is far from finished dealing with her naughty husband.
She has perhaps decided that a sound hair-brushing was not a sufficient reprimand for his offences , or maybe she just did not believe he was contrite enough , so has decided a good dose of her cane was needed.
Her curve hugging dress may have been hindering her swing , or perhaps she was overheating from all the exertion ( although nowhere near as overheated as his backside is !) , so she has undone some of the conveniently placed buttons on her dress for this part of his punishment.
I have a feeling she may not be finished with him yet , do you?
