I'll share some from when I was a kid and a few recent ones
when I was a kid I would act out a lot of vore fantasies (I didn't know that's what they where at the time tho). my childhood friend and I would scatter toys all over the floor and walk around on all fours, putting them in our shirts pretending to swallow them. Sadly I haven't talked to them in years, but thinking back on it they where probably into vore too, we did this a lot, and especially with stuffed animals. I also liked to play with goldfish with another friend of mine and pretend we where monsters and they where our victims. I also remember a time in daycare when I was like 11 or 12 where I came in an chugged water from the fountain, and then layed down and listened to the sounds as I sloshed my belly around and being very intrigued, and even got a few friends to do it.
My adult ones have sadly not been many with other people, but one time when I was getting head from one of my friends, they swallowed gummies and water for me a bunch and I came 4 times in 10 minutes. I've also regularly swallowed gummies whole and might even try something living sometime like a really small turtle frog
