, his cock stuffed in her throat and it nearly made him lose it right there.

"God, you're such a fucking mess…" he muttered, breathless.

"Hmm~" Viviane moaned around him in response, the vibration sending a jolt through his whole body.

She pulled back again, letting his cock fall from her lips, shiny with spit. She grinned, wiping her mouth with the back of her hand, eyes locked on his twitching shaft.

"You close, brother?"

"Yeah," he growled. "You're gonna make me cum if you keep going like that."

"Good," she said, grabbing him tight. "I want it."

She didn't wait. She took him back in, even deeper now, swallowing him whole like she needed it. Her hands held his thighs down as he instinctively tried to buck.

Her throat kept clenching, milking him with every motion. She wanted all of it, every drop.

Seamus groaned louder now, hand tangled in her hair, breathing ragged. "Fuck… I'm gonna cum!"

She moaned again, sucking harder, faster. That filthy slurp echoed in the room, wet and lewd and shameless.

He couldn't hold it anymore.

With a strained grunt, his body jerked and tensed, his cock throbbing hard as he came in her mouth, thick spurts shooting down her throat. She didn't flinch.

She swallowed every bit of it, moaning as he pulsed on her tongue, her eyes rolling slightly as if the taste was addictive. When he was done, she licked the tip once more, slow and teasing, then pulled away with a breathless laugh.

"Mmh… still the best flavor in the world."

She leaned up and kissed his lips, dragging some of that taste onto his tongue, slow and deep. 2

"How is it, blowjob by your sister?"

Seamus laughed, "Great, the greatest in the world?"

Both of them laughed for a while, controlling their breath to continue their next activity. The main course of the night.

Chapter 6: Special Day For New Stepsiblings**  

Viviane straddled him right after swallowing him down, her body still flushed, her thighs sticky from her own juices.

She didn't wait nor did she need permission. Her eyes were wild, pupils blown wide with lust as she lined herself up over his still-hard cock, the tip twitching and wet from her mouth.

Seamus was still catching his breath when she rubbed his tip against her folds, coating him in how wet she already was.

"Viviane, fuck, you're really horny now, don't you?" he rasped. 1

Never she been this excited before and it makes his heart beat fast. That girl always has a way to surprise him.

She chuckled low, teasing his cockhead against her entrance. "Stt, don't call me by my name tonight, stepbrother. Call me sister, yeah?"

Seamus could only laugh and nod.

"And yeah, I'm really horny now, I was wet the second you said my name."

Then, without warning, she slammed down on him. Her pussy perfectly hugged his thick cock as she moaned in pleasure.

"Ngghhh~ My stepbrother's cock is amazing~"

Seamus choked out a hiss as her tight, hot cunt swallowed him whole. Her walls clamped around him, squeezing like velvet vice.

The sudden pressure made his hips jerk up, instinctively thrusting deeper, and she gasped, a sharp, needy sound that turned into a throaty laugh.

"Ohhh~ Fuck, you're still so hard," she hissed, rolling her hips slowly as she adjusted to his size. "I should milk you again. See how long you last." 1

She started moving, grinding in a slow, tight circle, her hands on his chest for balance. Every shift made her walls flutter around him, dragging him deeper.

Her pussy was soaked, making every movement slick and noisy. It was messy, wet, raw, and perfect.

Seamus gritted his teeth, his hands flying to her hips. "You're insane, sister," he groaned. "You just made me cum, and now you're riding me like you want another one?"

Viviane leaned forward, her tits brushing his face as she whispered, "I want three."

Then she started to ride him properly, bouncing on his cock, up and down, fast and hungry. Every thrust made her moan, made her thighs slap against his hips, her hands gripping his shoulders for leverage.

"AHHH~ BROTHERR~ YOUR COCK TWITCHING INSIDE MEEHHH~"

Viviane's moan started to be higher, as her movement became faster. His cock hitting her perfect spot, making her shudder in need.

"Damn, Sister... Your pussy... Is trying to kill me, huh?" Seamus groaned, half jokingly as his eyes started to unfocus becasue of the pleasure.

The way she moved, frantic and unhinged was almost too much. She wasn't trying to be pretty about it. She was trying to break him.

"OHH!!! NGGHHH~ I'M BROTHER! I WILL DESTROY YOUU!!!" She tilted her head.

Seamus watched her through half-lidded eyes, her tits bouncing with every thrust, her hair clinging to her sweaty skin. Her lips were parted, breath ragged, eyes locked on his like she wanted to swallow him whole.

"Ahhh, Viviane-"

She cut him off with a kiss, wet, deep, tongue curling into his mouth as she slammed down on him harder. He could feel how close she was, the way her pussy clenched tighter with every grind.

"Ngghh~ You feel that?" she gasped between kisses. "That's me about to cum on your cock."

He could only groan in response, hips bucking up into her like his body had taken over.

"AHHHH!!! OHHH!!! I'M CUMMINGGG!!!"

Viviane threw her head back and let out a broken moan. Her whole body tensed as she came, pussy spasming around him, soaking his cock even more. Her nails dug into his chest, leaving red marks as she rode through it, not slowing down.

"Fuck—fuck, Sister!" Seamus couldn't hold it. He felt himself rising again, that second climax building fast, violent.

She looked down, smirking through her panting. "Ahhh!! Ohhh!!! G-go ahead.... Cum in me, Brother. I'm not pulling out tonight, I want your cum filling my womb!!!"

That was it.

He groaned loudly, hips slamming up into her as he came again, thick and hot, spilling deep inside her. Viviane moaned, her body shaking on top of him, clenching around every drop like she was trying to keep it inside.

She collapsed forward, breathing hard, sweat sticking their bodies together. For a long second, neither of them spoke. Just ragged breath and pounding hearts.

Viviane leaned down, lips brushing against Seamus's ear, her voice dark and playful.

"I'm not done yet."

"Wow, really? You're all out tonight, huh, Stepsister?" Seamus smirked, looking up at her body on top of him.

His cock was still buried inside her, and his cum kept dripping from her soaked pussy.

"Mmm… Because today is a special day," she said, slowly sitting up.

Moonlight poured in from the window, bathing her pale, glistening body. Her golden eyes looked dim—like something long dead—but still gleamed with hunger as they locked on him. Her smile was wide, crooked, and eerie. 1

Something about her was… different tonight. He couldn't explain it. Her skin was colder now. Colder than before.

Then she whispered, her voice soft but final.

"I'll tell you my secret, brother… and after that, you'll be mine. Forever."

***

Andrew was beyond thrilled for his wedding night with the hottest woman he'd ever laid eyes on. Rich, sexy, and clearly into him? Hell yeah. 8

"Damn, can't believe I scored an unlimited bank account! Let's go to Vegas after this," he muttered to himself, eyeing the room's decorations.

His gaze stopped at a painting on the wall—an elegant nude woman with long blonde hair coiled around a serpent, smiling like she knew something he didn't.

It was Lilith by John Collier, not that someone like Andrew had any clue.

All he could think was: How much could I sell this thing for? Would Isolde's money run out if he just kept gambling?

Too bad he didn't realize he was already gambling with his life.

The bathroom door creaked open. Isolde stepped out in a sheer black dress, her curves visible through the fabric, every step slow and deliberate.

Andrew's eyes lit up. "Damn, you're mad hot, darling! Let's have a lot of funsies tonight!" 3

He reached for her, but before he could even touch her, Isolde placed a single finger against his temple.

He collapsed instantly.

Isolde stared down at him with cool disinterest. "Hm… It's a shame you don't share that delicious blood like your boy," she murmured, tilting her head like she was studying a dying insect.

"But it's alright. As long as you're around, Seamus will stay trapped with us." 4

She smirked.

"At least you're useful."

With that, she turned and walked out of the room, the hem of her dress whispering over the wooden floor.

"I wonder what those two are doing now…" 10

Chapter 7: You Are Mine, Forever And Ever**  

Seamus barely had time to recover from his second orgasm when Viviane started grinding on him again.

Her hips moved slow, deep, milking every inch of him like she needed him inside her forever. 2

"Nnnngghhh~ Brother, I can't get enough of your cock," she licked his ear, as her body kept moving at the same pace.

"Ahhh... Ahhnn... Do you like how my pussy hugs you?"

Seamus grabbed her waist, trying to hold back his groan. "Of course, I love everything you do." He licked her jaw and down to her big tits that covered his face.

He licked her sweat, her body smelled like strawberry and mint. It drove him crazy as he started to move his hips, their movements becoming more wild.

"Ohhh~ Haaahhh~ You're really impatient, Brother."

Viviane squeezed his dark hair tight as she felt his tongue playing with her hard nipple, biting it and pulling it out like a baby.

Viviane's pussy became even wetter as the sounds of their sex echoed all over the room, wild and crazy.

"You and your tongue... Hnngg~ Love it! OHHHH!!! AAHHHH!!!"

Her moans were different now—hungrier, almost manic. Her nails dragged down his chest, not playfully, but rough, like she was trying to mark him. Own him.

"MMNNNHHH~ I can feel it still throbbing inside me!!!" she whispered, breathless, eyes glazed over.

"You taste good down here, Brother, but I bet you taste even better... up here." Her tongue licked his neck as he giggled, feeling it trace a circle on the same spot.

However, Seamus could feel something change. The hairs on his neck stood up. His body started to become alert as he felt her nibble turn into something more dangerous, blood pouring from his neck.

The air, thick and humid with sex, suddenly turned ice-cold. A chill swept through the room like a silent scream. Seamus froze, his breath caught in his throat.

The window slammed open on its own.

And he could see with his own eyes how the pale moonlight turned crimson. It hung high, glowing deep red, like a bleeding wound in the sky.

"What the hell—" Seamus's voice cracked.

Viviane stopped moving for a second, her eyes flashing something feral. Her lips curled up into a dark, twisted smile.

"Seamus, honey," she said, her hand cupping his head.

Her golden eyes were shining in the dim crimson night. Her mouth opened, showing the sharp and long fangs that made him shudder.

It was the same as the one he saw in his nightmare. The difference was... this was real, and he was the victim.

"I'm a vampire. And after I suck your blood, you'll be mine forever. You don't mind, right?" She tilted her head. "After all, you promised to be with me forever, remember?"

"So this is my lovely request for you, let's mate for life and become my bloody slave." She grinned, ear to ear. 2

Seamus widened his eyes. He wanted to ask if she was joking this time, if this was just some hot, nasty kink she loved.

However, before he could speak—before he could even think—he felt the sharp pain. Her fangs sank deep into his neck.

Seamus screamed or tried to. The sound never made it out. His body locked up, every muscle tensing as fire spread from her bite.

Blood poured from the wound, thick and fast, sliding down his collarbone, soaking the sheets beneath him.

"Mmmmhhhh~"

Viviane sucked his blood deep and kept riding him. She didn't even slow down. Her hips kept moving—faster, wilder—as if his blood only made her wetter.

Because it was true. His blood was so delicious, she couldn't stop. His blood made her horny to the bone. Her pussy kept twitching and clamping down on his cock, she wanted more!

She didn't even stop when Seamus's body turned cold and his skin turned pale.

Her moans turned guttural, animalistic. She drank from him like she was starving.

Seamus's eyes rolled back.

He couldn't move or scream or even push her off. His body was paralyzed, stuck between the high of pleasure and the drop of pure terror.

"V-Viviane..." he managed to gasp.

She lifted her head, her mouth covered in his blood, dripping down her chin.

Her smile was soaked in crimson.

"I told you I wasn't done," she purred. "You taste divine, Seamus. I could drink you forever." 2

He stared at her, heart pounding, body trembling. He was still inside her—she was still fucking him—and he could feel himself slipping.

Dying?

Everything started to fade. The red moon outside blurred in his vision. Her face distorted. The world felt far.

However, he could hear something in his brain, even though his mind kept telling him he would die—because of a hot vampire riding him—and Viviane moaned as her pussy fluttered like crazy.

[SYSTEM BOOTING…] 4

[RARE BLOODLINE DETECTED: VAMPIRE @#$$&-!?] 2

[SYSTEM ACTIVATED]

[Welcome, Seamus Danford.] 1

The glowing screen flashed in front of his eyes like a floating hallucination.

But he didn't have the strength to read more.

His eyes fluttered closed, and the last thing he felt was Viviane's body trembling around him. Moaning, twitching, cumming again as his blood stained her lips.

***

Isolde walked down the dark hallway, humming softly to herself. Her long dress trailed behind her, rustling against the cold stone floor like silk over bone.

She paused when she heard a sound—low and slithering: a hiss. The soft scrape of scales dragging along the ground.

A massive python slid past her, its thick body moving slowly.

Isolde smiled faintly. "Oh, Madeline, taking a walk?"

The snake—Madeline—stopped, glanced at her, then kept slithering forward without a sound, as if Isolde wasn't even there.

Her smile faded.

"Whore," she muttered under her breath.

She resumed walking until a sharp moan sliced through the silence, and the sweet, metallic scent of fresh blood hit her nose like perfume.

Her eyes widened. The veins on her temple pulsed, rising beneath her porcelain skin. Her expression twisted into something ugly, furious.

She moved, so fast the air cracked behind her.

In a blink, she stood in front of Viviane's bedroom door. She didn't knock. She threw it open, hard enough for the handle to crack against the wall.

The scene was as she expected. Viviane straddled Seamus, her hips still rolling lazily, mouth latched onto his neck.

Blood dripped from her lips to his chest, his body limp beneath her. She was fucking him like a feral thing, still lost in her hunger.

When the door slammed open, Viviane turned her head slowly, her mouth smeared in crimson.

"Oh, Mother," she said sweetly. "You just got here?"

Chapter 8: Mother & Daughter  

Isolde wanted to rip that smug smile off Viviane's face for breaking the agreement they had made, but she chose not to.

After all, she was a Matriarch Of Valstrath, she needed to be always in control and wise, especially facing a young, naive, and unstable vampire like Viviane.

She moved like a gust of wind, suddenly standing in front of her daughter. She grabbed Viviane's long red hair and yanked her to the floor, her naked body hitting the cold surface with a thud.

"How rude," Viviane muttered, unfazed as she propped herself up. "At least wait for me to cum."

Her pussy was still dripping from her own juices mixed with cum and clearly wasn't done with any of this.

But Isolde didn't care, her voice was cold and sharp like a dagger. "We agreed not to spill his blood until later. Have you lost your common sense?" Her expression twisted in disgust.

Viviane scowled. She sat up on the edge of the bed, her fingers lazily tracing Seamus's chest as he lay unconscious.

"So what?" she muttered. "I found him first while you were busy being a rotting corpse in bed."

She shrugged. "I have every right to taste him first. I'm the one he loves, remember?"

"Love?" Isolde scoffed. "You're older than this town and you're still using that childish excuse? That's why you'll never evolve, Viviane."

She took a step closer, her gaze sharp. "While your sister is out hunting and training, you're here playing with a human's heart like a teenage girl."

"Seamus would be disappointed if he saw the real you."

Viviane's fingers clenched tightly, she stood up, her fangs bared in fury as she snarled, "As if Seamus would ever fall for an old hag like you!"

The slap that followed echoed like thunder.

It wasn't a slap with ordinary strength. Isolde's blow sent Viviane flying across the room, crashing into the dresser with a loud crack.

"Don't you dare bare your fangs at me," Isolde said, calm and cold, "unless you want to be thrown out of this house."

Hands behind her back, she walked slowly toward her daughter, whose eyes now glowed golden with murderous rage.

Isolde stopped just in front of her. "Or maybe you'd be happier in another covenant, if they'd even want an unevolved whelp like you," she said with a cruel smile.

"You're a disgrace to the Velstrath name, Viviane. If you want to stay here, act like a good little dog."

"Fuck you!" Viviane screamed.

But Isolde only scoffed and turned her attention to Seamus, lifting him in her arms as if he weighed nothing.

Viviane bolted to her feet. "Where are you taking him?! He's mine!"

She moved to lunge, but Isolde's voice stopped her cold.

"Shut your mouth," Isolde hissed, her crimson eyes glowing, "or I'll trap you in a labyrinth of dreams until your mind crumbles."

Viviane froze. Her body trembled, the bravado shattered, fear flickering across her face.

"All bark, no fangs," Isolde said, shaking her head in disgust. "Still the same useless child."

She glanced down at Seamus, her gaze softening into something almost… affectionate.

"I'll bring him to his room. This place reeks of blood, it's no place for a human boy."

She began walking out, then paused by the doorway.

"Oh, and Viviane? You're grounded. You won't see him again until the inauguration. So behave."

With that, she disappeared into the hallway, Seamus limp in her arms.

Viviane stood in silence for a moment, her chest rising and falling rapidly.

Then her face twisted into pure rage.

For a few seconds, the room was silent. The only sound was the old clock on the wall, as if mocking her.

Then her scream shattered the air. "FUCKING BITCH!"

She grabbed the nearest chair and hurled it into the wall. It exploded into splinters. The table was next, kicked so hard it flipped and crashed, taking down the lamp with it. 1

"MATRIACH MY ASS!!! YOU ARE JUST A USURPER! A SLAVE!"

She stomped across the room like a storm, smashing everything she could touch. Her claws tore through the expensive velvet curtains.

The ornate dresser shattered under her heel. Glass cracked and rained like glittering dust as she punched the mirror, over and over, until her knuckles were bloodied, dark, and poisonous.

But she didn't care.

Her body trembled violently, teeth clenched, chest heaving with ragged breaths.

"AND HOW DARE SHE! HOW DARE SHE TOUCH HIM!" She stared at the ruined bed where Seamus had just been.

Her voice shook with rage, twisted rage that couldn't be explained with words. "THAT ROTTEN CORPSE LAID HER FILTHY HANDS ON HIM!"

She dropped to her knees, still naked, her hands digging into the floor like claws.

"Seamus… my Seamus… I found you first," she whispered, now sobbing with laughter, her golden eyes wide and glassy.

"You were mine before all of them. You love me. You love me. You told me you love me."

Her head snapped up like a beast sniffing blood.

"You're not allowed to love anyone else, okay?" she said to no one, to him, to the image of Seamus her mind conjured behind those broken eyes.

"Not her. Not any of them. Especially not that old witch."

She crawled back toward the wall and slammed her head against it once, and more and more.

"Stupid… stupid… stupid whore…" she hissed through gritted teeth.

"Treating me like a child. Like I'm nothing. Like I'm some broken toy." She let out a sick giggle. "I'll show you broken."

She stood slowly, her long red hair a mess, her body smeared with dirt, blood, and sweat. Her expression was unhinged now. No longer the seductive stepsister, just a monster with a shattered crown.

"FINE. FINE! YOU WANT TO CONTROL ME? LOCK ME UP? KEEP HIM FROM ME?" she shouted at the door, even though no one was there.

"THEN I'LL BURN THIS WHOLE FUCKING FAMILY TO THE GROUND." 3

Her voice dropped to a whisper, low and calculating, "I'll kill them all. My perfect mother. That quiet freak aunt. Even that bitch sister of mine when she gets back."

She stepped forward, barefoot through shattered glass, her lips curling into a deranged smile.

"I'll become the matriarch. The true Velstrath queen."

She opened the broken window and looked out at the mist-covered forest that stretched beyond the manor.

"And then…"

Her smile widened as her eyes softened, sickly sweet, almost loving.

"I'll take Seamus back… and keep him forever."

Chapter 9: Do You Want Me To Be Your Stepmother Or Lover?   2

Seamus's eyes shot open as he jolted upright, breath ragged, his whole body drenched in sweat. It felt like he'd just run a marathon.

Worse, his vision spun with stars before he collapsed back down onto the bed, dizzy and weak all over.

"What... what's happening to me?" he muttered groggily, one hand gripping his forehead.

His eyes darted around the room, and he realized that this wasn't his room. The walls were lined with ornate Victorian decor, the fireplace still warm with embers, the air thick with the scent of aged wood and polish.

Paintings hung in golden frames, the bed was massive, and everything screamed wealth.

"Ugh… my head… my stomach..." he groaned, covering his face. "I feel like throwing up."

Then he noticed something even weirder. Floating in the air before him was a glowing screen.

Just hovering there, like it was the most normal thing in the world. A system window. Like the ones from those cheap light novels or games he used to read at the bookstore during his shift. 1

It read:

---

[Welcome, Seamus]

[You have activated the Scarlet Purgatory Lust System]

[Would you like to see your status?] 1

---

He stared at it, completely blank for a few seconds.

'What the actual hell? A system? Like in a video game?'

He didn't know what was happening, but Seamus had a bad feeling about this.

Well, the light novel he read at least proves to him that the system sometimes brings chaos and suffering to those who hold it.

However, it wasn't like he had a choice at all. It was already there and he couldn't just ignore it.

Maybe it was the other system that brought 'heaven on earth' like sex since there was a 'Lust' in that name.

"…Screw it. Let's see it."

There were terms he didn't understand, but one thing stood out.

Race: Vampire ???

"…What?"

Suddenly his chest tightened. His heart slammed painfully against his ribs, and then it all came rushing back. Flashes of red, the memory like a blade scraping across his mind.

Viviane.

Her voice in his ear. Her fangs on his neck. The way she claimed him, called him hers.

"Forever and ever…"

The memory was too clear now. Too vivid to be a dream.

"No… that was just a nightmare… right?" he whispered.

---

[Incorrect.]

[That was a memory, Seamus Danford.]

[You are now a ??? type of vampire.]

[As your system that will guide you through evolution, I recommend you keep this information hidden for now.] 1

---

His throat tightened.

"No… no, no, that doesn't make sense. I'm just… I'm just some part-timer with a girlfriend! Why me? Why a system? Why vampires? And what do you mean by 'evolution'?!"

The questions kept pouring out, his breath speeding up again, as the world he knew began to crumble.

He gripped the blanket tightly, heart still racing.

Everything—his job, his school, his relationship, even his own body—had changed. And all of it, all this madness, started the moment he met his hot GF.

"…Dad…" he whispered.

If Viviane was a vampire, and now he was becoming one, then Andrew was either in danger… or already dead.

"Think about it… He met Isolde in a single night and then they got married. There's no way someone like her would want him in the first place."

"It was all planned," a woman's voice suddenly said.

Seamus jolted, eyes darting around until he saw Isolde already seated on the sofa in front of the fireplace.

He swore that she wasnt there a moment ago or inside the room. He didnt even hear someone enter the room!

Isole's crimson eyes glinting with interest.

"You're smarter than I thought," she smiled, "and not once have you acted like the world was ending. Good boy. I'm glad you'll be my son."

She stood and approached the bed.

Seamus instinctively scooted back, only to find the headboard pressing against his spine. Nowhere left to go.

Isolde reached out, lifting his chin with one perfectly manicured black nail. "Or… would you prefer me as your lover instead?"

He furrowed his brows. Under normal circumstances, he might not have refused such an offer. But this woman was a vampire: a blood-sucking monster who nearly drained him dry. 2

"Where is my father? What did you do to him?" 3

Isolde's smile briefly twisted into a frown, but her voice stayed calm. "Oh, he's fine. He's been enjoying himself, gambling again, of course. It seems he's living the best night of his life."

"You… didn't do anything to him? Like turn him into a vampire?"

Seamus touched the side of his neck instinctively. A small sting. When he pressed down, he felt it, a bite mark.

Noticing his reaction, Isolde's eye twitched. She reached for his hand, gently brushing the wound.

"I apologize for my daughter's… impatience. It wasn't supposed to happen like that. You must be terrified."

He blinked, surprised by her sudden sympathy.

But then she leaned closer, whispering in his ear, "We should've shared you, you know. My lovely boy."

Her hand moved slowly down his thigh, inching toward forbidden territory. 2

Seamus shivered. Her words were too cruel, her touch too calculated.

"And maybe," she added, her hand brushing against his erection, "you would've loved it."

He pushed her away. "You're all insane."

Clenching his fists, he demanded, "Why me? Why turn me? Is it because I'm close to Viviane?"

"Oh no, not at all, dear," Isolde said with a chuckle. "Your blood is special. Irresistible. Like nectar to us. We couldn't stop ourselves from tasting it."

"And you're not a vampire. We didn't 'turn' you. That would break the old rules. So don't worry, I'll take care of you. Physically… emotionally. Just think of me as your mother." 1

"Don't you miss her?"

"Don't you dare bring up my mom."

Isolde laughed softly. "Why are you so rude to me, dear? Don't you want to be loved by your mother? Or... the kind of love you shared with Viviane? Ah, that lucky girl…"

Her lips hovered over his neck, tongue flicking across the fading bite. She licked, slowly, savoring what little blood remained.

"Why don't you let your stepmother have just a little taste?"

Seamus tried to push her again but she was faster. She shoved him back onto the bed and climbed on top, straddling him with ease. In his weakened state, there was no way he could fight her off. 2

She pinned his wrist and brought it to her lips.

"Call me 'Mother,' my sweet child." 2

"That's—"

Before he could finish, her fangs sank into his wrist. He winced, blood spilling as she drank greedily. Crimson stained his shirt and dripped across the sheets.

"Ahhh... What a shame I have to share you with others," she murmured, licking her lips.

"It'd be so much more fun if it were just the two of us, forever. Don't you think, Seamus?"

Seamus didn't respond. His body burned. He was aroused, uncontrollably so. The moment she started drinking, he became hard.

"Oh? Are you getting excited?" Isolde purred. "Do you want your mommy to help you?"

Chapter 10: Call Me Mommy*   2

"Sh-shit! What are you doing to my body?" Seamus gasped, gritting his teeth.

His whole body was on fire, overwhelmed, pulsing, on the verge of breaking.

Isolde only laughed, slow and mocking, her fingers already trailing lower. Her touch wasn't kind, it was controlled and dangerously sexy.

"Oh, sweetheart," she cooed, her hand wrapping around his twitching shaft that was still covered, making him hiss.

"You didn't know? A vampire's bite is excruciatingly painful… that's why our saliva releases a powerful aphrodisiac. To dull the agony. To make you feel good instead."

She tugged his pants and underwear down in one graceful motion, letting his cock spring free: red, thick, twitching with need. The veins stood out, throbbing under her touch.

"My, my… what an eager young man," she purred.

Her fingers circled the swollen head, thumb pressing down over the sensitive slit. Seamus jerked, clutching at the white sheets beneath him.

"St-stop…" he panted, his voice weak and conflicted.

His heart didn't want to betray Viviane.

Even if she had betrayed him first by not telling him what she truly was, trapped him in this sick household, and turned him into a vampire or not based on Isolde. 2

Isolde's smile turned to a pout of mock disappointment. "Why?" she asked, tilting her head.

"Afraid of cheating on dear little Viviane?"

His eyes widened. Did she just read his mind?

Her lips curved into something wicked. "Oh, don't worry, my darling. Viviane knows… and she agrees to share you."

"Wh-what?" he stammered.

"Yes. It seems her kind of love is a little different, hmm?" She leaned closer, eyes gleaming. "But don't worry. As a good mother, I'll help soothe your heartbreak." 1

Before he could react, her grip tightened around his cock, veins throbbing against her palm. His body tensed, helpless, too far gone.

The aphrodisiac in his blood was stronger than his will now. His mind fogged. His hips twitched under her touch.

He closed his eyes. He didn't want to think about Viviane. Or the transformation. Or his father.

Not now.

Right now, the only thing that existed was his silver-haired stepmother stroking his aching cock with a face full of wicked amusement.

And it made him even harder.

"You really are easy to influence, aren't you?" she whispered. "But that's okay, sweetheart. Mommy's going to help you become a real man."

She shifted, lying between his legs. Her face hovered in front of his throbbing cock, tongue darting out to lick along the underside—slowly, from base to tip—making his shaft glisten with spit.

Seamus groaned, breath ragged. "F-fuck…"

"You like it, boy?" she murmured, her voice sultry, laced with hunger.

He nodded, dazed, hand trembling as he pushed his fingers through her soft silver hair. Then she moved to his balls, licking them clean, worshipping them with her tongue.

He nearly lost it.

"Hahhh… damn…" he muttered, struggling to keep himself grounded as she sucked his balls into her mouth, rolling them on her tongue like candy. 1

Seamus thought that Viviane was the kinkiest woman he had ever met, but it seemed like her mother was far more deprived than her. 1

She didn't let up. Her hand kept stroking his shaft in long, wet pumps, her saliva coating him with ease. His cock twitched harder, thicker—ready to explode.

Then she pulled away just a little, her voice low and sweet like poisoned honey.

"If you're a good boy and call me Mother, I'll let you cum. How about it?"

Her strokes slowed and teasing, keeping him right at the edge. He gritted his teeth.

Damn her. That wasn't a hard request. In fact, it was hot. But deep down, he knew…

If he said that word now, there was no going back. He'd fall, completely and utterly, into this twisted, depraved abyss.

"Come on, darling," she whispered, her fingers dancing around the slick head of his cock, smearing spit and precum together.

"It won't be that hard, will it? Just call me Mommy, like a good boy should…"

He gulped, his entire body trembling as his orgasm loomed and became unstoppable. While her hand kept moving slowly, driving him insane.

Seamus couldn't hold on any longer.

His whole body trembled, hips twitching beneath her strokes. His mind was drowning in heat, lust, and the drugged haze of vampire venom. The line between pleasure and madness blurred.

Her voice was soft, coaxing. "Say it, son. Say you want to cum with your mommy's hand."

He bit his lip, but the words slipped out like a dam breaking.

"Mother, make me cum..." 6

Isolde's eyes lit up with wicked satisfaction.

"Mmm, that's my good boy."

Without missing a beat, she lowered her mouth onto his cock, tongue flicking over the tip as she took him into her warm, wet mouth.

Her lips wrapped around him tightly, moving with a smooth, hungry rhythm. While her eyes keep observing his reaction with mischief in them.

"Ah—fuck!" Seamus gasped, his hips jerking as her mouth welcomed every inch.

She moaned around him, letting the vibration hum through his shaft. Her tongue danced against the underside as her head bobbed deeper and faster.

Her hand gripping his base to control the pace. Her other hand massaged his balls, keeping him steady as she devoured him like she had waited years to taste him.

Spit dripped down his cock, her throat slick and hot as she took him deep again, deeper than anyone ever had. His breath hitched, and sweat dripped from his body like a damp cloth.

He grabbed at her hair, moaning helplessly. "Shit, I'm gonna—"

She pulled back just long enough to whisper, "Cum for me, baby. Let your stepmother taste everything."

Then she sank back down with a wet, lewd sound. Tongue swirling, hand stroking, lips sucking like she owned him.

And Seamus broke. His body seized up, cock twitching violently as he spilled into her mouth.

He moaned loudly, breathless, hips bucking into her as she swallowed every drop without flinching.

Isolde moaned softly, savoring him, her tongue cleaning his tip before she finally pulled away with a wet pop. She licked her lips and smiled up at him.

"You taste divine, darling," she purred. "No wonder Viviane wanted to keep you all to herself." 1

Seamus lay there panting, his heart racing, body buzzing from both orgasm and venom. 1

And deep in his gut, he knew, there was no going back now. He was trapped here with hot lusty vampires that not only suck his blood but also his cock dry. 7

Chapter 11: Easy To Sway, Seamus  

Isolde didn't stop there, her hands brushed against Seamus's chest, slowly working at his buttons.

But then, she suddenly froze.

Her ears twitched, her expression turning slightly annoyed, like someone had just interrupted her favorite drama.

Still, when she turned to look at him, she smiled.

"What a shame... but we can't continue. I have a small cockroach to exterminate," she said sweetly, before slowly rising from his body and standing.

"Next time, let's continue our little mother-and-son bonding activity."

With that, she left the room, heels clicking softly against the polished floor leaving Seamus breathless, sweat still clinging to his skin.

At least now he had a moment to breathe. A moment to think.

Though of course, the system wasn't going to let him enjoy that peace.

"What? What does that even mean?" Seamus muttered, still overwhelmed by the glowing interface.

"Sex?! Letting them drink my blood?!" Seamus blinked. "Do you have any idea how insane these women are?!"

They hadn't exactly tried to kill him yet. The blood-sucking had been painful, yeah, but also mixed with… well, hot sex. 5

Still, Seamus knew crazy women when he saw them. And even if he kept dodging red flags—like he had with Viviane—it always came back to bite him. Literally. 4
