Adam/Marie followed Amy down to the TV room, where they found Alyson chatting with her friend, Jenna Worth. Jenna was a moderately attractive blonde, someone Adam might have liked if it were not for the fact that he found her profoundly annoying.
They looked up as Adam/Marie and his/her mistress came in.
"What the heck?", said Alyson. "Amy, who's this?"
"This is Marie, my new maid", said Amy, cheerfully. "She used to be our brother, Adam. I've decided I need a butler, too, and I've decided that you're gonna be it."
"What the heck are you - EEP!" Alyson shrieked as her clothing disappeared. Adam/Marie watched, fascinated, as Alyson's body began to change. Her breasts sank back into her chest, and the other feminine curves of her torso vanished. She grew nearly a foot, as her body became that of a tall, slim, fit young man. Adam/Marie gulped and Jenna yelped as male "equipment" dropped down from inside her lower abdomen. Her face changed last, becoming austere but handsome. Her hair turned black, losing the ponytail, and shrinking several inches. A stereotypical "butler" outfit appeared on her body.
Adam/Marie gaped in awe. Marie looked like a sexualized female version of Adam, but Alyson now looked a bit like Sebastian Michaelis, and she (he?) was HOT! Adam/Marie was on the verge of drooling, until the "Adam" side of him suddenly realized that he (she?) was getting hot and bothered over his own sister!
Alyson stood stock still, looking stunned.
"I think I'll call you 'Frederick"", said Amy.
"Very good, Mistress", said Alyson/Frederick, in the voice of an educated Englishman.
Amy turned to Jenna, and said, "Now, as for you..."
Jenna looked panicky, and said. "I...um...hah.."
"I've always wanted a dog", said Amy, "But Mom and Dad would never get one."
Jenna's clothes disappeared, leaving her naked, except for a dog collar with ID tags on it. She opened her protest, but instead began barking.
She dropped to all fours, as her legs assumed a canine configuration, and her hands and feet became paws. A tail projected from her backside, and dark brown fur sprouted all over her body. Her ears grew pointed, and her nose and mouth merged into a canine snout. Jenna was now a beautiful German shepherd. She trotted over to her new mistress and began licking her hand.
"Who's a good girl?", said Amy, patting her new pet on the head.
She smiled at Adam/Marie and Alyson/Frederick, and said, "Now, then..."
