Very dub con - warning's need to be read before downloading this fic...however I did like this as much as it is pretty dark. (view spoiler)[ Archive warning: I urge you to READ THIS WARNING because I'm just gonna tell ya that this fic is dark as shit and dubious consent isn't there to cover my ass.
Age is a serious thing here. In the present of the fic, Stiles is fifteen. HOWEVER, he flashes back to some one-sided (on his side) lust from much earlier in his life, where he is VERY underage. NO SEXUAL CONTACT happens before Stiles is fifteen, though.
Also, McCall is referenced as being physically abusive towards Scott on one occasion and it's left ambiguous as to whether he was to Melissa as well. (hide spoiler)]
