Happy to report that david emerged completely unscathed from his ordeal on the stool. He reported that he felt the after effects for two whole days on his butt and balls. The tip of his penis got it the worst, though, and it took him until yesterday to get back to fighting form.
He complained about soreness right where that arrow is, though I inspected it closely and could see no visible damage. It was too sore for him to rub it for a couple of days. Poor baby. I did kiss it better, of course.
I told him we would take him to see our doctor if it was not better in a few days and she could make a close inspection of it.
Imagine how embarrassed he would be explaining what happened. I would probably have had to jump in and explain for him. You know, about the masturbating without permission, and the inevitable punishment that followed. The spanking, the stool and sandpaper... Ha Ha!
Fortunately, it's all better now. david came and asked me for my permissions to jerk off, and then reported back that all was in fully functioning condition (yummy yummy into his tummy).
I might have to tape up his cocktip with duct tape next time he gets stooled.
