After rubbing John' belly, Deborah let him and Kate run off with Harry, the three of them yapping excitedly as they played tug of war and stole toys from each other. Deborah in particular was only partially listening to her friend Rebecca talk about her day, instead, Deborah was realizing how weird humans looked with tails, and quickly removed them with her newfound powers. She also shortened their legs to be the a little longer than their arms, making them more comfortable as quadrupeds, but still with their butts up in the air.
Finally turning to her friend Rebecca, Deborah started enjoying her new role as the progenitor (and citizen) of the dog world.
John and Kate meanwhile had stopped chasing each other, laying down under a tree at the human park, they panted and smiled, blissfully unaware of what was stolen from them by Deborah. As Kate laid on her back, her breasts sprawled on either side of her chest, John was getting excited, for you see, Kate was in season. Walking on all fours over to her, he eagerly began sniffing at her crotch, occasionally licking it to get her interested before she got the hint and got on all fours and let herself get mounted.
In full view of the park, John and Kate were going it doggy style, or human style in this new world, without a care as to who was watching them. Deborah laughed at the sight, she'd just mentioned that she wanted to breed them, and now she had her wish!
After only twenty seconds, John climaxed, and the act of human mating ended. As john went over to pee on a nearby tree, Kate happily trotted back to Deborah and started nudging her owners hand, begging for treats. But Deborah shooed her away, wanting to talk to Rebecca a bit longer, Kate simply went back to the tree, but not before squatting and dropping a massive pile of poop on her way, causing Deborah to groan as she grabbed a slightly larger bag to clean up her humans mess.
"I certainly hope you get knocked up Kate." She said as she approached the pile of poop, "Otherwise this'll just get boring."
Kate merely sat there panting happily as she was nuzzled by John under the tree.
