Use a stack for this practice. It is a flexible and resilient flogging device consisting of a rigid handle, a thin bar (metal, silicone or plastic) and a flap at the end. The flap can be in the form of a heart, a hand, a cross or a regular square shape, with lacing and other decorations. A stack is used for flogging and guiding the caresses gracefully.
Assume a comfortable position and point the stack to places that require worshipping. You can do it silently or by verbal instruction.
Raise the bar: agree that you will slap your partner slightly on the buttocks if he/she misses your instruction or does it incorrectly.
