The Stilinski siblings had a pretty well... notorious reputation at Beacon Hills High. The oldest, Mitch Stilinski, was in college now, but his younger brothers, Thomas and the twins, Stuart and Stiles, still gave all the teachers unfortunate enough to have them in their classes a hard time.
You were familiar with them, especially Stiles, with him being your boyfriend and all. Whenever you were over at his house, it felt like you were being watched constantly. His twin, Stuart, would spread out on the couch, scrolling mindlessly through his phone while sneaking glances at you. Mitch had the eyes of a predator. It was obvious when he was staring at you. Thomas’ gaze was more gentle, but definitely still noticeable.
This time, you were supposed to go to the Stilinski house for a history project with Stiles. The sheriff wasn’t home, but his sons definitely were. You knocked on the door, expecting Stiles to greet you, but it was Thomas who answered.
"Hi?" He murmured, not making eye contact with you.
You stared at him blankly. "Hey."
The silence was palpable. There was some shuffling behind him and a voice called out 'who is it?'. Mitch peered over Thomas' shoulder. "Let her in, idiot," he grumbled. Thomas sighed and stepped aside, running his fingers through his brown hair. His brother gazed at you through thick eyelashes. "Stiles is in his room," he said quietly.
You muttered a quick thanks, pushing your way past both of the brothers and hanging up your coat on the rack. Thomas nearly choked when he saw the skirt you were wearing underneath. Mitch had already walked away at that point. Making your way up the stairs, you hummed under your breath, clutching your backpack to your side as you made your way to Stiles' bedroom. After knocking a few times, there was no answer, so you slowly opened the door.
Instead of finding Stiles, you were met with the bare back of his twin, Stuart. The boy with glasses scowled and shouted at you to close the door. With a red face, you shut the door, your heart thudding against your chest. It seems that you had forgotten the twins had shared a bedroom, and Stiles was in fact not in there.
The door down the hall opened and the familiar face of your boyfriend peeked through. His eyes lit up when he saw you. "Y/N! Why didn't you tell me you were here already?" He chuckled. You two approached each other, Stiles wrapping his arms around you in a tight embrace.
"I wanted to surprise you," You whispered in his ear. You could feel his heartbeat start to pick up at your words.
"Well, I'm surprised all right."
His hands slowly trailed down to the short skirt you wore, specifically picked out just for him. Stiles hummed in approval when he felt that you weren't wearing shorts underneath. You threw your arms around his neck, lacing your fingers through his hair that had grown out through the summer and fall. It was a thrilling feeling, touching each other in the hallway when any of his brothers could see, but who's to say you didn't want that?
Stiles' fingers dug into your thighs, his eyes fluttering shut as he let out a shaky breath. "I wish we had somewhere more private to be," he rasped. Looking up at him, you brought your hand up to brush at the moles littering his pale cheeks.
"It's okay. We have that project to finish anyway," you replied. As the words left your mouth, Stiles lifted up the back of your skirt in one bold movement, palms cupping your ass through your lacy panties.
"How can you expect me to wait? This has got to be some sick joke," he groaned. A shiver shot down your spine and you slapped his shoulder.
"Why would you do that?" You hissed in embarrassment, pulling down your skirt. Unbeknownst to the two of you, Stiles' counterpart, Stuart, was watching the whole scene unfold. He cleared his throat, crossing his arms.
"No shame? Just... rubbing up on each other in the hall? Right here, where everyone can literally see?" Stuart scoffed.
Stiles grumbled under his breath, muttering a curse to his twin. "We weren't rubbing up on each other, actually," he corrected. You stared at the Stuart, mouth agape in shock. He stared back at you, irritated with his twin's reckless behavior in the hall. But what you three were oblivious to was Thomas and Mitch listening from the stairs.
Your boyfriend sighed heavily, pinching his nose bridge. "What is your problem? Every time I bring her over you just act like the biggest dickhead in the world! Matter of fact, why do all of you act like th-"
"How can you expect me to act normal when she looks likes that?!"
Stiles' eyes widened at his twin's audacity. His heart skipped a beat when his older brothers emerged from the stairs, standing behind Stuart. "What the fuck is going on?" Stiles muttered. You stood behind Stiles, swallowing down a lump in your throat as his siblings stared at you like wolves preying upon a lamb. It was silent for a very long time, the only sounds breaking the silence being the buzzing lightbulb hung in the middle of the hall and everyone's heavy breathing.
Stuart was about to leave, his phone in his hand, but Stiles' voice stopped him.
"So... all of you... have a thing for my girlfriend?" He queried. There was a hint of amusement in his tone.
Mitched huffed, fist clenching and unclenching, making his veins bulge. "It's pretty fucking hard to control ourselves when she just walks around wearing that tight little skirt," he growled. Thomas was chewing at his bottom lip, brows knitted together as if he were concentrating. Sweat beaded around your forehead. Was this really happening? It was something straight out of a dirty fantasy.
"Okay, man- I didn't ask for-"
"One night, Stiles. Share her with us for one damn night, please?" Thomas practically begged, cutting his brother off. Stuart and Mitch were waiting for him to answer. Stiles stared at them all in disbelief.
"No! What the hell? Why would I-"
"I want to," You whispered.
"Uhm, no way, Y/N. You're my girlfriend, I'm not sharing you with these behemoths-"
"Shut up. She wants it too," Thomas croaked. All four brothers were looking at you in shock.
Everything after that was a huge blur. What you could make out was arguing and hands guiding you down the stairs. Stiles continued to protest, but never really tried to stop what was happening. Mitch sat you down on the couch, leaving you staring up at all of them. They were all so... alike. Each one of them had a mole-littered face and honey-colored eyes. All of their heads sprouted the same brown hair, varying in length. And though Mitch had stubble lining his jaw, he still looked as young and sexy his brothers.
Stuart clearly wasn't getting enough stimulation from just standing around staring at you, so he started using his phone like usual. Thomas snatched it away, placing it on the coffee table. Before he could protest, Mitch spoke.
"You sure you want this? All of us for tonight? At once?" He asked, waiting for confirmation before continuing any further.
Stiles stood watching from the side, a light blush dusting his cheeks with a bitter expression on his face.
"Then take your clothes off and be a good girl," Mitch demanded.
The weight of his command slapped you in the face and your hands shakily came up to pull off your top. As soon as your bra-covered tits hit the air, Thomas exhaled heavily. Stuart reached for his phone, none of his brothers stopping him from snapping a picture. The flash is what brought you back to reality, fingers finding the zipper at the back of your skirt and pulling it down.
Tossing your top and skirt to the side, you spread your legs to reveal a wet patch that had formed in your panties. Mitch let out a low growl, crawling onto the couch beside you and reaching for your underwear. Thomas and Stuart immediately followed, Stuart crouching down in front of your legs and Thomas sitting on the opposing side Mitch was. Stiles peeled his shirt off, tossing it on the coffee table and settling down next to Thomas.
Mitch tugged your panties down in a single swoop and all the boys groaned at the sight of your wet pussy. You closed your legs on instinct, but Mitch wouldn't let you. He wedged his palm between your thighs and grabbed one, Thomas repeating the same action on the other side. Stuart stared at your cunt head-on, his hands resting on your knees. Your boyfriend already had his pants off, palming at his dick through his boxers while watching his brothers handle you.
As Stuart brought his face closer and closer to your pussy, his glasses started to fog up from the warmth of his breath combined with your cunt. The tip of his tongue tickled your clit, making you jolt and try to clamp your legs around his head. Mitch and Thomas pried you open, Mitch grabbing your face with his free hand.
"Keep your legs open," he spat.
You nodded, whimpering. Stuart was teasing, nibbling that bundle of nerves and pressing kisses on the insides of your thighs. When his tongue flattened against your core, a loud moan escaped you. Thomas muffled your sweet noises by pressing his lips against yours, Stiles grunting in jealousy. You kept your eyes on your boyfriend and his cock, watching as he stroked himself to the sight of his twin eating you out. Soft gasps and whimpered continued to leave you, but for Stuart, it wasn't enough.
He shoved two fingers into your cunt, making you yelp at the sudden intrusion. The pads of his fingers rubbed against your gummy walls, making you writhe in Thomas and Mitch's grasp. Stuart pistoned his fingers in and out of your pussy, eliciting gasps of pleasure every time his fingers went deep enough. His other hand went to your clit, rolling the little nub between his fingers as your voice started to raise. The brothers holding you open both had very prominent bulges in their pants and your hands scrambled to hold onto something.
Mitch let out a deep groan as your left hand grabbed his clothed dick, Thomas whimpering when your right squeezed his balls. Stuart's fingers had your eyes rolling back and toes curling, whispers of his name escaping your lips. He pulled his fingers out and motioned for his twin to come. Stiles shifted over to his brother, reluctantly wrapping his lips around his fingers and sucking your arousal off of them. That was enough to send you off the edge. With his thumb still stimulating your clit, you were just about to cum, but Stuart pulled away cruelly.
A strangled moan left you, sounding like a growl and cry. You stared at him in disbelief, watching him wipe Stiles' saliva on his pants. Mitch had an amused grin on his face, his fingers giving your thigh a firm squeeze. Stuart was smirking at you, adjusting his glasses.
"What the fuck! I was just about to-"
"Oh, I know. That's why I stopped you," He interrupted.
You let out a groan in frustration but quickly snapped up at the sound of pants being unzipped. Mitch, Thomas, and Stuart had discarded their sweats. Stiles unclasped your bra from behind, throwing it to the side and grabbing your bare tits. His warm breath fanned your neck as he muttered incoherent nonsense in your ear about how jealous he was.
The brothers shifted around the couch, trying to determine how this would go. Stiles held you close to him while his siblings conversed with each other. They all started to nod and turned towards you two.
“She take it in the ass before?” Mitch asked bluntly.
“No. At least not with me,” Stiles replied, playing with your breasts.
“Uh- I’ve never done that befor-“
“Great. Then it’ll be your first time,” Mitch smiled.
Stuart took off his shirt and approached you. “We’ve decided we all want to have a go at you simultaneously. I don’t care what Stiles thinks, so we’re gonna have two pretty dicks in your mouth, one in your tight little ass, and someone lucky is gonna get that sweet cunt,” he grinned, giving your pussy a playful slap. Stiles clenched his jaw, stifling a moan when your ass nudged his cock as your body jolted from the slap.
Thomas took you away from Stiles, strong arms guiding you down to the floor. Your knees dug into the carpet as you looked up at the four men.
“Sorry. No room on the couch,” Thomas said sheepishly, his cock thick with arousal.
“I feel like Stiles should only be able to get off in her mouth-“ Stuart started.
“Why? That’s not fa-“ Stiles argued.
“Yes it is! You can fuck her pussy or ass any time that you want! Just be glad we aren’t making you watch,” his twin scoffed.
“Alright both of you shut up. I call dibs on that cunt,” Mitch said.
“I’ll take the back then,” Thomas sighed, looking a bit disappointed.
Stuart frowned. “I don’t want to be stuck with Stiles. Promise I get the pussy after?” He asked Mitch. The older man nodded. Stiles was itching to just grab you and drag you away from his crude brothers.
A couple minutes were wasted trying to find a position that worked, but the floor was far too uncomfortable. Stiles ended up carrying you up the stairs and to Mitch’s bedroom, gently setting you down on his brother’s large bed. The rest of the boys followed, making comments on how you looked sprawled out on the bed.
Thomas crawled onto the mattress, reaching for the nightstand and pulling out a bottle of lube. You didn’t know how he knew where Mitch kept his… things… but questions would only make things awkward. Thomas pulled you towards him, pouring a generous amount of the cold gel onto his fingers. He spread your asscheeks, rubbing the cold substance around your puckered up hole. It made you shiver, but when he slipped in a finger you sucked it right in.
“Oh… wow…” he gasped, knuckle-deep. Thomas was slowly stretching you out, prepping you for his dick. He added another finger, now having two fingers scissoring inside your asshole. You squirmed, squeezing your eyes shut at the burn. Mitch, Stuart, and Stiles all watched hungrily, stroking their cocks in sync with Thomas’ fingers.
You couldn’t tell if he decided that you were ready or he just lost interest in fingering your ass, but Thomas laid back onto the sheets, stroking his dick with lube. He gestured for you to follow, and you did. Thomas guided you so that you were lying flat against him, back pressed to his chest. The tip of his dick pressed against your asshole, wet and ready to penetrate your tight hole.
“Ready…?” He whispered in your ear, fingers soothingly stroking your hips. You nodded, gasping when he slowly pushed in.
It burned like hell, making your entire face scrunch up in pain. Stiles had a grim expression on his face, but Mitch and Stuart were loving it. Thomas was grunting, eyes rolling back at how tight you were around him. He gripped your hips tightly and shoved all the way in. A scream left your mouth, followed by an unexpected moan.
Mitch chuckled and smirked, pushing himself between Thomas’ legs hanging off the bed and your cute cunt presented to him.
“Hold her legs open,” he told Thomas. Thomas hooked his arms around the back of your knees, spreading you wide for Mitch.
Mitch spit on your pussy, rubbing in his saliva using the head of his cock. His balls brushed against Thomas’ as he slowly pushed into your cunt. You whined, hands clutching at the sheets. The thin wall separating their cocks only did so much. As Mitch began to find his pace while Thomas bounced you up and down, their tips rubbed together just right.
Stiles and Stuart each got on one side of you, grabbing your hands and making you jerk the off. You were moaning and nearly screaming, too focused on the feeling of two fat dicks penetrating your pussy and ass to properly jerk the twins off. Stuart got frustrated and brought your mouth to his dick, forcing it down your throat. You choked and gagged, tears brimming your waterline as your boyfriend’s twin face-fucked you.
It felt degrading, you felt like a whore but it felt so damn good. Stiles aggressively jerked himself off, watching as his identical twin and older brothers ruthlessly fucked his girlfriend. Mitch’s dick was bullying your poor pussy’s walls while Thomas was practically rearranging your guts. Your throat was accommodating to Stuart’s size and you didn’t even notice Stiles replacing his hand with yours.
“Oh fuck- I’m about to cum…” Thomas groaned, pulling your legs closer to your chest. The dick in your mouth was muffling every little sound that tried to come out. Mitch was growling, snapping his hips against yours trying to chase his orgasm.
“This ngh- fucking slut,” he grunted, “takes dick so well. Like she was made to be fucked by four dudes,” Mitch laughed, pinching your clit between his fingers. The room was filled with heavy panting, wet slapping sounds, and gagging. Stuart eventually let Stiles have a turn at face-fucking you. Your boyfriend wasn’t usually this rough, but Stiles didn’t care anymore. He held you all the way to the base of his cock for multiple seconds, making your vision go spotty.
Thomas was practically moaning as loud as you would be if there wasn’t fat dick in your mouth. His arms were still holding you wide open and his balls were slapping against your ass with every thrust. He bit his lip and groaned loudly, filling your ass with hot seed. At the sight, Stiles managed to cum straight down your throat, his entire body shuddering with pleasure.
When your boyfriend pulled out, exhausted from his pleasureful orgasm, his brothers all pulled out at once, making you whine at the loss of contact.
“Oh shut up. You’re about to get railed into oblivion,” Mitch growled. Thomas’ cum dribbled down your thighs, wetting the sheets. Mitch got behind you and quickly thrusted back in, your hands and knees supporting your weight as he tugged your head back by your hair. A loud cry left your throat as he slapped your ass roughly.
Stuart got in front of you and pressed his hard dick to your lips, slapping you on the cheek. His glasses were knocked askew on his face, but he didn’t seem to give a shit. “Suck it, cmon baby.”
You could still taste his twin’s cum in your mouth. Your lips parted around his head, suckling the tip like a lollipop. Mitch was pounding into you from behind, ruining your pussy. Thomas and Stiles watched from the edge of the bed, slowly jerking themselves off after have cumming too soon.
Stuart’s fist joined Mitch’s, gripping your hair and thrusting his hips further into your mouth. Mitch’s thrusts were slowing down but getting deeper, his free hand slapping your cheeks raw.
“I’m cumming in this pussy. Breeding this slut like a bitch- fuck! Knocking her up and nobody would know Stiles isn’t the father,” he rambled, giving a final thrust as his dick exploded with warm cum. Stiles let out a jealous growl, hand freezing its movements on his dick.
You let out a muffled scream around Stuart’s cock, feeling Mitch’s baby-batter fill your stretched out cunt. Your boyfriend’s twin did the same thing he did, holding you to the base of his cock before shooting a fat load down your throat. He moaned loudly, fingers tangling in your hair. Mitch pulled out, his dick leaving a sticky trail of cum connected to your fucked-out pussy.
Stuart let out a heavy sigh as he parted from your mouth, wiping sweat from his forehead as he adjusted his glasses. You coughed up his nut, licking your lips and humming in content. “Round 2?” You smiled.
“Fuck yes,” they all said in unison.
