An alternate version of a commission for Dr.Whooves Dr.Whooves, with the internal view arranged to place a lot of sound effects around the poor tasty fox.

In the dark, damp confines of the alligator's stomach, Tempus' senses are overwhelmed by a wave of sensations. His fur, moments ago being dragged backwards by the slick flesh of her throat, is now pressed against the wrinkled, undulating walls of the alligator's belly, the sound of his own heartbeat mingling with the rhythmic gurgles and squelches of the tight stomach in his ears. The sounds of the alligator's insides are a constant presence- deep, resonant growls, the sloshing and squelching of digestive fluids, and the occasional muffled gurgle or groan from her intestines deeper down.
Her own heartbeat thrums in his ears, perhaps half or less the speed of his, and it occurs to the fox how much slower her metabolism must be. How often does she eat? How long does she sleep? He contemplates the alligator's intentions, a thought that stirs a complex mixture of awe, excitement, and fear. As his nose wrinkled, forced to breath the arid smell of her stomach, he reminded just what the organs purpose was. The reality of his surroundings becomes more clear with each passing moment, the euphoric distraction of the things her tongue was doing to him not a minute before already fading from his mind. She had felt so accommodating as she worked him down, but now that he's in here, with her gullet sealed tight above him, her gut has no need for such pleasantries.
The stomach holding him is not merely a passive container, but coming alive with motion at his sudden presence. As the alligator moves, the stomach walls ripple and contract, the fox's form being pressed and kneaded between the undulating muscles. There's a constant, rhythmic squeezing that alternates between gentle and firm, clenching around his curled-up body. The sensation is oddly intimate, the way it shifts him about slightly. The squelching sounds of the stomach's slippery digestive juices mix with the echoes of her breathing and movements. Each squeeze is followed by momentary release, a brief respite where Tempus can push his legs out against the confines of her flesh before being squished back into the fetal position. Her stomach works on him, feeling and sounding almost impatient as it groans and gluts around him, each squirm only making her walls undulate again.
The alligator finds a strange satisfaction in the way her belly moves in response to her slow digestion. Each bulge and push is a testament to the fox's stamina, and the fact the squirms slowly decrease in vigour proof of her accommodating, yet resilient, body. She relishes the feeling, almost letting him push and stretch her stomach just for the satisfaction of how effortlessly a simple clench handles his half-indulgent struggles and compresses him back into a wiggly ball.
His body exhausted, the strength drained out of his muscles from the sauna-esque warmth, Tempus finally stops testing the restriction of the alligator's gut and simply relaxes. His own excitement still stands proud against his belly, the sensation of the slick flesh of her gut around him keeping him engaged and enthralled, even as he comes to terms with what's happened to him. Her stomach, too, seems to have relaxed, no longer clenching but simply wrapping tight around him. He thinks about how much it feels like her whole body is squeezing in, trying to blur the line between his flesh and hers. He wonders if the gator outside pictures him in her gut, or only sees him as her own full belly already.
He can't see the smile on her face as she lies with her eyes closed, basking in the afternoon light filtering through the canopy, grateful that he's settled in at last so she can get to her napping and enjoy the feeling of the sun warming her bloated middle. Getting herself comfortable for a long wait...
