[M/FBprey4Fpred] Painful, Messy, yet Non-Fatal~?

Hoihoi! I've been hoping to experiment with something new! A cute little preything getting swallowed into a steaming, tight gut. Acids trying to melt him, muscles trying to crush him... and it being quite painful and even somewhat effectful~? Some skin burns, maybe some bones being snapped... but ultimately the prey ends up surviving? Stuck in a torturous gut at the whims of the pred, either being spat back out, pushed out the other end, or trapped forever in the churning gut~?

Bonus points if the prey is forced to endure all sorts of foods and drinks in there... having it all bubble on top of him before being drained away deeper into the pred's body~

Idk, maybe this is super weird😭 Hope atleast someone is interested in this!
