A DMK Production
You have two sons. Hunter is twelve and Fisher is 13. You utilize spanking when the boys need to be punished. For about two years you have been using a belt to administer the boys' spankings with very good results. You do not spank bare and give Hunter and Fisher their spankings over whatever they happen to be wearing at the time. This has never been an issue before as either the boys are spanked separately or, if in trouble together, are dressed similarly.
This morning the boys are in trouble together and have earned a spanking. Hunter has already dressed for the day and is wearing a pair of thick denim shorts. Fisher has not dressed yet and is still in his pajama shorts (he isn't wearing any underwear.)
You come in with the belt and tell the boys they are being spanked and why. Fisher immediately starts protesting and says it isn't fair because the spanking will hurt him more since Hunter has more protection. Fisher refuses to cooperate. Hunter pipes in and says it is not a big deal that he knows it will hurt plenty over his shorts.
