Mistress Gaia wanted to humiliate her slave as he ironed. So she used her farts to do it. She was in the same room as him and she farted silently and she filled the entire room with her farts. He could tell she had farted but he could not do anything about it. He could not ask her about it, he could not laugh and he could not act disgusted. He had to smell the farts in silence.
