J’ai filmé mon beau-père en train de défoncer ma copine dans la salle de bain

We have a common bathroom at home and it's easy to notice when someone is taking too long. It was my girlfriend, and she was making funny noises in there. I looked and saw my stepdaddy drilling her doggystyle while she held on to the glass enjoying every inch of his big shaft. I'm yet to tell her what I saw.
