Big Brother.(Levi x sister! reader)
(Warning: This is an eventual incest!!!! If you dont like Incest then please dont read! you have been warned!!)
You and your brother Levi were so close when you was only 4 years old. You loved your big brother who always protected you in the flithy undergrounds, but one day he left and never returned. You had to grow up undergrounds by yourself...and had to become strong by yourself. Later on in life you became the most feared thug underground, but one day people with capes with wings on their backs try to take you into the 'survey corps'. You were against it...Its not like you were scared of Titans, you just didnt want to see him again. The one you 'called' brother. But you had to accept..you had someone to kill.
