Devil in Disguise

Chapter 1: Temptation Next Door

I’ve always known Jungkook was trouble. The whole neighborhood whispers about him—calls him the devil. Rude, arrogant, a storm in human form with a smirk that could shatter hearts or start wars. Girls swoon over his chiseled jaw and those piercing, dark eyes; guys shrink when he walks by, all six feet of pure, intimidating muscle. But me? I’ve seen the other side of him. The shy, polite boy who blushes when I tease him, who clings to me like I’m his lifeline. He’s five years younger, sure, but we’ve grown up together, two misfits in a world that doesn’t quite fit either of us. To me, he’s just Kook—my adorable, bratty shadow.

His mom begged me to tutor him. 'You’re the top of your class, Y/N,' she’d pleaded, her eyes desperate. 'He’s failing everything. Please, help him.' I couldn’t say no, not when I’ve known him since he was a scrawny kid trailing after me with scraped knees and a toothy grin. Now, though? That scrawny kid is gone. Replaced by a man whose presence fills every room, whose voice—low and rough—sends shivers down my spine even when I pretend it doesn’t.

Tonight, he’s sprawled on my couch, textbooks forgotten on the coffee table as he whines about algebra. My apartment smells like the pizza we ordered, and the dim light casts shadows over his sharp features. I’m in my usual after-hours getup—tight tank top, shorts that barely cover anything, my dark, smoky eyes catching the light as I lean over to point at an equation. I know I’m a walking temptation; I’ve seen the way men stare, the way their eyes linger on my plump, bouncy curves, my swollen pink lips. But Jungkook? He’s different. He’s safe. Or so I thought.

'This is stupid, Y/N,' he grumbles, tossing his pencil down. His voice is a pout, but his eyes—God, those eyes—are locked on me, intense in a way that makes my skin prickle. 'Why do I even need to know this crap?'

I roll my eyes, straddling the line between tutor and friend as I nudge his shoulder. 'Because, brat, you’ll fail if you don’t. And then your mom will have my head. So focus.'

He smirks, leaning closer, his breath warm against my cheek. 'I’m focused. Just… not on math.' His tone dips, playful but edged with something darker, something I can’t quite place.

'Oh, really?' I challenge, arching a brow as I lean in too, my long lashes fluttering. 'What’s got your attention then, Kook?'

He hesitates, that shy boy peeking through for a split second before he grins, all teeth and mischief. 'You. Always you.'

My heart skips, but I laugh it off, shoving his chest—hard muscle under my palm. 'Flirt. Keep that charm for the girls at school. I’m immune.'

'Are you?' he shoots back, voice low, eyes dropping to my lips. '’Cause I’m not so sure. You’re blushing, Y/N.'

I scoff, but heat creeps up my neck. Damn him. 'In your dreams, kid.'

'Every night,' he murmurs, so quiet I almost miss it. But I don’t. And suddenly, the air between us crackles, heavy with something unspoken. He’s still on the couch, but he’s shifted closer, his knee brushing mine, his gaze hungry in a way I’ve never noticed before. Or maybe I have, and I’ve just ignored it.

'Jungkook,' I warn, but my voice is softer than I mean it to be. I stand, needing space, but he’s up in a flash, towering over me, all broad shoulders and quiet intensity. My tank top clings to me, and I’m hyper-aware of how my nipples—pink and puckered—press against the fabric under his stare.

'Don’t play innocent, Y/N,' he says, stepping closer, his voice a growl now. 'You know what you do to me. You’ve always known.'

I should push him away, laugh it off again, but my breath catches. 'And what do I do, huh? Enlighten me.'

His lips curl, devilish, as his hand hovers near my hip, not touching but close enough to feel the heat. 'You make me hard just by existing. Every damn day. And I’m tired of pretending I don’t want you.'

The words hit like a punch, raw and filthy, and I feel a rush of heat between my thighs, my pussy clenching at the confession. I’m not some damsel to be seduced, though—I’m Y/N, the woman who doesn’t back down. So I tilt my chin up, meeting his gaze with fire. 'Careful, Kook. Say shit like that, and I might make you prove it.'

His eyes darken, and before I can blink, he’s on me, hands gripping my waist as he backs me against the wall. His body is all hard lines and heat, and I can feel him—fuck, I can feel how hard he is already, pressing against my thigh. 'Try me,' he whispers, lips brushing my ear. 'I’ve been dying to taste you.'

My hands slide up his chest, nails digging in just enough to make him hiss, and I smirk. 'Then what are you waiting for, devil?'
