"We'll have sex in a little bit," said Janet. "First we should show Oliver our new selves." Daniel grunted his approval, taking his hand off his dick temporarily. But it would be right back there after a few seconds. Since Janet's memory of driving a car was fading fast, she decided they would just walk instead. When they walked out into the street, it seemed everybody else also had the same idea. The streets were unusually empty of cars, and folks were strolling down the streets like they were sidewalks. There were even some who were stark naked, even if they weren't about to transform. One handsome young man was sitting on the curb and getting a blowjob from a young lady, and nobody else seemed to care.
Abut halfway to their destination, the cloud cover faded away and the city was left to endure hot and humid weather. Both Janet and Daniel were intoxicated by the heat and found it hard to concentrate on finding their way around town. "Guh, so warm. I sweaty." mumbled Daniel, as he wiped his furred brow. "I know, but we're already as naked as we can get..." replied his wife. That is, until she felt a familiar tingling in her extremities. Humidity doesn't do that to you! Especially when it's localized mainly in your back and feet. This was a wave of transformation.
Calmly and curiously, Janet observed herself changing again. Her big toes spread out and became the thumbs of monkey paws, able to grasp and swing from trees with ease. A moveable tail sprouted painlessly from her back and was covered with fur in seconds. More fur followed suit, growing over most of her body, even her face, framing her features. Even her skin tone darkened slightly. Daniel was amused by this and laughed to himself, unaware that the same things were happening to his own body. And after his toes and tail and fur came out, he changed even further-- his forehead receded, and his jaw pushed itself out which made his laughter sound more like animalistic hooting.
At this stage, Janet was visibly devolved and Daniel barely looked like a human at all. It took Janet twenty seconds to remember any English words at all. And all she could come up with was, "No! Monkey no two days! Monkey two hours!!" Daniel just scratched and rubbed his cock, looking unworried by anything that was happening to them. "Want sex! NO! Want Olive!" grunted Janet as she took him by the hand. "Me tell Olive news!" But even if Janet was in a hurry, one naughty hand was already creeping toward her vagina.
