I think that the game will becoming much more engaged if we have less repetitive content. We should not see the same content at the same hour in the same room over and over again. May it be randomized a bit or add alternative content.
For example:
1. I would like to see alternative dialogs between the little sister and her mother in her room. We can definitely add more content there to reveal more details about the life of the mother to prepare for more events in the future. For example, the mother can talk to his daughter about sex and pregnancy. She can tell about how she met the father and how they made babies together, the position they like and how boring it currently is
2. When the mother comes to our MC room, she acts like a slut every time. It is inconsistent and boring. I think that we can add alternative content there, randomize them or it can be event-driven: love talk and sexual touches after our MC refused to punish her in the basement or now her sex desire over the MC grows over (confession)... Dirty/Fifthy talk is really fun.
3. The talk at 9PM everyday is very boring. It is great if we can see more mother-MC touches there even the hidden one. It is really fun to see how our MC and the mother react when that thing happens in front of her husband. Also the gang should discuss about new sex drug, its possible sale and how it impacts sexual activities. They should employ girls to test it as well
