Will there be a 11.7 where zurikishi introduces the mom or will it jump straight to chapter 12 where the sister tries to NTR and got caught? Place your bets!
Damn, little sister ain't so little. I also like how they all have moles on different parts of theír bodies. If the author's gonna blueball us with the yandere anticipation, I could think of worse things than introducing us to the fam.
