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.

"Please." He begged softly, "Please..."

He wanted the connection with his mate, to feel wrapped up in him and and...

John turned to look at him. "Sherlock..."

[seaweed_writes]

"Okay." The word was soft, almost whispered.

Gently, Sherlock guided John to sit on the bed with some pillows behind him so he could lean back and be comfortable. Button by button, Sherlock undid John's shirt, pulling it out of his trousers and off his shoulders onto the bed.

Sherlock climbed into bed, a bit awkwardly, it was hard to figure out what position would be best to do this, but he finally did. He sat for a moment, admiring the way that John's breasts had grown. They weren't huge at all, maybe A or B cups, but it was enough to feed their child.

And him.

He settled in, kissing John's breast, licking at it, at the nipple and around the areola, before finally putting his lips around the left nipple, and starting to suckle, lightly at first.

[ihadabadday]

Oh.

This had not been what he meant at all. He had meant blood. But this... He let Sherlock maneuver him and lay him down. Let his mate undress him.

John stared down at that curly head, in awe. He was amazed. Amazed that Sherlock would do this. He had only been half serious when he spoke during their last intense session before he gave birth.

But seeing it... He gasped softly when he felt those lips press against his breast, that tongue against his nipple. John groaned when those lips closed around his nipple and sucked.

[seaweed_writes]

It took a few suckles for the milk to start flowing. When it did, Sherlock's eyes went wide when he first tasted it. It was almost like cow's milk, but a bit more mild, and a bit sweeter, and a bit thinner than cow's milk. He really had no idea what he was expecting, but that was not it.

And yet, it was quite nice. It was warm because of course it is John's body temperature, and John's temperature (being a demon) was higher than his. One would think that warm milk would be bad, but he found it quite comforting, and he suckled eagerly, snuggling as much in John's lap as he could.

[ihadabadday]

John let out a breath, running a hand through Sherlock's hair. He swallowed as he relaxed. "Sherlock..." he whispered, almost in awe. His mate was amazing. Wonderful.

He closed his eyes. This was probably taboo somewhere. But he didn't care. Their relationship was no one's business.

They had promised... Them against the world.

[seaweed_writes]

Sherlock could feel himself falling, regressing. He knew he shouldn't his brain was trying to resist, but he was in John's arms, and John was whispering to him and running his hand through his hair and he was curled up as best he could in John's lap, drinking from him.

It was all too much.. "Mommy..." He whispered, the last little bit of his brain that was in the present hoping that John wouldn't mind.

[ihadabadday]

John's breath caught and he couldn't prevent the tightening of his trousers. Christ. How was that so erotic?

"My good boy." He whispered, "Drinking all of Mummy's milk." John knew Sherlock loved the praise. "You need to drink it all so you grow big and strong."

[seaweed_writes]

"Mmmm.. Mummy...." He said his voice soft and child like. He wiggled in John's lap, trying to get at close as he could to Mummy, gently laying his hands on John's bare chest. He was so happy with himself, Mummy called him a good boy. He wanted to be big and strong and make his Mummy proud.

[ihadabadday]

John continued stroking his hair and praising him as he drank. He didn't stop his mate until no more milk came.

"Good boy. You drank all of Mummy's milk." He cooed. John ran his other hand over Sherlock's back.

"I'm so proud of you."

[seaweed_writes]

Sherlock made a little groan of disappointment when the milk ran dry. He suckled for a couple of moments more, then he pulled off with a little pop. There was milk dribbling from the sides of his mouth, and he licked his lips. He was sated and a bit milk drunk, deep under and happy.

He smiled at the praise, but he was too far under, and he couldn't speak, so he just made a soft noise of contentment. Mummy was proud of him, and that was all that matters. He beamed with happiness.

[ihadabadday]

John kissed his head and maneuvered them so Sherlock was curled up on their bed. "Take a nap my sweet boy. Mummy will check on you in a little bit."

He slipped off the bed and pulled the covers over Sherlock's prone form.

That had been unexpected. But they trusted each other with all that they were.

[seaweed_writes]

"Okay, Mummy... Love you.." His voice was low and sleepy. Sherlock snuggled up into the sheets and was asleep in just a few minutes.

[ihadabadday]

John dressed and then checked on William, who was fast asleep. He turned on the baby monitor and went into the kitchen and living room. He would make some tea and then check his emails.

[seaweed_writes]

Wakefulness came slowly to Sherlock. For a few moments, he wasn't sure where he was or what he was doing.

Then he remembered, he had drank from John, and it had regressed him. He hadn't intended it to happen, but it had.

And it had been wonderful.

He got up and stretched, then padded over to William. He was awake but not crying yet.

"Come on, love. Let's get you up and fed." He held William close and padded down the hallway. He heard John in the kitchen. He walked in and kissed his mate softly on the cheek. "Thank you, love. That was.. amazing. I didn't mean to, though. I am sorry that happened so quickly."

[ihadabadday]

John turned when he heard movement. God what a gorgeous sight, his mate holding their son. It made warmth bloom in his heart. How had he gotten so lucky?

He returned the kiss. "It's alright. Though I had meant blood. But that was a wonderful experience. Thank you for trusting me with it."

He took William and kissed his forehead. He was sure the babe was hungry. He pulled his shirt up and brought their son to the breast Sherlock hadn't drunk from.

[seaweed_writes]

Sherlock frowned. What if he did that again, and William actually didn't have enough milk to drink? He shook his head. He should have thought about this more. He just did it without thinking about their son.

"I'm sorry." He said again. "I know you will need to drink my blood soon, John, so that William and get those proteins that he needs from a Vampire's blood. Perhaps when he goes back to sleep."

He touched William's head as he nursed. "Thank you for letting me do it. I don't think I should do it again, but I very much enjoyed it. I think we were both.. getting a bit excited from it." He said with a little blush.

[ihadabadday]

"Sherlock... My body will replenish the milk that you drink. If you want to do it again, we will do it again." He said, "The only reason I put William on this breast was because it's heavier than the other one."

He smiled warmly at the vampire. He wanted to make him happy.

[seaweed_writes]

He knew, of course, that his body would replenish the milk, though he had no idea how long it would take, and he hated to think that his son would have to wait because he was greedy.

"If... if.. it replenishes fast enough.. I.." Sherlock was blushing deeply. "I would.. like.. to do it again.." He knew that it had aroused both of them, he could feel John's arousal against his leg as he'd snuggled in John's lap. Maybe they could do something about that, but they would have to be careful, because William's sleeping schedule was.. well, it wasn't really a schedule at all. It was random, it seemed.

[ihadabadday]

"We'll see. It seems to replenish fast enough when we were with the healer." He said.

John looked at his mate. "Will you order athai?" He asked hopefully.

[seaweed_writes]

"Okay." Sherlock smiled. He kissed John, then went to the living room to order Thai. By now, he knew what John liked, and he ordered for both of them. When he was done, he came back in. "Got your Pad Thai and Tom Yum Gai."He said, taking a seat and watching William continue to nurse. "Should be here in about 45 minutes. "

[ihadabadday]

John pulled his shirt down when William finished nursing and put the babe against his shoulder.

"Thank you." He moved over to the couch and sat down.

John yawned and closed his eyes for a moment.

[seaweed_writes]

Sherlock took William, who fussed a little bit. He gently burped him, then took him to the couch to lay him down and change him.

"Go to bed, John. William has been keeping us up. I'll wake you when the food gets here." His voice brooked no argument. "Love, you need to rest. We'll be OK." William was already fussing less as Sherlock changed his diaper. No poop, he got lucky this time. "You don't need to sleep on the couch, the bed is much more comfortable."

[ihadabadday]

Three months in, John was still ecstatic to have William. But he had made the decision to go back to work. Sherlock was home during the day and they had trusted Mrs. Hudson to watch William when they were both out.

He was coming in the door one evening, rubbing his neck. He pulled off his jacket and hung it up before going into the kitchen. A note from Sherlock. It seemed they had gone to visit Mycroft. He smiled and went to take a shower. Get the day off him.

[seaweed_writes]

It had been a tough but amazing three months. It seemed to just fly by. William was growing, but his sleep schedule was still crazy. They were still not getting much sleep, and they were both exhausted all the time. They had kissed and made out a bit, but no sex yet, which was fine for Sherlock. He loved John and he would wait as long as John needed.

He was very surprised when John decided right after William turned three months old to go back to work. But of course he supported John in whatever he did. It was exhausting work to be alone with a 3 month old all day, and he got little done in the way of cold cases, but he wouldn't trade William for anything in the world.

One day, Mycroft summoned him. He tried to tell Mycroft that he couldn't go, but he insisted, saying that it was about William, so reluctantly left his son with Mrs. Hudson and went to meet Mycroft.

It was late when he get back. Mrs. Hudson still had William, so he figured that John was not home. He took his son, thanked the woman, and then went upstairs. He could hear the shower running.

"Let's go say hi to Daddy." He said to William, who just made a noise and flapped his arms.

Sherlock opened the door, and was hit with a wall of steam. He quickly closed the door again to keep the heat in, then he opened the curtain and stuck William's head thru.

"Daaaaaddddyyyyy..." Sherlock said, trying to make it seem like William said it. Of course he was way too young to speak yet, but still.

[ihadabadday]

John was surprised when his shower was interpreted by his son being put through the shower curtain. He laughed and then pulled it back a bit further. He smiled at his mate.

"Welcome home you. I'd kiss you, but I'm all wet."

John was still gloriously tanned, perhaps a side effect of being a demon. He had a slight softness to his middle still, and his breasts were full of milk, but one would say, almost perky.
