Everybody know how it is important to brush your teeths. Not my sis. She would do anything to avoid it. That evening i thought she need some help doing it. I have suspicious that i could not end well since she had that sex dress on her. Also I could smell wet pussy. I just ignored it. When we reached bathroom i realized that sadly i was right. She better fuck than brush teeths. Good thing that she is so good at fucking and her boobs are so great. We will try next time to brush since her smell from mouth is disaster. Hm maybe it comes from her pussy too.
