I really hope we get a repeat of that mother scene, but with the MC doing more than just tonguing and fingering.
Would be especially hot if it actually rotates between the MC and the dad taking turns, without the dad actually knowing
Like if the dad has to keep taking office calls, MC keeps hiding before the dad comes back, both of them unintentionally not letting the mom orgasm before they both stop in between, until she cries and screams for the MC to get her off, thinking its her husband, and the MC creams in her

Then the mom is too tired to continue once the dad comes back, leaving him the only one unsatisfied and unaware of the son's creampie in his mother
I have big hopes for the kinkiness in this game after that tied up mother scene, hopefully at least some of them are met.
