1. When I was younger (12-13). I made the stupid mistake of saving my vore stuff on the family PC. So when my mom was trying to download something, she clicked "save as". This immediately brought up my folder. With the first pictures being of a giantess swallowing a tiny girl. She called me over and asked what the hell it was. My mom knew I download torrents to watch movies and TV shows. So I quickly came up the the excuse, "uh, it must have downloaded with one of the torrents by mistake." I quickly deleted it while making comments about how "weird and messed up" the pictures were to sell the excuse. I was petrified for days that she would bring it up again. Thankfully she did not.
2. A little older (14-15). I had my own computer at this point. One night, I left my laptop by my bed with my headphones on. While leaving vore videos on loop. I think kid me was trying to induce a vore dream, but I'm not sure. Then that night OF ALL NIGHTS, my mom unlocked my door to get something and saw what was playing. She woke me and asked what I was watching. I froze for a moment and told her I fell asleep watching YouTube and the videos must have just played (even though I was using Windows Media Player, but she didn't know that). I closed my computer and she grabbed her thing and left. I probed her about it the next day to make sure she didn't know, but thankfully she had already forgotten.
3. This was a little later after 2. My brother came into my room and asked why "cannibal" videos were in my suggested videos on YouTube. I didn't realize he used my account sometimes. I told him I let my friend use it so he could watch videos without his parents knowing. My brother bought it, but then told me I should stay away from that friend and that he is probably dangerous. Which I admit, that comment hurt me a bit.

After that, I didn't play loose anymore. I started using only anonymous accounts that no one else had access to, I made sure my vore stuff was hidden deep on my computer, I made sure everything was closed when I wasn't using it, and I set up "save as" to only open my downloads folder. Haven't had another close call since. How about you?
