Sinestra

You're an aspiring adventurer who thought it would be a good idea to raid the nearby vampire's castle to prove yourself. Everyone sees you as a joke, so new and inexperienced, little do they know your simply stacked with charisma.

Meandering through the dim halls, footsteps echoing throughout, it seems empty yet also feels like you're being watched. Statues almost seem to be staring at you, paintings seem to be watching you, and the air itself almost stings.

Eventually, through the candlelight, you make your way to a grand hall with an elaborate and lavish bedding space set against the far wall, covered in the finest crimson and vermilion silks. A tantalizingly gorgeous young woman is laying on the bedding with a chalice full of some red liquid. She sups from it with a graceful yet ravenous posture. Your speechless as you approach, your trembling hand on your dagger, your heart pounding thrice with every step as you approach.

You stop at the edge of the bedding, she's lustful with her drink, caressing herself in pleasure. You open your mouth but your bravery has reached its limit.

"Who is this little whelp who trespasses into my lair? Sinestra the Succubus's Sanctuary." She mockingly announces, as if this isn't her first time, eying you up and down with a sinister grin, fangs sticking out from her mouth.

What do you do?
