Ugh... Thinking thoughts of all kinds of hunger sounds. I may love a thin, aching cavern but big soft bellies are my favorite too when they're empty. Though the sensation would be the same in my mind... The clenching groans, the loud complaints... the only difference is how it would feel to have that quaking flesh surround the sex one has. Imagine rutting against a thin, moaning gut, feeling it roar while your partner tries to squirm, all the while the vibrations make it feel just divine-- like the organ wants to devour the thing rubbing against it. Or how soft and pliable an empty, chubby, roaring stomach would be. Pressing against it, pumping your hips every time it groans to your partner's flushed sighs. Keeping food far far away to make it snarl louder...
