My wife and her sister give a lot of oral sex, I love taking care of their mouths while they lick my penis.

My beautiful wife invited your sister with us. she asked me if i wanted to fuck her sister and i said yes, my sister-in-law has a big ass. I was just thinking about my cock between her buttocks and my cum in her mouth. no other way of thinking about her, other than my wife wanting to share my dick with her sister, it was her dream.
