Couple suggestions so far.
First, the text box interface is a big black box taking up too much space on the screen. My suggestion? Give us controls over the text box opacity, please.
Second, there should be a clear separate button for going back to the main menu. It should not be hidden behind the "Quit" button.
Third, the animations are a bit too simplistic. Kinda like watching this:
Fourth, the "ramping up" stages of the sexual encounters is too obviously formulaic, thus it's boring. Every game has a formula, the trick is to make it fun and exciting and stimulating.
I like that you're tackling the perspectives from two distinct angles - the dad and son. Very ambitious and has possibilities for entertaining worthwhile replay.
Anyway just my two cents, have a good one. Cheers!
