My Demon, My Slave (Antiseptiplier)
Now, this is not a happy story. There's no flowers and heart-shaped chocolates. No rings, no love... no restrictions.
This series contains (or will contain) gay male sexuality, demons, BDSM and bondage. Throughout the series there may be instances of non-consensual sex and/or reluctance. If any of this makes you uncomfortable, do not continue on. You've been warned.
So, to put it lightly, Antiseptiplier smut for the most hardcore of readers. No complaints. I gave you a fair warning. Now, on with the story!
