"Jeez, what's with all the yelling this morning sis?"
Linda recognized the voice as 'his' younger brother, Brandon. He also recognized the unauthorized sound of his bedroom door opening. "Brandon!? What the hell, nya!?" Linda exclaimed as his little brother walked in without a second thought. He would also like to sneak into his room, but not when he's still inside! Linda mentally slapped himself, still not used to referring to her current self as a male.
Brandon stepped inside, dressed in the same high school uniform. He attended the same school as Linda did, though he was just a year younger than 'him'.
"What are you talking about? We've never had a problem with sharing our space, sis!" Brandon replied, his nose twitching a bit.
"Well I... wait... did you call me sis? You still know I'm a girl, nya?" Linda said with some hope sparking in his eyes like a bishonen character.
"Wha-? What the heck's a girl? You've always been a boy, sis. Man, did you fall out of bed and hit your head, nya?" he said jokingly.
"No...!?" Linda was about to retort his brother when it hit him like a lightning bolt. 'Did... did he just say 'nya', nya?' he thought before looking back at him, only for his face to immediately switch into a state of anime shock.
Brandon's nose was becoming pointed and petit like Linda's while whiskers began poking out from his upper lip. His were already moving and poking through his hair while a ripping noise behind him was followed by the presence of a furry tail waving behind him. He blinked a few times in confusion at his sister's expression of disbelief, each one revealing increasingly anime eyes in the process.
What was even more shocking to him was that his brother was shrinking in front of him before his very eyes! His clothes began falling off him into nonexistence while his hair began lengthening in size, splitting into two twintails held by double cherry shaped clips before shifting from red to a soft pink tone.
His undershirt and briefs were all that remained before they began to change as well, merging together and changing from threaded material to nylon. When it stopped with his body, Brandon was now the size of an elementary student wearing a one-piece school-issue Japanese sukumiku, complete with a name plate on his chest with his name written in simple Japanese. It was also clear that it was suit for females as evident by the bulge of his crotch sticking out, causing Linda to blush out of embarrassment.
"Brandon! Didn't you notice you just changed into a cat, nya!? You look like a girl in elementary, nya!" Linda said in shock and a bit of frustration at his obliviousness to the situation.
Brandon simply tilted his head as a question mark seemed to manifest above his head before fading away from him. "Why is that strange, nya? I've always been a catboi, nya! And why do you keep saying that weird word, 'girl'? You really must have hit your head this morning, nya" he says walking out of the room, his arms oddly kept a distance from his hip before a small yellow inner tube filled the space, just below his pink furred tail.
Linda could only look with white circle eyes of surprise and a few stray hairs curling out of his head due to the stress of the situation before him. The first thing popping into his mind being, 'My little bro does look cute, nya...', after which was immediately followed with comical slaps to his own face. 'Nya! This is your brother you're thinking about! Incest is not cool, nya! Wait... if I have a dick, does that mean it's gay incest...~? Nya, NO! That's so gross!'
His self argument was broken by the sound of...
