Inside a small drawer labeled "Augmentation," Jess found vials that had nothing to do with animals or ages. There were shrinking, growth, and gender vials, as well as one labeled "Pet." The brief description in fine print simply said it would tame whoever drank it.
"Okay, you win." Jess handed Mary the vial. "Drink it quickly before I change my mind."
"Mrrrow!" Mary smiled thankfully. She didn't bother to look at the label and gulped the entire vial. Jess took the empty vial back and watched Mary closely for any changes.
"Mrrr I don't feel any different," she complained. She put her hands to her flat chest, expecting breasts to grow any second. Instead she felt an itching around her neck.
Jess could see a ring around her neck where her fur was darkening. It actually looked like the fur there was melting into some kind of black ooze. It finally solidified into a black leather collar with a gold oval tag. Jess got closer to find the tag had Mary's name on it, and described Jess as her owner.
Mary pulled on the collar with one orange paw. "I can't get it off!" she hissed. Jess examined it all the way around and discovered it had no buckle or clasp. It was one unified ring of leather.
"Mary, stop fussing with it. There's no way to take it off," Jess explained. She was a little worried about what this would mean for the two of them. What if they'd never get it off of Mary? Would she have to wear a collar for the rest of her life, even if she was changed back to normal?
Jess was surprised to see Mary obey her. She immediately stopped tugging the collar and stared expectantly at Jess. "Um...Mary, could you sit down over on the bed?" Mary obliged. "Now do a hand-stand."
"Why?" Mary answered.
"Never mind," Jess said. She was glad Mary wasn't a completely mindless drone, but would still do most of the things she was told if asked. The situation made her very uncomfortable, even if she was giddy about their new relationship on the inside. At least she'd get to feel what it's like to have a child and a pet at the same time, for a little while. She fully intended to change Mary back eventually.
"So, what do you want to do now?" Jess asked her new pet.
