He couldn't have been more wrong!

Suddenly, like a shot out of a rocket said forming "normal dog" pool toy shape became bipedal as she shot up to match his height. Her "collar bone" reshaping to match a more human based structure, her paws become half human hand like and half paw like, meanwhile her previous "barrel" of a dog torso seemed to find the air in it pushed outward from two invisible hands. Said hands would continue downward forming jutting anthro hips and reaching around to grab the tail and make it proportionate and befitting of a anthro husky dog woman. Her paws that she stood on in her bipedal form would stay largely the same except growing bigger just like Derek's were as to provide a sort of "maximum balance" and stability alongside the tail, whilst her legs reshaped to gain obvious round calves and thick thighs. Her more sexually appealing features seemed to all be created identically to Derek's own, her chest growing a plump duo of juicy chest melons that were just like generic balloons shape and size also just like Derek's with an ass matching in size completing the hourglass figure.

The black coloration of her "fur" seemed to in its design to be as if a dark blanket had been draped over her body as it flowed down either side from her temple giving a sorta angular look and the black almost perfectly framed her face as it went around just belong the chin around the top of the neck leaving her face almost perfectly a pristine snow white. Her snout reshaping into a shortened muzzle as her eyes became eyes she could use and her muzzle became moveable she seemed to make a yawning motion, and despite the deep piercing icey blue of her eyes a clear warmth was visibly within them as they locked onto her lover as he finished the final few pumps. Her ears being one of the biggest differences from her lover besides their colors as they pointed straight up even in their plastic composition, finishing off her new form as her tail wagged and she looked over herself in amazement. Groping a breast and a ass cheek, her whole body filled with warm air with a sort of pressure to it to make her body feel all the more real, a perfect companion to her dearest doggy Derek, and as if to reflect this she proceeded to give her beloved doggy "kisses".
