Me and the Devil
Mycroft Holmes x ExSpy!Reader
Synopsis: You were an ex-spy who needed to fly under the radar to stay safe, and he? He was the Devil.
A/n: As I grow older, the older Holmes becomes my cup of tea. Love me a man with power.
“I’m sorry, what are we doing exactly?”
Your worried tone disturbed John but did nothing to deter Sherlock from what he was about to do. “I’m getting us into a military base with Mycroft's identity. What does it look like we are doing?”
John’s eyes widened as he finally understood what was happening. “Sherlock, you look nothing like your brother,” John stated as they rolled up to the military gate. Glancing back at you, John caught sight of you rubbing your face roughly between your fingers, “We are so fucked” you whispered to yourself. There was no stopping this train wreck; you were just hopeful the Mycroft would forgive you for what you were about to allow to happen.

After being in the lab for 15 minutes, you were ‘politely’ escorted out. Upon reaching the outside and, in turn, a cell tour, your phone began blowing up with messages and missed calls. You knew exactly who they were from before even looking at them, but you didn’t exactly expect the type of message you got.
‘Return to London now before I send someone to fetch you. I am not playing this game anymore.’
Your stomach twists as you read the message over and over. Mycroft was never kidding, and you knew firsthand that he would indeed send someone to get you if you didn't listen. It's happened a fair number of times…
Sherlock and John looked at you quizically. “Thanks, boys,” you snapped as you stormed over to the car that Mycroft most certainly sent for you. “I must return to London to pay for a situation you two put me in... Once again.”
John tried to apologize, but Sherlock cut him off, “You could always choose not to listen to him. I do it all the time.”
You laughed at his words as you ripped open the door. “You don't know this side of your brother, my dear friend. I will see you two in a few days.”

The receptionist barely acknowledged you as you trudged in with your bags, the fact that he wouldn’t even let you head home first pissed you off to no extent causing your patience to dwindle quickly. “Excuse me, is Mycroft in his office?”
The receptionist stopped typing, throwing an icy glare up at you before she finally took in your disheveled form. She popped her gum between her teeth, her icy glare flicking back up to you before resuming her typing. You let out a humorless laugh at her blatantly rude behavior, “Alright, I’ll go check for myself then-”
“You take one more step, and I’m calling security.”
You halted in your tracks, eyes wide in disbelief as you tried your best not to rip her head off. “You’re kidding, right?” you whispered angrily, practically begging her to repeat what she said so you could lose your temper right then and there. Silence hung heavy and tense in the air; at this point, some of the people in the lobby were throwing glances at one another in shock of possibly seeing violence.
She said nothing but popped her gum once more up at you.
Deciding to ignore her and just find him yourself, you continue towards the doors behind the desk. The receptionist flies from her seat to stop you, but you manage to hit her in the knees with your luggage. It gave you a few seconds to slip behind the door and take off down the corridor towards the direction of Mycroft's office. The receptionist screamed for security, and you feared that if you didn’t find Mycroft soon, he’d have to fetch you from a jail cell. Rounding the corner, you came face to face with the Devil himself, who seemed to have been roused by the yelling of the guards behind you.
“Why must you always get in trouble?”
You scoffed up at him before shoving him in anger, your fuse finally being ignited. The guards finally rounded the corner just as you had shoved him, but before they could grab you, Mycroft put up a hand, “She's with me, shes just being a brat.”
“I AM NOT” you screamed back, face growing warm from now both embarrassment and rage. The receptionist came into view, popping her stupid gum as she took in the scene smugly. Your eyes narrowed at her. “You should keep your pet in check, Mr Holmes. She could be a real danger to society if not.”
The words stung, and you started to lunge at her, but Mycroft, as well as the guards, held you back. “Leave, all of you!” Mycroft snapped out before hauling you towards his office, having quite enough of your temper for the day.
“You’re just going to let her talk to me like that?! She humiliated me, Mycroft,” you cried out as the doors of his office slammed shut behind him. Tears formed along your lash line as the anger and sadness filled your veins. Mycroft ignores you as he moves toward his desk. “Do you think this is a game?”
Your eyebrows furrowed in confusion before once again realizing why you were here, he didn’t care if your feelings were hurt right now, for he was far too angry with you to care. The more you watched him move, the more you saw just how angry he was, but you knew that behind that anger was fear. Wiping your eyes, you moved slowly towards his desk as he sat down. “I didn’t make that decision, Mycroft-”
“You need to stay away from my brother.”
The sound of your breath getting caught in your throat was louder than you intended. “You’ve allowed me to live with Sherlock for 3 years now. I have done far more reckless actions in those three years, so why the sudden change of heart?”
Mycroft rubbed at his temple in exasperation and stress. You could visibly see just how stressed he was over this entire thing, making you worry that maybe you did cross the line, even when it wasn’t your choice. You turned his chair slightly before sitting on his lap sideways, “Whats going on?” you stated softly as you gently pulled his hands from his face, moving them to wrap around you instead, one of your hands stayed on the one you rested in your lap, fingers trailing sweetly up and down the skin below.
“You are supposed to lay low. To stay out of danger. Now that Sherlock is getting more attention, I fear that the task will be impossible, and my job is to protect you from that.”
Sadness once again wormed its way into your chest as you thought through what to do or where to go. “I can try and find a place-”
He laughed softly at you before rubbing his face once more in exasperation, “Oh my dear, sometimes you’re blind to unasked questions.”
“Well, we’ve only just begun dating again. I would have found it rude to assume! Besides, I’m still mad at you for not defending me out there.” Your lips curled up into a fake pout, causing him to laugh some more at your childishness. “I'm not kidding, Mycroft!” you hissed as you shoved his chest playfully. He wrapped a hand around your wrist, keeping you where you were. “Would you like me to fire her or feed her to the wolves, my Darling?” his teasing tone almost caused you to falter and melt, but you kept your stone-like demeanor in check, “The wolves… Mr Holmes. The wolves.”
Mycroft let go of your wrist and reached for the phone on his desk. “What are you doing?” You questioned as the sound of ringing filled the room.
“Feeding her to the wolves, of course. I’m also summoning the car for us so we can go home.”
