Sami taps her chin, and then says "I would love to go out and play with this, but not until we get a better feel for it....like what it feels like for me to be transformed, especially into objects, and maybe animals. I wanna know so I won't freak out....so let's try some things" and she walks over, swaying her hips seductively "Whaddya say, you want a little pussy?" batting her eyes and making a claw gesture at you. You run a hand along her side, and get the hint, tapping the app and her form seems to nearly melt in front of you, dropping to all fours as she shrinks and turns into a cat, who promptly runs her feline body along your legs, and you bend down to scratch behind her ears and she purrs in delight. You sit on the sofa and she leaps up, and then behind you, perching on the backrest above your head, playfully batting at your hair. You laugh and try to grab her, but she slips away, far too lithe and nimble in this form. She jumps onto the chair opposite you, and you turn her back to her naked self, her form glowing and growing.
"Holy crap, I was a cat, like all the way a cat, could even feel like feline instincts, that was amazing!" you smile "Just getting started babe" and you hit the app again, and she once again melts, shrinks, and reforms, this time as a snake, and you go over and pick her up, as she wraps your arm, giving it a nice muscular squeeze as she coils around it. She uses her forked tongue to taste you as she moves slowly along your arm to your shoulder. Tapping the app once more, the snake shrinks and reforms into a tarantula, and she climbs down your chest, able to scale your body easily in this form. You scoop her gently onto the table next to you, and then turn her into a potted plant, quite incapable of any movement, but very pretty nonetheless. Checking the app parameters, you smile as you change her back to human, but at only one inch tall, on the table next to you. She reforms and then blinks, looking down at her tiny naked self, and then up at her towering boyfriend next to her "Ok, this is fun, though gotta say I am more scared like this than I was as a spider even though about same height, wow." You lean over near her, and chuckle, your tiny naked girlfriend.
"Ok, so any thoughts on any of those forms babe?" She paces and then looks up "Of the animal, the cat was the best, but oddly, it felt really relaxing and pretty to be a plant...like I was so chill. I also think my time perception as a plant was altered, because it felt like only a split second, but betting it was longer than that." You nod, it was a good five minutes, so maybe different forms do mess with your perceptions" and you make a note in a journal "Ok, so...any other living forms you want to try at this moment?" Sami sighs "No, I mean a fish would be cool, but we don't have a tank to put me in, so we can't test that...but how about we switch over to inanimate objects now?" You blink and smile "If you're sure, any thoughts about where you want to start with that, maybe easy like a statue of yourself?" Sami cocks her head to the side "Not bad, but how about a mannequin instead?" You use the app connected to a browser to image search "Do you want a face or not?" Sami giggles "Such an odd question, let's go nope, no face" and you find a chrome mannequin with a totally smoothed head, and you first enlarge Sami back to human size, then immediately hit the app.
It's stunning to watch your girlfriend stop moving, lose all her identifying features, have her body smooth over, joints form, and simply stand there, fully turned into a mannequin. Getting up, you move and pose her a bit, then grab her shoulder, twisting and removing her arm, marveling at how easy that was, how she's just a real, fully functional mannequin. You put her arm back on and then consider what to do next, but briefly turn her human. Sami is naked and then blinks:
