(custom, no names used)
Welcome, new slave girl! I'm so pleased My fellow Mistress gifted Me such a promising new servant! You look so ashamed and shy, just how I like them. I want you to strip for Me.
Surprise! You poor thing were born with a dick, and someone took your balls away! You're the only girl who has...or had, such equipment in the house. My initial reaction is to laugh and mock. I hear your previous mistress had you turned into a eunuch because you weren't submissive or obedient enough. I'm so happy to hear you were fixed.
You'll never get your balls back, you'll never be able to dominate a woman, and you'll always be a vulnerable, weak, submissive slave. You cannot get hard, but that's okay, because your tongue and fingers still work. But first, you'll be tasked with plenty of intimate jobs to do for Me and all My Mistress friends, like dressing, makeup, and hair.
I promise; the other slave girls and I won't let you forget that you're on the bottom of the hierarchy in the house!
