Jen and Claire spit out a pill each and managed to put it in Lucy and Frieda's food, which as soon as they ate they underwent a new change. First their bodies separated, and then they went through different transformations separately.
Lucy went through what would be almost a reset if she wasn't originally a dog, becoming a human girl, but she had dicks instead of nipples on her four breasts and a pussy on her face taking up the space originally intended for her mouth and her nose. She still had her mouth and nose, but now they were in her crotch.
Frieda, on the other hand, underwent a two-step transformation, first completely returning to normal as she was before she transformed for the first time, then a brown fur covered practically all of her body, with the exception of her face, breasts and genitals. Her body then swelled a little with her feet and hands turning into what looked like paws, and her ears got rounder and moved over her head. Her body then assumed a sitting position and fixed itself in this position, making her unable to move. Finally the last visible change was her pussy being inverted into a ballsack while her clit grew into an 11 inch cock. In the end she was a mix of animate and inanimate, as she had become a human-sized teddy bear who had a flesh-and-blood human cock, breasts and face.
When their transformation completed Lucı stood up and before she could do anything they heard a horn. Jen and Claire looked in the direction the horn came from and saw the Van in which they would have gone to the beach in the altered reality standing there, it had the engine running but there was no one inside the vehicle.
"Let's go girls. I know you guys are having fun but it's time to wrap up our tour and head back home." They heard Mrs Watson's voice coming from the Van, indicating that she was the driver.
Lucy took Frieda and went to the Van, Jen and Claire also went there and got into the vehicle.
"You always have your teddy bear aren't you Lucy? Don't you think you're too old for this?" Mrs Watson said
"You would also always carry a teddy bear if you had one like mine." Lucy said
"Speaking like that you offend me, I may be a teddy bear but I have feelings too." Frieda said
"I'm sorry, I just wanted to tease Lucy a little bit." Mrs Watson said
"Speaking of which, I always thought it was weird even with you and your parents being mutants Jen and Claire are normal people. Are you really biological sisters?" Mrs Watson asked
"Yes, they really are my younger sisters. Our parents were surprised when they were born two normal girls and we weren't sure what their lives would be like as part of a mutant family, but it seems that our concern was for nothing. They have adapted very well to life with us, so much so that they also don't wear clothes even though they know that going out in public without clothes is only normal with mutants." Lucy said
"I know, the best thing that could happen to me was that Lucy insisted her parents buy me at my parents' store when I was a kid. They didn't want to sell me but they thought I would be happier in a mutant family than living anywhere among normal people." Frieda said
Jen and Claire looked at each other finding it interesting that one more change made in their family. Now Lucy was no longer their pet dog, but their 1 year older sister, while Frieda was her teddy bear that she carried everywhere.
