All the way back in 2018 I saved this comment from bbw-chan. I never tried this, but it might be helpful.
>Yeah just started browsing this site again,I was the one using trashbags and gel out of diapers, works get you can get the gel in bulk too makes it perfectly squishy and holds in spot
>What I did was put 5 trash bags inside one another filled the most inner one with water then add the gel till I was happy with the consistency tied each bag off individualy and cut the ties off(I found that the tough guard bags worked the best most water resistant lol) ten after that found a huge pair of leggings and used the legs as covers for the bag after it's filled to help avoid punctures
>I'd take pic of the proccess but not in a situation I can do that right now
>I was able to make a 4 gallon bag with no worries and could lean up against things even sat on a couple bags I made with that method too
>Was a awesome way to figure out how it would feel to be that heavy lol, I think I weighed around 600lbs with all bags i had at one time coould barely move around
>That was a fun night coudnt stay dry if you know what I mean lol, even got some precum coming out as I remember that typing it out lol
