Raoul, Lord of the Castle, is administering a severe spanking to his young wife, Bess, with the intention of quelling her defiance.
He spanked both buttocks together and he spanked them separately, sometimes alternating and sometimes giving a session all on one buttock followed by a session on the other. He didn’t speak, but the sound of the spanking was like a language all by itself.
Added to which, of course, were the sounds that Bess made. At first she remained stonily silent. She tightened her buttocks to lessen the impact. But as the spanking progressed, she was no longer able to maintain the tension and so was forced to relax, which meant that the sound of the blows became louder at the same time as her pain increased.
