Cleo has been a very naughty girl. To punish her, Bob ties her to a barstool, lifts her skirt and starts to spank her. When he sees that she enjoys that a bit to much, he gets an assortment of mess to punish her even more.
He starts to cover her curvy bum with nutella, then pies it and pours custard over it for good measure. He then lifts her top and covers her back and boobs with nutella and custard. When he sees that she still enjoys the treatment to much, he pies her in the face and pours a liter of custard over her head.
A second pies is pushed into Cleo's face for good measure, followed by some more custard. The scene ends with a bucket of xanthan gunge poured over poor Cleo.
