This was a few years back when my sister in law still lived with her parents, almost every time we would visit, I would go to her bathroom to "take a shit" and then I would go through her dirty laundry basket and pick out her dirty panties and smell them as I jacked off. This is my wife's younger sister. Sometimes I would stuff one pair in my mouth while using another to stroke my dick. I even came in them sometimes, I would bury those in the basket. It was so hot. Unfortunately my wife and her had a falling out and she moved to another state. I sometimes fantasize about her when fucking my wife. I almost called out her sister's name one time during orgasm.
