Jenny positioned herself so that she was facing Kris, yet still able to use her laptop. One hand gripped Kris's head, then pushed it between her thighs so that the vixen's mouth and nose were right up against her red tights-covered vulva. "Worship my pussy with your face," she commanded, almost boredly, and immediately Kris started to nuzzle and lick against the nylon, both of her hands coming up to steady herself by holding Jenny's thighs. Jenny squirmed slightly, breathing out a small sigh of pleasure at the sensation as she worked quickly on the laptop.
Instantly, the two were naked, and the costume had disappeared. They looked at eachother, blinking in confusion. The one on the left turned and bent over, struggling to stop herself like Kris had, though she was much more vocal about it.
"Wh-what's happening? Why can't-why can't I stop moving like-I can't move!" She exclaimed, both of her hands pinning theirselves to her sides while spreading her ass cheeks wide open.
"Oh-Oh god. Oh god no, I-I-I don't want to-" the coed on the right stammered as she, too, bent over and shoved her face into the first girl's ass. Her muffled pleas could be heard as she started to greedily and eagerly lap the first girl's asshole, shoving her tongue into it while her lips sealed themselves to the dusky pink ring, her cheeks squeezed between the first girl's cheek.

Their flesh began to knit together, the front girl's arms melding into her sides as her upper body shrank and her head elongated into a horse-like shape.
Chestnut brown horsehair began to fill in their flesh as the head girl's pleas turned to whinnies and whickers, both of their feet slowly shifting into equine hooves, the rear girl's breasts migrating down her body to just above her waist. The changes progressed further and further, muscle filling out and becoming more supple as the two became one, like Jenny had done years back (and a few other times in between).
Eventually, all that was left was a dark brown thoroughbred mare, and with another instant snap of her fingers, Jenny had fitted the horse with bit, bridle, blinders, and saddle.
Jenny looked around, debating on whether to move on, or continue her fun in the clothing store. She continued to comb her fingers through Kris's hair, holding her face against what had been Amber's face, and through there, her now-soaked labia. Jenny snapped the gate to the mall back open, then...
