Sibling Relations

My wife is not only the oldest but the slenderest of the three sisters. I got into dating her when we were so young that her sisters and I developed a rather fraternal relationship. Nowadays, either when we visit them or when they come to our place, we don't mind hanging out in underwear or changing clothes in front of one another. I'm sure there's a bit of sexual pleasure on us all when getting to see each other barely dressed, but we just pretend it's a normal thing among siblings.
