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.

"Sherlock shook his head. "M's network is vast, much more vast than mine. There is no where that we could hide that he couldn't find me. And when he did, he would most likely kill you, and maybe me as well." He sighed, his shoulders sagged. They were trapped in London now.

He finally opened his eyes, turning his head and shoulders enough to look over his shoulder at John. "I don't regret one single moment of the time that we have been together." He said, and it was totally true. He wouldn't give up John for an Old One, or a First Blood, or anyone else.

"Mmmm." Sherlock leaned his head back and exposing his neck, and making a soft sound when John showed his true form. He relaxed in those strong arms, wrapped in the leathery wings.

[ihadabadday]

John kept his wings tight around Sherlock. He just wanted to hold the man close. Remain in this flat forever.

"Will you feed from me? Please?" He asked.

He wanted to be... Loved. He wanted to know it, hear it. He ran a hand through those mussed curls. He pressed his face into Sherlock's neck, trying to stave off tears.

He wanted to keep them safe. And right now, safe was bending to the will of those who made them.

[seaweed_writes]

Sherlock really wasn't feeling in a very dominant mood right now. He would have much rather been taken care of. But he would never deny John anything that he could readily give him.

So Sherlock rolled over, and gently moved John's head back so he could reach his neck. He licked at his lover's neck a couple of times, tasting him and finding just the right point. ...

Ah. There it is.

He bit down, immediately that wonderful coppery taste of blood hit his tongue, and his eyes glowed red. He drank deep, flicking his tongue around the wounds to keep them from coagulating as he drank his fill, his fangs still stuck the couple of centimeters in the pulse-point of John's skin.

"Mmmm.. Perfect." He murmured.

[ihadabadday]

John gasped when those fangs pierced his skin. Oh... He closed his eyes, relaxing into the feeling of this. It was so intimate and it made John's heart nearly burst. Oh how he loved these moments. He cherished them and hid them away inside his heart.

"I love you." He told Sherlock, "With all that I am."

He didn't care if anyone thought their mating was wrong, or a way to an end. No. He didn't care at all. The only person who he wanted to care was Sherlock.

[seaweed_writes]

"John. Please." He asked softly while he was still drinking from his lover neck. "I love you. I need you. Please." He just wanted to forget about the world and the politics and all of the bullshit that was everywhere but in this room, and taste John on his lips and feel his lover inside of him.

The intimacy of being joined, fang to skin, was only second to the intimacy of being connected bodily, one being inside the other. Sherlock had been the more dominant once more often than not in the last 2 months, and there had still not been any hint of a breeding yet. They both knew it was a long shot, but they both wanted it to happen.

But tonight, Sherlock just needed to be taken and used so he could pretend the rest of the day hadn't happened, or at least forget it had, for a short time.

[ihadabadday]

"Of course. Anything for you." He told him. John shivered when he felt those fangs pull from his neck. The blonde groaned and told them so Sherlock was below him. He gave a breath and stretched out his wings.

"I want you to get undressed." He said softly, "Slowly. Like you're putting on a show for me. And then I'm going to get on my knees for you and swallow your gorgeous cock down while I stretch your tight hole out. You can hang onto my horns if you need."

He then got off Sherlock and off the bed. John removed his trousers and red pants. His giant cock was only half hard at the moment.

[seaweed_writes]

"Nnnng.." It was all that he was able to say. He loved it so much when John told him what to do. Oh bloody buggering hell, even when he was only half hard, he was still bigger than Sherlock was hard. He quickly scrambled off the bed, then remembered that he needed to do this slowly.

So he started with his shoes. He bent over so that his arse was facing John while he unlaced his shoes, and then toed out of them, stepping away behind them. His socks came next, still bending over and showing John his arse, still covered by his trousers.

When those were done, he put them in his shoes, then turned and turned back towards John, so he could watch him start to unbutton his shirt, from the top down.

[ihadabadday]

John sat on the bed and stared at his mate. His mate. His gorgeous, brilliant mate. He let out a breath. The mate that would father their children. It would happen. What brilliant children they would have.

His eyes took in every movement, every moment. What a lucky one he was. To have a mate willing to put on such a show for him.

[seaweed_writes]

Sherlock tried not to stare, but.. now couldn't he? God, he loved John in his true form, the horns to hold on to, the wings that wrap around him, the cock that stretched him open, the tail that gently caressed him. He was perfect, utterly perfect, just like he had told John that first time they entered 221B, and Sherlock saw him for the first time as he was meant to be.

When the last button was undone, he shrugged out of the shirt, then slowly pulled off the plain white tshirt that he had on under that. That left him naked from the waist up. He shivered slightly, with the clouds outside the room had dropped in temperature a bit. He was cold natured and didn't mind as much, but perpetually hot John probably felt it more than he.

But they would be heating up soon enough, he thought with a smile, as he slowly,. ever so slowly unbuckled his belt.

[ihadabadday]

"You're gorgeous for me. My perfect mate. You're going to give me, us, such pretty children. They're going to be brilliant like you are." He said in a rush. His cock was fully hard and he shifted a bit, putting it on display for Sherlock.

"I want you to give me such pretty children. Fill me with so much of your seed that it has no choice but to catch. And when I'm round and heavy with our child, I'm going to fuck you. You'll feel my swollen belly against your body as I spear you on my cock."

He couldn't help it, he ran a hand over his belly, almost protectively.

He wanted to fuck Sherlock until the vampire gave him everything. "You'll suck my cock and drink from my breasts and my neck. You'll never need anyone else."

[seaweed_writes]

"Mmmm.. fuuuuck." Sherlock had to force himself to slow back down again. Oh bloody fuck did he want that, to breed John and watch him grow round with the product of their love, and then let John fuck him while he's huge and heavy and full of their child.

"Nnng.. John.. p-p-please..." just listening to that was almost too much. He sighed in relief when he undid the flies of his trousers and pushed them down, almost releasing his cock- only a thin layer of the soft fabric of his pants stood between them. He kicked his trousers off and his pants went a moment later, showing him fully hard, flushed and already dripping.

"S-s-how me how you will fuck me.. when.. when I impregnate you.. please, John.. I need you."

[ihadabadday]

John moved and got on his knees in front of Sherlock. He licked his lips and then leaned in, taking the head of that dripping cock in his mouth.

He groaned and moved his hand back to tease and brush over Sherlock's hole. He couldn't impregnate Sherlock, but he would show the vampire how he needed to be fucked.

He wanted to ride Sherlock's cock when he was travis, his milk swollen breasts bouncing up and down.

[seaweed_writes]

"Ohhh... fuuuuuck." Sherlock did indeed grab onto John's horns. They were short and stocky, and there was not a lot to hold onto, so he compromised and kept his left hand on John's right horn, and put his dominant right hand in John's hair, which he held on tight.

He knew he wasn't going to last long, but John hadn't said that he was going to let him come while he sucked his cock, so he bit at his lip and tried to will his body to not go off like a rocket.

Which was hard when you had someone like John flicking his slightly forked tongue over the tip of his glans.

[ihadabadday]

He pulled off Sherlock as he pushed two fingers into thevampire.

"You're so tight. I should make you wear a plug all the time, so I can fuck you whenever I want. Or rent you out." He teased.

"Would you like to satisfy a hoarder of demons with bigger cocks than my own? If you were human, they'd rip you in two."

[seaweed_writes]

"Nnnng...." He was tight, he hadn't been fucked by John in over a week, and that had been in his human form. It'd been much longer since he coaxed out John's demon form to fuck him.

Just the thought of wearing a plug, being so full of John's demon come that despite the plug it would STILL leak out made him groan and shiver. "Yy-yes.. please.." He begged.. "You... can watch me... watch them t-t-take me... Then.. use me to make sure that it's your come and not theirs inside of me.. Then p-plug me up, so your seed won't go anywhere.. Please..."

He wasn't even sure what he was begging for now.. something.. ANYTHING

[ihadabadday]

John nuzzled his hard cock, smiling. "Anything that you want my love. Anything at all." He then added a third finger into Sherlock.

"Hands and claws and tentacles holding you down while cock after cock is stuffed into your abused arse. Or toys. Or tentacles. I bet you could fit ten in your hole."

[seaweed_writes]

"Ahhhh..." Another long, sticky dribble of precome leaked from his cock and it twitched, throbbing against John's skin.

Having three thick demon fingers, complete with claws inside your arse was something he had to get used to. John has to be careful, but Sherlock trusted him utterly, and John had never, ever hurt him, intentionally or accidentally- that had been something they had talked about the night they bonded, but it had never happened in the months that they had been together.

God, thinking about cocks and tentacles and who knew what else shoved inside of him made Sherlock groan, and another fat drop of precome formed at his slit. "Yessss.." He hissed out. "Pp-please John. Let me be your fuck toy... I.. I am yours.. body and soul..." Even though he technically didn't have one of the latter.

[ihadabadday]

John pulled his fingers out and stared up at Sherlock. "Bend over the bed." He ordered.

He loved these moments, when all they could think about was their pleasure. The give and the take.

Nothing but the two of them mattered. Not mother, not sire, nothing. It was just them.

[seaweed_writes]

Sherlock knew what was coming, he did, and yet, he still always felt that small flash of disappointment when John pulled his fingers out of him. But was always a fleeting feeling, because something much, much larger was about to fill him to the brim.

He walked over to the bed and leaned over it, his knees on the floor and his arse on the end of the bed, his body on the bed itself, his hard, leaking cock was trapped under his body.

"Please John." He begged. "Please plug me, so you can fuck me again and again and I will always be leaking your come out of me." It was a fairly new acquisition, they were getting toys slowly, one at a time, while they figured out what the liked and what they didn't, still feeling each other out while in the bedroom, as they had only been together 2 months. They hadn't even had a chance to use the plug yet. Because both of them were pretty much size queens, they found about the largest plug they could, though it was still not as wide as John's Demon cock. He hoped it would hold enough of his seed inside.

He hoped he was about to find out.

[ihadabadday]

John got up, though a little shaky. Without a word, he went to the closet to retrieve the plug and some lube. He brought it back to the bed before setting it down next to Sherlock.

"Your arse is gorgeous." He whispered as he ran his hands over it.

He picked up the lube and opened it, spreading some over himself and then around Sherlock's hole.

[seaweed_writes]

Sherlock licked his lips when John put the plug down next to him. It was a very basic plug, black, in an almost diamond shaped design. It had a very wide base, then a short area where it was much skinnier, then it flared back out to about as wide as the base, and then it tapered to a rounded point. It didn't need to be long, it just needed to be wide to keep Sherlock nice and stretched.

And it was.

He moaned and closed his eyes. Sherlock loved it when John talked dirty to him, but even more when he praised him at the same time.

"Ahhhh!" The lube was cold at first, it was a bit of a jolt to the very sensitive nerves around his opening> But with a bit of time and John warming it with his much warmer body temperature, it became quite nice quite quickly.

[ihadabadday]

He smiled and then pulled his fingers away. John loved seeing Sherlock like this. So needy. So everything. He kissed the small of his back, nipping with his own fangs.

John straightened as he pulled back and grinned. He positioned the tip of his cock at Sherlock's hole and began to push in. And in.

He didn't stop until he was entirely seated in the vampire.

[seaweed_writes]

"Ahhhhhh!!" Even after two months of being his mate, even with three fingers of stretching, it still hurt, it still stretched and burned and stung.

And he loved every single second of it.

He shut his eyes tight, moisture pricked at the corners of his eyes. He desperately held onto the sheets under him and tried desperately to rut against the sheets, but it wasn't enough friction to actually get himself off.

The pain ramped up and up and up and just when he was at the threshold, John was fully inside of him, and the pain and endorphin started to switch to pleasure, intense and overwhelming.

"M-m-ove... god.. fuck.. move.. please.." He begged the demon.

[ihadabadday]

John smoothed his hands over Sherlock's hips as his tail wrapped around the man's thigh. "Look at you, so desperate." He cooed, "what do you need?"

He knew. Oh he knew. He wanted to hear it though. He wanted to push and push and then shatter Sherlock. So all that they both knew was one another and nothing else. No one trying to control them, use them as pawns.

[seaweed_writes]

"Joooooohnnn..." He whined, not even sure if he could get anything else out than that. He knew that John knew what he needed, and yet, he was still being made to say it.

"F-f-uck me.. John... I need you... P-please..." He shivered at the warm tail around his thigh. It was both grounding and erotic at the same time.

"I... need you... I need you to fuck me and stroke me.. and l-let me come... " The plea ended with a loud groan and he tried to buck at the sheets again, but it was no use.
