Does anyone know how to get any of the endings? I have all the sex scenes with each girl and completed each of their stories but when I try to pick a ending on a Sunday I get "conditions not met".
I've checked your save file. You need to have sex with Ayano at the church. First, she needs to be in heat and visit the church on a Wednesday or Thursday. You will unlock the Doggy position. Later, you will be able to complete the story.
