Levi x Reader: Yes Sir

The Scouts

Levi turns to look at you.
"The commander is dead."
The screams of the scouts had stopped. They were all dead. Your mind flashes back to your hallucinations. No. This was different your friends are still alive. But they're the only ones. The beast titan had sent pure titans and had demolished all the cities. We were screwed. So screwed.
You look at him terror in your eyes, "everyone's dead!"
"Our squad is still out there on the other side of the walls. We have to help them."
You couldn't believe this. You had the upper hand. And yet here you were. Eren had just sealed the hole in the wall. Reiner's titan was down for now, but Bertholdt was still up and fighting. There are a few titans you can kill to help your squad. This is all that's left of the scout regiment, all that's left of the people of the walls. You won't let anyone else die. You and Levi use your ODM gear and fly through the air near buildings slicing off titans' napes. The way you two worked together was rhythmic and almost like a dance. Armin appears beside you both.
"Captain! How is it on the other side?"
Silence. Levi simply stares at Armin.
You see tears full Armin's eyes.
"I know Armin. But we don't mourn until the fight is over."
"Right."
You three split up.
You take on this titan. It's a creepy looking one...with a huge smile on its face. Your mind wanders thinking about who this titan used to be. You push the thought away. "They're gone now" you tell yourself. You use your gear to pierce its skin on the shoulder and swing up towards the back of its head. The titan makes an abrupt movement grabbing you in its hands.
"What the hell?"
Before you can think twice, you're staring into a titan's mouth, an ugly s.o.b. titan to be exact, but that's not the point. The point is, you're about to die. After everything you've been through your life is about to end. You imagine your friends faces smiling as you grew up together and how those smiles have faded. You imagine how those smiles might never show again after this if you die. Levi rarely smiles at all in the first place, but after this. No. No. You refuse to go out like this. This isn't what you want it is not your time to go.

The titan increases his harsh grip on you. Your lungs burn as they are being crushed. You can barely see as tears blur your eyes. You reach for your blade but you can't get to it because of this stupid titan. You screamed into its face, but soon regretting so because your vision darkened and your head felt heavy. You began to lose consciousness as the oxygen so necessary was being deprived of you. You thought, "is this seriously how I'm going to die?"
It raises its arm towards its mouth and now you're in it. You hold your arms up to keep the mouth open. You look out beyond its teeth and see your squad members. Levi cuts out a nape of a small titan and then looks in your direction. Your gaze meets his and his eyes widen. Immediately he flies towards you, but it's too late. You're not strong enough and he wasn't fast enough. The mouth closes and you slide down its throat. You scream and fall down. Complete darkness and constricting surroundings increase the claustrophobia you now feel. After sliding down for what felt like hours you end up in a pool of something. It burns. You gasp. "Am I in its stomach?" you ask yourself. You can't die like this. Being eaten alive...no that's not how you will go out. You look around and see body parts floating in the acid. You have to get out. You scream as the fear overtakes you.

Levi stands frozen. Armin is standing beside him. They both stare at each other in shock. They try to move, but their bodies don't let them. Around them the others not knowing of the situation continue fighting. Levi finally yells out and uses his gear to propel himself to the titan. He quickly kills the beast and watches it fall down to the ground. Armin thinks he sees tears in his eyes. Blood covers Levi's face. He just stands there staring at the titan. He falls to his knees.

You look at your gear and pull out your extra blades. "Please work please work..."
You fiercely use your blades to cut through the titan's skin. You stab it over and over again. You see light.
"Come on please"
You picture Levi's face and the rest of your squad and scream out throwing one last cut into the stomach and then you're poured out of the titan. You crawl onto the ground coughing and gasping for air. You lay there and then see a shadow above you. Then you feel arms around you. You look up and see Levi holding you.
"I told you Levi. I'm not dying."
He picks you up and uses his gear to take you to higher ground. Armin is there and he calls out your name.
"Y/n you're alive!"
You stand up beside them and give a weak smile.
"I'm not going anywhere you guys."
Your mind is racing. You almost died, but here you are. The fight isn't over. You take in a deep sigh looking over at your comrades, your friends.
"Let's finish this once and for all" Levi says, but is interrupted by an earth shattering slam.
