Sipping their drinks, they enjoyed a moment of calm before John spoke up again. "Do you two ever talk dirty in bed? Not just the normal stuff, but really filthy?"

Greg shook his head, "Not really the kind of thing either of us are in to, to be honest. Why is that one of your guys' go-to kinks?"

"For Sherlock it is," John said, taking a swig of his beverage. "It didn't take me long to figure it out either. I may not be the world's only consulting detective, or a Scotland Yard Detective Inspector but even I can figure out when something I have done causes that level of arousal."

Greg's face creased with puzzlement, "How do you accidentally figure out that he likes to talk dirty? Or is it that he likes to be talked to in that manner?"

Smirking, John answered, "Surprisingly enough, he likes it when I talk to HIM like that. For all the talking he does the rest of the time, you would probably assume he doesn't shut up in bed, but other than "Oh god!" "Yes" and "JOHN" it's mainly just incoherent moans and sighs and screams."

"Let me get this straight. You accidentally figured out that he gets aroused by you talking to him in a filthy manner? Okay, I'm probably going to regret this, but I want to hear this story."

John's head fell back against the booth as he contemplated how much to include in his narrative. "It was only about two weeks after we had first gone to bed together. In those two weeks, everything had been sweet, loving, romantic. He was in the best mood I had seen him in during our time at 221b and things were just going swimmingly. Then you called with a case and things got turned upside down for awhile.

"He was doing that thing he does where nothing but the case matters and he's basically an annoying dick all the time. I even told him that at one point. Finally, being nowhere near solving the case, even after three days of nonstop work, I knew we needed to relax. Up until then, sex had kept him soft and pliant for me so I attempted to seduce him in the normal way. Kissing his neck from behind while he worked on my lap top, lightly wrapping my arm around his torso, just brushing his nipples with the gentlest of touches. These were things that had worked for me in the last couple weeks but he just snapped at me that he had better things to do and I could just go have a wank in the loo if that was really what I needed.

"I was pissed. He wasn't getting anywhere and taking one hour off to decompress wasn't going to hurt him. So I leaned down, placing my mouth right next to his ear and practically growled, 'Sherlock Holmes, I'm going to have you right now. I'm going to fuck you so hard you won't be able to remember anything but my name. I'm going to put my cock in your arse and pound it until we both come, screaming so hard that Mrs. Hudson calls Lestrade to report an assault. I'm going to do all this, and when I'm done, you are going to beg me to do it again.'

"Where before there had been no response, now his skin was covered in gooseflesh, his cock was fully erect and when he turned to look at me his pupils were blown so large that there was none of that stunning colour left to be seen.

"Knowing what I had in mind would indeed reduce him to cries and screams of pleasure, I grabbed his hand and practically dragged him up the stairs to what used to be my bedroom. Pushing him down on the bed, I stalked over to him, crawling up his body, probably looking positively predatory.

"'You like it when I talk to you like that Sherlock? Are you a bit of a slut when it comes to me and my cock? I can see yours straining to get out of your pants. It wants me. It wants my mouth. It wants my hand. Your body is screaming out for me even when your brain is saying no. I'm going to make you come so hard your toes will curl and your throat will hurt from screaming. I'll make you call out my name again and again. I'll make you beg for my hand, my mouth, and my cock, and maybe, if you are good, I'll give them to you. Does that sound like a good plan Sherlock? Can you be good because I want nothing more than to pound my dick into your arse as hard and as long as possible?'

"He was trembling underneath me and it was by far the sexiest damn thing I had seen from him yet. It was obvious that my talking was turning him on in a way I had never seen before. I was loving this, the power I had over him. Irene Adler had spoken to him like this but he had rebuked her. When she told him that she would have him until he begged for mercy he responded that he had never begged in his life. But that day I had him on his literal and metaphorical knees begging me for some sort of release. But I'm getting ahead of myself.

"I slowly unbuttoned his shirt, my fingers skimming over the skin of his chest, perfectly smooth and pale, just like the rest of him. He's like a motherfucking male Snow White and I have him all to myself. As I pushed the shirt open, I bent and licked a broad swath up his sternum, before muttering into his neck, 'Your skin tastes like sex, love. And sin. I can hardly believe I'm allowed to do this. I'm going to bite and suck dark purple marks all over this perfect neck. Mark you. Claim you. Make sure every single person who you pass on the street knows that someone loves you, wants you, and gets to HAVE you.'

"I proceeded to do just that so that his torso, his neck, even his arms were covered in deep purple marks. Following each mark I pulled back to admire my work, giving him a look of utter lust. I wanted him to know that I'll always want him, always need him, and always HAVE him. I marked him over and over, muttering the entire time. "Sherlock, you are so fucking gorgeous. You are like walking sex. Do you know how often I have to stop myself from shooting people who look at you when we are walking together? You inspire lust in people wherever you go. After I'm done with you, no one will think twice because you will well and truly be mine. Love bites all over your skin, showing them that somebody fucks you. Somebody owns you. Because I do. You are mine Sherlock. And I'm yours. But tonight, I'll mark you, take you, have you. Again and again. Until you are begging for mercy. I'll do what the Woman was never able to do and I'll do it better."

His body was tight with tension, his cock so hard it ground in to my hip, even through the layers of my clothing. I pulled them off as soon as I could and went back to worshiping and ravaging that body. At each nipple I licked, kissed, nipped, and teased, my breath ghosting over them as I spoke 'Look how perky they are Sherlock. They want me. They want me to suck them, lick them, bite them. Do you like that? Do you like my teeth on those sensitive points? Does it make you want anything else? Because I'm just getting started. Even now I can see how turned on you are and I have not even touched that magnificent prick. And I won't for awhile. Not until you are begging for it. And then you will get everything. The release you feel be more intense than anything you have ever felt in your life and I'll be the one to give it to you. I'll milk every last drop from your body, leaving you quivering and pliant. Everyone will thank me for it, won't they? A happy, well fucked Sherlock is something that everyone at Scotland Yard likes. But no one likes it more than Sherlock. Who is so desperate for my cock that he's literally trembling.'

"The look in his eyes was one of pure and utter lust. I nearly gave up right then and there but I knew I needed to see this through, see just how much I could talk Sherlock into a frenzy. So far it was working but I wanted to try more. Eventually, I slid my legs up to straddle him, one knee on either side of his hips, my balls just barely brushing the underside of his cock. I grip myself and start stroking, my back arching slightly, as I continue my narration. 'Oh god, Sherlock, this feels so good. I'm so hard just thinking about you and what you do to me. If this was your hand, I would be thrusting in to that tight circle, wanting to come all over you, mark you yet again as mine. You want to touch, right? You want to feel my cock. You want it. Need it even. You are addicted and your addiction is my prick. You want it in your hand. In your mouth. In your arse. You are mine and I'll make sure you remember it.' I continued stroking myself, faster, while his hips came up to meet every movement of my hands. I had him basically pinned but occasionally he would get enough movement that his cock would bob up, brushing lightly against my knuckles and he would cry out in pleasure. He was sweating and panting, coming completely undone and I had barely touched him with anything besides my lips. It was the most arousing thing ever.

"Eventually I took pity on him. He wanted something. Anything. So I gave it to him. On my knees, I walked up so that my dick was in front of his mouth. 'Suck it, Sherlock. I know you want to. I have watched you look down at my prick and lick your lips. You want to taste the precum, don't you? You want my flavour in your mouth. You are so dirty. You want cock as much as you can get. So I'll be nice and give it to you. I'll put this dick so far down your throat that it's all you will taste for a week. Do you want me to come in your mouth? I can see you do. But I won't. Not tonight. I'm saving that for later. For now, though, I want you to put that sinful mouth to good use. All you have done is complain today so now you are going to make it up to me by sucking me until I tell you to stop.

"He did it too. The things that man can do with his mouth. Unf. God, I would marry him just to have blow jobs like that for the rest of my life. He sucked harder than he ever has and I could tell he was enjoying it, his face flushing and his eyes rolling back. 'All the precum, that is because of you. You make me hard and wet Sherlock. All I can think about is how good it will be to get my cock inside you.' Eventually, I pulled away and he made a bereft mewing noise which would have been adorable if I wasn't so damned aroused at that point.

"I still had not touched his cock, and I could tell he thought I was finally going to, but I skipped it, pausing briefly to lick the small moist spot on his stomach from all his leaking. I brought his legs up and positioned myself between them, licking at his balls before moving back to kiss his penineum and finally, back to his crease. I ran my tongue along the crease, before parting him slightly and licking at the tight ring of muscle. We had not done this before and I felt his whole body tense up. "Relax, love. Just relax and enjoy it.'

"Eventually he did and when tongue just wasn't enough, I prepped him with my fingers. 'You are so tight. You are going to feel so good around me. Is that what you want? Do you want my cock inside you? Filling you completely until you no longer know where you stop and I begin?' He just nodded, so I lubed myself, then got lined up, and pressed in.

"'Oh god Sherlock. You are so hot and wet and tight. And I'm the only one who has ever felt this, aren't I? You aren't a virgin but I'm the only one who has topped you.' He opened his mouth to say something, probably ask how I figured it out but I stopped him, 'I'll explain afterward.' I pulled almost all the way out so only my tip remained inside him before thrusting back in, causing him to arch off the bed and cry out.

"Things get a bit fuzzy after that. I know I kept talking. And by the time we were both coming, all he was saying was my name over and over again. 'John. John. John. John. John. JOHN!' It was a litany of sex. An affirmation of what I had told him. By the end of our night, the only world left on his lips was John. It was ridiculously sexy. And if you recall that one case involving the symphony, you will remember how grumpy he had been in the morning but how downright pleasant he was again that afternoon. You're welcome."

Greg just shook his head. The doctor managed to shock him again and again and this time was no exception.
