This wasn't what Jason had planned at all. His childhood dream was to become a cute little furry companion for someone. Bring happiness to everybody by simply living his whimsical pint-sized life. He'd have lifelong fantasies about living in a small dollhouse, sleeping in a matchbox-sized bed in his tiny pajamas. Even brushing his teeth in the morning would be an adorable thing for everyone to see. He'd bring joy to others and that would be enough to satisfy him. He was completely sure he wanted a life like that. To be a cute animal character that made everyone smile, just like in movies.
When he had gone to the transformation center, that's what he expected his life to become, but...
"There you have it, you dumb shit." Stan finished replenishing the water bottle half-empty with tap water and placed it back on the cold bars that conformed the walls of the rodent-sized prison. "I know you prefer to drink Cola, but those days are long gone. This will be your only drink from now on. Make sure it lasts the whole weekend, I ain't refilling this damn thing every single fucking day."
The naked animal inside the cage was still sitting down with its bare butt touching the cage's floor, its white furry back turned away from Stan. The minuscule human-mouse hybrid was still pissed at its brother, and wouldn't look at him in the face.
"Eh, did you hear me, Cheesers?"
Jason's rodent heart skipped a beat whenever he used that silly-sounding name. It felt so degrading every single time.
"Cheesers? Answer me you stupid mouse." Stan asked again, very aware he was provoking the mouse.
Jason squeaked sarcastically. "(You denied my voice away, how do you expect me to respond, bastard.)" He thought, and showed Stan his middle finger as a "fuck you" in case his high-pitched squeaking hadn't sound sarcastic enough.
"Glad to hear no complaints at all. Do you need anything else, bratty rodent?" Stan asked with his very own helping of sarcasm.
The mouse sighed. He looked down at his naked body. "(Clothes.)" He thought as he shivered from the cold. But there was no way for him to articulate any comprehensible words.
"I still can't believe you willingly turned yourself into a pest. It won't be long until your tank starts smelling like a sewer. But this way I can keep you safe from yourself and your moronic mistakes. And I get the whole house to myself, too" Stan grinned. "Remember, you wanted this. No going back now."
Now, that did it!
Jason stood up, turned to face Stan, looked at him defiantly in the eyes, he squeaked angrily, ("THIS IS NOT WHAT I WANTED!") pointing an accusing finger at his giant captor and then-
...And then Jason remembered he was naked. His pink cock and low-hanging balls in full display for his brother's amusement. The whiskers on his face and the little mouse ears slowly flopped down at the same time after his body had become frozen mid-squeak.
Stan bursted out laughing. "Hahahaha! I hope it's the transformation serum because damn, your pecker looks embarrassing!" The naked anthropomorphic rodent rapidly covered his shame with his pink hands, making him look even more ridiculous to his brother. Jason, face blushing, turned around with embarrassment but that only caused more snarky remarks to come at him.
"Nice pearly white ass, Cheesers!"
Jason didn't dare squeak anything else, he simply tried to hide his buttcrack by placing his flaccid rodent tail over it with one of his hands.
"What an overtly modest little fella! As if pets had any modesty, hahaha." Stan mocked.
It may seem like he was being mean to his brother, but Stan actually thought that he was being too talkative with the pet and that Jason should be grateful he had the privilege of being spoken to like he could understand human language at all, as Stan wasn't the kind of person who talked to his pets. Or even liked pets at all.
"I'll be right back. Oh, and try not to jerk off too loudly while I'm gone, Cheesers, because I'm sure this is all a perverted sexual fantasy of yours, you sicko."
Jason felt offended. Becoming a small mouse was his lifelong dream, not a simple perversion! Why couldn't his brother understand that?!
Stan left. Jason had no way to know where his captor was headed, as his current living space had been reduced to the small cage.
Imprisoned with not a shred of clothing or dignity. How pitiful! The little nude mouse man looked at the hamster wheel and stuck out his tongue in disgust. "(I should live in a miniature house with all the modern life commodities. It would even be cheaper than building a full sized house. I shouldn't be a freaking pet!)" He thought. Remaining naked in such a small tank for long periods of time would drive him crazy. Not to mention the fear of Stan coming back any moment to torment him more. Even inmates in prison must receive more humane treatment than this!
It was Friday and Stan didn't have to go to work until next week. This meant that Stan had plenty of time to be with his pet brother if he wanted... Or, wait, what if Stan goes away for an escapade for the weekend like he usually does? Would Jason have to wait three whole days trapped in that cage until Stan came back? Would Stan bring him along for the trip? ...Would the latter option be even worse? Could Jason expect to survive in the world outside his little cage?
The naked little mouse-man was going crazy thinking about every possible disgrace that could happen to him, and he had been in the hamster tank for a meager ten minutes! Shit, maybe he really was dumb for having transformed himself into an eight inch tall mouse!
Eventually Stan came back to his naked pet brother, and he looked like he had an unwelcome surprise to share.
