Matsuri, apprentice knight of Nightmare, was patrolling the streets of Landsol. There had been a string of robberies in this part of town, and the tiger girl was eager to prove herself in the eyes of her fellow knights by catching the thief.
Her eyes scanned her surroundings trying to spot anything unusual, but nothing seemed out of the ordinary: people out and enjoying the weather, children playing with a ball, an elf stalking who she recognized to be the Gourmet Guild, a middle aged woman selling fruit from a stall...wait what was that earlier?
Matsuri focused her eyes on the shifty looking elf. The stalker seemed to be a petite girl, but she was wearing the clothes of an adventurer and holding a spear-like weapon; she might put up a fight if Matsuri was going to try and take her in for questioning.
She seemed to be hiding from her target behind the corner of a building. Her suspicious behavior had Matsuri believe that she might be the robber from the reports, she had to take her in!
 So far the elven girl hadn't noticed Matsuri, and Matsuri wanted to keep it that way, she was going to need the element of surprise to catch this criminal. With the soft steps of a sneaking cat she silently made her way towards the distracted elf.
Matsuri was of the beastfolk race, who are known for their animal-like attributes. She herself had ears and and a tail that resembled a tiger, and she also inherited the hunting skills of the apex predator. While she was trying to hide her physical features to better fit in with the otherwise human knights of Nightmare, she made full use of those skills when fighting or tracking down criminals such as this.
As she slowly but steadily approached her future pra-... her future prisoner, she began to feel and more and more like fearsome hung-... hunting predator.
Just as she got close enough and getting to pounce, her mouth watering with saliva, her empty stomach growled.
Startled by the sound the elf turned around and found herself face to face with the apprentice knight.
"S-stop!" Matsuri yelled after regaining her composure, "In the name of Nightmare and the throne, you are under arrest!"
The petite elf simply shrieked in response and started running away, with the tiger knight following shortly after. Unsure where to go to in her panic, the elf was dashing down the street in a zig zag pattern, which reminded Matsuri of a rabbits attempt to get rid of a hunting predator.
The thought fueled Matsuri as she gave into her instincts chasing her prey. Her instincts helped her take control of the chase, since the elf was running away from her, Matsuri could steer her into a general direction, and she managed to direct the running girl dowm some alleys, away from any curious onlookers, and eventually into a dead end.
With no where left to go, the elf turned around just in time to see the hungry cat leap at her.
  ***
 "Huh, she must have passed out from the shock." Matsuri thought while looking at the unconscious elf.
An innocent person wouldn't have run, so surely she was right that this was the person responsible for all those robberies. And now that she caught her she could...she could bring her back to the garrison to...to put her into jail and... And why were her feet in her mouth?
Matsuri caught herself swallowing the girl's feet.
Huh?
This wasn't how catching criminals was supposed to go, right?
Matsuri tried clear her thoughts but at the same time kept swallowing down the calves of the elf.
She caught her pray, she it was only naturally for her to eat it, and with the divine flavor of these thighs, who could blame her?
When she reached her pray's hips, her stomach starting to bulge out, Matsuri made sure to press the girls hands into her mouth as well.
She was just doing what came naturally, following her knightly instincts, surely the other knights would do the same in her situation? Matsuri kept thinking as she swallowed the girl's waist.
This was the safest way to transport a criminal, yeah, they can't escape this way until they are taken back to jail and let out there.
As Matsuri swallowed her pray's small breasts she suddenly felt it twitching. Oh no! She was waking up again. In a hurry Matsuri swallowed dowm her shoulders while the elven girl was still regaining her composure.
"Huh, why can't I m-" she stopped and an expression of shock filled her face when she saw what was going.
Matsuri quickly used her hand to cover up her pray's mouth, so that it couldn't scream for help.
A soft muffled whimper came from the girl as her sensitive ears were pushed into the predator's mouth, and a final push after the rest of her despairing face vanished into the tiger girl, who finished her meal by slurping up the rest of her hair.
  ***
 Matsuri let herself fall on her butt and gave out a satisfied sigh. Enjoying the feeling of a full belly, she gave it a rub while listening to the muffled pleas.
Of course she didn't have time to take a nap to digest, she was gonna let this prisoner back out into a jail cell of course. Matsuri stood back up and started waddling back to the garrison. Her pray may have been petite, but Matsuri was far from being big herself, and her very large belly made walking difficult.
Going down some back alley shortcuts, which had the bonus of her not being seen in this state by anyone, she was confident she could make it back before digestion kicked in.
That was until a kick from inside her sent her tumbling.
Her pray apparently had realized screaming for help and pleading to be let out wasn't going to work, and so it took up trying to fight it's way out. Matsuri's stomach however, didn't intend to let it's meal go and fought back, as was evident of the gurgling noises it made.
Matsuri tried to calm down the elven girl inside her, telling her she was gonna let her go if she just calmed dowm long enough for her to get back to the garrison, but the girl inside her couldn't hear her. She also couldn't keep walking with this fight going on inside her, so she eventually just sat down leaning back against a wall, forced to wait for her pray to calm down.
  ***
 Matsuri wasn't sure how much time had passed, but eventually the struggles of her meal became weaker, her stomach letting off an aggressive victory gurgle.
Matsuri got back on her feet, the struggling of her pray had made her exhausted, but she still had to muster her strength and get back into a jail cell before it was too late.
Accompanied by the gurgling noises of her stomach hard at work, she hurriedly made her way back to the garrison. She only made it halfway though when she could feel her stomach tightening followed by a loud belch.
"Oh no" Matsuri thought as she prodded her belly. It had shrunken more than she had hoped to see and wherever she poked she felt more slush than girl inside of her. Another burp sent her pray's half digested underwear flying out of her mouth.
This wasn't how they were supposed to treat criminals, but they are still criminals, and if that elf didn't want this to happen she shouldn't have committed those robberies, Matsuri reassured herself.
Her stomach happily slushing and gurgling she finished her way back to the garrison to deliver her report.

 Back at the station, Matsuri ran into her captain, Jun.
"Ah, Matsuri." Jun said, "Just wanted to let you know, Tomo caught that thief responsible for the recent robberies. You don't need to be on the lookout for them anymore...Uhm, excuse me for saying this, but have you gained weight?"
"I'm sorry, Captain, but I have to use bathroom real quick!"
