Homo Erectus (East Africa, 900000 BP)

The Professor travelled back to 900,000 years ago. He knew it was a time when human population had shrunk to nearly the point of extinction, and Homo Erectus had started evolving into Homo Sapiens. He wanted to breed submissiveness into women from the very beginning...

With so few humans alive, they were hard to find. The Professor had to teleport around to many different locations using his wristband device.

Britain was an uninhabitable ice landscape like Antarctica. Ukraine was a cold, windy, treeless climate like Siberia, roamed by mammoths bigger than any elephant he had ever seen. China was a barren desert. And everywhere he went, the sky was ominously obscured by a high dusty haze. Clearly Earth had been hit by an asteroid and was deep in an ice age.

Finally he teleported to Kenya. This time he found himself in a grassland climate, warm despite the dusty sky. He wandered through the vegetation, alternating between grasses and trees. He occasionally saw a big cat and sneaked away clutching his wristwatch for dear life.

There must be humans here if nowhere else, he thought as he walked on, getting tired.

He was sheltering under a group of trees when he spotted her. A female Erectus. Technically scientists might call her Homo Heidelbergensis, but evolution never draws clear dividing lines, and Erectus sounded sexier.

The woman was totally naked, innocently unashamed of her curvy body as she sat there picking berries. The Professor felt his dick twitch in his pants. In his excitement he stepped on a branch.

Her head spun toward the trees, looking for the source of the noise. He got a brief glimpse of her face before he darted out of sight. Her primitive ape-like features and scars weren't the most attractive by Sapiens standards, but she had a wild untamed charm. Her eyes were shrewd and suspicious.

But The Professor wasn't sprung. Shrewd Eyes instead focused her attention on an approaching male Erectus carrying a hand-axe. Living up to his species' name, his erect cock was sticking out in front of his naked body...
