Deadly desires: the Donna's obsession.

The morning sunlight filtered through the wide glass windows of Valmont High, casting sharp beams on the polished floors.

Killian leaned back in his chair, his eyes fixed on the ceiling as yesterday's conversation replayed in his mind.

"But you're wrong, boy. You don't even know what you're dealing with. She's more than just dangerous. She's a fucking forest fire waiting to burn you alive."

Forest fire? What did that even mean?

Why the heck did that old man like speaking in riddles?

Though, now that he thought about it, something did seem off.

From his research, he had noticed that Scarlett Voss didn't usually waltz into someone's territory.

Especially if it was without reason.

She was here for something, or someone. And it wasn't hard to guess who that someone was.

Him.

The thought made his jaw tighten.

Did she really think he wouldn't notice?

Was she even trying to be subtle about it?

Or did she think he didn't know who she really was? That her identity was some well-kept secret?

He smirked bitterly.

He'd known her true identity from the moment she set foot in Las Vegas - Lilith Russo, the ruthless Donna of a powerful mafia empire masquerading as CEO.

He had been so glad the day he found out she was coming and that he would finally be able to get his revenge, that he had gone to a gala and ended up sleeping with a stranger.

Though that really wasn't a problem.

It wasn't like it was his first time.

But his father's warning had sparked a new question.

What did she really want?

Wait.

Suddenly, itt hit him like a slap.

"Don't tell me, she's here for it."

As if on cue, Scarlett suddenly appeared at the doorway.

Speak of the devil and she arrives.

She sure had a long life ahead of her.

Scarlett surveyed the class, like a queen surveying her kingdom.

She was dressed in a white suit, tailored to perfection, the sharp edges of her blazer emphasizing her deadly curves. A black silk blouse peeked out beneath, paired with black heels that were sharp enough to kill.

Her hair was pulled into a sleek bun, a single strand falling against her cheek.

Italian Mafia queen.

The thought struck Killian before he could stop it.

She walked into the room, her dark eyes locking onto him immediately.

Killian froze.

There it was again, that unspoken challenge, that magnetic pull that made it impossible to look away.

But he forced himself to.

His gaze shifted, landing on the ceiling, as if she were nothing more than a fly.

At that moment, a petite girl with pigtails stepped into his line of sight, blocking Scarlett from view.

She wore a short pleated skirt and a white uniform top was tight, clinging to her curves. Her bright pink lips curved into a playful smile.

"You look bored," she teased, tilting her head.

Killian smirked faintly, leaning forward. "You have no idea."

"Well, I can fix that," she grinned, biting her lip seductively.

Her boldness made him chuckle. "Yeah? How?"

Her eyes sparkled mischievously. "Come with me, and I'll show you."

Killian raised an eyebrow but didn't protest when she grabbed his hand and tugged him out of his seat, walking towards the door.

As they passed Scarlett, her gaze followed them like a hawk zeroing in on its prey.

Her brows furrowed, lips pressing into a thin line as she watched the girl drag him out of the room.

She took a step forward, her hand already reaching for the door when a sharp sting on her backside stopped her.

Paah!!

The sound of a slap echoed through the room.

Scarlett turned sharply, her dark eyes narrowing as she found Liam standing behind her, his hand still mid-air.

He was smirking, that same cocky grin from yesterday plastered across his face.

"So soft," he muttered, his voice low but loud enough for her to hear.

She blinked once, twice.

Did she just get spanked? By a kid?

The room seemed to tilt as a cold fury washed over her.

For a moment, she said nothing. Just stared at him, her eyes darker than a storm cloud.

"What?" Liam asked, feigning innocence. "Did I cross a line? Come on, I was just playing..."

His words trailed off because Scarlett suddenly smiled.

The kind of smile that made grown men wish they'd never been born.

"You like touching things that don't belong to you?" She asked, her voice calm, almost sweet.

Liam laughed nervously, taking a step back. "Relax, it's just a joke..."

Before he could finish, Scarlett's hand shot out, grabbing his wrist in a vice-like grip.

His smirk vanished instantly.

"What are you doing?" he demanded, trying to pull away.

Scarlett tilted her head, studying him like he was an insect she was deciding whether to squash.

Her grip tightened, and he winced. "Let go!"

"Oh, I will," she murmured. "Right after I teach you some manners."

"For what? It was just a..."

She moved faster than he could react, twisting his wrist at an unnatural angle.

"AHHH!" Liam yelped, dropping to his knees as pain shot up his arm.

She crouched down, her face inches from his.

Her smile never wavered, but her eyes were cold and empty.

"You know," she began conversationally, "I really hate being touched."

"L-let me go!" he stammered, his cocky confidence replaced with fear.

Scarlett ignored him, her eyes flicking to the bloodstain his fingers had left on her suit jacket.

"Do you see this?" She gestured to the faint smear of red on the pristine white fabric.

Liam's eyes darted to the stain, his face pale.

"Do you have any idea how much this suit costs?" she continued, her tone mocking.

"P-please, I..."

She slammed his hand against the desk, pinning it down with enough force to make him yelp again.

She then leaned in, her voice dropping to a whisper. "Thank your goodness, I have somewhere to be, so I'll take pity on you. But next time you think about putting your hands on me, ask yourself this—how many fingers do you really need?"

Liam's eyes widened, his mouth opening and closing like a fish out of water.

Satisfied, she released him with a shove.

He collapsed to the floor, cradling his wrist.

"I'll definitely report this to my father." He whimpered, quickly struggling off the ground and running out the class.

Scarlett rolled her eyes, standing up.

Adjusting her blazer, she glanced around the room.

"Anyone else want to test their luck?"

The classroom remained dead silent, every student frozen in their seats, wide-eyed and pale.

She smirked.

Her thoughts suddenly returned to Killian.

Without another word, she stormed into the hallway, her chest burning with a fury she could barely contain.

First, a Barbie doll, and now...what? piggytails?

He sure has a thing for mascots and she wasn't about to let it slide.

She looked around and spotted a nervous-looking boy loitering by the lockers.

As if sensing the gaze of a predator, the boy's eyes immediately darted around like a rabbit.

"Hey," Scarlett called out.

The boy froze, pointing a trembling finger at his chest. "M-me?"

"No, the janitor," she snapped, rolling her eyes. "Yes, you. Where did Killian go?"

He blinked rapidly, his Adam's apple bobbing. "I—I saw him head to the bathroom. With a girl."

Her jaw tightened. "Thanks for your help."

The boy gave a shaky nod, retreating as she turned on her heel and made her way to the bathroom.

From five steps away, she could already hear the faint sounds of giggling and soft moans filtering through the door.

Her blood boiled, her possessiveness erupting like a volcano.

So, after touching me, after fucking me, he thinks he can just...

She didn't dare finish the thought.

With a sharp exhale, she reached the bathroom door and slammed it open, the force echoing through the tiled walls.

What she saw inside made her blood run cold.

The pigtailed girl was sitting on the edge of the sink, her skirt raised up around her waist, her panties discarded on the floor.

Her legs were spread wide, exposing her pink, slightly hairy pussy, glistening in the dim light.

Killian stood between her legs, one hand on her breast, kneading it through her blouse, while the other was buried between her thighs, his finger moving in and out.

The girl let out soft moans, her head thrown back against the mirror, completely lost in the moment.

Neither of them noticed her even standing there.

Scarlett's eyes narrowed into slits, her vision tunneling.

So after already touching me with those hands, fucking me with that dick, he thinks he can just touch someone else?

Her fury swirled and twisted into something dark and uncontrollable.

Her heels clacked against the tiles as she marched toward them, her presence finally catching their attention.

The girl gasped, her head snapping up, eyes wide with shock. "W-who..."

Scarlett didn't let her finish.

"You have three seconds to get your filthy hands off him before I rip them off and shove them down your throat."

The girl froze, her trembling hands dropping from Killian's chest as she scrambled to pull her skirt down.

Killian turned, his brow furrowed in confusion. "Scarlett?"

"Don't," she snapped, her eyes locking onto his.

Her gaze flicked to the girl, who frantically collected her discarded panties and was prepared to leave.

"Did I say you could go?" Scarlett's voice was dangerously calm, her head tilting slightly.

The girl whimpered, backing up against the mirror.

Scarlett stepped closer, her lips curling into a cold smile. "You think it's fun to spread your legs for anyone who asks, huh? Let me give you some advice. Next time, don't pick someone who's already been...tainted."

"T-tainted?" the girl stammered.

Scarlett's smile widened, the malice in her eyes glittering. "You don't even want to know where his hands have been."

"Enough!" Killian's voice cut through the tension, his expression darkening. "What the hell is your problem?"

Scarlett's head jerked to him. "My problem?"

"You're acting like a psycho," he snapped. "This has nothing to do with you."

Her laughter echoed through the small space, cold and hollow. "Oh, Killian, you really don't get it, do you?"

He frowned, his confusion deepening.

She stepped closer to him, her finger pressing against his chest. "You don't get to ignore me, touch someone else, and then act like it doesn't concern me."

"What the hell are you talking about?" he growled, genuinely baffled.

She tugged him by the tie, making him lean closer, till her lips brushed against his ear. "Raise your hands to another girl again, and by the time they finish cleaning your blood off these walls, your entire family will be mourning you with one arm."

His eyes widened in shock.

Before Scarlett could say another word, a voice broke through the suffocating tension.

"Scarlett."

She turned sharply, her gaze landing on Mori, who was leaning casually against the doorframe, her hands stuffed in her pockets.

Scarlett's expression darkened. "I'm in the middle of something, kid."

Mori didn't blink. "And now you're not."

Before Scarlett could argue, Mori grabbed her wrist, her grip surprisingly firm as she tugged her toward the door.

"Let go," Scarlett hissed.

Mori ignored her, dragging her out into the hallway without so much as a glance back.

The bathroom door swung shut behind them, leaving Killian and the trembling girl in stunned silence.
