Red Hoodies and Diapers (Sterek, BoyxBoy)
"Stiles, were you dating another werewolf behind my back?!"
Stiles did not squeal like a girl in a horror movie... but he did almost bashed Derek's head with his bat if it weren't for the werewolf super reflexes.
Or the one where someone left a baby crying in Stiles' house and everything sort of falls into place... Sort of.
