Just a random idea I've considered many times but what if when we hop on social media, pages like this, fetlife etc and make comments what if they had heavy consequences?
What if you are chatting with a gorgeous woman praising her body and how hot her giantess pictures are and you'd love to be eaten by her then you wake up the next morning in her cereal bowl.
Perhaps you are telling some lady how hot her soles are and you'd be her foot slave, next thing you know her giant sole is over head as she giggles and slowly brings it down onto your small body.
Maybe you make the offer you'd love to be that goddess's dildo then suddenly your six inches tall and heading in.
All of a sudden whatever we type online, whatever offer we make suddenly becomes reality.
Personally I think it would be hot, especially if it happened all at once imagine how many people would get the shock and pleasure of their lives and how guarded everyone would become once word got out.
