That Time Of The Month - Sherlock xReader

"That time of the month, is it?" Sherlock didn't even look up from his mind palace position on his chair.

You looked at him baffled. Yes, you had gotten your period this morning, but you didn't think it was noticeable. You ran through everything you had done, this morning, in your mind. Bathroom, like usual, kitchen for tea, like usual. Everything you did this morning was normal. 

"I swear to the gods, if you are counting the days..."

"No, (y/n), I don't have to count the days." Sherlock cut you off, obviously offended. "I just know."

You plopped down on John's chair, now sitting across from him. You took a sip of your tea, before leaning forward, "Well, tell me, Curly, how did you 'just know'?" You mocked his words.

Sherlock stood, his eyes studying you, as he walked around John's chair. He placed both hands on the back of the chair and leaned over you, "Well, for starters, you're in sweatpants today. Now, any normal person wouldn't see it as anything, but you never wear sweatpants unless you are bloated. Seeing as you didn't have a large intake of sodium for the past few days, and your bowel movements have been regular, there is only one reason for you to be bloated. You're menstruating. Secondly, you took longer in the bathroom. I could assume that either, a) Something you ate upset your stomach, or b) you started your period." He paused for a moment, looking down at you. "Honestly, (y/n), it's not that hard to tell. Plus you're rigid, and your phone made an alerting sound two days ago." You looked at him questionably, so what if  your phone made an alerting sound, what does that have to do with anything? "That sound only happens on the weeks when you begin menstruation, so, I figure that you have an app that alerts you on that week." He smiled at you, before walking over to the kettle. 

After he filled the kettle and flipped it on, he began rummaging through the kitchen. You were still in too much shock to speak, you could never get over him and his deductions.  As you were completely silent, Sherlock walked back over to you, a hot water bottle in his hand, and some pain killers in the other. He handed you the hot water bottle, which he had wrapped in a towel in case it spilled, and put the pain killers on the table beside you. 

You were shocked, what was this sentiment he was showing, almost as if he cared. You shook the thought from your head and looked up into his icy blue eyes, "Thank you?" It came out more as a question than a statement.

Sherlock flopped back onto his chair, "It's nothing." He smirked before going back into his mind palace. 

The two of you remained silent for the next hour, you had your headphones in while watching a movie on your phone. After a bit, you looked up, watching Sherlock, and completely disregarding your movie. You couldn't help but wonder what had made him act so...nicely, it definitely not like him. Not that he was mean, but he was just never nice. 

"Your staring is distracting." Sherlock grumbled, before turning to look at you. "You didn't think I wouldn't notice, did you?" He smirked.

You laughed, pulling the hot water bottle closer, though it was beginning to get cold, "Of course I knew you would notice, I'm not stupid." Sherlock opened his mouth, as if to object. "Shut up." You smirked. "I just like watching you think, it's interesting."

A look of slight shock flowed through Sherlock's face, causing you to laugh. "How is it in your little head? So boring that you find entertainment in watching someone else think. I guess it's because you don't do much of it yourself." Sherlock gawked.

Damn, that was harsh, even for him. You looked at him, rolling your eyes, "I find it interesting that someone as stupid as you, can think for so long. Honestly, Sherlock, what makes you think you're so smart?" You bite back, your tone even harsher than his.

Sherlock glared at you before a smirk landed on the corner of his mouth, "Well, if I'm so stupid, how did I figure out that you were menstruating?" Sherlock laughed lightly.

You glared at him, rolling your eyes, "Counting the days, deducing me, I don't give a rats ass. You're not stupid in that regard, but you are absolutely clueless when it comes to humans."

Sherlock cocked an eyebrow at you, but before he could speak, you continued, "Like, for instance, you can't figure out Lestrade's first name, and you can't even tell when your roommate has a crush on you." You smirk, you just let out your biggest secret, and here you were, waiting for a response.

 You had developed a crush on him, probably about three months ago, just before you had moved in. The thought of living with your crush, especially with a new crush, wasn't exactly your favourite idea, but you needed a place, and your landlord wasn't about to give you time to find other options. Thank goodness you had gotten to know John and Mary, and eventually Sherlock, or else, who knows where you might be.

Sherlock's mouth fell open, and you smirked at his shock, "Cat's got your tongue?" You mocked his open mouth expression, forcing a shocked look into your eyes. 

Sherlock didn't say a word, he just stood up, walking behind John's chair, yet again, and leaning forward. You looked up at him with a small smile. Your nerves began to get the better of you and you slowly began to panic. What the heck did you do? Surely Sherlock didn't reciprocate your feelings, he couldn't, that's why it was so easy to tell him, you had already been rejected by him. He was a sociopath, so you knew he couldn-. 

Your thought's were cut off when Sherlock's lips locked with yours, and you let out a startled squeak. You pulled away, your eyes wide with shock, "What was that?" You laughed nervously.

"Honesly, (y/n), are you so daft that you don't even know what a kiss is?" He smiled smugly, before leaning down to kiss you again. "That," He whispered onto your lips, "was a kiss." 

You rolled your eyes, "Yes, I know what a kiss is, but why?" You shook your head, still a bit shocked.

Sherlock laughed, "I guess I'm not the only one who can't tell when their roommate has a crush on them."

 Your eyes widened, you thought they were gonna pop out of your skull, "I'm sorry, what?"

Sherlock sat back in his chair, moving back into his mind palace position, without saying a word. You just stared at him, unable to comprehend the words that had last left his lips. 

"You know, (y/n), it's very distracting when you stare at me." Sherlock smirked.
