i am guessing and it is a guess sorry that you mean scenarios, as in predicaments that you may find yourself in where by bondage might be able to be incorporated within the role play, such as kidnap, forced abduction etc, maybe interrogation, or how about overzealous and bad cop, arresting you and using bondage to restrain and have their way etc, if i have got the right end of the stick then it is scenarios that he is looking for you to identify and develop, could be school teacher and busty 6th former there are many many possibilities, maybe if you got him to confirm if this is the sort of thing he is after we could throw some ideas down.

Hope this helps
