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.

"Of course." He would give John anything, everything.

Sherlock licked another stripe, but this time he held it at the tight little pucker. While his hands held John's arse cheeks open, he pressed his tongue against the hole. At first, it didn't want to give, but after pressing in and relaxing a couple of times, John started to relax, and Sherlock felt the muscles open.

He took the opportunity to push forward and press his tongue inside of John. "Ohhhhh..."

[ihadabadday]

Another shout tore from him and he rocked back eagerly. More. John could hardly believe this was happening. He sobbed against the bed, trembling. Oh....

"Sherlock." He gasped, "Please... Don't tease me."

He had so many creatures of the course of his life. But right now. With Sherlock. It was perfect.

[seaweed_writes]

He gave John one last lick before moving away. "Do you want me to use my fingers first, or do you just want me to just fuck you right now?" He asked. John looked like he was wrecked, he was already far gone. His massive cock also leaked massive amounts of precome on his sheets. It looked like it was about as much come as he would have after a round of sex.

And that was just precome.

How in the hell much come had John emptied into him last night?

Now, he really wanted to know.

[ihadabadday]

John sobbed. "Anything. Both. I don't care." He admitted. He shifted and twisted and sobbed. Oh. He wanted anything inside him.

"Please. Anything. I'll fuck anything you want." He begged. John's head was spinning and he felt heavy and desperate.

[seaweed_writes]

There would be time to gently finger John another time, some time when maybe they took it a bit slower. For now, he just wanted to help John and let him feel the pleasure of someone being inside of him, making love instead of just fucking him wantonly.

"Alright, John. Alright." He tried to calm John down by rubbing at his back. When John calmed a bit, he leaned back and used plenty of lube on his cock. He got up onto his knees to align himself with John. He opened John's cheeks with one hand, and used his other hand to guide his cock to JOhn's now open and wet hole.

"John.. just relax. I will never hurt you. Never." He said, as he pushed in with a soft grunt.

[ihadabadday]

John gasped when Sherlock pushed into him. He was cold, the difference between their bodies startling. He moaned and pushed back.

His head was spinning with ideas. Ideas of what Sherlock could do. What he could do. All of it. All of it and so much more. He whimpered and shifted a bit. But soon he calmed and took a deep breath.

No doubt Sherlock would start moving soon and it would send him spiralling.

[seaweed_writes]

He often forgot that his body wasn't 37 degrees like a normal humans. And being a demon, whose body was slightly hotter than normal human's it made for a bit of a shock for both of them. Last night, Sherlock had been so surprised by the size, that he hadn't even been thinking about the heat.

But now, it was all that he could think of. John was hot and wet and tight around him. Even though he had taken a Minotaur, whose cock would have been even larger than John's, he was still tight. He had no idea how, but he didn't care. He felt fucking amazing.

Sherlock was slow, he wanted to remind John that this was making love, not fucking. He wasn't taking, he was giving.

And when he finally bottomed out inside of John, he groaned, putting his hands on John's back to steady himself. He didn't realize how much he was shaking with the effort.

"Tell me when you are ready to move, John. Feel free to touch yourself any time you want. I won't hold you back."

[ihadabadday]

John was shaking as he slowly adjusted to the feeling of that cold length inside him. He took a deep breath, groaning. Sherlock wasn't the largest he ever had, but it felt so good. So calming.

He relaxed his wings and his tail wrapped around Sherlock's arm, keeping him close. So close. He never had anything so gentle and loving. He moaned and shifted a bit. He was used to the intrusion stretching him out.

"Y.. You can move. Please... I need you Sherlock." He begged.

[seaweed_writes]

"You have me, John. Always. We are bonded now." Sherlock leaned down and licked and nibbled at the sweaty skin on John's back. He wasn't surprised that his sweat had the faint smell of brimstone and ash, like he had tasted before. He found that he loved it, and licked a long stripe up John's back, then breathed his cool breath over it, making John's demon skin shiver and goosebump.

When Sherlock finally did start, it was glacially slow, pulling out until only his head remained, and then pushing back with equal calm and evenness. He did this a few times before he sped up the pace, but only slightly. He was determine to make John understand what lovemaking should be- not what he had gotten before.

"You're so hot around me, Being inside of you is like sticking your hand in a warm oven, you are surrounded by the heat.. "Sherlock whispered, still working on John's back while the thrust in and out, in and out.

[ihadabadday]

He sobbed incoherently when Sherlock pulled out. No no! But he then cried out when that length was pushed back into his hot body.

John pressed his face into the bed, crying out. Oh. Oh.

This was so different than many of the other times he'd had sex. This wasn't soft. But it was loving and comforting. It was... he trembled and sobbed.

It felt so good. To be owned in this manner.

[seaweed_writes]

Sherlock paused for a moment, leaning down to put a steadying hand on John's shoulder. He was worried at how John was trembling and sobbing. Was he doing something wrong? Was he hitting some sensitive spot inside of him? Should he had been stretched before?

"John?" He asked, ready to pull out in a moment, if something was going wrong. "Do.. I need to stop? Is something wrong?"

[ihadabadday]

He shook his head. "N.. No. It just feels so good." He hiccuped, "don't stop. Please. Just keep moving in and out of me. Please...."

His head was spinning. It felt good. So very good and he wanted to keep it going. More and more. He wanted to feel Sherlock lose control inside him.

[seaweed_writes]

"Okay, okay. I will. " Sherlock nibbled just enough to bring up two little dots of blood. He licked the blood up then blew his cool breath on his neck again.

"I want to come inside of you, John." He said, as he started back up, going a bit faster and harder than before. "I want you to feel me spilling inside of you while you stroke that enormous cock of yours and make an absolute mess on my bed."

He grunted, speeding up again. "Look at the bed, the sheets are already ruined. You leak more than I come. And when you do come, you are going to flood this bed sheet with yourself because you have so much inside of those huge bollocks. I felt them empty into me last night.."

[ihadabadday]

John was losing control. He wanted Sherlock to fill him, give him his seed. He sobbed and pushed back. "Please. Come in me. Fill me. Please. I want you to fill me so."

Part of him did want to be impregnated by Sherlock. What brilliant children they would have.

He barely paid any attention to his leaking cock as the vampire moved in and out. Claiming him. Owning him.

[seaweed_writes]

What Sherlock did next was total instinct. He didn't even think about what he was doing. He just did it, and when he did, he lost, he was gone.

While Sherlock was fucking John, he leaned down to the pulse point on John's neck..

And he bit.

Even though he had just fed the evening before, less than 12 hours ago, feeding again from John while he was rogering him sent him into a frenzy.

He started to thrust hard and fast, buggering John so hard that the bed was shaking under them. He continued to suck on John's neck, each pulse of John's heart gave him another taste of blood.

Sherlock was totally gone- he couldn't speak or do anything but breed and fuck and take and oh it only took him a few hard thrusts, hard enough to move John forward before he yelled out and slammed into John as deep as he could go, spilling his seed inside of the half demon under him.

[ihadabadday]

John cried out at the bite. And the harder fucking that came after it. Oh! Oh! This was amazing. Wonderful. He was spiralling down and down, heading towards his release.

The way Sherlock was moving in him. It was almost like he was being bred by this vampire. His head spun, but he found he wanted that. To be bred and bred. He did want a child with this vampire.

But it was Sherlock coming inside him that set him off. John shouted as he climaxed.

[seaweed_writes]

It seemed like ages before Sherlock finally made one last thrust, and then collapsed on top of John, flopping onto his back, still semi-hard inside of him, and leaking the last few dribbles of his come.

It took him a moment to realize that John was still climaxing underneath him, shaking and making grunting noises and totally ruining his sheets with what looked liked liters of his come. He had no idea how much it really was, but it just amazed him to see how much seed the man had. If he had wanted to impregnate someone- if he was even able to, then it would only take one time, with as much semen as he had.

And all of that had gone inside of him last night.

"John." He panted while John's orgasm, and his flood of come, slower and then finally stopped.

[ihadabadday]

John raised his head and looked over his shoulder at Sherlock. "Hm?"

He was wrecked and it was an amazing feeling. He loved every moment of it and wanted to do it again. He let out a breath and shifted back to his human form. He knew Sherlock preferred his true form. But sometimes the wings just got in the way of cuddling.

"Sorry I wrecked your sheets." He said in reference to the claw marks in them.

[seaweed_writes]

Even though there was very little size difference between his human an demon forms- Sherlock wondered if there were any demons shorter than John, there was still a bit of a shape difference, and as John shifted, Sherlock's now soft cock naturally fell out of him, bringing another trickle of come to the already soaked sheets. Of course he preferred John in his true form, but he didn't mention it.

Sherlock chuckled and shook his head. "Between the amount of come that you spill, and your claws, I think we are going to have to figure out something to do about the bed." He really wasn't all that worried about it. Sure, they had been nice, high count sheets (that now look like a tiger had been on them) but the sex had been bloody fucking amazing, and he knew it was going to happen again. He had no idea yet what the solution was, but he'd figure something out.

"We really can't cuddle until we change the sheets, unless you want to get permanently stuck to them by your own semen." he laughed and kissed John, then- reluctantly- got off the bed. "And we both need a shower, I think."

[ihadabadday]

He huffed. "Fine." John got off the bed and stretched. He made his way to the bathroom and started the water.

John got in the shower, letting the warmth pour down over him. He let out a breath and reached up to rub his injured shoulder. It was the one part of him that he couldn't glamour. The arrow that had struck him had been spelled. It wasn't white magic. But it still injured and maimed. It was only thanks to his nature that he survived the impact.

He began to wash up, taking a moment to wash Sherlock's seed out of himself. He shuddered at the feeling of the water in him.

[seaweed_writes]

Sherlock frowned at the huff. Had he said something wrong? It was true, there was no good place for even one person to lay, much less two, with the mess that they had made together. Okay, it was mostly John, but he had helped.

He sighed and let John go, then gathered up the sheets- happt to see that by some miracle nothing had gotten to the mattress, and threw them in the larger bin in the kitchen. They wouldn't have fit in the small bin in the bedroom.

He was sore and sticky, but John had left in a bit of a huff, so he decided to let John get a shower by himself. Instead he busied himself with finding and putting on his second best sheets. John didn't need to know that those had been his favorite, though Sherlock still didn't regret a moment.

Well, up until whatever he said to make John go away in a huff.

[ihadabadday]

John finished his shower and stepped out. He began to dry off. Once he was dry, he left the bathroom and returned to the bedroom.

"I owe you a new pair of sheets." John said sheepishly.

He loved over and kissed him slowly. "I enjoyed every moment of it. Truly."

[seaweed_writes]

Sherlock's shoulder visibly slumped once John came back into the room and kissed him. He thought that he'd dome something wrong- again, and he wasn't even sure what. Had John been mad at him about complaining (albeit rather jokingly) about the sheets? They had been his favorite, and rather expensive, but he wouldn't tell John that.

He kissed back eagerly, running his hands up and down the man's back. "And I as well." He replied, his voice low. And then with a flash, he remembered. He went around so he could see where he had bit at John's neck. The two little puncture wounds were already scabbed over. He must not have drank too much.

And he slumped even more with relief at that. He was going to have to be careful. He knew that biting would never turn a full demon, but John was half human, and had no idea what might happen. The last thing Sherlock wanted was for John to share this curse with him. He already had enough persecution and prejudice being a half demon. He had no idea what a half demon vampire would be like, but Sherlock wasn't' sure that he ever wanted to know.

[ihadabadday]

John shivered when he felt those hands roam his back. The cool of those hands were such a contrast of his own skin. He let out a breath. His eyes looked down at the soft cock that had been inside him.

He licked his lips and then looked back up at Sherlock.

"Pick out the sheets and I will buy them for you." He said.

[seaweed_writes]

Those eyes roaming his body, those warm hands on his skin. His cock gave a sympathetic twitch when Sherlock saw John staring. As much as he wanted to, even as a vampire, he had a refractory period, though he had to admit it was shorter than most humans of the age that he was when he turned.

He was turned as what would have been a young man in this modern era, but the fact that he had just reached 30 when he was turned in the 1600's was a feat- the average life expectancy in his time was only about 35 years. He had already been in what would have been the twilight of his life.

And now, he was, functionally, immortal, and bonded with a half demon that he had no idea the life span of.

He could only hope that if John died, he could find a way to die with him. But that, hopefully was hundreds of years off, if not even more.

Sherlock shook himself out of those morbid thoughts and back to John.

"It's really okay, John. I can get more sheets. We will most likely have to find some sort of thick plastic undersheet so nothing will leak onto the mattress and it will be somewhat protected. And we should probably start buying cheaper sheets in bulk." He smiled, hoping that he hadn't offended John.

He unfortunately seemed to be good at that.
