By the time you're ready to cum, the Zoolady has already made you a full dog. Letting out a low whimper, you release your semen into her mouth and throat.
She guzzles it down like water and licks her lips clean. Then she stands up and says, "You're a good boy, my sweet little Teddy. So sweet, in fact, that I'm going to make you my pet for the rest of your life. You what that means, don't you? It means you get to impregnate as many bitches as you want."
And she was serious. The next day, three new bitches were brought in for breeding purposes, and the Zoolady only let you mate with them. The feeling of your penis as it inflated, keeping it from slipping out until you had finished your business, became the best feeling you ever had.
Over time, you become something of the leader of the kennel, with the other dogs giving you great respect and obeying your every lead and command. When you eat, they eat. When you shit, they shit. When a bitch gets horny, you get to go down on her first. You feel empowered as an alpha.
But the best part of all is that when most of the other males are taken away to have their balls removed, the Zoolady lets you keep yours. How humiliating is must be for those poor dogs, condemned to wander around with pockets of loose skin under their penises, never able to reproduce or ejaculate ever again. Thank God you're not one of them.
Eventually, many years later, you find the Zoolady is getting ready to find a new alpha, as you are becoming too sick and old to be of much use. She calls in the vet to put you down with an injection.
Your funeral is attended by all the other dogs, as well as the Zoolady and the vet. Your body is cremated, and the ashes are buried under the kennel, so that your spirit may watch over the dogs for all eternity.
