It had been an average shift on the ward when Sister Cebra had first seen the kid. Small, skinny, clothes tattered and burned, he walked in from the freezing night and into the soft glow of the Medicae building. An orphan, she thought, 16 or so. Lack of nutrition and the cold air already starting to turn his bald head the faintest purple. Bruises and scratches covering every visible inch of his skin. She rushed to his side, wrapped him in a blanket, and pulled him into one of the rooms. He was quiet, almost catatonic, his body barely responding to her touch as she checked his vitals. She tucked him into bed, rushing out of the room to fetch hot caffeine and an easily digestible nutrient bar.
When she returned, he was sat straight up in bed, his dark eyes staring at her. She spoke to him, gently, explaining who she was and that she was trying to help. His eyes didn't move. She inched closer, holding her arm out, the nutrient bar unwrapped. She felt her heart pounding, although couldn't work out why. Just another traumatised kid, on a planet full of them. So why did he feel so alien?
She moved, closer, and he darted towards her, his arms shooting out to grasp hers. She screamed, pulling back, but not before he grabbed the bar out of her hands and started stuffing it into his face. Just hungry. He was just hungry. She edged back to the bed, taking deep breaths.
 “Would you like-”
 Pain flashed like lightning, and the room went black. She sprawled on the floor, and everything tasted of blood. She tried to raise her head, tried to piece together what had happened. The room returned to focus, and she saw him, standing on the bed. She reached for the bolt pistol at her waist, drew it, aimed it at his head. And then everything stopped.
The room began to fade around her, folding in on itself, everything except the creature itself blurring together. She tried to move, tried to fire her weapon, but nothing was happening. Burning rage filled her, a white hot frustration fighting against the thing invading her mind. And then it spoke to her mind.
Don't fight it.
Her finger twitched. She was so close. Just a little further.
It will all be over soon.
She felt her arm slacken. The creature moved towards her then, dragging her to the bed and pinning her there. One hand found her head and held it down. Another pawed at her chest, ripping the white bodysuit she wore when stationed here. Then she felt something else, something at her hips, a third arm tearing through her robe. It felt less human than the other two; harder, and colder. It's talons shredded her undergarments, leaving her completely exposed to the alien entity. It moved its mouth to hers, and kissed her. She felt its tongue enter her mouth, slide over hers. It left her mouth, trailing down over her chest, leaving new sensitivity wherever it touched. Her body began reacting fiercely to the alien toxin, her cheeks flushing. It didn't take long before she was ready.
The creature's hold over her mind faltered as it pushed its way inside her. She regained just enough of herself to struggle, to try to fight back. But it was far stronger than her, and pushed her back down. Tears welled in her eyes as it began to slide into her, and the hold it had over her mind and body returned. She tried to fight it, filling her mind with images of the emperor's light, but she could not. Her eyes rolled back as the sensations became overwhelming, and the creature began to unload itself inside her. She arched her back as she felt a wave of pleasure building inside her, and when it broke her mind did too. She was his.

Sister Cebra awoke to a new day, and a new mission. Her master was sleeping in the observation room, and something was growing inside her. But that wouldn't be enough. She had an entire ward of patients and hospitaliers at her disposal. She would bring the women to him. And the men, she would use their seed herself. Her work was only beginning.
