Deanna has allowed Bart to come out on her boat for a day as her first mate. But Bart has not done the chores she assigned him and even had the audacity to drink some of her beers. Deanna puts Bart over her knee and gives him a hand spanking before moving on to the leather strap and a huge paddle. After blistering his ass she makes him hold on to a rail on the boat as she informs him that this is her method of "walking the plank" She whips him until he can no longer hold on and Bart falls into the water as Deanna laughs at him.
