Sherlock Imagines

Army Sister (SherlockxReader)

"You need to chill, Sherl." You gently messaged his shoulders, trying to get him to calm down. You two had been secretly dating for nearly three months now. Neither of you wanted to know how John, Mycroft, or Lestrade would react. It was difficult, but you always managed to find just enough time for each other.
"How am I supposed to 'chill'? Mycroft knows. I know he knows." Sherlock was freaking out, because Mycroft had made a comment, resembling a joke, about Sherlock getting married to his 'girl'. Of course, Mycroft had no idea you two were dating, he was referring to Ms. Adler, who he had recently found out was still alive, and well at that. You circled around him, straddling him into his chair.
"Who cares? He didn't give you any gruff about it, it's fine! Who's he going to tell, anyways? Mr. Iceman, remember?" You both chuckled, and Sherlock just lightly shook his head.
"John. He'll tell John. Who will then rip me in half for 'ruining' his darling sister." He rested his head on your shoulder, and you rolled your eyes at his preposterous assumption.
"Sherlock, look at me." He reluctantly lifted his head, allowing you to be struck with those unnatural shade of azure, dulled, but somehow enhanced, with the silver undertones. You placed one hand on those high-angled cheek bones.
"That idea of John hating you, is ridiculous. You haven't ruined me, you haven't hurt me, you haven't changed me; I'm still me. What you have done, is love me, and made me love you. If anything, John should thank you. Alright?" Your voice was like suede as you spoke words truer than any he'd ever heard. He gave you one of those elusive smiles, one of the ones that he only seemed to get when solving a murder or while on a particularly exciting case. He pulled you closer, flicking his gaze to your lips for confirmation. You leaned closer in response, and your lips grazed each other's. He pushed his fully on to yours, and slowly started to let them dance in their excited bliss. It only took, but a moment for yours to become their partner. He let his hands rest on your waist, as yours snaked around his neck, gently swirling in his hair. These moments were few and far between, and you were sure to capture every moment of it in your mind. The kiss lasted for minutes, and only ceased after it was too late. John gently opened the door, a file in hand as he sauntered in.
"Hey, Sherlock, Leatrade wants to know if you'd be intereste-" He froze, staring in utter horrific shock to what he had just witnessed. You and Sherlock watched each other, waiting for someone to make a move, worry plastered on top of any and all other features.
"What the hell do you think you're doing?!" John's surprise quickly transformed into anger at his friend, and his younger sister. They turned their stare to John, as you both stood up, careful to make no sudden moves, like it would somehow send the beast charging.
"John, I can explain." Sherlock tried, not sounding very believable. He snuck a worried glance towards you, and you returned it. He swallowed a lump in his throat.
"Oh, really? You can explain why MY SISTER was sitting on YOUR LAP, while you were TYING TONGUES WITH HER?!" His voice couldn't seem to decide on a volume. Some points it was calm, others it was venomous, some were just plain furious.
"Actually, yes..." He trailed off, trying to decide how to tell John. You looked between the two nervously, fidgeting as John glared daggers into Sherlock.
"Oh, for heaven's sake! Me and Sherlock are dating. Have been for a while now," You picked Sherlock's hand up into yours, "See?" You took a deep breath, glad to finally get that off your chest. John's jaw dropped, and his eyes were the size of baseballs, as he stared between the two of you. You both nervously shifted, the tension building. Without warning, John clenched his jaw, returning to glaring at Sherlock.
"You bastard!" He hissed, "I'll kill you!" Seeing that this was going nowhere good, Sherlock began running, John following him, screaming threats.
"SHE'S MY SISTER! HOW DARE YOU!" You eventually got in between John and Sherlock, John staring in fury at the man behind you.
"John! Get ahold of yourself! I wasn't forced into a relationship with Sherlock! I'm happy, John! And if that means nothing to you, then fine. I'll go back to how things were before, only I'll be upset, and miserable! D'you want that?" John's eyes softened, and he looked to you. He began contemplating what this meant. His sister, and his best friend who was supposed to be vacant of any feeling, dating. In love. But... If he made her happy... John took a deep breath, and sighed, giving in.
"Alright, fine. But, Sherlock?" Sherlock was still in shock that John consented, but you were already hugging the older Watson. After a few whispered 'thank you's to John, you stood in front of Sherlock.
"You ever hurt my little sister, I know where you live." Sherlock looked at you, and took your hand in both of his.
"Oh, John!" He sighed sarcastically, "I'd never even dream of it!" He retorted, and you laughed, but John just realized how uncomfortable this was, so he decided to take this as his cue to leave.
"Um, sure, yeah. I think I'm going to go now..?" He pointed towards the door, but neither of you responded. He groaned, and exited the flat.
"See? Told you he'd hate me." Sherlock had to ruin the moment.
"Alright, fine. You were right. Now, where were we?" He smirked down at you, and pulled your lips to his once more.
