That night, the night Atsumu cut his hand, was the night their lives began to intertwine in ways they never could have anticipated.
Sakusa seemed to appear out of nowhere, as if he smelled it (later on, Atsumu found out he did) from inside his apartment.
His eyes widened as he saw the droplets of blood welling up from Atsumu's wound. It was deeper than he expected as it trickled down his hand.
"I can help, if you'd like," Sakusa offered. Atsumu stared at him, dumbfounded. What was his cute neighbor he'd been eyeing for a while even doing here? But despite all this, Atsumu just nodded and said, "Sure, how?"
Without a second thought, Sakusa grabbed his wrist and pulled it toward his face. He leaned in, his lips brushing against Atsumu's hand. It was a gentle, almost reverent touch that took Atsumu by surprise.
Atsumu felt his hand tingle, and as Sakusa swiped his tongue over the palm of his hand, he involuntarily moaned.
Sakusa moved away, blood smeared around the corners of his mouth. The wound was completely gone.
"Wh-"
"I need some help and I assume I owe you an explanation," Sakusa cut him off. "Let's go to my place."
"Sure."
And that's how Atsumu learned the secret of Sakusa Kiyoomi, how he had been turned into a vampire a couple of months ago and how badly he had been aching to feed on Atsumu, how nice he smelled and how good he tasted.
He survived on animal blood mainly, and even that made him queasy.
Now, though, Sakusa was playing with the baby hairs at the nape of Atsumu's neck, twirling them around his fingers. Atsumu's hands were resting on Sakusa's waist, squeezing him softly.
“Are you sure you’re feeling okay? I’m not feeding too often, am I?” Sakusa asked softly.
Atsumu threw his head back.
“Healthy as ever.” He gave the man on his lap a broad smile.
“Why do you even let me do this?”
"We both know I was already staring at you ‘fore all this."
"You flatter me."
"It's the truth," Atsumu smiled at him. He was always one to wear his heart on his sleeve, and he wouldn't stop now. Especially not when the pretty boy of his dreams was sitting on his lap, mentally preparing for biting him again.
"Y'know, ya could bite my neck this time…"
Sakusa's eyes widened ever so slightly. "Are you sure?"
Atsumu nodded, trying to hide his excitement. "I think I'd really like it."
"Alright," Sakusa rolled his eyes, letting them wander before he closed them. "Sorry this keeps taking so long."
"I've got all the time in the world for you."
"Enough to be good for me once more?" Sakusa smiled innocently at him before moving his hand to Atsumu's cheek. He slightly pushed his head to the side, baring his neck for the young vampire to see.
Atsumu let out a shaky breath as the words shot straight to his dick. Opening his mouth to say something, anything, Sakusa subtly slips his thumb in.
“Ssssssh…” He brings out as he moves in to kiss Atsumu’s neck softly. Atsumu hums appreciatively around his thumb, making Sakusa's kisses falter ever so slightly.
The graze of teeth and then something sharp - also teeth, Atsumu quickly realizes - signal him to relax, so he does. Of all things, he didn’t expect to moan this loud from being bitten, no, being fed on like this for the first time.
Sakusa chuckles softly as he drinks.
Atsumu moves his hand up Sakusa's head, twisting his fingers into his hair as he keeps him there. After a bit, Atsumu feels the fangs retract and Sakusa starts lapping at his neck.
“Fuck…” Atsumu breathes out, panting slightly.
There’s the usual slight faintness, nothing new and nothing heavier than normal. Sakusa sits back up, straightening his back.
“We could.”
Atsumu blinks at him.
“What?”
"Fuck."
Atsumu’s brain short-circuits right there and then. “What?”
“I’ve been eyeing you too,” Sakusa says with a trace of mockery lining his voice. “Would you want to?”
Atsumu doesn’t need to think twice about his answer. “Yes.”
Without further hesitation, Sakusa’s lips are on his. He’s so / there/ and his hands sneak their way into Atsumu’s hair, pulling roughly.
Atsumu gasps into his mouth, which Sakusa takes as a good opportunity to slip his tongue in.
“‘Omi…” Atsumu manages to moan in between kisses, causing him to slow down. He breaks away, allowing Atsumu to take off his shirt.
Sakusa leans back slightly, obviously enjoying the view with a small smirk.
Atsumu pulls at the hem of his shirt next, signaling he wants it off and he wants it off now.
Sakusa obliges, pulling it over his head and leaving Atsumu as the one staring until Sakusa decides it's enough.
Atsumu’s neck is still a bit sensitive from the bite, something Sakusa seems to know and use to his advantage. Atsumu lets out a low moan as his lips connect to the soft skin.
Grazing his teeth over Atsumu’s neck, Sakusa turns him into a shaking mess in no time.
Clawing at Sakusa’s skin, leaving marks if only he could. Knowing he’ll heal immediately, Atsumu allows himself to be a little rougher, digging his nails into his shoulders as Sakusa bites his ear.
“Can ya fuck me already,” he pants out, smiling as Sakusa trails kisses from his ear to his mouth before giving him a chaste kiss.
“Someone’s eager.” He chuckles as he gets off his lap. He sinks through his knees, opening Atsumu’s pants in a smooth motion.
Atsumu isn’t embarrassed that he’s already as good as hard, moaning as Sakusa’s fingers brush against his underwear. “Do you have lube?”
“The nightstand,” Atsumu manages to bring out, “Second drawer.”
Sakusa moves from between his legs and Atsumu takes the chance to get out of his pants.
He registers the chuckle from Sakusa as he grabs the lube, but his chance to ask is soon taken by Sakusa’s lips kissing his own.
“Get on all fours.” Sakusa orders, sending a shiver down Atsumu’s spine.
He does just that, earning a slap on the ass. “Tell me if you don’t want me to do something, okay?” He moves in closer, grabbing it firmly. “Or if you do.”
Atsumu looks back, eyes blown wide in lust. “Make sure I can’t walk tomorrow.”
“Understood.” Sakusa nods, squeezing roughly.
He pulls Atsumu’s underwear down, making him hiss as his dick comes into contact with the cold air.
A lubed up finger is pressed against his asshole, slowly circling around and into it. Atsumu moans loudly.
After a second, Sakusa adds a second finger and starts fingering him open. At this point, Atsumu bites his lip, not wanting to disturb their neighbors.
Sakusa adds a third finger, making Atsumu almost fall over as he lets out an escaped moan.
“I want to hear you,” Sakusa says as he bends over him. “Please.”
“Fuck,” Atsumu half-moans. “Fuck yer hot.”
“Look who’s talking.” Sakusa laughs, digging his fingers into Atsumu’s prostate.
“Please,” Atsumu lets out, not caring about how whiney he sounds. “Fuck me, ‘Omi.”
Sakusa just chuckles, removing his fingers.
Atsumu hears the cap of his lube crack open loudly. “Ready?”
“Gods, please.” Atsumu begs.
Sakusa doesn’t need any more motivation it seems, as he pushes into Atsumu, who in turn loses balance in his arms, falling face first into the bed.
Sakusa twists his fingers into his hair again, keeping him there as he pushes in.
“You’re being so good for me,” Sakusa whispers, causing Atsumu to moan loudly.
Slowly grinding into him, letting him adjust, Sakusa pulls on his hair roughly. Atsumu lifts his head, looking back at him. "More."
What more can Sakusa do than oblige?
He pushes in fully, bottoming out in the most delicious way possible. As if feeding on Atsumu wasn’t good enough, he thinks to himself, now he gets to enjoy him like this too. Atsumu is moaning loudly, short breaths escaping his lips.
Sakusa grabs his shoulder, pulling him up so he’s on his knees only. His dick shifts deeper inside, causing Atsumu to moan loudly on the way up. “So good.” He whispers in Atsumu’s ear, twisting one of his nipples playfully.
He feels his teeth grow slightly, smiling to himself. He lets the fangs roam over Atsumu’s neck and shoulder, pampering kisses and nibbles along the way.
“Y’know, using-” Atsumu brings out, “using yer fangs is cheatin’.”
“How so?” Sakusa whispers calmly, thrusting upwards with his words to drive a point. “I’m curious as to how far your bite kink goes.”
“Fucking bite me then.” Atsumu moans out.
Sakusa doesn’t need to be told twice, sinking his teeth into Atsumu’s perfect neck. Atsumu’s loudest moan yet along with the taste of his blood hitting his lips sends shivers down his spine.
He quickly licks the spot, still properly fucking into him. Atsumu’s moans are loud and uncontrolled, just the way Sakusa likes it.
“‘m close.” Atsumu breathes out, hands clawing at Sakusa behind him. “Don’t stop.”
Sakusa chuckles. “I wouldn’t dare.” He somehow manages to say as if he isn’t approaching his own orgasm at a rapid speed.
His hips start snapping a bit more, losing rhythm.
Atsumu’s moans turn a bit more high pitched, a bit more whiny, and Sakusa feels him almost tipping over the edge.
“Cum for me then.”
Atsumu almost screams as he cums, clenching down so tightly that Sakusa cums not shortly after. Atsume slumps against Sakusa, panting heavily, as they both ride out the high of their orgasms.
Sakusa slowly slips out of Atsumu, making sure they don’t fall over in the process. He lays them down on Atsumu’s bed, the man immediately cuddling up to him.
“We can do that more often too, if you’d like.” He mutters, sleepiness lining his voice.
Sakusa moves a hand through his hair, smiling at him a little too fondly. “I’d like that.”
