The Neanderthal takes Sue as a mate!

The alpha male of the Neanderthals approached Sue. the pheremones in the air made her act instinctively, instead of according to her wits. She looked down submissvely. The other males hooted and hollered as their new "leader" sniffed the blonde hair of this woman who was different than themselves. The male groped her breasts. They reacted to the sensation and hardened.

Brugl 6 was finally happy with the results. The other aliens crowed the monitor room. It looked as if their new female human specimen was finally ready for the mating trials. Despite the fact that this was not her species, the DNA was close enough for a genetic match. The aliens watched in hopes that she would accept her "mate".

Sue's mind reeled. She still held onto some semblance of her humanity. This being was clearly a neanderthal, and not human. Her reasoning told her, she should not be attracted to this male...this strong male. As the creature pawed her breasts, that last thought seemed to answer her confused mind. The pheremones overwhelmed her senses. Her rationale changed to the most basest of thoughts. The man who was claiming her was a strong male. Her hands moved to caress his strong muscular arms. For some reason, her advanced human brain was being pushed into the background. All that remained was instinct.

The primitive man grunted at her touch. His body pushed up against hers. She felt his erection against her leg. His tan hairy skin pressed hotly against her own white hairless flesh.

The Brugls saw on the sensors that she was finally ready. They sent the order for the other suitors to leave the other two alone in the chamber. The new "couple" watched as the others trotted out of the viewing room. The alpha male seemed to understand what was to come next. He grabbed Sue's hand forcefully and pulled her to the center of the room. Sue submissively followed. This was the woman's place. She allowed herself to be pushed to the ground.

She met the creatures eyes as he moved on top of her. Her loins now burning in primal anticipation. Her only thought...MATE! He thrust forward with a mighty stroke. His large cock took some time to get used to, but Sue's body began to adjust. She wrapped her legs around her lover and humped up onto his shaft.

The aliens were finally getting the readings they had longed for, and now they began to take readings, and X-rays of how these humanoids mated. The aliens were surprised when the human female began to emit load moans. Before, this seemed to signal pain, but according to the readings, this was all pleasure.

The aliens had a camera which witnessed the mating on the anatomical level. And they were able to record the Neanderthals cock thrusting inside her human vagina.

The readings began to go off the charts with the female human. Her temprature rose, her heart beat grew, and a new reading began to eminate from her loins. It seemed to explode out from this point to all parts of her body. They saw the woman go stiff, her eyes rolled in the back of her head. And her body shook wildly as she moaned.

The Neanderthal's own readings were also off the charts, and when her own climax happened, the Aliens saw that the being was ready to release its seed. They had no idea the feeling of bliss the Alpha Male was truly experiencing as Sue's cunt gripped his cock like a vice, instinctively ensuring that all his seed would reach its mark. His cock erupted deep inside her womb, the Neandeerthal seed filling her womanhood.

After minutes of readings in the red, the aliens saw the pair collapse. The blonde human female used her lips to "kiss" the male over and over on the face. A sign of affection, the Brugls thought. They turned off the sensors as the pair embraced in a ball and drifted off.

Brugl 6 turned to his shipmates, "You see, some simple adjustments worked perfectly."

Brugl 7 inquired, "We must watch the females womb! To ensure we can record a full human gestation and birth!"

Brugl 6 nodded, "They will mate. I have no doubt of that. Yet, he is not of the same species. However, we will get out human birthing readings!"
