That Alpha/Omega Thing
Stiles is a human Omega, in a society that treats Omegas as baby factories.
Derek is a werewolf Alpha, and werewolf society treats Omegas much differently.
When Stiles goes into his first heat, he’s expecting to be thrown against the ground and fucked until he can’t remember his own name. He was not expecting Derek to lock him alone inside a room and keep everyone outside until it passes and everyone can think logically again.
