When I use to sleep at my friends house in the middle of the night his bulldog would visit me and jump on the couch straddling me as I lay on my back. I'd grab his dick and jack him off all over me. It was so hot because he tried to fuck the shit out of me. He sprayed more cum than any other dog I've ever jacked off. I was practically soaked when he was finished. When he finally stopped thrusting at me violently his dick would be rock hard and bob up and down as he sprayed more and more hot cum all over me. I loved the feeling of cum hitting the back of my throat when I deep throated his big dick. It was intensely arousing because my friend could walk into the living room at any time or even hear me talk dirty to the dog while he clenched me and took me for a ride!
