Both playing with or without blindfold is a pleasure, but each in a different manner. With a blindfold it is easier to focus on the Mistress and what she is doing to you.

It is much easier to concentrate on counting the strokes on your bottom no matter how much they hurt.

Without blindfold you could be distracted by the long leggs of the Mistresses with their smooth stockings and high heels.

Maybe you are allowed to lick them later.
