I'm not sure what the brunette is being punished for, but the blonde girl would find herself over my knee for putting her feet up on Aunty'a furniture.
This is quite an unusual picture, with Dad having both girls over his knee at once, but I have to confess I like it and find it rather cute.
Now one sister watches her sibling get it, it's rather innovative having the spankee rest her hands on her sister's knees.
Oh the look on the blonde's face, she knows that her bottom will soon be toasted over Daddy's knee.
And yes there she is! A little teary even with her dress and panties on.
This is a marvelous shot, the redness of the panties contrasting nicely with the reddened legs around them and with a full view of sis' simmering globes.
This one is even better. The blonde sister is crying as her bare bottom is soundly spanked, while her sibling sneaks a peek from where she kneels. Is that a smile on her face?
The lungs open up and the legs kick. Wonderful! She is being taught a real lesson now.
And the fitting conclusion. Two soundly spanked young ladies kneel in the corners showing off their glowing red bottoms.
