The setup is often elaborate, and some people ask why victims of premeditated sex don't realize ahead of time that it's coming, and take steps to prevent it. One must realize that a potential perpetrator knows the risks, and is actively taking measures to conceal his or her activities. Frequently, articles will be gathered and plans drawn up which are stored in a secret location, ready to be drawn upon quickly when the perpetrator is ready to spring the trap. Once alone, these articles and pre-made plans are quickly removed from concealment and set up, so that when the victim is lured into the bedroom, it comes as a complete surprise. There have been cases reported where a victim didn't realize what was happening until they were in the middle of the sexual act. By then, it is too late.
