Another voyeur shows herself

As soon as Hand-Axe left, a second nude Erectus cavewoman emerged from behind a bush. She also had nice curves, but a less scarred face and softer, cuter, more innocent eyes.

"Hot," remarked the new woman. The Professor realized he hadn’t been the only one spying on the sexy scene.

"See!" said Shrewd Eyes. "Spoon: man trick girl. Wank: girl trick man." She made a handjob gesture to illustrate her point.

Innocent Eyes just looked at her blankly. "Trick?"

Now that interested The Professor. Did only some of these women have the genetic tendency to manipulate men? This could be important information for his eugenic breeding plan...

Shrewd Eyes rolled her shrewd eyes. "You dumb," she said exasperatedly. "Smart rule: Meat, then fuck. No meat, then wank cock."

Innocent Eyes nodded her innocent face. "No meat, then wank cock," she repeated, but The Professor got the sense she was mindlessly reciting the rule without really understanding it.

"Good girl," said Shrewd Eyes.

Innocent Eyes got a silly submissive smile on her face (hmm, a big reaction to being praised, thought The Professor). She pointed to the other woman's cum-covered tits. "Lick cum?" she asked hopefully.

"Lick," agreed Shrewd Eyes. She pulled Innocent Eyes toward her, pushing her face into her chest.

Innocent Eyes stuck out her long tongue and flicked it over the smarter woman's breast, licking up the caveman cum. "Mmm... like cum." What a horny cumslut!

His cock was getting very hard now, watching the two curvy naked women discussing sex and swapping cum. The Professor debated which of the two cavewomen he should take first...
