coos, wrapping up four paws in squirrel cheeks Tell me all about your wants and needs and lusts and desires~ The mouse hikes herself up onto that waiting bat seat, happy to be surrounded by two of her dearest friends.

His blush is so warm shi can feel it through his thick fur. Looking into the eldermouse's eyes with sincere desire, not just for hir but for what shi represents. Echoen, conversely, cuddles from behind, a fair bit larger in height and scale, providing ample support for hir heavenly heavily endowed hermfriend.
"I want..." He stammers out, torn between saying it out loud and simply making it happen before he explains it. "I want the Victoriazation of the sinfully young, to have the idea of mouse and multi and more complete a corrupted corporate takeover of bodily autonomy, physical reality, mental alacrity, and social stigma." He gulps, chest heaving, lap bulging profusely. "I can get us started with a scenepose, but the shock value is a key part of it. Particularly amongst the parents, who know their offspring shouldn't be like this..."

Victoria gives her ample, if meager in comparison, glutes a shimmy to properly placate her posterior's preference in seating adjustment. The executive mouse pressing herself quite comfortably into her larger batty friend. "HEAT is always looking to branch out. Tap into markets that haven't been considered. A cereal for breakfast would get the largest targeted age range. Lots of meeses, and tits, and cocks, and balls shapes made of 4000% sugar to really go for that cub demographic."

Balros draws in a breath as he pulls out the H.E.A.T Illustrated magazine from his backpack. He'd already be in enough trouble for being the only boy to sneak into the girl's slumber party, but bribing the host girl with kisses and musk and enough of his licensed pheromones while at school got him the invite and the assurance of an unlocked back door. He knew everything he was doing was wrong, but the insurance provided to him by the local chapter of H.E.A.T's Youth Outreach program all but guaranteed that the authorities and parents would have enough on their plate to deal with than get on his case for what he was about to do.
Slipping the big-bold-lettered magazine over to the girls, the 3D-esque image of the corporate corruption mouse caught their eyes, attention, and a special permanent part of their young impressional brains. The sleeping bags were scattered all over the living room, and he positioned himself between the couch and a large cushioned chair, most out of view of any peeking parents that might spy the musky intruder. The host girl began to read the cover out loud for the others, nobody but him noticing the subtle second pair of arms slipping out from her sides. One of the younger girls, who was already a mouse by luck of birth, was absently stroking her belly as she listened and watched, shirt lifting as her womb and breasts grew slightly each time Victoria's name was said aloud.

There were no changes to notice, after all, as extra limbs sprouted where they always were or bellies starting to bloat with the latest generation of HEAT's future employees. Wombs filling with the pride of the Hightail line as tits grew, swelled and filled with the milk needed to carry untold numbers of young. One of the girls in the party was busy fondling one of their friends, stroking the growing mouse package that was utterly straining most of their sweatpants. The extra weights that had always been there were growing tender and the extra hands were certainly a fantastic help.
Of course, as the lab mouse-white fur started to spread across the girls, none of them really noticed that even as their breasts, bellies, and sacks swelled, the party-goers all were starting to shrink, and shrrink more so than any Victoria would. But they weren't shrink were they? The girls were always that young, right?
