It started as a joke, a fun game of truth or dare with my girlfriend and her best friend. As the drinks disappeared, so did their inhibitions. When I dared them to let my horny Doberman, Rusty, fuck them both, they actually agreed to try it - to my utter shock and delight. I never thought I would get to watch the two hottest girls I know try out bestiality right in my own living room. It was a night that I will never forget, and I don't have to, since I videotaped the whole scene.
