I know some women on here who have fantasies they like to be explore and discuss, if they're actually married or in a relationship IRL, I never want to delve too deeply into if I can help it.
A lot of stuff like this place I see as purely escapism. For some women it's known and accepted they're here by their partner, and provided it stays as a internet thing it's fine between them.
Obviously though, like anyone there are strict lines I don't think people cross even in a fantasy setting lol
