I have always wanted a pet dog but never wanted to have to clean up behind one or take care of it. So when I decided that it was one of my slaves turn to leave the fold, I decided to have some fun with it. I bought a doggie tail butt plug, a choker collar and a leash. After stripping her naked and making her get on all fours I stuffed the butt plug up her ass, put the choker collar on her and attached the leash. I made her do all the things a dog does, from barking to doing the normal dog tricks, sit, stay, roll over , shake. I took her for a walk and made her shit and piss outside on the lawn in front of the house. To add to her humiliation I made her smell her own shit. When she started gagging and puking it really pissed me off and I began yanking on the leash, choking her with the collar. Each time she gagged and spit up it made me madder and I pulled harder. Her face began to turn red, her lips were becoming blue. I knew I was strangling her with the collar and it began to turn me the fuck on. I kept going pulling the collar harder, holding the pressure longer, over and over again. I could feel my climax building as I watched her being strangled at my hand. The closer I got to climaxing the more intense the yanks became and the longer I cut off her ability to breath. Finally she fell limp and I yanked and held the pressure as my cunt exploded in an intense orgasm. Death by strangulation is something I have done many times but never like this and I loved the new thrill!
