Devotional Trousers
Devotional Trousers are some baggy or loose fitting trousers which have had one of the pockets cut out.
The Knight wears these trousers without any underwear.
His Princess is then able to put her hand into the pocket and touch and, if she wishes, play with his Desire.
Devotional Trousers are just one of the many special items a Knight can wear in public.
Wearing these trousers will feel very different to the Knight because he won't be wearing underwear. He will also be very aware that his Princess has the power to decide when she will use the pocket.
Within what her Knight is willing to allow happen, it is up to the Princess to decide when to touch him.
