Penetration!

“ZZZZZZZ.....COMMENCE EXAMINATION.....ZZZZZZ”

Mary Lou opened her eyes, and found herself in a room seemingly made entirely out of white metal;. She stood on unsteady feet, blinking the gumminess out of her eyes. She pressed her hands against the walls, and found they were slick, almost like soap. A faint hum could be felt coming through the other side.

“ZZZZZ...STAND STILL....ZZZZZ”

The voice came from above. She looked around, but couldn’t see any speakers or comms. “Hello!” she called out. “Where am I? Who are you?”

No answer came, only a series of thumps from beyond the walls. Her skin began to prickle. Something was about to happen, some deep primitive sense that warned her....

Panels opened on the door, and from each came out a long metal arm, round clamps on each end. They grabbed Mary Lou where she stood and hoisted her screaming upwards. Let me go!” She screamed. “:Oh God help me!”

Another panel opened from the ceiling, and a glowing orb dropped. For a moment it hung there, and then a beam of green light shot out. Where it touched her clothes, it disintegrated the cloth, her jean shorts and tank top turning into dust that fell off her body, her bra and panties quickly following suit. Within moments she hung there, naked as the day she was born, her lush young body squirming against the clamps, her breasts heaving. “What are you!” she screamed.

“ZZZZ.....EXAMINE ALL ORIFICES...ZZZZ”

“Wha...no. NO!” A round hole appeared in the wall, and from it came a pair of long, black metal shafts, each at least a yard ling and quick thick. They floated across the room, one taking position behind her, the other in front. Droplets appeared on the rounded heads of each, and quickly spread to cover them all. Lubricant, she realized.

Then, at the same time, they violated her, one pressing into her ass, the other into her cunt.

“NNRRHGGGAAAAH!” She screamed aty the top of her lungs, pain searing through her body. The lubicant prevent tearing, but the sheer size was shocking, bigger than anything she had ever seen. It stretched her horribly, her body bulging at the sheer size.

“ZZZZZ...SUBJECT FEELING PAIN. ACCESSING PLEASURE CENTER OF BRAIN...ZZZZZ”

Mary Lou gasped, as, beyond her understanding, a wave of sexual desire thunder through her. To her horror she felt herself grow wet, felt her body respond to the intrusion. The shaft in her cunt began to buzz, and she realized it was vibrating. Her skin flushed, her nipples hard as rocks, and she breathed heavily, moaning through tightly clenched teeth.

Both shafts began to pump back and forth into her, stimulating her nerves, her own body betraying her. All to quickly it was over, and she screamed out her orgasm.

“ZZZZ....SUBJECT AS ACHIEVED CLIMAX....PROCESSING DATA.....ZZZZ”

The shaft withdrew fro m her body, the clamps released, and Mary Lou fell onto the floor.

“Her reacting was amazing.”

“Do you realize out own ancestors were once like that, in their primitive lusts.”

“How distasteful!”

“Yet strangely...exhilarating....”

“We must find more subjects at once.”

“I agree. And we must find males of the species as well.”

‘Yes...they will suit our purposes nicely.....”
