three months isn't too late to respond to an ask right. this is definitely normal. everyone continue reading as if it hasn't been ages since I've posted a retrospring answer….

firstly! dee if you're reading this, i miss you and i hope you're doing well o7 i hope to see you back around again soon!

but yeah, i absolutely think a good handful of those girls have an incest kink. sayo is a given—if she and hina aren't incestuous with each other, her sister complex carries into every other relationship she’d have. sayo would secretly fantasize about being able to take care of her partners like they're a helpless little sister, and would revel in the thought of someone being completely dependent on her. since hina could do anything she wanted without sayo’s help, isn't it nice to pretend she's needed in that way?

hina probably wouldn't have much of a siscon kink outside of sayo herself, though. roleplay and fantasy couldn't match the real thing! she might have a thing for mother/daughter roleplay, but being a sister is a reserved role…

i think tomoe also has a huge incest kink as a result of suppressing her feelings about ako. she knows that trying to do anything with her would be so painful, she'd never get over the guilt, so she has to satisfy it in other ways. she's definitely ashamed to mention it, but if someone dragged it out of her, she would indulge.

and as a quick list for the rest, other girls who would have a mother/daughter incest kink are— saaya, chisato, rinko, ako, lisa, taki, soyo, nyamu

and for sibling incest…. rimi, ran, himari, ako, taki, raana, mutsumi.
