Sherlock went very very slow at first. "Look at you, my little one. You are taking my entire hand like a champ. I am so, so proud of you. Are you okay, John? You have to tell Daddy that you are OK before I move faster or deeper."

"Do you want me to continue, my love? Use your big words."

John swallowed and took a breath. "I'm okay Daddy..." he told the vampire, "Please don't stop."

The pressure was intense, but it only made him want more. More of his mate, more of the stretch. Maybe the dragon dildo. Forced to ride it while he sucked off Daddy.

"Good boy." Sherlock beamed. The shower was still beating down on them, thankfully it was still hot- thank goodness for the water heater. He shifted so he was a bit more under the water flow, which also pressed himself against John, so John could feel Sherlock's hard cock against his back.

He started to move his fist in and out of John's arse, moving it deeper and faster now. each pushed brushed against his prostate and stretched him a bit more. "Good boy.. Such a good boy. You are taking it so well, nice and tight around my hand. You aren't going to come yet, are you? I know you won't because you are my good little slutty boy who wants his hole stretched, don't you?"

John gasped and moaned with each movement of Daddy's fist inside him. Oh yes. Yes. He shuddered and pushed his hips back. Nothing more than a good slut for Daddy.

"No Daddy. I won't come. Not until you tell me. I want to be a good boy for you. I want you to get everything that you want from me."

"Oh, you are my good boy. I promise I want to make this good for you." It was such a strange paradox, that John could be in his massive Demon form, and still fall under and trust Sherlock enough to take care of him. It was a huge responsibility, and one that Sherlock took quite seriously.

Sherlock worked him open a bit more, using his wrist, and then the very first part of his arm inside of John, stretching him wider and wider.

"Look at my wonderful, wonderful boy. You are all stretched out around me, big and gaping and open, aren't you? I think it's time you got your reward. Do you want Daddy's cock in you now? I know I won't open you up like my fist will, but I can give you your sticky reward. Is that what my good, sweet, wonderful boy wants now?"

John couldn't focus for a moment. He felt like he was floating, the pleasure so intense. It felt like it was going to overwhelm him. He sobbed and shifted a bit.

"Daddy please. May I please have your cock and my reward? Please?"

He pressed his forehead against the tile, trying to calm himself. It was so intense and he just... He wanted. He needed.

"Of course, my wonderful boy. You are so good for me, aren't you? You deserve everything that I can give you, and more."

Sherlock knew that he had to be careful, so he pulled his fist out very, very slowly, adding a bit more shampoo as it went to it would slide out with the least amount of resistance. When it finally released with an actual, audible pop, a steady stream of shampoo and water came with his.

He had to wait for a moment.. just to marvel at John. God, he had never in the almost year and a half that they'd been together, never seen him this open and stretched and fuck it was the hottest thing that he'd ever seen in his life.

"Mmmmmm." He couldn't resist leaning down and licking at John. He was so open that his tongue went right in, but it was a bitter taste of shampoo on his tongue, so he sadly abandoned that idea.

Instead, he took his cock in one hand and held John's hips with the other. No need to hold him open, he was so wide already. He did use a litlte more shampoo, just in case.

"Are you ready, my wonderful, lovely, open boy?" He asked, as he started to push in with a grunt. Between the shampoo and the gaping from his fist, Sherlock slid in with no resistance at all, right up to the hilt.

"Ahhh.. you feel so loose around me, not like your usual tight and hot hole. I wonder why. " He giggled while he started to thrust.

John yelped when that fist was pulled out. He groaned and closed his eyes. Ohfuckyes. He could feel how open he was and ohgod. He wanted that cock. Any cock. He wanted his gaping hole filled up.

"Daddy please. Please fuck me. Put anything you want in my hole..."

He groaned when he felt that cock slide in. Ohyes. He shuddered and pushed back. He tried to clench around the cock inside him, but no luck.

He shifted, whimpering, holding the base of his own hard cock. "I could take the dragon cock with ease.."

Sherlock was rutting softly at first, loving the feeling of how loose John was around him. It was a strange sensation. There was still the slightest bit of friction, but he was very loose and would stay that way through this nice and easy fucking.

"Yes, you could." Sherlock said, with a rather brutally hard thrust, then he went back to his slower, more rhythmic pace. "But I was rather hoping that I would be able to fuck you and put my seed in your hole. Who knows. maybe you can be a good boy for Daddy and my seed will catch." He knew it was a very very long shot, especially just 3 months after having a child, but there was always a chance.

John nodded. "Please give me your seed Daddy. Please..." he begged.

The blonde pressed his forehead against the cool tile, whimpering. He wanted his Daddy's seed. He wanted to be bred for the vampire. Grow big with Daddy's child.

"Of course, my good boy. You have been such a wonderful boy that you deserve your reward." Sherlock immediately went from a a soft, slow rhythm to a hard buggering fuck, enough to keep pressing John against the tiles with each thrust inside of him.

"Mmm.. gonna give you all of Daddy's seed." He growled while thrusting harder and harder. He wouldn't last long, he could already feel his body tensing, feel the pressure growing.

"Nnng... take it all.. take me!" He was almost animalistic, even he had no idea where it was from, but with one loud growl, a hard thrust using all of his body weight, he pushed hard into John and cried out as he came deep inside his lover, ropes of his salty essence spilling deep inside of him.

He cried out when he felt Daddy fill and fill him. The blonde shuddered, but didn't come. He didn't want to disobey Daddy. No. He whined and shifted a bit, pushing back.

This was... It was perfect and amazing. He moaned weakly, eyes closing. He was so needy. He would do whatever Daddy wanted. Needed.

Sherlock continued to thrust until there was no more left inside of him. He pulled out, a steady stream of come came with it, because he was still so open, it just slid right back out.

Well, so much for getting him pregnant this time. Sherlock thought with a little smile. There would be others. He wasn't terribly upset about it. And besides, it was pretty sexy seeing John leak his seed out of his arse.

"Such a good boy." He crooned, turning John around in the spray to kiss him deeply. "Now. do you want your second reward?" He asked. "I know you must want to come really badly, don't you?
He reached down and gave John's cock a little stroke.

"You know what you need to do, my sweet Demon boy. " God, just looking at that giant Demon cock could almost make him hard again.

Almost. He was still pretty spent after that fisting and fucking session.

John let himself be maneuvered and he stared at Daddy. His head was spinning and he... He swallowed and nodded.

"I'll give you whatever you want Daddy." He said.

The demon would do whatever his Daddy wanted. He wanted to prove to him what a good boy he could be.

Sherlock turned so that he was facing the shower tile now. He spread his legs and looked over his shoulder.

"Be a good boy and take what you know you want." He reached back and used his hands to open his cheeks, giving John a good look at the puckered entrance, with a rivulet of water running down, past it, and down his thigh.

"Give me all of you."

His primitive brain took over and John stepped over to his Daddy. He ran his clawed hands over his back and arse. John licked his lips and took ahold of his cock.

He moved the tip against that puckered hole, whimpering. He wanted to bury himself in that warmth. And with a shove of his hips. He did.

Sherlock shivered at those claws, they made his skin break out into goosebumps.

"Mmm.. yes.. Good boy." He crooned, encouraging John. "Take me, you know that you want your reward."

"Nnnng!" No matter how many times John did it, or how much lube or water or stretching there was, it was always a shock to feel that gigantic Demon cock push into him. He grunted in a mix of pain and pleasure and leaned his arm on the shower tile and laid his head on his arm. There had been no lube, no warning, and suddenly he was speared open.

John couldn't think. Or focus. Once he was in that tight heat, he began to pound away, taking his pleasure.

He was told he could. Take what was needed. Over and over.

He groaned and buried his face against Daddy's neck as he thrust. His massive cock working in and out of the vampire. He wanted... He needed...

"Nnnnfff...." Sherlock was stretched wide and fucked hard, and he loved it. The pain and pleasure mixed into a heady cocktail of endorphins. He knew that John would pound into him hard, so he expected it, but even with that, it was still intense.

He shut his eyes and leaned against the wall to brace himself. And it still wasn't enough, but he didn't mind.

"Mmm.. g-good... b-b-oy.." He grunted out while John thrust hard. "t-t-ake.. what's... yours.."

John couldn't quite hear him. He was too far gone in the pleasure. It was tight and hot and... He bit on Daddy's neck as he thrust. In and out. Over and over.

The demon grunted as he reached his climax, his seed filling Daddy.

"Mmmmmmffff.. " He hissed when John bit down on his neck while he thrust harder still, moving him forward against the tiled wall with each thrust.

When John finally came, he could feel that gigantic Demon cock pulse inside of him, and waves of hot seed filling him and dripping down his legs and mixing with the shower water, eventually circling round the drain and going down.

Sherlock was hard again, but he wasn't really worried about himself. He let John drain himself inside of him, whispering to him how he was a good boy and he was so proud of him and he felt so full and he loved having his boy inside of him and coming inside of him and using him.

John dropped to his knees in front of his Daddy and looked up at him. "Please. Use me however you want. I'm yours."

He shifted a bit, feeling so open. It just made him want to be filled and filled. Over and over. And as long as it made Sherlock happy, he was fine with it.

It was always disappointing when John pulled out of him, there was the feeling of emptiness, and of course the continual drip of semen down his leg.

He smiled down at John, ruffling his hand through his lover's hair. "Such a good, good boy." He cooed. "Open your mouth, love.

Sherlock took his cock in his hand and started to stroke himself right by John's face. It only took a few quick strokes before he was coming all over John's face and in his mouth and his hair. "Mmmmmfff.." He sighed and had to lean on the wall when he was done. He'd come twice pretty quickly and was drained, quite literally.

"Clean yourself up love, we are almost out of hot water." He said with a soft, tired smile.

John nodded and then rose to his feet. He ducked under the spray to wash the semen off his face and then quickly washed himself down.

He gave Sherlock a kiss and got out of the shower. He then began to dry off, using the time to slowly come back into himself.

Sherlock let John clean himself off, then Sherlock cleaned himself, working around his arse and legs extra well, he was still leaking some of that Demon come out of his hole.

When he was done, he toweled himself off, and wrapped his arms around John, holding him while he came up from his headspace and back to the world while Sherlock told him that he loved him and that he did a good job and that he was safe and it was time to come home again.
