User:Cum Girl
I'm the author of Free Use Universe, a linear narrative about a boy who falls into a very lewd world, where free, happy, casual sex between people of all ages and genders is common. In the future I may open it up to a wider hub for free use content in this setting.
I also created Naked in School and Sexual Research Commission to expand those genres of story, but outside ASSTR (where account signups are broken).
I also contribute to Brave Nude World.
