Quinn is returned to you by the local police. Naturally, you decide that he's going to have to get a spanking for this. But not just a regular spanking. You see, until this date, Quinn has only ever been spanked by hand. This time though, it's serious. So you're going to use the hairbrush.
Quinn looks very worried as you explain this to him. He's no stranger to being spanked, but the hairbrush is a new and scary thing for him. You put him across your knee, lower his pants, and give his bare little bottom a few steady whacks.
You start quite slow, spanking him steadily, when as you get about halfway through, Quinn's tears start to flow far more freely. Within the next few smacks, he is sobbing and bawling more than he ever has before, and you haven't seen him cry so much during a spanking in some years.
You know that, for a hairbrush spanking, you are not giving it unduly harsh. The shade of red on his bottom certainly is still relatively pale. But Quinn's reaction is more than you had expected. He is now pleading with you, "Please daddy, I'm sorry! It hurts too much!" You are only about halfway through what you'd gauge as a proper, normal hairbrush spanking.
What do you do now?
