Respectfully disagreeing on putting female sexed, non binary content in with the male content, I don’t think how you identify you gender is relevant here.

maybe have the girls legs tied up in splits and have her sit with her pussy on a huge plug for as long as she can

I second this. I would love to see action/adventure games RPG. Where your created character girl goes around getting her holes all fucked up but big objects or monsters. Start off with tiny holes and leave with massive gaping ones
