Have you been able to find any women into this? Love bulging bellies and bladders, just never thought of filling it this way

I would go with a inflatable dildo.

Shampoo/conditioner bottles that are long and narrow can be useful, if you're looking for non-sextoy options. Bubble wands like these:



can also be good (although I've only ever used them one at a time), as they are easy to clean and use. If you want sex toy recommendations, then inflatable plugs/dildos can be used vaginally but sometimes positioning them to stretch your entrance (which is what needs the long, slow stretching the most) can be tricky. Doc Johnson has some nice large toys, like the American Bombshell series, and I'm sure there are plenty of others for large dildos and such, you just may want to check out reviews regarding materials first. And then speculums can also be used for stretching, but I have no experience using them.
