Not a word of scolding. What a shame. Why is he being spanked? How can he prevent another session next time. Count the strokes. Engage him to make him think how he broke your rules and why he is being disciplined. Than have him thank you for the correction.
Very similarly to my wife except mine is verbal as well. And she makes sure to spank my balls as well. I'm made to push the up towards my butt and hold my legs together so the balls stay exposed.
