In dating Shinsou Hitoshi, Kaminari has learned many things about him.
He adores cats, more than most humans. Even feral cats flock to Shinsou, which makes Kaminari a little jealous, since they tend to hiss and hide from his natural electric static. Shinsou had times where he needed to be surrounded by quiet, usually when he was overtired or over social, which took Kaminari a while to adjust to. He finally figured out that putting on headphones and playing his games were the best solution to keep himself busy and Shinsou from feeling like he was going to implode.
One of the most interesting things Kaminari has learned, though, is that Shinsou likes to be in control.
Chaos makes him nervous, as does not being able to control his surroundings. As such, he tended to take the lead in bed. Kaminari had no problem with that, he was a switch at heart, maybe even leaning towards submissiveness if he was being honest with himself. Still, there were days where Kaminari wanted nothing more than to push Shinsou down and take what he wanted.
It wasn't that Kaminari never got to top, but usually Shinsou rode him, a mind-numbing experience that always left Kaminari sobbing with pleasure. But having Shinsou sit on his cock wasn't the same as the fantasies that woke him up in the middle of the night, cock aching and spilling pre onto his belly.
The fantasies where he tied Shinsou down, made him cry and beg and come over and over till he was dry were the ones that Kaminari got off too most. The mental image of Shinsou, arms over his head, eyes covered, cock slick with his own spend as Kaminari milked him for every drop was delicious. Even just the thought had Kaminari half hard in his shorts. The few times he’d tried to bring it up, though, Shinsou had flipped the situation. He would push Kaminari into the mattress and hold his wrists in a bruising grip before fucking him so hard he screamed.
Today, though, Kaminari decided it was going to end differently. He plopped into Shinsou’s lap mid tv show, catching him off guard.
“Done with your paperwork?”
“Not quite, but there's something more fun I wanted to do.” Shinsou raised an eyebrow, pausing his show.
“And what would that be?”
“You.” Kaminari giggled, knowing how cheesy the line was.
“Specifically, I want you on your back, and at my mercy.” Kaminari braced himself to be flipped onto the couch or something similar, maybe even bent over the arm, but Shinsou didn't move. Instead, the purple-haired man sucked in a breath, and started picking at his nails.
“I know you like being in control, but I'd really love to take you apart, baby.” Kaminari purred, running his fingers through Shinsou’s hair and letting his blunt nails scratch the other's scalp. It seemed to relax Shinsou, who leaned into the touch.
“I don't know…” He muttered, fidgeting.
“What’s scaring you?” Kaminari asked, pulling Shinsou closer. They hadn't talked about this yet, but Kaminari had a few guesses as to why Shinsou was so hesitant to let go.
“My quirk, it could go off without meaning to. When I'm out of control, my quirk tends to be… volatile.” Kaminari shook his head, cupping Shinsou’s face and squishing his cheeks a little.
“Even if that did happen, which it totally won't, you’d just release me right after! Your quirk doesn't scare me, Toshi, it never has. Honestly, I can't believe we haven't used it in bed yet, you taking over my body, making me cum whenever you want, edging me, fuck…” Kaminari bit his lip before shaking his head, trying to focus on the task at hand.
“Anyway! I'm not worried about you quirking me, babe! You haven't done that on accident since I met you, you have more hold on it than that.” Shinsou sighed, knowing Kaminari was right.
“And what if I hate it? I've only ever been with you, and all I do is dominate you. What if I end up not enjoying it.” Kaminari shrugged his shoulders, toying with the neck of Shinsou’s shirt.
“We have safewords for a reason, they work for both of us. If you don't like it, just tell me, and I'll let you go, ‘kay?” Shinsou nodded, quiet for a moment before surging forward to kiss Kaminari deeply. The blonde groaned and returned the kiss, giggling when Shinsou’s tongue swiped over his lips.
“Someone’s interested, then.” He purred, rolling his hips against Shinsou’s. He was half-hard and Kaminari knew Shinsou would notice.
“I'm not… opposed to trying this.”
“Think of it this way. I've trusted you to break me apart countless times and you always put me right back together afterward. You take such amazing care of me, over and over. Just trust me enough to do the same for you this time.”
Trust had always been a little difficult for the two of them, especially at first. Shinsou had been burned before, and while he was settling into a new chapter of his life with Kaminari and a found family, that lingering fear was still around. Finally, Shinsou melted into the couch, closing his eyes for a moment.
“You know I trust you, Denki.”
“With just your life, or your dick too?” Kaminari joked, pulling a snort from Shinsou.
“Both.”
“Good! Now come on!” He hopped up and took Shinsou by the hand, lacing their fingers together and tugging Shinsou to the bedroom. The purple-haired man sat on the edge of the bed and watched with wide eyes as Kaminari dug through their makeshift toy box, pulling things out and humming as he decided what he wanted. A blindfold came out, along with a well-loved ball gag, a few different vibrators, even a cocksleeve.
Shinsou swallowed thickly as Kaminari looked between two dildos, pumping them to test the thickness. His pants were suddenly a couple of sizes too tight, watching Kaminari’s pretty pink tongue poke out of his mouth as he decided. He was obviously focused on what he wanted to do, how to make Shinsou feel good, and see that got Shinsou just a little hot and bothered. Finally, Kaminari popped up, a wide smile on his face.
“Okay! Rope or cuffs, babe?” Kaminari held each up, letting Shinsou choose. He pondered for a moment, pointing out his choice.
“Cuffs it is! You okay with our usual safe words?” Shinsou nodded, feeling a bit more nervous as he scooted back on the bed.
“Are you planning on using that gag on me?” He asked, twisting his fingers the way he would in a crowd.
“If you’re okay with it! It's not for your quirk, though, Toshi, just for fun. I like how it feels when you gag me, when I can't even use words and all I can do is feel you and cry because it's so good.” Kaminari had a point, and Shinsou decided to allow it. He stripped off his own shirt, tossing it aside.
“Do your worst, kitten.” Shinsou smiled, offering his wrists.
“Oh, I will, baby. All those times you edged me to hell and back? Karma’s a little bitch.” Kaminari grinned widely, swinging his legs over Shinsou’s to sit in his lap, pushing him down flat on the mattress. Immediately his hair flared out like a halo and Kaminari’s heartbeat quickened. He was really getting to do this, to fulfill his biggest fantasy. It would be a miracle if he lasted at all once things got serious, his cock already tenting his pants.
Kaminari was gentle as he moved Shinsou where he wanted him, snapping the cuffs around one hand and looping them behind a bar on the headboard before attaching the other to Shinsou’s wrist.
“Too tight?” He asked, trying to make sure Shinsou was comfortable. Shinsou shook his head, tugging on the cuffs to test them.
“You could go tighter.” He muttered, heart skipping a beat when Kaminari did just that. The cuffs bit nicely into his wrists, just this side of painful if he moved too much. Shinsou quietly realized that he liked the feeling, trying to relax with his hands tied above his head.
“Good boy,” Kaminari whispered, focused on his next step.
“You sure you’re okay with the gag? If it's too much then I can skip it.”
“I want it, to try,” Shinsou replied, his cock aching in his pants as Kaminari brought the gag closer. The leather was worn to a softness, the gag itself bright red. He loved the way Kaminari looked in it, how the dark straps contrasted with his pale skin, how it forced him to be quiet when all he wanted to do was scream. If it felt half as good as it looked on his boyfriend, how could he say no?
“A-actually, wait a sec.” Kaminari paused, his gaze worried.
“Change your mind?” Shinsou shook his head quickly.
“Can we leave the blindfold off? If I can't talk or move, I at least want to see what's going on.” Kaminari nodded, tossing the length of silk to the side, letting it flutter to the floor.
“Of course we can, I want to make you comfortable here, for now.” The teasing tone of Kaminari’s voice wasn't missed by Shinsou, who closed his eyes as Kaminari got the gag situated. It fit tightly, Kaminari was smaller than him and they hadn't adjusted it, but it was almost relieving when his mouth was full. Kaminari may not have feared his quirk going off, but Shinsou didn't hold that same confidence in himself.
Yes, he hadn't used it on accident since he was about ten, but that didn't mean he wouldn't do it again now. The gag kept them both safe from Shinsou’s quirk, and it added another layer of reassurance that this would be okay. Something small was pressed into Shinsou’s hand, the cat toy ball that jingled when it was pushed or shaken.
“You know how to use this, right? Nod for me, Toshi.” Shinsou nodded, ringing the little bell to make his point known.
“Perfect. Use that for me when you need it, okay?” Once Kaminari was sure that Shinsou was ready, his eyes dropped to half-mast, pupils blown wide. He had Shinsou exactly where he wanted, a mouth-watering image of submission, but he had no clue where to start.
“I have so many ideas right now, baby. So many things I could do to you like this, and you’d have no choice but to take it. I think I'll do what you like to do, though.” Shinsou’s cock twitched in his sweats as Kaminari leaned down, wetly mouthing down his neck.
“You love marking me up with little bruises here, I don't know if I'll be that nice, now that I have the chance. After all, this might be my only shot, I gotta make the most of it.” Shinsou wanted to speak out, maybe complain about being covered in hickeys, but the words were stolen by the gag. Instead, he just sounded desperate, squirming a bit under Kaminari. It wasn't too far from his true feelings, his heartbeat like a hummingbird, stuttering inside his chest. Kaminari peppered kisses down the column of Shinsou’s neck, lingering longer and longer as he moved lower.
“Let's see how pretty you bruise for me.” Shinsou had never heard Kaminari speak like this, his words dark and dripping with lust. Even when he was buried inside Shinsou, he was usually begging for more, begging to come, never anything like this. The first flash of teeth against skin had Shinsou mewling, the pain shooting right to his cock. He could feel his boxers clinging to the tip with precum, only made worse with every bite mark and bruise Kaminari sucked into his skin.
Once one side was littered with marks, the blonde switched to the other, his bites almost breaking the skin. It was mind-numbing, being on this end while Kaminari used Shinsou as he pleased, teasingly grinding his cock against Shinsou every so often. Kaminari was having far too much fun, reveling in just how quickly Shinsou’s neck purpled up. It wasn't long before he almost looked like he’d been strangled, a vision that gave Kaminari ideas for next time.
Now, though, he had taken an interest in Shinsou’s weak spot. Over a year ago, they had walked into a tattoo shop together, and walked out each with new piercings. Kaminari had opted for industrials and a tongue piercing, while Shinsou got his nipples pierced. Ever since they had healed, Shinsou had been more sensitive there than ever before, and Kaminari constantly teased him about it. Shinsou usually pushed his hands away when Kaminari went to tug and rolling the buds between his fingers while they made out or fooled around, embarrassed by the sensitivity, but now… he had no choice but to lay there and take it.
“Oh, look what we have here,” Kaminari smirked, flicking one of Shinsou’s nipples with a finger and earning a little yelp.
“Let's see what I can do with these.” Kaminari’s glee was almost uncontained, Shinsou couldn't run away from his pleasure now, and he was going to take every advantage he got. Shinsou’s back arched towards Kaminari as his small fingers teased the bud, dragging the pads of the digits over it before pinching. He played with the piercing, sliding the barbell around a bit as Shinsou squirmed and moaned.
“Feeling good, baby?” The blonde asked, his tone amused. His free hand slid down Shinsou’s belly, palming his straining cock. The fabric of his sweats was already darkening with precum, almost entirely untouched.
“Fuck, you’re wet here, you must like this a lot.” Kaminari tugged Shinsou’s pants down, just enough to free his cock. It was red and swollen, jumping when Kaminari wrapped his hand around it and slowly pumped from base to tip.
“I'm going to make you cum from this, Tosh’. I'm going to make you cum with just your tits.” Kaminari’s words were almost akin to a threat, his fingers rolling Shinsou’s nipple between them.
“I'm absolutely buying clamps the minute I'm done with you, I'll leave them on you all day while we’re home, and if you touch them, I'll punish you.” Shinsou groaned, his eyes fluttering closed for a moment. The more Kaminari abused that side of his chest, the more sensitive he got, his breath coming out in pants behind the gag. Sure, he’d played with himself a little once the piercings healed, enough to know that it was dangerous to linger there, but this?
Every little bit of friction had him swallowing down his own moans, his cock pulsing against his stomach. Kaminari pointedly ignored it, suddenly switching sides. The difference was obvious, Shinsou’s body jumping back from the first touch.
“Oh, you don't get to run now baby boy. All those times you sucked me dry, every time you fucked me till I passed out? This is revenge .” Shinsou believed it, he had a habit of pushing Kaminari to the line of too much until his boyfriend couldn't even say his own name, much less control his quirk. Sure, he got shocked sometimes, but seeing Kaminari’s face, covered in cum and tears and drool, was worth it.
The blonde's mouth sealed around Shinsou’s nipple, the one swollen and sensitive from his ministrations before. The wet slide of Kaminari’s tongue over his skin was something akin to bliss if Shinsou had ever felt it, quilling the heat that had sprung up from the abuse. His fingers, though, were nothing short of little devils wrapped in pretty nail polish and innocence. They yanked on Shinsou’s piercing, pinching his nipple till it was pebbled and swollen. The juxtaposition has Shinsou’s head swimming, his hands yanking at the cuffs, desperate to touch.
It was a luxury Shinsou wasn't afforded, no matter how much he pulled at his restraints, wanting nothing more than to either push Kaminari away or pull him closer. He couldn't decide what he wanted, whether it was a break from the unending torture Kaminari was providing or to push his chest somehow deeper in that hot mouth. As it turned out, he had no choice in the matter. Kaminari popped off Shinsou’s chest with a sinfully wet sound, his lips slick.
“Let's kick this up a notch, yeah baby?” He purred, holding up two fingers and spreading them, letting a charge arc between the digits. Shinou’s eyes went wide and he moved around a bit, tugging on the cuffs. Kaminari paused a moment, watching carefully to make sure Shinsou didn't try and ring the bell pressed into his palm. No jingle. Kaminari had never been so happy to hear silence in his life . He started slowly, letting Shinsou get used to the feeling of electric charges coursing over his skin. Every zap made Shinsou twitch and groan, but he didn't pull away.
“You’re being so good for me, Hitoshi. Keep this up and I'll make you feel so good .” Kaminari knew the power was going to his head, licking a wet stripe over Shinsou’s sternum before touching one finger to his skin. The saliva helped conduct the electricity, not much stronger than your run of the mill static shock, but enough to make Shinsou’s head fall back against the pillows. Kaminari’s sparking fingers traced paths over Shinsou’s chest, edging closer and closer to his nipples but not quite getting there yet. Kaminari kept careful control over his quirk, making sure it was never enough to hurt Shinsou, just enough for him to feel. The first little zap to his nipple had Shinsou’s back arching, his hips bucking in search of contact.
“Oh, you like that, huh? I can't tell if you’re getting off on the pain, or you’re just that sensitive here.” Shinsou mewled behind the gag, no longer caring how it looked. If he seemed desperate right now, it was because he was. Having Kaminari pinch and roll his nipples had been one thing, but the electricity? Shinsou was starting to wonder if he really could cum from this. Kaminari seemed determined to make it happen, ignoring Shinsou’s cock even as it squirted precum over his abs, the tip almost purple with need.
Instead, he electrified the tip of his tongue, running it over one nipple. Shinsou swore his heart stopped for a moment when Kaminari’s tongue brushed against his piercing, the metal conducting far better than skin and setting his nerves on fire. Maybe it should have hurt, but all Shinsou could register was insane amounts of pleasure, his eyes rolling back. The teasing didn't end, though. Just as Shinsou was starting to adjust to the constant electricity running through him, Kaminari pulled away, tucking his hair behind his ear.
“God, you look amazing. So fucking good for me, I almost want to suck you off right now. But I know you can cum for me, you’re Hitoshi, you can do anything.” Something about the praise was almost as good as the wandering fingers, Shinsou squeezing his eyes shut and fighting to breathe.
“Let's turn up the watts, then.” Kaminari smiled devilishly, leaning back down and wrapping his lips around one nipple while his static coated fingers played with the other. He tugged and rolled the sensitive bud, all the while delivering small shocks that got stronger with time. He sucked on the other nipple, flicking the piercing with his tongue before adding electricity to the mix. Shinsou’s groans were music to his ears, the heady scent of something akin to ozone and cum muddling his thoughts.
Shinsou only got louder when Kaminari switched sides, letting his nails scrape over abused flesh before zapping his boyfriend. The best reactions came when Kaminari pinched one nipple while dragging his tongue piercing over the other, electricity connecting the two men. Shinsou would moan and cry and push his chest further into Kaminari’s mouth, his body shaking as he got close. Kaminari swore he wasn't far off himself, his untouched cock straining hard against his pants.
“Oh gods Toshi, please cum for me. I want to see it, please baby?” Kaminari begged, clicking his tongue piercing on his teeth before going back down on Shinsou’s chest. The strength must have gone up because Shinsou’s eyes crossed the moment the electricity started pulsing through his nipples, his cock twitching. Kaminari looked up at him with wide eyes, watching as he laved his tongue over one nipple, then the other, his fingers following. The sensations just built and built, a bonfire rising in Shinsou’s belly as the familiar tells of his orgasm made their appearance.
One final zap was the tipping point for Shinsou, the tap of Kaminari’s tongue stud to the sensitive bud on one side while the other was twisted between deft fingers. It was all too much for Shinsou to take, his body’s instincts taking over. His eyes screwed shut and he could distantly hear muffled wailing, wondering if Kaminari had come as well. Shinsou's chest heaved as his orgasm hit him, a force stronger than any punch he’d gotten in a fight.
It knocked the air from his lungs, his back rising up off the bed as his cock pulsed and sprayed cum between them. For a moment, all Shinsou could see was white, his brain running at half speed as he let the pleasure roll over him, the aftershocks making his legs pull closer to his body. He managed to shake the cat toy in his hand, unable to take any more right now. Kaminari was quick to act, springing out of his stupor to undo Shinsou’s gag.
“Holyfuckingshit.” Shinsou breathed, his words slurring.
“Babe! Are you okay? I think I went too far there, shit, do you know where you are?” A little half-smile crossed Shinsou’s lips, words catching in his throat for a moment.
“M’good, Denki, it was good.” He muttered, his voice hoarse. Shinsou slowly realized that that scream was his own, the best explanation for the roughness in his throat.
“Are you sure? Because I'm pretty sure I zapped the hell out of you, and then you screamed, and I just know the neighbors heard.” Shinsou chuckled, his head lolling to the side.
“I'm more than good, I… I don't know if I've ever come like that before.” Kaminari’s mood improved immediately, his worries assuaged for the moment.
“I wish you could have seen yourself, I nearly creamed my pants just watching you cum. Fuck…” Kaminari chewed his lip a moment, little remnants of static making his hair rise.
“Wanna keep going?” He asked, hopeful. Shinsou nodded quickly, almost embarrassed how much he wanted more.
“Oh thank gods, I need my dick inside you yesterday , or yours in me, I don't care. I just, fuck, you looked so good, and I didn't even touch myself yet.” Shinsou smiled, glancing down at his chest. Cum has splashed high on his belly, dripping and mixing with the literal puddle of pre he had leaked onto his stomach. Kaminari nearly fell off the bed in his haste to get his pants off, laying on his belly and nuzzling Shinsou’s thighs.
“I can't wait to feel you cum like that around my dick, Hitoshi.” He grinned, clearing away the mess on Shinsou’s skin with almost kitten-like laps of his tongue. Shinsou groaned, his cock already stirring with interest.
“It won't be easy, you know.”
“And what do you take me for, a quitter? Shinsou Hitoshi, I thought you knew me better!” Kaminari sat up and brought a hand to his heart in mock hurt.
“Then you’d better prove wrong, kitty.” Shinsou knew all he was doing was riling Kaminari up, but the eager look in his eyes told him it was exactly the right thing to do. And if they wound up with a complaint on their record to the building super, well, Shinsou could always talk his way out of it.
