You shivered a little, and that stirred you from your sleep. Your arms were sore and when you went to rub your eyes, you hissed at the sharp pain that went through your wrist and the rest of your arm. Why were they above your head?

God you felt like shit.
Your eyes opened to pure dark. You searched for any shred of light, but there wasn't any. How the fuck did you even get here and why was it so dark?
There was no sound.
Just silence.
Just dark.
You scanned again after a few minutes, and then you saw them.
Two red rings.
Two red eyes.
You knew those eyes.
Everyone did.
"You."
You just happened to know them better than most people.
"Me."
A dim light flickered on and there he was, smirking. He was always smirking.
The bastard.
"No shit, what the fuck do want, asswipe?" His smirk widened at your insult. "Don't play dumb. You know what I want."
He was coming closer, and fuck, did you want to kick him right now. And you would. If your ankle wasn't shackled to the floor. "Karkat." He whispered, holding your chin up gently with his hand.
You did know. That wasn't just your name. It was a statement. He wanted you. Dave had always wanted you. But you were used to hate and hostility. His love had been overwhelming. He can't say you never gave him a chance though.
Your eyes widened. It all made sense now. The kidnapping, the shackling, the gentle touch. He was going to take what he wanted, by force.
"You don't have many choices right now, you know." Why did he have to be right? "Tell me you love me." Of course. Of. Fucking. Course.
This wasn't Dave. Real Dave would have never done this. This was demon Dave. Red eyes before, now red orbs of evil, striking fear into even those lucky enough to never of had the misfortune of seeing them. He would have learned from his mistake and sneaked his way into your heart. Even after you broke up with him, and maybe even broke his heart in the process. Real Dave would have done a bunch of things demon Dave wouldn't.
And vice-versa all the same.
"I'd sooner bite my own legs off." His smirk feel into a frown. "If you want pain, I can do it for you. No need to hurt yourself."
Why was he being so goddamn formal? It was annoying and Jesus, did you want to punch him now. "Tell me you love me, Karkat." You glared at him, eyes narrowed, eyebrows adding emphasis to your defiance, despite lack of ability to do anything in the areas of both offense and defense.
"So you don't love me."
Why did your face have to soften?
Why did you have to have feelings?
You didn't respond.
You did love Dave.
Real Dave.
He stared at you, a neutral expression.
This was Dave, wasn't it? This was the new real Dave. Sure, the old one was there somewhere, under a layer of evil from being a demon, but this was Dave. Thoughts flooded your mind and you started to cry, tears brimming your bottom eye lids. It might take time, but you could love him. Love him like he wanted you to love him.
You could be Karkat under a layer of evil from being a demon.
You knew you loved him enough.
Enough to be what he wanted.
A couple.
Or at least try again.
"Shit you're crying, uh…" He wrapped his arms sheepishly around you and your tears fell onto his shoulder. "D-Dave I…" He patted your back lightly.
"I can't hug you back."
He pulled away to read your face, a tear sliding down your cheeks and soaking into your collar.
He could tell this was genuine. "D-Dave, I…want you to turn me…i-if you can…then I'll say it." The corner of his lips turned up into a small smile, then he hugged you again.
"This is gonna hurt like a bitch."
His fangs plunged into the area between your neck and shoulder. He unshackled you and the lights turned off as he left the room, locking it behind him.
A searing heat boiled in your blood and it felt like a fire had been set ablaze in your stomach and a loud scream ripped from your throat.
At some point it died down, leaving you hot, weak and limp on the hard, but thankfully cold, floor. Dave came back with a jar of something red and handed it to you. You opened it up and took a sip, too thirsty to care at the moment what it was until after you drank some down.
"What is that anyway?"
He narrowed his eyes a bit.
"Hand me the jar." So you hesitantly gave it back to him.
"Blood."
Your hands went to your neck. "You - and I - HOLY FUCKING SHIT, DAVE."
"You kinda need it to get your strength back, and oh yeah - LIVE. Don't be a shit about it Karkat. It's easier when you embrace it."
Fair enough you guess.
Then there was this urge. This urge to fuck something senseless, and your eyes traveled to Dave.
He could feel it too.
"Did I forget to mention it's mating season for demons?" He smirked at you. "Well woops."
You growled at him "Son of a bitch."
He didn't get to say anything before your lips were against his, hand sliding under his shirt. He smirked into the kiss and pulled you to your feet.
You wrapped your arms around his neck, lips working against his while Dave worked to undo your pants. You wiggled them to your ankles and stepped out, pulling his shirt off.
It was all so clumsy and needy, and it was beautiful.
You got your own shirt off as he undid and slid off his own jeans, getting them acquainted with the floor, followed suit by both pairs of boxers.
Everything was on the floor now, which was still pretty cold. He dug around in his pant's back pocket for a condom and lube. "Shit, looks like we gotta go in dry."
"OH FUCK NO."
"Kidding, kidding."
He took them and lubed up his fingers, slowly pushing one in. It was weird. Not bad, but not good either. Further in it went until you adjusted and gave him the okay to add another. With each scissor, you hissed until it was enough time and he took it as a sign to add the third, thrusting the digits.
You knew what he was doing too.
And the bastard found it, brushing your prostate and pulling a small moan from you, one ending in a whimper as he pulled them out.
"God you're an adorable little shit."
You reached out and jerked him by the hair. "Shut the fuck up and fuck me." Letting him go as he smirked again.
Dave shivered as he pushed in "Holy shit, how can you even be this hot and tight at the same time?"
He started to pull out. "Don't you dare-" You moaned as he hit your prostate on the first thrust, and the rest of your words came out breathy and forced "Come yet."
His pace picked up quickly and you reached up to pump your ignored member, making sure to stay in time with his thrusting.
With one last thrust, you both went spilling over, seed spilling onto your own hand and he licked it off.
He pulled out, laying next to you. "Someone's a cuddler." He made a small 'pfft' noise "Yeah, kinda. Shut up. You know you wanna cuddle too." You sighed, but smiled at him, tracing your tongue over your fangs.
At least they didn't get in the way of kissing, you thought, pecking him on the lips again, rubbing the arm he had wrapped around you.
It was still going to take time getting used to, but with Dave as your guide, you're sure it won't be too bad.

"I love you Dave."
But he was silent, asleep cuddling into your chest.
