Hannah's first and Nina's second sex scenes. Some story progression and a few fun moments. It's probably slightly longer than the last update with around 650ish renders.
I'll share plans for the next update within next few days.
That revelation would be disappointingly obvious. Long lost child is frankly an overused cliche. And it's risky with patreon's policies. They are too anti-incest to allow a threesome where only the girls are related to each other.
MC's mother being the same kind of demon as Katherine is practically guaranteed though, but even so they might not be related in spite of the kind being rare, because logically it shouldn't be.
1. They are highly priced by higher demons, so there should be plenty of protection.
2. The seductive aspect of their power should give them more protection.
3. Girls always inheriting their mother's power should make them relatively numerous.
It's something of a plot-hole. I can think of plausible explanations, but until the game offers one that's just speculation.
