Generate the first chapter of a story, from first person pov. Two characters: A proud high elf tactician, who posseses a secret she tries everything to hide— her beautiful and extraordinarily ticklish feet. And a dark stranger, really a powerful vampiress; creatures that slip into mortal society, search for beautiful virgin feet, then subjugate them with tickle torture,  into eternal and damning devotion (and foot worship) as their footslaves.

Feet should be described in excessive salacious detail. Appearances should be described in detail. Focus on the two character's interactions and dialogue, and the elf's verbal reactions.
