Special R18 Chapter: In the Heat of Obsession (Mikasa)

[The room is dimly lit, shadows dancing against the walls as the candlelight flickers. The air is thick with tension, with something far more primal simmering just beneath the surface.]

---

She stands before me, her obsidian hair cascading down her back, her breathing uneven. Her body is tense, but it isn't fear that stills her—it's anticipation. That same obsession I've seen in her eyes every time she looks at me, the same fire that's been burning between us, unspoken but undeniable. Tonight, I'll make sure she understands exactly what she belongs to.

I take a slow step forward, and she doesn't move away. If anything, her lips part slightly, her pupils blown wide. My fingers reach out, grazing the bare skin of her neck before gripping the scarf wrapped loosely around her throat.

I tug—hard—and she stumbles forward, crashing into my chest.

A sharp intake of breath. A quiet gasp.

"Mikasa." My voice is low, commanding. She shivers.

"Y-yes?"

I grip her chin, tilting her head up to meet my gaze. Those stormy gray eyes, usually so cold and calculating, are filled with something raw, something desperate. I smirk, leaning in just enough for my lips to brush against hers, but not enough to give her what she wants.

"You've been watching me," I murmur, voice dark with amusement. "Haven't you?"

Her breath hitches, but she doesn't deny it. Instead, she nods, her fingers twitching as if resisting the urge to reach for me. "Always," she whispers.

I chuckle, my grip on her scarf tightening as I pull her even closer. "Obsessive little thing." My free hand trails down her back, gripping her waist, feeling the way her body trembles beneath my touch. "You want me to take you, don't you?"

Her hands finally move—gripping the fabric of my shirt, her knuckles white. "Please," she breathes, the word barely audible.

That's all I need.

I crash my lips against hers, claiming her in a kiss that is nothing short of possessive. She responds instantly, matching my intensity, her fingers tangling in my hair as if she can't get close enough. I push her back, guiding her until her knees hit the mattress.

She falls onto it, her breath coming in short, desperate pants as I crawl over her, pinning her wrists above her head with one hand.

She struggles—not to escape, but to test me. I smirk, leaning down to press my lips against her jaw, then lower, biting down just hard enough to leave a mark. She lets out a small, needy whimper, arching against me.

"You're mine," I growl against her skin, my free hand trailing lower. "Say it."

Her breath is shaky, but her voice is firm. "I'm yours."

I reward her with another searing kiss, devouring her, taking what's mine. Her legs wrap around me, her body pressing against mine in a way that leaves nothing to the imagination.

As I claim her mouth in a bruising kiss, my cock throbs against her hip, aching to be buried inside her. I grind against her, letting her feel how hard I am for her, how desperately I crave her.

Breaking the kiss, I trail my lips down her neck, nipping and sucking at the tender flesh. "Tell me where you want it," I demand, my voice rough with lust. "Want me to fuck you with my tongue first, or do you need my dick inside you now?"

She whimpers, writhing beneath me, her hands fisting in the sheets. "Please, just...fuck me," she begs, her voice barely coherent. "I need it. Need you."

With a growl, I position myself at her entrance, the head of my cock nudging against her slick folds. "Look at me,"

I command, my gaze locking with hers as I slowly push inside her, savoring the tight, wet heat that envelops my shaft.

Her eyes flutter closed, a silent scream of pleasure etched across her face. I pause, giving her a moment to adjust, relishing the way her inner muscles clench around me.

Then, with a deliberate thrust, I bury myself to the hilt, a guttural groan tearing from my throat at the exquisite sensation of being fully sheathed within her.

"Fuck, Mikasa," I hiss, my hips rocking gently as I begin to move, setting a slow, deliberate pace designed to drive her wild. "So fucking tight. So perfect."

Her nails dig into my shoulders as I start to move, each thrust driving deeper, harder. The bed creaks beneath us, the rhythm of our coupling filling the room.

"Mmm, yes," she moans, her hips rising to meet mine. "Just like that. Don't stop."

I lean down, capturing her lips in a fierce kiss as I pick up speed, pounding into her with increasing urgency. The slap of skin against skin echoes through the chamber, punctuating the lewd sounds of our passion.

"You're squeezing me so goddamn tight," I grunt against her mouth, my balls slapping against her ass with every powerful stroke. "Gonna fill this pussy up soon."

She breaks the kiss, her head thrown back in ecstasy. "Do it! Cum inside me!"

With a final, brutal thrust, I bury myself to the root, grinding against her as I explode, painting her insides with my hot seed.

"Ahh, fuck!" I roar, my vision blurring as wave after wave of intense pleasure crashes over me. I can feel her milking me, her inner walls rippling around my pulsing cock, drawing out every last drop.

As the aftershocks subside, I collapse on top of her, both of us panting heavily, sweat-slicked bodies entwined. I nuzzle into her neck, pressing soft kisses to the marks left by my teeth.

"That was incredible," I murmur, my voice husky with satisfaction. "You're amazing, Mikasa."

She turns her head, meeting my gaze with a dazed smile. "You're not so bad yourself,"

I chuckle, rolling off her and onto my side, pulling her close so she's nestled against my chest. Our hearts still race in tandem, a physical manifestation of the intense connection we share.

"I think we've established that we're quite compatible," I remark, tracing idle patterns on her arm with my fingertips. "But I'm curious...what made you decide to act on these feelings tonight?"

Mikasa's expression turns thoughtful, her gaze drifting to some point beyond the candlelit room. "I realized I couldn't keep pretending anymore," she says softly. "Watching you, wanting you...it consumed me. And I couldn't bear the thought of losing you as a friend because of my desires."

I tilt her chin up, forcing her to look at me. "You could never lose me, Mikasa. Not unless you pushed me away."

She shakes her head, a hint of defiance in her eyes. "No, I won't let that happen. We're stronger than that."

I nod, a sense of determination settling over me. "We are. And now that we've crossed this line, there's no going back. But I promise you, Mikasa, I'll cherish this newfound intimacy between us. We'll navigate whatever comes next together, as equals."

She searches my face, seeming to find the sincerity she seeks. "Together," she repeats, a soft smile playing on her lips.

I capture her mouth in a gentle kiss, pouring all my devotion and affection into it. When we break apart, I rest my forehead against hers.

"Rest now, love. We've earned it."

As exhaustion washes over us, I guide Mikasa to lie back against the pillows, tucking her into my embrace. Her body molds perfectly against mine, a fit so natural it's as if we were made for each other.

I stroke her hair, listening to her heart's steady beat, feeling her chest's rise and fall against mine. In this peaceful moment, surrounded by the aftermath of our passion, I realise just how deeply I've fallen for her.

Sleep eventually claims us, and our intertwined forms a picture of contentment. As I drift off, I know that no matter what challenges may arise, Mikasa and I will face them together, our bond forged in the flames of desire now tempered by the warmth of love.
