Starfields

In the skies of Ponyville, the house of a pony named Raindrops floated serenely, with not a care in the world. Inside, the beautiful mare lay sleeping, unaware of the events that would be happening that night.

"Ready?" Asked the leader of the team of three as he stood outside of the entrance to the house. Standing on a floating structure made out of clouds was a new experience, but not particularly a shocking one.

"Ready. Let's get this bitch." One of the men replied.

"Remember, no damage." The team leader said. "We want her fit for the experiments."

All of the men nodded, and the leader quietly opened the door, silently slipping inside. Their footsteps made no noise as the team of three commandos crept through the house, headed towards the bedrooms. As soon as they reached it, the team leader quietly opened the door, creeping inside of the bedroom.

The mare was a light yellow, her teal mane contrasting perfectly to it. She was beautiful, and that was why she was wanted for the project.

The mare rolled over, mumbling in her sleep as the leader approached. The multitool on his arm glowed a dark blue as it scanned the mare, searching for defects. None were detected. She fit all of the profiles: Beauty, virginity, gender, and being alone.

Slowly, the leader took a small needle out of a compartment on his leg, bringing it towards her throat. He stabbed it into the vein on her neck, the sedative immediately introducing itself to her blood stream. The mare suddenly woke up, her mouth opening in a scream, but no sound came out. Moments later, she slumped down, out cold.

Raindrops slowly opened her eyes, the white walls of the room brightly shining on her. She suddenly snapped her head up, looking frantically around, her strange situation settling in. The room was five meters across and long, and three meters high. Her hooves were on the ground, locked in place by some kind of metal, both of them spread wide. A brief blush coated her face before Raindrops snapped back to reality.

"Subject one is awake and aware." A voice suddenly said from several loudspeakers, terrifying her. "Test will begin in two minutes."

"Who are you! Why am I here?" Raindrops asked frantically.

"Subject name: Raindrops. You are to be part of an experiment organized by the URMS." The voice said, raising even more, horrifying questions.

"What kind of experiment?! Why am I here!" She screamed.

"I am not at liberty to say." The voice replied.

Raindrops screamed. She screamed until she had to take a breath, drawing the air in and preparing for another one. The door slid open, the noises catching in her throat as she whipped her head around. In the doorway stood some kind of creature. It was bipedal and completely nude, a blush forming on her cheeks before a feeling of dread set in. She tried desperately to move her hooves, failing, as the creature moved around behind her.

"Begin test on Subject One." The voice said. "First part of the test: Minimal penetration."

Raindrop's eyes opened up in horror as she processed this. "No! No! Please, don't do this! I didn't agree to this! No, please don't- AH!"

Raindrops almost screamed out as her tail was raised up, revealing her marehood. A thick rod immediately began rubbing itself on her lower lips, bringing a small stream of pleasure to Raindrop's mind. She had leaded about this in school, but had never done anything to touch it, preferring to wait for a day when she found a nice stallion.

The evil thing finally started to push itself in, meeting intense resistance as Raindrops tried her best to block its passage. It met her inner barrier, the one thing she had left blocking its progress. It stopped as it pressed against it, pulling back out until only the tip remained. Raindrops sighed in relief, thinking it was over, before the immense rod thrusted back it until it hit the barrier. It pulled out again, repeating the process. She let out a loud moan, the pleasure from the repeated thrusting almost overwhelming her.

"Full penetration is authorized." The voice said.

The throbbing cock slowly pulled out, leaving Raindrops panting in place. It suddenly shoved itself forward, breaking through her hymen and causing her to scream. Blood and her fluids slowly dripped out of her hole as the rod continued to fuck her, the tip brushing against her cervix at every thrust.

After several minutes of this, it slowed to a halt outside of her cervix, before slowly pushing in. Raindrops screamed as the cock violated her last bit of resistance. The rod began to move back and forth as the creature behind her hilted itself inside of her cervix, the massive member sending intense and conflicting feelings of pain and pleasure through her mind.

The speed of the thrusts grew, as did the force, until the cock was burying itself deep inside of her womb with every thrust. Slowly, the speed grew, until suddenly it stopped, with the member deep inside of her. She screamed as her orgasm barreled not her full-force, clenching her tight cunt around the invading member. Raindrop's mouth opened wide as she felt dozens of spurts of cum filling her womb to capacity, continuing to fill her up as the member started to pull out. Finally, it exited, spraying small streams of the white substance over her back and rear.

Raindrops panted hard, almost completely overwhelmed by what had just happened.

"Send the second tester in." The voice said, at a volume she barely heard. "Use her second hole."

Raindrops did not react as another one of the creatures walked in, coming around behind her. She let out a small moan as her used cunt was suddenly filled with another member, the tightness of it sending multiple signals of pleasure to her brain. It thrust inside of her for a second seconds before it pulled out, pressing itself against her anus.

"No..." Raindrops whispered as she began to resume her struggled, trying desperately to escape her bonds. It was of no use. The massive cock slowly spread her tail hole, the lubricant from her other hole providing it easy passage. She opened her mouth in shock as the sheer pain and pleasure from having her tight plot violated reached her. Raindrop couldn't decide if she was in pain or rapture as the thing continued inside, only stopping once it hilted all eight inches inside of her.

The member slowly drew out, her anus clenching at it as it left. It stopped as it finally left, only the tip brushing her tail hole. Suddenly, it move forward again, stretching her anus back out. Raindrop threw her head back, screaming out as the massive member pushed forward until it hilted itself.

The rod slow started to fuck her, the tightness of her plot constantly stretching itself around the invader. Raindrops couldn't do anything but take in the pleasure as it violated her sanctuary, speeding up as the walls grew slicker.

Within five minutes, it was pounding deep inside of her. Raindrops was reduced to taking short breaths between thrusts as it violated her hole. It sped up, faster and faster, until Raindrops reached the point of no return. She screamed out in pleasure as her second orgasm overtook her, with her anus clenching around the cock deep inside of her. It suddenly hilted itself, spraying its seed deep into her anus and intestines as it slowly pulled out. Finally, it exited, spraying globs of semen into her tail, and on her back and mane.

As the creature left, Raindrops stood there, panting. The metal clamps around her hooves were suddenly released, sending her weakened legs falling, being her to the ground.

"Well done, Subject One." The voice said. "You have passed testing."

Raindrops could only curl up and start crying.
