extreme beastiality

The alien was a member of a highly evolved race who unbeknownst to the world's public, had just conquered the earth. They privately demonstrated to the world's major powers just how futile an armed conflict against them would be.

However they would allow us to continue governing ourselves provided we provided them with human females with which to breed alien/human hybrids. Over the last few hundred years, their females had been slowly growing sterile.

All their scientific knowledge couldn't stop this and finally all their females became sterile and no longer capable of producing offspring. Trying to reproduce strictly through genetic engineering wasn't a solution and there very DNA started showing signs of inevitable decay. So these hybrids would eventually produce a new race and provide a way for their civilization to go on, although in a different form.

When doing tests on abducted humans, they found that even genetically mutated male human sperm could not fertilize their females. However male alien sperm when genetically altered, was capable of impregnating a human female. However no physical sexual contact was nessesary to produce offspring. It could all be done in a science lab.

However when one of the alien males decided to try psychically mating with a human female, he quickly discovered that mating with women was much more pleasurable than with their own kind. Other alien males found out, and they insisted in actually mating with the women. So the female staff at the various facilities now had to deal with horny alien males literally jumping the female staff.

Karen, the head researcher of the facility was in late with only a young female assistant working with her in the lab. The girl, fresh out of college. Had already been shown taped video footage of women having sex with the very alien currently in their lab. The Alien being had been following this young research technician all day around the enclosure

So as Karen sat quietly reading a report in the control room, she was surprised to see that the girl was quietly entering the aliens enclosure. Through a concealed video camera, Karen saw the girl checking to see if she was alone. The girl then walked straight into his enclosure. Though obviously pleased, the alien kept his cool about her being there and approached her calmly.

To Karen's surprise, the girl then started to strip. Once naked, she was quickly on her hands and knees waiting for him. The slightly larger Saurian then mounted her with great gentleness. His midsection was now nested against her back. His genital area was slightly behind and above her firm round buttocks. She then bent her back downward slightly, which raised her butt cheeks upward inviting the male's organ into her.

His large sex organ slipped out from the slit on his lower abdomen, and the tip of his member probed at the gap just at the base of where her buttocks separated and her vaginal opening lay.

The insertion was very gentle and slow as the 8 inch thick, ribbed organ began to slide into the girl. A moan escaped her lips as it was buried deep inside of her. The smoothness with which the two only distantly related species had coupled was amazing.

Slowly at first and then with increasing intensity, a behavior their species shared then set in. That being the rhythmic thrusting of copulation. Her outer and inner labia clung to the massive organ as it was pumped in and out of her. The mating was very human in duration and surprisingly tender.

It was obvious to Karen that the girl was enjoying the sex. The girl was rhythmically raising her butt in response to his shaft being plunged into her from behind. The girl's breath occasionally got caught in her throat as the male organ was driven into her eager and willing body. He was breathing hard too, his lust being expended on his mating partner.

Finally, the girl climaxed. Her head dropped, and she let out a long, slow extended breath. As if blowing on a hot bowl of soup. However the Alien wasn't finished with her. He lifted her up onto a table. She then laid back and spread her legs apart. Her neatly trimmed pubic hair barely covered her labia that hid her moist vaginal opening. Her lean body heaved with breathes of excitement as she waited for him to enter her again.

She litterally jumped as the tip of the warm moist organ made contact with her wet pulsating pussy. The alien then gently grasped her calves and spread her legs apart and pressing her knees up towards her chest. Then he slowly entered her willing body.

The Alien could feel her vagina open and stretch as he slowly introduced his member into her. It was very warm, but he was having trouble getting the entire 8 inches of his thick member into her. However shortly after it squirmed around a bit, this stimulation increased her production of vaginal fluids, and it quickly slipped completely inside her.

The alien then finally began to aggressively fuck her. Occassionally his member would slip out and he'd reinsert it into her. The alien as always was fully enjoying mating with a human female. Her vagina was comfortably tight so that her vaginal walls pressed tightly on the shaft and caressed it with gentle muscle contractions.

Her labia clung to the slowly pistoning organ as the ring of muscles around the vaginal orifice gave extra firm squeezes. Karen was mesmerized by the sight of these two beings locked in mutual pleasure. Suddenly her hips began to thrust more aggressively as she slowly rose to her first orgasm.

As she peaked repeatedly under the tenacious, but slow and tender, thrusting, she began making small grunts as each breath was expelled. Finally, as his own pleasure became too much, the alien slowly decreased it thrusts and ejaculated inside her. He then pulled the organ from deep inside of her leaving her vagina gaping open briefly and then it slowly collapsed, her vaginal lips still distended and wet with the juices the animal so efficiently brought from her.

She layed back exhausted with her legs still spread. The Alien, now satisfied, turned away leaving her still breathing heavily on the table.

Karen immedietly wondered how to broach the subject of what just happened with the intern in the morning. Although it was an unexpected turn of events. The real question was, how would the girl react to the news that her alien partner had been recently engineered to impregnate human females.
