Hello, this is my first post here, so hello to everyone. Basically my girlfriend and I have been discussing our fantasies, and she really wants me to kidnap her and keep her as a slave for a while. My problem is, I want to kidnap her, by rendering her unconscious, so that she wakes captured and tied. My question are there any safe and simple ways to achieve this without having to resort to things such as chloroform? Thank you in advance for any advice, it is much appreciated.
