I had an idea for a couple trapped on All Hallow's Eve in a small New England city. After their car breaks down, something seems mysterious about their mechanic. Before they know it, he knocks them unconscious and brings them to The Countess. A wicked vampiress who rules over the area with an iron fist. She orders them to be prepared for feast of the annual sacrifice. But they manage to escape. With no vehicle, they have to cross the many "terror"tories spanning all types of different monsters. Will they escape the clutches of the countess? Or will they be doomed to be eaten?!
I'd love to expand on any ideas you may have for it as well. We'd probably take turns dealing with NPC's if that's cool. You can create a few threats yourself! I was thinking it would be anywhere from Non-Con to Extreme depending on what kinks you'd like to explore.
