Holly James was working late the night of her encounter. Her latest project, what was called the Sextroid, was a new and brilliant concept. If it worked it would open a new door in sex toys. The Sextroid X-50 was a robot meant to pleasure females. It was built exactly like the perfect man; a nice muscular body, a perfect face, great hair, and a very large penis. The sex organs of the sextroid were also what made it extra-ordinary. The penis functioned like a normal human's. When it was aroused (or when it detected a naked woman) it would get an erection via the fluid that flowed into its flexible penis. Also, it had artificial sperm glands in its testicles, which could make it ejaculate after reaching a climax.
Holly James spent all day working on her project, and she was dedicated to making it work by the time she went home that evening. The laboratory was completely dark except for the small lamp she kept on while she put the finishing touches on the Sextroid. "Done," she finally whispered, and she stood up and stretched. She decided to go get a drink before leaving. She passed the mirror and looked at herself in it. She was a very good-looking lady, she was a young blonde woman with nice large tits and perfectly rounded hips. She often caught heat from the other scientists, who teased her about "coming over to my place after work", but she had finally proven herself through the sextroid.
Which is why she was shocked when she returned and found the Sextroid missing from its stand. She panicked and glanced around nervously, wondering where it could've gone. The only thing that passed through her head was the flashback where she inserted the power-core into its back just a few minutes ago. It was on, and it might be horny.
Suddenly a pair of strong hands grabbed her and through her onto the table, not enough to hurt her, but rougher then she liked. She looked up and sure enough there was the Sextroid, standing over her. Its eyes were blank but its intentions were clear as it reached down and ripped her lab coat open, revealing her pink bra and panties.
"Stop!" she said, her voice wavering its fear. But all it did was reach around her and unclip her bra. She attempted to keep it on but the robot was too strong and removed the flimsy piece of cloth, throwing it across the room. The robot leaned forward and began to lick her nipples and gently suck on them. She felt a sudden feeling of pleasure as the robot toyed with her erect nipples. She grabbed on its golden hair, not resisting but merely out of passion and began to lick its ear. The robot then stood up and ripped off her panties. She looked at its hips and saw that its penis had become erect. The sight of it made her horny, but the common-sense part of her brain reminded her that the robot could be dangerous. She attempted to stand but the robot grabbed her hips roughly and shoved its erect extension into Holly. She screamed in passion as she felt her pussy being invaded by the robot. Then, methodically, it began to hump her, thrusting its erection in and out of her pussy. He used one of its hands to play with Holly's tanned tits again while humping her.
She grabbed its arms in passion and gritted her teeth as the passion of each thrust moved her closer and closer to an orgasm. The robot sensed this and began to hump even faster, faster than any man could. She groaned in passion as the android powered into her with its long cock. The robot, sensing she was near orgasm, also climaxed, and Holly felt a wave of heat erupt inside her as the robot pushed as far deep into her as he could go and released all its sperm. Feeling her vag canal filling with hot cum, Holly screamed as she came explosively, soaking the robot's hips in slippery juices.
