An excellent short fanfic told from Stiles' pov. Stiles is forced to mate with Peter to save him from the dark influence of the Nemeton. Peter plays the good guy in this fic.
'The threat was implicit and the Sheriff's gun hand was twitching, even though his guns were locked away in their safe, while his eyes were locked on Peter.
"He saved my life."
"What. Did. He. Do."
"Um...wehadtohavesextosetthebond," Stiles mumbled.'
