You will remain bent until I am finished because your discomfort does not set the length of the session. Each strike is a reminder that your ass exists for correction and for my satisfaction, not for your relief. The redness spreads because I decide how thoroughly the lesson is delivered. You do not ask for it to stop and you do not count the strikes as if numbers give you control. Discipline requires that you take what is given and remain useful afterward. The training continues until I choose to end it.
