Feminized and Used by my Step-Mother: Caught, Locked, and Used

I know I'm going to be punished when my step-mother founds out what I've been doing with her panties — but I never could have expected what she had planned for me. She knows what I want better than I do, and she has plans for me.

And they all involve silk.

How far is she going to take this? Am I really going to be her pretty plaything all the time?
