I have the following issue. If i complete the "being usefull" quest, i am not able to pick the option of "Cockold porn" when masturbating in order to unlock the cockold content. On the other hand if i open the cockold event firs, i cannot complete the being usefull quest even if i have completed all the previous quest of "pussy worship" content. In that case every time i watch tv with Zoe lying naked on the couch she only asks for feet rub. I also face some more issues. Sometimes Zoe appears without painted nails and with her starting clothes. She also appears the same in every pegging scene and every time she is waiting on the bed.
Also while I am here I would love to give a few suggestions.
1. more feet worship content especially with feet licking. You can also add it as a punishment or humiliation when the MC is not able to satisfy Zoe while having sex or in other cases like the "being usefull" quest in order to satisfy Zoe while she performes other activities like using her phone or reading a book or maybe something like that or something else that you have in mind.
2. More pegging scenes. You can also add them as punishment.
3. If possible you can add a chain with the chastity cage key aroung her neck or with an anklet.
4. In addition to favor you can also add the possibility that when the MC asks Zoe to unlock him, she demands certain services before unlocking him.
5. Dialogs with more SPH.
I hope i am being helpfull.
