In this clip Maria is in the bent over suspended position that she ended part 17 in. Obviously the ropes are very painful as she cannot quit complaining about how much they hurt - even knowing the probably consequence for making noise. Eventually Lew gets fed up with the noise and gets some rags to pack her mouth full of before tying more rags around her head to keep her quiet. He tests his new gag by several hard smacks and when satisfied resumes his torment of her, with his hand or a stick.
