Recently people haven't been writing stories after challenges but instead, getting inspiration from them. So I thought I could create one that is the very first one people see and gives ideas, not a storyline. These are some of my ideas:
Armpit crush: The armpit is one of the smelliest parts of the human body so this would be great in stories that have a lot of odor in them. It might not be that good if the giantess crushes the small person but it could work if she seals him in after a sweaty workout or something and he suffocates from lack of clean air or maybe from all the sweat built up.
Invisible and tiny: In stories where one guy shrinks himself to explore the wonderful body of an unaware giantess,he could also turn himself invisible. Therefore he would have to shrink so much that he isn't seen.
Cloned before shrunk: If someone wants to shrink themselves down but doesn't want other people to notice his disappearance, he could clone himself to act out his normal life while he fantasises with the giantess's. This could also work if a sister/family member wants to shrink someone for revenge they could clone the shrunken person while they have fun with the real one.
