He was lucky with his expertise he was able to find a job relatively quickly in a field he was familiar with. John looked down at his mobile as the alert came through. Christ. It was going to take him at least twenty minutes, if he was lucky, to get to the scene. But, he packed his things into the case and headed out.

He had been in Afghanistan for five years. First as a medic, then a doctor, and finally a hunter. He still was a doctor, but he had been assigned to an elite unit in the desert. Part of him felt a bit odd about all of it. But he didn't quite mind.

He made sure he had everything before he left.

He heard the annoyed voices, before he saw anyone as he entered the room.

"Oi. Who're you?" A man with two days of stubble and mussed black hair asked.

John paused and looked him over before his eyes landed on the gentleman in the suit with salt and pepper hair. There he was. "DI Lestrade? I'm Doctor John Watson, the new Occult Specialist, I just started last month." He gave him a smile, wanting to be nice, but not too friendly. People got jumpy around the occult. He saw it all the time in Afghanistan, and even here in London.

John pulled back from the kiss and smiled at the vampire. "If you don't mind, I'm going to shift back..." but before he did that, he stretched his wings out, making a pleased noise.

He even let his tail stretch. God what a feeling.

He stepped back and let his power slide over him, his horns and wings and tail fading. Now he was just a shirtless human.

[seaweed_writes]

If Sherlock had to be honest, he actually preferred John's true form. He knew that it took a bit of exertion to keep himself looking like a human, and he wondered why he would want to look like those lowly creatures.

Never mind that he had been one of those 'lowly creatures', though that was over 400 years ago. He'd had plenty of time to get over that.

God, the power that lay beneath that skin, under those small but powerful wings and the sharp mind that lie under those horns.

"You.... don't have to... you know." he said, hating how stupid he sounded yet again. "Be.. human. If you want to be your true self around me..." his voice trailed off.

[ihadabadday]

John knelt down and touched his cheeks, now blunt human fingers running over the smooth skin. "I don't know the coming and goings of people in your flat."

He leaned into kiss Sherlock again, using a bit of teeth into it. The blonde pulled back and smiled.

"We have many years. But I don't want to wait..." he said. John was referring to sex.

[seaweed_writes]

“There are only three regular visitors to my flat. “ Sherlock said. You’ve already met Lestrade. My landlady, Mrs. Hudson occasionally bothers me, and very rarely, Mycroft.”

Sherlock hissed at the use of teeth and nipped back, barely controlling himself from biting down. But he held back.

Of course he knew that John was referring to sex. He had lived 400 years. He knew almost all there was about sex by now.

“Well then.” Sherlock grinned, pulling them both to their feet and taking both of Johns hands. “Let’s not wait.” Without another word he led John back towards his bedroom.

[ihadabadday]

As he followed Sherlock, he let the glamour fade naturally, showing his true form once more. Since Sherlock seemed to like it more.

Once in the bedroom, John sat on the bed. He grinned at the vampire and tugged him down to kiss him.

He ran his hands to Sherlock's hips and squeezed. The power that was under those clothes. He wanted the bruises.

[seaweed_writes]

To Sherlock, it was odious that anyone had to hide their true selves. He had no qualms of letting everyone know that he was a vampire, even if it brought him more persecution and shaming. And it was the same with John. He didn't want John to feel like he had to hide behind a facade for him.

Besides, he wondered what it felt like to be wrapped in those wings, and how sensitive John was with those horns and that tail.

Sherlock was standing over the half demon,. who was sitting on the edge of the bed, his feet still on the floor. At least John only had his trousers on. Did he wear pants, Sherlock wondered? How well endowed were half demons anyways? He had to admit that he was a bit of a size queen- the bigger the better.

"Nnng.. Now who's the eager one?" Sherlock all but purred when John squeezed at his hips. He didn't mind the awkward angle of leaning down to kiss John. He nibbled on the man's neck, so close to drawing blood, but he stopped just short. Exchanging blood was a sacred ritual and had to be done a certain way, and only when both participants waned to be permanently bonded.

Not yet, he thought. But soon, he could at least hope.

[ihadabadday]

"Not yet." John whispered, "But soon..." It was obvious what the vampire wanted. He wanted it too. To feel those teeth sink into his neck or leg or the vein above his heart. He shivered.

He moved his hands and began to unbutton the shirt that Sherlock wore. It was well tailored and the color complimented the vampire.

He was hard in his trousers, his cock pressing uncomfortably against the zipper of the denim he wore.

[seaweed_writes]

Sherlock smiled. Of course John would love the blood red shirt that he wore. But right now, it was just getting in the way of being naked with John. He worked the top buttons down while John was moving from the bottom up. He shrugged it off his shoulder onto the floor.

A quick look at John made Sherlock groan. Fuck, John looked huge under those trousers.. "Damnit. John." He was a size queen, but he wasn't sure if he could take it..

He intended to find out.

"John." He groaned. He leaned down and ground down into John's lap. "You have no idea whar you do to me, do you?"

[ihadabadday]

John groaned when those hips ground against his. He shivered and ran his hands through those gorgeous curls. Everything about the vampire was gorgeous.

He wanted him. He could feel the vampire's want pressing against him.

The half demon shifted and nuzzled his neck, kissing and nipping. God... he had never wanted so badly before. It was such a sensation. To want someone in this way.

"No. None... But you make me want. You make me want to submit. And I've never done that."

[seaweed_writes]

"I... need to see you." Sherlock pulled John up off the bed until he was standing again. Immediately, he started to work on John's trousers, undoing the belt and then undoing the zips. Without pausing, he tugged John's trousers down. Indeed, he wasn't wearing any pants, and Sherlock could see what had been hiding under those trousers.

"John.... fuck..." His eyes went wide.

[ihadabadday]

John flushed when Sherlock demanded. When he undressed him. He shifted from foot to foot. His tail curled around his upper thigh.

"I... I... Is it okay?" He asked in reference to his whole body.

He had scars and tattoos. He wasn't pristine. It made him more normal.

[seaweed_writes]

"John..." He looked the half demon over again. "Have you never seen another.. man before? You are.. huge." Sherlock gulped. God, how he wanted to have that in his mouth, or... well anywhere, really.

"Every part of you is perfect. I wasn't lying when I said that." Sherlock nibbled carefully at his neck, not using his fangs so he wouldn't draw blood. Every part of you. Every scar tells a story and every tattoo means something.

Sherlock ground down against John again, "You are perfect, and you are mine." He didn't even have to use the Thrall for that.

[ihadabadday]

He looked up, face heated. He shifted and smiled shyly at Sherlock. "I... I haven't been with many men. Mostly women." John admitted.

He gasped when he felt that mouth along his neck. Oh... Oh... he wanted. John grabbed Sherlock's shoulders, whimpering.

"Pl... Sherlock. I give you permission." He breathed. He wanted to give Sherlock all. He knew it was sudden, but it felt so right.

[seaweed_writes]

"Are.. you sure?" Sherlock asked, leaning his head back to look into John's eyes. "Do.. you know how this has to be done?" He took a deep breath.

"I have to bite you, and drink from you. I have to take a lot. If you were human, it would almost kill you. And when I am done, you will have to bite me, and drink from me as well. It is... a very.. sensual experience. " Sherlock licked at John's neck, right at his pulse point, right where he would bite.

"This will bond us for life, John. There is no going back, until one of us dies. And that will take a very long time. " He licked at John's neck again, his hand roaming over John's now bare arse cheeks.

"Tell me now, or I am going to bite you, and I am going to drain yo."

[ihadabadday]

John met his eyes, gaze unflinching. "I understand. I know what it means to blood bond."

He rocked his hips forward against Sherlock's. He had known the vampire for three days, he had killed for him. It was all okay.

"Do it Sherlock." He whimpered, "Please."

[seaweed_writes]

"Nnnng.." Sherlock rocked back. John was naked, and Sherlock still had his trousers and socks on. He wished that he had taken them off before that, but it was too late for that now, he couldn't wait another moment."

Sherlock rocked down into John's lap. He licked and nibbled at John's neck, tenderizing and wetting the skin. He reared back, his fangs glistening. With a small hiss, he bit down. His fangs easily tore through the skin, into the vessels underneath. His lips suctioned against John's skin, sucking the blood away into his mouth as soon as it pooled at the surface.

He drank eagerly, taking John's essence into himself.

[ihadabadday]

John cried out when Sherlock began to drink from his neck. Oh... He grabbed onto his hair, wanting to keep him close.

This feeling...

He was starting to feel light headed. But it was wonderful. He groaned, his erection pressing against Sherlock's hips. He wanted... he needed. Oh.

[seaweed_writes]

"Mmmmm.." The vibrations of his voice could be felt against John's skin.

And still he drank.

He knew how much he could drink from a human, but he didn't know about a half demon, so he had to be careful.

God, he wanted John to fuck him with that gigantic cock of his, but he couldn't stop this now. He had to keep drinking. He had to continue.

He started to rut against John, fucking at his lap while he continued to suckle at John, drinking more and more of his blood.

[ihadabadday]

John's hands dropped away from Sherlock's hair, groaning. His world was darkening a bit. But it felt so good.

"Sherlock..." he groaned.

His wings moved and surrounded Sherlock, keeping him close.

[seaweed_writes]

"Nnnnggggg..." The feeling of those wings surrounding him, it was.. intoxicating.

As much as Sherlock wanted to keep drinking, he could see that John was starting to fade. It was almost time to stop.

"John..." John was goring weak, and yet he could still feel that huge cock pressing against his painfully straining trousers.

He kept drinking for a few moments more, until John started to sway and have a hard time sitting up. And only then, finally, did Sherlock move his mouth away, licking at John's wound and cleaning the last of the blood that was trickling out.

"John... It's time.." He had to do it now, while the blood was still fresh and draining from his own neck if they wanted to blood bond. Sherlock rocked against John, desperate to come, but just simply rubbing inside his trousers wasn't enough.

[ihadabadday]

He looked at Sherlock and nodded. He could. He wanted to. "Sh... Sherlock..." John stammered. Everything was a bit fuzzy, but he wasn't going to pass out. No... There was so much to do. Sex to be had.

He licked his lips, focusing on the vampire in his lap.

It had been sudden, all of this. But it was okay. It felt right. All of it.

[seaweed_writes]

"John... You have to bite me. NOW." The saliva in Sherlock's mouth has anti coagulant properties, it could help to keep the two tiny wounds open, but only for a sort time. If John didn't bite him before they stopped bleeding, then he would Change. Humans would change into vampires, but he had no idea what would happen to John.

Sherlock leaned his head over, exposing his neck, even pointing out where John should bit. "Hurry. Bite me now, before it's too late. I need you to bite me."

[ihadabadday]

John nodded and leaned in. He kissed right over the pulse point and then bit down, his own fangs piercing the skin.

He shivered and then took a drink. This wasn't the first time he had blood. But never had it this way. It was such a different experience.

He kept his wings around Sherlock as he drank.

[seaweed_writes]

"Ahhhhh!!" His whole body went rigid, his eyes went wide, his pupils blew wide. Other than the vampire who had turned him 400 years ago, against his will, no vampire or demon or anything else had every drank his blood. He had no idea what it would feel like.

It was the most intense feeling that he had ever had. It felt like his whole body was being shocked by an electric current, but not in a bad way- in the best way.

There had been one little pinprick of pain, and then, everything was pleasure. He gasped and rocked down hard against John, his cock was rock hard and dripping inside his trousers. He felt safe in JOhn's wings, and he leaned in as close as he could, trying to touch every part of John that he could.

[ihadabadday]

John pulled back and pressed a kiss to the spot he bit. "Sherlock..." he whispered. He was so hard and so... So...

"I need you. Please. I need you." He begged, "I want you."

John tugged at Sherlock's trousers, wanting them off. He didn't want to hurt Sherlock with his claws.
