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 was trembling with that first touch, those words. It was easy to see why people swooned over Vampires. They certainly made wonderful lovers. They had a way with words and making one want. John whined and nodded.

"Please..." he shifted to pull off his trousers. John got onto his hands and knees, presenting his arse to Sherlock, tail moving out of the way.

[seaweed_writes]

"Fuck..." All Sherlock could do was watch John undress and climb up on his hands and knees. His cock, hot and full, was long enough that it almost touched the sheets under him. His balls hung low as well, dark between his legs.

It was a wonder that he wasn't coming right now.

"Fuck, John." He repeated. "You have absolutely no idea how fucking hot you are, do you? Look at you, hard and dripping onto my sheets, ready for me." He gulped, shifting himself in his trousers in a vain hope of trying to stop himself from coming in his trousers from looking at this feast in front of him.

"You really have no idea."

[ihadabadday]

John honestly had no idea. No one had praised his looks like this. He figured he was attractive enough to at least land some of the people and creatures he had slept with.

"Sherlock... Please. I need you. Please. I don't want to wait anymore. Please fuck me." He begged. John didn't want to tear Sherlock's sheets, but oh... He felt like he could pop off at any moment.

[seaweed_writes]

"Johnnnnn.." It was as much of a moan as it was his name. He almost jumped off the bed, ripping his shirt off, not caring that buttons went plinking across the room. He threw the now worthless shirt on the floor. He kicked his shoes off, then went to work on his trousers, tugging them down, taking his pants down with them. He was already hard. Finally freeing himself from the confines of his trousers made him sigh happily.

He so much wanted to just push in and take him, but he promised that he would finger John first, so he would know what it felt like. Sherlock went to his dresser and pulled out the lube- he didn't use it often, once in a while when he was pent up and needed release.

Now that he had John, he knew that he was going to need a lot more.

"John. You need to relax when I push in. I know you've take big cocks, but I'm sure that you need to stretch. I assume that it's been a while." Sherlock kneeled behind John. He had the intention of pressing a finger inside, and instead, he pulled John's arse cheeks apart.

And licked.

[ihadabadday]

John screamed when he felt that tongue against his hole. Oh! No one had ever done that before. He pressed his face against the bed, sobbing. It was... So intense, so intimate. Sherlock was amazing.

His cock was hard and dripping. He vaguely pondered making a mold of it for Sherlock, for use whenever he wanted.

[seaweed_writes]

Sherlock actually pulled back in surprise. He hadn't expected that intense of a reaction. "No one.. had ever done that to you, have they?" He asked. "Do you... like it?"

Even though he asked the question, he was already leaning back in before John could answer, licking a strip from his perineum , across his hole, and up the top of his arse, then back down again.

He was sweaty and musky and surprisingly had the slight taste of brimstone.

It was PERFECT.

[ihadabadday]

John shook his head. "No... Never." He gasped. It was so intimate and it made his head spin and spin. He whimpered and pushed his hips back.

So needy. So desperate. He ached and wanted. These feelings that Sherlock was giving him. It felt like he was floating. Soaring. He whined.

"Please. More..." his tail moved to swipe through Sherlock's hair, trying to press him closer.

[seaweed_writes]

"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.
