Tiger Trouble

You ignore the beast, it's going to eat you anyway, what's the point of helping it escape? The beast lies down. "Whatever, I'll see you tomorrow morning anyway." The tiger sleeps and you eventually fall asleep as well.

You are awoken by guards dragging you to your feet. They lead you to a gate that leads to a large arena. Spectators cheer as you are tossed out onto the dirt. You look up as the gate across the arena shudders open, the tiger from before comes parading out. You move as far as you can, backed up against a wall.
The beast saunters over to you. He leans down, breathing heavily in your face. "Make sure to struggle." He growls and pushes you to the ground with his heavy tongue. The tongue is large enough to smother you against the dirt. You squirm under the wet pressure. The tiger pulls the rough tongue into his mouth.
You take this chance to run, you dash across the dirt. Before you can reach the other side the feline pounces on you. He licks you again, this time with a soggier tongue. He slips his maw over your head, enveloping you in thick saliva. His breath smells of his past meals, acidic and rotting. He shoves you down his throat. You are pulled inside the beast. He purrs as you thrash in his throat. Your movement causes the crowd to cheer. You are pulled deeper into the tiger. The heat gets stronger as you enter the stomach. It gurgles in triumph as you enter the smelly chamber. A large belch is rumbles around you and the stomach contracts as some air is released. After sometime, you hear the tiger's voice.
"Listen, you can still help me escape, we are in my cell." He burps. The stomach contracts again. "If I let you out, you are going to help me escape, otherwise, I'm going to digest you. You have to choose fast," he burps again, the stomach squeezes tightly around you, releasing acids onto your body. "Because I can't stop natural processes."
