The Black Book - AU - Locked to seaweed_writes

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.

Comments

"Earlier today... Greg asked if we were going to have more, especially since the house is big enough." He told Sherlock.

"Maybe... I wouldn't mind another." He admitted to his mate.

John smiled shyly at him and put his mate's hand on his expanded belly.

[seaweed_writes]

The kids were quiet this time, no kicking, but that didn't make it any less amazing that there were two children in there, growing bigger and getting ready to be born soon.

Sherlock kissed John softly, a smile on his face. "If that is what you want, my love, then that is what I shall give to you." He chuckled.

"But first, we have to get these two out of you and let you rest and heal and let us get used to having three small (and tiny) mouths to feed in a new house."

[ihadabadday]

John smiled at him and touched his hand. "We should think about names..." he said after a moment.

He was finding he didn't exactly mind being pregnant, or bringing life into the world. He ran a hand over his belly, humming softly.

Names...

[seaweed_writes]

Shit, things had been so crazy that they hadn't even thought of names, had they? Sherlock thought with a grin.

"I am a bit stumped, to be honest." He admitted. "We could always be boring and name them after our parents." Even after 600 years as a Vampire, he still remembered his parents names- his human parents. The last link back to who he was, so many lifetimes ago.

He quickly shook those maudlin thoughts out of his head.

"But I am up for other ideas if you have better ones."

[ihadabadday]

"What were your parents names?" He asked.

There were still things that he didn't know about his mate. And he was quite excited to learn things about him.

He smiled as he watched his mate. Knowing soon he would go get their eldest with that delicious dildo inside him. God he couldn't wait to fuck him. Or perhaps... An idea began to form in his mind. It would take time.

[seaweed_writes]

"Interestingly enough, Elizabeth and Thomas. They were common 600 years ago, and are still common now. " He chuckled, but then his smile faded. "If they had middle names, then they were lost to history, sadly. "

John had a bit of an interesting look in his eye, a strange gleam that made Sherlock curious.

"What are you thinking about, my love?" He asked with a curious smirk.

[ihadabadday]

John nodded and rubbed his belly once more. Elizabeth and Thomas.

"What about Elizabeth Irene and Thomas Scott?" He suggested.

Of course, once Sherlock processed his look, he paused and grinned. "I was thinking about that dildo still buried in your tight arse. And how it will move and bump in you while you pick William up. Or the idea of getting a beast to mount you."

[seaweed_writes]

Sherlock groaned loudly. Over the years, they'd talked about having a beast mount one or the other of them.. or having a bunch of Demons take their turns filling Sherlock's arse with their come. But it had never happened. William came along, and then he became their focus.

Sherlock did think about it once in a while, but he would never bring it up, because there never seemed to be a good time. Of course now with two more babies on the way, it seemed even less likely.

He moved on purpose, which made the dildo shift and sent a shiver of pleasure up his spine. "NNnng."

"I want you to watch while a beast mounts me and takes me and fills me." His voice was a low rumble.

[ihadabadday]

John smiled and nodded. "You'll be such a good boy while you're being bred. I might have to tie you to a breeding stand. To ensure you stay still."

He didn't touch himself or Sherlock. No. This was the fun part. Seeing how desperate he could make his mate.

"What would you like to try first? A hound? Or even a horse?"

[seaweed_writes]

Sherlock whimpered and wiggled, which just made the dildo move inside of him again. He wanted to be a good boy for John, he really did.

"Mmmf... yes... please, John... W-w-hen... can.... When can I do this for you.. make you. proud of me.. and take a hound for you?"

"Please.. tie me up. and do whatever you want with me, give me whatever animal you want to see inside of me. I will be your good boy and I will take it and you can be proud of me."

He was fighting hard to go under, he had go get William fairly soon. So he had to stay in the present.

[ihadabadday]

John moved forward a bit and kissed him softly. "I can't have you slipping under my love. You need to go pick up William." He said.

He then pulled back and got up himself to start to get dressed.

"So get your clothes on and maybe tonight you'll get a treat." He promised.

[seaweed_writes]

"I know. I'm sorry." Sherlock shook his head and started to dress himself as well, being careful not to move the dildo any more than he had to, but of course that mostly backfired, and he ended up pulling up his pants and trousers with a raging hard on.

"I can't wait to see what my treat may be." He joked, with a little wink. "I'll be sure to be good until then. Or.. do you want me to be bad?" SHerlock chuckled.

[ihadabadday]

John chuckled and then slapped his arse, right over where the dildo was embedded in him.

"Be as good or as bad as you want..." he grinned. He pressed on the dildo, moving it in a bit further.

[seaweed_writes]

"AHHHH!!!!" Sherlock cried out at the slap. Between the stinging pain of the slap and the quick movement of the dildo in and out, he was honestly surprise that he didn't come right there and then.

Of course John teasing him further was just making it worse.

"JOhhhhnnnnn...." He whimpered loudly, not even caring that he sounded desperate and pathetic. He needed to will this horrible hard on away.. or he needed to get rid of it another way, though there really wasn't time for that, sadly.

[ihadabadday]

John grinned and moved to unbutton Sherlock's trousers and take his cock out. "Can't have you messing up your trousers..."

He ran his hand over Sherlock's still covered arse before slapping it again. And again. Making sure to hit over the dildo.

"Such a pretty pet." He said with praise.

[seaweed_writes]

"Nnnngg..." Sherlock groaned when John pulled his length out.

"AAhhhhh... J-j-j-ohhnnnnn!!!" His cock twitched,leaking pre with each slap to his arse, the pleasure and pain and aching need all rolled together.

"H-h-hurry... p-p-please...." He pleaded.

[ihadabadday]

John began to stroke him as he kept slapping his arse. His gorgeous round arse.

"Look at your plush arse. It always seems to be begging for a cock sunk into it." He leaned in and licked a stripe up one arse cheek.

He tasted so good. So very good. He kept stroking his mate's cock as the slaps continued.

[seaweed_writes]

"MMmmfff.. Johhhhnnnn.." His voice was low and growly and more than a little desperate. He arched up and humped at the air, his whole body was rigid.
"Y-y-es... John.." He begged. Your cock, a dildo, any cock.."

He rocked harder and faster.. "S-s-so.. c-c-lose... m-m-ore..:

[ihadabadday]

"Come for me good boy..." he purred.

He slapped Sherlock's arse again. And again. He loved the red that it was turning. And the faint remains of his handprints.

John could feel himself grow hard, but he ignored it.

[seaweed_writes]

"Nnnnn... Johhhnn... JOOOHHHNNN!!!" Sherlock threw his head back and screamed to the ceiling. His body tensed, his cock twitched, and with a guttural cry he was coming, in thick hot ropes all over John's hand and wrist.

He moaned and thrust and rode through the orgasm, panting as he started to slow, and then with one last little pulse, he was done.. He leaned hard on John's shoulder, trying to catch his breath, still riding that last little bit of the high.

[ihadabadday]

John kissed his back. "Good boy." He whispered, "Now get dressed and go pick up William."

He pulled back and went to get a warm, wet flannel to clean himself up.

[seaweed_writes]

Sherlock was still panting when he leaned away from John. "W-what about you?" He asked as John got up to get the wet flannel. It was obvious that John had been enjoying it as well, but time was starting to run low.

[ihadabadday]

"I'll have you make it up to me later." He promised as he wiped his hand and wrist down.

And he did intend to have Sherlock make it up to him.

He dressed and went out into the kitchen to get dinner together.

[seaweed_writes]

"I will. " He chuckled while John dressed. He cleaned himself up and then re-dressed, being careful of the dildo that was still in his arse.

"Be careful in the kitchen." He said, kissing John deeply, then gathering his hooded coat and gloves to go get William.

Since he was only half Vampire, William could spend more time in the sun than his father could, though he still had to be careful, and he mostly stuck to hoodies and shady trees when they had recess outside.

With a wave of his hand, Sherlock was gone, in an interestingly bumpy taxi ride to go pick up William, and an equally bumpy ride back where he had to keep his legs crossed to avoid being quite embarrassed.

Perhaps, he thought, as they headed back to 221B, this hadn't been the best of ideas. Maybe he hadn't thought it through well enough.

[ihadabadday]

Things got a bit crazy after that.

The little family got moved into the new house and settled into their new routines.

John was rapidly approaching his eighth month of pregnancy. His mother was around more, and even Mycroft came around more.

He was browsing pet adoptions. Maybe once Elizabeth and Thomas were born...
