Consensual blood drinking in this chapter.

Edited

Chapter 5

Harry hung up and swore, this was what he had been dreading ever since he had given Prompto his blood. It happened to everyone, but he had hoped Prompto wouldn't have to deal with it for a few more years. He packed up his camp, shrank his bike, and then Apparated. He appeared outside of Insomnia and found a spot to slip through the wall and into the city, avoiding the Gates. His first stop was the Argentum home to grab some blood packs for Prompto, just in case. He then tracked his Childe down, finding a heavily secured apartment building but the security was not designed for someone like him.

He slipped into the apartment silently, looking around curiously. It was obviously the home of a teenager, schoolwork and game systems strewn about but overall it wasn't that messy. He went to the kitchen and put some hot chocolate on since it was likely to be needed and then went to find the boys, smirking slightly when he found them both in the Master bedroom, the Prince wrapped around Prompto, an arm secure around his stomach. They looked so cute like that.

He moved to stand at the foot of the bed, arms crossed, and waited for one of them to realise he was there. Unsurprisingly, Prompto woke first, sensing his closeness and feeling safe due to it. He watched as the Prince woke, reacting to the change in Prompto, smiling when the Prince didn't let go. "Do I need to give the Prince a talk about intentions?" he asked, still smirking.

"DAD!" Prompto groaned and Harry saw the Prince looking from him to Prompto, obviously not seeing the resemblance.

"Get up boys, I've got hot chocolate warming," he offered, bowing ever so slightly to the young Prince before leaving the room.

,,,,,,,,,,,,,,,,

Prompto groaned, rolling over to face Noctis. "Sorry about that, Dad has a warped sense of humour."

"You don't look like him," Noctis offered.

"See us next to each other and its more obvious. Grandmum was a redhead, that's where the red tint in my hair is from," Prompto explained, stretching. He felt good this morning, settled, content. He inhaled deeply, letting Noct's scent wrap around him.

,,,,,,,,,,,,,,,,,,,,

Noctis noticed Prompto taking deep breaths, was he smelling him? Did he smell? He'd showered before bed so it couldn't be that bad, could it? Prom could obviously smell more than he could. "What do I smell like to you?" he asked and then tried to look unconcerned.

"Lightning, steel, cinnamon and some sort of flower," Prompto answered after a second.

"So, not bad?"

"No, not at all," Prompto said quickly and Noctis blinked, was Prom blushing slightly?

"Boys!" Prompto's Dad called and Prompto sat up, hair a wild mess. They each went to a different bathroom to change and wash up before going to sit on the couch and accept hot chocolate.

,,,,,,,,,,,,,,,,,,,,,,,,

Harry sat down opposite them. "I am sorry we are meeting like this Prince Noctis; I had hoped for a more relaxed meeting of my Childe's best friend," he offered the young man.

Noctis nodded, gripping his mug tightly. "Noctis or Noct is fine, sir. This isn't exactly formal, though…we probably won't be alone for long."

"Don't worry, we won't be disturbed, anyone who wants to come to the apartment will find themselves remembering something important they need to do immediately," Harry assured him, looking between them both, no longer teasing. "Now, Prompto told me the barebones on the phone. I would like to hear what happened in full, from both of you."

He watched as his Childe, his son, took a deep breath, staring at the floor. He hid a smile when the Prince, reached out to take his hand. That was very interesting though complicated due to the obligations of Royalty. He listened as Prompto explained the attack and his own actions, everything, the Prince butting in to deny or confirm as few things, like denying he was ever in danger from Prompto.

"How do you feel now?" He asked gently and Prompto finally glanced up at him, if only for a second.

"Full…settled," he whispered, and Harry smiled when he saw the Prince squeeze his hand.

"Then Noct is right, there is no danger to him," he promised but Prompto shook his head.

"He smells so good Dad, better than anyone else. I…" Prompto whispered too softly for Noctis to hear.

"Ah." Well, that explained a lot. He knew Prompto hated living in the city, but he would never say why he had chosen to stay. Now it was obvious. It was easy to see they both cared deeply for the other, but he also knew of the hopeful whispers, that one day the Prince and Oracle would wed. Why when they had only met once he didn't know, but it gave people hope. "Alright, first thing first. Noct, Prompto is in no physical danger," he told the teen seriously. "He is not a daemon or infected with the Scourge either. For more details I will need your oath that you will never speak of what I will tell you with anyone, without Prompto or my permission."

,,,,,,,,,,,,

That definitely got Noctis' attention. That was not the sort of oath a Prince could give lightly. He looked at Prom's Dad, green eyes deadly serious and then over at Prompto who was sitting carefully, obviously trying not to influence him, but he knew his friend, could tell he was torn between hope and fear. He felt very confused; he didn't even know how Mr Argentum had gotten into the apartment! But… "I swear." He felt the Crystals magic surge in his veins strangely and then there was a flash of light.

,,,,,,,,,,,,,,,,

Harry was happy the oath had taken, the magic would protect Noctis, ensuring no one could make him tell and he couldn't accidentally let something slip. He hadn't been sure it would work due to how different modern magic was. He missed the days of wizards, when magic flowed freely through the Earth. The magic was still there, locked away in Ley lines, Insomnia was built on one…one he had spent years living over as a teenager. The Citadel stood where Hogwarts once had, though there was nothing left of the once grand castle, unless you dug down far beneath the foundations of the current 'castle'.

If not for that meteor there would be more magic and perhaps magical people. As it had approached the planet had reacted to preserve itself, using magic to slow the thing until the Astral, Titan, had moved to intercept it, keeping it from crashing into the planet. The meteor was strange, and the planet had never truly recovered from the attempt to stop it. The animals of the planet had mutated into creatures unheard of before and the last magical human had been born three years after it hit. After that, only the Astrals and their chosen humans had magic, although there were people born who would have been magical, those people did especially well in the Crownsguard and Kingsglaive, using the King's magic instead of magic of their own.

He settled in and explained such things to a wide eyed Prince, who had learnt his history from such things as the Cosmogony. He didn't bother going back to the dinosaurs or even Rome, but he did speak of the times he had grown up in and then on to when that world had been all but destroyed, leading to the arrival of the Astrals and their impact on humanity, then Solheim and on to what he knew of the truth of the Oracles and Lucii, including Ardyn and Somnus.

"How can you know all this?" Noctis finally asked when Harry's story reached Noctis' own birth.

"Because I was there for a lot of it."

"That's impossible…that's thousands of years!"

"Yes, it is," Harry confirmed.

,,,,,,,,,,,,,,,,,,,

Thousands of years old? How was that possible? He glanced at Prompto, how old was he? Did he even believe this? It sounded crazy, but neither Argentum looked crazy.

"I'm fifteen," Prompto spoke up, and Noctis started, getting a small smile. "Could see you wondering. I'm a few months younger than you for real. It's just Dad who's older than current civilisation."

"Prompto is my youngest, and only living, Childe," Mr Argentum agreed. "In the old world there were many species, some of them who lived long beyond a human lifespan. I was born human but became a vampire when I was eighteen. Vampires are magical creatures that are stronger and faster than humans by several magnitudes. In exchange they do not eat human food but require blood."

Noctis turned his head to look at Prompto. "You drank that man's blood…"

,,,,,,,,,,,,,,,,

"Prompto is a dhampyr; half vampire, half human. He drinks blood but he also eats human food," Harry cut in smoothly, glancing at his Childe, was he willing to have his whole past revealed now? It was his choice to make but if he kept it secret then sooner or later it would come out and it would hurt Noctis to find out he'd hidden it.

,,,,,,,,,,,,,,,,

Prompto swallowed hard but took a deep breath. "I was…created in a lab in Niflheim, a clone for the Magitek Infantry. For six years I was treated as a unit, not a person, trained all the time, injected with the Scourge. But…I wasn't good enough, too emotional, too slow. So I was scheduled for decommissioning. If Dad hadn't come snooping, I would be almost six years dead. He got me out." He shakily undid his bracelets and held his right arm out, revealing the barcode on his wrist.

He only ever took them off when alone or with his Dad, no one else had ever seen his bare wrist and he was terrified to show it now, but if he was telling him everything then at least he could show this proof.

,,,,,,,,,,,,,,,

Noctis heard Prompto's words but they didn't make sense and then he took off the bracelets that he always wore, revealing the marked skin and the horror began sinking in. Someone had…he swallowed hard, stomach churning. How could anyone do that? To make babies to turn into those…those things?

"Head between your legs," a voice ordered, pushing his head down and he let it happen, head spinning. A hand gently rubbed his back and he gasped for air. "Breath slowly."

"Noct? Come on, breath with me," Prompto's voice reached him, then there was a hand on his chest, and another was lifting his hand to rest over Prompto's shirt.

Noctis listened, struggling to get his breathing under control and then he looked up into worried blue eyes and he threw himself forward, wrapping his arms around his best friend, hearing him squawk in surprise.

"Noct?"

"I'm sorry," Noctis whispered, clinging to him like he'd vanish if he let go.

"For what?" Prompto asked, his own arms slowly wrapping around Noctis.

"What they did to you…no one deserves that," he choked out and then looked over at Prompto's Dad. "Thank you for saving him Mr Argentum."

,,,,,,,,,,,,,,

"It's Harry," Harry told him with a soft, proud, smile. "And no thanks are necessary."

He moved back to his seat now that the Prince was breathing. His reaction helped, such horror was not easy to fake, especially for someone so young, and it showed the boy had good moral strength. Harry could tell that he would be a good King one day. "Are you ready to continue?" he asked gently.

Prompto sat back against the couch and Noct remained plastered to his side. He nodded at Harry, an arm around the Prince and Harry smiled softy at them.

"I took Prompto and to a Haven and in doing so, I almost killed him," Harry admitted. He waited a second to see if Noctis would understand and sure enough, blue eyes went wide.

"The Scourge?"

Harry nodded. "The interaction between the magic of the Haven and the Scourge in his body began to kill him. His body was trying to expel it, but it would have killed him first."

"I remember being sick, feeling like I was choking and drowning," Prompto whispered. "It hurt worse than anything they had done to me before, but Harry didn't let go of me. That had never happened before. Then…he asked me if I wanted to live. I don't remember answering."

"It was in your eyes," Harry smiled softly in remembrance. "I'd never seen eyes that shade of violet before."

"Prom's eyes are blue," Noctis pointed out.

"Now they are. The Scourge taint had turned them purple, had he remained in the infantry they would have eventually become red," he explained and Noctis grimaced but nodded. "In order to save his life, I made him my Childe. I drained much of his blood to help remove the Scourge and then he drank my blood. That is why he gained some of the characteristics of my family. Over the millennia I have had many children, some full vampires, others half-breeds like Prompto."

,,,,,,,,,,,,,,,,,

"It was more than just blood you gave me Dad," Prompto grinned at him and then looked at Noctis. "All I knew was the Magitek production facility and training. I only spoke Gralean too. When Harry gave me his blood he also shared his knowledge of language, human interaction, how to behave, everything. He saved me Noct, gave me a real life. Before Harry I was… little more than a living machine. They did more than just put a barcode on me, I had ports in my body, for feeding, injecting the Scourge, to interface with training armour…I…I saw what happened to the older kids. They became less and less human, they became blank, empty, their eyes red, their tears black and then they'd just vanish….I'd be like that by now if they didn't kill me for not being good enough." he stared at the ground, not sure he wanted to see the expression on Noctis' face.

,,,,,,,,,,,,,,,,,,,,,

Noctis listened as Prompto explained just what Niflheim had done to him and who knew how many other kids. Because that's what they were, kids, no matter how they came to be. It made him sick that anyone could think doing that was okay. "What happened to the uh…ports?" He'd never seen Prompto without a shirt until last night, he hadn't noticed anything then, but he'd been rather focused on the already healed stab wound.

"The change forced them from his body, the only thing left is the barcode," Harry answered.

"So to save him from becoming a daemon or MT, he has to drink blood?"

Harry nodded. "Not as much or as often as a full vampire, but yes. Without doing so he will become weak and could go into bloodlust, that is something that needs to be avoided. In bloodlust he will kill and feed without any thought, he would be unable to tell friend from foe."

Noctis grimaced at that idea, suddenly realising how lucky he'd been in the alley. Part of him wanted Ignis and Gladio to know, so they could help but…the idea of bloodlust would not make them happy and he knew it. "Can I do anything to help?"

,,,,,,,,,,,,,,,,,,,,,

Prompto looked at his best friend, shocked at the offer. He'd been hoping for some sort of acceptance but this? He glanced at his Dad who just grinned at him. He'd told him that Noct would accept him. "Noct…"

Noctis twisted around to face him, face serious. "I want to help if I can. You're my best friend, I don't want you to be in danger or hungry or anything.." he paused and then looked thoughtful. "Could I store blood for you in the Armiger? I could give you access and then you'd always have blood when you needed it."

"Noct! You can't…only retainers have access to that."

Noctis just shrugged. "Technically there are no laws stopping me giving access to whoever I want. You could put some of your weapons in there too. Hang on…is that why I can never work out where you keep them? Some sort of vampire thing?"

"I was a wizard as a mortal, my magic remained when I was turned and has only grown stronger over the years. Prompto began showing signs of magic when he was nine. It will take a long time to fully develop but yes, he is using magic to keep anyone noticing he is armed. Our magic is very different to yours, more versatile in many ways."

Prompto watched Noctis as they talked, relieved to see Noctis was actually excited about him having magic. "Maybe we could have a real fight?" he glanced at his Dad.

"Pick a place and I'll ensure you're undisturbed," Harry agreed. "As for storing blood…I don't see any reason why it wouldn't work, as long as your magic didn't disturb the stasis charm on it."

,,,,,,,,,,,,,,,,,,

Noctis nodded and turned to Prompto. "Just hold still," he told his friend who nodded and Noctis leant in, pressing his lips to Prompto's forehead, feeling the Crystal's magic surge through him and into the dhampyr. He pulled back and grinned even as Prompto blushed.

"That felt…cold….but like you," Prompto told him.

"I'll teach you how to store and then pull out anything you need. You can store clothes, weapons, money… whatever you need."

"Thanks."

"Should have done it when you agreed to act as another guard," Noctis admitted, not sure why it hadn't been suggested then. Maybe because he was a secret last defence? He didn't get paid or anything and only had access to the very basic Citadel gym rather than proper training rooms. He needed to talk to his Dad and Cor about fixing that.

"I'll be staying in town for a while, in case your attackers had friends and…"

"And in case my controls shot from feeding from that man," Prompto finished for his Dad.

"I don't think that will be the case," Harry told them firmly and Noctis agreed with him. "It may…be worth considering a permanent donor."

"A what?" Noctis asked, not sure what that meant.

"Someone willing to let Prompto feed from them periodically to relieve the desire to truly feed."

Noctis blinked and then looked at Prompto, he would volunteer.

"No Noct, not you. It's too dangerous," Prompto denied, immediately knowing what he was about to say.

Noctis looked to Harry. "Is it?"

"As long as you're both careful, it could be done," he admitted and they both saw the look Prompto gave him. "I'd oversee every feeding for the first several months to ensure nothing went wrong, after that you'd both know your limits."

"Then I want to do it," Noctis told them.

,,,,,,,,,,,,,,,,,,,,

Harry kept his face calm. Yeah…best friends…he wouldn't interfere, it was up to them to realise and act or not. "It would be best to get the first feeding over now, while Prompto is still full.

"Dad…"

"Everyone else believes in you, now you need to believe in yourself," Harry told him firmly before looking back to Noctis. "Feeding can cause…side effects, especially when the blood is willingly given. Will you be able to handle that?"

"Side effects?"

"Pleasure, particularly physical pleasure. It's meant to stop a meal from struggling. Feeling elation is normal. Multiple feeds also creates a bond that can overwhelm the donor, but your own magic should protect you from that. " Harry stared at the Prince, hearing his heart rate increase, and it was obvious he was trying not to blush.

"Okay."

"You'll want to be comfortable for this so the bedroom would be best." He stood up and offered the boys a hand up each.

,,,,,,,,,,,,,,,

Noctis led them into his bedroom, he was nervous but surely that was normal. A bond? He'd just linked Prompto to his own magic so they idea of having a bond back the other way didn't bother him at all. He glanced over at the man older than his Kingdom for further instruction.

"Shirts off, in case of spillage," the vampire ordered and Prompto immediately pulled his off.

Noctis blinked, he'd never realised how muscular Prom was since he'd never seen him out of his shirt before. He was pale too, despite all the time spent in the sun. He looked away and pulled off his own, making sure neither male saw his scarred back. Harry wasn't even looking, piling the pillows up.

"Okay, Noctis, on your back against the pillows please. If at any time you want to stop, that is perfectly fine," Harry told him.

Noctis nodded and got on the bed, lying back and trying to relax. Prompto followed him onto the bed and reclined beside him.

"You sure?" Prompto asked and Noctis nodded.

"Do I need to do anything?"

"Don't pull away when he bites, that will cause tears in the skin," Harry warned, perching on the edge of the bed.

Noctis lay still, watching as Prompto took a deep breath, his eyes going silver as his fangs emerged. He nearly flinched as a hand guided his head to the side a bit, but it was just Harry helping. Prompto leant in and inhaled deeply, nuzzling at the skin and Noctis swallowed as goose bumps broke out. Something lapped at the skin and he realised it was Prompto's tongue. His skin tingled a bit, feeling funny…numb….then he felt a sharp pressure but no pain, he'd been bitten. It didn't hurt. The pressure let up and then he felt Prompto sucking at his throat, it felt…strange, but not bad. He felt Prompto's arm wrap around his waist, holding him closer. It felt…he gasped, oh…he felt his body become heavy, as his head swam, eyes closing as he moaned. It felt like he was floating, a strange feeling of euphoria overtaking him. He'd never felt anything like it.

,,,,,,,,,,,,,,,,,,,

Prompto was careful to lick at the skin of Noctis' neck, not wanting to hurt him, letting his saliva anesthetise the skin. He took his time, inhaling his scent, nuzzling the warm skin, before sinking his fangs in as carefully as he could. He let them retract and latched onto the wound, sucking at the blood. He tasted so good! As good as he smelled and he wrapped an arm around Noct's waist, pulling him closer.

He wanted him to feel as good as he did and he heard Noct gasp, body relaxing, pliant in his arms even as he moaned, and it wasn't a moan of pain. Prompto loved the sounds he pulled from Noctis as he fed, drinking very slowly, drawing it out, but eventually he was lapping at the wound, sealing it. He raised his head, licking the blood from his lips, looking down at Noctis. His eyes were closed, skin flushed, heart racing, looking utterly tempting.

"Noct?" he whispered and blue eyes fluttered open, unfocused; pupils dilated. Seeing how he had affected his friend was amazing yet also scary. How could Noct stop him if he went too far, if his feeding did this to him?

"It's alright Childe, this is why I'm here," Harry whispered, reaching over to stroke Prompto's cheek and he pressed into his Sire's touch.

He still had an arm around Noctis, and he didn't want to let go. Noct whimpered, head lolling on the pillow and Prompto pulled back enough to stare down his body, seeing the physical proof of what he was feeling. He shifted his position, pressing his thigh between Noct's legs and Noctis moaned. He leant in and nipped gently at his throat, earning a gasp and shudder even as Noct bared his throat to him, he wanted to bite again but fought the urge. Every instinct he had screamed at him to do more but he fought against them, no matter how much he wanted to claim what was being offered.

"You're doing great Childe, you can't bite again. In exchange for his blood you need to take care of him," Harry murmured. "You'll feel drawn to protect him, to care for his needs, the more you feed from him. A donor is precious and rare."

Prompto nuzzled at Noct as the human writhed against him weakly. He heard his Sire's words, yes, he wanted to look after Noct, he always had and now he could. He moved, giving Noct the friction he was looking for, earning a breathy whine.

,,,,,,,,,,,,,

Harry watched them, unaffected by the sight of his Childe and his new donor. He had warned the Prince his could happen, but he had still agreed. It was obvious Noctis was unaware of anything other than the pleasure granted by Prompto's feeding and he was proud of Prompto. Many older vampires and dhampyrs would have lost themselves in their donors body, seeking their own pleasure as well and yet Prompto was holding back, doing only what was needed to help Noctis. It didn't take long to finish and then Prompto lifted Noctis' limp body, rearranging the pillows before settling him under the covers and curling around him, practically purring.

Harry got up and sent a gentle cleaning spell at them both, spelling their shirts back on them. He then went into the kitchen and prepared an iron rich meal for when Noctis woke. It was rare, to find a willing donor that was so compatible and Prompto was going to be feeling very territorial for a while. It would also help keep Prompto from over feeding from him at least. Noctis would slowly become more and more attuned to Prompto's needs, able to instantly know when he needed to feed. Thankfully Noctis was magical himself, and obviously stubborn, that would keep him from being consumed by the bond. That was always the risk with a permanent, willing, donor and why he was going to stay.

He was happy that Noctis had accepted Prompto's heritage without any hesitation, even he had been surprised by how easily it had all gone. Noctis had shown no fear for himself, but for his friend. Part of him wondered how Lucis would react to an Immortal King and his Consort…he may be getting ahead of himself a little, time would tell.

He left the apartment, removing the magic that kept everyone else out, but in a way that wouldn't have them all converging on it immediately. The boys needed their sleep. He made his way back to the Argentum home to settle into the room he used when he visited. He would check on them tomorrow, this close he would know if Prompto needed him sooner.

TBC…

Teenagers, rushing into things without thinking. Noctis probably shouldn't have volunteered so quickly but Prince or not he is a teenager who is worried for his best friend.
