>No tau water caste diplomat who makes contact with a culture of humans who adore fat women and is gradually fattened up over the course of many "diplomatic" banquets
>No all female chaos cult who botches up their demon summoning ritual and get a bizarre Nurgle/Slaanesh demonette hybrid who acts as their voluptuous mommy feeder because she is convinced that morbid obesity is a disease worthy of Papa Nurgle
>No Admech magos biologis who becomes obsessed with discovering the upward limit of human obesity.
>No all-female regiment of guardsmen who get stuck on a pleasure world thanks to a warp storm and find themselves softening thanks to an abundance of delicious food and no threats to deal with
>No starving digga psyker who develops a taste for orkoids, particularly nice juicy squigs, and overtime becomes more and more orky, until she becomes a sexy, strongfat warboss with a massive paunch.
>No phaerakh who glitches out and starts obsessing over regaining the curves she had before being turned into a robo-skeleton causing her to pump herself full of gelatinous necrodermis which she falls in love playing with
>No secret genestealer cult which disguises itself as a combination fertility cult/ high society social club whose members abduct rich, skinny women and feed and fuck them into breeding stock for the cult.
