Benjamin smiled evilly as he typed in Johnathan's new perimeters.
He changed his brother's species to domestic dog. He set it up so that his brother would change in body and mind over the next 72 hours. He would have urges to act like a dog, and his transformation would accelerate whenever he gave in to those urges.
While Benjamin and Jonathan would be aware, Benjamin changed the awareness and the reality settings so that everyone else would think Jonathan was his dog.
Benjamin gave Jonathan some canine characteristics and removed his ability to wear or use clothes, before finalizing the changes.
A moment after hitting enter, he heard his brother yelling.
"What the hell?!" Benjamin headed to his Jonathan's room to see his naked brother sitting on a dog bed on the floor. Jonathan was feeling his new dog ears with his hands, which now had dark pointed nails. A tail stuck out behind him. Jon let out a sharp yelp as he looked up at Benjamin. "B-benji!" Benjamin saw Jon's sharp canines as he spoke.
"What the heck?" Said Benjamin, feigning surprise. "What happened to you? What happened to your room?"
"I... I don't know. I was just sitting here when when everything disappeared, and I had a a dog tail and ears!"
"C-can I feel your ears?" asked Benjamin. Jonathan pulled a face, but he kind of liked the idea. He nodded 'yes' to his brother, who walked over and began to rub them.
Jonathan's eye's closed his eyes as Benjamin began to scratch behind his ears. Benjamin watched his brother began to pant. Johnathan's leg thumped the ground as his tail wagged.
"That...feels great man...keep scratching..." As Jonathan enjoyed his scratching, his black nails thickened and curved, becoming true claws. His chest, normally hairless, grew a light layer of fur. Jon laid down on his back as he looked up at Benjamin and whined. "...Belly ...scratch...belly..." Benjamin reached down scratched his brother's stomach. He stopped and pulled back his hand when he saw his brother's now canine dick emerging from its sheath. Ben looked at his brother.
"Um... Jonathan?" Jonathan panted happily for bit, his tongue lolling out of his mouth, before he came to his senses.
"W-what am I..." Jonathan looked at his new claws and fuzzy chest. "Why'd you scratch me?"
"I-I don't know." lied Benjamin "You just acted like a dog, and I thought you were a dog for a moment" Jonathan looked at his body as he pondered his predicament.
"Does that mean I change whenever I act like dog? If I don't act like one, will I change back?"
"Maybe?" Said Benjamin.
"You won't change back unless I want you too." Thought Benjamin. "You'll give in and be my loyal doggy!"
"Benjamin, dinner!" called their mother from downstairs.
"Okay mom!" replied Benjamin.
"Great!" groaned Jonathan "I can't go out there naked!"
"I'll lend you some of my clothes." Said Benjamin.
Benjamin got his brother some of his clothes and watched as Jonathan fumbled with them. Jonathan panicked
"How... do I...? I don't know how to get them on! How do I put them on?!"
"Benjamin! Bring Jonathan down with you he needs to eat!" called their mother.
"I can't!" said Jonathan.
"Maybe mom can help?" said Benjamin.
"Yeah... maybe." Jonathan got up and followed Benjamin to the dining room. He breathed his brother scent in deeply as they entered the dining room. "Here we go." thought Jonathan.
Jonathan walked out from behind his brother and looked at his mother.
"Mom? Don't freak out-"
"Oh Jon, how's our little puppy?" Jonathan was shocked and terrified.
"Wha?"
"Are you hungry? Your dinner's right over there." Jon turned to the kitchen to see a dog bowl sitting on the ground, with his name on it. the bowl was filled with a meat and gravy mixture that made Jonathan's stomach growl.
"C-crap" thought Jonathan. "I can't eat that! I'll change more!"
Jon could feel the urge to eat growing inside him. "I can't do it! I don't want it! I shouldn't!" Ben watched his brother fighting his canine half.
"I wonder if he'll hold out?" thought Benjamin.
