After thousands of years of absence, the Imperium of Man had returned to your world to collect its tithe. A census and genetic screening caught something in your biology of interest to their researchers. That's how you found yourself on an orbital lifter heading towards the hulking cruiser Omnissiah's Spear, alongside a load of other unfortunate souls. The terrifying sound of metal against metal rocked the small ship as it docked with the larger vessel. The airlock shunted open, flooding your nostrils with the scent of oil and incense. A host of servitors began processing the human cargo with rote efficiency. One read the barcode printed on your scalp, "560H-9σ, to Arch-Genetor Isrya Krane" The servitor then prodded you forward towards your destination. After a journey of a few miles through the labyrinthine ship, it shoved you to the cold floor of a laboratory before departing.
Doing your best to look around, you see that you're in a large space with metal examination tables and other blinking medical equipment. Without warning, a portion of the machinery stepped away from the wall. It was a cybernetic person in flowing red vestments!
"+Warm+ 560H-9σ, Greetings" the figure called out as it approached. Its tone was robotic, but still feminine.
"Fuck you, I'm ${name?}," you groaned.
"+Irked+ I am Arch-Genetor Isrya Krane. I expect your cooperation," she replied.
"With what?" you spat.
"+Formal+ Your genes are valuable to me. I will be collecting samples," she replied as a mechadendrite emerged from her robes and slithered towards you.
"+Reassuring+ Do not panic," Isrya warned before the cold metal appendage dived inside your pant leg. You tense up as it begins to examine your genitals. Her steel extremity wound softly around your shaft, giving it a skillful pump.
"+Delight+ Organ size is superlative," she observes, "you will provide me with many samples."
You try to pull the metal tentacle away, but its grip is too strong.
"+Consoling+ Relax ${name?}," Isrya says
