If you're one of the lucky who have incorporated DD into your marriage later in life, or after the kids have moved away from home - I can only say what a freedom it is!
No worrying about the kids hearing mommy being spanked.
No trouble with corner-time and the kids coming in seeing mommy naked or with her panties down around her ankles standing in a corner contemplating the reason for her discipline!
Not having to worry if the implement your HOH has decided to spank you with is noisy or not.
If you feel the immediate need for maintenance - you can pull down your panties and be maintained right then and there on the spot!
The freedom of a whole house to yourself is fantastic!
I've done my mommy duty - and am now enjoying the joys of wife duty!
Hugs from a happy sub!
