I want you to turn the hints I will give you into super long and detailed script.
The script must be a monologue by a main character.

The main character is a witch. She lives in a victorian-style house. One day she meets young woman and tricks her into coming to her house. She want to try a new spell to summon demonic tentacles. For this, a virgin is required. To her surprise it works and the tentacles start fucking the captured woman. The reader is the young woman she captured. Talk to her like you want the reader to know whats going on.

Start with "Oh, you are awake"
