I am an experienced femdom from the north, specialising in online education. By entering my profile, you have already taken the first step into your new life. From now on, you will obey unconditionally and follow my every word.
Step by step, I will mould you into my remote-controlled puppet and use you exactly as I wish. I know exactly what I want - and what I don't want. If your character does not meet my standards or you lack respect for your place far below me, I will cast you out without hesitation.
If, on the other hand, you show that you are worthy of me, you will serve me as I determine - according to my ideas, at my pace. Whether in the chat or in front of the camera, for an intensive education or a brief thrill: I expect you to always clearly recognise who has absolute control here.
