    Worst Behaviour

    Complete
    cloudtransprncy12h ago

    She just finished getting ready for the club, but she's giving you that look. There's no way you're letting her walk out that door.

    76

    Fuck.

    She's looking at you with that same look again. That half-lidded gaze that makes your cock twitch in your pants. Karina's sprawled on your couch like she owns the place, that sparkly see-through dress barely covering anything important. Her dark hair spills over her shoulders, and those full lips are slightly parted like she's waiting for you to do something about it.

    You've been trying to keep it together all night. But how the hell are you supposed to concentrate when she looks like that?

    "Why do you keep looking at me, babe?" she asks, voice honey-sweet but with that edge that tells you she knows exactly what she's doing. Her legs shift slightly, the dress riding up just enough to drive you fucking insane.

    Every time she moves, those little crystals on her dress catch the city lights shining through your windows. She's glowing brighter in your living room than she would under any club strobe light, the view all yours instead of being on display for strangers to want what they can't have.

    "Why do you keep looking at me like that?" she repeats, biting her lower lip.

    That's it. You're done playing this game.

    You cross the room in seconds, grabbing her by the face. Her skin is so soft under your rough hands, warm and smooth like silk. You crash your lips against hers, feeling her melt instantly.

    When you pull back, her lipstick is smudged. Good.

    "Call your girls," you growl against her mouth. "Tell 'em you ain't gonna make it tonight."

    Her eyes flash with excitement as she reaches for her phone.

    …

    The couch is creaking so loud her moans are probably echoing through the entire building, but you couldn't give less of a fuck. Fuck the bed—you don't need it. The couch is your playground tonight, and you're sure as hell gonna break it.

    Karina's dress is shoved up around her waist, her tits spilling out from the top where you yanked it down, her panties pushed to the side because you couldn't wait to get inside her. The champagne-colored fabric bunched around her middle only makes her naked skin look more delicious by contrast.

    "Fuck, you're so wet," you groan, feeling her pussy grip your cock like it was made for you. Her walls are squeezing you tight, hot and slippery as you pump into her. You take it slow at first, savoring the way her body accepts you inch by inch, the way her breath catches when you're fully seated inside her.

    "Been thinking about this all day?"

    "Yes," she gasps, her voice breaking as you hit deeper. Her mascara is already starting to smudge at the corners of her eyes. "Wanted you to see me in this dress and just—ah!—lose it."

    You pull back until just the tip of your cock is teasing her entrance, watching her face as she whimpers, trying to pull you back in. When you slam back in, the sound she makes is almost inhuman.

    One hand digs into her waist, feeling the contrast between the smooth fabric and her even smoother skin. Your other hand presses her thigh open wider, spreading her legs so you can watch yourself disappear inside her over and over. The visual is hypnotic—your cock glistening with her arousal each time you pull out, her pussy lips stretching around your thickness, clinging to you like they don't want to let go.

    "Look how pretty your pussy is," you tell her, staring down at where you're connected. Her waxed lips are puffy and pink, stretched around your thickness. Every time you pull out, you're coated in her juices, a string of wetness connecting you to her even when you're apart. "So fucking wet for me."

    You maintain a steady rhythm, watching her face contort with pleasure as you hit that spot deep inside her that makes her toes curl. Her lips part in a silent scream, eyes unfocused as she surrenders to the sensation. You can feel the pressure building at the base of your spine, but you fight it off. Not yet. Not nearly yet.

    Karina's eyes flash with something dangerous as she suddenly grabs your neck from underneath, pulling you down to her level. Her nails dig into your skin, not enough to hurt but enough to remind you she has claws.

    "Spit in my mouth," she demands, her tone leaving no room for negotiation. "Fucking now."

    You oblige, letting a string of saliva fall between her parted lips. She watches it descend with hungry eyes, her tongue darting out to catch it. When it connects, her eyes roll back, a shudder running through her entire body. She's on her worst behavior tonight—and you're right there with her.

    Your thrusts become deeper, more deliberate, each one punctuated by the wet sound of your bodies connecting and the sharp slap of skin against skin. The couch cushions shift beneath you, creating new angles that make her gasp and claw at your shoulders.

    "Pull my hair," she orders next, her perfect tits jiggling with each thrust as she arches her back. The crystal embellishments on her dress catch the light with each movement, creating a dazzling display across her skin. "I wanna feel you take control."

    You tangle your fingers in her dark hair, wrapping it around your fist before yanking just hard enough to expose the delicate line of her throat. Her pulse flutters visibly under her skin, rapid and strong. Her eyes light up with approval, pupils blown wide with desire.

    You bend down to taste her exposed neck, dragging your tongue from her collarbone to her jaw, tasting salt and expensive perfume. Her skin pebbles with goosebumps in the wake of your mouth.

    "That's it," she moans, one hand reaching down to rub her clit while you fuck her. Her fingers move in tight circles, pressing and releasing in time with your thrusts. Her other hand reaches between your bodies, cupping and squeezing your balls with just the right pressure. "Fuck me like we're the last two people on fucking earth."

    You slide two fingers into her mouth, and she sucks them like she's starving for it, eyes never leaving yours. Her tongue swirls between your digits, getting them soaking wet. When you pull them out, a trail of saliva connects her mouth to your hand before breaking.

    "Slut me out," she begs, her voice husky and raw. "I'm your whore tonight. Use me up."

    Her words hit you like a physical force, sending a jolt of electricity straight to your cock. You feel yourself somehow get even harder inside her, stretching her walls further. Her eyes widen, feeling the change.

    "Fuck, you get so big when I talk dirty," she gasps, a proud smile playing on her lips despite her compromised position.

    Her words make you snap your hips harder, the sound of skin slapping against skin filling the apartment along with the wet squelching noises from her soaked pussy. The obscene soundtrack echoes off the walls, filthy and perfect.

    "Yeah? You like being my little whore?" You grip her face, thumb pressing into her cheek, making her look at you while you rail her. "Like it when I fuck this tight pussy?"

    "Yes! God, yes!" Her nails rake down your back, definitely leaving marks you'll feel tomorrow. Her legs wrap around your waist, pulling you deeper. "Don't stop, please don't stop!"

    She suddenly braces her hands against your chest, pushing with unexpected strength. You're about to ask what's wrong when she speaks.

    "I want to ride you," she says, voice thick with need. "Let me show you how bad I can be."

    The sight of her taking charge sends a fresh wave of desire through you. You grip her waist, helping her as you both shift positions without disconnecting your bodies. The movement causes your cock to hit new angles inside her, drawing a long, shuddering moan from her throat.

    For a moment, you're mesmerized by the view—Karina straddling you, dress bunched around her waist, perfect tits bouncing freely, her body flushed and glistening with sweat. Her hair cascades down her back in wild waves, and her lipstick is smeared across her face from your kisses. She's never looked more beautiful.

    She places her hands on your chest for leverage and starts to move, rising up until just the tip of your cock remains inside her before sinking back down with agonizing slowness. Her eyes flutter closed as she takes you to the hilt, a soft "fuck" escaping her lips.

    "My turn," she pants, finding her rhythm as she rides you. She grinds her hips in circles that hit spots inside her that make her whole body shudder. "Gonna use you now."

    You grab her ass, spreading her cheeks as she bounces on your cock, feeling the firm muscle flex under your palms with each movement. Her tits sway hypnotically with each rise and fall, and you can't resist anymore. You sit up slightly, capturing one perfect nipple in your mouth, swirling your tongue around the hardened peak before sucking hard.

    "Oh god," she cries out, her pace faltering as pleasure overtakes her. Her fingers tangle in your hair, holding your mouth against her chest as you worship her breasts, moving from one to the other. "Yes, just like that."

    You cup both tits in your hands, feeling their perfect weight as you alternate between licking, sucking, and gently biting her sensitive nipples. She's become a complete mess—hair wild, makeup smudged, dress twisted around her body, eyes unfocused with pleasure as she continues to ride you with increasing desperation.

    Her movements become more erratic, her thighs trembling with the effort of lifting and lowering herself.

    You can tell she's close, her breathing coming in sharp, quick gasps, her pussy fluttering around your cock with the beginning of her orgasm.

    "I'm gonna cum," she whimpers, her body tensing as her rhythm falters completely. "Fuck, fuck, I'm cumming!"

    Then, you feel her pussy clenching around your cock, squeezing you with an intensity that nearly pushes you over the edge.

    Her back arches dramatically, head thrown back, exposing the elegant line of her throat as she cries out. Her entire body trembles, thighs quivering against yours as the orgasm washes through her.
