I have had no thoughts since I found out about this. Bakugou's sweat is nitroglycerin, and that chemical in of itself smells and tastes like caramel. (Although the taste also burns a little bit) and I have had nothing but horny thoughts since so like-
#kiribaku incoming

Quick cw: mentions of overdose, ig drugged sex but it's completely consensual, hair pulling, biting, light choking/breath play, maybe more (I'll try and tag anything serious using )

(Both are aged up and pro heros in this)

Kirishima and Bakugou could have been dating for a while at this point and maybe Kirishima has felt some of the effects of Bakugou's nitroglycerin because it can be absorbed through skin.

And maybe Bakugou knows the effect nitroglycerin has on other people.

Such as making people feel calm and relaxed, but it can also drop blood pressure which can be a problem. So, Bakugou avoids letting Kirishima bite or taste him as much as possible.

Dodging the questions, avoiding getting too intimate, trying to explain to Kiri the risks of him+

Od-ing on it but getting nowhere as Kirishima is dead set on tasting his boyfriend at some point.

And as much as Bakugou denies that he worries about Kirishima or denies that he doesn't want the other to bite him. He does worry, and he does want Kirishima to bite him so fkn bad.

So sue him if when he's cuddling with Kirishima he starts to bare his neck to the other boy, hiding it as if he's stretching or something else. He wants Kiri to just break and bite him anyway, but despite Kirishima being excitable at times, he respects that Bakugou told him no.

So that goes nowhere, and in turn Bakugou gets flustered. He doesn't want to ask Kirishima after so vehemently telling him no.

So he tries something else.

When Kirishima is up one morning in their shared home working on breakfast, Bakugou sneaks up behind him.

Wrapping the slightly shorter boy in a back hug, Kirishima smiles.

"Morning sleepyhead," He says cheerfully. "How are you-"

"Shut up," Bakugou mumbles just before biting Kirishima at the juncture between his shoulder and his neck.

Kirishima accidentally lets out a moan before blushing deeply. "K-Katsuki, what... What are you-"

Bakugou interrupts him again with another bite and while Kirishima manages to hold back his noises, he reaches to turn off the stove.

"I want you to bite me idiot," Bakugou growls, nose pressed up against Kirishima's neck. "I've been trying to get you to for a week now."

"Why didn't you- just ask me?"

"Because I told you no so firmly before," He mumbles, closing his eyes for a moment.

Neither of them are wearing shirts and Bakugou is enjoying the skin to skin contact as he usually does, only, this time he doesn't pull away when he's starting to get sweaty.

"Bakubabe, you should know I won't judge you for that," Kirishima says.

He turns around in Bakugou's hold and rests his arms on the others shoulders with an understanding smile.

"I know it's just- tch, embarrassing," Bakugou mumbles, not looking into Kirishima's eyes. "Are you going to bite me or what?"

"I wasn't expecting to get some action this early in the morning," Kirishima whispers huskily as he leans towards the others ear, "but don't catch me complaining if I get to have my dessert before my breakfast~"

"Sh-Shut up b-ba- ah~" Bakugou can't help but moan.

Kirishima had grabbed Bakugou's hair and forcefully pulled his head to the side before sinking his teeth into Bakugou's shoulder. He's careful not to break the skin, but he moans at the taste of his boyfriend. It's exactly like sweet caramel but it bites with a bit of a burn+

just like his Bakugou. It fits him perfectly.

"Dumbass, you have to warn me of that," Bakugou whispers before whining when Kirishima pulls away, scraping his teeth against the other's skin as he goes.

"Mmm," Kirishima hums against the others skin, feeling his muscles relaxing+

already. "What if I don't."

"You can't just- a-ah~ Stop doing it so suddenly," Bakugou grips onto Kirishima's hips and the other chuckles before growling a little, still biting onto the other, this time on the neck.

"You taste just as good as I imagined you," Kirishima purrs. Bakugou always smells so good, always so enticing, so now that Kirishima can finally taste him he wants to drown in it. "But we've got to go go the bedroom or I'll take you on this fucking counter," Kiri growls.

"Don't care," Bakugou mumbles before realizing that because of his sweat Kirishima could get dizzy very easily. "N-Nevermind bed," Bakugou says just as Kirishima was about to pick him up.

"Fine with me," Kirishima says, picking up Bakugou and carrying him anyway.

Both of them can carry each other, but Bakugou always feels his stomach flip when he's easily carried like this. But of course, he'd never admit it, too embarrassed to tell Kirishima outright. Or anyone for that matter.

He can't risk ruining his reputation as a pro hero.

Can he?

When he's laid onto the bed Kirishima is immediately biting his skin again as the blonde hero moans. Bakugou has always been shy of his moans, and even now his entire face and part of his chest is flushed red. It only serves to raise his body temperature.

This, in turn, makes him sweat and only makes Kirishima want more of his boyfriend.

"I'm addicted to your taste pebble," He whispers and Bakugou huffs.

"Don't call me that, d-dumbass."

"Whatever you wish Bakubabe," Kirishima purrs before chuckling and leaning up to kiss him.

Bakugou hums happily, wrapping his arms around his boyfriend to pull him closer. He growls into the kiss when Kirishima's hands start roaming lower, just barely touching the waistband of his sleep pants.

"Touch me," Bakugou growls and Kiri just laughs at him.

Bakugou growls again before Kirishima finally speaks. "Ask me nicely big boy," He says and Bakugou just glares at him.

"I said, touch me."

"And I said ask nicely. You're not the one that makes the rules," Kirishima says with a smirk.

Running out of tweets I can have in this thread so I hoped you guys liked this preview. Kirishima is a power bottom by the way. I'm going to get into the more spicy stuff soon. For now feel free to tell me what you thought here: https://curiouscat.qa/sleepy_kuroo_
