There Michel sat, another catboi of a bulkier breed. His body was significantly more muscular than Linden remembered as Linda, and a bit taller. His hair was a softer shade of red than Linden's and styled to be a bit shorter and spikier. Beyond that, he had similar cat ears poking through, a cat-like face, paw pads on his hands and feet, and a slinky tail pointing up behind him.
Michel wore an open gakuran-style jacket, exposing a light dusting of chest hair across pecs forming a treasure trail down the abs. Looking lower, Linden saw Michel was in underwear briefs as usual. The subtly-ribbed large erection sticking out indicated excitement for seeing his boyfriend, or any boy for that matter. Lower down, he had skipped shoes and socks, rubbing and fidgeting together feet in pleasure.
All the while, a voice in Linden's head was yelling out in anger, terror, and confusion at the situation. To Linden, it was just a strange memory of a different-looking heavier-clothed Michel, like an artstyle of dirty detail and the uncommon great ape species 'human'. The changes felt humiliating and inappropriate, yet simultaneously not changes at all.
But going barely heard, Linda could only watch as Michel got up to sit on Linden's lap, despite there being enough space for the two of them. "Nya~ Morning sweetie~" Linden lead on in a mixture of casual and seductive tones.
"Mewl~ Morning darling~", Michel answered back in a drawling bass voice as he sat down.
Linden ground against Michel's ass, with the two rubbing and curling their legs together. The two loved trying out various positions and bigger body mass or not this felt like a good time for Michel to bottom. Something felt unfamiliar about Linden being the top today and the act of doing it right on the bus, but no comment came of it and the feeling passed quickly with a few rubs of Michel's tail over Linden's chest.
The bus began to shift as well, becoming open and more like a mobile lounge. Lots of couches, plenty of room to stand by poles, and showing off the various species of students inside like a mobile showroom. There were some free snack meal replacements by the back seats, so Linden popped open a bag of cat treats to substitute for breakfast while banging. The ride changed passerby caught in the bus' fumes due to the indirect contact with the catbois. It was a panoply of variant species and sexual mostly-masculinity animating more and more clearly over the world, redesigns step by step with only a few flexes and readjustments of where exactly being stepped to commemorate it. Even from the relatively cramped position of Linden busy plugging up Michel, Linda saw outside rhino-men, bears, a few cats and dogs that became catbois or dogbois and occasionally even humans. All the while she panicked as she witnessed more changes on the way to school, some happening in the distance implying it wasn't just her. Was this happening to everything?
Linden managed to cum first to fill Michel's hole. He spent more time jerking off Michel's cock to the unusual experience of it having soft bumps rather than true cat barbs. Neither bothered aiming, so Michel's spunk shot freely. It landed across a couch arm and a pantsless wolfboi student in closed gakuren that Linden didn't remember offhand. The now-aroused wolfboi licked himself and Michel clean, but was still jerking his own red rocket off by the time they made it to the next stop. Nobody really cared about the saliva, sweat, or semen on the chairs, besides occasionally licking it up or rubbing it in. Apparently almost all clothing and fur was designed to purge stains and inclement damage with just a little shaking and intent to be clean, so mess rapidly went away unless the buildup was wanted to stick. Michel apparently kept his ass creampied with catboi spunk on purpose and leaked into his briefs when he wasn't showing off.
School impends.
