Chapter Text
John practically dragged Sherlock away from the crime scene. Sherlock went along, scared. He had rarely seen John so upset, and had never seen that anger directed at him. John had Sherlock by the wrist, not squeezing so hard that it hurt, but holding tightly enough that it would be very hard to escape.
Away from the crime scene and around a corner into a dark alley.
“John?” Sherlock asked, wondering where the hell John was taking him.
John stopped walking, turned to look at Sherlock, and then pushed his back up against the wall, wordlessly closing the distance and kissing Sherlock.
He pulled away slightly, his forehead resting on Sherlock’s cheek, his eyes closed, afraid to look and see rejection on Sherlock’s face. “Okay?” he asked quietly.
“Oh, yes, John,” Sherlock told him breathlessly, putting his hands on either side of John’s face and tilting it up so he could kiss him again.
John moaned into the kiss, pressing his body into Sherlock’s. “I’ve wanted you for so long,” he whispered, reaching up into Sherlock’s coat and sliding his hands around his tiny waist.
“I’ve wanted you, too, John.” Sherlock’s voice was thick with emotion and John grinned against his lips.
John trailed his fingers lightly over the bandage on Sherlock’s side, which had only recently had the dirty knife removed from it. “We should get you to the hospital for a tetanus shot and a better bandage.” His hands made their way to the front of Sherlock’s trousers. “But first, can I—can I suck you?”
Sherlock froze. John was sure that he hadn’t been expecting that to be the first thing John asked to do, but John had been fantasizing about getting his mouth on Sherlock for years and he didn’t want to wait. After a moment, during which Sherlock stood there panting with John’s hand resting on the button of his trousers, Sherlock nodded enthusiastically.
“You are so sexy,” Sherlock murmured, caressing John’s face after John swiftly dropped to his knees and undid Sherlock’s trousers, freeing his erection from his pants.
John licked a strip up the underside of Sherlock’s penis and then slipped his mouth around the tip of it and sucked, making Sherlock moan and throw his head back into the wall. John hesitated and looked up at Sherlock at the sound of head hitting wall, but upon seeing Sherlock moaning with his eyes closed in pleasure, he just smiled and refocused his attention on Sherlock’s cock.
John took a deep breath and then slid Sherlock’s cock entirely into his mouth, scraping his teeth lightly along it as he pulled back. Sherlock let out a shout at that and gripped blindly at John’s hair.
Liking that reaction, John tried it again.
After a third time, John gave him a break and sucked hard, which made Sherlock pant harder and gasp out syllables, like he was trying to say something. He tapped John on the head, but John ignored him, knowing what he was trying to convey.
He scraped his teeth along Sherlock’s length again and it was over, Sherlock was coming, pulsing warmth into John’s mouth as John sucked him gently through it and swallowed.
John sat back on his heels, tucking Sherlock back into his pants and trousers, savoring the taste of Sherlock in his mouth. He expected that Sherlock would need a few moments to bask in the afterglow, but Sherlock hauled him up almost immediately, spinning them so John was against the wall and Sherlock was practically covering him as they kissed.
Sherlock was fumbling with John’s belt trying to get at the erection hidden within.
He had just managed to get his hands in Sherlock’s pants and was stroking him firmly, making John moan into Sherlock’s mouth, when Sally Donovan’s voice drifted into the alley where they had gone for some privacy.
“I think they went over this way, boss!” she called.
John pushed Sherlock away and had just buckled his belt again when Sally came into view at the end of the alley.
“Don’t you ever do anything so stupid ever again!” John said in mock anger, keeping his voice at a volume that Sally could just barely hear.
“I will do as I please, John,” Sherlock said and spun on his heal, striding out of the alley, ignoring Sally.
“Trouble in paradise?” Sally asked with a smile.
“Shut up, Sally,” John told her, struggling to keep the smile off of his face as he followed Sherlock.
