After that, it was like the floodgates opened.
Aki fucked Denji everywhere. On every surface of the apartment. Bent over the counter in the kitchen. Pulled onto his lap while he sits on the balcony drinking his coffee and smoking his morning cigarette. Wherever he had the chance outside of the apartment. Pulled hastily into an empty room quickly before or after Makima had called them in for a briefing, then pushed up against a wall. Quick and dirty with his pants around his ankles and his cum left on the floor. Bent over behind a dumpster down the same alley where he'd first told Denji to quit the team.
Everywhere and anywhere he could, he did.
Denji didn’t know that you could have too much sex. Sure, he’d heard the off remark here and there but he thought whoever was saying it was just being a little bitch.
He understands it now though.
Apparently when he told Aki not to worry because “he’ll heal” he took that as a challenge. He’d plow Denji way past overstimulation straight into unconsciousness and when he’d come to, Aki would still be pounding him.
The bastard is insatiable.
Tonight they’re laying side by side on Aki’s bed, Denji’s leg thrown over Aki’s hip as Aki casually fucks into him. It’s something Aki calls a “spoon” which, no it’s not. Denji knows what spoons are and it’s not people laying on their sides. Aki likes this position because they can lay together for hours while Aki casually thrusts up into him.
It’s humid in the room, they’re both sticky with sweat. The bed covers smell like them: cigarettes and cedar shampoo. The sheets stick to Denji’s skin uncomfortably but he’s strangely content. He likes to use Aki’s arm as a pillow in this position. He can really focus on the detail of his strangely mesmerizing hands.
His elegant fingers.
The veins throbbing right under the surface of the delicate skin on his knuckles.
He traces the green and purple webs along his palms. The light scars, long since healed.
"You're so tight," Aki groans, kissing and nipping along his shoulder. "Your hole feels so good"
“That’s cuz I had to heal this morning,” he grumbles. He may bitch and moan about how much Aki fucks him but honestly, Denji doesn’t mind it. If he’s being even more honest, he downright fucking loves it. But he won’t tell Aki that.
“S’at so?” He says on a deep inhale like he’s reaching enlightenment one breath at a time.
“Ye-eaaahh!” His voice spasms into a gasp then fades into a moan as Aki wrenches Denji’s legs back towards his head and starts slamming his hips up. It’s electrifying. All of his nerve endings are frayed in the best way and his body tingles.
Again and again, he pounds away at Denji’s tender asshole. It’s making his brain feel like mush, more so than usual.
Shit, this feels so fucking good.
In way less time than Denji would like to admit, Aki had conditioned him to come hands-free. On the one hand, it's way more intense of an orgasm and he can come for like, forever. On the other hand, he basically never touches his dick anymore which is...really strange considering he's spent the better part of sixteen years jerking it into oblivion.
Without warning, Aki slides out and flips them so Denji is on his belly and Aki is behind him, between his legs. He pushes Denji’s cheeks apart just long enough to spit directly onto his hole before driving himself back in all at once. Denji writhes, clawing at the sheets as the air is punched from his lungs. Slender fingers slide up his arms until they tangle with his own. All he can focus on are the airy "ah ah ahs" leaving his throat and every rigid contour of Aki's cock as it carves its way through him.
Everything is in stereoscopic proportions; the weight of Aki laying on top of him, his hot breath on the back of Denji's neck, his hands in a tight grip with Denji’s own, and his heavy balls that slap against Denji’s with every thrust. It’s all more intense than it should be and Denji can feel his orgasm approaching quickly.
The rocking of their bodies pressing his erection into the bed is more than enough friction and he studders and quivers as he comes, so intense he sees stars.
Not long after-could be a couple of thrusts or a couple of hours, Denji’s brain is too fuzzy to think clearly-he can feel Aki getting close. His rhythm getting more and more sloppy until he unloads inside and Denji can feel it. Each jet splashing against his insides as Aki’s cock spasms inside of him. He’s not sure if he’ll ever get used to the feeling.
Denji feels wrung out like a juice box sucked dry. He’s tired and thirsty and laying in his own cum but even still, he begins drifting off. The weight on his back is oddly comforting, an Aki blanket.
Sometimes, Aki stays inside of him afterward. Pets along his sweaty worn-out body and tells him how good he is. Tonight is one of those times.
Aki’s fingers are still laced in his own and he kisses along Denji’s shoulder, his neck. Noses along the shell of his ear. Wherever he can reach without disturbing their position.
It feels far more intimate than the cock up his ass which baffles Denji even when he’s not in the foggy afterglow of a good orgasm. He hums his approval, the only thing he has energy for, at the soft treatment.
Aki exhales lowly, grinding his hips into Denji's and he feels him getting hard again.
“A-again?” he asks, dumbly.
“Again,” Aki reiterates, rocking into him as he sucks the back of Denji’s neck where he’s most sensitive, eliciting a soft moan.
He brings one of his hands under their bodies to play with a nipple and just like that, Denji’s hard again. He’s still sensitive though and not sure he can come again so soon.
“Can’t-!” he manages to rasp.
“You can,” Aki says, sounding completely unfazed like he’s doing dishes and not taking Denji apart completely and thoroughly until he’s a melted puddle of satisfaction.
He pinches and pulls at the little bud and Denji jolts and bucks, taking Aki deeper each time he does. Making Aki groan at how good he feels.
“Aki! It’s too much…I can’t,” he’s drooling now, eyes leaking. His face is broken or something cause it just won’t stop.
“One more,” he says pulling on Denji’s nipple in time with the thrusts aimed directly at the devil’s prostate. “Give me one more, you can do it.”
"I can't," he cries, wrenching his head back like that's going to do literally anything.
"Denji," Aki kisses the side of his ear, takes the lobe between his teeth. "Come for me."
He does.
With a whine and a choked sob, Denji comes again and collapses into the sweaty sheets.
They fucked for hours, fucked until Denji’s ass went numb. Until he’d fallen asleep and woke up, completely worn out, with Aki lightly snoring on top of him; he'd also fallen asleep, only with his softening dick still planted deep inside.
Denji wriggles to get out from under him so he can go clean up but somehow Aki gets hard again in his sleep and dry fucks Denji. Well, not completely dry. He still had a couple of loads up his ass. How has Aki's dick not fallen off yet?
It wasn’t the most comfortable for sure but Denji just let him sleep hump his ass until warm cum dribbled into him again. He's honestly surprised Aki still had any left.
After he’s cleaned himself up and changed the covers out for ones not covered in their bodily fluids, Denji crawls into bed next to Aki. He grabs one of his hands and runs his serrated teeth along the calloused pads of Aki’s fingers, slicing the tip and letting a few fat drops of blood slide down his tongue.
Immediately he feels it. His body goes from feeling abused and sore to feeling nothing at all. Perfectly normal. Well, as normal as normal is for Denji anyway.
It’s an unspoken agreement they have. Aki can wreck him and tear him apart as long as he puts him back together. It’s a bond of trust Denji never could have possibly imagined having, let alone with another guy.
He lays awake in bed even as Aki sleeps peacefully next to him. The most peaceful Denji ever sees him actually. His frown lines are all smoothed out. His dark hair splayed across his pillow. He sleeps on his side and only occasionally moves to stick his foot outside of the covers. He looks the exact opposite of how he does when he’s awake. Everything polished and concealed; not a hair out of place. When he’s sleeping he’s…open, vulnerable.
Denji traces along the shell of his ear as he tucks a stray hair behind it.
What was he doing?
Having sex with Aki daily. He almost never sleeps in his own bed anymore. They’re always together. Are…are he and Aki dating?
They’re not though right?
They’ve never kissed. Denji won’t allow it. It’s his hard line. He’s not gay if they don’t kiss. His first kiss was terrible but he can still save all the others for Makima.
Right?
Isn’t that what he wants?
He gazes at Aki and the gentle rising and falling of his chest and suddenly he’s not so sure.
The question Aki had asked him before echoes around in his head.
“What do you think we are?”
“I have you.”
He snuggles in close to him and Aki shifts in his sleep so he’s facing Denji. He’s not sure what comes over him. Maybe just pure curiosity.
He presses his lips against Aki’s chin, gently so as not to wake him. It just feels like skin. He doesn’t feel any different. Doesn’t feel like he's changed.
He does it again, this time closer to Aki’s lips. Again, nothing.
Okay, this time…the true test, the real thing.
He scrunches his eyes tightly shut and brushes his lips every so faintly against Aki’s.
Nothing.
No sounding alarm saying he’s lost the remainder of his straight-ness. No gay police barging in, telling him he’s fully gay now. Nothing. It’s... anticlimactic.
Huh.
So he does it again, this time more deliberately and he keeps his eyes open. Aki’s lips are soft if a bit slightly chapped. Soft the same way Himeno-senpai’s lips were. He closes his eyes and focuses on the feeling of it as he presses closer.
Feels just like that one time before everything went to shit. Or, more accurately, vomit.
The lips move against his the same way, and the tongue that slides along his teeth makes his insides feel like jelly.
Wait.
He opens his eyes and pulls back to see blue eyes watching him.
“You kissed me,” he reaches out to touch Denji’s face. “I thought you didn’t want to.”
“You do though,” Denji looks away, at the collar bones peeking out from under the blankets. “I…I wanted to try…” he glances at Aki’s lips before eventually looking back to his eyes, just to see what kind of expression he’s making.
“Thank you,” he smiles and leans in.
This time, unlike every time previous, Denji lets him. They kiss and it’s amazing, like everything Aki does. He should have done this much sooner because it's lighting up nerve endings he didn't even know he had. It makes him feel light and bubbly and strangely...happy?
“Denji,” Aki breaks from his lips to kiss up his jaw and his neck and he can’t stop the whine that seeps out of his mouth. “Again.”
Denji nods and sighs, melting into the feeling. “Again.”
