Summary: One little fight leads you to poking your boyfriend’s buttons. You wanted his attention, but you didn’t expect him to take you somewhere private to show you just how much you already had it — and to teach you a lesson along the way.
The air in the car was thick with tension. You faced the window, avoiding all eye contact with Sebastian, your boyfriend, as he drove. Minutes went by and neither of you spoke, but you knew you were getting closer to your destination.
"Why do you have to argue every time we have plans like this?" He asked a few minutes later while pulling up to the party.
"I don't!" You replied, still staring out the glass.
You didn't do it on purpose. Something about parties like this always threw you off. You barely knew anyone, girls hovered Sebastian like bees on honey, and you hated crowds. Normally Sebastian was understanding, and it's not like tonight he wasn't, he just seemed... off.
He killed the engine right outside the small house. From the car you could see the strobe lights flickering through the curtain on the front window. Every flash made your heart beat faster.
You swallowed down what little pride you had left and grabbed your purse off the floor by your feet. Sebastian still came around to your side and opened the door for you. Through his annoyance, he still loved you of course — that would never change. Even the air outside was charged, waiting for a pin to drop and cause an explosion. You stepped into it and it was consuming. You just wanted to get back into the car and Sebastian to take you home.
His warm hand came down to grab your cold, shaky one to guide you inside. The closer you got to the front door, the more dread you felt. Sebastian stepped in front of you to open the door for you and ushered you inside. You were immediately hit with the smell of booze and cigarettes. The floor was vibrating along to the loud bass bumping from the speakers. So far, there was not a single face you recognized. You knew this would happen, it was exactly why you didn't want to come in the first place.
You both continued walking until you reached the living room — the main part of the party.
"I'm going to get us some drinks," Sebastian muttered, annoyance still heavy on his lips.
"Try not to get lost on the way back."
He rolled his eyes and stepped away towards the kitchen where all the drinks had been arranged. Your arms immediately crossed over your body to cover yourself. No corner of this room was left open, but you just wanted a place to hide until it was over. Suddenly you felt a pair of hands at your waist.
"Sebastian, quit it," you whispered angrily.
"Guess again darling," a raspy voice purred — you recognized it immediately.
"Garreth!" You exclaimed. "I didn't know you'd be here!" You pulled him into a big hug. His usual scent of warm apples and honey filled your senses.
Garreth was your old chemistry partner your first year of college. You spent plenty of late nights with him studying — or you studying and Garreth goofing off, thinking he knew better than the textbooks, but it had been forever since you had seen him last.
"You look as gorgeous as ever," he said. He was quite the charmer actually. You had a little bit of a crush on him before you had met Sebastian. He was covered in freckles, red hair the shade of fire, and green eyes that looked like ripe pears.
Then you felt him before you saw him. The air in the room became so tension-filled it was nearly as suffocating as the smoke.
"Hey baby," Sebastian said against your cheek as he kissed the soft skin. His arms snaked around you like they had always been there, but your fight was still heavy in your mind. You couldn't forgive like that just because he felt a little jealous. Then the idea planted itself in your head.
Easing yourself out of his arms wasn't easy and you knew everything after would be even harder, but you were stubborn. Your hands reached for the red-headed boy and wrapped around him in another hug.
"You remember Garreth don't you? Of course you do, he was only the best lab partner ever. He's the funniest person I've ever met," you said, looking right into Sebastian's eyes. They darkened at your words.
"Don't flatter me darling," Garreth replied, rubbing your arm. "You're a lucky man." He was looking at your boyfriend now who nearly had steam blowing out of his ears.
"Garreth was just asking me to dance. Weren't you Garreth?" You were laying it on thick.
Sebastian's jaw clenched and his grip around the small plastic cup tightened causing his knuckles to go white.
"If your guard dog doesn't mind," Garreth said while chuckling.
Sebastian didn't return a laugh, he didn't even crack a smile. "He does," he muttered lowly.
"He's only joking," you said, patting Garreth's chest. Your hands were still shaking and you hoped neither of them had noticed. You grabbed the cup out of Sebastian's other hand and downed it. The drink was fruity, but it still burned all the way down your throat and hit your stomach like a brick. Thankfully the shakiness was already wearing off as you grabbed onto Garreth again.
Somehow Sebastian's eyes got even darker now. They were staring holes into you and daggers into Garreth's chest. If looks could kill, Garreth would be on the floor before you — you might even be there too. "Come on Garreth," you whispered into your friend's ear, but turned your head enough that Sebastian could read your lips. Every drop of his name made your boyfriend flinch.
You dragged the red-head to the middle of the room where a makeshift dance-floor had been established. The crowd of people parted like the sea to allow the two of you to join in. Garreth grabbed you gently as the next song started, green strobe lights illuminating the room. Nerves started filling your stomach as the beat of the song started getting stronger. The floor beneath your feet pounded with every note, your heartbeat quickly catching up.
Garreth spun you around quickly with his soft hands — they were nothing like the warm, calloused hands Sebastian bore. The thought alone made you want to vomit. Guilt was eating you alive as your eyes found his from across the room. He was seething as he leaned his tall, lean body against a doorframe, drink still in hand. You had a goal to accomplish, so you swallowed down your sick and continued dancing.
The song continued on as you swayed with your friend. For a moment, you forgot how mad you were supposed to be. You were having fun like the two of you did those couple of years ago. You giggled as Garreth pulled a terrible shimmy move in front of you. You returned an even more awful dance move earning you a fit of laughter from him.
Your dress twirled as Garreth spun you again, only this time he pulled you in tighter than before. Your back was pressed against his chest as he was panting. Through the thin material of your outfit, you felt every breath he pulled in and out. You wanted to move, but you were frozen in place. Your eyes looked to the doorframe your boyfriend was previously standing in, only to find it empty of him. You furrowed your brows and started scanning the room when you felt another pair of hands on you.
"Songs over, mate," you heard his familiar voice call out. You could tell he tried to cover his anger, but he failed miserably.
"We just started dancing," Garreth replied, holding you tighter against him.
"I said songs over," Sebastian barked. Any regards he had for trying to sound polite were now out the window.
Garreth let go of you, but before you could muster up an apology, Sebastian was all but dragging you out of the room.
"You can't control me," you muttered as he pulled you down the long hallway. You tried pulling your hand out of his grasp, but his hold on you was too strong. It wasn't enough to hurt — Sebastian would never — but it was enough to let you know he was serious.
He made no effort to reply. His face stayed focused ahead of him as he guided you further. The next thing you knew, he was guiding you through a door.
"The bathroom?" You started to question, but before you could collect your bearings, Sebastian was on you.
He pressed you firmly against the counter as his lips crashed onto yours. One of his hands found your hair and roughly tangled his fingers through every lock. You were breathless by the time he pulled away. His lips found your neck almost instantly as he used the hand in your hair to coax your head back, giving him a better angle.
"S-Seb," you whispered, careful of not being too loud.
"This is what you wanted isn't it baby? My attention?"
More bricks formed in your stomach at his words. He read you like a book he had read a dozen times before as he sucked harder on the tender skin. He nibbled and licked away at the small bruise already forming below your ear. He trailed his lips a little lower to fresh skin, so he could paint a bruise there too. Every bit of skin his lips found were left mottled by his mouth. You knew what he was doing — he was marking what was his. Butterflies filled your stomach at the realization.
After he seemed satisfied with the mural he left behind on your neck, he brought his lips back to yours in an all-consuming kiss. He was still angry, you could feel it by the taste of the cinnamon whiskey on his tongue. He only drank it when he needed to feel something. Guilt filled your senses again, but his free hand trailed lower and lower until it found itself tangled between your thighs under your dress.
His hand found your cotton panties and pulled them hastily down your legs until they pooled on the tile floor by your feet. The guilt in your stomach was soon replaced by desire when his fingers found your soaking core.
"You're so wet already," he mumbled against your lips. His fingers quickly found your clit as they started slowly rubbing in circles.
"Sebastian," you moaned out lowly.
His fingers started moving faster, pushing down a little harder on your nub. Then his lips found yours again, swallowing every pant and moan that left your mouth. You were close to releasing already and Sebastian knew it too. Just as quickly as he started, he slowed. The tightening in your core stopped as you squirmed around him.
His lips moved slowly from yours and over to your ear where he pressed soft kisses against the shell. "You think after your performance, I was going to reward you that quickly? You have to earn it baby."
Another soft moan escaped from your lips at his words. The ache in your core was almost too much to bear, you could hardly stand it. You started subconsciously rubbing your thighs together, desperate to feel something — anything — again. Sebastian noticed your subtle movements and spread your legs further apart. He used a finger to tilt your chin up to face him, his lips brushed closely against yours.
"Good girls are patient," he whispered against you. "Show me you deserve to come." He peppered a few more kisses against your mouth.
His hands found your core again. You shuddered as he slowly dragged a finger through your folds, stopping at your clit. He started to massage again as you writhed beneath him. He was going painfully slow, still eager to tease you. He watched you intently as your head leaned back against the medicine cabinet behind you.
Your orgasm started to build up in your stomach again. Sebastian looked you in the eyes. "Don't come yet," he said. You wanted to be good for him, you knew you had to be to get what it was you wanted. You fought against the release you so badly wanted. You squirmed against his hand. "You're so pretty when you struggle for me." And then he stopped. It felt like being slammed into a wall. Then he kissed you again, covering up all of your whines.
He repeated the process again — circling his fingers around yours clit until you felt like maybe this time he would let you finish, only to be met with his fingers pulling away from you again. You were so desperate to finish, you would've done anything — which is exactly where he wanted you. Again, you found yourself with his fingers massaging your nub. You were breathless and struggling against him.
"F-fuck Sebastian," you moaned out, louder than intended.
His free hand came up and covered your mouth. "Shh, be quiet for me baby," he whispered. You moaned against his hand in agreement. He kept his hand there as he gained momentum. "You're so needy aren't you?" You nodded your head against his hand.
Suddenly you both heard a knock at the door and Sebastian got a devious look in his eyes, while yours widened. He didn't stop his movements either. "Tell them someone is in here," he whispered into your ear. Your eyes got even wider at his request. Your head shook against his hand. "You wanna come don't you?" He asked. You did — so badly. "Then tell them it's occupied."
You heard another knock on the door, this one a little harder than the first time, but Sebastian hadn't moved his hand away from your mouth yet. He kissed your neck hurriedly and trailed them down your exposed chest. And then you felt him plunge two fingers inside of you, his thumb replacing his middle that was circling your clit. The dual sensation was almost enough to make you orgasm on the spot.
"Is someone in there?" The voice outside the door finally called out.
Sebastian then moved his hand away from your lips.
"Fuck," you breathed out while biting your lip. "S-someone is i-in h-here." It was a struggle to get every word out, but Sebastian was smirking, you could feel the curl of his lips against your chest.
"Good girl," he breathed out against your skin. The coiling in your stomach started winding up again. "You're so close aren't you."
You were a mess sitting on the counter beneath him. You nodded your head gently and closed your eyes. "Y-yes," you whimpered.
"Do you think you deserve to come?"
This time you shook your head, but didn't have it in you to say the word and you were met with a low chuckle.
"But do you want to come?" He asked.
You did — God you wanted to. "Yes," you whispered.
"Beg for it," he said and slowed his movements.
"Please," you whispered, but it wasn't enough to get his movements started back up.
Sebastian must've been satisfied with your response as his motions started back up again. He was fingering you with two fingers, circling your clit with his thumb, and now he was sucking gently on the already formed bruises on your neck. The feeling was almost too much and you nearly moaned his name too loudly.
Your orgasm hit you like a train — the release finally crashing into you over and over again. His mouth found yours again, kissing you through your climax. When you finally settled, you were still aching for more.
"I need you," you said against his lips.
"Such a needy little thing aren't you?" He teased as he unzipped his dark jeans.
You stayed seated against the bathroom counter as he lined himself up to your entrance. Slowly, he pushed himself into you, stretching you out bit by bit in a familiar way.
"S-Sebastian," you whimpered.
"Fuck you feel so good," he replied. When he was all of the way in, he stopped for a moment to let you adjust before pulling out. This time around, he pushed in harder, sending your ass scooting back a little further onto the counter top, but with a swift pull of your thighs, he had you back exactly where he wanted you.
Your hands found their way into his soft, brown locks as he pumped in and out of you. Your lips traced lightly against his as you breathed in each other's moans.
"Say you're mine," he breathed into your opened mouth.
Electricity shot through your chest all the way down into your core. "I'm yours," you moaned out. "I'm all yours, Sebastian."
His damp forehead pressed delicately against yours. His thrusts were started to become more frantic and you felt yourself barreling towards a second orgasm.
"Say it again baby, please," he pleaded.
You pulled his lips towards yours in a crashing kiss. "I'm all yours. Every bit of me."
You felt your orgasm take over at the same time Sebastian released inside of you. You rode out your climaxes together, leaving you both heaving messes. When the final waves crashed over you both, he kissed you again.
He helped clean you up and readjust your dress, but you gasped when you looked into the mirror and saw the deep plum markings across your neck. "Sebastian Sallow," you whisper-yelled.
"That's what you get for fawning over Garreth Weasley in front of me," he teased. "And if the bloke calls you darling one more time, I might have to crack his jaw."
"I wasn't fawning," you replied. "I was only trying to get you to sweat a little."
Sebastian swatted your ass and pulled you in for one final kiss before you had to brave the party with a fresh new painting across your throat. You slowly opened the door to make sure no one was waiting out in the hall. When you saw the coast was clear, you grabbed your boyfriend's hand and dragged him back to the party.
"Where have you two been?" You heard Garreth's voice call out as you walked back into the crowded living room.
"We were just getting some... fresh air. Lots of fresh air," you lied, hoping the dark lights covered your bruises, but by the surprised look in his eyes, you knew he saw right through you. He coughed, made up a sorry excuse, and left the two of you alone.
"Dance with me darling?" Sebastian mocked and the two of you found the middle of the room, where you continued dancing until the night ended.
