Hi! So, I had a dream where people were complaining about the lack of vampires in my current fic (Fatherhood) bearing in mind there is no supernatural elements in that fic, but anyway, after that my mind wandered and decided this needed to be written...

Why do omega vampires still get heats? Who knows! This is a oneshot and I ain't thinking that deep (they can't get pregnant though)

They are both 25 (well add a few hundred years onto that for Dazai) they have been dating since Chuuya was 20.

As there's a few different definitions of Glamour - my version uses the vampires eyes to spell the human into doing whatever they want, sort of like compulsion - Dazai uses his to make Chuuya let go a bit so he's almost high, without the drugs and let him have some fun in the bedroom (but they can use it for bad) In this universe Vampires get made when the vamp almost drains the human, and the human ingests some of the vampires blood at the same time.

This is not a part of my omegaverse series (Dazai and Chuuya's Happy Family), I just got a bit sidetracked

When Chuuya had agreed to being his sole source of food, Dazai had asked for one night, every other month, where he could feast and gorge on his blood, taking only a sensible amount the rest of the time. He promised to make it worth Chuuya's time, using glamour to put him into the perfect, floaty headspace, then fucking him through the high as Dazai dined, taking Chuuya to the edge of life and death. He would then spend the next few days pampering and caring for Chuuya as he recovered from the night.

Dazai had been looking forward to this day all week. He'd practically starved himself, and they were so close to his feast beginning.

A naked Chuuya was spread out under him, seconds away from Dazai's glamour taking full hold, almost in that blissful state that Dazai wanted him in. But Dazai was getting too hot, and the hazy look in Chuuya's eyes was starting to move into a different sort of hunger, the wrong sort of hunger for nights like this. The wetness trailing down his legs confirmed what Dazai didn't want to believe – his heat had started. He must've counted the days since his last heat wrong, you think he'd have got the hang of it by now. His view shifted as Chuuya's alpha instincts kicked in, even Dazai's strong glamour wasn't enough to completely control their alpha and omega instincts.

"Mmmm you smell soooo good Dazai" Chuuya slurred as he pinned Dazai to the bed and started nuzzling his neck,

"Yes I know, but," Dazai tried shifting Chuuya's attention away from his own neck, "but I still need to feed Chuuya," his fang was almost on Chuuya's neck when his head moved and started making his way down Dazai's body.

"Hmm how about I make you feel good first," his movements were sloppy and he looked taken aback when Dazai's stomach let out a loud growl

"Please Chuuya…stay still damnit" Dazai had settled for trying to get a grip on Chuuya's arm, which was swiftly taken away from him, as Chuuya tried to prepare him, poking and prodding Dazai's upper thigh.

"Tha' good Dazai?"

"Yes. It's so good Chuuya." Dazai tried to add some emotion to his voice and failed, under normal circumstances Chuuya would have hit for a reply like that.

This was why he never did this when he was in heat, Chuuya was easily swayed by his omega pheromones as it was, breaking down his defences with glamour just broke the whole thing. As Chuuya continued to miss his ass, and stay too far away for Dazai to eat, he growled in frustration, he couldn't feed or get fucked.

What a terrible night this was turning out to be.

He had to try a different tactic,

"Chuuya, my love,"

Chuuya stopped and looked expectantly at Dazai,

"You've done ever so good a job, I'm ready for you…" he trailed off, batting his eyelashes, and spreading his legs to encourage Chuuya where he wanted him. If Dazai was right, Chuuya would probably knot him on the first fuck and then he could finally, finally get that sweet, delicious blood.

They both moaned as Chuuya finally entered Dazai.

"Hmmm you smell so good tonight Da, Dizzy, ha ha ha, Dazai, lemme bite you,"

"Have you, you forgotten I'm the vampire?"

"I only want to bond with you, my gorgeous omega," Chuuya started nuzzling his neck again, mouthing at Dazai's scent glands. Dazai jerked his head out of the way,

"No."

"Hmmph"

Chuuya started kissing Dazai's neck instead, earning a moan from the vampire. Chuuya was finally staying still enough for Dazai to start licking at his neck, fangs itching to sink into Chuuya's delicate skin.

"I'm close," Chuuya groaned into Dazai's neck

"Perfect"

Dazai's fangs sunk into Chuuya's neck, just as they both tipped over into pleasure. Chuuya's screams muffled against Dazai's neck as the venom in his fangs heightened Chuuya's pleasure.

"What the fuck Dazai!" Chuuya's voice rang out from the bathroom, door slamming as he made his way back into the bedroom. Dazai hid further under the covers, he was tired, and may have fed on Chuuya a bit too much resulting in him feeling almost hungover.

"Get. Up. Now!" Chuuya demanded.

"Urgh, you're too loud Chibi" he groaned, he ached all over, he didn't care what Chuuya wanted it could wait.

"I'm allowed to be loud when some," he ripped the covers off Dazai, "shitty vampire turned me into one of them!"

"Stop being melodramatic chibi, I can't have," he groaned as he sat up, moving his head, his neck felt…sticky, like he'd been bleeding.He moved his hand up to it and felt the tell-tale ring of (human) teeth around his scent glands, a bit too deep

"You…you bonded with me?"

"You did worse to me Dazai."

"If someone didn't have weirdly sharp teeth for a human we would have been fine. I told you I didn't want to bond yet." Dazai sighed, a few more months and he'd had Chuuya's turning planned down to the last detail. It would have been the perfect start to their eternal life together. He finally met Chuuya's eyes, they now had the tell tale red ring, and his fangs were on display. Despite his yelling he didn't actually look angry.

"How do you look even hotter?!"

"That's all you have to say for yourself?"

"Hmm, Chuuya would have been a vampire soon enough anyway, does it matter? It's not like you have any ties to the human world…"

"Stop ruining my anger with logic," Chuuya huffed,

"I've had plenty of practice," Dazai grinned, as he pulled Chuuya in for a kiss, Chuuya moaned.

"Oh, this feels amazing, why didn't you turn me sooner?"

"Chibi needed time, wait till we have sex, oh and biting" Dazai pulled him in for another kiss. "We haven't got any plans today…" Dazai smirked, and pulled Chuuya onto the bed, suddenly determined to finish what he had started the night before.

Chuuya was never going to let Dazai forget how he had turned him, and the reactions of their friends to the news Dazai had accidentally turned Chuuya during heat fuelled sex was going to haunt him for the next century (or so.)

But they were happy, who wouldn't be, when they got to spend eternity with their one true love?
