I came home from a long shift and could hear my daughter moaning and grunting from my bedroom . I walked to the room but from the hallway I could see her on top of her man and it was not her boyfriend. All I could see was her big tits and her riding him , then she caught me and just looked at me. I backed away and we only brought up the topic once but now when she is here , she is more open and flirts abit now. Makes me hard when I think of that afternoon.
