82 — The Monster that Sleeps Inside that Beauty (NSFW)

Mia's POV:

The knock on her bedroom door was unexpected. Mia, lying on her stomach on her bed, scrolling aimlessly through her phone, grumbled. "What?"

"It's me. Jae-il."

Mia's head shot up. She dropped her phone. A wide, predatory grin spread across her face. She scrambled off the bed and practically flew to the door, yanking it open. "You little shit! You came back!"

And there he was. Her little brother. Standing in her doorway, looking unfairly handsome even with his hair damp from the rain. He held up two more small, gift-wrapped boxes. "One for you, one for Su Ah Noona. Thought I'd drop them off before heading back."

Mia’s eyes zeroed in on the gifts, but only for a second. Her focus was all on him. On the slight dampness of his coat, the way his dark hair curled and fell over his purple eyes, that chiseled curve of his jawline. "You should've called, you bastard. I would've... prepared."

A slow, knowing smirk tugged at the corner of his lips. His eyes crinkled. "Prepared for what, Noona?"

"You know damn well what for." She shot back, her voice a low purr. She reached out, grabbed him by the lapels of his coat, and pulled him into her room, kicking the door shut behind them. Still holding her little brother with an iron grip, she violently pushed him towards the bed.

Jae-il's eyes widened slightly, his smile all too telling. "Wait, Noona. Let me tell you something. Let me tell you some—" He fell onto the bed, bouncing a little on the mattress. "—thing."

Mia ignored the gift boxes that fell from his hands. She followed him down, crawling onto the bed, straddling his hips in one fluid, predatory motion. She pinned his wrists above his head with her hands, leaning over him, her blonde hair creating a curtain around their faces.

"It's not about the gift. And it's not about your something." Her voice was thick with lust. "You left me unsatisfied, you bastard. You left me aching for weeks. And now you dare show up here, smelling like rain and looking like this, and expect me to just... what? Thank you for the gift?"

That damn bastard blinked innocently, a breezy smile on his face. "Well, I put a lot of thought into it. It would be really kind of you to, you know, show some gratitude."

Mia’s nostrils flared. She wanted to wipe that smug look off his face. She wanted to kiss him until he couldn't breathe. She wanted to do both. And more. "I'll show you gratitude." She growled. "I'll show you so much gratitude you won't be able to walk straight tomorrow."

"Promises, promises..."

That was it.

She crashed her lips against his.

It wasn't a gentle kiss. It was a collision. A clash of teeth and tongues. She dragged her mouth down, clamping his bottom lip between hers, biting, not hard enough to draw blood, but hard enough to make him groan.

He kissed her back with the same ferocity, biting her lip with that same intensity.

A low, guttural sound vibrated in his chest.

She could feel him hardening beneath her, the thick ridge of his erection pressing against her core through the layers of their clothes.

She ground her hips down against his, a slow, deliberate roll that had them both gasping into each other's mouths. Within seconds of her straddling him, she was more humid than the monsoon weather that had ravaged the city a few hours prior. A slow, seeping dampness that coated her inner thighs and soaked through the fabric of her panties. He could probably feel it.

She hoped he could.

Her hands released his wrists, moving to frame his face, her thumbs stroking his jaw. She tilted her head, deepening the kiss, her tongue slithering wherever it could reach. He was a drug, and she was a hopeless addict. She had her first hit a few weeks ago and had been in withdrawal ever since.

Now, she was getting her fix.

His hands, now free, roamed her body. They slid down her back, gripping her ass, pulling her tighter against him.

"I fucking hate you." She panted, breaking the kiss just enough to speak, her lips still brushing against his. "For leaving me like that. For making me want you this much."

"Then you must hate yourself for loving it so much." Jae-il didn't miss a beat, his voice a rumbling amused note that sent a fresh wave of desire pooling in her belly. He bucked his hips up, a sharp, powerful thrust that had her seeing stars. "Is that what you want, Noona? For me to leave you wanting more? Is that what makes it so good?"

"You damn bastard...." Mia's voice was a ragged moan. She pushed herself up, her hands flat on his chest, her hair falling over her face. She looked down at him. "You talk too much."

And then she was moving. She shifted back, her hands fumbling with the buttons of his jeans. He watched her for a moment, before removing everything else.

She finally got it open, her fingers brushing against the hard length of him, straining against the denim.

He hissed, his hips jerking.

With a triumphant little growl, she tugged his jeans and boxers down just enough to free him. His cock sprang up, hard and proud. Her breath hitched. She'd forgotten... no, she'd tried to forget just how magnificent he was. How perfectly shaped, how thick and long and heavy. He was beautiful.

She wrapped her hand around him, marveling at how a single hand was hardly enough to hold him. And by the divines, he was hot, impossibly hot, and velvety smooth. The prominent vein that ran along his shaft throbbed deliciously. She gave him a slow, experimental stroke, from base to tip. A bead of pearly fluid gathered at the slit, and she swiped it away with her thumb, spreading the slickness over the head. He groaned, his head falling back against the pillows.

"Like that, Noona..." He breathed, his voice breezy with pleasure. "Just like that."

Mia leaned down, puckering up her lips before a glob of saliva dripped onto the swollen, angry red head. He shuddered, his hands fisting in the sheets. "Fuck..." She used her hand to spread her spit all over his shaft, coating him until he was glistening. "Noona..."

"Shhh."

She shushed, giving him a heavy-lidded, mischievous little grin.

"What shhh. You're jacking me off so good." He chuckled. "And you tell me to be quiet."

"You want mom and Su Ah to hear how you're moaning like a little bitch for me?" Mia giggled. Her hand moved with more confidence now, her strokes becoming faster, more firm. She twisted her wrist on the upstroke, her thumb grazing the sensitive underside just below the head. Shit, she was getting the hang of this, actually. "Wouldn't that be something? Them bursting in here to see what all the fuss is about? Seeing their precious Jae-il with his dick out, getting a handy from his dear older sister?"

She fluttered her eyelashes rapidly, a cute, amused pout curling her lower lip.

He groaned, his eyes rolling back in his head. "You're evil, you know that?"

"Only to you."

"Besides, I don't fucking moan. I groan." He let out a breathy grunt. "There's a difference."

"Not from where I'm sitting." Mia teased, leaning down to flick her tongue against the tip. He tasted of salt and something uniquely, deliciously him. "And you are moaning."

She took him into her mouth then, just the head at first, swirling her tongue around the crown, lapping at the slit.

He bucked his hips, resting his hand on her head, nudging her further down. She obliged; she'd have impaled herself on his cock even if he hadn't. Slowly, his impressive shaft began to disappear beyond the confines of her tight, wet oral cavity. The more Jae-il slipped in—wrapping his cock in that pretty cock socket that was his Noona—the more he groaned.

God! She loved this. The feeling of him in her mouth, the weight of him on her tongue, the sounds he made. It was a power trip. It was a validation. It was a sin.

And it was all hers.

She bobbed her head up and down, her saliva coating him, making the slide slick and easy. Her hand worked in tandem with her mouth, stroking what she couldn't take, her fingers tightening and loosening with each pass.

He tightened his hold on her hair, digging his nails, almost threatening to rip her hair off. The slight sting only served to heighten her arousal, because he must've slowly beginning to lose control of himself.

The faint, dull ache of his grip in her hair made her feel desired. It made her feel possessed. It made her feel… powerful.

She took a deep breath and went down, taking him as deep as she could. She felt the head of his cock nudge the back of her throat, and she forced herself to relax, fighting the urge to gag. His entire body went rigid, a guttural moan tearing from his lips. "Noona... fuck..."

Mia held him there for a moment, her nose buried at his base, breathing through the slight bit of air she could get. Her eyes watered from the strain and the sheer intensity of the sensation. Then, slowly, she pulled back, her lips dragging along his length, her tongue stroking the underside as she went.

She popped off with a loud, wet sound, a string of saliva connecting her lips to his flushed, glistening cock.

"Heh, do you like it, little brother? You like it when your Noona chokes on your—"

Mia's eyes widened abruptly when Jae-il, holding onto her hair like he would a leash, pushed her back down onto his cock, a sharp, powerful thrust that had her sputtering. He wasn't just letting her take the lead anymore. He was fucking her mouth. Her eyes rolled back as he set a brutal pace, his hips pistoning up, his cock driving deep into her throat with every thrust. He shifted, moving upright, as if laying down and enjoying it wasn't an option anymore.

Tears streamed down her face, mixing with the saliva that dripped from her chin. She couldn't even hold back the gag reflex noises she made now, lewd, wet, and messy. The sound of him using her mouth was obscene. Wet slurps and guttural groans filled the room.

Her eyes trembled—for a moment, all they caught was the hard ridge of his abs, the proud swell of his chest, the taut column of that throat, and… his own eyes. Murky, with an unnatural, self-indulgent glow.

"You talk too much too, Noona." He grunted, his voice strained with pleasure, and just the right amount of cockiness. "Maybe a little punishment will teach you to be a good girl for your little brother."

Mia’s mind went blank. All she could do was hold on, her hands gripping his thighs for dear life as he used her throat like a cheap fleshlight. She coughed, sputtering, drooling all over him and herself. Her pussy clenched. She was so wet she could feel it soaking through her shorts. One of her hands disengaged from the hard muscle of his thigh and snaked downwards, slipping under the waistband of her shorts and panties.

The first touch of her own fingers against her slick, swollen folds sent a jolt of pure electricity through her. She was drenched. Her clit was a hard, throbbing nub, begging for attention. She didn't hesitate. She began to rub it in tight, fast circles. Her hips bucked involuntarily.

Jae-il didn't stop his relentless assault on her throat.

"Ghkkk!"

"Ghkkk!"

"Argh! Ghkkk!"

Mia sputtered with every thrust, gagging. This was degrading. It was filthy. It was wrong. And it was the most fucking amazing thing she had ever experienced.

Her orgasm hit her like a wrecking ball. A car crash. A plane diving down into a fireball. It was a sudden, violent explosion of pleasure that started deep in her core and radiated outwards, consuming her entire being.

Her vision went white. Her entire body went rigid, then began to convulse uncontrollably. She moaned around his cock, the sound muffled, vibrating through his length.

He shuddered, his grip on her hair tightening to the point of pain. He held her down, his cock buried deep in her throat. His pace accelerated to the point where Mia's body just sort of went limp, completely at the mercy of the man who was now basically using her like a pocket pussy.

With a brutal, final thrust, he sheathed his mast all the way down Mia's aching esophagus.

Then, he stilled. A stifled grunt rumbled from deep within his chest. A series of deep, violent throbs pulsed down the length of his cock, followed by the feeling of warm, thick seed shooting straight down her throat.

She didn't even have to swallow. It just went down.

And down.

And down.

And just when she thought he was done, another thick spurt would follow.

Jae-il's grip on her hair loosened, and he fell back down against the pillows, his chest heaving.

When his cockhead popped past her lips, freeing her of its suffocating weight, a gasp for air escaped her lips.

A thick string of saliva and cum connected her mouth to his cock. She looked up at him, her face a mess. Drool. Tears. Snot. And his cum, which had trickled out of the corners of her mouth and down her chin.

Jae-il, breathing heavily, looked back at her, his eyes dark with a satisfaction that was almost terrifying.

Mia collapsed onto him, her face buried in his chest, her body still trembling with the aftershocks of her own intense orgasm.

"Bastard." She lightly hit his chest with a trembling fist. Once. Twice. "That actually fucking hurt."
