My exs daughter Amy seems to become more comfortable staying with me. Yesterday while her daughters were at school I noticed a car in the driveway that I didn’t recognize. I was in the kitchen getting a drink and started hearing some slapping sounds coming from her room. So I got closing and I could hear some faint moans and the sound of what must have been her ass slapping against someone. So I decided to lean against the wall and enjoy the sounds of her getting fucked. She got to the point where she was calling him daddy and asking him to fuck her harder she even asked him to cum inside her. Her was calling her his little slut and then I heard some grunting and that was my cue to stop listening. I was so glad I got to listen in on that little fuck fest.
