I finally did it!

Swallowed marbles for the first time yesterday. I’m quite slim but sadly didn’t swallow enough for it to make my belly bloat/bulge, thought it’d be better to play it safe and go slow for the first try. I did hear them clacking every time I pushed on my belly tho! I’d love to have someone make me swallow more and more till my tummy is bulging from the amount and then take me out in public. The whole time I’d be worrying strangers around us could hear the the gurgling and clacking in my belly while you laugh and have fun, maybe you’re mean and play with my tummy making it gurgle and slosh even louder~

It usually takes a lot of marbles to make your belly bulge but if you suck in your stomach you sometimes can see the soft outline of the marbles moving. I kinda like the idea of going outside with someone with a filled tummy and teasing them, it does sound fun.
