As you ride home in his car your canine mind at first does what any dog would do, you hang your head out the window. This is fun, and you pant as you do it, your Labrador ears flopping around in the wind. Soon though, your experience is cut short by the automatic window being rolled up. You turn inside with a wine and look at your master with begging eyes. He says, "No boy, I don't want too many people noticing I have a new dog just yet. And besides, I've got something else in mind for you to pass the time." You turn your head sideways, not understanding what he means. Soon he unzips his pants and it becomes clear, his 9-inch throbbing cock coming out of his pants to greet you. At this time you get a funny feeling. It's as though there is this old part of you that is revolted by the idea of sucking off some guy's cock. Your doggy mind tries to understand this for a moment, but then forgets about it as soon as he gives you the command "Suck". With that your mind is content, whatever master says goes. So you shift around in your seat to get a good angle, then you lean over and start licking his cock and balls like a good obedient dog. Once his cock is more erect, you take it into your canine muzzle. "Uhhh, good boy." Master says as your head starts bobbing up and down on his cock. This bit of encouragement is all you need. Your Master is happy, and so you are happy. It's the most fulfilling feeling that you could ever imagine, making him happy. And so you become happy. Your tail starts to wag, while your 8-inch red doggy cock starts to emerge from it's sheath. You continue bobbing your head up and down, filling your muzzle with Master's rod and massaging it with your rough canine tongue. Your senses as a dog has been greatly enhanced. You can taste his salty member in your mouth, as well was the faint taste of his pre-cum, a promise of your reward for being such a good dog. You feel every texture of his dick in your mouth, you can tell where his piss-slit is and where his cock flays out. Your simple canine mind can tell that those are the places that give Master the most pleasure, so you give them special attention with your tongue. You can smell thick musk in the air, and on your master's crotch where your canine nose is buried. Some is your own, and some is your Master's. His makes you horny beyond your wildest dreams. Eventually you pull off of his member which seems to be on the verge of exploding. A bit of pre from his cock stretches out in a thin line to your mouth. The taste a sweet promise of things to come. You don't stop long, because you know that wouldn't make Master happy, and that's something you can't risk. So soon your back using your canine muzzle and tongue to give him animalistic oral pleasures, but this time the center of your attention is his balls. They're the size of golf balls, and you can tell they're full of your Master's cum. As you take his balls into your muzzle and begin rolling them around with your tongue the idea of his sweet cum floods your mind and makes you want to climax right there. But you're a good dog, and you don't want to get your Master's seat dirty. He moans from the continued treatment on his big balls, your own balls forming a knot on your doggy cock, wanting release. The smell of musk in the air increases. The car pulls into a driveway, but you barely notice the background because you're so focused on being a good dog and pleasing your master. You think your Master is going to cum soon so you release his balls and go back to gorging yourself on his dick. The car stops, your Master moans because he can now pay more attention to the wonderful cock sucking you are giving him. He keeps moaning, his arms thrown up over his head. "Ohhh, g-g- good, yes, good dog, uhhhh!" His voice makes you suck harder and faster, knowing that you are making your Master happy, and that's the greatest most joyful thing in your doggy mind. Sure enough, he soon grabs the back of your head behind you're yellow-furred lab ears and holds your head in place. This makes you kind of worried, but you know you can trust your Master. He thrusts his cock deep into your muzzle, and pulls your muzzle down on his rod at the same time. Soon your muzzle is full of a hot creamy liquid. Being a good dog you gulp it all down, the taste sweet to your altered doggy mind. "Ahhhh, good boy, drink it all down, that's a good dog." This was more than you could take. As you rose off of his cleaned cock and sat up in your seat you couldn't contain yourself anymore. The smell of musk was so thick you could taste it, or maybe that was your Master's sweet cum. He was so happy, and that made your altered mind even more happy. Unable to hold back, you shot a load of dog cum all over the leather seats of your Master's car. Your teeth showed and your doggy face had an expression of utter pleasure and powerful lust. Ropes of white jizz went all over the seat, and as soon as it was over you looked at your master, panting. His eyes showed disapproval, which was enough to make you regret what you had done. But he didn't scold you at all. "Wow, you are one very hot horny dog. I've never seen anyone shoot a load from giving someone else a BJ. I'll let it slide, but don't make a mess again ok? Now clean it up and come inside." At that your canine ears perked up, you were happy again. You quickly and joyfully lapped up every drop of your own cum, making his seats squeaky clean. The taste was salty in your mouth, and good. As you got out of the car and followed your new Master inside, you noticed he lived in a large farm house, apparently alone. "Come on boy, let's get something to eat." You went into the kitchen and found a bowl of dog food waiting for you. This seemed natural to your altered mind, so you started eating. But there was another side of you that this didn't seem natural to, and that was disgusted about being a gay dog and loving to suck off another guy's cock. And that side was fighting for control.
