Warhammer 40K (XWG/Deathfeederism) Xenos Experimentation part 2 by m00nliner

Overseer Borek Fal’s personal journal, entry one hundred sixty two dash one.
Magos Prax is not the most pleasant person to work with. Arrogant, self-absorbed, always treating people like tools, never even pretending to make any distinction for rank and file.
Just like every other coghead I had a misfortune to be accompanied with.
Still, I can’t help but commend her devotion to this entire affair, as well as the sheer amount of skill, thought and effort she puts into her work. Containment procedures, holding cells, lab sets, data archives, supply chains, fail-safes, cover-up projects and other things great and small, all methodically calculated, ruthlessly implemented and permanently optimized for maximum efficiency.
Fortunately enough, Magos is as straightforward as it gets for their kin. For now.
First batch of test subjects has arrived safely. Four Tau females of reproductive age, each one corresponding to a single sub-species xenologists generally refer to as “Castes”. All transported to the testing area with minimal trouble. Emperor be praised, the Rogue Trader I hired for this job decided not to push our sheer luck with obtaining a member of Ethereal Caste – Tau Navy, as much of a laughing stock it may be, would have certainly went above and beyond the call of duty in bringing one of their “ruling elite” back to the fold.
Quite predictably, Ynessa was quite displeased… she’d have to deal with it. We can’t afford stationing a fleet in this system or building a full-blown anti-ship defense grid on the surface, for it would certainly drag too much unwanted attention to this place.
After considering our options, we have decided to begin this project with a member of Water Caste. Sufficiently studied. Proven to be docile enough. Easy pick. What happened next was fairly surprising – the blue-skinned xeno requested to parley. Naturally, I’d laugh at the prospect of parleying with the foul xeno before turning it down… if it wasn’t for the fact that her demands were voiced in nigh-perfect High Gothic. We agreed do play along, see what happens – after all, what was there to lose? Even more surprising, however, was that upon realization of our intentions... the xeno decided to cooperate.
“If it is a sacrifice required for the betterment of your understanding of our species, the Greater Good commands that it is a sacrifice I must make.”
For a time being, I have naturally suspected that there must be some kind of ploy, some kind of hidden intent. Her actions, however, proved my suspicions utterly inaccurate. With all the things I had to witness in the service to the Throne, it is still well beyond my understanding how brainwashed and how naive one must be to willingly partake in their own inevitable demise.
A mind truly alien indeed.
In the months that followed, the xeno gorged herself on every item of nourishment provided with enthusiasm I had a misfortune to observe only in reports describing activities of the most debauched cults of a certain Ruinous Power. For all my life, I have been attracted to larger women, and as shameful as it is admit, I found observing the gradual changes in xeno’s physique oddly alluring, if not more. Watching Magos poke, prod, grope and otherwise physically interact with the yielding, soft, feminine blue rolls during bi-weekly check-ups almost made my body betray my desires – more than once at that. I even saved some of the recordings on my private data-slate – sinful intents aside, there is a market for obscenities like this in the Imperium, so it may either earn us a decent sum of money or prove invaluable in honey-potting certain people of higher standing later on.
One thing that I have noted during observations was that excess flesh spread across xeno’s body almost evenly – or, dare I say it, almost perfectly. It was a pattern rarely observed with humans – yet here, it somewhat persisted even after the xeno was reduced to a helpless immobile blob barely capable of wriggling her toes. Xeno’s skin also retained a surprising amount of tension and smoothness – where human form would stretch, droop and sag under the unbearable load, her swelling rolls successfully kept their bubbly perkiness, as well as more or less defined round shape until the xeno’s demise. Same could be said about xeno’s breasts – even as the blue orbs surpassed her head in size, they sternly refused to deflate and drop down by her sides, taut skin maintaining their strange oversized appeal.
It didn’t take much for her to become “conventionally” obese – that is, to blow past three hundred pounds. In a way, it could be considered a feat – a feat of reckless gluttony, since it took her less than half a year to achieve, with minimal assistance on our behalf. Then, at about five hundred, she began having trouble moving her bulk by her own power – hardly surprising, considering that “average” Tau has less muscle than average human, and Water Caste members are considered somewhat weak even by Tau standards. Due to xeno’s sheer zeal and dedication to literally eating herself to death, Ynessa didn’t introduce the feeding devices she constructed until much later – at that point, at about seven hundred and fifty pounds of opulent blue flesh, the xeno herself was way beyond immobility, and was beginning to have serious issues with moving her bloated arms around. With Magos’ machine assistance, the xeno managed to reach eight hundred and forty three pounds before her heart began to show obvious signs of imminent failure. There was a debate whether we should put her on life support just to see how far her body can go in terms of accumulating adipose, but Magos ultimately decided against. Thus, at eight hundred and fifty one pound, in just under a year since delivery, the xeno met her demise, her last words being “for the Greater Good”.
Did we get anything out of this? Hardly. As far as I could decipher Ynessa’s techno-babble, Tau accumulate adipose approximately in the same ways we humans do, with approximately same health complications and at otherwise approximately same parameters. She did, however, state that the way this particular specimen distributed adipose was not random, and that she had begun to sequence the xeno’s genes to find the parts that make the biochemistry of said distribution possible. With that in mind, she hopes to synthesize the chemicals that will allow the living batteries to maintain more or less stable shape during recharge.
As for me? Wear the damned respirator when interacting with xenos. Took me more than a couple of shots of de-tox to get rid of all the pheromones I accidentally breathed in. Not to mention the shameful displays of deranged xenophilia in my office restroom.
I pray the Emperor forgives me one day.
