My snout grazes over your moistened diaper. Your cries of ecstasy motivate me to continue on, my whiskers twitching with equal excitement. I open my mouth-- ever so slightly and bite a thicker part of your diaper. The crinkling noises of my fangs lightly pushing up and down on the material drives me wild, my erection getting impossibly larger. When you finally go silent and all either of us can hear is panting, I rip your diaper off. Now you're exposed. I push back my furred foreskin and put the tip into your pulsing anus. When I thrust in, you yip and your tail stiffens. Your asshole is nearly too tight, but like elastic, it stretches open to welcome my ever growing member. I smile at this. I fuck you for almost an hour like this, you pissing all over me the entire time. I finally feel myself begin to cum, slowing down and holding you there. My dog semen drenches the inner walls of your asshole, and I can't stop moaning. In my orgasmic fit of pleasure, my tail twitches and the feces are coming out of me. I realize this about six seconds later, but it's too late. Halfway out now, the slick log of shit plops below me and onto the couch. I relieve the rest of the pressure with a wet, sulfuric fart. Your eyes roll to the back of your head. I pull out of you, and on you is a mix of sweat, semen, and shit. You're beautiful.
