First you test by moving your arms.
You could move them. Good, you might be able to grab the remote. If this next test fails.
You try to move your solid white plastic fingers. They move also.
Perfect!
It doesn’t matter the mold lines you could make the body move how a human body did.
Maybe even better?
You try to test it by placing your white mannequin hand on your still human head and turn it 90 degrees. Then 180 degrees. Finally 360 degrees right back to the front of your body.
This was even better than you already planned.
You look down at your chest, if you had one complaint it was the size. They were somewhere between A and B cups.
Still though, they got the message across.
You open the front of the blue bikini top and find two smooth white mounds devoid of nipples. You test grabbing one and find it solid.
Another test you knock on your plastic stomach and find it hollow. You shiver at this and rap your arms around your shoulders.
You were just a human head controlling a mannequin. The mannequin was still just a mannequin it had not filled with muscles to let you control it.
For your last experiment you peal down the front of the blue flower bikini and rub your smooth white plastic crotch. You nearly cross your legs at the feeling. Shivering again. There was definitely something there, but it was numb and sealed by plastic. Also still hollow like the rest of your body below the neck were skin met plastic. But definitely more sensitive, and enjoyable than the rest of your new body. You reattach your blue bikini to the way you found it on this body.
You look down at your solid white plastic toes and wiggle them dispite them appearing to be solid white plastic. Time to get off this stand.
You try to step off the mannequin stand only to fall back into a rack of bikinis, not use to your new balance. You make a hollow noise as you land on your butt and knock into a bikini stand.
Bikinis fall ontop of you and you sigh, checking your new body for cracks. While you sat in a pile of knocked over bikinis.
You look at your feet and noticed the stand was still attached to your right foot.
You pull out the stand and find the metal long metal pole goes all the way to your knee in your right leg.
You rub the soul of your plastic right foot were the hole was and think you could store something in the hole.
Like the magic remote.
You grab the remote and slide it into your right foot hole. It fits inside you perfectly.
You look over the top of the rack and see the store owner still distracted with the mother and her daughter. This time showing them a mother and daughter mannequin set with matching swimsuits, a dark blue one piece for the daughter mannequin. And a dark blue bikini for the mom mannequin.
They didn’t notice you knocked over a rack of bikinis.
This gives you an idea.
