Alpha does good work.

Brugl 3 was sitting in a big room. Before him was a console with many shimmering sensor fields. Six big holographic fields showed Sue Richards from different angles and different details of her body. On other display fields changed readings and data from the experiment.
If a creature like Brugl could be pleased, than he was it. When Sue was **** they had scanned her body and found many interesting changes to their other specimen from this place. Even her Mind was different. Because of the so totally different anatomy of humans the Aliens had made some mistakes.
When they sent in the servant creature they where waiting for some wrong results. It began with the Idea that Sue would it like to be totally helpless. Then they had estimated that for a human woman like Sue her mate should have a penis with at last 14 inches lenght and a diameter of 2,5 inches with a rough skin.
So they sent Alpha, which had such an Organ.
Brugl 3 now was waiting what happened. And he thought that the faint sounds that the Woman produced where signs of pleasure.

Sue had only heared some soft sounds, when suddenly she feeled probing Fingers on her Skin. She wanted to speak but she only could moan. The powerful touches of the Alien she couldn´t see where unpleasant, especially when the strong Hand roughly grab her boops. Then touch of the slimy rough Tongue on her Skin was disgusting. The Air was filled with a foul smell.
Sue began to sweat despite the cold air and she moand loud when the Creature sucked at her Nipples like it would rip them from her Breasts. The Tongue licked further over her Body and finally touched her Pussy.
Was it the helplessness, the touching, the fear ? Sue was breathing heavy and felt the Tongue at her Clit. She felt how she get wet. The Tongue felt disgusting, but it was very long and flexible and played very skilled with her Flesh. Suddenly the creature moved and to her great horror she felt him press the tip of his Penis against her Vagina. He rubbed the rock hard and rough Tip of it against her Slit and Sue tried to move. Suddenly and with unbelievable power he trusted his gigantic organ into her Pussy. She felt as if the massive Organ would rip her flesh apart. His Cock was gigantic. The pointy tip of his penis rammed hard into her Vaginal canal and penetrated her Womb. With his first Thrust he rammed his entire Cock in the helpless Woman. Sue fought not to be black out. Then he pulled his organ back and the pain weakened before the invisible girl suffered the most powerful, hardest Fuck of her previous life.

Alpha was pleased. This female was so soft and nice. The **** fields that held her made it easy to penetrate her entrance, because she couldn´t move. So he could push his cock in long, deep thrusts into her. It was a nice feeling when he was complete in her and his Tip pressed against the wall of her Womb.
His Masters had commanded that he should work slowly. And so he did. His Thrusts where slow but powerful and only after long minutes of fucking he **** his speed.

Sue doesn´t know why but she was all the Time awake when the Monster **** her. Every thrust of his monster cock whipped waves of pain through her stretched body. But she don´t found the mercy of a black-out. For Sue it seemed like Hours that the Alien creature fucked her. Her skin was sore scrubbed and her bowels ached with every of his deep thrusts.
Suddenly he stiffened and then a explosion of cum flooded her Womb. She felt his sticky, hot Fluid gush into her Womb, fill her to the limit and then pressed its way through her vaginal canal. The volume of Alphas cum was too great for the slim woman's body. Nearly a quart of Cum pumped Alpha in the helpless woman. Then he withdraw his cock and looked at the gaping hole of the Female. He was proud. He had done a good Job. She was filled with his seed and it was a interesting look when it ran out of her vagina because her slim body couldn´t hold all the stuff.
Suddenly he „heared" a signal. His Master seemed glad too. But now it was Time for the second Part. With proud delight Alpha prepared for the second task.

Brugl 3 was discontented. The readings from the Experiment weren´t of that kind he expected. Some where to small, others different from his calculations. He must change some parameters and continue with the experiment. Alpha had done a good Job. He would let him perform the second Task as well.
He changed some settings and then gave the Signal for Alpha. Now it would interesting to see how the Human Woman would react when the Changes take effect.
