Masturbating while watching my wife get anal penetration

I've always been a bit of a voyeur, and nothing gets me more turned on than watching my wife get her tight ass penetrated. So, when she brought home a huge-cocked stud for a little extra action, I was in heaven. I set up my camera to capture every moment of the encounter, and as I watched from another room, my cock grew harder and harder. Unable to resist, I started masturbating, my hand moving rhythmically as I watched the sight of my wife's big ass getting pounded by that monster cock. The sound of her moans and the slapping of skin on skin only fueled my desire, and before long, I was lost in the pleasure of my own touch. The sight of my wife being taken doggystyle and bent over only added to the excitement, my hand moving faster and faster as I neared climax. The experience was so intense, so overwhelming, that I knew I had to do it again. And again.
