The moment Janet and Daniel took their first steps outside, with a warm breeze blowing on their bodies and cold concrete under their bare feet, they had a peculiar feeling. The suburban town in front of them, that they both took for granted the last 30 years, now looked completely different to their enlightened eyes. The other adults were all gathered in the parking lot, admiring each other's nude bodies fondly. Many had already left to explore their home in a new way. Right now, it was only a small group of ten or 20 people, but that number would grow and grow. Society would break down at a rapid pace, and this sleepy town would become a concrete jungle where the only law is nature! But that's still far into the future.
For now, Daniel and Janet were so distracted by their new freedom that they weren't thinking about sex at the moment. Now that they had the treatment, they could have it anywhere, at any time, and be as dirty as they want! The very idea tickled Daniel all the way down to his twitching cock. But the tickle wasn't just mental... a few inches up, his pubic hair was slowly growing and spreading across his thighs. Janet's hands and feet were ticklish too, and in a second, fair brown fur grew from her skin and spread quickly up her arms and legs. How surprised they were when they glanced at each other and saw the conspicuous changes!
"Have you always been this... hairy?" asked Janet.
"You're hairy too. Even more body hair than me!"
Janet laughed openly. "I've always hated shaving! Now I don't have to!"
"Heh, you'd look fairly sexy with a hairy back!"
Janet twirled around. Just as Daniel said, she already had visible hair on her back! And besides that, her posture was unusually stooped over, with her hairy knuckles reaching the ground. Daniel took the same posture a few seconds later, finding it more comfortable than standing straight ever felt. It took Oliver several months of exposure to devolve to that point, but in a few short minutes, his parents were already there. But the wave of transformation slowed to a stop, building up energy in preparation for the next wave. The two looked Neanderthal but still human.
Since the transformation was more rapid than Oliver's, the couple suspected it might be only a few days until they turned ape completely. It was exciting to think about, but Janet wanted to speak to Oliver about it as soon as possible. That is because they all might lose the ability to speak and understand language before they knew it! She turned to Daniel and asked, "Why don't we show Oliver our new selves?" Daniel replied, "Oliver... he love this." His dick was starting to firm up again. "Want sex too."
