The thirteenth installment of the BOY SLUT TRAINING series is entitled Jockstrap Slut Boy.  This suggestive file trains boy sluts to focus on the feelings associated with wearing a jockstrap as a symbol of submission and service.  You will associate the feeling you get of wearing a jockstrap with the pleasure you get from being dominated.  You will realize that wearing a jockstrap adds to your lust and is a sign of obedience.   Becoming a jockstrap slut boy makes you feel good and purposeful.  There will be a post-hypnotic suggestion within this file.  As always, Sir Voice welcomes your comments.  You can correspond directly with Sir Voice by using the direct message feature of this website.
