Incest

Your family always happen to be really comfortable with their body, they often walk around the house naked or do normal activities naked or while doing naughty stuff, my mother often get fucked by my brother while she cook the dinner, i don't find it really problematic and our family have adopted a really great chemistry. You come home from school and see your mother and your sister Julie playing a video game in the room while wearing bra and panties. mother: julie you cant beat me in this game hehe

sister: we'll see mom.
