You have three boys. Two are grown and have moved out on their own. Your youngest son is named Phillip and he is thirteen. (just last week)
Phillip is a good boy, (his brothers say spoiled) you only have to spank him about every six weeks or so.
He is a little sensitive so when he's earned a spanking he stays in line for a long time. (not the same experience with your older two). You have always spanked him pants down over you knee with your hand. It doesn't take long before he is crying the tears of a boy whose really sorry.
There is an unwritten rule. (you've not spoken the rule out loud in years) The rule is when the boy turns thirteen he no longer gets spanked with your hand but with the belt. You remember moving to the belt with the older two because your hand really wasn't very effective.
Well Phillip is due a spanking tonight. Though you've not told him, "hey when you're thirteen you get the belt", he has been teased but his brothers that he will soon feel your belt.
You go to his room to spank him. The boy looks terrified. What do you do?
