When Jack goes to his doctor for a routine physical, the new intern catches him stealing blank prescription forms. Since he's already undressed, it's easy for the young doctor to just slide him over his knee and deliver a long, hard spanking. When the attending physician interrupts, Jack is stark naked with a very red butt. The doc decides that the intern needs a "taste of his own medicine". By the time he is finished, both boys are naked, with burning red asses "“ and begging the doctor to stop.

This is a good old-fashioned OTK hand spanking by a relentless authority figure.
