In great likelihood any given fic I post will have drinking or drug abuse. Intoxicated sex, swearing, existentialism, and unreliable narrators are also a given.
Often enough I have breath-play, different forms of erotic asphyxiation, and rough sex. This makes it sound like I write a lot of porn. I do not. Don't get too excited.
The thing people complain the most about in my fic is the typos. There are many; they are often comical. This is all because I don't use a beta anymore--don't emulate this practice.
Things you are unlikely to see in my fic: actual bdsm, non-con, adult/underage, intentional mind games, self-harm (unless drinking/drugs count) or bestiality/animal cruelty. I also do not kill off characters anymore.
The exception to almost all of this is my bandpires (gerard will most certainly hurt you tag) series which is a horror novella. It's horror, that means it has: bloodplay, ultra-violence, character death, black humor, angst out the wazoo, and all kinds of dubious consent around sex.
