What are your favorite types of JAV stories or setups?

One of my favorites is the "getting seduced by the girlfriend's sister" setup. Mostly because it allows the performer to really flex their seduction skills. It serves as a true test to any actress.

I prefer ones that seem simple and realistic, like a lady next door or your coworker. There's also always a soft spot for teacher because we all had that one hot teacher. And my number one is cheating with your girlfriend's sister, particularly when they get caught.
