Two weeks later:
Kibbles tail wagged frequently as the M squad took her down the line of captured escapees. She looked up at all the grey humans and wondered which would try to satisfy her heat... she wanted something, anything inside to fill the void. One man in the line buckled to his knees and begged to fuck Kibbles.
Espinoza smiled... "you want to fuck my pet? Why your such an animal... so barbaric but surely if you cant resist. Kibbles wont mind she is always in heat".
Kibbles happy to be off here master leash ran over and bent her fore paws so the man could see her swollen hot pussy. The smell hit him as her ass swung around and though the other men were also aroused by the smell they were shocked to see the man pull out his cock and put it into the damn dog.
Kibbles tongue lolled out and she let out something between a bark and yip as he pushed in. She was going to cum she knew it... he was too she felt the pulsing already. Different from doggy cocks in the training kennel but still. He came inside of her and she came around him letting her heat wrap around his shriveling cock (that was the worst part, never remaining full) and soon her heat smeared his new brown hair covered pussy as he began to change into another bitch just like her. Arnold having just enough to remember after Kibbles brief relief knew he was already pregnant with one of the guard dogs pups.... he had no control over the heat... even now he... kibbles wanted another dick inside of her... him. He would have shrugged if he could of and simply picked up his leash into his maw and carried it back to Espinoza so she could take him back on leash as Kibbles was trained.
