Pale, dawn sunlight filtered through Seokjin's slightly open blinds, and Taehyung's eyes fluttered open. He felt stiff, and he was surprised to see his lover's angelic face sleeping soundly next to him. When had he fallen next to him?

"Mmf," Seokjin mumbled, burying his face into Taehyung's chest and hooking his legs over the younger's muscular legs comfortably. "M- no..."

Taehyung let out a soft, amused chuckle. "No what?"

"No..." Seokjin breathed out, puffing out his cheeks, "he's no...not yours."

Taehyung laughed and brushed their noses together, leaning down to sniff at his neck, mouth watering at how tasty his mate smelled. As he continued to lick and prod at his flesh, Seokjin let out a soft little moan and rutted his hips against Taehyung's thighs.

Taking that as a sigh of consent, he allowed Seokjin to pleasure himself against his thigh as he gently scraped his fangs against Seokjin's shoulders. Taehyung murmured against Seokjin's warm skin.

As he fed from Seokjin's blood, drinking the sweet liquid, he smirked against Seokjin's skin as he felt something warm spatter across his bare legs, and a soft moan to come from Seokjin's lips. He lapped over the bite wound to heal it, and Seokjin's eyes flickered open.

"Why am I so tired?" He croaked, before looking down at the blood smeared across Taehyung's lips and his come on Taehyung's thighs. Eyes slowly widening, he caught Taehyung's mischievous gaze. "We didn't—?"

"No, but were you having wet dreams of me, baby?" Taehyung asked, cupping his chin. "That's hot."

"Um, w-well—"

"Save it for later, sweetheart. You've made such a mess." Taehyung reached down to scoop Seokjin's cum off his legs before wiping it across his lover's cheek, watching as the male let out a disgusted noise. "Let's take a bath, yeah?"

-

After the bath, Seokjin could be found curled up on the sofa, eyes narrowed in content as Taehyung massaged his shoulders with his surprisingly warm hands. He had always expected vampires to be cold, inside and out. Maybe he was wrong, maybe he was just being judgmental...

"Y'know, I dunno what came over me yesterday,"

Seokjin tensed up as Taehyung leaned over and murmured softly into his ear. "I just felt so submissive, and you know that's not like me." There was a questioning tone in his voice. "Do you know anything about that?"

Seokjin wriggled his toes and shrugged. "I don't know." His voice was tight, "Why do you ask?"

Taehyung smirked. "I know you did something baby~ now spill it before I force you to~"

Seokjin swallowed as Taehyung ran his teeth along Seokjin's shoulder. He really wasn't in the mood to let Taehyung drink, he was already exhausted from this morning's session and he wasn't looking forward to another one.

"I didn't do anything, Tae," Seokjin said, trying to keep his voice level. "You must've been tired."

Taehyung blinked, then laughed. "You really are a silly little human." His hands suddenly clasped around Seokjin's neck, and he whimpered as Taehyung's eyes flashed red and his lips drew back in a furious snarl, "Did you try to power over me? You are my submissive, I am not yours."

Seokjin choked as his throat was constricted from air and he spat and gasped for air. Spit drooled down his cheek and he squirmed around, eyes watering at the lack of oxygen. Taehyung only watched, his red eyes cold, his handsome face staring straight into Seokjin's.

"H-stop..." he wheezed out, his limbs going slack. He heard Taehyung laugh. His eyes rolled back, and he felt his body convulsing as it screamed for air. He won't kill me, we both signed the oath. If one dies, the other will, too, surely?

"I've always wondered what blood tasted like when it wasn't carrying oxygen..."

And with that, teeth broke skin, blood poured, and Seokjin screamed with the last bit of oxygen he held.

-

The morning sunlight was hazy, and Seokjin felt as if he couldn't breathe. Drowning in an ocean of his lover's scent, he felt fear stir in his stomach and Taehyung's sleepy face came into view.

But instead of warmly wishing him a good morning, he leaned in and bit down on his ear, licking the sweet skin under. "Did you learn your lesson?"

Seokjin didn't respond, exhaustion flooding his limbs. He felt Taehyung lean against the inside of his neck, smirking. "I hope you don't meet her again."

Seokjin swallowed thickly. "Wh-who?"

"JJ." Taehyung replied. "She's a bitch, a delusional idiot that buys potions from witches, and uses them on her husband. I feel bad for him, and I hope you stop meeting her."

Seokjin winced as Taehyung wrapped his slender fingers around his neck. He ghosted his lips along the fading bite mark on his neck.

"You know the drill."
