Correcting a slut wife

Mine needs attitude adjustment as she likes to think she`s in control and has a big mouth as well...True like a lot of them these days.
Also i have a big spanking fetish and she`s taken a lot in the past...always for money though.I`m unlikely to see those scenarios again.Pity as there`s nothing like a nice arse being thrashed especially when it`s tied up and there`s no where to hide.
