PAIRING: best friend!ni-ki Γ fem!reader
After seeing you laugh a little too closely with Jake, Ni-ki drags you home, ties you to his bed, and makes you beg for him until you forget anyone else exists.
β οΈ : explicit content - smut (mdni) including: bondage (wrist restraints), fingering, oral (f. receiving), edging, orgasm denial, overstimulation, degradation, possessive dirty talk, jealousy, begging, crying during sex, squirting, creampie, best friends to lovers, not proofread, (kinda ass ngl)
Your wrists are bound above your head with Ni-kiβs belt, secured tightly to the headboard. The cool leather bites into your skin every time you tug against it. Your legs are spread wide, knees pushed up toward your chest by his strong hands as he kneels between them, eyes dark with something dangerous.
βYou think itβs funny?β His voice is low, almost a growl. βGiggling like that with Jake hyung right in front of me?β
You shake your head quickly, breath already shaky. βWe were just talking, Ni-kiβ¦ heβs your friend-β
βExactly. My friend. And youβre mine.β He leans down, breath hot against your inner thigh before his tongue drags slowly through your folds. βOr at least you will be after tonight.β
A broken moan escapes you as he licks deeper, tongue flicking over your clit before sucking it into his mouth. Heβs always been playful, teasing; your tall, mischievous best friend. But tonight the jealousy has turned him possessive, almost feral.
He eats you out like heβs starving, long fingers joining his tongue, curling inside you and stroking that spot that makes your toes curl. Your hips jerk, chasing the pleasure, but he pins you down harder.
βStay still,β he warns, pulling back just as the coil in your belly tightens. βYou donβt get to cum until I say so.β
βNi-kiβ¦ please,β you whimper, already aching.
He smirks, lips shiny with your arousal. βAlready begging? Pathetic. I havenβt even started.β He slides two fingers back in, pumping slowly while his thumb circles your clit with maddening lightness.
He brings you to the edge again and again; his tongue, fingers, then pulling away completely each time you start to tremble. Tears prick at your eyes by the third denial.
βWhy are you doing this?β you sob, hips twitching uselessly in the air.
βBecause you need to learn who you belong to.β He reaches for the small vibrator heβd grabbed earlier and presses it against your swollen clit on the lowest setting. The buzzing sends electricity through your body.
Your back arches off the bed. βFuck- Ni-ki!β
He watches you intently, dark eyes locked on your face as you writhe. βLook at you. So desperate already. Bet Jake couldnβt make you cry like this.β
He turns the vibrator higher and pushes three fingers inside you, fucking you deep and fast while the toy buzzes relentlessly against your clit. The pressure builds impossibly fast.
βIβm close- please, Iβm so close-β
He pulls both away instantly.
You let out a broken sob, tears spilling down your cheeks. βI canβt- please let me cum, Iβll do anything-β
βAnything?β He climbs over you, sweatpants shoved down just enough to free his aching cock. He taps the head against your soaked entrance teasingly. βThen say it. Say youβre mine.β
βIβm yours, only yours, Ni-ki. Please, I need you inside me. Please. Please.β
Something shifts in his eyes, the jealousy melting into raw need. He pushes in with one deep thrust, stretching you open. A loud moan tears from your throat.
He fucks you hard, hips snapping against yours, the belt around your wrists creaking with every thrust. βThatβs right. Mine. Not Jakeβs. Not anyoneβs but mine.β
He reaches down and presses the vibrator back to your clit on high. The sudden overwhelming pleasure makes you scream, walls clenching around him.
βCum for me,β he growls, thrusting deeper. βMake a mess on my cock like the needy girl you are.β
You shatter hard. Your orgasm crashes over you, thighs shaking violently as you squirt around him, soaking his stomach and the sheets. He doesnβt stop, fucking you through it, chasing his own release.
βFuck - youβre so tight when you cum like that.β His pace turns erratic. With a low groan he buries himself deep and fills you with hot spurts of cum, hips stuttering as he rides it out.
He stays inside you for a long moment, breathing heavily against your neck. Then he gently unbuckles the belt, rubbing your wrists soothingly before pulling you into his arms.
βYou okay?β he whispers, voice softer now, pressing kisses to your tear-streaked cheeks. βIβ¦ I didnβt mean to be that rough. I justβ¦ seeing you with him made me realize I canβt keep pretending weβre just friends.β
You smile tiredly, curling into his chest. βTook you long enough, idiot.β
He chuckles, holding you tighter. βYeah. But youβre mine now. For real.β
