Friends with a Sourwolf (Sterek)

(I DO NOT OWN TEEN WOLF OR ANY OF THE CHARACTERS) ⚠CONTAINS SMUT⚠
Stiles is convinced that Derek hates his guts, he's slammed into walls every other day, yelled at to shut up, and is always told that "you're not strong enough" or "your only human Stiles" because well it was partially true. Yeah he is human and maybe he is weak but who needs strength when you can trick the opponent? But then you come up and say shit to me like "Stiles you are the strongest and smartest person we've got in the pack" and damn, I don't have to be a werewolf to know that your heart rate picked up that whole sentence. Every. (thump, thump) Single. (Thump, Thump) Word. (THUMP, THUMP). Louder and louder. The echo of your lies. I was never part of this damn pack. Try to tell me that I'm lying, you're the one with the super hearing. So?
