Yes

You quickly remove the tape and take a step back. She stretches her mounth a bit and speaks: what would you like me to call you.... master?

This already confirmed a couple of things for you first of all, yes she was really a slave and second holy sh!t yes she was YOUR slave.

You look back at her, just call me by my name “[Bob]” whats yours?

Slave 2487

Well, thats a depressing answer. Let me ask you a different question then: what was your name before you became a slave?

Emma

Oke Emma and how long have you been a slave for?

30 years

Wow that long already?

She nods

That is long indeed, oke 1 final question before you can ask me some (you noticed she looked suprised at this)

I understand you became a slave willingly and so you get to choose every couple of years if you wish to stay a slave, how many years has it been since you where last asked? And how many years until you are asked again?

She hesitates to answer but ultimatly responds with: it has been 5 years since I was last asked and it will take another 20 until I am asked again.

.....

25 years, she has a contract of 25 years. Worst case scenario she would be stuck for over 9000 days of unwanted slavery.

Did your precious owner know this?

She shakes her head.

Well now im really curious about your story.
