Drarry into the omegaverse

Draco has a thing for vampires

"Harry you can't just hide being a vampire from Draco" Hermione sat down on the couch next to Harry.
"Once I get my powers and my urges under control I'll be able to hide it from him" Harry says.
"You can't lie to your husband -"
"It's not lying"
"It's a lie by omission, look, if you go home and tell Draco you got turned into a vampire he'll still love you just the same, but if you keep it from him, he'll get mad at you for hiding it when you eventually do tell him" 
"No! How could he love a monster"
Hermione sighs and called pansy. "Pansy I need you to tell Harry about Draco's vampire fetish!" She said
"Oh yeah, Draco reads a lot of vampire based smut books. Nott pretended to be a vampire to date Draco. Draco broke up with him when he found out Nott lied to him"
"Really you're not gonna ask why? You'd just expose Draco like that?"
"Oh, news of Harry's fight with the vampire is all over the papers"
"Shit." Harry had forgotten how fast news traveled despite the primative methods "so Draco..."
"Already knows" Hermione nods.
Harry sighs and stepped into the fireplace grabbing some floo powder "grimmuald place" he said.
Draco ran to the fireplace when he heard the flames of the floor network arrive. "Harry! Are you okay?" Draco cups Harry's cheek and looked at Harry's fangs "so it's true"
Harry looks down "I can leave if you want-"
Draco waved his wand and a paper flew into his hand, he handed it to Harry "here's a list of things I want you using your newfound vampire powers for"
Harry stared at the list  "you want me to feed on you during sex? Fuck you with vampire speed? Change you on our wedding night?"
Draco nods "we can be together forever now~"
"I'm not gonna turn you-"
"Then you'll never have a lover after me" Draco said
"What?"
"You're not allowed to date or marry or even fancy anyone after me, you'll spend the rest of your eternal life mourning me until you eventually succumb to your grief and die of a broken heart"
"Don't you want me to be happy again?"
"Not without me" Draco says
"And you're not going to abandon me before I can die and break your heart!"
"Draco, don't you think that's asking a lot of me?"
"No, asking you to recreate the twilight series with me would be asking a lot, this is the bare minimum"
"At minimum I have to die if a broken heart-"
"The closer to my death the better"
"And I can't learn to love again?"
"If you do I'll consider it cheating and beat you for it in the afterlife"
"Why can't I expect you to come back as a ghost to keep me company?"
"Because I don't want to be some old ghost, and you still can be killed. The goal is for us to be together forever"
"Draco this is insane-"
"So we agree, you'll turn me on our wedding night"
"That's not what I said-"
"It's that or spending the rest of your eternal life mourning me"
"So what happens if one of us dies as vampires?"
"I'll die of a broken heart within a week of your death, and since you keep cheating death you'll mourn me for the rest of eternity?
"So you get to die in a week and I have to live on without you? Alone forever"
"Omegas rarely take longer than a week to die after their alpha does. Every omega in my family that's outlived their alpha did so by under a week" 
"That's not an achievement, Draco"
