It was a quiet night.

Shinsou lay with his head on his arms behind him in bed as ‘The Cure’ poured softly from his stereo.

/Knock-knock!/

He rose, then opened the door to find Kaminari — face flushed, fingers tucked between his thighs.

“Would you please fuck me, Shinsou?”

I’m thinking of doing an NSFW flash thread where Kaminari gets hit with a sex quirk, and goes to Shinsou for help.

Any good?

OK.

We're doing this.

I'll be dropping it in small sections.

//...No way he just said that.//

Shinsou’s eyes went wide. “...E-excuse me?”

Squeezing his eyes shut, Kaminari let out a small whimper. “Sorry to be so forward, but...I was hit with a sex quirk while we were doing work study tonight. Midoriya got hit with it, too, but...I--”

“Why don’t you come in; it must be embarrassing to have to rehash this in the hallway.” Reaching his arm out, Shinsou took Kaminari by the shoulder and guided him into the room.

“Thank you.” He let out a heavy breath, then fell against the door as soon as Shinsou closed it behind him; his hands remained tucked between his upper thighs, and a bead of sweat rolled down his cheek.

//This looks brutal...//

Shinsou ran a comforting hand down the blond’s arm. “You were saying?”

“I don’t even remember wha--oh...M-Midoriya got hit with it, too...a-and Kirishima said we should just fuck each other, but...” he shook his head, “I don’t want to do that.”

Shinsou cocked his head. “Can’t you just...take care of it, yourself?”

Kaminari shook his head. “It won’t stop unless you have sex with another person, or ten hours have passed. And it’s like, no offense, but I don’t feel that way about Midoriya, you know?”

Lips coming apart, Shinsou’s breath hitched in his throat. “...But...that would imply you--”

Again, he squeezed his eyes shut, his face turning an even brighter shade of red. “I’ve had such a huge crush on you since our first year of high school, and if I’m going to have sex for the first time...it has to be with Shinsou!”

“Get the fuck out of here.”

Kaminari sighed. “I figured you’d have that reaction. I’m sor--”

Shinsou’s eyes widened. “N-n-n-n-no! I mean, I--” He grabbed the back of his neck, looking toward the floor.

“I’ve liked you since first year, too. I just figured there was no way you’d ever like me back, so I never said anything about it.”

“H-how could I /not/ like you?”

When Shinsou looked up at him, he was looking straight at him, just on the verge of offended. “You’re cool...you like awesome music...you’re pretty...you’re nice...even your quirk is cool!”

Shinsou’s heart thumped. “You think...my quirk is--is cool?”

Kaminari’s mouth dropped open. “WHO WOULDN’T?”

There was a full feeling in his chest, like he could burst or cry or jump out of a window -- he didn’t know what, but he was overwhelmingly compelled to do /something/.

“Tsk.” Kaminari dropped his head. “I’m sorry things’ve happened this way -- me, asking you to fuck me before even telling you how much I like you, but...I just couldn’t stop myself.”

Blink, blink. “...You’re /sure/ you’re real? Because I’ve fantasized about this more times than I care to admit to, and I'm kind of scared I've graduated to full-on hallucinations, at this point."

Despite himself, Kaminari let out a strained laugh. “I’m real. I promise.” He let out a little moan. “Real and /highly/ uncomfortable. In pain, even.” He looked up at him. “Shinsou please help me,” he asked in a cute, high-pitched tone.

Unable to stop himself, Shinsou breathed a little laugh. “I’ll help you, Kaminari.”

“OH THANK GOD!” The blond collapsed in on himself.

“On one condition.”

“NAME. IT.”

“We go on a date tomorrow -- a real one.”

Putting on the most genuine smile, even through his pain, Kaminari let out a little giggle and nodded. “I’d love that.”

Shinsou grinned; he knew he probably looked creepy, as usual, but he couldn’t help it.

The night went from quiet and lonely to purely elysian.

And it became even more so once Kaminari released his fingers from his thighs and shambled over to him.

“Careful.” Shinsou grabbed him by the biceps to steady him.

The blond looked up at him: dampened lips parted, the sheen of sweat over his face, the flush across his cheeks...it looked as though he had already done what Kaminari asked of him.

There was a tightness in his pants, already, and it got even tighter once Kaminari wove his fingers into Shinsou’s hair, stood on his toes, and pushed his lips against Shinsou’s.

The perfume of his skin and hair smelled like strawberries and freshly picked tomatoes, and he loved it; he’d never had the opportunity to get this close to him before, and had no clue how wonderful he smelled.

Kaminari made a subtle movement; his lips opened just a bit, and Shinsou took that as permission to run his tongue along the inside ledge of his upper lip.

A little whimper escaped the blond as he dragged his hands out of Shinsou’s hair, and onto his face, using his grip as leverage to deepen the kiss.

//Oh fuck, he’s good.
He’s wonderful.
He’s perfect.
He’s--//

A sweaty hand wrapped around Shinsou’s wrist; Kaminari flattened Shinsou’s hand against Kaminari’s stomach, then pushed it down until the fingertips slid just under his waistband.

//...putting my hand down his pants.
Thanks, God.//

That was enough to get the point across: Shinsou took his hand from Kaminari’s bicep, and used both to undo his pants, then fully slip under the waist band of dampened, sticky boxers to find a beautifully overwrought and painfully hard erection.

Twitching and hot to the touch, Kaminari moaned into Shinsou’s mouth the second his hand wrapped around his cock.

The kissing became ravenous and desperate, the blond’s hands going all over Shinsou’s body, like they didn’t know what to do with themselves; it only took about five pumps before--

“MMPHF!” Kaminari’s hands pushed on Shinsou’s face hard as he convulsed, taking noisy breaths through his nose, unwilling to relinquish Shinsou’s lips.

Unable to help himself, Shinsou opened one eye to peek at him; Kaminari’s eyes were rolled back in his head, one lid more open, one slightly closed, as the warm come pumped in a steady rhythm over Shinsou’s hand.

//Oh, fuck yes.
Bless you.
Bless you, Kaminari.//

Kaminari’s head fell back, breaking the kiss; his throat made beautiful movements as he gasped for air, and Shinsou couldn’t help but attack it.

“UH!” The blond’s hands stayed on Shinsou’s face, as Shinsou swirled his tongue over the Kaminari’s Adam’s apple. “I cah--I ca--”

“What’s that?” Shinsou asked against his neck.

“I need more!” The blond practically sobbed. “It hurts, Shinsou, it’s hurts!”

He came up from Kaminari’s neck to look at him; there were tears streaming from his eyes, and he couldn’t stop himself from thumbing at them with his other hand. “Try to calm down, OK?”

“I can’t!”

“Shh...” Shinsou kissed him on the cheek, then on the forehead. “I’m going to take care of you.”

//...As soon as I can find something like lubricant.
Think, damn it! Thin--
Wait.
Hm.
That might work.//

As quickly as he could, Shinsou pulled Kaminari’s pants all the way down, and the sobbing blond’s shoulders fell heavily against the door as he tried to help by stepping out of them.

“You OK?”

“No-ho-ho!”

Shinsou gave him a sad smile. “I meant from that fall; did you hit your head?”

Sniffle. “I don’t kno-how!”

“Kaminari...” He stood back up, placed a hand on his cheek, then pushed his lips against his as he undid his pants, and slid them down his thighs.

He could feel the excessive pre-come trailing down his own cock, and was grateful for it, for a change; it might actually be helpful.

He wasn’t quite sure his idea would work, but it was worth a shot.

Once he took his hand from Kaminari’s face, he used it to gather Kaminari’s come from the back of his other hand with his fingertips, then coated the head of his cock with it. “Put your arms around my neck, Kaminari.”

The sobbing mess before him did as he was told, then looked at him and sniffled. “What now?”

Taking a step forward, Shinsou pushed the blond against the door. “Lift your knee.”

“Which knee?”

“How about your right one?”

Again, Kaminari obeyed, and Shinsou looped his arm under it, so that it rested in the crook of his elbow. Once he had a good hold on his own cock, he leaned forward, lifted Kaminari’s leg higher, and angled himself at his opening. “Tell me if it hurts too much and I’ll stop, OK?”

After another sniffle, Kaminari nodded; a bit of eagerness somehow made it back onto his face. “OK.”

Slowly, he began to push, eliciting a gasp from Kaminari; just the first third of the head had gone in, but it was extremely tight.

“Was that a happy noise or sad noise?”

“Happy.” Kaminari tried to smile at him, but his lips were quivering. “Keep going.”

As he pushed in a bit more, the head fully making it into his body, it suddenly struck him just what he was doing, and a wave of ungodly horniness tingled its way through him.

He looked over this beautiful boy: his slender hips, lithe, shapely legs, elegant arms...he was a stark contrast to himself, who’d bulked up considerably since the first year of high school, and grown at last a half of a foot taller than the blond.

Shinsou closed his eyes as he continued to push into Kaminari’s tight little ass, and all of the ways he could toss this perfect twink around the bedroom flashed under his eyelids.

//Calm down.
I’m sure we’ll get there.//

Though, once he’d gotten about one quarter of the way in, Kaminari pulled him in and hissed. “Keep going, keep going!”

He wrapped his free hand around the blond’s back. “I will, just--”

“Fuck it; I can’t wait anymore.” Kaminari pushed down on him, forcing Shinsou’s cock the rest of the way in. “OH...OH SHIT...!”

It was Shinsou’s turn to have his eyes roll back.

//Oh shit is right.//

The way Kaminari clamped down on his cock made him see stars; Kaminari was hot and unbelievably tight, conforming to every curve he had.

“A-are you...OK?” Shinsou managed on a stuttered breath.

“Stop asking me if I’m OK and nail me, already, would you?”

Biting his tongue so he didn’t say the words, ‘marry me’ out loud, Shinsou pushed Kaminari against the door a bit harder, slightly bent at the knee, then withdrew a bit; he then pushed back up, just seeing how the mechanics of the position worked.

“UH!” The blond yelped, then brought his head back so he could look Shinsou in the face. He was flushed and sweaty and as beautiful as ever.

“Hug me, again.” Shinsou panted. “If I look at your face, I’m only good for another two seconds.”

Giving him a breathless giggle, Kaminari pulled him close, once more.

Wrapping his fingers around the blond’s hip, and getting a better grip on his leg, Shinsou began to drive into him.

His thrusts were slow but deep, and he loved the way the door banged every time he took Kaminari to the hilt.

“Huh-ell...ye-hes!” Kaminari squeaked. “It’s so perfect...it’s so good...I want it harder, Shinsou...do it harder for me?”

//Don’t come don’t come don’t come don’t come don’t come...//

“Put your legs around me.”

Once Shinsou released the sexy leg he’d been holding, Kaminari hopped up and hooked those long legs at the ankle, up around his waist; he grabbed the underside of each of Kaminari’s thighs, and couldn’t believe how easy it was to hold him.

He was so light.
So cute.
So small.

//Golf outings, grandmothers, kittens, no, no, no, don’t come.//

After taking a second to ground himself, he adjusted his legs, and started plowing into Kaminari a bit harder, but a lot faster.

“Ah--hh--hh--hh--hh--HH!” With every up-thrust, Kaminari’s voice hitched. “Harder, harder, hard--AH!”

Shinsou obeyed, slamming up into him more. Admittedly, he was a bit scared to go all-out on him; the last thing he wanted to do was hurt him.

“Is that good?”

“It’s so good, Shinsou! It’s so good! Hn! But I want to ride you!”

“You do?”

He felt Kaminari nod. “Please, let me ride you, please!”

//I think I might believe in God now.//

“Whatever you want, little kitten.” Shinsou stood up straight, turned them around, then went over to the bed and sat down on it, getting himself as far back as he could.

Kaminari let go of him, unhooked his ankles, and got onto his knees. “I need...to get out...of these clothes.” He struggled out of his jacket.

“Yes, please.” Shinsou nodded.

There was a little giggle, as Kaminari ditched his jacket, tossing it behind him; he went to take the blue sunglasses off of his forehead, but--

“I’ll take those.” Shinsou snatched them from him.

“You stealing from me, bitch?” Kaminari grinned as he lifted the shirt off of himself.

"The opposite, actually." Shinsou put the glasses on Kaminari's face, properly. “Do you know how many times I’ve daydreamed of you riding me, only wearing these and that choker of yours?”

“No.” The breath was heaving in and out of him so hard; his chest rose and dropped with a jerking motion. “But I could probably take a stab at it now.”

Giving him a wink behind the blue lens, he leaned forward, centering himself on Shinsou’s chest, then drew upward, and sat back again. “Oh, fuck; this is /really/ fucking good...oh God!”

Shinsou nodded, eyes wide. “Yes. Yes, it really fucking is.”

He ran his shaky hands up Kaminari’s slender sides; it was difficult to believe that this adorable creature was taking his cock so hard that it rocked him each time he came down, but...seeing is believing.

Or, in his case, seeing is salivating.

Kaminari sat back more, lifting his arms up, only to bend at the elbows, his hands dropping behind his head, bouncing and grinding like a fucking expert on his cock.

Shinsou brought his hand to the top of Kaminari’s shoulder and thumbed at the choker, trying to find a focal point to fixate on so he didn’t come.

“You are, without a doubt, the cutest thing in this entire fucking world, Kaminari.”

The blond let out a breathy laugh that could’ve been composed by Beethoven. “You’re the hottest, then. And the kindest. The most understanding -- God, I can’t believe you’d just let me come in here out of nowhere and fuck you into the ground like this.”

“Have you /met/ yourself? You could step on me, and I’d thank you for it.”

He giggled. “Yeah, sure.”

“I’m serious. This is a damn privilege, so do whatever you want to me.”

Kaminari grinned at him. “Why don’t /you/ do whatever you want to /me/?”

Shinsou blinked at him. “Are you sure?”

Giving him a sweet giggle through a toothy grin, Kaminari nodded. “Mmhm.”

Shinsou came to a sit, grabbed Kaminari by the ass, stood up, turned around, and put him on his back.

“EEK!” Kaminari let out the cutest laugh, and it made Shinsou smile.

“I’ve been edging this entire time; you’ve got to stop being so cute.”

But the statement only made him laugh harder.

Letting out a playfully frustrated sigh, Shinsou threw Kaminari’s legs over his shoulders, taking hold of his thighs, and started driving into him.

“Oh /shit/, you’re so deep!” Long, elegant fingers took handfuls of Shinsou’s comforter; his head rolled back, eyes closed behind those sexy sunglasses, lips open ever so slightly.

“Too deep?” he breathed.

“No, it’s awesome! I love feeling your big cock go inside me as deep as it’ll go!”

“I’ve noticed you’re not crying anymore, so maybe you’re being honest.”

Kaminari giggled. “If your dick’s inside of me, I’m fine.” He lifted his head a bit. “So, don’t take it out until I come.”

//Why do you try me, God?
I’ve just come to know you.//

Shinsou plucked Kaminari’s right leg from his shoulder, then put it next to Kaminari’s left leg; he then wrapped his arms around the both of them, right after the knee, and stood up a bit straighter.

The new position dragged Kaminari up off of the bed a bit, so that only his upper back was still on the mattress, then started plowing him.

“AHH!” The scream that the blond let out was equal parts shocked, amused, and pleased. “You’re like a fucking sex wizard!”

Shinsou laughed, as he drove into him. “I just have a vivid imagination when it comes to you.”

“I’m kind of mad at you for not sharing it with me for the last two years! UH! GOD!”

“Yeah, let’s not make that mistake twice.” He put Kaminari’s right leg back onto his left shoulder, reached down, and pulled the blond up into his arms again, then pounded into him.

“Holy shit!” Kaminari winced a happy wince, holding Shinsou around the neck. “You’re hitting something good...I feel like...I could--” He closed his eyes. “AH!”

Come splattered all over Kaminari’s chest, and Shinsou sighed in relief.

“You want me to pull out?”

“Fuh-uh-uh-uck ih-hit!” Again, the poor thing couldn’t talk properly with how Shinsou was manhandling him.

Unable to keep himself from getting just a little rougher toward the end, Shinsou came, shoving himself in as deep as he could go, letting out a satisfied groan to harmonize with Kaminari’s screams.

He turned, slowly sat onto the bed, and tried to catch his breath, but Kaminari came in close, smothering him with a kiss. “You’re my hero.”

Shinsou smiled. “So are you.”

Kaminari giggled. “Let’s explore more of that imagination tomorrow -- you know...after our first date?”

Making a breathy laugh, Shinsou nodded. “Anything for you, Kitten.”

I can't believe that I'm actually about to say this for once, but...the end!

If you liked my live flash smut, and you wanna drop a tip, here's my Ko-Fi.

If not, hey, that's cool; your patronage, QRTs, and enjoyment means more to me than money ever will. http://ko-fi.com/TempeTot 

I did a silly little after-the-sex story, and I hope you like it!

This takes place the day after.

Kaminari kicked in the door. “I’M ENGAGED!”

Every girl in the common room and Aoyama bum-rushed him. “AHH!”

“I KNOW!”

“Wait...” Kirishima blinked. “What?” He looked at Sero, who shrugged.

“TO WHO?” Bakugou actually looked shocked for once in his life.

“Hitoshi Shinsou!” Kaminari gushed.

“AHH!” The girls all jumped on him, again, bouncing on their heels.

Todoroki shot Midoriya a look, and he gulped.

“He’s /so/ handsome!” Mina whined.

“And those /muscles/!” Hagakure squealed.

“He’s a catch!” Uraraka giggled.

“You haven’t even graduated high school yet, you dumb ass!” Sero put his hands in the air. “What the hell, Kaminari?”

“HEY!” Yaoyorozu pointed at him. “NOBODY ASKED YOU, BITCH!”

“But--”

“YOU SHUT THE HELL UP AND BE HAPPY FOR HIM!” Jirou gave him a look that could melt tape.

“What is with all of the /screaming/?” Iida came from around the corner. “I’ll have you know I am /trying/ to /read/. Not to mention the fact that it is /twelve thirty/ in the morning.”

“Kaminari’s engaged!” Mina announced happily.

“AHH!” team ShinKami screamed.

Iida looked as though he were still trying to process what he’d just heard. “To be married?”

Kaminari nodded.

“We’ll talk more about this tomorrow, but...no. No to all of that.” He turned around and left.

“I know where you sleep, bitch.” Uraraka glared in Iida’s direction.

“I didn’t even know you were dating.” Midoriya squeaked.

“Careful, Midoriya.” Tokoyami leaned over to him. “You might not be allowed to say that.”

Yaoyorozu glared at Midoriya. “Thin ice, mister.”

“See?”

Giggling, Kaminari patted Yaoyorozu on the shoulder. “It’s OK. We actually just started dating tonight.”

“WHAT?” Bakugou, Kirishima, and Sero asked.

“Yeah! Last night, I went over to his dorm, and told him I’ve liked him for two years; he told me he liked me, too, asked me on a date, and then he fucked the quirk out of me!”

Midoriya’s mouth hung open, and Todoroki cleared his throat.

“AW!” Kaminari's supporters swooned.

“And you got engaged at what point?” Kirishima turned more towards him.

“Before our date tonight.” Kaminari giggled. “I showed up, gave him a limited edition ‘Soft Cell’ album to apologize for last night, and he dropped to his knee right there and asked me to marry him!”

“And you said--”

“YES!”

“AHH!” The girls and Aoyama screamed.

Todoroki crossed his arms and looked away from Midoriya, who squirmed, then looked at Kaminari. “But what about high school?”

“Midoriya,” Kaminari snickered, “we’re adults, and graduating from high school in three weeks. Don’t be silly.”

“You don’t think this’s all a bit...” Kirishima shrugged, “fast?”

“He doesn’t need your approval, you whore!” Uraraka yelled.

“It’s OK, Uraraka.” Kaminari shook his head, all smiles. “He hasn’t met the right one yet.”

Bakugou raised an eyebrow.

“When you know,” Kaminari sighed, “you know. You know?” He giggled. “I just love him so much! And I know he loves me, too!”

“AW!” The girls swooned.

“HUH-UH!” Todoroki cleared his throat very loudly before crossing his legs, and Midoriya was sweating bullets.

“Did you even /go/ on this ‘date’ tonight?” Bakugou asked, clearly disapproving.

“Yeah!” Kaminari blushed. “You know...afterwards.” He covered his face and giggled.

“I’m calling it:” Bakugou pointed at Kaminari, but looked at his other friends, “he’s full of shit.”

The door to the common room opened, and Shinsou walked through; his presence elicited a loud collective gasp and some squeaks, and he gave the group a raised eyebrow.

“Uh.” Shinsou looked around. “Hi.”

Kaminari took a few steps forward, smoothing his hair and grinning like an idiot. “Hey.”

And just like that, Shinsou lit up. “Hello, Future Husband.” He slid his hands around Kaminari’s lower back, pulling him in, pressing a kiss to his neck; grabbing him by the biceps, Kaminari dropped his head back and giggled.

“Oh my God,” Sero said.

“It’s real.” Kirishima stared in disbelief.

Bakugou threw his hands up and shook his head. "At least I didn't put money on it."

“Not to look a gift horse in the mouth, but...how am I so lucky to be seeing you again so soon?” Kaminari ran his hands up to Shinsou’s shoulders.

“You mean, other than me just wanting to see the most beautiful creature in the world?” Shinsou gave him a look that could unzip one’s pants.

“Yo--” Kaminari giggled. “Hitoshi...!”

After observing him for another second or two, Shinsou sighed, then reached into his back pocket; when his hand came back, he was holding Kaminari’s choker between two fingers, staring into his eyes the entire time. “You forgot this.”

“Oops.” He gave Shinsou a mischievous grin. “I guess that makes me a naughty kitten.”

Shinsou nodded. “/Very/ naughty.”

“And what do you do...with naughty kittens?” Kaminari bit the side of his lower lip.

“I make them climb the curtains,” Shinsou grumbled, sliding his hand onto Kaminari’s ass.

“Do you...play with them?”

“Until they pass out.”

“Doesn’t that take a while? You know kittens; they always want to be,” Kaminari pressed his groin against Shinsou’s, “batting something around.”

“Depends on the kitten.”

“This one, though, is /especially/ energetic, so...it might take a while.”

“I have insomnia; it doesn’t matter to me.”

Kaminari let out a hot breath, then grabbed him by the hand and practically ran toward the stairs. “Let me show you my curtains.”

Kaminari and Shinsou disappeared up the stairs.

“I think I just came.” Mina wiped the sweat off of her brow.

“I think I’m pregnant.” Yaoyorozu fanned herself.

“Let’s go listen at their door!” Aoyama jumped in the air.

“YEAH!” The girls cheered, then sneaked away.

“Well,” Kirishima got up and stretched, “I guess I’m with Bakugou tonight.”

Sero nodded. “Me, too.”

Bakugou scowled. “The fuck out of here!”

“Our rooms are on either side of Kaminari’s; we’re bunking with you, Bakugou.” Kirishima eyed him.

“Deal with it.” Sero got up, too.

“Not if I lock you both out.” Bakugou got up and ran for the stairs.

“HEY!” Kirishima took off, with Sero running off after them.

“I’m going to bed, too.” Tokoyami got up. “A pleasant slumber to you both.”

The only ones left were Midoriya and Todoroki.

“Maybe...” Midoriya said in a small voice, “it’s...not...too soon, after all?”

“Hm.” Todoroki went quiet.

“So...are we engaged, then?”

“We’d better be.” Todoroki still wouldn’t look at him. “We’ve only been together for almost /three years/, you douche.”

Midoriya made a little smile. “When do you want the ceremony?”

Todoroki rolled his eyes, still looking bitchy. “December, I guess.”

“Because you’re my snow prince.” Midoriya grinned.

Finally, Todoroki smiled and looked at him. “And you’re my little Christmas tree.”

Midoriya giggled and gave him a kiss on the cheek.

The end!
