Sherlock X Reader: Deducing You (One-Shot!)

221 Baker Street




You were standing in Sherlock’s apartment making some tea for him and you’re Brother John. You hummed quietly when you turned around and saw Sherlock leaning against the door frame looking at you up and down. You turned back around and just continued making tea.

John was standing in the living room reading the newspaper, “Sherlock? Did you read about this new case in the paper?” John asked looking up at Sherlock realizing he was staring at you.

Sherlock wasn’t paying any attention to him.

“Oi! Stop staring at my little sister!” John snapped and put the newspaper down on the table walking over to Sherlock.

“I’m not staring at her, I’m simply deducing her” Sherlock replied.

“No, you’re staring at her” John let a slight growl out.

Sherlock rolled his eyes and sat down at the dining table, he was looking through his microscope, he looked down at his stack of notes and nodded.

You turned around and looked at Sherlock setting down a cup of tea in front of him.

“Thank you…” Sherlock muttered softly.

John walked back into the living room but stopped and turned looking at Sherlock, “Did you just thank her? You never thank anyone…” John looked at Sherlock shocked.

“Nope” Sherlock replied and continued skimming his notes.

“You’re welcome Sherlock” You smiled softly and sat down and took a sip of your tea, “Sherlock take a break and drink your tea” You looked at him.

Sherlock looked up at you with his bright bluish with a mixture of green and grey; he slowly pushed his microscope to the side and picked up his mug of tea taking a sip of it.

“Did you just tell Sherlock what to do?” John looked at you, “And you listened to her?” He then looked at Sherlock and laughed.

“I have something to tell you (Y/N)” Sherlock said setting down his mug in front of him.

“Have you heard from mom at all?” John interrupted Sherlock and looked at you curiously.

“No I haven’t heard from more or dad, like I really want to hear mom talk about dad’s bowel problems and how she bickers about how we never come and visit her” You looked at John.

“Never mind than… Carry on” John muttered with a wave of a hand.

“Sorry what were you saying Sherlock” You looked at him.

Sherlock was about to speak when John interrupted him once more.

“How’s work going?” John asked looking at you.

“I got fired John, I told you that already, that’s why I’m staying with you” You let out a slight giggle, “I’m looking for another job okay… It’s hard to find work in London” You sighed.

“Why did you get fired again?” John asked.

“I punched my boss in the face because he was being a prick” You explained.

“Oh…” John muttered softly and looked at Sherlock than looked back at you.

“John may I speak now?” Sherlock asked.

“Yeah, go ahead…” John replied.

Sherlock waited a few moments hoping John wouldn’t interrupt him again; Sherlock gave you a soft smile looking deeply into your (E/C) eyes.

“Why are you looking at me like that?” You asked looking at Sherlock; your cheeks went a slight shade of pink.

“I can tell by the tinge of pink on your cheeks you are flattered by me looking at you” Sherlock smirked.

“Oh I am much more than flattered, no one ever looks at me like that…” You muttered softly.

“(Y/N)?” John asked.

“John! I love you! But shut the bloody hell up… Me and Sherlock are trying to have a conversation” You said sternly.

“Woah… Okay…” John muttered softly and slowly backed away and just paced around the living room.

“Sorry Sherlock…” You muttered softly.

Sherlock just kept staring at you; he smiled softly and watched your cheeks grow a darker pink.

“Are you observing me?” You asked crossing your arms.

“I’m admiring your beauty” Sherlock replied.

You gasped looking at Sherlock shocked, you looked down and smiled giggling cutely, “I’m sure you could find much a prettier women, there’s plenty in London” You muttered softly.

“You seem shocked, you shouldn’t be… And I don’t want another women, I want you” Sherlock said sternly.

“Sherlock… What are you saying?” You asked.

“I love you” Sherlock replied.

John turned around and looked at Sherlock, his mouth dropped, he turned around and just had the look on his face of what just happened.

You smiled at Sherlock, “I love you too” You replied.

Sherlock stood and walked over to you, he ruffled his curly black hair before leaning down and pressing his lips against yours.

John looked even more shocked now, “Oh my god…” He whispered to himself.

You closed your eyes slowly kissing back.

“That’s my sister Sherlock!” John shouted.

Sherlock slowly pulled away looking deeply into your eyes, he grinned and walked back over to his seat and sat back down.

“By the state of your eyes being glazed over with excitement as well as your face being red, you also are clenching your legs tightly and shaking so that means you are sexually aroused” Sherlock said.

“Okay we do not need to talk about my sister being sexually aroused, Sherlock you don’t love anyone and my sister of all people, you wouldn’t like her” John walked into the kitchen.

“Oi! Stay out of this John!” You snapped.

“I’m you’re big brother and I promised mum and dad I’d protect you!” John said sternly looking over at you.

“I’m a grown woman!” You shouted.

Sherlock just sat there watching you and John fight, “I agree with my girlfriend” Sherlock grinned.

“I’m your girlfriend?” You looked at Sherlock and smiled happily.

“She’s your girlfriend?” John looked at Sherlock.

“Would you like to go out for dinner with me?” Sherlock asked looking at you curiously.

“I can’t believe this is happening…” John mumbled looking at you shocked, “You don’t want to go out with Sherlock, he’s a prat” John said.

“He’s not a prat John” You said sternly, “Come on Sherlock” You got up and kissed Sherlock’s cheek, you handed Sherlock his coat. Sherlock took your coat off the chair and helped you put it on, you blushed and smiled putting Sherlock’s scarf on him.

John sat down in his chair, “I swear to god Sherlock if you snog my sister your dead” John threatened. “That’s my decision John Hamish Watson, not yours!” You called and walked out of Sherlock’s flat with him.

“Well… I guess I’ll make myself some tea than…” John muttered softly and got up walking into the kitchen, John quickly picked up his phone and texted you. I’m glad you’ve found someone little sis, have fun, love your big brother John.
