Free Use Sex World

(This is a world where there are no laws that limit sex, everything is allowed, sex in public, at work, in high school, incest, taboos, etc. There is no age limit, sex can be had at any age. And since that's how the people of the world were used to it and they used it freely - for example you can study at school and the teacher is teaching and something fucks the teacher but she continues to teach as if nothing is happening and also in every thing or action that a person does.)
