Shinsou immediately took off his mask as he entered his apartment. He huffed a sigh of relief as he completed his first week of Pro-Hero patrolling. He thought it’d be the same as some of the sidekick work he completed with Aizawa during his third year at UA, but it was nowhere near the sort. It was nothing he couldn’t handle, but he was more than happy to be at home for the weekend. He was more than ready to spend the next two days relaxing with his beloved boyfriend and hero partner. “You’ve got to be kidding me!” Shinsou heard Kaminari nearly shouting in frustration, something that was incredibly rare and out of character for the budding hero. “No, officer I promise you I sent the report in last night! No, seriously, don’t put me on hold. I promise you I can -” Shinsou had guessed that the officer on the phone had gone against Kaminari’s wishes, considering the next phrase Kaminari spoke was barely understandable, but incredibly audible. Shinsou calmly stripped off most of his hero costume, leaving him in a black shirt and black pants. He slowly walked over to their shared bedroom and tapped on the door.
“Denki? I’m home.” He spoke as he opened the door, concerned by what he saw. Loads of papers scattered across their in-bedroom office desk and a rarely angry Kaminari about to throw his phone to the ground. Kaminari turned his head to see Shinsou coming in and near instantly tried to cover up his anger.
“Hitoshi! Hey, babe! How was patrolling?”
“Well, I’m glad it’s the weekend. What’s more important is what’s going on with you. You’re never angry, D.” Kaminari tried once more to shrug everything off, giving a look to say that everything was going fine. But Shinsou could see straight through him, his boyfriend was never good at lying about whether or not he was fine.
“I filled out this super long incident report from a hostage situation last week to send into the police station. Now they’re saying they never received it. So I have to do the whole damn thing all over again before the villains’ trial or the station’s going to get a whole bunch of bad publicity. That, of which, will fall onto me. They’ll never want to help me with a mission again!” Kaminari rambled to the point of speed talking as he paced around the room, as if his boyfriend wasn’t with him. Shinsou walked over towards Kaminari and placed his hands firmly on his shoulders, holding the shorter one in place.
“Denki, breathe. You’ll short circuit if you work yourself up this much.” His voice was low and rough when he spoke, but Kaminari understood the genuine concern underneath. He sighed and slowly walked over to the bed, letting himself fall and lay face flat on top of the comforter. It humored Shinso a bit, seeing how Kaminari was able to make such a joke out of his own emotions. Regardless of that, he was still incredibly concerned. He walks over to the bed and lays down on his back, turning his head to face Kaminari. “Have you ever thought of taking a break?”
“You can’t just take a break from being a hero. I have to be responsible now. Not gonna lie, it kind of sucks! It makes me miss the days at UA where I could go brainless and not feel like I’m risking people’s lives by doing so.” Brainless. That word immediately gave Shinsou an idea. He’d have to ask first, make sure everything was okay with Kaminari and that he’d feel comfortable with whatever would happen. But if he was okay with it, Shinsou had something he would love to try.
“Maybe you can’t take a break for long. But, I might have an idea on how to make you feel better.” Shinsou cooed, his low, raspy voice slowly nearing Kaminari’s ear. He leaned upward from the bed and sat gently atop the other’s lower back, beginning to knead into his tense shoulders. Kaminari let out an exhale at the contact, needing something...anything to distract him from the discourse going on in his mind.
“What were you thinking?” Poor Kaminari. So incredibly oblivious. Shinsou ran a hand through the yellow hair, raising another sigh of content from the hero beneath him. He slowly lowered his hands back down to Kaminari’s shoulders, then his back, then his lower back.
“Well, clearly this paperwork thing has you stressed out. You said you missed the times where you could go brainless and feel no judgement. What you seem to have forgotten, Denki, is that you have an amazing boyfriend who knows how to do just that.” Kaminari paused, turning his head to the side so he could face Shinsou as much as possible. They had talked before about using their quirks in the bedroom, even went through with using Kaminari’s, but they had never had a thorough conversation about using Shinsou’s quirk in that way. He definitely wouldn’t mind it. He was already the more submissive one so it’s not like much would change. But a part of him longed for that warm, fuzzy feeling he’d get after going too many rounds. That mix of pain and pleasure where your head feels like it’s in the clouds and you can barely form a proper sentence. To feel like that the entire time? Sounded good to him.
“You’re talking about brainwashing me and then fucking me...right?” Kaminari spoke candidly, earning a small laugh from the other. Shinsou hopped off of Kaminari and used his strength to turn the shorter one onto his back.
“That’s exactly what I was thinking. Is that okay with you?” Kaminari’s breath hitched at the sudden movements. But as soon as he looked up at Shinsou, who glared down at him with the perfect mix of gentle admiration and fiery lust, he could already feel himself getting hard. Without a second thought, Kaminari leaned up and began stripping off his shirt. He leaned up and collided his lips with Shinsou’s, gently cupping his face as he did so.
“Fuck yeah, it’s okay with me.” Kaminari quickly responded before smashing their lips together once more. He didn’t want it right away, though. He wanted to feel his partner grow more and more feral, knowing it’d make the payoff that much better. Shinsou started stripping off his clothes as well, inviting his tongue into Kaminari’s mouth. The two couldn’t keep their hands off of each other. Kaminari went to wrap his arms around Shinsou’s neck, but was pushed down onto the bed in the blink of an eye. The psychic hero quickly stripped off his pants, leaving him only in boxers. He slowly snaked up Kaminari’s body, kissing and sucking on his exposed skin before getting to the waistline of the other’s pants. He looks up at Kaminari, a little hesitant at what they’re about to do.
“Are you sure you’re okay with this? Because once I start, you won’t be able to do anything unless I tell you to.”
“Yeah, I’m okay with it! You know what I like and what I don’t. I trust you, ‘Toshi.” Kaminari smiled as he responded. Damn, Shinsou loved that smile. There was something about the way Kaminari’s usually positive attitude contrasted his quiet and rough demeanor. An ‘opposites attract’ sort of thing that others were confused about when the pair first made things official. But it was beautiful to them. Shinsou took a deep breath, ready to activate his quirk; the second Kaminari answered his next question.
“So, are you going to let me in?” Kaminari gulped, both nervous and excited about what was about to happen. He’d feel everything, but he knew it’d be different. Would he even be able to say anything? It didn’t matter. He needed the stress relief and he needed it now.
“Yeah, I’m -” Kaminari’s response was interrupted with his own choked breath as the quirk flipped a switch in his brain. It felt weird at first. His head leaned back as he felt all the tension in his body leaving him. His head felt light and fuzzy, like a freezing body being covered with a blanket. Nothing but a pure wave of relief. Shinsou smiled, tucking a strand of his boyfriend’s hair behind his now blank and pliant face.
“God, you’re beautiful like this. Why don’t you take these boxers off and stroke yourself for me, baby.” Kaminari immediately followed his words, not like he’d be able to do anything else. An uncontrollable sigh left his lips as Kaminari began stroking, starting slow at first. Shinsou snaked up the boy’s body and stripped off his boxers, letting his hard on free itself. “I’m gonna fuck that pretty mouth of yours so well, baby. You’re gonna take me in your mouth, aren’t you?” As he heard those words, Kaminari wrapped his lips around the length and began working his tongue everywhere he could, his mind relishing in the pleased grunts coming from the man above him. As Shinsou began to thrust into Kaminari’s mouth, the electric hero instinctively picked up his stroking pace.
Their moans quickly began to fill the room. Kaminari unable to hold back and Shinsou unable to give a shit about who heard the two of them. “I’d ask how you were feeling, but you can’t talk with my cock in your mouth, can you?” Shinsou groaned out, his thrusts growing rougher and less rhythmic. He wanted more, so much more. He had to be inside Kaminari and he had to be inside of him soon. Much to both of their disappointment, Shinsou took his cock out of Kaminari’s mouth as he leaned over to grab a bottle of lube from their dresser drawer. He placed the bottle in Kaminari’s hand and leaned down to whisper in his ear. “Here’s what I want you to do. You’re going to lube up those fingers and fuck yourself open for me, and I’m going to stroke this cock while I watch. You won’t stop until I say so. You won’t come until I say so. And don’t hold back, I love the noises you make for me.” That last sentence earned a moaned cry from the other. He felt so fuzzy and light in his head, but his body felt like it was going to sink into the bed. If he weren’t so focused on pleasing himself and his boyfriend, Kaminari swore he’d be able to fall asleep like this. He followed every one of Shinsou’s requests, his pleasure spiking as he felt his own fingers enter him.
Seeing Kaminari so obedient only made Shinsou want him more. He began to stroke himself, watching every inch of Kaminari’s twitch and tense up as he moved his fingers in and out. Neither of them started off gently, wanting nothing more than to reach that peak of release. Shinsou’s grunts became especially loud, signalling that he was close to release. But he wouldn’t let himself come before getting to feel Kaminari’s tight hole clench around him. “Stop, baby. You’re open and ready for me, aren’t you?” Yes, Kaminari thought to himself. I am more than ready...please. He wanted to scream and beg so badly, yet he couldn’t say a word. Shinsou looked down at Kaminari’s lubed up hole, biting his lip in anticipation. Shinsou lined his cock up to the entrance, slowly thrusting into Kaminari inch by inch. Kaminari, unable to hold back his noises, yelped in a mix of pain and pleasure. With barely any movement, he could already feel the tingly, bubbly feeling of release rising in his stomach. He didn’t know how much longer he’d last. Once Shinsou had fully entered him, he began to slowly move in and out. He didn’t want to be slow, however. He craved the faces his boyfriend made when his mind was being blown. “God, you’re so tight around me. How good does it feel, baby?”
“S-so....hot. S-so good.” Given he was asked to speak, Kaminari was relieved to finally tell his partner how amazing everything felt. The pleasure coursing through his veins was thicker than his own blood. He even started to feel small sparks of electricity crackling around his body, heightening every sensation. Shinsou noticed this electricity, nearly getting shocked by the volts surrounding them.
“You’re going to short circuit, aren’t you? Get all dumb for me? That’s exactly what you wanted, darling. I promise you you’ll get it.” Shinsou could barely get these words up as he started to thrust rougher and deeper into Kaminari, brushing up against his prostate. Their moans skyrocketed as the two reached their climax together, Kaminari bringing a mild shock to the both of them as they did so. Tired and pleasure-filled, Shinsou lifted the control on Kaminari and collapsed next to him on the bed.
“‘Toshi….h-holy shit.”
“Better?”
“S-so much better..I can b-barely speak.” Shinsou laughed as he went to grab a towel, cleaning Kaminari off with gentle care. He laid back down next to the younger hero and covered the both of them with a blanket as he snuggled close next to him.
“Good. Get some sleep, baby, we’ll worry about your paperwork later.”
