———————————————————————————
Another miserable run down in the Hadal Blacksite.
You had no idea how many times you had died down there and had the pain of coming back just to try again. And all this for what? Some stupid crystal? Freedom? In all honestly, you started to think that dying might be the better option. Oh well, you signed up for this. Should've said no to that sketchy offer to get outta jail.
After somehow managing to get out of an encounter with stupid fucking Pandemonium that you hate, you felt a great sense of relief wash over you when you entered the next room and saw a vent grate fly across the room.
"Hey..over here," you heard an all too familiar voice call to you from the other side of the vent. You sighed before getting down on your elbows and knees and crawling through the vent, pulling yourself back onto your feet once you were out only to see the large fish man sitting there, gazing down at you with a calm expression. "Got some items in stock that I'm sure will be worth the price."
"Thanks.." you muttered as you approached Sebastian, looking over the items that were currently displayed on his tail. Gummy light..hand crank flashlight..medkit..flash beacon..and a flashlight. Your eyes would linger on the flash beacon for a moment, the gears in your brain turning. 'I mean..I have been having a pretty bad day..why not have a little fun.'
You picked the flash beacon off Sebastian's tail and handed him $200 worth of data, prompting him to thank you as his fins fluttered a little. You would also buy a few batteries and take the keycard off the farther desk before heading over to the vent you came from. However, right before it seemed like you were going to leave, you decided to be a little menace. You pointed the flash beacon at Sebastian before flashing it at him, making him let out a sharp grunt and cover his eyes.
"Why you little-!" Sebastian snarled through his teeth before snatching you up off the ground in one hand and holding you up above him, glaring at you. "I'll make sure you don't do that again.." he growled, ripping the flash beacon away from you with one of his free hands before doing something rather..unexpected.
Without any kind of hesitation, Sebastian proceeded to shove your head into his mouth, startling you by doing so. Seemed like he wasn't exactly in the best mood either. You had no idea what to do as he stuffed your body into his mouth and down his throat, feeling yourself struggling to breathe slightly as you went down, his teeth lightly sinking into you through your gear a little.

— ENDING 1 - SAFE —

When you finally reached his stomach, you took a moment to catch your breath before trying to look around a little, only to see nothing but darkness. You paused, processing the fact that Sebastian literally just fucking ate you before squirming a bit, trying to get into a more comfortable position. You could feel the warm, wet surface of the inside of his stomach pressing against you as you tried to adjust until you felt something else press against you, which was likely his hand against his stomach from outside. You could feel him rubbing and patting his stomach as you listened to the various noises that his guts were making, the sounds ringing rather loudly in your ears.
To your surprise, you didn't feel any kind of acid trying to eat away at you. Maybe your gear just so happened to be acid proof, but you weren't exactly sure. Honestly, it was a little..comforting to be in Sebastian's stomach, as weird as it was. It sort of just..felt nice. Comfortable. You could get used to this..but you also kind of hoped that he would let you out somehow before you starved to death or something.

— ENDING 2 - FATAL —

When you finally reached his stomach, you were immediately plopped into what was likely a puddle of digestive acid. Everything was dark and you couldn't see a thing. You tried to gasp for breath for a moment, breathing in the warm, humid air that happened to be in Sebastian's stomach. You couldn't believe that he ate you just like that. You squirmed a little in an attempt to get comfortable, but you knew that wouldn't change anything. You were going to get digested eventually and there wasn't exactly anything you could really do about it. You heard the loud noises of Sebastian's guts ringing in your ears as you shifted around inside him until you felt something press against you, likely his hand rubbing his stomach.
You settled once you managed to get comfortable enough, letting out a sigh as you leaned back. You could already feel the acid eating away at your diving gear. It wouldn't be too long before it would break through and start tearing your skin apart. You decided to just close your eyes and go to sleep while you could, not wanting to feel anything while Sebastian's stomach slowly digested you. At least it was pretty comfortable all things considered. You slowly started to feel your consciousness slipping away from you, hoping that you would maybe be out of this situation once you eventually woke up and you would never have to talk about it with Sebastian. Ever.
