I knew that my wife had a history when I married her, but I didn't know the details. Recently while doing some cleaning I came across an old homemade video of her with an old boyfriend --- and a very large black lab. The video shows her on her hands and knees letting the dog mount and fuck her while the boyfriend jerks off in her face. She's very clearly into it. I confess that I jerked off while I watched it, but then felt very weird. I've never been into that zoo crap, but now it's all I can think about. Something about watching that great big animal mount my pretty little wife and fuck that sweet pink hole. I wonder if we got a dog would she do it again for me but I'm afraid to ask.
