Di knew her family's changes wouldn't begin until tomorrow, so she decided to head out and try her new powers.
She walked out her front door, leaving her foster family behind to go about their normal day. She enjoyed the clicking of her heels as she walked and the flowy feeling of her skirt around her legs.
As Di headed down the street and saw her neighbors, the Winstons, doing yard work in front of their house. John and Margie Winston were a retired couple who lived peacefully with their beloved dog, Rover. Di always thought that John never paid enough attention to Barbara, instead preferring to spend his time with the dog.
Di walked up to the fence. "Hello, Di!" said Margie. "How are you doing today?"
"Very good," said Di. "I actually have a surprise for you guys."
"Oh, and what could that be?" Margie asked.
"Well," said Di, "your family is going to be rearranged a bit. John now believes he is a dog. He will act like a dog, walk on all fours, bark, pant, sniff everything, wear nothing, and poop and pee outside. Even though he still is a human, he will act 100% like a dog. Rover will become an anthropomorphic dog. He will stand up and walk on two feet and he will look and act like a human, except with a dogs head, fur, and tail. He will even be able to talk. Rover will have a large 10 inch cock that he loves to show off. Rover and John, despite being different species, are in a romantic relationship. Rover will love to fuck John's ass, and John will love to suck Rover's dick. Margie your age will regress until you are 16 years old. "
Di continued: "You will be in high school again. Your parents are Rover and John, who have been happily enjoying their gay relationship for as long as you've known. No one will question that they are your parents or think their relationship is unusual. Nobody will question Rover's doglike name and appearance and will treat him normally. Rover will work as a mid-level employee in the corporate world. Margie you hope that one day an anthropomorphic dog woman will be your lover and you can live your life as a dog like your dad. You hope to have the same kind of loving, lasting relationship that your parents enjoy. You've also already begun showing some minor doglike behavior, and will continue to act more like a dog as you grow older."
"These changes will take effect now and no one will think that there is anything wrong, though people do recognize the unusual nature of your family."
As Di said it, the changes took effect. Margie regressed in age before her eyes until she was a cute 16 year old brunette. John immediately removed all of his clothes and dropped to his hands and knees. He began sniffing at things around the yard. Rover turned into an anthropomorphic dog and clothes appeared on him: a white floral Hawaiian shirt and khaki shorts. The shorts were wide open in front and Rover's massive cock hung out, swaying as he moved.
"How's that for a surprise?" Di asked Margie.
"What's surprising, Di?" said Margie. "Everything seems normal to me."
"Oh, you're right," Di replied.
Rover stood up from his gardening and came over to Di and Margie.
"Margie, have you greeted Di properly?" Rover asked.
"Oh, right!" Margie responded. She walked around Di and crouched. She stuck her head under Di's skirt and sniffed her asshole. Then Margie came up and back around and licked Di's face a couple times.
"Very good, Margie! You're a good girl!" said Rover enthusiastically. Margie shook her butt back and forth in response. "Margie's going to be a very good girl when she grows up," Rover said to Di. "Her sense of smell is already improving, and she's begun to eat proper dog food. And Margie, for being such a good girl you get bacon tonight!" Margie couldn't contain herself and wagged her butt even more, and barked a few times.
"Thanks for stopping by, Di!" said Margie. I've got to go eat dinner.
Suddenly the large cock hanging between Rover's legs grew stiff and erect. "Wow, is it that time, already?" Rover wondered aloud. He whistled, and John immediately perked up from across the yard and looked right at Rover. John began to cross the yard, but when he was halfway across he stopped. He squatted in the grass and pooped right onto the lawn. Then John ran over to Rover, jumped up with his hands on Rover's shoulders, and licked Rover's face. "Down, boy," said Rover. "It's time for some fun! Turn around boy!" John happily dropped to all fours and turned to face away from Rover, sticking his backside into the air. Rover quickly plunged his oversized cock into John's asshole, and John yipped. Rover fucked John's ass ferociously, and John shook his butt back and forth furiously, only adding to their pleasure.
Di watched the scene for a few moments, feeling dampness between her legs. Then she turned to leave, saying "See you later, Rover!"
Rover grunted as he continued to fuck John. "Anytime Di. If you see any female dog anthropomorphs, put in a good word for Margie; she's been looking."
"Certainly," Di responded, then headed off down the road for some more fun.
