“Katsuki, slow down.”
“Fuckin’—need you right now, baby, c’mon.”
“Okay, hang on, just—”
“Shou, for fuck’s sake!” Katsuki pulls back harshly, lips kiss-bitten with fresh blood smeared across messily.
He looks gorgeous, spread out under Shouto like this. Legs parted, body open for him. His naked skin flushed, gleaming with a layer of sweat. Shouto wants to dip back down to take the nipple ring in his mouth but locks eyes with Katsuki instead.
They’re filled with hurt and anger.
“If you don’t want me then just say so,” he growls, voice hitching.
“You know it’s not that.” Shouto frowns. He cups Katsuki’s cheek. Gets swatted away.
“Could’a fooled me.”
“Don’t say that.”
Katsuki sneers, “Then for once, could you kiss me like you mean it and not like you think you’re committing the world’s greatest sin? You’ve killed people, and so have I. What’s the damn problem?”
Shouto clenches his jaw. Those aren’t particularly fond memories but Katsuki isn’t wrong. But somehow the guilt of bloodlust-induced murders over the course of his three-hundred years of being undead were easier to overcome than this thing he’s initiated with Katsuki. This…romance.
“You don’t think I’m…despicable?” Shouto asks quietly.
Katsuki lifts a brow. “The hell? Why would I? ‘Cause you’re a bloodsucker?”
“No, not that. For—pursuing you.” Shouto bites down on his lip. “I’ve known you since you were a pup. I knew your parents as children. I’m old, Katsuki and you’re…”
“Nineteen and hot as fuck?”
Shouto huffs and shakes his head fondly. “I mean, we both look the same age but yes. That.”
Katsuki rolls his eyes but his expression softens. Shouto almost recoils at the understanding and warmth offered to his cold, dead heart. The first to do so openly in all his years on this earth. It’s why he fell for Katsuki in the first place.
“S’that why you’ve been so weird with me since we started going out?” Katsuki asks, running a hand down Shouto’s bare back and up. Runs his claws lightly through Shouto’s hair. “You feel like, what? A freak? Well, you already are one so suck it up. This is different, we’re different. I want you. And if you want me too, you better show me for real. ‘Cause this ain’t it.”
Affection floods every hollow and crevice of Shouto’s chest. He smiles and leans in for a kiss.
“Okay,” Shouto breathes into Katsuki’s mouth. That’s enough assurance for him. It’s what he needed to hear. “Okay, I’m sorry. I’ll do better.”
Katsuki readjusts beneath him, sharply nipping Shouto’s jaw with his werewolf canines. Takes Shouto’s hard cock in his rough palm. He grins. “Damn right you will. Now fuck me good, ya geezer.”
Shouto pouts at that, making Katsuki cackle. But the gleeful laughter turns into a low, sultry moan when Shouto pushes into Katsuki, slow and deep.
Teasing, he says, “Careful what you wish for, young one.”
Katsuki laughs, light and breathy and wonderful. His eyes shine with feral delight. “Now why would I do that?”
