"I know. But I really do want to speak to Oliver one time before I can't anymore..." Janet's sentence was cut short, as she took a sharp inhalation of breath and moaned animalistically. Even though she wanted to see Oliver right away, Janet's pussy was experiencing some overpowering primal heat. Not like the normal human horniness she was used to, this was an almost hypnotizing force that left her unable to resist. She managed to answer with some effort, "Ugh... got plenty of time, have sex now!" Her thick, hairy fingers began to tickle the interior of her vagina, bringing her a wave of pleasure that was amplified by the mental changes of her transformation. From one look at Daniel's twitching penis, he felt the same thing. They couldn't resist each other now.
Janet backed up on the curb, stepping onto a patch of dirt and sparse grass, and dropped to the ground on her butt, spreading her legs wide and open. "Here... now!" she grunted. Daniel wasted no time on foreplay, as soon as his wife hit the dirt he was already getting down on his knees, climbing into a mating position. His member rammed into Janet's slit with no warning and immediately went to work. Janet's hairy backside rubbed against the cold dirt and grass as Daniel thrust into her over and over, cooling off some of her excess heat. No dirty talk was exchanged between the two lovers, but it wasn't needed, as they were acting on pure instict for the moment. Their surroundings faded into the background, just a distraction from the pleasure.
Speaking of their surroundings, more than one couple was getting together in this parking lot. It turns out that arousal is a common side effect of the serum. This historic hospital was becoming host to an orgy of rapidly transforming humans, ranging from reptiles to birds and mammals in various stages of transformation. Such a unique sight did not go unnoticed, there was a crowd of onlookers in the street watching the activity. Many citizens went outside nude just to get a head start on the future. At this point, the whole town knew that a change was coming sooner than they thought.

For the moment, Oliver did not know what was going on. He was walking home with his friends behind him, expecting to find his parents at home like always. There was the obvious difference that he was a wild ape child, but he noticed no change besides that. Marcus turned to strike up a conversation. "I hear they've developed a transformation for adults. You think it's ever going to come to this city?"
"I haven't heard anything about it."
"Hopefully it does eventually. If I become a full ape and my parents remain human, it'll be hard to relate to them."
"I'm sure it won't come to that. I'll ask my folks what they think of the idea."
While they were waling, the boys slowly noticed strange things going on. No traffic on the street at all, any cars they saw were stopped haphazardly in the street and abandoned. But there was a crowd of adults hanging around, with more than a few totally nude. Tim had to dodge some very little kids who streaked past him. The crowd was more dense when they got close to the city hospital, where some kind of commotion was happening in the parking lot. They eventually squeezed themselves through the crowd and saw... well, they were adolescents, but it was plainly obvious what they were looking at.
Oliver took a sudden interest in a mating pair of apes in a patch of dirt. With improved reflexes, he jumped the fence, landed on the hood of a car, and jumped down to get a closer look. The male and female were somewhat ape, but still had some familiar human features... they looked remarkably like his parents. The monkey child sniffed their scents. They smelled a lot dirtier than before but that was definitely his mom and dad having dirty animal sex! Janet turned her head and just happened to catch Oliver eye to eye... moments before Daniel hooted triumphantly and came an impressive load into her opening. Janet bucked her hips against him, taking in her husband's orgasm without a care.
"Wow......cool!" thinks Oliver.
