You flip the switch back, and look for something to swap with. You notice a big statue - probably about twice your size - standing in a corner. Before even deciding what to do, you just pressed the button. You suddenly fall on your chest, which was surprisingly painless. As you struggle to get up, you notice the statue now has a flat chest made of flesh. You look into your shirt and see the same texture of the statue connected to your flesh. The breasts were resized to fit your body, but they were still pretty heavy. You swapped back as soon as your back started to hurt.
You then wanted to experiment with the statue a bit, and flipped the switch. You saw a girl waiting near the statue. You pressed the button and swapped her ass - including asshole - with the statue. The girl looked much more stiff, indicating she couldn't move her hips anymore. The ass was bare om the statue, and you could clearly make out the asshole inside. You decided to let them be, because the girl looked pretty normal.
You then see a boy walking around, and decided to swap his head with the statue. You saw the boy fall down limb and the statue didn't move either. The boy looked like he was just standing there being bored. You felt bad for him and swapped him back... With a twist. You swapped his face back, but left the statue's head on his body. He stood back up and continued on his way.
You then flipped the switch again as you wanted to do one last experiment. You pressed the button as your rock hard dick appeared on the statue's crotch, as your crotch now contained nothing but stone. You walked towards the toilet, and tried to pee. To your surprise, pee actually came out of the stone, through a non-existing hole. You wiped the stone off and shuddered at the sudden wave of pleasure that it sent into your body. Feeling excited, you started rubbing it until you climaxed.
