Caveman tries to fuck her

"You hot. Spoon," said the caveman with the hand-axe to the cavewoman with the shrewd eyes. The Professor could understand their speech because a translator chip in his head directly detected the brainwaves of any nearby speaking person.

Shrewd Eyes defensively crossed her nude legs tightly as she sat next to the berry bush. "Cock want fuck," she said, eyeing his boner suspiciously.

The man dropped his hand-axe and held his hands up in his own defensive gesture. "No fuck. Spoon." Just-the-tip really was the oldest trick in the book, thought The Professor.

Hand-Axe cautiously stepped toward Shrewd Eyes. He gently brushed his hard cock on her shoulder and started stroking her hair. "Spoon," he said softly.

Shrewd Eyes reached up, brushed her hand over his cock, and offered: "Wank."

"Spoon," insisted Hand-Axe, but he didn't object to the touch of her hand. His own hand caressed her face.

"Wank," insisted Shrewd Eyes, lightly running her hand up and down his cock, tilting her head to gaze up at him seductively.

"Spoon," he insisted, massaging her neck and shoulder. "Spoon feel good. Wet cunt."

"Wank," she insisted. She wrapped her recently-evolved opposable thumb around his shaft, starting to slowly stroke it up and down. "Wank feel good. Cock so hard."

He slid his hand down to her breast. "Like tits! Spoon, spoon, spoon!" he repeated with more urgency.

"Like tits? Wank, wank, wank," Shrewd Eyes countered, repeating the word in time with her repeating strokes of his cock. The Professor wondered if this battle of wills took place in every Erectus mating encounter.

Hand-Axe groped her breast and twitched excitedly in her hand. "Uhh… ahhh… spoon!"

"Wank," she insisted again, her eyes intensely gazing up into his. "Tits so hot... Cock so hard… Wank so good… mmm…" It seemed human language began with dirty talk!

"Uhhh… ohh…" the caveman grunted, his resistance wavering.

Shrewd Eyes smirked slightly. "Wank," she said with finality.

"Wank feel good," he admitted.

She ran her finger in circles on the sensitive tip of his dick. "Hunt, meat… then fuck. See?"

Hand-Axe nodded eagerly. "Fine! Hunt, meat, then fuck!"

"Good." She stroked his shaft faster. "Cock so hard… mmm... want cum…" she said in a sultry tone.

He moaned in pleasure. "Ohhh... cock so hard... like wank... feel good..."

The cavewoman's other hand reached up and rubbed his balls as she tugged faster and faster on his cock. "Want cum," she repeated. "Cock so hard... balls so full... cummm..."

"Oof... balls so full! Want cum!" he agreed, groaning needily, his cock looking bigger than ever.

She turned slightly towards him, to better display her busty chest and aim his cock right at it. "Want cum tits," she said seductively. "Mmm… Cum… cum… cum…"

That pushed the caveman over the edge. "Ohh, uhh, urrrrghhhh!" Rope after rope of thick slimy jizz flew out of his cock, painting her bare breasts and cunning face.

"You like?" Shrewd Eyes asked knowingly as she milked out his last spurt of wasted sperm, his breeding attempt successfully disarmed.

"I like," sighed the satiated caveman, his dick deflating. "You good wank."

"Hunt, meat, then fuck," she reminded him.

"Hunt, meat, then fuck." Hand-Axe nodded reluctantly.

He picked up his hand-axe and strode off with determination. Shrewd Eyes smirked triumphantly to herself.

The Professor was horrified by what he’d just seen. He debated whether it was time to intervene and teach her a lesson, or if he should keep spying and learn more about the culture he was trying to change.
