I just really love writing big women
Kallie is a half-giant, Sikka is a bigass snake, Lilith can look however she wants but her usual demon form is big enough that her horns scrape the ceiling
it's just really cool when women are big
if you ask me which of them is the biggest it could really go in any direction. Lilith is cheating by being a shapeshifter, Sikka is the longest on account of several metres of tail, Kallie is more built than either of them but is arguably the short one if you're counting snake tail length as height.
All of them are huge lesbians also hung.
and it goes without saying that i love giving big women tiny wives to dote on
