'Welp'
'I'm out of there, I guess,' you had thought to yourself as you settled yourself in the back of a police car. You had just been released from prison after serving a one year sentence. You didn't want to think about your stupid choices. All you cared about was that you were out of that shithole of a place. You had no idea where you were headed now. The cop just told you that there was something that he needed to pick up from some shady-sounding place.
"There's a surprise for you here," the cop had told you as he pulled into the parking lot of some old-looking building. The thing looked abandoned, pretty nasty on the outside. 'I wonder if the "surprise" is some mystery disease...'
Well, it didn't seem like you were exactly too far off.
After what felt like half an hour of waiting, the cop and some two other guys came out of the building, wheeling out some giant cage that had a cloth over it, covering whatever could possibly be inside. They connected the cage to the back of the police car before the two men left, seemingly thanking the cop as he got back into the car. As soon as he got in, he would proceed to toss a key over his shoulder at you before starting the car. You caught the key, looking down at it skeptically. "The fuck is this for? The cage? What in it?" you questioned.
"Watch your tone, you'll find out when you get home. What's your address?" the cop replied, immediately steering away from the question. You sighed, rolling your eyes before giving him your address. Well, at least you get to go home instead of crashing at some random apartment. It took about another 30 minutes before you arrived at your house. You decided you would put the cage in your garage since it probably would fit anywhere else. The officer would help you wheel it inside before he turned to you, crossing his arms. "As a reward for taking this, here is your reward."
The officer would proceed you a huge wad of nothing but $100 bills before going back to his car and driving off. Now you were alone in your garage with some giant cage. You had no job, your car was gone, all the food in your fridge was probably rotten, and you had a big wad of cash. Great. You look over at the giant cage, wondering what the actual hell you were given. You didn't sign up for some pet giraffe or some crazy shit like that. You decided to just rip the bandaid off and find out what you were dealing with, grabbing the large cloth covering the cage before pulling it off with all the force you could muster.
What you saw was definitely not what you were expecting.
"HOLY SHIT-" you shouted, stumbling back a bit as soon as your eyes laid upon what was sitting in the cage. The fuck even was that thing? It was absolutely massive, explaining why the cage was so huge, having a long tail and scaly skin. The thing looked like some sort of fucked up mermaid, clearly being some kind of aquatic creature. It had messy, black hair and fins coming out of the sides of its head, as well as an angler lure coming out of the top of its head. It also appeared to have three arms, two on its left and one on its right. It wore a brown jacket with a white shirt underneath, as well as a black scarf around its neck.
You had never seen anything like that in your entire life. Maybe you should've paid attention to those boring animal video essays the teachers used to show at school.
The thing in the cage was curled up, its tail coiled around itself, seemingly to keep it warm. Was the thing even alive? Well, you could see the subtle rise and fall of the things body, which meant that it was breathing. Maybe it was sleeping, but if that was the case, how can this thing breathe out of water? How did it not hear you? You just stood there, staring at the thing for a moment before slowly walking over to the door to go to the kitchen. You didn't want to deal with whatever that thing was right now.
However, as soon as you grabbed the doorknob, you could hear something shifting behind you. You pause before slowly turning around to see that the creature was now sitting up a little, looking around cautiously. And then its eyes, which were completely blue, landed on you. It let out a low growl, backing up a bit before its back hit the bars of the cage. You didn't know how to react, so you just stood there for a moment before walking back over to the cage.
"I think you're probably the weirdest thing I've ever seen in my entire fuckin' life," you said, not really thinking much about what you said..until it actually responded.
"Excuse me?" the creature asked in response, not exactly too pleased by your words. You were startled by how it could actually understand you and talk back. Then again..the thing probably had the hottest voice you've ever heard. You were guessing it was a male just because of how its voice sounded.
"Oh- my bad, man, I didn't know you could-"
"Whatever, I get it," he said, cutting your apology off. "Say, you think you can let me out of here? It's super uncomfortable."
"What makes you think I can trust you, fish guy? You look like you could eat me whole!" you replied. It was a little difficult to trust something that was three times your size and had a bunch of sharp teeth that could shred your tiny ass to bits.
"Hey, I may be hungry, but that doesn't mean I'll resort to cannibalism. Besides, I don't have a reason to attack you. You're clearly not a threat in any way, shape, or form," he said, crossing his arms. Cannibalism? Was he implying that he was a human? But if he was, how the hell did he end up like that? You paused, giving him a skeptical look before sighing.
"Fine, you can get out. You better not break any of my shit, though," you would say before taking the lock on the cage and shoving the key into the hole, unlocking it and opening the cage.
You stepped back as the large creature slithered out of the cage, shifting a bit awkwardly as he tried to get his tail all the way out of the cage. Seeing him from the side made it a lot more apparent of how starved he looked, looking like he hadn't been fed in weeks.
"Geez dude, when was the last time you ate something? You look starved," you asked, raising an eyebrow at him and crossing your arms. Hearing your words, he glanced down at himself before letting out a huff and looking away.
"Those fuckers may have known how to cut me open and put me back together, but they sure as hell didn't know how to feed me. Bastards.." he said, sitting there for a moment before you spoke up once again.
"I was gonna order some food right now. Want some?" you asked. You already knew he would probably say yes, but you decided that you'd might as well make sure. As expected, he simply gave a nod of approval, prompting you to go fetch a device to order some food. You headed out of the garage and through your house to go to your room, and to your luck, it seemed like all your belongings were still there aside from your car. You took your tablet from your room and got on DoorDash to order some McDonald's since it was cheap and tasted good. However, as you were ordering the food, you remember how big that guy was. One bag wasn't going to be enough..you were going to need a lot more than that.
You made your grand order (that you were somehow able to afford with a bunch of money still remaining) and went back to the garage to accompany your new 'friend.' The two of you somehow managed to have a somewhat normal conversation, and you learned that his name was Sebastian. Hot name for a guy with a hot-sounding voice, you supposed. The two of you would chat until, eventually, the food finally arrived. You went to the front door when you heard the doorbell ring, opening the door only to find the delivery man standing on the porch with so many big bags of McDonald's that it was almost impossible to count them all at that moment.
You paid the man the appropriate amount of money, watching the guy walk away before gathering the bags, somehow managing to carry them all as you closed the door and went back to the garage. As soon as Sebastian saw how many bags you brought back, his eyes widened slightly, his stomach audibly growling, likely from the smell of the food and how hungry he was. It wasn't long before the two of you started feasted. While you simply kept a single bag to yourself, you let the big guy have the rest since he was absolutely starving. You watched him consume burger after burger and coke after coke while you were casually eating your food, seeing how wrappers, empty boxes, and empty cups were beginning to get littered on the floor.
After not too long, his pace began to slow down a little, wanting to savor his meal a bit despite the fact that it was all junk food. You had ordered lots of burgers, chicken nuggets, fries, and cokes for him to eat, having ordered them in the largest sized possible to make sure he was full by the time everything was gone. He continued to eat for a while, but then stopped once he was about three fourths of the way through.
"Man, I haven't had a meal like that in ages," Sebastian would say as he pat his stomach, seeming satisfied with everything he ate.
"Wait- you're full? Already?" you asked, seemingly unable to believe that he was full before he managed to finish everything, considering his size.
"Well, yeah, obviously. You thought I was going to eat all of this?" Sebastian replied, tilting his head slightly as he looked over at you.
"C'mon, man! I didn't order all this just for you to not eat it all! Can you try to eat the rest?" you said in a somewhat pleading tone. Sebastian would sigh, looking at the remaining bags before glancing away.
"I suppose I can try," Sebastian replied before resuming his eating. He would try to just eat it all as quickly as he could just to get it out of the way, but his stomach wasn't exactly too pleased about this. He let out small grunts as he stuffed himself, feeling his already full stomach straining a little while trying to fit everything inside. By the time he managed to finish completely, his stomach had bloated quite a bit, giving it a more rounded appearance as it let out small rumbles of protest. Sebastian would let out a long groan, holding his stomach before slowly lowering himself onto the floor, curling up a little as he tried to ignore the discomfort.
You paused, staring at him for a moment. Seeing him like this..it made you feel some kind of way. You slowly went over to him before gently placing your hand on Sebastian's stuffed belly, prompting him to let out another small groan.
"Don't..ngh..don't touch me.." Sebastian growled, glaring at you, but he did nothing to actually stop you from touching his stomach. You would gently run both of your hands over Sebastian's stomach, feeling how it was somewhat firm from how much was packed inside him. Despite his protests, Sebastian seemed to relax a little from your touch, closing his eyes and letting out a small sigh.
"There, there, Seb. Just get some rest for now," you would say to him as you gently rubbed his belly, watching as he seemed to slowly fall asleep. Once you were sure that he was asleep, you grabbed the cloth that was originally covering the cage he came in before carefully placing it over his body, using it as a sort of blanket for him. You would watch him for a moment, smiling softly before eventually walking out of the garage and going to your room.
