Jenny was confused and terrified and aroused. The day had started out normally enough, although ditching school wasn't a part of her usual routine, it wasn't a particularly strange decision, nor was her choice to spend her free time shopping. B-but this?! That strange urge to climb onto this plinth and strike a pose? And what had happened afterwards, she had somehow transformed into exactly what she had been imitating, a mannequin! J-just another plastic dummy! And no one seemed to care, or even notice what was happening to her, what had happened to her! Everyone around her just continued to go about their day, blissfully unaware of her existence!
How could this have happened to her? Why her?! So many terrified thoughts rushed through Jenny's now hollow head, she almost didn't hear as someone began to speak behind her. Quietly eavesdropping as if she had a choice, Jen grew only more terrified, these people were treating her like she really was a mannequin! They were going to move her to another part of the store!
Jenny would have objected, loudly, if she still had the means to do so. But as a Mannequin all she could do was remain still as someone grabbed onto her, pulling her off the plinth and causing her to topple over haphazardly, only barely caught before slamming into the floor.
The feel of another person's hands on her, it was just too much! Her new body was already just so ridiculously sensitive, that it just sent her over the edge, but her shrieks of pleasure never left her lips.
She couldn't focus at all as she was being carried off, she didn't even know where she was being taken, but when she finally came back to herself, she was able to recognize a section of the store she normally didn't venture. If she still could have, she would have blushed. T-the Lingerie section!
“Alright, now to get you in some more fitting attire...” A cute girl said, a girl she recognized as being one of the employees of the store.
Jennifer whined as the girl began to awkwardly disrobe her stiff plastic body, the feel of her hands on her plastic skin, and the feel of her clothing scrapping across her body... But even past the arousal she still retained enough of a sense of self to feel embarrassed as she was rendered nude. Although her new form had no details to be embarrassed of, her crotch and breasts both as smooth as a doll's.
Humming gently, the girl held up a set of lingerie against Jenny's body, bringing an imaginary blush to her cheeks. After several choices were exhausted, the girl finally seemed to settle on a rather risque set in black lace. Still humming a simple tune, the girl began to dress Jenny in her new clothing, slowly and awkwardly sliding it onto her unmoving body, and sending waves of pleasure rippling through her. Finally, the girl finished dressing her, and picked her up by the legs, and set her upon another plinth before walking away.
Please let this be just some sort of horrible dream... Jenny begged, to no avail.
