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 sobbed and shifted a bit. "You. I want you." And he did. He always did. He wanted to be with Sherlock and love him and cherish him and... And...

He shuddered and grabbed at the sheets. "Please... I want you."

[seaweed_writes]

Sherlock licked at John's ear. "You have me." He whispered softly. "You have me for the rest of our long lives." He adjusted himself until he was rubbing the head of his cock against John's entrance again.

"Is.. this what you want my love? My pregnant love, my gravid mate?"

[ihadabadday]

"Please... Yes..." he begged, "Please. I need it. I need you. Please...." John was lost in the pleasure, just focusing on it, what it felt like to have his mate inside him over and over. He shuddered and tried to pull Sherlock closer. Closer. Please.

"Yes. Sherlock. Please..."

[seaweed_writes]

"MMmmm.. Johnnnn.." It only took a few strokes to get himself hard, and then he was pushing in for a third time. Sherlock know that he wasn't going to have neat as much to give when it came to filling John, he just didn't have as much as the Demon could give, but that didn't mean that he couldn't make it feel really good.

This time though, he was slower about it. Less frantic fucking and more like making love, worshiping John while he moved in and out much slower than before.

[ihadabadday]

It was slow and it made his head spin. What a wonderful feeling. The sensation of Sherlock rocking in and out of him in this way. He moaned and just held on, letting himself take in every thrust, every touch.

He knew the next months were going to be hard on all of them. But in this moment, it was just the two of them, against the world, like they had promised.

[seaweed_writes]

"John, Johnnn.." Each time he pressed into his mate, he groaned the man's name, like a prayer. Slowly, he started to increase his speed and the power he put behind the thrusts, but it was still slower than it had been before, like he wanted to keep it going for as long as he could. He was quite aware that John still hadn't come yet, and he was working towards his third orgasm.

"Let me touch you... please, John. I want to hear you come apart under me." Fuck, the Demon was so sexy. He loved his lovers true form. Well, he loved everything about JOhn, really.

[ihadabadday]

John was spiralling down and down and he just couldn't hang on anymore. He felt like he was going to plummet down and down.

He moaned at the slow thrusts. Over and over. It was beautiful torture and he didn't want it any other way. John sobbed and clawed at the bed.

"Daddy..." he gasped, "Whatever you want, I'll give you whatever you want."

[seaweed_writes]

Sherlock hadn't expected for John to regress- not that he minded of course. But that did change his perspective.

It no long really became how many times could he get off. He was much more focused on what he could do for John. He was quite vulnerable when he was regressed. Of course Sherlock could take advantage of it., But he never had in all the time that they had been together, and he never, ever would
.
He would rather die first.

It was a little jarring to see John regressed, but still in his Demon form. The two just seemed to opposite. This was not the first time it happened, and he was sure that it wouldn't be the last either.

But Sherlock was going to make sure that John got the pleasure that he had been denied for so long tonight while Sherlock had taken his pleasure several times.

He was still thrusting himself inside of JOhn, but now it was very slow only to keep up his erection and make John feel good, not to get to the end.

"My good, good boy. I'm going to make you feel so good, for being such a wonderful boy tonight." And with that, Sherlock took his hand- the one that didn't have John's tail wrapped around it, held John's massive Demon cock- he couldn't even come close to getting his hand all the way around, and gave it a long, slow stroke.

[ihadabadday]

John loved his Daddy. He wanted to make him happy, make him proud. He shivered and pushed back, wanting to just please him.

"Daddy..." he moaned, "You feel so good in me."

He always did. The blonde moaned, clutching at the blankets under him.

But then that hand was on him. He gasped and pushed into it. No matter what, Daddy's hand always felt so good on him. He whimpered, feeling so close already.

[seaweed_writes]

"Mmmm." Sherlock hummed happily. "And you feel so good, all warm and tight around me." He punctuated it with a little thrust.
Sherlock leaned down, whispering in a low voice right next to John's ear.

"Be a good boy and come for me. I know you want to. You've been so helpful and sweet and good. And you deserve to come. Let go for Daddy."

As much as he wanted to use both hands to wrap around John's massive Demon cock, he had to keep one hand on his mate's hip to steady himself. He increased his thrusting, moving faster and harder, trying to encourage John to fall over the edge with him.

"Come on, my lovely. My John. Come with me.."

[ihadabadday]

That did him in. Daddy's urgings and touches.... He shouted into the pillow as he climaxed, his body tightening around the length inside him.

Oh.

His wonderful Daddy. He moaned and closed his eyes.

His head was spinning, but he felt good. So very good.

[seaweed_writes]

"Mmmmf.... good... boyyyyyy...." Sherlock praised John while he fucked John through his orgasm. He cried out and spilled inside of his lover, grunting softly and thrusting with each pulse.

It was shorter and not as intense, he was exhausted after coming multiple times, and he almost collapsed in a sweaty heap on top of John, stroking his hand through his lover's sandy hair and telling him how good he was and how good he did and how proud he was of him.

[ihadabadday]

John slumped under the vampire, groaning. He felt so heavy and just wanted to sleep.

But the bed was a mess.

He snuggled back, feeling his mate still buried in him. A feeling that he wanted to live in with forever.

John's tail dropped away from Sherlock's arm, giving the man full range of motion.

[seaweed_writes]

"Good boy. My good boy." Sherlock's voice was low and sleepy and slow. He really didn't feel like moving, despite the mess around them.

"We can shower in the morning." He murmured. He has his alarm to always go off 30 minutes before they had to wake William in the morning, so there would be time for a quick shower.

But he still roll off of John, mindful of the fact that he was pregnant, and they had to be very careful of that tiny, tiny life inside of him.

"Sleep now, my love. I love you so much."

[ihadabadday]

Time had gotten away from him. John had been in touch with the demon that had helped him deliver William. But neither he nor Sherlock had told their respective parents yet.

He was four months along and just starting to show. But he needed to call his mother. William was out at school and Sherlock had been summoned by his sire.

John sat down and took out his phone. He dialed his mother's number.

[seaweed_writes]

Time seemed to both fly and crawl at the same time. John had taken time off of work again, and was mostly at home, to make sure that their baby was safe. So far there hadn't been any scares, but there was still a long way to go.

***

Martha picked up the phone, looking at the ID by the number.

"Oh, John." She had been trying to call him John more. He had requested it many times, but it was hard for her to change how she'd called him for over 50 years.

"Nice to hear from you. I hope my grandson is well?"

[ihadabadday]

John put a hand on his flay belly and smiled softly when his mother answered.

"Hello Mum." He said.

"William is well. He's very excited."

[seaweed_writes]

"Well, that's good."There was a little bit of an awkward pause. Things were a lot better between them than when Sherlock and John met, but there were still times when they weren't sure what to talk about or what to say. There had been many years of strained relationships before.

"So." She said softy. "I assume that you have something to talk about?" Neither of them made superfluous phone calls, it just wasn't their way.

[ihadabadday]

It was refreshing, not to have to participate in small talk. He got enough of that during the day at William's school or at work.

"Mum, I'm pregnant." He told her.

Last time she had not had a favorable reaction. He wasn't sure how she would react this time.

[seaweed_writes]

There was a long pause, and then a soft "Oh." And then after another pause, a longer. "Oh!"

"Was this planned? You've waited a long time since William was born. I hope you are taking care of yourself. Remember last time you were on bed rest most of the time. What does William think? Is he excited about being a big brother?"

She could have asked more questions, but she finally ran out of breath and had to pause again.

[ihadabadday]

"Not really planned, but definitely wanted. I've been on bed rest since I told Sherlock. I've been in contact with that demon." He said as he rubbed his belly, "William is very excited. He wants a little brother." John chuckled.

"I would like a girl. And Sherlock just wants a healthy child."

"I will have to discuss with someone a method of birth control."

[seaweed_writes]

"The healer will have an herb that you can take for birth control. Or you can use the more.. common human method. " There was a grin on her face that shone through in her words.

"I... and I shudder to say this.. but I.. agree with Sherlock. I just want a healthy child. Although I have to admit that a boy and a girl would be nice." She sighed. "I do worry about you, but I can hear it in your voice. You are so happy."

[ihadabadday]

John just settled for rolling his eyes at his mother, even though she couldn't see it. "I will discuss it with him next time I go down." He saw the demon once a month.

He laughed. He couldn't help it. His mother agreeing with Sherlock. They didn't get along, but were always in agreement when it came to William. And now the newest member of the family.

"I am Mum. So very happy. Sherlock makes me happy. My son makes me happy."

[seaweed_writes]

"And this new child makes you happy." She finished the thought for him. "I get the feeling that you would be okay with having more children. But sadly, as your body is not made for it, every child is a danger- for you and for them.

"When will you see the healer next? I assume that he will be able to show you your child when visit next. I would guess that you are far enough along that you should have told me long ago." She chuckled. "I know you, John." She said with a smile in her voice.

[ihadabadday]

"I know. Sherlock gets so worried when I'm pregnant. I know it's because my body isn't made for this. But at the same time, it's rather sweet." He hummed, "He's got the kid gloves on with me."

"In a week." He answered, "And yes, I'm four months along. I meant to call you ages ago, but things have been so hectic. Sherlock wants to remodel. Again. I think we're finally getting that second bathroom."
