How common is sex between a brother and sister?

When my BFF told me that she sleeps with her own brother, I thought she was just messing with me. Years later, I still doubted her, then she proved her point. One night her brother and her got drunk, but not completely out of it. They had sex in front of me just to prove her point. I guess it is more common than people think.

In the San Francisco Bay area, where I grew up and still live, there is a lot of it.

I don't have any brothers, but one of my girlfriends that I grew up with is having sex with both of her brothers and another one is having sex with her brother and her dad ...no, I'm not kidding!

It is all consensual so I see nothing wrong with it.

@laurieluvsit I don't either as long as both agree

@laurieluvsit I don’t judge as long as it is consensual and they are happy.

@laurieluvsit As long as everyone involved is happy why not

@laurieluvsit Jesus! Who do you hang out with? I'm from the Bay Area, and have never heard of or seen anything like this in the Bay Area social scene.

@MsJenzz I agree completely - and I'm sure it's more common than most people realize
