I did play with the idea of that. However, if I were to give that option, I'd basically have to make the game twice. Once where MC is dom and Petal is sub, and again where MC is sub and Petal is dom. And while that might not sound so bad because there's only Petal in the game, it would make certain plot elements later not work. This is going to lean more into femdom as Petal will be the one moving the sexual content forward. But there will be optional content where she pushes MC to be the dom as when she asked him to reenact the sexual interaction she witnessed between him and her mother.
This is sort of experimental for me. I'm not sure if enough people are going to want a femdom game like this so it may flop. But I enjoy making it so it's worth it either way. I'll try to take polls to find out what kinks are the most popular and try to feature those more elaborately.
