Oooya! Where do I begin?
It’s the usual suspects when it comes to one’s size discovery; honey I shurnk the kids/ourselves. I especially loved the vore-ish scenes like the classic cereal vore scene from HISTK (link: https://www.youtube.com/watch?v=v-vNO6BXiiI) and the dipping vore scene with multiple giantess teens (Link to an fan made vore cut cause I couldn’t find the original (CW: M/F vore): https://www.youtube.com/watch?v=r5eflsMwSXE)
But then there are more obscure ones like that one scene in Krypto the Superdog where the Krypto’s owner (along with the aliens who shrunk them) nearly got eaten by the owner’s little sister, GOSH that awakened somethin’ in me!
Other obscure size-fantasy sources include: A giantess scene in Danny Phantom, An episode in El Tigre where the main character got casually tossed in a giant green man’s gaping maw. A scene In Aaah Monsters where the two main characters had to go an endo journey inside their female monster friend, ect.
If you couldn’t tell by now, I’m a HUGE vore fan when it comes to size, especially when the pred (preferably male nowadays) is dominating their tiny mouth resident.
