Your have been his "dad" (he calls you dad) for about six months since you married his mom. Tristen is 13 going on 14. You are away on business when Tristen gets into trouble because he missed the bus after school for the third time. Your spouse promised the next time she had to pick him up because he missed the bus he would be in "big trouble". Big trouble for Tristen is being grounded for two weeks.
Grounding means no outside activities and going to bed early without the use of any games or devices. (after school work is done). You've always offered to tan Tristen's butt instead but you told him once he switches over you will decide when he can go back.
Tristen has a school function later tonight and he doesn't want to miss it so he calls you and says he will take the spanking when you get home tomorrow. Well everyone has agreed and Tristen goes to his event and you come home the next day.
Looks like the boy has changed his mind? Now what?
