Y/n's POV
I woke up this morning feeling rested. More than usual though.
I got out of bed to use the bathroom and get ready to go out for breakfast.
When I came out Jungkook was running around, acting crazy.
Jungkook: "Y/N WHERE WERE YOU?! I THOUGHT YOU WERE GONE FOREVER WHEN I WOKE UP AND YOU WERE GONE! HOW COULD YOU ABANDON ME LIKE THIS?!?
"Jungkook I was getting ready so we could go out for breakfast and decided not to wake you up because you were sleeping so peacefully."
Jungkook: "Oh well...don't ever scare me like that again." he said breathlessly.
He then suddenly ran up to me and wrapped his arms around my waist. I had no other choice but to hold on to his neck to keep me from falling or being in an award position.
That's when I felt it. Teeth going into my neck. So this boy is a vampire too now!?
"Jungkook-...ahh (wincing not moaning🤦🏽♀️😂)"
"JUNGKOOK WHAT ARE YOU DOING I THOUGHT YOU WERE A DEMON NOT A VAMPIRE!"
He finally took his teeth out of my goddamn neck and started to explain what he was doing.
Jungkook: "So...I just marked you. It's kinda like what werewolves have in stories...uhhh..umm...MATES! That's it. I also just turned you into a demon. Demons can only have Demon mates so I had too. You are mine and only mine. Demons also have the need to drink blood. We are not vampires though. The only supernatural beings that really exist are Demons, Angels, and dwarves. Dwarves being the beings with a small amount of power. Soon because you are my mate you will feel the effects of being a demon and will need to drink my blood and mine only."
"Are you fucking serious right now?"
As soon as I said that my eyes went red and I felt a burning sensation in my throat.
"You're changing." was all he said.
I started to scream. My senses went crazy. I could hear shit from a mile away and smell things that I couldn't smell before.
I glanced and Jungkook and got a whiff of his blood. And Lord have mercy it was my biggest craving right now.
Jungkook: "Only mates can drink each others blood and be satisfied. Go ahead Y/n."
I didn't hesitate to pounce on him making us land on the bed.
(Don't think negative like me my little nasties)

Determined to get my blood, I pushed him back and leaned into his neck.
Jungkook: "Go ahead...its all yours." he smirked in satisfaction.
I didn't care if it was stinky old Jungkook. I WANTED MY BLOOD.
I sunk my newly grown fangs into his neck.
When I felt the blood pour into my mouth I hummed in satisfaction. It tasted so good. Like cherries and cream. I just couldn't stop. I wanted more and more.
Jungkook: "Take as much as you need. I'll be able to survive even without blood."
Even then I decided that what I had was enough. For my first time having my mates blood it was delicious.
