Denki lay on the coach in the common room, an unusually quiet day for the
dorms. He had his eyes glued to a stupid reality show on television- so void of
life Bakugou wasn't even sure if he was awake. Could that fuck sleep with his
eyes open?

"Hey Sparky, open up." Bakugou snapped. He knelt in front of him and Denki
absentmindedly lolled his mouth open.

"You're fucking disgusting, you know that?...Hey!" Bakugou popped his phone
into his mouth, Denki jumped, snapping his mouth closed. A puff of smoke
emitted from around his mouth.

"Jus-shh sho you -"

Bakugou snatched the phone. "Seriously, Pikachu, you just gonna open your mouth
for anything?"

He was wiping his phone off on the front of his pants, unaware of the heat
plastered across Denki's face. Denki was used to getting requests such as
charging people's cell phones. The electricity he emitted was conducted through
his saliva and would work on any charge port- have to admit it comes in handy.

"Well..not for just anything.. I guess." He squirmed on the couch, pushing up
into a sitting position. "I can still charge that for you if you want?" Denki
held his hand up, sucking his bottom lip into his mouth.

"Ya, whatever." Bakugou handed over the phone and took a seat in the corner
opposite Denki, couch sagging beneath their combined weight.

"Ish pree-y han-y" Denki is talking with his mouth around Bakugou's phone and
that really annoys him for some reason. He represses his anger with an audible
cough- this idiot was doing him a favor after all.

"Don't talk with that in your mouth, it's fuckin gross."

He tried not to look at Denki, that fucker was smiling, and a little bit of
drool was starting to seep out of the corner of his mouth. Bakugou frowned, his
heart started beating just a little bit faster. What the fuck? He shifted his
weight so he could bring his leg up on the couch- why the fuck was his dick
twitching at that idiot drooling. Bakugou had wondered about Denki's mouth
before, he liked power after all. The thought of pressing his mouth to that
electric outlet, what would that feel like? He opened his mouth enough to allow
room for his breathing to steady.

"Just...just give me my phone back, it's fine." Bakugou wanted to get out of
there.

Denki frowned, letting the phone fall from his mouth into his lap. "It's not
even done, yet."

"Ya..it- I said it's fine." Why didn't that idiot just hand him his phone?
Bakugou reached over to his lap, but his hand paused a little too long, his
face screwed up as he looked at Denki's mouth.

"Y'ok man?" Denki was scrunching his nose up, Bakugou closer to him than he
usually got- unless it was to punch him.

Bakugou had to focus all his energy on swallowing the slug in his throat. He
knew his mouth was open, panting, looking at that fucker. Maybe..just..

His hand reached up, and he placed the tips of his fingers on Denki's lips. He
didn't jerk away like Bakugou was expecting, both of them sitting at an awkward
distance, locked on each other like a hunter and prey. Bakugou saw the slight
fear tinged in his eyes- thought it was good he was scared, maybe he'd be too
afraid to tell anyone about this later. Slowly, he slid one finger into Denki's
mouth, hooking it into his cheek.

Denki moaned.

Bakugou's eyes flew open, his finger retreated. Maybe he was a little scared,
too.. but.. that was hot.

Denki had that same damn look on his face. His eyes were ready to run, but his
breathing was ragged and needy.

"Um.. why did yo-"

"Don't! Talk about it."

Denki yelped, his face was burning.

"Just.. just open your mouth, fucker." If he was going to do this, it was going
to be his way.

Bakugou let his finger run the length of the inside of Denki's bottom lip, he
saw a familiar look on his face- his eyes half closed, sighing against the
touch. The fucker liked it.

"Oral fixation?" Bakugou's hand relaxed into his mouth, pushing a second finger
in, he couldn't help it. "Go ahead, suck on them."

Denki's lips closed and heat flooded through Bakugou's body; when Denki made a
"hmm" sound and let his eyes roll back, laying his head against the couch,
Bakugou became painfully aware of the tent in his pants. He pulled his fingers
out to the first knuckle, then slid them back in, feeling them lightly scrape
against teeth and slick across Denki's tongue. He couldn't believe how hot he
thought this was. Denki rolled his tongue around Bakugou's fingers and he
moaned imagining it was his cock- it seriously needed some attention right now,
but he'd take care of that later.

"You like that? You like sucking on my fingers, Sparky?" He was answered by
Denki opening his mouth to put on a show. His tongue teased out of his mouth,
starting from the bottom of Bakugou's palm, he slowly licked up until he was at
the tip of his middle finger, then he took them back in his mouth, devouring
them to the knuckles.

"Shit, you do like my fingers fucking your mouth, ya?" He put a third finger in
his mouth, Denki raised his eyebrows, but kept sucking. Bakugou needed some
form of relief now, so he twisted around and lowered himself on top of Denki's
lap, his knees pressed to the back of the couch.

"Fuck." Bakugou sucked in a ragged breath as he ground his hips as hard as he
could manage. He was met with a thrust from Denki. Bakugou gripped the back of
the couch with his free hand and rolled, starting from his chest and ending
with his cock. Denki laced his fingers through Bakugou's hair- he was using him
as leverage for his hips, desperate for the relief coming from grinding their
erections together. Bakugou let his fingers pull in and out, making lewd
sucking and squelching noises, and damn it was really hot.

"Suck like you're on my dick, fuck." His eyes were screwed shut, imagining that
mouth closed around his cock, tongue lapping at his head before finding his
slit and dipping in to taste his pre come. He had forgotten about Denki, about
where they were. He was savagely rutting against the couch, and he knew the
gasps coming from his mouth must sound wrecked.

"Oh ya, suck me.. jesus, fuck." Bakugou slammed down onto Denki's lap, feeling
warmth spread over his abdomen on the inside of his pants.

After the high of his orgasm, he felt embarrassment flood through his body. His
hand was still in Denki's mouth. Shit. He shouldn't have gotten so carried
away.

With a little more force than necessary, he removed his hand and pushed off the
couch. He couldn't bring himself to look at Denki, so he swiped for his phone
and made for the stairs.

He hoped that fucker kept quiet.
End Notes
     Actual Prompt:
     So like i was just hoping for like..someone asking kaminari to charge
     their phone and suddendly being really fascinated by his mouth. And
     what ensues is the person just the person pulling out the charger and
     instead putting their fingers in. And turns out, kaminaris mouth is
     quite the erogenous zone for him. Bonus points for flustered denki
     trying to hide his kink (and boner ) And dirty or sweet talk from the
     other person (maybe seto or bakugou ?)
