Lady Helena

I have listened to Lady Helena's new session 'Sexual Shock' today. It's great! Lady Helena let me feel strong shocks with a level between pleasure and pain and this made me so horny! But there's another suggestion she gave me. Whenever I disobey her or try to cum without permission, I will feel a painful shock. Judging from how real the pleasure shocks felt, I can imagine, that this would not be fun.
I'm a little confused now. I'm in chastity for Princess Shelle, but I also have this suggestion from Lady Helena. I wonder if I have to get permission to cum from both of them now...
I have asked them in an email and I'm excited to receive an answer. It's a hot thought to serve both of them...
