Oliver's mom and dad had their own appointment while this was happening. For the moment, they were in a packed waiting room at the same hospital where Oliver got his first treatment. The other patients in line were also parents of transformed kids, or siblings, or random folks around town who wanted to join the excitement. Oliver's parents were seated in the back and there were many numbers in front of them. When the door finally opened, a married couple walked out in the nude, looking as proud of themselves as they could be. "Next!" yelled the doctor.
While they were waiting, Oliver's mom tried to strike a conversation. "So, Daniel... you sure you want to do this? We won't be able to go back."
"I wouldn't want to, Janet. Besides, civilization won't last long after the rest of the country picks this up."
"The rest...?"
"The serum is so effective that we could make America a natural paradise again, just like the old days. All the big political parties are supporting it."
"I'm just glad they let us join Oliver in his new life. I wouldn't want to grow old without him."
It took over a half an hour to get through everyone who wanted the treatment. Each patient walked in a human and walked out nude, a future wild animal. Only one number left. "Next!"
When the couple entered the office, they met the smart-looking doctor and an unusually hairy nurse who was hunched over like a dog and had only a loose lab coat for clothing. "Ah, you're here for the monkey treatment?" asked the doctor. "There is a few things you should know first. This is a much more potent dose than your child's, so you'll go through the process very rapidly. Most likely, you'll be full ape well before Oliver is. And secondly..." he pulled down a map of their town, "Once most of the humans in town are transformed, we'll use a new sattelite to make the environment more suitable to your form. Anyone left over will have to adapt to the changing world." He didn't offer any more explanation than that.
The half-devolved nurse prepared both of them for the injection with an alcohol pad, allowing the doctor to get it done quickly and painlessly. In barely a minute, both of them felt a tingling senstion in their upper arm, and a slight intoxicated feeling. "You may feel drunk. That is normal, it's only your mind being rewired to that of a monkey. I suggest you embrace it and let the changes happen quickly."
"Thank you. We'll do our best!" replied Janet.
"You can drop your clothing in the laundry chute. It's still warm this time of morning."
The couple took their time to enjoy stripping their human inhibitions away. Since they were married, they've seen each other nude before and it wasn't that outlandish. As soon as Janet unlocked her bra and let her breasts fall free, Daniel's erection slipped out of the confines of his underwear, which he removed a moment later. No point in hiding his lustful feelings now. He leaned over and took his wife's panties in his hands, then tore them in two with a swift motion. Before they could continue, the doctor interrupted, "You may want to do that outside. I still need a sterile office, at least for the moment..."
