Personal singer

"Dorothea, anytime you are in this trance, you will become my personal and mindless opera singer. You'll sing just as you are doing now, and anytime you finish a song you will simply move on to the next song without pause. Also, I can change the song you're singing whenever I fuck your pussy."

Dorothea kept singing, the cum leaking to the floor now.

"When you are out of trance, you will do everything you can to advertise the collars. I can get you in and out of trance with a snap of my fingers, and I want you to return to my room every night."
