Sara2001 I think this is a complete different way to maintain a relationship. I don't think it would fit to our lifestyle. For us, the existence of limitations and punishments are an aspect we enjoy very much. Both of us think it's very sexy that there are awfull consequences for her, if she doesn't act as expected. We often talk about it, we want this kind of pressure and structure in our relationship. We want to feel that I have much more power then she has, that things are no longer her free choice.
From what I can see, she is happier then ever in our dynamic and she is living under the strictest rules she ever had, much stricter then her mother's rules or any other setup that was ever used in her home. She makes very clear to me, that she likes the feeling of having a tough and very clear structure in her life and that she enjoys that she must only follow my rules and orders and doesn't have to worry much about other things.
Yes I think she is happier since she met you and so maybe this is the sort of relationship she needs. I would just throw in that you don't need to "feel" like you have more power over her you do have more power over her. After hearing about everything in your lives I think I could keep giving more of myself to my husband.
I would remind you that the most power my husband has over me is when he pleasures me. you should unlock Sara without any warning and give her a deep g-spot orgasm. Along with the surprise of being belted as ever one minute and then completely nude seconds later and then shaking and screaming a few minutes later and falling out of the chair I can confirm that your power would not be questioned at all. Love isn't a race to dominate Sarah more than her mother!
