Thing is.
Reika used to be the MC's step-sister.
Back in the day, when Quickie was just a series of
flash games.
But to no one's surprise, they eventually turned tail and
fixed that because they're afraid of patreon.
Now she's just a really close childhood friend.
I doubt this game has any traces of that, too much of a risk for them.
So any patches would entail someone rewriting the script to fit that.
No way in hell they make the mother fuckable either.
So the only thing close to incest will be that roleplay scene in the family room.
I really doubt someone will bother to actually go and rewrite the dialogue.
