A/n: Hello my sweets! Unfortunately, I got locked out of my old blog account, so I had to make a new one! So, chances of you having seen this before are high as it's on my old account! (I am so sad about it honestly). But I am going through all my old accounts posts and reuploading them here! I hope you can still enjoy my works!

______________________________________________________________

"Soooo? Ya gonna tell him or not, Y/n?!" Karaku laughed while rocking back and forth next to you as the two of you stayed guard outside the hideout. Your eye twitched in annoyance as you shot the demon a dark glare, causing the sly grin on his face to grow as he licked his lips. "Ya know I could always help fill out this secret pleasure of yours~" He teased, leaning closer to your form. "You do that and Sekido will torture you for days." You warned, your arms crossed as you sat on the porch. The demon of pleasure just laughs, plopping down next to you with amusement as he rests his chin in his palm. "It's pretty convenient that your lover has the ability to produce lightning whenever he wants with that staff of his~" You growl as you roughly hit Karaku in the gut causing him to whine but laugh as he falls backward.

"It's not funny Karaku! Ever since that day, we haven't been able to look each other in the eye!" You yelled, a giant huff leaving your chest. About two weeks ago, you all had been assigned a mission to take care of some demon slayers, which wasn't hard as you all destroyed them within minutes. No, the problem happened when your boyfriend Sekido forgot that you were right in the way of his attack, causing you to get electrocuted along with the humans surrounding you. When Sekido noticed, he ran towards you, scolding you for being so careless, and of course, he was concerned that he had hurt you. However, he would never say that to your face. So, imagine his surprise when he saw you on your knees, body twitching as you looked up at the sky with glossy eyes, a deep red dusting your cheeks as drool slipped from your mouth. Since then, neither of you has talked or made eye contact with each other. You were so embarrassed that you decided to sleep in Aizetsu's room.

Your cheeks burn red at the memory, tears pricking the corner of your eyes from embarrassment as Karaku continues to laugh at you, wrapping an arm around your shoulder to tug you closer to him. "Hey! Hey! It's okay, Y/n no need to become so shy~" He teased, poking your cheek while you whined and covered your face with your hands. "What is going on out here?" A gruff and angry voice called from behind the two of you, causing both of your bodies to freeze. Slowly, the two of you looked back to see your boyfriend Sekido standing just inches behind you, his face one of pure anger as he grits his teeth, jaw clenching as his eyes glared daggers at his fellow clone's arm that had been wrapped around you for way too long. Karaku, getting the message, quickly removes his arm from your shoulders, putting his hands up in self-defense as he tries to excuse his actions.

"Easy Sekido! I was just trying to comfort Y/n is all!" The demon cries innocently, not wanting to deal with Sekido's wrath. Your boyfriend doesn't seem to like his clone's answer as his staff starts sparking, his jaw tightening even more as a vein starts to pop from the side of his neck. You panic, not wanting Karaku to suffer for trying to help you through your embarrassing predicament. "W-wait Sekido!" You cry, reaching a hand out towards the demon whose rage-filled eyes quickly lock with yours, causing you to stiffen. Having not seen him for two weeks, you glance away nervously. "H-He had no bad intentions, honest! It's my fault…" You whispered the last part, a bit defeated as your shoulder slumped, an action that did not go unnoticed by piercing red eyes. Sekido was silent for a moment before growling as he went and grabbed your wrist, catching you by surprise as he roughly lifted you from the porch, dragging you inside the hideout.

"S-Sekido?!" You tried to call, but he ignored you, the grip on his staff tightening as he made his way to the room you both shared or at least were supposed to share, considering you haven't come to bed for two weeks now, and it only fueled the demon's anger. Once he reached the room, you watched as he kicked the door open, practically breaking it as he brought you inside, tossing you onto the bed before slamming the door shut behind him. You quickly sat up as you carefully massaged your wrist while looking at him with a pout. "That really hurt, you know!" You whined, listening as his response was just an annoyed tongue-click. "How much longer?" He seethed, his eyes locked on your smaller form, the intensity causing you to shiver as you stared down at the blanket, still refusing to meet his eyes. "What do you mean?" You question trying to play innocent. This backfires as Sekido angrily slams his staff to the ground, causing waves of electricity to run through the floor.

"Don't play dumb with me dammit! You haven't come to bed in two weeks and I catch you allowing that filth to touch what belongs to me?!" He yelled, the atmosphere becoming too thick for you to breathe as you brought a hand up to your chest, heart going wild. "I-I just thought it was for the best! I mean since…the incident…” You trailed off, growing flustered once again. Sekido went silent for a minute, causing you to get curious as you slowly lifted your head. To your surprise, your boyfriend was right in front of you, his body looming over your own menacingly, an angry expression still on his face as he went and gripped your chin, making sure you couldn't avoid his gaze anymore. "Look at me dammit." He growled, red eyes locking with your e/c orbs. You felt your body shiver, having not looked into those angry eyes that always seemed to make your legs weak. Sekido didn't say anything as he slowly dragged his thumb along your bottom lip, repeating the action a few times as his eyes trailed all over your body as if trying to find any signs of injury or markings.

"Sekido I-!" Your words stop as you feel a sudden shock coming from your thighs, causing you to flinch away, failing due to your boyfriend's grasp. Sekido watches as your cheeks become flushed, more veins appearing on his temples and neck as he keeps his staff hovering above your skin, tiny sparks coming from it. "Did you truly feel good from my attack, Y/n?" He questions the image of your aroused face flashing through his mind as he bites his lip, a bit of blood leaking from having pierced the tender flesh with his sharp teeth. You look away, not answering his question, causing his rage to rise as he presses the staff to your thighs again, holding it there longer. Your body jolts as you cover your mouth, thighs shaking from the pleasurable feeling as you press your legs together. "Answer me." He demands, not finding your shyness amusing as he liked when you immediately told him the truth.

"Y-Yes!" You cried between breaths as you tried to push him away from you. "So instead of coming to me the one who shares a bed with you, the one who treats you well, the one who has caused you to scream so many times in this bed. You go to that annoying perverted piece of trash who gets to see that expression only I am allowed to see." You can tell that he was pissed as he went and released your face taking a few steps back from the bed. "Not to mention you've been sharing a room with that whiny brat." He added with detest, his mind running with all sorts of ways to punish his clones along with his lover. You, the only one who can handle his burst of rage, the one who gave her all to him. Sekido grits his teeth, fists clenching tighter as his nails start to dig into his palms, causing blood to drip onto the floor. The smell instantly gets your attention as you go to touch him. "Don't." He warns, causing you to flinch.

"Strip right now." He demands dark eyes, looking down at you. You shiver hesitating for a second but do as told not wanting him to get angry at you more than he already was. Sekido says nothing as he watches you slowly expose yourself to him, your flushed skin causing a tingle in his body as he watches your breasts bounce from being freed of their confinements. The shy expression on your face causes the tent forming in his robes to twitch as a low growl formed in his throat. "Did you show either of them your body like this? Karaku would have loved seeing your filthy body exposed to him." He speaks, watching as you discard the last piece of clothing you wore, arms coming up to shyly cover your chest and pussy, having not shown yourself to the demon in weeks. "I-I didn't show them anything!" You defend. Sekido hums as he goes and points the staff at your chest. "Move your arm. Stop acting like you're such an innocent girl. I know the truth." He barks, not liking how coy you were with him after seeing your naked body multiple times now. He found himself desiring the sight and touch of it more and more. You were just too intoxicating for him, and it angered the demon.

He watches you obediently do as you're told, causing his eyes to lighten slightly as if praising you for knowing your place. Sekido teasingly grazed both your nipples with the tip of his staff, the jingling of the metal echoing inside the room. "That you're a filthy slut." Sekido finishes his sentence as his staff sparks up, sending jolts of electricity through your squishy mounds. You toss your head back, arms falling behind you for stability as you arch your back, a loud moan of pleasure and pain sliding past your lips as your body jumps and twitches. Sekido watches as your nipples grow harder from his staff as he goes and gives the other mound equal attention, the staff showing no mercy as you start to squirm and back away. Sekido growls at this as he quickly grabs at one of your ankles, forcefully dragging your body back towards his, causing you to fall back on the bed.

His eyes darted down to the shining puddle you had left behind on the shared blanket, his heart racing as he processed what had happened. "You must enjoy this if you came from just having your nipples zapped." He muses to himself, his grip still tight on your ankle. You let out a pathetic whine as you looked up at him, tears slipping down your cheeks. Sekido loved it when you were a crying mess for him. It made him feel powerful and in control, and he loved it. "Such a filthy slut I chose as my mate." He growls, pulling your legs apart to see the sticky mess between your thighs. Sekido hums, trailing his staff slowly down your stomach, watching your eyes follow with curiosity at his next move.

"I believe you deserve some fucking punishment for avoiding me, don't you?" He Growls, the staff stopping on your clit. Your eyes went wide as you opened your mouth to protest. However, the demon did not care as he sent jolts of electricity through the sensitive bundle of nerves, causing your eyes to roll into the back of your head and mouth to open in a perfect O just for him. "Y-you avoided me too…" You managed to get out, though it was barely above a whisper. Sekido frowns at your words before upping the intensity you to release a scream as you clench the sheets, your body struggling to escape his grasp. He was angry because you were right. However, he had been avoiding you, not for the reasons you think. Something inside him had gone feral since he saw that dazed expression and how your body twitched from his attack.

For the past two weeks, Sekido had been aggressively fucking himself into his hand while picturing the scene repeatedly. He wanted to bring it up to you for so long, but every time he saw you, he felt like he would take you there on the spot, and he couldn't allow that. He would never let his clones see you so beautifully displayed the way he likes, nor would they hear the intoxicating voice that always made him cum deep inside you. "You're right…I guess I have been ignoring my filthy pet." He muttered, causing your eyes to widen from the sudden words. Usually, he never admitted when he was wrong, and for some reason, you found your pussy clenching at the sudden confession. Sekido looks at you with narrowed eyes, his dark red hues filled with anger and lust as he grits his teeth. "We'll just make it up to each other though…right Whore?" He growled his staff, sending more pleasure throughout your body. Sekido watched your pussy shake and gush as he held one of your legs in the air, his tongue sliding against his bottom lip as he watched your juices coat the sheets.

"That's the second time you've cum now…it pisses me off." He admits, tossing his staff onto the bed as he pulls his robes down, exposing his bare chest to you, eyes making sure to take it all in as saliva fills your mouth. "Fuck Sekido… you're so handsome." You whispered honestly, loving how angry he looked as he exposed himself. You watched as his eye twitched, signaling he was embarrassed by your sudden comment. "Tch shut the hell up, damn woman." He growled, tossing one of your legs over his shoulder as he pumped at his aching cock that had been dying to be inside your needy pussy. Sekido roars as he slides his cock up and down your folds, ensuring it is soaked in your pretty juices. "You're so wet now; you can take my cock, right, Y/n? Or has it been too long for a needy whore like you?" He curses as he slowly presses the tip inside, watching how your body reacts to the sudden intrusion. "Fuuuuuuck~" You cry, tossing your head back in bliss. It had been about four weeks since the two of you could fuck, and boy, did you miss the feeling of his cock.

"Tch. You're too damn tight." Your boyfriend growls as he struggles to push himself all the way in. Your walls clenched around him so hard that he almost forgot you weren't a virgin. "Sekido, I can't! It's too much right now." You whined, not thinking you could handle any more of him. Your words caused Sekido's brows to knit together, a deep frown on his face as he processed your words. 'Can't take him? Too much? Tch, fuck that.' His free hand travels back to his staff as he goes and zaps at one of your perked buds, watching your body jump from shock. He tries to push in as deep as he can, once again, this time succeeding as he lets out a deep growl, his cock twitching from how good you felt wrapped around him. "Filthy slut…your pussy just took me in so easily once I zapped your dirty body." He pants through his gritted teeth, eyes glaring down at you.

"Do you like this better than me?" He questioned, feeling himself grow jealous of his power, not liking that it affected your body more than he did. You try to form a sentence but fail as your mind starts to spin from how much pleasure you receive. Sekido scoffs at this as he begins aggressively thrusting into you, his hips meeting yours each time as he grips your hip with his free hand, his sharp teeth sinking into the plush skin as he tastes your blood. Sekido was always rough in bed, so it wasn't something you were not a stranger to; however, this time, things seemed different with the use of his powers. You whined and cried each time Sekido's hips met yours, the tip of his cock painfully pressing against your cervix.

However, whenever you tried to get away from him or cried for him to slow down, he would press his staff against your swollen clit. The pain mixing with pleasure soon consumed you as your face contorted into a fucked out expression, causing Sekido to beam internally with pride, the faintest hue rising to his cheeks as he went and pressed rough kisses to your lips, each one becoming sloppier than the last, a mix your saliva courting your lips as he went and bit down into your neck making sure to leave as many marks as he could. "I won't let you leave this room again, Y/n." He growled possessively as he pictured you sleeping cuddled up to his whiny clone, anger fueling his thrusts. Bruises lay across your chest as the demon grips at your breasts, his staff tossed once more.

"Sekido…feels so fucking good." You moaned, too fucked out to process any of the words he said. "Tch. Too fucked out on my cock and staff that you can't even hear me. Pathetic slut." He growls, feeling your walls clench at his harsh words. He knew your body like the back of his hand, having fucked you so many times, especially when he was furious. You were such a good little demon for him, so obedient, the perfect stress reliever. "Why didn't you tell me you wanted me to electrocute you? Do you think I'm a fool? A fucking idiot who you can avoid and toy around with as you please?" he doesn't let up as he feels you reach your third orgasm, your body too sensitive to handle anymore. "S-Sekido…honey," You start swallowing a giant ball of saliva as you try to get your following words out. "It's too much! Mm~ I'm too sensitive no more~" Your words reach him however they sound so pathetic that it just makes him want to ruin you even more.

"Tch, who the hell do you think you are bossing me around like that?" He growled; however, he knew that he wouldn't hold on much longer as his cock began twitching. The feeling of your pussy was too good after not having it for weeks. You made him pathetic, and he hated it. With a growl, Sekido spread your legs as far as he could, his thrusts getting sloppier as he looked down at you with hazy eyes, his mouth slightly open as he watched your eyes roll to the back of your head. "Tch. My spark," Your eyes shoot back open at the diminutive nickname he had given you a few months into your relationship. He never used it much, but you knew it was because he saved it for special times, especially when he felt so much love for you but never knew how to express it due to his angry nature.

Your eyes take a moment to focus on his features as you lock eyes with your mate. Sekido looked at you, his eyes straining with anger as he bared his teeth, your abused pussy still being pounded into as he went and grabbed your chin. "Look at me. Keep looking at only me, dammit!" He cursed as he sloppily went and circled his thumb over your clit. "I'll do every dirty thing your whore mind comes up with. Just stay here, dammit…fucking stupid woman." He whimpered out the last part before shakily reaching for his staff again as he felt his release approaching.

"Do I make myself clear?" He growled, looking at you with such possessive eyes as his staff hovered over your clit again, waiting for your response. You whimpered, nodding your head as the words refused to come out. Sekido saw how weak and fucked out you were, so he let the nonverbal response slide this time as he went and pressed the staff down, watching as his electricity flew out, causing your body immense pleasure. "Good girl…my spark." He panted, his voice waving as he gave one last deep thrust into your abused hole, his eyes rolling back as he felt his seed spray into your walls. "Dammit!" He cursed, tossing his head around from how incense the feeling was. You did the same, except this time, you felt something much more significant than any other time you had orgasmed. Sekido noticed this as he looked down at you, his eyes widening slightly as he watched your pussy spray all over his cock your juices going everywhere, as your body tensed from the sudden pleasure, mouth open but no noise coming out.

Sekido stood there staring down at your weak body, his cock growing hard again inside you, causing a hiss to leave your lips. Sekido grunts as he slowly pulls out, watching his cum leak from your twitching hole. He scoffs, pressing it back inside with one of his fingers, listening to you whine. "Tch, I know dammit." He growls as he goes and tucks you under the covers, watching your heavy eyes start to close from exhaustion. Sekido stands near the bed, a hand pressed on his cock as he curses, glaring down at you.

"I'll give you an hour dammit…after that, I'll make you do that thing again my spark."
