Grow back to normal and have fun with your powers

You quickly grow back to your normal size, finding yourself standing again in your backyard.

Sophie: "That was cooky! Alright, testing the limits of my powers is great and all, but who knows what kind of weird shit I'll find if I go too deep down there. I just know that some jackass physicist is going to kidnap me and **** me to prove or disprove string theory if they found out about this."

Your neighbour Gerard, who has a degree in physics, walks by.

Gerard: "Damn straight I would!"

Sophie: "Yea, so none of that for me. I'm gonna do actual fun stuff."

First things first, you go to the store to buy a bag of candy, and then shrink yourself inside of it, so that you can have your own personal candyland. Your food intake apparently scales to your size - you get full from eating just a single chocolate raisin.

Next you shrink on your bed. Now you have a king-size bed. An emperor-size bed! A Goddess-size bed! As much bed as you can imagine! You could have a whole RPG adventure under the covers if you felt like it. The only problem with a bed this large is that at a certain point the fabric stops being soft, as it no longer deforms under your weight. Maybe you should invest in a fine silk cover? Nevermind, at those prices you might as well buy an actual king-sized bed.

But then it occurs to you that these powers could be abused for sexual gratification as well! There are sure to be countless partners who are willing to frick frack a superhuman of any kind, let alone such a desireable type as you.
