A Torrid Arrangement - Sebastian Sallow x Female! Reader

Summary: You and Sebastian have had a 'friends-with-benefits' dynamic going on for close to a year now, and the more time passes, the harder it is for him to hide his true feelings for you. It's an unbearable kind of torment, but he forces himself to grin and bear it anyway to preserve the integrity of his... situation-ship with you. That is, until the metaphorical floodgates finally open up.

Alternatively summarized as gratuitous FWB smut with lots of playful banter sprinkled in

This came from the depths of my fever-induced brain so if its all over the place, I apologize. But YAY MORE SMUT !!

Word Count: 8.6k

Warnings: 18+, aged up characters, explicit sexual content, lots of hickies

Full fic can be found here on Ao3 with more informative tags, as per usual :))

Sebastian knew it was going to be one of those days before he was even fully conscious.

He jolted awake from an extremely graphic wet dream at the ass crack of dawn, hard and sweaty and tangled in the sheets, already reaching beside himself for the body that had just been pressed against his own. The dream had been so real– so incredibly vivid– that he swore he could still taste the familiar, salty skin on the tip of his tongue. He’d been so fucking close too; buried deep between soft thighs, clinging tight with every fiber of his being when reality had come and butt its ugly, unwelcome head in.

With a ragged, disappointed groan, Sebastian let his head fall back against his pillow and dragged his hands down his flushed face, graciously allowing himself a few minutes to sort himself out.

This was far from the first wet dream he’d had about you, and he was certain it wouldn’t be the last. Hell– you gave Sebastian’s thirsty subconscious plenty of material to work with every time you came around to ‘relieve stress’. Being long-standing fuck buddies with you granted him that lucious priviledge. Sebastian knew damn well how good you felt holding onto him, what you sounded like when you were about to come, what your heated, sweat-slick skin tasted like.

He also knew how fucking cute you could be— especially when you were sprawled across his bed in his dorm with a textbook open beneath you to sneakily segue from studying together to fooling around. He knew how badly he wanted to spread you out across his sheets and make you moan for hours– to worship your perfect body slowly and sweetly with his hands and his mouth.

It was barely past dawn and Sebastian already knew he was going to be tracking you down at some point today to act on his urges. As always, he would be hiding his monstrous crush under a thick layer of casual booty call.

—

Whenever Sebastian woke up like this– nerves stretched paper thin over a desperate craving for intimacy– dueling was one of the few things that helped him clear his head and get his shit together. He wasn’t exactly a morning person, and he was even less of a people person at such a ripe, early hour, but he’d still left the confines of his dorm to make the trek to the Crossed Wands courtyard.

There were no students in this area of the castle at this time, which just meant he would be making do with the practice dummies for a few hours until his blood cooled within his veins. Spell after spell fired from his wand and struck hard and true against the wooden figurines that lined the walls, the sound echoing off the Clock Tower walls and drowning out his incessant, horny thoughts.

Thoughts that revolved too much around how nice your thighs would look with dark imprints of his teeth all over them.

Biting the inside of his cheek, Sebastian unleashed a particularly aggressive Confringo charm in a bid to expel his sinful train of thought. The dummy erupted in an explosion of wooden bits and flaming embers, and as it collapsed to the stone floor in a mangled heap, the brunet realized that there was in fact one other person on school grounds awake– and they just so happened to be walking right towards him.

He could practically hear fate howling with laughter at his expense when he dimly registered that not only did he know this lone survivor, it was against all probability none other than you, because why the fuck not.

You were stomping through the outer courtyard with a few textbooks clutched tight in your white-knuckled grip, looking equal parts distracted and deliciously disheveled from a distance. Your mind had to be as scattered as his was, because you clearly didn’t notice Sebastian or the on fire training dummy as you strode through the open clock tower gate. He did his best to play it cool when you finally made eye contact with him, trying exceptionally hard to not look like he’d just jacked off to the way dream-you squirmed under him not twenty minutes prior.

“Hey, you,” Sebastian called out smoothly when your hurried pace slowed down at the sight of him. You shook your head as though to clear it, squinting at him harder as you evenly stalked up to him, and your frown became more and more apparent the closer you got. Everything about your demeanor screamed ‘wild Graphorn, do not approach’, but Sebastian had never been great at following directions.

You raked one of your hands through your wild hair as you finally came to stop a few feet away, panting slightly as you stared up at him as though you weren’t entirely sure he was real. “Sebastian?”

The man in question cocked a brow at you, giving you a quick once over. Your hair was definitely mussed more than usual, a few stray strands falling over your forehead while others stuck up on one side– as if you’d been combing your fingers through it all night. There was no missing the mildly insane glint in your bloodshot eyes, and you were slightly paler than normal. Sebastian was also pretty sure you’d been wearing the same blouse yesterday, if the tiny stain on the collar was any indication.

If you didn’t look so damned grumpy, Sebastian would swear he’d just caught you in the middle of a walk of shame. The mere idea sent a sharp pang of jealousy straight through his core, and he had to bite his tongue to stifle the snide comment that threatened to fall from his lips. He failed, opting to instead poke the metaphorical bruise and deal with the throbbing ache doing so would bring him.

“Someone didn’t go to her dorm last night,” he snickered, aiming a crooked grin down at you. “Congrats on getting lucky.”

Normally he would expect you to just roll your eyes and punch him in the shoulder before ribbing him back. But as Sebastian watched your eyes widen at the same time your face flushed several different shades of red, he couldn’t help but wonder if poking the metaphorical Graphorn before the sun was even fully up was a good idea.

“I was not getting lucky,” you hissed at him, one eye twitching. Sebastian raised his hands in mock surrender before sticking his wand back in his pocket, awkwardly shifting on his feet for a moment as you huffed out an agitated sigh. “I’ve been getting fucked for the last twelve hours by Professor Sharp’s assignment– fifteen pages on the origin and uses of Wiggenweld. I’m not even sure if most of what I’ve written comes off as real English, so don’t fucking chuckle at me about getting lucky, you ass.”

Sebastian just stared at you silently, watching you fume. He’d pulled plenty of all-nighters with you before, so he knew full well that after a certain amount of sleep deprivation and stress, you had a tendency to lose your shit in addition to your filter. “Ah,” he mumbled as he rubbed the back of his neck sheepishly, only hesitating for a second.

After all, he just so happened to know exactly how you liked to relieve your stress.

He licked his lips quickly before he said, “You, uh… kinda look like you could stand to get lucky, huh?”

Your nostrils flared slightly as you squinted up at him for a long minute instead of responding. It might have looked like a murderous face to anyone else, but Sebastian knew better, and he could practically hear the gears in your head clanking together as you weighed the offer.

“…I mean, if you’re not doing anything else,” you finally muttered, your tense shoulders dropping a smidge.

He gestured loosely to the demolished pile of wood on the ground. “I’m not anymore,” came his fluid reply, and before you could take note of the smoking remnants of the training dummy, Sebastian’s hand was grasping yours tight as he tugged you along behind him. You blearily blinked the fatigue from your eyes as you fell into step beside him, and the brunet tried his very best not to let on how extremely pleased he was.

—

Halfway to Sebastian’s dorm, you’d interrupted his hurried pace and directed him to the Room of Requirement in an attempt to avoid any awkward run-ins with his roommates. The absolute last thing you wanted to deal with on top of your Potion’s related irritation was prying eyes, and you already knew the Slytherin dorms would be chock full of those.

Upon entering the more private space atop the Astronomy Tower, you threw aside your textbooks on the lone side table next to the double doors and spun around to yank Sebastian into a frantic, needy kiss. Your nails dug into his firm shoulders as you swiftly pulled him down to your level, and he allowed you to grind your hips against his steadily growing erection as his own fingers dug into the small of your back.

“H-Hey, hold on,” Sebastian wheezed out when you pulled away to tug at his belt, and his hands dropped to your waist to hold you at arms length so he could look you over again. As the two of you had trekked up to the Room, you’d begun to look more and more exhausted— too out of it to even gripe about the endless staircase that never failed to draw complaints from you. “Are you sure you’re up for this right now? You look like death.”

You snorted and rolled your tired eyes, pursing your lips in blatant disapproval. “Nagging, Sebastian? Really? I thought we were past this.”

“I’m not nagging,” he grumbled. “I’m just saying, you kinda look like you need a nap more than you need a quick fuck.”

Tutting disdainfully, your hands fell away from his belt as you crossed your arms over your chest. “I was just starting to loosen up. See if I ever relax around your ass again,” you retorted drily, tilting your head back to blink up at the ceiling. “The assignment is due before lunch today. If I sleep now, I’m not waking up until tomorrow. I can’t sleep yet.”

Sebastian tilted his head with a thoughtful frown, mirroring your stance by crossing his arms over his own chest. “What if I wake you up?”

You shook your head dutifully, although you were sorely tempted by the idea. “Trust me, I can feel the impending coma. I can’t risk it.”

“Want me to turn your paper in for you?”

Another mournful shake of your head. “You know Sharp, he’s as stern as they come. I’m positive he wouldn’t take it from you– and I’m sure he’d give you detention for trying. It’s fine, I just need to tough it out for a few more hours. Think you can help with that?”

“Shit, yeah,” he relented, fighting the urge to bury his face in your messy head of hair. Instead he opted for uncrossing his arms to run his hands up your shoulders to gently squeeze at the tense muscles there, and you sighed at the delightful shiver that danced up your spine from the action. “I’m really not trying to kill you, though. Are you sure you’re good for this?”

You snorted again, shaking your head slightly, and the tension in your upper body began seeping away under Sebastian’s warm palms. “Are you always this sweet to your fuck buddies?” The brunet could feel himself flushing at the statement, but before he could respond, you were muttering, “It’s really weird coming from you.”

“Hey–”

“Just shut up and fuck me already,” you barked over Sebastian’s protest, pulling away from him to head further into the massive space towards the modest bedroom in the corner. The adjacent room had never disappeared after your first hook-up here with your longtime companion, and its constant existence since then had served as an odd reminder of your arrangement with the man.

If you weren’t so stiff and weird from exhaustion, Sebastian could honestly convince himself that you were embarrassed or something. For now, though, he simply chalked your jaded nature up to your lack of a filter and stalked after you– totally not obsessing over the fact that you’d just called him sweet.

You’d been undoing the buttons on your shirt as you walked, and as soon as you made it inside the bedroom, you stripped the material off completely and discarded it in the corner of the room. Your skirt quickly followed, and all the while Sebastian was forcing himself not to think about how nice dream-you’s skin had looked tangled in his dream-sheets.

Sebastian stood in the doorway as he began unbuttoning his own shirt, shucking the attire off of his shoulders before moving down to his belt. The metal clink of the buckle was enough to draw your attention, and you fell back onto the mattress and scooted up towards the pillows without taking your eyes off him. The eager look in your fatigued eyes was enough to spur Sebastian onward quicker, and before long he was dressed in only his briefs as he prowled towards the bed with a predatory glint in his eyes.

The way you were sprawled atop the sheets with your arms resting above your head was a sight Sebastian vowed to commit to memory for as long as he lived. You were clearly giving him free reign over your body, and his mouth ran dry at the realization that you were wholly handing control over to him. He swallowed thickly and moved to straddle your hips, leaning over you on his forearms so he could better slot your lips together, and after a few tentative pecks, his boldness started to grow. You sighed and tilted your chin into Sebastian’s kisses, parting your lips invitingly as you melted into the cool, satin sheets beneath you.

With as tired and as boneless as you were, it seemed like you might actually be patient for once, and the thought had Sebastian’s heart fluttering excitedly. More often than not, he was so susceptible to your impatience and intensity that he always found himself getting swept up in your urgency when the two of you did this. Not that he didn’t love it; the dire, rough pace he’d always settle into with you, all gasping moans and tightly-gripped hands and frantic, needy thrusts– he absolutely loved it. It kept him hooked and craving more, even when you were both panting and sated. This, though…

Having you give up the lead and just relax for him was like a literal wet dream come to life.

Tangling your tongues with a low moan, Sebastian leaned into you slightly, his hands shifting to rub slowly up your sides until his deft fingers slipped under your arched back to unhook your bra. It fell away like nothing, and you moaned against his lips when the pads of his thumbs came to graze over your pert nipples. Your sleep-deprived loopiness had to be contagious, because Sebastian pulled away from your lips to mouth hotly against your ear, “I dreamt about you last night.”

He didn’t get the chance to feel weird about admitting it. You chuckled warmly, your kiss-swollen lips curving into a crooked, amused smile. “Oh yeah?”

“Yeah,” he murmured, pausing to suck gently at your earlobe while his thumbs idly traced the outline of your ribs. He brushed his lips down the angle of your jaw, exhaling shakily when you leaned your head aside to freely offer him the wonderfully sensitive expanse of your neck. Sebastian lightly dragged his teeth down the soft, heated skin, then flicked his tongue over the faded imprint of the last hickey he’d left there. It was barely noticeable now.

You shivered at the feeling, your fingers twisting in the sheets above your head before you sighed contentedly. “Was I pulling my hair out about Potions?”

“Fuck no.” He nipped at the faint bruise before pressing a hot, open-mouthed kiss to your pulse, sucking just enough to briefly tease you. “I had you under me like this,” he continued softly, pitching his voice low and nuzzling into your ear again, purposely aiming to press your buttons and work you into a needy frenzy. He felt your breath hitch more than he heard it, and as a sly grin broke out across his face, Sebastian slipped his fingers up your chest to pinch at your nipples once again. “I was fucking you nice and slow, making you feel so good…”

Moaning softly, you arched up into Sebastian’s hands, worrying your bottom lip between your teeth as he teased and flicked the sensitive nubs into stiff peaks. Your hips inadvertently rocked up against his as you desperately sought friction in the area you wanted it most. “Sounds like you’ve already got a game plan, huh?”

He sat back on his heels to look down at you as he shrugged. “If you’re up to it,”

“Just don’t let me fall asleep,” you mused, your hooded eyes trailing down Sebastian’s tanned, freckled chest to his dark briefs, halting when you caught sight of his cock straining against the cotton material. The sight had you licking your lips and fidgeting slightly before you blinked back up at him. “This paper is worth a quarter of my grade.”

“I won’t. Merlin– you worry too much.” Sitting upright with an amused shake of his head, Sebastian rolled off of you to sidle down the mattress so he was kneeled comfortably between your outstretched legs. Your hands fell to your thin underwear, ready to peel them away to get a move on with things, but Sebastian swatted away your appendages quickly. With a half-hearted scowl, you relinquished control, allowing your arms to rest above your head again as you once more bared yourself to the larger man.

Sebastian groaned softly at the sight, continuing where you’d left off by slipping his fingers under the waistband of your undergarments before tugging the damp fabric away from your aching center. You lifted your knees to assist him, and in one swift motion he had discarded the soiled attire over his shoulder, taking care to drag his eyes down the supple curve of your waist before settling on your glistening folds.

“Damn, darling,” he moaned earnestly. “You look so fucking perfect like this.” You huffed softly as you hooked your legs around Sebastian’s hips to tug him closer, and he hummed at the same time he looped one of his hands under your thigh to hold you to him as he rocked against your slick core. The friction was tantamount to perfection, but you craved more, and Sebastian knew it too.

Before you could open your mouth to complain, the freckled man ducked to press hot, wet kisses down the line of your throat, sucking and biting as he made his way down your shoulder past your collarbone. As he mouthed down your chest, he paused to tease one of your perked nipples gently between his teeth, and a pang of arousal shot through him when you arched and moaned under him. It was pure bliss– and your eyes rolled shut as your hips pressed up insistently. Sebastian ground his hips into yours for as long as he could manage before he had to scoot back to continue further, but he made up for it by dragging his nails deliciously down your thighs before he’d settled between your outstretched legs.

You made such a pretty picture spread out in the lush, satin sheets this way; with your hands fisted in the covers above your head, your legs spread on either side of him, and the lustful gaze you pinned him with, Sebastian was half convinced he’d fallen back asleep this morning and was still dreaming. He couldn’t pass up the opportunity to watch your body react to his touch, so he smiled as he dipped his head to drag the flat of his tongue up your wet folds, and the way your breath stuttered in your throat was far more enticing than it had any right to be. You attempted to push yourself up onto your elbows to watch– entirely enthralled with how Sebastian looked between your thighs– but then he took your clit between his lips and sucked, and you were pulling the sheets into your clenched fists and falling back against the pillows with a ragged moan.

Sebastian continued to toy with you that way for far too long for comfort– holding you hostage in some combined purgatory of bliss and torment as he sucked and lapped at your center. It was far too easy to reduce you to a pile of brainless mush given your fatigued, overly-sensitive state, and he was all too curious to discover how many new things you would let him get away with before you got impatient and started begging.

With gentle, attentive hands, Sebastian coaxed you into raising one of your knees up so he could throw your leg over his shoulder, instantly coiling his strong arms under your waist to hold you firmly to his unrelenting mouth. His stomach flipped at how easily you relaxed for him, and you proceeded to fight your boneless nature so you could sit up and watch him with lust-dark, hazy eyes. Sebastian loved the attention– thrived on it, really– and he broke away from your overwhelmingly wet heat to pepper chaste kisses along the smooth hollow of your leg. You were already breathing heavier– your fingers twitching around handfuls of fabric– and when Sebastian moaned and slipped his tongue out in-between kisses to lightly run the tip along soft, sensitive skin, your breath caught audibly in your chest before you shuddered out a shaky sigh.

When he first sank his teeth into the heated flesh midway up your inner thigh, he did so gently, but your hips still jerked at the sensation, and you couldn’t stop the wanton moan that slipped through your parted lips. “Fuck, Sebastian–” you groaned, your voice laced with obvious desire. You dug the heel of your foot into the middle of his back, silently imploring him to give you more, because the feeling of him marking you somewhere so sensitive was too fucking good.

Sebastian flashed you a smug grin as he pulled away, but not before planting a lingering kiss along the faint imprints of his teeth. The gesture was warm and promising– as was the way his hand squeezed your waist before letting the leg over his shoulder fall back against the mattress. He moved to splay his hands over your hips, your thighs resting comfortably over his arms, but he let them stay spread open rather than using his grip to pull you around like he usually would.

As his thumbs trailed gently along the curves of your hip bones, Sebastian leaned back down to brush another warm kiss along your inner thigh, humming at the way your muscles tensed slightly. He nuzzled up higher, then parted his lips against the soft skin to bite again, and this time he sucked steadily with the intent of leaving a dark, lasting mark there too. You moaned softly, your hips rocking up at the sensation, and as Sebastian worked yet another brand into your skin, your breath shifted into quiet panting as your hands twisted in the sheets.

Satisfied with the deep purple of the bruise and the light imprint of his teeth around it, Sebastian pulled away and dragged the flat of his tongue over his brand soothingly, breathing a low groan as he did so. He admired it for a moment longer before he mouthed wetly up your leg further, his dark, messy curls brushing against the join of your thigh.

He nuzzled closer to begin working another mark there, and the sharp sting of his lips and his teeth had you gasping– bending your free thigh up to let it fall to the side in a bid to give Sebastian all the room he wanted to keep going. He moaned encouragingly, squeezing your hips once again as you lifted them up for more, and he dragged his tongue up along the soft hollow of your thigh as his brow furrowed in concentration.

“S-Sebastian,” you gasped, trembling under the brunet’s affection. The shaky insistence to your voice caught his attention, so he leaned up enough to look at you as he licked his lips and pet your hips soothingly. Swallowing heavily, you opened your eyes and shivered, meeting his gaze almost shyly before you murmured, “I-I don’t– I don’t usually like slow stuff.”

Sebastian shifted up onto his elbows, idly drawing his palms back and forth over your flushed skin. His expression showed nothing but concern as he asked, “Do you want to stop?”

You shook your head quickly, scooting your hips minutely towards him. “N-No, no– this is fine. Good, even, I… I like this.”

Tilting his head to the side, Sebastian tried unsuccessfully to figure out what was happening, then cautiously asked, “Are you okay?”

“Yes,” you answered firmly, leaving no room for doubt. You fidgeted for a few seconds, squirming under the obvious care Sebastian was showing for you until you eventually took a breath and relented. “I like this. A lot.” The freckled man only cocked a brow at you in confusion, but before he could move to crawl over you again, you huffed and flopped back against the mattress. “I like you leaving marks on me, too.”

He mulled that over in his brain for a long moment, squinting slightly. “Okay…?”

“You fucking ass,” you wheezed out, your breath akin to an overwhelmed laugh. “It’s because it’s you, Sebastian, Merlin’s beard– I like you.”

Pressing his lips into a thin line, Sebastian stared up at you again and carefully replied, “Thanks?”

“Nevermind, I hate you,” you grumbled, slinging an arm over your face. “Forget I said anything.”

“No– hold on–” he sputtered before sitting up straight, his arms sliding out from under your thighs. You appeared to be disgruntled by the change, but you didn’t come out from hiding to complain. “I mean– we’ve been fucking for like a year. I’d hope to the Gods you can stand me by now.”

You groaned from beneath the safety of your arm shield, “I cannot believe I have to spell this out for you. I’ve been fucking you for like a year because I like you, you moonmind. Like, romantically. Very much into you, whether we’re fucking or not.”

With an uncomfortably loud click, Sebastian understood.

“Oh!” His eyes damn near popped out of his skull, his heart doing some insane acrobatics in his chest, but all of that took a backseat to the blissful realization that he wasn’t the only one with a big, gross crush. “Oh, shit, okay,” he sputtered, raking his hands through his hair. “Wow, okay. Fuck, sorry– I was totally involved in the hickey thing, my brain wasn’t on. Wow.”

“Merlin’s balls,” you groused, already trying to roll away from Sebastian’s wildly embarrassing presence. “I should not have said anything.”

“No!” Sebastian scrambled up the bed to brace himself on his hands above you, caging you between his arms while his heart hammered away against his sternum. “No, no no, you definitely should have said something, darling– shit.” He paused to try and coax you into coming out of hiding, but when you resisted him firmly, he didn’t push it. Instead, he chewed the inside of his cheek and tried to get his racing thoughts in order so he wouldn’t blurt out something completely idiotic.

“I am like, ridiculously in love with you.”

Completely idiotic.

You froze under him momentarily before peering up at him over your elbow, your wide-eyed stare bordering on horrified. Cursing under his breath, Sebastian buried his hands in his hair and stared right back, almost entirely sure he could feel his life force draining from his body.

“I-I mean– fuck, wait–”

“Are you kidding me!?” You bolted upright– narrowly avoiding cracking your skull against Sebastian’s on the way up. Your fingers clamped down on his shoulders so you could rattle him slightly as you blurted, “What the hell, Sebastian! How long?”

“I don’t know!” He threw his hands up and pointedly stared at the wall before grumbling, “I don’t fucking know, it’s not like it happened all at once. It started towards the end of our fifth-year and it just kinda… grew from there. Like a Horklump.”

Sebastian realized how shitty that euphemism was when your mouth fell open in utter disbelief. “Did you seriously just compare your feelings for me to a fungus?”

“Look, I’m sorry, okay?” He sat back on his heels, crossing his arms stiffly over his bare chest as he returned to staring at anything but you.

“For what, exactly?” You ran a trembling hand through your unruly hair, then dropped your gaze to the sheets. “For returning my feelings? Or for not saying anything before right now?” Sebastian just shrugged unhelpfully with his lips pursed. Groaning loudly, you flopped back onto the bed and stared at the ceiling for a minute, your irritated, murder face back in full swing.

Just as Sebastian was starting to get worried by the awkward silence— doing his best not to fidget— you nodded to yourself and announced, “We should date each other.”

“…Come again?”

“We should date each other,” you repeated firmly, leaning up on your elbows again and exuding a confidence that had seemingly come out of nowhere. “I like you, you love me–” Sebastian did his best to not choke on his own tongue, “–we spend so much time together that we’re basically dating anyways. At least, Imelda seems to think so… it seems like a good enough idea to me, if you’re interested.”

It took Sebastian a few seconds to untangle his tongue enough to reply, but when he did, all he could do was croak, “You want to date me?”

“Yes. I’d like that.”

“…Are you high? Did you smoke Mallowsweet on your way here?”

You groaned and tipped your head back between your shoulders, very clearly searching for some semblance of patience. “I’m high on sleep deprivation, yes, but that doesn’t make my feelings any less real. They’re there whether I’ve slept or not. It’s actually hell.”

Sebastian was still flabbergasted, staring down at you helplessly. “Why are you bringing this up now?”

“I don’t know! I didn’t mean to full-on confess or anything, it just kind of came out that way. You were leaving hickeys on me, and I realized that whenever I wake up tomorrow, I’m gonna feel them and see them and remember how you fucking appeared out of nowhere right when I was wondering if you’d be pissed if I snuck into your dorm at the ass crack of dawn– and then I’ll remember how good you looked leaving them on me and how I totally wanted you to do slow mushy lovey sex stuff to me, and then I’ll probably sleep like shit for weeks fantasizing about that, and–”

“Okay, alright, damn,” Sebastian interjected, his face flushed an impressively dark shade of red.

“You asked,” you mumbled as you half-heartedly picked at the sheets.

“I did, yeah.” Licking his lips quickly, Sebastian reached forward to rest his hand over yours, dragging his thumb along your knuckles soothingly. “I’d really, really like that. A lot, if I’m being honest. I’ve kind of dreamt about it for a while now.”

Your sheepish smile transformed rapidly into something purely elated, and you flipped your hand over to intertwine your fingers with his own as you playfully mused, “Not the only thing you’ve been dreaming about, apparently.”

Sebastian laughed again, and this time it was less nervous and more breathless with relief. He leaned forward to brush his lips against yours, resting his free hand on your warm cheek, and you instantly relaxed for him as you tilted your chin up into the kiss as you gave his fingers a tentative squeeze.

You fell back onto the bed again as you tugged Sebastian over you, loosely hooking your legs around his hips to keep him close. The brunet groaned and leaned into you, and when you threaded your fingers into his hair and pulled him into another kiss, he slipped his tongue between your lips with a shaky sigh– all too eager to put his hands all over you. Luckily you seemed to be of like mind, moaning against his mouth before pulling back just enough to whisper, “Touch me, please.”

Sebastian nodded ardently and nipped at your flushed lips, shifting his weight to free up his hands so he could better run his palms along your sides. He squeezed gently before dragging one hand down to your still-slick heat, expertly seeking out your tiny bundle of nerves in a bid to reduce you to a mewling, gasping mess. Your spine rounded towards him as soon as he found it– an airy moan ripping from your throat as he pressed tight circles around the nub– and Sebastian swallowed your keening noises greedily.

“Why are you still wearing these?” You murmured against his plush lips as your finger slipped beneath the waistband of his briefs, tugging softly to convey your request.

There was no muffling his smug bark of laughter, and a feline smile split his face as he pulled back just enough to plant a featherlight kiss on the tip of your nose. “So impatient,” he teased, intentionally ignoring your hand on his undergarments in favor of sliding one of his skilled fingers through your folds. He replaced the missing finger against your clit with his thumb at the same time he inserted a digit inside of your pulsing walls, and the feeling had your head falling back as your lips parted around a stuttered gasp, your thighs tightening impossibly further around his waist.

Undeterred, you blindly wiggled your hand under the hem of Sebastian’s underwear and tugged his arousal out with a practiced flick of your wrist. You wrapped your fingers around his girth and gave him a long, tight stroke– squeezing the head in the way you knew he liked– which in turn earned you a rough, wavering moan. Matching Sebastian’s pace was easy, and you stroked him steadily as you leaned up to seal your lips over his pulse to begin working a dark hickey of your own into his sweaty, freckled skin.

Resting his weight on his free arm, Sebastian leaned closer as he sighed heavily while his brown eyes fluttered shut from the way your mouth felt on his neck. He rocked his hips into your hand and pumped his fingers a few more times inside of you before he was withdrawing the digits to push his briefs down all the way. You merely chuckled against his throat, pulling off of the fresh, blossoming mark with a satisfied hum before you laved your tongue over it.

Once Sebastian had finally wrestled off his briefs and settled over you again, you tugged him by the neck back into a hungry kiss, and he groaned deeply at the way you moved perfectly against him. As you curled your tongue between his lips, your hands traversed down the broad expanse of his toned back to feel as much of him as you could, pawing encouragingly at his lower back to guide him into a languid, grinding rhythm against you.

Sebastian let himself follow your lead for a few slow thrusts, but the way your skin felt against his– coupled with the way your quiet moans sounded muffled against his lips– was too tempting to overlook for long. Following a brief, bitey kiss, Sebastian dropped his hand between your legs once again to press at your wet, warm entrance. You shivered at the way his fingers felt against you as he coaxed you into relaxing, and your nails dug into his sculpted shoulders when he mercifully worked two of his thick digits inside of you. A string of moans and praises alike fell from your lips as your head lolled back against the pillows, and the remnants of Sebastian’s restraint began to slip away as a result.

“Fuck, darling,” he keened breathlessly, unable to take his eyes off of your face as your expression shifted into one of pure pleasure. His buried his fingers to the knuckles, utterly overwhelmed at how tight you were, and he nudged his nose against your cheek as he murmured, “You look so fucking good right now…”

“Y-You may have mentioned that, yeah,” you laughed against his sweat-slick skin, blinking affectionately up at your now-boyfriend as he took in your pliant body beneath him, and the thought imbued you with a fresh sense of desire that you were desperate to act on. “Come on, I want you inside me already.”

With a wheezy laugh, Sebastian nodded and ducked his head to catch your lips again as he started thrusting his fingers into your pulsing heat. He nibbled gently at your bottom lip when he buried his fingers deep to curl them towards your stomach, which in turn earned him a squeaky little moan that was immediately followed by an impatient wriggle of your hips. Your legs were trembling with barely contained want as you spread them further, and Sebastian took full advantage of the newly acquired space to readjust himself into a more comfortable position.

By the time you were panting against him and rocking back onto his fingers, Sebastian was more than ready to move things along. He slid his fingers out and pulled away with another quick kiss before sitting up to steady his cock at your entrance. You helpfully wrapped your legs around his waist again, angling your hips towards him with a coy smile on your face until you felt the head of his achingly hard member bump against you. Sebastian flashed you a doting smile in return, and with an unhurried roll of his hips, he was sinking into you with a throaty groan that made your hair stand on end.

“F-Fuck, you feel so warm– you’re perfect, darling,” he grit through his clenched teeth, plunging himself deeper inch by inch until he had bottomed out completely inside of you. The way your walls fluttered around him made him dizzy with need, but he noted the tension in your shoulders and forced himself to maintain his slow pace so you could get acclimated to the feeling. Sebastian was practically fluent in your stubborn body language by now, and he was nothing if not determined to get you to relax completely.

Rather than thrusting deeper, Sebastian sighed and licked his lips as he glanced up at your face. You were an incredibly tense person on the best of days, but when you were running on fumes like this, he found it to be even harder to get you to release the mountain of stress you seemingly carried with you at all times. While he was all too used to the frown lines that so frequently cropped up between your brows, seeing them now just made Sebastian want to be even gentler with you– even more careful.

He lightly nudged your head aside and set to dragging hot, wet kisses down the column of your throat, moaning wantonly at the bare salt of your sweat on his tongue. You shivered and gasped, tilting your head to the side with a low sigh to grant the brunet more access, and before long the combined feeling of Sebastian’s tongue and lips on your neck had you melting under him completely with your eyes blissfully closed.

“That feels… really good,” you murmured with a low voice. It was pure rapture to feel Sebastian this way; moving slowly inside of you, his lips dancing down your throat and nipping softly at the skin there. His hands eventually crept up the pillows to tangle in your hair, and the enticing feeling of his nails scraping against your scalp was enough to have you tightening around his cock a fraction.

The praise sent a bolt of confidence through Sebastian, and he moved from your neck back to your lips to slot your mouths together again. He gingerly pulled his hips back before rolling them forward, and when you moved down against him with a shaky breath, it was all the go-ahead he needed to keep going.

The rhythm he fell into was slow and steady, moving inside you with long, easy thrusts while he ground against your ass every time he buried himself deep. His eyes remained trained on your face, your expression clearly showing how pleased you were to be taken care of. You weren’t squirming in blatant pleasure yet, but Sebastian figured this was a good enough first step.

“C’mon, Sebastian– you’re putting me to sleep here,” you mumbled playfully, letting your arms rest above your head in the way Sebastian loved to see. His tempo faltered slightly, but your mischievous grin betrayed the legitimacy of the claim; he should’ve known you were simply teasing him, especially when he knew you always got a kick out of taunting him.

“Oh yeah?” He practically purred, sitting back on his heels to wrap his hands around your hips as he hauled you aggressively into his lap.

You adjusted to him easily, wiggling your hips in Sebastian’s grasp in a bid to spur him onward. “Yeah… jeez, Sallow, you had one job. Tsk tsk.”

“Well, shit.” He grinned wickedly down at you as he rolled his hips back, pulling almost all the way out and relishing in the way your face fell briefly. He hovered there for a long, torturous second before he snapped his hips back into you, using his grip to hold you down on his cock as he ground deeper and harder than before. You were left gasping at the feeling, your head falling back as your fingers twisted in the sheets, and before you could recover, Sebastian rasped, “Guess I should fuck you better then, huh?”

Without giving you room to breathe, Sebastian kept up his agonizingly slow pace, easily pulling you back onto his cock with every firm thrust. He fucked into you evenly– his strong hands controlling the rhythm in the way he knew drove you crazy– and it earned him a cacophony of shaky moans that fell from your flushed, bitten lips.

“Yeah,” you replied finally, your voice tight and shaky. “You have to keep me up all morning, remember?”

It was a simple enough statement, but the way it rolled off of your tongue made it sound absolutely filthy. Your raspy voice was dripping with lust, your hot breath panting out between your parted lips, and that was more than enough to light a fire in Sebastian’s blood.

Groaning roughly, Sebastian paused long enough to hook his arms under your knees to haul them easily over his shoulders. You gasped as the movement lifted you off of your hips– then again when he nipped sharply at the inside of your knee before sucking hard enough to leave another flushed bruise there. The sensation had you squirming in Sebastian’s lap to the best of your ability, moaning breathlessly as he ground into you with a low rumble.

Once he was satisfied with his mark, the freckled man rubbed his hands slowly down your tense thighs, leaning over you on his hands again so you were effectively bent back and pressed against the sheets. Sebastian leaned more of his weight into you– sinking deeper– and just as you were opening your mouth to urge him on, he started moving again.

He picked up his pace from before easily, but now, every slow, hard thrust stuffed you full of him, and it didn’t take him long to find the angle that had you gasping sweet little moans with every shaky breath.

Writhing under him, you arched your back and gasped Sebastian’s name as your hands tightened in the covers above your head and pulled ardently. He was fucking you slowly– but at this angle everything felt so intense– enough so that any teasing pretense you’d previously had was quickly washed away beneath constant, steady waves of pleasure. Your toes curled in the air behind him as your thighs quivered and flexed against his chest, but beyond that, you were entirely at his mercy.

An animalistic sound reverberated from deep within Sebastian’s chest, and his own fingers gripped the sheets on either side of your head. The view he had of you was fucking insane; between the incredible face you were making, the way every thrust sent electric little sparks all throughout the both of you, and the way your cunt tightened around his cock with every deep thrust– he couldn’t help but moan your name, brainless praises falling from his lips whenever he could string the words together.

“S-Sebastian,” you gasped, shakily riding your hips up against the brunet’s to meet his every thrust with keening moans. “Sebastian, fuck– more, more, please–”

He made a soft, broken sound at that, then shrugged your knees off his shoulders to let them fall into the bends of his elbows instead. Surging forward, he captured your lips with his and slipped his tongue between them, and you took full advantage of the closer proximity by burying your fingers in his messy, brown curls and pulling him impossibly closer.

With you bent nearly in half this way, your knees almost touched the sheets and in turn gave Sebastian the room to pull back farther and thrust deeper– managing to maintain his steady rhythm and simultaneously drag his cock hard all along your sweet spot. You were positively shaking under him, gasping pretty, noisy little sounds into your shared kiss as you wound your fingers restlessly through his hair and pulled just to have something to hold onto. Sebastian squeezed his eyes shut and pumped his hips harder, his self-control stretched thin by how perfect you were.

How you looked, how you sounded, how you felt… he wanted more of you– more of the loud, pleading moans that tumbled from your kiss-swollen lips.

“Gods, darling–” Sebastian leaned down and sank his teeth into the crook of your neck, pressing his body against yours as much as he could. You bucked up against him and cried out at the sharp, sweet sting of your lover’s teeth, your head writhing against the pillows frantically as your hands fisted in his hair so you could press his face encouragingly against your flushed throat. It pulled a brutal groan from Sebastian as he bit harder, sucking yet another dark bruise into your skin, and the sound you made in response was enough to send his mind spinning.

Your voice echoed off the walls of the bedroom, your loud moans and cries of his name falling freely from your lips as Sebastian marked you mercilessly. The ragged sounds coming out of him almost sounded like growls muffled against your throat, and the feeling of being so full had you arching your back clean off the mattress. Your nails raked viciously down his neck and shoulders before digging into his strong biceps, but the sting from the welting lines only served to rile him up further.

When you threw your head to the side and began shaking, your voice cracking as you wailed for Sebastian in the way that told him you were close, he pulled his arm out from under your trembling thigh to plant his thumb firmly against your clit and began rubbing tight circles against the overly-sensitive bundle of nerves. As he brought you closer to your climax, gasping filthy praises between stuttered moans, Sebastian sped up his pace until he was pounding his cock into you, doing his best to keep you bent at that perfect angle as he did so. Your entire body seemingly snapped off the bed– arched tight and clinging hard to his larger frame as you clawed your nails down his arms– and your airy voice rose higher and transformed into a desperate, overwhelmed scream that cracked and made Sebastian’s brain go completely blank.

You shook apart entirely in Sebastian’s arms, tight and blindingly hot around his cock, squirming beautifully under him as he fucked you through your orgasm. Your slick coated his shaft as he relentlessly pumped into you, until the thunderous rush of his own climax crashed down around him. Warm, thick ropes of his cum filled you as he emptied himself inside, and Sebastian swore nothing on this Earth could ever hold a candle to how marvelous the feeling was.

He was vaguely aware of himself moaning your name over and over again– stammering out mumbled praises of good, so good darling, fuck. His hands gripped your hips tight as he curled over you and clung to you for dear life while he mouthed brainlessly against your heated skin. It took both of you a few long minutes to come down from your peaks; you with your arm slung over your eyes, and Sebastian slowly wrapping himself tighter and tighter around you to gather you closer. Even once the trembling had subsided, he couldn’t find a good enough reason to move. He twitched his hips back to pull out– mostly for your sake– but that was about all he could manage.

“Holy shit,” you rasped out after a while, catching Sebastian’s bleary attention. He blinked up at you and watched as you dropped your arm above your head to stare up at the ceiling, and he hungrily took in the steady rise and fall of your bare chest as you caught your breath.

He snorted softly and dragged his palms along your still shaking thighs– still loosely draped around his waist. “You alright?” There was something to be said about how pleased he was by the low, smokey sound of his own voice, and evidently you were too, considering how it sent more shivers up your spine. You nodded though, tugging at his shoulder to silently urge him closer.

Sebastian slithered up until he was close enough to catch your lips, allowing you to pull him into a lazy, sated kiss while your fingers combed through his tangled curls. All too graciously, he melted against you– for once not fighting the desire to affectionately trail his knuckles down the line of your jaw. After a few minutes of languid kissing and mindless touching, Sebastian rolled to the side and let you readjust so you were laying on your side with your back to his chest, giving him the chance to wind his arms around your waist and hold you against him.

He knew he was meant to be keeping you awake leading up to Potions class, but a few minutes of rest wouldn’t hurt. Beyond a herd of Thestrals stampeding through the room, Sebastian sorely doubted that anything could drag him away from this moment with you. He’d waited long enough for it as it was.

—

After turning your assignment in and sitting through a particularly dreadful lesson for an hour, you’d finally been free’d from the shackles of the education system for the weekend, and you’d quickly found yourself sprawled across Sebastian’s bed with the curtains drawn. You were currently dead asleep and likely to stay that way for a while, but the brunet didn’t mind in the slightest. He wasn’t particularly tired, but he was especially interested in lengthy cuddling with his girlfriend, so he had no problem with the current arrangement.

With his fingers tangled idly in your sleep-mussed hair, Sebastian watched as the bright streaks of daylight moved across the ceiling while you used his chest as a pillow, far too content to be bothered by how damn long it took to get to this point.
