The ever-changing Perths were still driving along the road, not caring that anyone might see them as they were slowly reverting to their old equine forms. In fact, Cathy didn’t care if anyone saw her without any clothing on. What they did care about were each other, and changing any humans they encountered along the way.
Case in point, Jacob only had the one increasingly hoof-like hand on the wheel, the other wrapped around Cathy as her tail reformed fully, swishing it slightly now her hair becoming a dark brown mane that matched the long hairs of her tail. And when he wasn’t looking ahead to see the dirt road turnoff, he had his focus on her. Her chest was beginning to expand outwards, her human breasts seemingly being absorbed by it while her feet were now her proper horse hooves.
They would have remained like that, had it not been for what lay ahead. Even with his muzzle beginning to enter his field of vision, he could clearly see a pair of humans some distance ahead, wearing large backpacks and thumbing for a pick up.
“Those two next?” Jacob suggested.
“By all means.” Cathy encouraged him.
“Then I wish that the two humans I see ahead of us will now become horses.”
As they approached them, they were able to see them stumbling around as their balance started to give out with their bodies becoming top-heavy. Hooves tearing through their boots as their heads pushed out into muzzles, while their arms grew to serve as front legs as manes and tails developed. Their clothes shredded and falling onto the ground by the roadside. Their transformations complete as the Perths drove by laughing.
“Did you see their faces?” Cathy laughed out, unable to hide her glee at their actions.
“I, I, I sure did!” Jacob joined his wife in the pleasure they derived from it. Not even distracted by the sound of his own longer feet finally overpowering the boots he wore, the black hooves dancing around for a moment before its purchase on the Gas Pedal was restored.
So caught up in their laughter they were, Jacob’s grip on his overloaded bladder gave out. The front of his denim overalls turning dark as the waste poured out of his growing horse cock, the wetness pulled down to between his widening legs. Until his own torso tore the straps holding the overalls up to allow the front of it to flop down, his mottled pink and black cock dropping forwards to continue its task of relieving Jacob. An act that fazed neither himself nor Cathy in the slightest, since having been horses to begin with, they saw no ill of it.
“Finally losing the clothes then?” Cathy teased him between receding giggles as she kept her arms wrapped around Jacob, the hands fully-formed hooves now. Looking down to see the hefty shaft with its equally weighty balls just barely visible.
“They were going to fail, and it did feel good when the straps succumbed.” Jacob admitted his enjoyment of it. “The rest won’t be far behind.” He wasn’t kidding, the seams holding the legs of the overalls, along with his sweater together were now feeling the strain, and he knew they couldn’t last more than a few minutes now.
“So Dear, what exactly do you want to do when we get there? To the Cabin?”
“I, haven’t thought about that.” Cathy confessed. “But let’s worry about that when we get there.”
“Agreed. And here’s the turnoff now.” Despite his own hoofed hands that made maintaining his grip an effort, Jacob succeeded in turning the truck onto the dirt path that would lead them to the Cabin.
“I wonder how that “daughter” of ours is doing.” Cathy asked slyly as she shuffled her widened ass over to get a look at the still-on monitor.
