Yah I agree with you. Aside from Melissa the rest are getting or are already kind of ruined because of the HARD force scene or 180 flip in their characters. Honestly I think I can write a better story than Shamantr. I just don' know jack about animation and game making. But check out my revise.
Camila the most important one is a easy fix.
Cheating route is fine up to the third act. But change the last act entirely or refine it. Give Camila a oh its just the tip or at least vagina rubbing scene in end of chapter one. Its already heading there. Then by chapter two they bang. Easy.
The cuckold route will just follow some of the Red room idea. During the first act, when Camila shows up to school late, she tells Fred she wants him to be the lifeguard like already in the story. Fred decides to go with Camila to try out. Teacher Ella asks Fred to demonstrate but he is mediocre at it. Ella rejects Fred and Camilla is sadden by this. However Jason uses opportunity to get close to Camila, and convince teacher Ella to that he will teach Fred as a back up lifeguard. This ways we get Fred, Camila and Jason a reason to be in the same place. Ella accepts because she likes Jason. By now were in the mid first act. Camila excited from the idea that Fred can become a life guard, jumps in pool to congratulate Fred. But she forgets that she is still fatigue from her morning sickness, Camila struggles and almost drown as Fred panic helplessly. Jason swoops in and saves Camila, full body contact, arms wrap around each other, her legs wraps around Jason waist as he lifts her outta of the pool. Camila blushes. Fred watches all of this with a hard on.
By evening and the end of the first act Fred, Camila and Jason ask teacher Ella to practice swimming after school to get Fred up to speed. Ella accepts but won't supervise. At the swimming pool Fred determine to save Camila in the future, swim vigorously. Jason outside of the pool flirts with Camila and gets in her ear about cuckold and BBC. Fred seeing them conversate jealously swims even harder and drowns. Jason jumps and saves him, but Fred is unconscious. Here the dream sequence begins but is strictly Camila and Jason related. While this is going on, Jason refuse to give Fred mouth to mouth but will teach Camila how to using her own mouth as an example. Camila rejects it, but gives in out of desperation. So they mouth to mouth and it turns into a passionate kiss instead. It at this moment Fred wakes and catches them. Camila pushes Jason away and explain herself, but they both notice Fred has a hard on.
Honestly I would write more but I don't want to be wasting your time lol. So that the kind of the idea I would of went with. And don't even get me started with Blackmail.
