OK, my favorite method of inflation is air pump, where you insert a tube connected to an aquarium air pump (commonly used for fish tanks) up your bum and inflate your belly with air. I have several short clips of me doing this in my videos on this site and longer videos on YouTube (my username on YouTube is 'Edgar Allan Poe". It is not to be done without care, as you are essentially pushing air through your intestines to Bloat your stomach, so a controlled air pump is much safer than a foot pump (the ones that you use for inflating bike tyres). With practice you can inflate your belly to a massive size.
Moderation: Okay. Can I expect quite a big belly, then? Bigger, the better
Yes, almost all of my photos on this site including my profile pic are taken after an air pump inflation. Having said that, you have to stretch your belly to a big size over time. I've been doing this for a while and at the start I could t get very big so I bloated my stomach with coke and Mentos and now I can get to a massive size when I inflate
I dont inflate often these days, coke and Mentos is what I use now, its just simpler and safer, and you get the same results
Oh ok shouldn't be a problem then. There's some good "how to inflate" vids online that would be helpful. I only have videos of me after I've already started inflating. I tried water pump bloating but I'm not doing it again. Too complicated.
