The cold cell of your ship was your home for about a week at least, after you started a brawl in the cafeteria in front of some Ultra Marines; that behavior is unacceptable from a guardsman of the Emperor and now you were waiting to arrive to the next space port to be executed in public for that simple brawl.
In that moment you were quite enraged for the strictness of the Imperium of men, it is right to encage a man who bring troubles, but you didn't kill anyone of your colleagues, not even those you hated the most.
Your thoughts of hate were stopped by the whining of the alarms signing that someone has boarded the ship. It could be everything, from a pirate band to chaos forces and maybe this is the possibility to survive your judgement.
But suddenly the alarms stopped and you hear heavy footsteps outside the cell almost like a space marine was out there, then you hear the firing of some bolters.
You're door get smashed down as a huge chaos space marine in a blue armor walked inside with a whip in his hand. S. Marine 1: "Look what we got here, brother.* Another chaos space marine get inside, He glares down at you S. Marine 2: "This will do." S. Marine 1: "Are you sure? You know what could happen if we fail her." S. Marine 2: "Trust me, this will do."
The first space marine takes you by the arm and pulled you out of the cell. They are bringing you towards the bridge it seems and when you're there you see dead corpses of guardsman, engineers and ultra marines. The other chaos space Marines are indulging in pleasure.
They get you on the upper floor of the bridge where you see other Chaos space marines knelt down before a woman in a seemingly modified armor of the sister of battles, she is tall with a fit and curvaceous body and lean hair, a mask on her face covering her mouth. She wasn't wearing a power boot since a space marine was licking her foot with his long barbed tongue
S. Marine 2: "O great Anastessa, we brought you a gift."
Anastessa: "..." She doesn't even turn her head, she just push her foot against the long, barbed tongue of the chaos space marine that get quicker in the movements between the delicate fingers of the woman's foot.
S. Marine 1: "uhm...Ms Anastessa?" He called softly to not disturb her mistress while he held you down on your knees.
Anastessa: "..." She doesn't respond and some Daemonettes crawl closer to you in a predatory way while the first chaos space marine held your arm tight and pulled you behind him.
S. Marine 1: "It's not for you."
S. Marine 2: "Ms. Anastessa?"
The woman on the throne sighed heavily as she pushed away the chaos space marine from her foot and the Daemonettes crawled towards him pinning him down on the floor.
Anastessa: "Bring them here."
The first chaos space marine brought you before the woman still keeping you down on your knees as she leaned her foot closer to your face without saying anything, like she thought you were going to lick it without a direct order from her.
