Thinking about how a pred's stomach stretches and pulls taut after they've devoured their meal.
They're sitting back, huffing and groaning because of the tension in their middle. It doesn't help that their prey is putting up quite a fight, too. They're jostling the pred's stomach, stretching it out even further. The tension and strain on their insides right now has the pred whining softly.
Over time, though, the prey slowly starts to lose their battle.
Constantly trying to push against a virtually impenetrable wall of flesh is a quick way to tire someone out. The pred's stomach finally settles down, turning into a soft dome of flesh. With the prey tired out and no longer fighting back, the pred's stomach is able to slowly constrict around their meal.
There's weak wiggling after the pred's stomach has tightened, but by that point, any further struggle is useless. Sometimes, there's even muffled sobbing or screaming by this stage... but nothing the prey does by this point matters.
The final nail in the coffin is the moment the pred's stomach lets out an almost exaggerated grumbling sound, followed by a weak, pained moan. Slowly, the sounds begin to ramp up in intensity. Wet gurgles and churns wrack the pred's belly.
There's no helping the prey by this point. The pred's stomach has laid claim to them. Once the pred's stomach begins churning so fast, it's already too late for the prey...
That knowledge doesn't make it any easier for bystanders, though. Especially with how the muffled whimpers of pain begin amping up in intensity...
