While it doesnt show a Giantess per-say you would be surprised to here exactly what she said. there's a really interesting conversation where the main character's girlfriend describes in detail how she wishes he was tiny so she could have him all to herself. She even goes on to say she would eventually eat him! None of this is really shown, but she describes it all with her hands. Here's the link. It's at the 9 minute mark.
