Derrick shook his head and tried to clear his mind, realizing what was happening and feeling a mix of confusion and arousal. He knew that they were both still human inside, but their bodies had already transformed into horses and their instincts were taking over.
He couldn't resist the sight and scent of Vivian's marehood any longer, and he mounted her from behind. She neighed and whinnied as he entered her, the sensations overwhelming her equine senses. Despite the strange situation, the pleasure was too intense for either of them to resist.
Derrick eagerly mounted Vivian, his instincts taking over as he began to thrust into her. The sensations of his new equine body were overwhelming as he felt his cock slide easily into her wet, warm pussy. He nuzzled her neck and mane as he fucked her, the scent of her arousal driving him wild.
Vivian moaned and brayed as she felt Derrick's cock deep inside her. She arched her back and pushed back against him, urging him to go deeper. Her own instincts had taken over completely, and she was lost in the pleasure of being mounted by her mate.
As they mated, the attendant watched from a distance, a smile on her face. The transformation had gone perfectly, and the couple would make excellent additions to the zoo's collection of breeding animals.

As they mated, their human minds struggled to stay in control. They knew that they needed to find their missing son, but their animal instincts were too powerful to ignore. They continued to mate until they both reached orgasm, their equine bodies trembling with pleasure.
Afterwards, they lay together in the grass, panting and sweating from the exertion. The reality of their situation hit them again, and they knew that they needed to find their son. They stood up and began to search the enclosure once more, hoping to find any sign of him.
Vivian's mind was in a whirlwind of emotions as she lay beside Derrick, her body still tingling from their intense mating. The mix of pleasure, confusion, and guilt consumed her thoughts. She knew that they had lost track of their son, and here they were, giving in to their animal instincts in the midst of the search.
As she stood up, her equine body swayed a little, adjusting to the newfound weight and balance. She couldn't shake off the guilt and worry that gnawed at her. Vivian's human mind fought to regain control, to focus on finding Sam and getting out of this bizarre situation.
"Derrick, we need to find Sam," she said, her voice filled with determination, tinged with the remnants of arousal. "We can't let ourselves get lost in our animal instincts. We have to stay focused and find our son."
Derrick nodded, his equine eyes reflecting the same determination. They resumed their search, trotting through the enclosure, calling out Sam's name. Vivian's mind was conflicted. She couldn't shake off the lingering sensations from their mating, but her love for her son pushed her to prioritize finding him.
As they continued their search, their human minds struggled to stay in control, occasionally giving in to their equine instincts. But with each passing moment, the urgency to reunite with Sam grew stronger, overshadowing their animal desires.
