You and Dexter were perfect for each other ā or close enough. You loved his bluntness, his dry sense of humor (which wasnāt always humor) and his demons, whatever they were. You had your suspicions, but you had yet to muster the nerve to ask him directly about them. It was so frustrating, because you prided yourself on opening controversial or inappropriate topics. You kept telling yourself that you were just afraid of losing the tension between the two of you once youād call him out on his nocturnal disappearances. Ā
Some nights, heād come home at an ungodly hour, collapsing into the bed beside you like gravity finally caught up with him. Occasionally, youād wake to his stubble brushing your cheek as he laid kisses along your face. More often than not, you were too tired to make something out of it, and usually, you also assumed heād just gotten off on something else, because he would sigh and nuzzle into you like he was still riding en endorphin rush.
You rarely engaged in a sex in the middle of the night, unless he demanded it. Once, you told him he could do whatever he wanted with you. Yours and Dexterās sex life had its own intricate taxonomy: Ā I am objectifying you right in this moment and want your body sex or my hormones are acting up sex. The list was long, really, but at the very top was something went wrong sex. That was your favorite, but too bad for you, because it wasnāt very often that you got to experience it. Dexter is very careful and focused most of the time. He doesnāt make mistakes. The bright side of that: youād never ever get tired of it. Those nights felt like Christmas. No. Better than Christmas.
One evening, he came home earlier than usual (you werenāt even asleep yet). He was so angry. So frustrated. And you wanted to help. You set aside the book you were reading (it was about a woman who fell in love with a sociopath. safe to say, it was an intriguing read) when he stormed into the room. You crawled to the foot of the bed, watching his sharp movements with wide eyes as he took off his army green shirt.
Youād always imagined yourself grinding on him while he wore his uniform. And that time was no different. But that night wasnāt about you. It was about him. Well, partly.
āCan I help?ā
āNo.ā his tone was clipped as he continued to move frantically around the room.
You werenāt sure if you should push his buttons. Your heart beat out of your chest from the nerves. Part of you thought maybe you should back off; the other part ā it thrived on the uncertainty, the thrill of not knowing how far you could push before he snapped.
āI could make you something to eatā¦ā
Horse shit. You couldnāt cook to save your life, and he knew that. But he just scoffed, the corner of his mouth twitching into a humorless smirk. Ā
āHow about a bath? I could light those lavender candles and throw in one of my bath bombs.ā
āI said no.ā Ā
You were still kneeling on the bed, dressed in your checkered shorts and a spaghetti strap tank top. Trying to act as innocently as possible.
āDo you wantāā
He finally charged toward you, cutting you off mid-sentence. āDo I need to spell it out?ā
Finally. Bait taken.
You looked up at him with wide, innocent eyes, slowly rising to your knees. The top of your head barely reached his chin, forcing you to tilt your neck to meet his gaze.
You started placing kisses along his collarbone, trailing up over his shoulder and to his neck. Your hand rested on his chest, palm splayed over his heart.
āAny chance I can sub in for one of them tonight?ā you murmured, your lips brushing against his skin.
His brows furrowed and then shot up. āThem?ā
You felt the sudden quickening of his pulse beneath your hand. You nibbled on your lower lip as you nodded.
āWhoās them?ā
Instead of answering, you tanhled your fingers into the hair at the nape of his neck and pulled him down into a kiss. It was a reassurance, a promise that youād always be there. Okay, maybe you did it because you didnāt want him to leave you. You didnāt want to activate a chain reaction.
He leaned into you, his hands sliding to your waist, holding you. When your lips parted, your forehead rested against his.
āYou tell me, Dexter. Or donāt. I donāt care. But I want you to be happy. Do whatever you need to me if thatās what it takes.ā Ā
Pathetic? Most definitely. But who cares? He secretly loved it when you got like this ā whiny, needy, entirely his.
His hand cupped your right cheek, his thumb brushing a faint vertical line against your skin, the nail scratching just enough to leave a fleeting mark. But his gaze darkened again, pupils dilating, like he was replaying unhappy memories.
He kissed you then ā hard and insistent. His hand circled your neck, his thumb pressing just underneath your ear, while the rest of his fingers gripped the other side, his pointer brushing against your earlobe. Your hand instinctively shot up, clutching his forearm as if steadying yourself for what was coming.
Long story short, he fucked you that night, like never before. And since then, youād been relying on your own version of Thorndikeās Law of Effect: if you wanted to ignite that fire in him, to get destroyed by him, you had to be a brat. Acting like you had control was the fastest way to make him prove otherwise. Sometimes you suspected he loved control more than he loved you. Youād told him that once, and heād said you were being dramatic. Again. Well, you could still weaponize it.
The problem was, Dexter was otherwise a calm and patient boyfriend. He tolerated your antics with an almost infuriating ease, whether it was leaving the windshield wipers on long after the rain stopped or overbuying carrots at the farmerās market only for him to help you eat the whole bowl of carrot salad. He even helped you find reliable owners for the stray cats that always āfollowedā you home. He was so good to you, and thatās why you always had to wait for something to go wrong. Thatās when he was at his weakest and thatās when you struck.
Todayās the day. It was Friday and you didnāt have any classes, so you hadnāt set an alarm. You usually managed to wake up before 8 am ā not too early, not too late. But this time, it wasnāt the sunlight or your internal clock that stirred you awake. It was the sound of chewing. Muffled munching, punctuated by the occasional scrape of a fork against a plate.
You cracked your eyes open, squinting as the golden rays of the early Miami morning sun flooded the room. You groaned softly and turned to look at the clock on the bedside table. 7:42. Acceptable.
Blinking the sleep away, you shifted your gaze to Dexter. He sat propped against the headboard on his side of the bed, a plate balanced on his lap, spearing pieces of egg and bacon with his fork before shoving them into his mouth.
What the fuck?
He never ate in bed. One time, when youād brought a bowl of popcorn to share during a movie night, heād almost thrown you out.
āIām not a clean freak. You just canāt even drink out of a bottle without spilling it all over the place,ā heād said. Well, he wasnāt wrong, but youād managed to convince him anyway.
Now, though? Now he was the one violating the sacred no-food-in-bed rule.
āMorning,ā you mumbled, your voice still groggy as you reached for him.
He paused, registering your movement, and turned to you. His fork hovered mid-air as his gaze softened, just enough for him to take your hand and press a kiss to your knuckles. It was a gentle gesture, the grease from his lips lingered on your skin. Ā
āHey,ā he said, offering a weak smile. His voice carried a strange edge too, almost shaky.
You watched him carefully, he turned back to his food and with a quick flick of the remote, he raised the volume on the TV you hadnāt even noticed was on. Ā Ā
The screen showed a reporter standing in front of a crime scene, her voice urgent as she rattled off details about a recent incident. They flashed an image of a man ā the criminal ā and then back to the reporter.
Your eyes darted from the TV to Dexter. His brow was drawn low, his stare almost predatory as he watched the broadcast. His jaw tightened and released, the muscles flexing as he chewed. Occasionally, his teeth ground together, producing a faint, grating sound.
He was in the mood. And it hit you.
He never ate in bed. He wanted you to provoke him. A slow smirk curled your lips.
āCareful, Dex. You might intimidate the reporter through the TV.ā
His grip on the fork tightened and chewing came to an abrupt halt. He exhaled sharply through his nose, not amused.
āNot today.ā
āDid someone leave a typo in their lab report or what?ā
He stuffed the rest of his food into his mouth without so much as glancing at you. Ā
āDrop it.ā
āOh no, did Masuka out-gross you again?ā
The plate clattered onto the bedside table with a force that made you flinch. Before you could react, he was on you. In a flash, his hand gripped your cheeks, his face hovering dangerously close to yours.
āYou think youāre funny, donāt you?ā
That was easier than you thought.
āFunny? No. I think Iām just observant.ā
His eyes narrowed, dark and unrelenting as he studied you. His grip on your cheeks tightened just enough to make your lips purse.
āIs that what you call running your mouth until you get yourself in trouble?ā
You couldnāt help it. Even with his face inches from yours, his hand firm on your cheeks, you smirked. āPlease, Dexter, youāre all bark and no bite.ā
Now you were just being annoying. He was actually all bite and no bark. His jaw ticked anyway, a muscle jumping just beneath his skin. He leaned in closer, his breath warm against your lips as his nose brushed against your cheek.
āYou really want to test that theory?ā
You tried to shrug, but his grip on you made the movement awkward.
The air between you was thick, electric. His eyes searched yours, and you finally saw that primal tweak of his.
Then, without a warning, he released your cheeks and grabbed your wrists, pinning them to the bed on either side of your head. His strength was effortless, his movement precise.
āIf you donāt come at least four times until I have to leave for work, Iām not gonna let you come for four weeks at all.ā
Shit. Four weeks is a long time. Thatās a whole month!
āNow youāre setting ultimatums?ā
āYour time is running out, you sure you want to talk back?ā
And that was your cue to finally keep your mouth shut.
āGood girl.ā He said, the words sending a jolt straight through you, and you became acutely aware of the wetness pooling in your sleep shorts.
āOn your knees. Grab the headboard.ā
You obeyed without hesitation, pressing your chest into the mattress as you shifted onto your knees, sticking your ass into the air. You felt the fabric of your shorts clinging to your slick pussy in a way that was both uncomfortable and relieving.
Dexter moved behind you, his hand brushing over your hips, the touch almost gentle before he hooked his fingers into the waistband of your shorts. He tugged them down, watching the material stick to your pussy, making his cock twitch in his pants. You squirmed under his fingers as they brushed against the skin of your thighs, leaving goosebumps in its wake.
āJesus, youāre sopping wet. Am I even surprised?ā He said, bringing his fingers to your cunt and skimming them along the center from your hole, down to your clit. As he grazed that little spot, you bucked your hips into his hand, only for him to retreat it and bring it down in a swift move, slapping your clit and sending a tingling into your stomach. You moaned, not expecting him to get rough so soon.
Then, he kneeled next to you. You were too afraid to turn your head, but you could see with your periphery vision the tent in his pants. He brought the middle finger and the ring finger of his left hand to your mouth, and you opened without hesitation, wrapping your lips around them as he slid them all the way in. For you, it was awkward from that position, the fingers hooked in the corner of your mouth, forcing it to tilt slightly.
Once he decided that they were wet enough, he removed them and the same arm reached under you, his forearm touching your stomach as his fingers, now slick with your saliva, reached your pussy. They slid between your folds with ease, the two fingers pinching your clit between, before rubbing circles into it.
The tension in your stomach coiled tighter with each movement. You squirmed under him, needing more than he was giving you, and he knew that. But when you started moving too much, he slowed, barely grazing the sensitive bundle of nerves.
āDex,ā you whined, your hips moving, trying to chase the friction he was withholding. But his only answer came in a form of a slap to your ass. Your mouth opened in a silent cry, and your hand instinctively let go of the headboard and reached for your cheek in order to sooth the pain. But before you could touch your own skin, his free hand was wrapping around your wrist, holding it high and causing your muscles to strain.
āDonāt make me tie you up. You donāt have time for that.ā
You nodded in silent obedience, and you gripped the headboard again, focused on not letting go. His hand was still teasing your clit while his other hand reached from behind and played with your hole, your slickness sticking to his fingers. For a moment, he was enjoying the feeling of it, of you on his fingers. Then he spread the wetness up and over your asshole. He only teased your back entrance, returning to your pussy and plunging his fingers inside, making your grip on the headboard tighten, as well as your walls around his fingers.
Dexterās fingers worked you expertly, curling upward to hit that spot inside you that made your eyes roll into the back of your head. The movements of both his hands were in sync, the combination driving you to the edge as he upped the pace, relentless and unforgiving his fingers thrusting deeper, while also pinching your clit harder and occasionally grazing a nail over it, sending shivers down your spine.
The room was filled with the sounds of your gasps, Dexās occasional grunts and most importantly, the squelching sounds of your drenched cunt. You were almost embarrassed by it, and Dexter made sure you felt that shame.
āListen to yourself. So messy.ā
Your response was a broken whine, your body trembling as his fingers curled just right to hit that devastatingly perfect spot again and again and again. His other hand maintained its tormenting rhythm on your clit, switching between sharp pinches and soft, tantalizing circles as your juices dripped from your hole to your clit.
Your knuckles became white from the hold you had on the headboard, your focus on not letting go and letting go at the same time. The pressure pulled you further under, and when he felt you clench around him, he pressed harder, his fingers moving with even more intensity.
āYou wanna come?ā
āYes,ā you whined, your body shaking with the overwhelming sensations.
āDonāt forget your manners, sweetheart.ā
The pressure was unbearable now, your release so close you could taste it.
āPlease, can I come?ā
āGo ahead.ā He growled, his fingers resuming his relentless pace, the wave of pleasure hitting you like a tidal force, crashing through every nerve in your body. You cried out, your body convulsing with the intensity of your climax. Your thighs trembled and your grip on the headboard faltered, but you were quick to remember to hold on, otherwise he wouldnāt let you ride it out.
Dexter worked you through the aftershocks, his fingers slowing but still keeping you riding that high until you were an overstimulated mess beneath him. When he withdrew his hand, you thought heād give you a moment to gather up, but instead, in a quick motion, he was behind you, spreading your ass and burying his face between your cheeks.
Your body twitched as you felt him press his tongue flat on your puffy clit, shaking his head from side to side before catching it between his lips and sucking on it. The stimulation too much, you even tried to pull away even though you didn't really want to. It was to no use anyway, he followed you and his hands pushed against the small of your back, limiting your movements. He kept sucking on your bundle of nerves, his nose nudging your wet opening.
The thought of him being this messy alone made you so fucking horny and needy, as if you werenāt at the maximum capacity to feel those things.
Dexter pulled another whine out of you when he tugged on your clit with his lips, pulling back until he let go with a pop.
āYou get so fucking sweet when youāre on your on your knees.ā He said before returning his tongue to your pussy, running it flat up and down your lips, spreading your cunt and mixing his spit with your juices before he slurped it all up.
Your hand itched to let go of the headboard and cover your pussy to give your swollen clit a rest, but you were afraid of what he might do if you disobeyed again.
Besides, eating you out was his favorite thing in the world, and bad things would happen if you deprived him of his favorite activities.
One time, heād made you ride him for so long until it was physically impossible for you to lift your ass. Heād proceeded to call you lazy, and had you dared, you would have slapped him.
Now, too much was at stake. He flicked his tongue against your clit repeatedly before finding your entrance and plunging it inside, the wet muscle massaging your walls. He loved your taste, he loved how you squirmed, he loved how slick and sticky you were. And you loved how animalistic he was about it, and how he didnāt care that you were overstimulated.
He dragged his tongue in and out of you, and then finally, it returned to your clit, his teeth grazing the sensitive spot. And the slightly sharp sensation was all it took to send you over the edge again. Your pelvis twitched against him, his hands squeezing the flesh of your ass, dragging his nail against you aggressively and leaving red scratch marks behind.
You loved them more than bruises. You could get bruises anywhere, sometimes they appear, and you donāt even know how. That's a common knowledge. But chafed, irritated skin? You know exactly how it gets there. You remember it. It evokes memories.
He hummed against your hot, wet flesh, the vibrations only accelerating your orgasm. You mewled, almost screamed, but you didnāt want to seem overdramatic. Your cum spilled straight into his mouth and he drank it all down as if he didnāt want to waste a single drop. He caught it on his tongue, licking you through the orgasm. Your upper body felt so numb, while down there, it was like fireworks. And when you finally started coming down, he slowed down, laying kisses over your pussy lips and your butt and your thighs. You felt the wetness his mouth left behind, your slick slowly drying on your skin. It was almost comforting, feeling him be so soft. You felt like curling up to him, falling asleep in his embrace.
āThree to go. You think you can make it?ā He asked, and you heard him move behind you, followed by the sound of his buckle as he removed his belt.
You looked at the clock. 8:02. You didnāt think you could, but even if you did, it was in his control. He was just manipulating you to think that it was yours. Or he was just mocking you. He knew you werenāt stupid.
āYou think you can?ā
The leather belt came down on your ass, to the same place heād slapped before. You made a note about checking out that bruise later.
Ā āYouāre only giving me reasons to spank the shit out of you.ā He said, dragging the belt across your ass, before touching the curved part to your pussy. Once it was gone, you waited for Dexter to hit you there too, but the blow never came.
āLet go of the headboard.ā
Your brows furrowed, but your confusion quickly disappeared when he hooked the belt around your neck, yanking you upwards, your back against his chest and his clothed cock nestled between your ass cheeks.
You subtly ground against him, making him purr into your ear, which made you smirk. He gripped both ends of the belt in one hand, while his other arm snaked around your waist, his hand slipping under your tank top and squeezing your breast. The way he pinched and tugged on your nipple made you buck into him with more force, and he reciprocated, grinding against you, giving in to his own pleasure. Then his hand disappeared from your body and you heard the sound of him spitting into his palm, before he brought it to your pussy. As if you werenāt completely drenched. He knew you loved how disgusting the thought was. How lewd you felt when he did that.
For him, this was nothing compared to the things he did during his free time.
Then without a warning, he released one end of the belt, causing you to collapse face-first into the bed. He unbuttoned his khaki pants and pulled his cock out before grabbing your arm and turning you on your back.
You finally got a good look at him - strands of hair sticking to his forehead, his eyes dark framed by lashes that looked like he'd used an eyelash curler (something you envied him). You admired him. Not just for his look, though that part was obvious. He knew he had women turning their heads in his direction. But they didnāt know the brilliant mind beneath it all. He was so clever, so undeniably smart, and that was what truly excited you. That a neat man with a compartmentalized brain like his could get so messy when it came to sex. Like now, all sweaty, his cock leaking onto the sheets. Some of the precum probably landed on your cunt too. The thought alone sent another wave of pleasure building deep in your abdomen.
He leaned down, his tongue flicking into your pussy in one swift motion before crawling over you and capturing your lips in a kiss, making you taste yourself on his tongue. His hand slid to your neck, his thumb pressing firmly against your pulse point, making you aware of how fast your heart was pounding. You moaned into his mouth as he applied a touch more pressure for a split second, giving him the chance to slide his tongue deeper into your mouth. You sucked on it, tasting the tanginess that he'd collected from your lower lips.
Without warning, with just a sublte shift of his hips, he was inside you. A low moan escaped him as he felt the tightness of your walls, and you let out a soft whimper at the stretch. He didnāt move at first. He kept kissing you and his hand slid down your body, squeezing your boob again, rolling the nipple between his fingers. Lowering his head, he wrapped his mouth around your sensitive peak, sucking gently on your tit. Your fingers tangled into his hair, your nails scratching lightly against his scalp, pulling him closer.
His teeth grazed your sensitive nub, sending a jolt through you, and in one fluid motion, his arm snaked beneath you, lifting and sitting up as he pulled you onto his lap. He started thrusting his hips into you, holding you in place, his cock gliding effortlessly along your slick walls.
Leaning forward, his lips found your other breast, his tongue tracing lazy circles around your nipple before his mouth opened wide, taking in as much of your soft flesh as he could. You arched against him, your back curving as your hads pressed his face closer, your head tipping back in ecstasy.
He kept on fucking you, hitting that sweet spot inside of you that made you dizzy. He drove his cock into you, quickening the pace, a sign that he was getting close. His arms around you tightened and then suddenly, you felt a sharp pain originating in your breast and going straight to your pussy, making you clench around. He was fucking you hard and deep, and when you looked down, you saw him still latched onto your tit, his upper lip covered in crimson.
You felt the sting from the way he was sucking on you, and when he finally removed his lips from your breast, you saw red drops dripping down your breast, the blood leaking from the bite marks where his upper teeth sank into your skin. You were mesmerized by it, and you wanted more. You pushed his face back against your sore nipple and Dexter surprisingly didnāt argue. He licked the blood off you and sucked again while ramming into you. Your body shuddered, and finally your third finish was brought on by a couple of additional thrusts of his hips. Then he laid you flat on the bed and chased his own release. You pulled him up by the chin, meeting his lips in a sloppy kiss as he fucked you hard and fast until he spilled inside of you.
Once you both came down, he was lying on top of you. You wrapped your arms around him, squeezing him affectionately, because you were so content that he was there with you.
But you were yanked out of your dreamland when he rose to his feet, making your brows furrow.
āThat was only three,ā your tone couldn't be more confused, as he headed to the bathroom.
āYeah, but I need to shower and pick new clothes to wear. Canāt go to work with your cum all over my pants.ā He came back to the bedroom with a smile on his face, as if he just hadnāt fucked the shit out of you. āLast oneās on you.ā
āOn me?ā
āYes. Make yourself cum before I leave. If you donāt, you know the consequences.ā
He gave you a quick peck on the lips before disappearing into the bathroom.
Asshole. He knew youād lost the ability to make yourself cum shortly after youād started sleeping together. But luckily, you had your stash of toys that might help you with your problem.
With the roll of your eyes, you rolled over and reached into your nightstand, but in that moment, he peeked from around the corner.
āOh, and your hands only.ā
āWhat? Thatās not fair!ā
His face dropped again.
āYou want to tell me whatās fair and what isnāt?ā
You slammed the drawer shut and fell on your back, your body bouncing on the soft bed.
āGood girl. And no cheating. Iāll keep the door open. If I so much as hear something else that isnāt your fucking scream, I swear youāll have to work your ass off to make me let you come ever again. Understood?ā
āYes.ā
āGood.ā
You hadnāt done this in a long time. It almost felt unnatural. But despite that, your fingers dropped to your clit, and you began pushing yourself over another edge. Or at least you tried. But it was pointless. You tried to squeeze your wounded breast to get that rush going, but it didnāt have that effect this time. It only made you sweaty.
He managed to finish his shower before you made yourself orgasm, obviously. When he entered the bedroom with a towel around his waist, he looked at you with feigned pity.
āAww⦠Donāt tell me my baby needs a manual to get herself off.ā
āDex, come on. You know I canāt make myself orgasm,ā you tried to reason with him, but he wasnāt going to budge.
āI canāt do two things at once, Iām only one person,ā he argued, as if it was the most logical thing in the world. āThis is for your own good. I gave you an opportunity to make it to four before I have to leave. Itās not my fault youāre not capable.ā
You huffed, bringing your fingers to your pussy again, stuffing them inside yourself and trying to fuck yourself, but again, to no avail.
He even laughed at you, and when you opened your eyes, you saw him already with his work bag slung over his shoulder, hands casually tucked in his pocket. Youād lost.
āFuck, I wish you could see yourself. So desperate. Itās like your world has been destroyed.ā
āIt kinda has.ā
He came to your side of your bed where you were still lying with your hand between your legs. He leaned over you, brushing the hair that stuck to your forehead and placing a soft kiss there.
āTake that as a lesson. You shouldnāt take a bait if you canāt handle the hook.ā
And with that he turned on his heel and left, leaving you wrecked and messy, the most agonizing four weeks of your life just now beginning.
