Burn her flesh with a candle from the table
From Lord Of Utterdom
You peel away her clothing, revealing her bare breasts. You pin her to a table with your hand and as she squirms, you lift the candle. You drip the hot wax across her nipples, and she groans in anguish, squirming and kicking. A few more drops, and the groans sound different. Her eyes roll upwards as the wax cools and hardens against her thick red nipples. Her kicking lessens, and her legs seem to writher instead.
"You're enjoying this?!" You ask, confused. "This is torture, you sow!"
"More, my prince, and I will reveal anything you ask!"
Fuck this. Head out and go elsewhere amongst the castle
