Part 1 || Part 2
He sees how Sett always looks at your ass when he happens to be behind you. How his eyes linger on your lips after you laugh at something funny he said. Kayn sees how your fingers seem to brush against Sett’s whenever you hand him something. How you bite your lip to try and hide the flustered grin on your face when Sett takes off his shirt or compliments you. Please. Kayn isn’t oblivious to the sum of little hints that continue to add up.
If he’s being truthful with himself, he’s been wondering what Sett’s massive hands feel like around his neck and wrists, or how they’d look wrapped around your own pretty neck. Your hips even. Hell, if he were honest with you, he’d tell you as much. That he wants to see your eyebrows furrow as you sink down on Sett’s cock, how the stretch burns even after so much prep they did with you. Each taking turns using their thick fingers to spread you apart, bending you however they saw fit.
To his surprise, you want to fuck Sett just as much as he does. He grins slyly, you’re so shy about your wants, your desires. It’s cute, really. He pulls you to him for a rough kiss, teeth and tongue clashing hungrily. His tongue piercing runs over your plush lower lip as his fingers twitch and pull against the fabric of your clothing to try and bring you even closer to him.
He makes a game of it, chasing your almost naked figure down the hallway to Sett’s room, glad nobody else is home to see what mischief you’re both up to.
He grabs at you, pulling you close to him as you both fall onto Sett’s unmade bed. It’s comfortable, you think, lined with stuffed animals, still warm and smells like him. His mattress and blankets are so plush and cozy, too, you’d love to nap here. You don’t have long to think about snuggling with the boys before Kayn attacks you with tickles. His fingers graze against your sides as his teeth nip softly against the skin of your neck. You giggle, trying to keep your voice down and softly pushing against his chest, his fingers still tormenting your sides.
Finally, he settles down, smiling smugly against your neck as he wraps his arms around you. He rolls over, pulling you on top of him, your lips colliding with his where they belonged. You sighed against him, melting into his embrace as his tongue glides over yours.
“Ahem,” Sett’s voice rumbles from where he stands in the doorway, towel draped around his hips, hair still dripping from his shower. You pull away from Kayn nervously, sitting up on the bed with Kayn still underneath you, propping himself up on his elbows breathlessly, smiling mischievously over at Sett. His eyes trail over the both of you slowly, trying to figure out what’s going on without making any assumptions. He clears his throat again, “w-what are you two doing in here?” The grip on his towel tightens, his face remaining neutral.
“Now you’re playing hard to get, huh?” Kayn winks over at the redhead in the doorway. He grabs your chin and turns your face towards Sett, a deep blush covering your cheeks as you bite your lip. Sett swallows thickly. “She’s pretty, huh? A real good girl, too…” He smiles devilishly at you, tongue darting out to wet his lips before his gaze returns to the redhead. His eyes look lust-blown, his grip on his towel so tight his knuckles are white. Kayn’s voice drops an octave, “You wanna touch her, don’t you?”
Sett gives a small nod, his eyes never leaving your body. His ear twitches impatiently. Kayn gestures for him to come over, still holding your chin in his hand firmly. You watch as Sett closes the door behind him, taking slow steps towards you, unsure if this is real and not wanting to show just how eager he is. Your eyes scan his abs and chest slowly as he approaches, muscles flexing with each step. You eagerly lean up a little once he’s close enough, the pink-haired male dropping his hand from your face.
“Tsk tsk,” Kayn says softly, pulling you by your hair so his lips tickle the shell of your ear. “No kissing.” He bites his lip with a grin when you whine quietly, your plush lips forming a small pout. “Oh, what’s this? You thought there wouldn’t be any rules, beautiful?” He grabs Sett’s hair and pulls him down to be eye level with the two of you, speaking sternly to the male, “no marking her either.” He places a teasing kiss on Sett’s lips before continuing, “and if you get cum anywhere near her perfect pussy, I’ll beat the shit out of you.” His voice holds a teasing lilt, but no one in the room doubts how serious he is. The two males kiss again, tongues darting out to taste each other as Kayn keeps his grip on your hair. Your breath hitches as you watch them, chest tight with jealousy.
You get to work nibbling Sett’s neck, tasting the water droplets on his skin. His thick fingers thread through your hair tenderly, drawing you closer to him as he sighs against Kayn’s lips. You lick a trail up his neck to his jawline, your fingers gripping the yellow collar around Kayn’s neck to tug him to you. He smiles against your lips, loving when you take what you want from him.
Sett keeps his fingers busy, gliding over your back so softly that a shiver runs down your spine, a sound almost inaudible escaping your lips. His arms wrap around you loosely, large hands coming up to cup your breasts as he places open mouthed kisses across your shoulders. You shudder, leaning back against his chest. Kayn places his hands on top of Sett’s, encouraging him to squeeze your soft mounds a bit harder.
“I’ll let you taste her, Sett~” he pushes you onto your back on the bed next to him, kissing a line gently down from your lips to your breasts, tongue flicking against your perky buds before continuing his path downwards. Sett watches you eagerly, the way your chest rises and falls in anticipation, the way Kayn nibbles your inner thighs as his fingers loosely grip the sides of your black, lacy panties. Your breath hitches when you feel Kayn’s warm breath on your covered pussy, his tongue ring catching your clit just right even through the fabric. He begins to slide your panties down agonizingly slowly, his dual-coloured eyes meeting yours with an impish grin, the flat of his tongue still licking upwards against the fabric. Sett’s fingers slide between yours, holding your hand as the other male continues teasing you. Murmured sighs escape your parted lips as you watch Sett drop down to his knees next to Kayn, helping you out of your undergarment. The red-haired male leans forward as Kayn continues licking teasing stripes against your now exposed folds. His tongue pokes out experimentally to taste your nectar with Kayn’s saliva, a groan falling from his lips at how sweet you are. He kisses the pink-haired male again, this time including your folds in the mix with teasing licks from both of them.
A soft whimper escapes you as your hips buck up gently against their mouths, wanting more friction, more anything, really. Sett finally smiles up at you, eyes glimmering, as he squeezes your hand reassuringly. Kayn chuckles softly, moving up your body slowly, leaving damp kisses in his wake before reaching your neck. Sett settles in between your thighs, focusing solely on you and the way you moan and sigh from his and Kayn’s lustful caresses. His arms wrap under your legs, holding your hips still and your thighs against his cheeks as he makes love to you with only his mouth. He moans against you, your warmth and wetness absolutely intoxicating him as he sucks firmly on your clit, his tongue flicking in little circles against the sensitive pearl as his muscular arms squeeze your legs securely.
Kayn cups your breast, thumbing over your delicate nipple as he bites down on your neck, drawing a loud whine from you as you pant from the stimulation. He grinds slowly against your hip, the fabric of his annoyingly-still-on underwear already a little damp from the pre oozing from his painfully hard cock.
Sett’s free hand snakes over to Kayn’s hips, rubbing small circles over his skin while he continues eating you out. His fingertips trace the top line of Kayn’s waistband, tickling his skin softly. The male above you kisses you hungrily, drooling onto your chin as you moan and tremble against him from Sett’s ministrations. Gods, Sett was so good at this…
Kayn stands up abruptly, slightly startling you and Sett in the process, and rips off his underwear. His cock smacks against his abs angrily, a thick string of pre snapping from the loss of the annoying fabric. He pulls Sett away from you slightly, accidently (or maybe on purpose) tearing away your orgasm. You whine at him, tears pricking your already glazed over eyes. He ignores you with a small smirk, bending down to grab Sett by the neck for a hungry kiss.
He looked so sexy like this. Both of them, really. So enthralled with you and each other at the same time.
When you finally decide to stop staring, you sit up on the edge of the king-sized bed. Your fingers slip underneath the towel still wrapped around Sett’s waist to undo the fold, the rough, yellow fabric dropping to the floor and exposing his aching and girthy hard-on. You knew he’d be big, but honestly, the size of his cock is intimidating. An angry red tip leaking with pre, girthy enough you can barely fit your little hand around him when you paw at him.
He hisses against Kayn’s mouth, sucking on the other male’s tongue when your fingers finally wrap around him, him in one hand and Kayn in the other. Both men groan loudly when you begin pumping their lengths firmly, bringing both of their tips to your tongue for lustful little kisses. Kayn brings one hand down to your hair, gripping tightly as his hips thrust shallowly into your hand, moaning slightly louder when his eager tip bumps against Sett’s.
“F-fuck…” Sett moans into the other male’s mouth breathlessly, giving his hair a gentle tug and his lip a tender bite.
Kayn chuckles softly upon realizing that this is Sett’s first time with you. He turns and pushes the red-haired one onto the edge of the bed roughly. “Go ahead, beautiful, show Sett what a good girl you are.” You can hear the teasing smirk in his voice as you move eagerly to sit on the floor between Sett’s legs, your chin resting on his knee as you pull your bottom lip between your teeth. His lust-blown gaze meets yours, a small nod of approval just for you present with a wink, flashing his most charming smile at you.
He’s already making you feel so weak in the knees.
Kayn gives you a lingering kiss on your lips before you lean forward, tongue poking out to give Sett a few kitten licks on his sensitive tip. The pink-haired one helps you out, pulling your hair back and holding it out of your face for you as you take Sett’s cock into your mouth. You suck on his tip like it’s your favorite lollipop flavor, moaning from the taste of his pre, before taking him as far down as you can, hitting the back of your throat. His head falls back, a deep groan rumbling from his chest as you gag on him. His eyes squeeze shut, just enjoying the feeling of your warm and wet mouth bobbing along his fat cock. Suddenly he feels teeth nipping at his chest, looking down to see Kayn wanting in on the action, too.
Kayn trails sloppy, desperate kisses up Sett’s neck as you continue bobbing on his length at a steady pace, Kayn’s hand still holding your hair back. Your drool pools at the base of Sett’s cock, your soft moans sending little vibrations down his length. His own moans get breathier, louder as the coil in his belly tightens. He tugs at Kayn’s pink and purple hair, pulling him up for a desperate kiss as he groans, nibbling Kayn’s lower lip roughly. You can feel how much his dick is throbbing against your tongue now, his abs flexing against yours and your boyfriend’s fingers as he gets closer to his release.
Kayn smiles devilishly into the kiss and bites harshly at Sett’s lower lip, eliciting a deep groan from the redhead. His drawn-out groan turns into a whine as the bicolour-haired male pulls you away from the cock you were sucking so greedily on. You whimper a little at the loss but comply with his unspoken orders, standing at the edge of the bed, cunt leaking with your arousal. Drool covers your chin, your eyes glazed over, eagerness flooding through your veins as both men drink you in. Kayn is the first to move, standing next to you and licking the drool from your face before kissing you passionately.
Gods, you were so divine like this, so ready to please. It’s one of the many things he loves about you.
His hands settle on your hips, giving you a reassuring squeeze as he turns you around, your back now facing Sett. If only you could see the way Sett’s eyes lit up when your ass came into view, so plump and squeezable. The male bites his lip, wanting nothing more than to grope your soft skin and sink his teeth into the juncture where your neck meets your shoulder. He grows impossibly harder just thinking about it.
Kayn reaches down on either side of you, searching for Sett’s hands eagerly. “‘S what you’ve been wanting, yeah?” You can hear the teasing smirk in his breathy voice as he puts Sett’s hands right over the globes of your ass, the male sighing when your skin makes contact, squeezing roughly. Your boyfriend guides Sett’s hands to your hips before roughly pushing you back on the thick pad of muscles, a surprised sound escaping you as his arms wrap tightly around you, kissing your neck sloppily. His right hand travels up to grope your breast, squeezing the supple skin tenderly, lips and teeth still attacking your neck. His left travels down to the apex between your thighs, thick fingers sliding between your sopping folds, one teasing your entrance to collect more of your arousal. He teases you with slow circles to your throbbing clit, increasing the speed gradually as your sighs and moans become more frequent.
Kayn’s eyes are blown as he watches Sett’s fingers on your perfect pussy. He loves watching how you react to one of his closest friends stuffing you full with his thick fingers. Fingers he wants almost desperately around your throat. His throat. He reaches for his cock as you start to buck your hips against Sett’s hand, whining as he inserts one, two of his big fingers to scissor you open for him. You sound like such a perfect melody to both men’s ears, your whining increasing in pitch as the coil in your belly grows tighter and tighter. Your boyfriend drops to his knees, pumping his fist along his dribbling length faster, free hand holding your thigh as your legs begin to tremble as you approach your high.
His gaze briefly finds the other male’s with a slow lick of his lips, signaling his permission to finally fuck you.
Sett’s ears twitch and he groans into your neck as your walls flutter relentlessly around his fingers. Gods, you’re so tight. Your boyfriend helps pull the redhead’s cock out from under you, the heavy weight of him resting against your groin for a moment before your boyfriend gently grips him. Sett growls into your ear, hips bucking softly when the flat of Kayn’s tongue runs along the underside of his dick, teasing the sensitive veins that run along the length of him, tongue piercing fiddling around his frenum. Fuck, the whine you release when Sett’s hand travels to your neck, gripping tightly, as his other hand works your throbbing heat faster is almost enough to send him over the edge with you as your pussy tightens its grip around his fingers.
“That’s it, beautiful…” Kayn moans as his tongue pauses exploring Sett’s length to have a taste of your slick as you tremble in the muscular arms of the man beneath you. “Shit, you’re doing so good, baby… Such a good fucking girl…”
