First of all. Thanks for clarifying about the tertiary sites, although it's a shame and I won't be able to save more, so it will be a speedrun XD.
And what I wanted to say is that I have an idea or proposal and then you tell me what you think. Once in a section where we have already unlocked the entire path of Amy and Lily, we can unlock the blowjob scene on the beach. (They do it to us on the beach, on the weekend) And instead of having to choose who gives us the blowjob, (Amy or Lily) we can put a threesome scene instead of the blowjob, making it one of the first. scenes that we can unlock of group sex and also that the threesome dynamic can be done but outside of school.
For that it would be mandatory that the desire be 100% and it would also be moving that scene shown in the Amy and Lily section and moving on to the group sex section.
That would be all, I just wanted to give my little idea and I hope it helps you or inspires you for a future idea. Thanks for your time.
