fever dream high

Summary:

Subaru accompanies Kou to an amusement park and doesn't let on that he's thirsty as all hell so as not to ruin their date. Because he wears his heart on his sleeve, however, Kou finds out straightaway what the problem is and happily offers himself to satisfy Subaru's need.

Work Text:

It takes every ounce of strength available to Subaru to keep his knees from buckling the moment he exits the ride, and with Kou hanging so heavily off of his arm, he’s sure that he’ll collapse any given moment. The world tilts and wobbles as he takes shaky steps onto solid ground.

“Are you sure you’re okay, hon?” asks Kou as he finally takes notice and pauses beside a bench. “Sit down for a sec and let me look you over.”

Subaru staggers forward and grunts, “I’m fine.”

Rolling his eyes, Kou yanks back on his arm as he stubbornly continue along the path and forces him to sit down instead. He fishes through his bag and produces a bottle of water, unscrewing the cap.

“This should help,” he says and takes a sip first before offering it to him. He grins as Subaru meets his gaze and winks at him. “It has a little bit of me in it now, too! Super effective!”

The pure blood narrows his eyes at the bottle and scoffs, “I’m a vampire; that’s not gonna do me any good.”

No longer amused, Kou stuffs the head of the bottle into Subaru’s mouth and holds it there.

“Human or not, you need to stay hydrated,” he mutters and tilts the bottle back, forcing a little into his boyfriend’s mouth. “Don’t look at me like that or I’ll have to kiss you until you smile again.”

Subaru pouts but takes the bottle from him, gulping down water and relishing the refreshing feeling that overwhelms him as he drinks it. That last roller coaster got the best of him, but he won’t admit that to Kou lest he be teased for the fact.

Peeking up through his bangs, Subaru grimaces. “I don’t have to tell him. I think he already knows.”

“We should take a break,” Kou decides and sits beside his boyfriend, pulling his phone out of his bag to check for any missed calls or messages. He swings his legs to and fro, humming a little tune, and the way the light hits his pretty, blonde hair just right gives him a glow akin to a halo. Kou looks up from his phone to catch Subaru staring. “Aw, are you admiring me?”

Subaru takes another gulp of water and quickly looks away. “You’d like that, wouldn’t you.”

Kou shrugs and puts his phone away. “I already know that you’re mine and how you feel about me, so the whole tsundere act kinda lost its effect a while ago.”

Choking on his next sip of water, Subaru hunches over and coughs violently.

“Not that I don’t enjoy seeing you so cute and flustered, though,” Kou adds while he pats and rubs his boyfriend’s back with some measure of sympathy. His fingers trail up Subaru’s spine, around the base of his neck, and into his hair to settle on his cheek. “I mean, like, you’re just so fucking pretty. How could anyone not enjoy being in your company?”

Attention and praise are two surefire ways to arouse Subaru’s serotonin levels, and Kou delivers every time. Like a moth drawn to the flame, the pure blood can’t resist or ever get enough of that affection, so he keeps on coming back with his guard dropped a little more each time.

Staring intently into Kou’s direction, he plucks something from his hair very gently. “You had a leaf in there.”

“I-I…” Kou stammers and his face turns a bright pink with the close, sudden contact.

Cheeky, Subaru smirks and teases him, “Now who’s flustered, huh? Serves you right.”

The way the pure blood struts his stuff and exudes pride has Kou’s stomach all tied up in knots.. He scoots so close to Subaru that he’s almost in his lap, wrapping one of his legs around Subaru’s as he leans in shyly and asks, “Could you do that again?”

“What?” Subaru grunts and backs into the head of the bench. “I-I don’t know what you mean.”

Kou takes his hand and moves it into his hair again, simulating the gentle rubbing motion that Subaru accidentally graced him with moments ago.

“Please?”

Those big, blue eyes are hard to say no to and Subaru is already a sucker when it comes to indulging every selfish little request that the other vampire makes of him. He surrenders with a sigh and lets his fingertips graze Kou’s scalp while he runs his fingers through his hair.

“You’re like a cat,” he says with a smile trying to break out onto his lips. “Geez.”

Kou pushes against his hand and climbs into his lap at last, shocking and catching the attention of a few amusement park goers around them but he could care less. He feels so safe and warm in Subaru’s arms, like nothing could ever hurt him here, and he wraps his arms around Subaru’s neck to hug him.

“C-Come on,” Subaru complains but hugs him back nevertheless. “Cut it out.”

Pressing his lips to the top of Subaru’s head, Kou refuses, “Nope.”

With the curve of Kou’s neck practically forced up against his nose and mouth, Subaru smells the sweet mix of perfume and blood with a sigh. His fangs start to ache and he makes that weird, whiny noise into Kou’s ear to make his need known.

“Thirsty, kitten?” Kou asks, pinpointing the problem at last as he pulls back to smile gently at his boyfriend. “You should have told me when we got here.”

Subaru frowns. “I didn’t wanna ruin our day. You were really looking forward to – Mmph!”

Kou leans down and kisses him on the mouth this time, long and hard. Saliva spills out between their lips as they slide over one another and Subaru’s need grows greater than before. He pulls Kou off of him and gasps for air.

“Let’s go,” Kou says and hops off of his lap as if they didn’t just put on a show for the rest of the people at the park. “There has to be a bathroom or something around here.”

Subaru blushes into his ears and takes the hand outstretched to him, matching Kou’s buoyant stride along the boardwalk. “Thanks.”

Kou looks back and winks at him. “Just be sure to tell me next time, ‘kay?”

Nodding, Subaru follows him into a public restroom and an empty stall all the way at the end of the building. Kou pushes him against the wall and inclines his neck at an angle for his ease of access and pleasure.

“I’m all yours~”

With hunger burning deep within his throat and singing the shame right out of him, Subaru softly whispers his thanks and plunges his fangs into Kou’s neck.
