After seeing how well the ring keeps Elizabeth from noticing the changes you make to her, you decide to stop with the small changes and go all he way. 'I wish Liz's clothes would disappear again. I wish that she would transform completely into a pig, but keep her human mind.'
Once again, her clothes instantly disappeared, though this time she didn't seem to notice. You watched as she made her rapid transformation. Her hair receded, becoming white in color. As it receded, more white hair spread down her face and her body. Her brow shortened, cheeks and neck puffed up a little, and her snout grew and pushed her eyes apart, leaving her with a pig's head. Elizabeth blinked a bit to regain her focus. Her neck lengthened a bit, and her head realigned, attaching to her neck from the back of her head rather than its base. Elizabeth craned her neck forward to continue watching the TV.
As the changes spread down, her shoulders narrowed, with her body barrelling out. Elizabeth stretched her arms out, as her shoulder joints realigned to keep her changing arms beneath her body. As the white hair travelled down her arms, her arms shortened. The hair reached her hands, causing drastic changes here -- her thumbs shrunk away, her two middle fingers on each hand merged together into large cloven hooves, and her two outer fingers pulled behind each hoof into a pair of smaller toes.
Turning your attention to her chest, you noticed that not only had her breasts shrunk away, but now she had many pairs of nipples going down her front. The human curve of her spine disappeared, robbing her of her upright posture, and she started hunching forward. Her hips lost their womanly shape, as her body finished aquiring its new sausage shape. Elizabeth shifted in her seat, placing her newly-formed front hooves down to hold herself up. The joints in her hips realigned, forcing her rear legs out in the same direction as her reformed forelegs. As her legs shortened and restructured for an unguligrade stance, her feet lengthened, rounding out to match the shape of her legs, and her toes underwent a similar transformation as her fingers.
And just like that, the transformation had finished. Where once was a human woman was now a normal-looking pig. A farm animal, sitting on the couch like an animal would. It started looking around, as though looking for something. You quickly turned your attention back to the TV, so it wouldn't catch you looking. And then, it spoke. "It's so weird. I just can't help but feel that something is off." She no longer sounded like herself, instead sounding exactly as you'd expect a pig to sound were it able to talk. A little difficult to understand, but you got the jist of it.
"Well, your clothes did randomly disappear." You immediately regretted what you said, worried that you might've drawn attention to the fact that she was now naked again, save for her hairy body.
But she didn't seem to make the connection. "I know! And I can't get that off my mind, it's freaky! How did my clothes disappear like that?"
You shrugged. "I dunno, maybe they were poorly made and disintegrated."
"I wouldn't believe it if it didn't actually happen. I'm still a little spooked by it. I'm glad you're here, just in case something else happens."
You smirked at that. "Well, maybe the best thing to do is try to keep your mind off what happened."
"I'm trying, that's what the TV is for. But it's not working. Something about today just feels weird."
So she seems to be a little aware that something has changed, at least on a subconcious level. She just can't quite place her finger on it... or hoof, as the case may be. You wondered how much of a load your perception wish could handle. If you pointed out she was a pig, would she suddenly freak out? Or would she think you were crazy, or trying to insult her? Either possiblity was something you wanted to avoid, so you decided to try a more subtle tactic, one that at least wouldn't leave her angry at you. "Okay, so let me help distract you. Do you like pigs?"
