"Alright Lina," Amy said. "I just need to get a few things before we go."
"Like what? A flea collar?" Lina said half joking but still angry.
"No, silly. Meow. I need a new bra and some new clothes. These clothes are too tight and my old bra broke. Besides, it didn't have enough cups for these." She briefly stroked her lower breasts. "Now come with me. I need you to help me pick some stuff out since I'm color blind now."
Lina picks out an outfit for Amy. Amy leads Lina over to the chair and sits her down in it. "Now wait here for me to get back," Amy says before entering the changing room. Lina reads the instructions on the chair while she waits for Amy to get back. Her crotch starts feeling moist at the thought of what had happened to Amy. She kept thinking of putting a quarter in and getting a tail of her own. Lina could almost feel it.
"So what do you think?" Amy said, snapping Lina out of her daydream. Amy could smell something coming from her friend. It smelled sweet and sweaty like someone had just had sex right in front of her. She knew her friend was aroused. Carefully, she snuck a coin into the meter then placed her hand on the lever for the chair.
"Aww. You look cute. Now can you just get that stuff and find out if there is a way you can change back?" Lina said trying to get her mind off her daydream.
"You know that I picked to be a cat, don't you? If you were going to change yourself what would you have picked?"
"I wouldn't change myself, Amy. I like being human."
"Oh come on, I'm just curious. It is in my kitty nature now. So just tell me what you would make yourself."
"Well...." Lina said thinking. "....I guess I would make a cute dog."
"Dog," Amy said and pushed the lever down.
"Amy! What did you do?!" Lina felt something grab her from behind and pinch her. She tried to squirm out of the chair but it held her down. "Amy, help me," she pleaded through teary eyes. She tried to get up again and this time succeeded. Lina fell to the floor. She dried her eyes and slowly stood. "Why did you do that? It really hurt." She hadn't yet noticed her new appendage.
"Lina. You're welcome."
"Welcome for what?"
"For this," Amy said grabbing Lina's newly created tail.
Lina looked over her shoulder. "OH MY GOD! I HAVE A TAIL!" She just stood staring at the long blonde tail that now hung out from her jeans. She finally reached out and grabbed ahold of it and felt the soft fur that covered it. Her arousal started to grow again and she looked at Amy lustfully. "Thank you."
"I'm sorry that I had to do it like that but I knew that was the only way that you would go through with a change of her own. I knew I needed to share the best thing that has ever happened to me with my best friend. So are you...."
Lina interrupted Amy by giving her a lingering kiss on the muzzle while also probing her friend's new mouth with her tongue. They broke after a few seconds.
"Show me how to become like you," Lina said to Amy. They walked off arm and arm towards the hair dryers.
