Jill and Jane were cute, twin, 11-year-old girls who lived in New Mexico. Bothe girls were lithe and flexable, cute and blonde, and had mottor mouths to match their excess energy. The girls were playing tag in their back yard when they noticed a light moving across the sky.

"Hey Jane it's a shooting star, make a wish." Jill said.

"Uhh Jill, if it's a shooting star why is it heading straight for us?" Jane asked.

The twins held each other's hand and screamed, as the bright light in the sky grew larger and larger as it rapidly approached them. Soon the light seemed to completely engulf them and the twins blacked out.

Jane blinked her eyes adjusting to the light. She was strapped to a medical table, her cloths where gone. Turning her head to the right she saw her sister was also naked and strapped to a table. She heard footsteps approach and was shocked to see a gray skinned alien with big eyes and a frail slim body. Jill rustled and regained consciousness. She gasped at the sight of the ugly naked alien.

"EEEEEEEEK!!! What are you?" Screamed the twins in unison.

The alien winced at their shrill cries at first but then responded "Greeting Earth girls, I am Leb."

"What do you want from us?" Jill asked

"I have come to Earth in search of female human sex-slaves." Leb explained.

"Sex-slaves?" Jane asked.

"Yes I'm going to use you in each and every filthy perverted way I can come up with then I'm going to ask other people for suggestions. When I've tapped out that gold mine I'll go online and see what kind of filthy perverted things they can come up with there. After that I'll return you here and find a couple other pre-teens to tap." Leb stated matter-of-factly.

Both sisters struggled hard against their bonds but couldn't escape. There was a strange buzzing sound as a hovering orb with a camera fixed to it flew into the room. It was followed by metallic footsteps as a human looking robot walked into the room. For all intents and purposes it looked like a cute, shiny, smooth metal woman except "she" had a metallic dildo protruding from her lower midsection. Leb placed a hand on each of the struggling girl's foreheads. He began to use his psychic power. The twins felt their control sapped from their bodies, they could no longer resist Leb's commands, while they remained conscious and aware of their predicament they would no do anything that they were ordered to. Leb released them from their straps.

Leb smiled. "Jill get on all fours, AK3-0 fuck her good. Jane get on your knees and suck me."

Jill went to all fours obediently. AK3-0's metal penis began humming and vibrating. The robot placed her hands on Jill's hips, and then with a powerful thrust slammed her metal prick into Jill's cunt. The metallic dildo ruptured her virginity like a truck rolling over a baby turtle.

"EEEEEPF" Jill squealed.

The Camera spun to Jane who was licking up and down Leb's swollen shaft. She took the dick into her mouth and sucked as hard as she could while using her tongue to tickle the shaft. Leb thrust his cock in and out of her mouth while the girl's full lips clamped firmly around his alien fuck-meat. Leb moaned as he vigorously face fucked the teenager. Jane, deep under mind control, was sucking with all of her might. Leb's pet hermaphroditic robot AK3-0 meanwhile, was power fucking the other twin. AK3-0 pistoned back and forth slam-fucking the squealing girl till she could take no more. Jill's boobs wobbled back and forth as her cunt was battered by the robot's spinning and vibrating metal rod. AK3-0 soon fucked Jill to a raging orgasm and then kept fucking her even as she went limps and it seemed the robot was simply fuckind a limp unconscious rag doll. AK3-0 seemed to think Jill had had enough so she released the girl who collapsed into a heap on the cold steel floor. Leb meanwhile felt the pressure building in his nut-sack he felt an orgasm coming but did not want to cum in her mouth. The alien grabbed Jane's hair and pulled her head off of his dick. Her suction on his dick making an audible "POP". Leb moaned as he squirted his foul smelling green-white cum on the pretty black girl's face. Leb heaved, his breathing labored. Soon he regained his normal breathing. He looked over at Jill who's eyes were fluttering and was breathing hard. He stroked Jane's hair as one would a pet and pointed at the girl's twin sister.

"Now Jane its time for you to put that talented mouth of yours to more use. Jill roll over and spread your legs. Jane eat your pretty twin's pussy out."

Jane felt disgusted at the idea of eating out another girl especially her own sister but she could do nothing. Jane crawled over to Jill like a dog she spread apart Jill's legs. Jane brought her face close Jill's battered and beaten pussy, her sister began to stir as she felt Jane's cool soothing tongue on her hot cunt. Jane licked the outer lips of Jill's sopping wet pussy clean. Jill sighed and moaned in pleasure and absently played with her boobs, Jane then plunged her tongue into her sister's honey-hole while kneading her firm ass cheeks. Jane tongue fucked her sister Jill's love box until Jill came to a second moaning orgasm. Since Jane was already conveniently bent over Leb had AK3-0 hand him a glowing green rod the burned and glowed. He spread Jane's cheeks and began feeding the burning green rod into the girl's tight ass. Jane howled in pain as the painful burning rod violated her ass. Leb cruelly raped the crying girl with a few strokes before pulling out his probe. A little blood drooled from her ass much to Leb's amusement.

"Yes my human fuck-toys, you are most enjoyable and look I am hard again! You there, Jill get on your hands and knees." Leb ordered.

Jill slowly obeyed. Jane watched miserably as Leb approached her twin sister. He spread her cheeks and pushed his cock into her wet hot cunt. The alien began to fuck her enthusiastically. She whimpered and her boobs jiggled and swung in time with his strokes until he finally filled her pussy with his warm alien cum. Leb slapped her ass and pulled himself free.

"AK-30, please take my fuck toys to their cages. I am going to find some more humans to enslave and join these juicy little twins in my personal harem." Leb said.

With that AK-30 placed collars around Jill and Jane's necks and led them to the cages that would become their homes for months to come.
