I was just looking on an amaruer porn site when I found a video of a young British couple making their first porn movie. As I watched, I quickly recognised the girl as one of my son's ex girlfriends who was particularly hot. I didn't recognise the guy that was fucking her brains out, but I couldn't help watching her being completely and sluttishly fucked senseless, her head, tits and body shaking to his strokes, imagining it was me filling up her slutty tight bald pussy, my cum dripping down her pert bum.
