John was seated in a taxi on the way home to Baker Street snuggled into Sherlock's warm coat and nothing else. He was comfy and sanitized. Sherlock really did think of everything, though John was not surprised by that. Sherlock noticed everything at a crime scene; of course he would be meticulous about making sure there was nothing to connect him to one. John wanted Sherlock with him now, but he was finishing his clean up and would meet him back home. Memories of this evening's activities came to mind and he could feel his cock starting to harden. No, now is not the time for that. He was naked, wearing nothing but a coat that was too large for him; arousal could not lead anywhere good right now. But the coat smelled like Sherlock and being surrounded by the taller man's smell made not thinking about him impossible. He adjusted himself into a very uncomfortable position for the remainder of his trip to keep any sexual thoughts at bay. Upon entering the flat, he flopped onto the sofa, quite dramatically he must admit, in exhaustion. He's spending too much time with Sherlock; his habits seem to be rubbing off. But the sofa was welcoming and it too smelled like the genius. He wrapped himself in the coat and snuggled further into the sofa, falling asleep instantly.
Sherlock entered the flat quietly. He knew John was sleeping and wanted to wake him, but not quite yet. He thoroughly enjoyed their sexual encounter earlier and was ready to further explore his doctor's body, maybe by waking him with a tongue bath. He stopped when he noticed his coat on the sofa. There was a John shaped lump curled under it and the sight froze Sherlock in place. Seeing the smaller man in his seat covered by his coat caused a wave of possessiveness to crash through him. He wanted this man in a way he never wanted any other. He wanted to claim him, own him, and dominate him totally. This small unassuming man, a man that most people overlooked as being benign and placid, was his other half. His darkness matched Sherlock's own; the secrecy of their hidden lives no longer needed be a burden. They were laid bare each before the other and Sherlock expected to be afraid. He wasn't.
Sherlock walked over to the sofa and pulled his coat off of John slowly. He was still sleeping, and still naked. Blood rushed to his cock, tightening his already snug trousers. He carefully lifted John into his arms, being mindful not to jostle him too much. He paused briefly before deciding to carry him into his own bedroom. He laid him onto his duvet, watching as John curled into his pillow. He undressed and retrieved lube and a cock ring from his bedside table. Placing the lube under the pillow, he straddled his John, not resting his weight on him just yet. He slipped the cock ring onto John in preparation and then started at his left ear, licking from the root of the helix down to the lobe, nibbling slightly. John twitched. He then started licking down his throat, nibbling at his Adam's apple before moving across to his jugular and sucking. Sherlock heard the second John's breathing changed, knowing he was awake and aware of what Sherlock was doing to him. He shifted John's body so he was lying flat on his back, giving Sherlock more access. He ran his tongue along his clavicle, first to the right and then to the left. He circled the scar tissue which brought John to him. Sucking it and biting it, loving the smoothness of the scarred flesh, Sherlock could hear John's moans and smiled into his lover's skin. He ignored John's pleas for more, he wanted to savor this moment and worship him at his own pace. John's nipples were a pale pink before Sherlock started on them but were a deep rose colour by the time he moved down his abdomen. John's muscles rippled with soft laughter as Sherlock tickled him with tongue and teeth. It wasn't until he started tongue fucking his navel that Sherlock actually had to hold him down. John was writhing uncontrollably, begging Sherlock to remove the cock ring and fuck him, but Sherlock wasn't ready for that yet. He needed to mark every bit of flesh as his property. He knew there had been others to touch this body before him, but none had pleasured John this thoroughly, none had known him this intimately, and none would follow. Sherlock's marks were a declaration of dominion, to John and anyone else daring to look closely enough.
John's inner thighs were incredibly sensitive, Sherlock could hear the tears in John's voice as he continued to plead with Sherlock, but he never was a merciful man, and he was not going to change now. The backs of his knees proved to be another ticklish spot, and Sherlock was almost given a black eye for his trouble. His lower back was another, and Sherlock's cheek would definitely bruise, but it was worth it to hear the beautiful keening coming from his frantic doctor. By the time he had licked back up to the back of John's neck, Sherlock wondered if John would have a voice tomorrow. He smirked imagining how sexy a raspy John would sound. John was covered in sweat, dripping pre-cum and crazed with lust. Sherlock reached under the pillow and finally retrieved the lube. He parted John's plump ass cheeks and looked at his anus, watching it clench, anticipating the feel of it surrounding his cock, milking him. He lowered himself and licked along his opening, John could barely make a sound by this point, too far gone to the fog of lust to verbalize properly. Sherlock started fucking John with his tongue, rimming him enthusiastically. He sucked and nibbled along his ring, thrusting his tongue, starting the process of opening him up. He reached for the lube and coated his fingers. His tongue loosened him up enough that he could start with two fingers, working them into John and opening him further. By the time his third finger was comfortably inside, Sherlock could wait no longer. He needed to be inside of his John, he needed to cum deep inside his lover. He coated himself with lube and placed his cock at John's entrance. Pulling John back against his chest, he whispered into his ear, "I'm going to fuck you now John. I'm going to fuck you hard and fast. When I'm ready to cum I'm going to remove the cock ring and you're going to cum with me. Do not touch yourself, you will cum from my cock in your ass only. The pleasure I provide will be the only thing to bring you release. Do you understand me John?" John moaned desperately, his breath catching on a small sob. "That wasn't an answer John." Sherlock's words were slightly threatening, demanding an answer. John licked his lips and very quietly, whispered, "Yes." Sherlock's smile was almost malicious. He thrust into John deeply, filling him completely and immediately starting pounding into him. John's screams were glorious. Sherlock did as he promised and fucked John hard hitting his prostate over and over again. He used all of his strength to pound into him as hard as possible. He wanted John to feel him for days. He knew he was nearing his end so he reached around to John's cock and released the ring. "Cum with me John, cum now." His command was followed beautifully. John came screaming his name as Sherlock screamed John's. They collapsed onto the bed, Sherlock still encased by John's body, reluctant to remove himself. Sherlock tightened his hold on John's waist, pulling his head around to meet his eyes.
"Mine." He growled, letting John see the seriousness of his declaration clearly on his face.
John didn't react. He merely studied Sherlock closely, once he saw what he was looking for, his eyes softened. "Yours."
Sherlock finally pulled out of John and allowed him to go under his covers. He tucked John into his side and draped his arm over his body, clutching the plump ass that now belonged to him. He relished in the smells surrounding him. Their sweat and sex combined was intoxicating and comforting. Sherlock allowed the warmth of the man beside him to lull him into sleep.
