While lion John slept on the kitchen floor, Mary found that she had no meat in the house, so she took some of the human vial to revert to her normal body so that she could go grocery shopping.
Mary arrived at the basic plan that she would stock up on red meat and when she got back, use her hidden lion/femme mix to go back to being a sexy hybrid lioness, and have some more fun being fucked by lion John and hanging out and eating and sleeping. Maybe they could go out on the town again, even.
However, Mary was arrested coming out of the grocery store. Cameras at the bar had identified her car, and she was a suspect in the mauling death of the man who had hit on her, and whom lion John had killed.
The police questioned her all day, but she knew not to say much of anything, and she didn't match the description of her recent lioness-human form. Mary was released, but many hours had passed, and she was worried about John. What if, say the mailman, saw a lion in the house, and heard about the mauling by a lion like creature at the bar?
Mary got home to find that John was not in the kitchen. She looked around her apartment, and then heard moans and soft growls coming from her bedroom.
She cautiously entered, to the sight of an incredibly hot, four breasted woman with the ears, nose, tail, and claws of a lioness, furiously masturbating on her bed.
The lioness girl looked up at her, and said, "oh my God, Mary, I'm sorry, I was tryingto sniff around for a potion to make me human again, but I found some kind of lioness-woman vial you hid instead!"
"John!?" Mary gasped, as she walked over to the bed, and ran her hand down the lioness-girl's lightly fur covered thigh, teasingly close to her cleft ... "You don't need to be sorry ..."
