Captain Hannah Smith and her team were awoken in the dead of night by a blaring alarm. NASA had detected a passing asteroid months in advance, but now it had suddenly and radically changed course toward the planet. As the object tore through the atmosphere government scanners picked up on a garbled transmission. The alien transmission continued after impact, and now Captain Smith and her team were sent in to investigate and quarantine the area.
The object impacted in a densely wooded region near the Canadian-American boarder. The team's helicopter flew over them overhead. Miles away form the epicenter the woods became a grove of scorched trees, then barren dirt, then finally a crater deep enough for a building. buried in the center of the crater a massive metal structure barely even scorched from entry.
"Holy shit." One of the men muttered.
"Aliens, I fucking called it! Pay up Jack."
"Cut the chatter!" Hannah ordered. The excitement died down a little, only whispers continued as the chopper landed at the foot of the structure. "Jones, Lee you two keep watch out here. Nothing gets in or out. The rest of you with me."
Hannah and three of her soldiers readied their rifles and slowly made their way into the structure. The inside of the craft was dark, the team navigated using their flashlights alone. The entire structure seemed to give off a hum just at the level of human perception. The halls of the ship were claustrophobic, layers of dust hid dried blood stains and scorch marks on the wall from what could only be weapons fire. As they pressed deeper they could hear the transmission the scanners picked up. They followed the unintelligible words, until they made it to the bridge. A lone console flickered and every ten seconds the message would repeat. A space suit laid limp at the controls half torn apart, flesh less bones dangled from the damaged areas.
"Must have died a long time ago. Not even a smell." Sarah, the team medic, said.
"Yeah I don't think there's anything left alive on this ship." Hannah agreed. She tapped at the controls. They were written in undecipherable symbols, but she lucked upon the right one or sequence and the lights to the ship buzzed to life. "Alright, everything probably long dead but stay focused. We still need to sweep the ship." The squad split up again and Hannah and Sarah explored the ship. After hours of nothing, they came across one of the few rooms that powered more than lights. A lone silver container stood on a pedestal behind a red screen of light. The screen flickered and buzzed, worn down by possible centuries of overuse. Hannah reached out and touched the screen. A burning zap of energy sent her hand flying back. Hannah swore in pain, but the touch had used the last of the forcefield's juice and it faded away. Hannah examined the container it didn't have any obvious point to open it.
"I don't think we should be messing with this." Sarah said sheepishly.
"Nothing on this ship worked except the forcefield whatever is in here is important. HQ is going to want us to secure it." Hannah said dismissively. Hannah placed her hand on the silver container, and a glowing seam appeared. the seam spread around the top of the container, making it open. As soon as it was open a fine black mist shot outward. Hannah coughed and covered her face but it was to late. The black mist had filled her lungs and her face was dripping with the black residue. Hannah's vision faded and her legs wobbled underneath her, she could hear Sarah talking but couldn't make out the words, then she collapsed.
Sarah tried to call into the rest of the team but her radio signal was blocked by the ship. She monitored Hannah's vitals and cleared the mist off her face. Hannah shook violently, her limbs convulsed. Sarah did what she could, but without knowing more about the mist there was little she could do but watch and wait.Half an hour passed and Hannah groaned in pain, but woke up. her hands fumbled trying to lift herself up. A warm sensation tingled inside her. She looked up at Sarah, who smiled seeing her Captain awake again.
"Captain, you got hit with some airborne chemical. I don't know what it did to you, so how do you feel?" Sarah Asked.
"A bit woozy but other than that I feel fine." Hannah said as she rubbed her head. Sarah once again tried the radio. Hannah looked at the medic, even with the military fatigues she could make out the woman's features. Hannah found herself starring at Sarah's ass, her breath grew heavy and her eyes glazed over. her body moved against her will, standing up up and silently creeping forward. She could feel something in her crotch, something pulsing, straining against her pants. her arms ripped away at her clothing revealing a massive cock protruding from her vagina. Partially her white skin tone and partially the same black hue as the mist it was anchored in place with black veins visible beneath her pale skin. Hannah tackled Sarah to the ground and knocked away her gun. she couldn't stop herself if she wanted to and part of her didn't want to stop. She pinned her subordinate beneath her. Her arms moved with a new superhuman like speed and strength, tearing away Sarah's uniform and pinning her arms in place.
"Captain! What are you doing?" Sarah shrieked.
Hannah only moaned lustfully in response. She spread Sarah's legs and plunged into her pussy with her new cock. Hannah shivered in pleasure. Her primal lust pushed her to thrust in deeper and harder. Sarah was powerless beneath her infected captain. She could only cry out for help, but no one could hear her. Hannah pumped into Sarah grunting like an animal. Hannah was also powerless to stop her body, she could only watch and feel the her body fucking Sarah. The sensation was as pleasurable as it was horrifying. Hannah arched her back and her alien cock erupted. Sarah passed out under her, either from exhaustion or some chemical in the alien cum. Hannah could feel herself in control again. She looked down and saw her cock buried in Sarah. She could feel it pulse and throb already ready to fuck again. She bit her lip, the lust filled her body again. She looked away in shame, it was wrong but it felt natural to her now. She didn't want to fight it anymore. Hannah turned back to Sarah and smiled with perverse glee. Thrusting into her again.
