The arse planet The magical size bracelet chapter 15 by SatireMarker

You looked around as you removed your hand from the bracelet, but it was pitch dark everywhere. The smell was bizarre and the heat intense, but you noticed you were...lying down on something now. On a solid surface.

You were not pinned against his underwear as you had wanted. You weren't pinned against anything. You were simply lying down on solid ground. You got to your feet and looked around but it was still unknowably dark. You were terrified. Maybe you'd done something really, really bad with the bracelet and you'd teleported to another planet or something. God knows this thing could do virtually everything else, so why not? You looked at the bracelet which emitted a faint glow and checked the display. It was then that you saw your size...

You were... 0.000001 of an inch tall. To you, Tread Rosenthal's left arse cheek was now the size of planet Earth. You gasped, shocked that you'd managed to enter the information in so badly. But you guessed you had done it without really looking. Still, this was a severe miscalculation.

The implications of your size boggled your mind. Now you realised why you were standing...to you, the ridiculously huge backside had gravity equal to that of Earth. You were standing on it, sideways. You realised that at your height almost every protein, cell, anything would be bigger than you...every pore in Tread's skin a gaping chasm for you to fall into. It was mind-boggling, amazing. Part of you wanted to explore it, but part of you was too freaked out to continue. You liked the idea of being so tiny you could literally live on this fantastic ass - what better place to live, really? - but it was no longer an ass to you. It was a celestial body.

You could turn the torch on and see what the landscape looked like, or you could grow up just a little bit.
