Jealousy (SherlockxReader)

It was a cold winter morning in 221B. Breakfast was sizzling and all was peaceful. Sherlock wore one of his maroon robes over his eggshell dress shirt; you were positioned at the stove cooking fresh eggs to serve with toast. The morning was fine, until you decided to switch the mood up a bit.
“Ollie’s is coming over tonight” You said, trying to sound careless.
“Oh, that won’t do” Sherlock quickly stated after, watching your face tense as you slowly slid the eggs off the pan, onto his plate.
“Why?” You spat, aggravated.
“Because Janine is coming over tonight too” The man casually added, placing his coffee onto the clustered table, while turning another page in the daily news. He glanced up at you, blinking innocently, keeping his poise. You only grunted for a quick response.
Sitting down, you served the plates and started eating your meal, watching Sherlock continuously drink his coffee. You two may have looked like a married couple, but for the past year after Sherlock's return, your relationship with him changed drastically...maybe even closer. Lets just say, you never know what you’ve got until it’s gone. Sure, this saying did contribute to you over the two years, but it affected Sherlock as well. He had to refrain from popping onto your doorstep and dramatically kiss you under the pale moonlight- but his return wasn’t all rainbows and butterflies. You found someone else to comfort you after a year and a half. It wasn’t necessarily your fault to hurt his minimal feeling’s, and you loved the detective with the burning passion of a thousand suns; its just that you just didn’t know he felt the same way, so now both Sherlock and you were seeing other people, yet still living together.
“That can’t work-” You rushed, intolerant of his date scheduling.
“It’ll be fine. I haven’t seen Oliver in a while anyways…” Sherlock said, his voice fading into bitterness.
“I wonder why” You coughed secretly, gaining a laughing scoff from your curly haired friend.
As the sun dimmed and temperature dropped, the sound of multiple footsteps followed up to the flat. “Yoohoo. (Y/N), He’s here” Ms.Hudson chimed, examining your brunette boyfriend, Oliver, from head to toe. Oliver drifted towards you, greeting you with a sweet kiss on the cheek. The nosy landlady stood by the door frame giggling, until Sherlock almost appeared out of thin air beside the other man. The detective reached to take Oliver’s hand to shake, but he grasped a bit too tightly, making it look like he “accidentally” brutally gripped the pressure points located on his hand. Oliver flinched his hand away to rub the pain. You should have see the mockery in Sherlock’s eyes, and how vulnerable your boyfriend looked.
“Hello Oliver” Sherlock’s deep voice said dangerously.
“Hi Mr. Holmes” Oliver greeted worryingly, oblivious to the hate protruding down at him. You were just standing on the sidelines, almost giggling at how your flatmate addressed your boyfriend. Your facial expression fell when you noticed how irrational your response was.
“Excuse me for one second” You spoke to Oliver, roughly dragging Sherlock away to speak with him privately, “What the hell are you doing?!” You harshly whispered, so your boyfriend wouldn’t hear you.
“Oh, just trying to strike terror into the heart of the enemy-” Sherlock sung innocently, but was then interrupted by another knock on the door frame.
“Hello?’’ The new guest made eye contact with the brunette stranger. “If this is a bad time-”
“No Janine, come right in” Sherlock mused, making a personality change. He marched towards Janine, and locked lips with face on face combat. It was so sudden, even Janine looked surprised.
“I’d like to keep this building PG please” You shouted with a hint of annoyance, trying everything to hide your internal fury. Sherlock swiftly turned towards you, extending his neck to look more intimidating and provoking, his face only inches away from your own.
“Why, are you jealous?” A childish fire burned in his eyes, until he noticed how inappropriate his actions were. Both Janine and Oliver were staring in disorientation, but you were even more enraged.
“I think I’m gonna go” Oliver uttered slowly.
“Oliver, wait-” you stampered, cut off by his suddenness.
“No-Bye” He shivered rushing out the door, making the scene even more abnormal. The room stood still, until the sound of a door closing broke the silence, indicating Oliver’s leave.
“Janine, I think you should leave too” Sherlock said, mildly embarrassed. She was still standing at the door frame, with the strange sense of escape. After you heard Janine clank down the stairs in her heels and out the door, you rushed to peer out the window. Oliver was still standing in the snow, but then Janine appeared beside him.
“Oh my god, what is he doing” You muttered in disappointment. They were walking and talking together all the way down the street, all the way out of eyesight.
“She’ll lighten up soon” Sherlock noted about Janine, which angered your thoughts. He could see your lips forced into a fine line, obviously in rage, “Don’t know about him-”.
“Shut up” This wasn’t a game to you and Sherlock could see your emotions overpower your mind. “I lost you, and now him?” Your voice broke into short sobs, showing how you tried your hardest to hold back everything. The dark haired man stared in realization of your pain, and felt like rubbish watching you cry helplessly. So he slowly, yet cautiously, stretched his arms out. You accepted his offer in an instant, clinging onto his chest while hiccuping and weeping. He awkwardly hugged you close and stiffly rubbed your back, not knowing what to do in sensitive situations like this.
“There, there” Sherlock breathed awkwardly, feeling your heartbeat near his chest. “(Y/N), It’s not your fault”
“Everything’s my fault-”
“No-It’s mine” Sherlock admitted loosely, which took you by surprise. You looked up to see his eyebrows arched and his eyes low, trying to avoid your pink brimmed orbs staring intensely at his face. His breath staggered and a warm air brushed against your lips. It took you three seconds to realize how close his face was.
“OH-I’m sorr-” you backpeattled too quickly, tripping over a shoe that was carelessly laying around. You were fortunately caught in Sherlock’s strong arms. He heaved you towards him, making you end up in an even tighter embrace. You slightly struggled to escape Sherlock’s arm cage, but he replied with an annoyed grunt.
“Stop” Sherlock grumbled. You soon gave up resisting, and laid your tired head against his slow rising chest. “You haven’t lost me” he sighed, “You’ll never lose me” You almost teared up again, but you still smiled into his dress shirt, trying to hold back an explosion of happiness and giggle fits.
“So, this is how you find out?” You questioned hopelessly, “Sherlock, I don’t know what to expect for an answer-well I do, but...I’ve loved you all this time-”
“Shush” He ordered, “I already know”
You paused, then started banging your head onto his chest, as if he were a wall, and you were trying to bash all your embarrassment away. Your cheeks flushed red, but you still held a smile as Sherlock lightly grasped your chin, tilting your head up so he could be looking straight into your eyes.
“Now this is how you find out” Sherlock whispered melodiously. His lips gently caressed your own for a smooth kiss, his hands resting on your back, while yours over his shoulders. You were surprised by how uncharacteristic his actions were, but you melted right into his arms. The rest of the night was warm, and peaceful, in 221B.
