“Start the video off with having the giantess ‘find’ the POV viewer below them. With mock concern she asks the lone tiny what is wrong, and when the tiny man explains he can’t find his people, she says something like. “Oh, I think I could maybe help you find them...” while ominously licking her lips and rubbing her belly. The first short minute or two continues like this, the giantess pretending to be concerned for the little tiny.
Then the cruel giantess reveals the truth to the tiny man. She ate everyone and everything, the tiny man is the literally the last of his people and now he’s...

Then the cruel giantess reveals the truth to the tiny man. She ate everyone and everything, the tiny man is the literally the last of his people and now he’s just going to be a final dessert to this gluttonous giantess. The giantess spends the main section of the video gloating and teasing the last survivor with her belly and about how she ate everyone.

For the dialogue, really just give me the impression that this giantess cares for nothing other than filling her belly. My dialogue requests:

The giantess talks about her bulging belly a lot, rubbing it, showing it off and talking about the sheer amount of squirming people in there now and how many were in there before but have long since been digested.

She talks about digestion and how powerful her stomach is, melting and crushing everything inside it. The giantess would visit this civilization every day and stuff herself to bursting, and then go and hide to digest so her belly was flat and ready for the next day.

Talk about how this current bulging tummy is full of the last of this entire people group. She could have paced herself, but she didn’t. If it wasn’t for her gluttony, they would still exist.

Sometimes she even swallowed buildings and cars, unhinging her jaw and shoving them down.

Please use words like: Tummy, belly, stomach and gut a lot.
