Right Now!

You've never had a superpower before. In fact, as you think back, you are pretty sure that superpowers aren't a thing. They're made up, stuff for comic books, stuff for fiction, stuff for kids.

Only now, staring down at your dainty feet inside your younger sister's socks, you seem to have gained a superpower.

Your mind is running a sprint. How had that creature done this? Was it magic? Is magic real? What should I do with it?!

That last one, though, is a silly question. You know exactly what to do with it.

It is late in the evening. Your mother is watching a show on television. Hannah, your older sister, is in her room working playing a video game. Your younger sister, Shae, is out dancing with her friends. She had graduated from high school in June, and had spend most of the summer this way, enjoying her freedom as an adult, partying, being irresponsible. You don't blame her. In your first post-high-school summer you had gone on a tear, so much so that you hardly remember it. Maybe it was a right of passage, maybe it was the nature of growing up, but whatever it was, it meant that Shae isn't home.

Shae's room is next to yours, so it is a simple matter of sneaking in without being caught. You don't need to be a master burglar to achieve your goal, but still you are filled with anxiety as you sneak out of your room. What if you are caught? What would you say?

I'm just collecting her laundry...

or maybe

I thought I heard something...

or even

I'm stealing her clothes so that I can get freaky...

That last one makes you grin, taking the edge off of your fear. Soon enough you are safely in your sister's room and sliding open a drawer. You luck out. Inside is a collection of sleepwear. You push aside two pairs of flannel pajamas and a long t-shirt, only to find what you want. Holding the soft pink babydoll up in front of you, your grin intensifies. You've never really thought of wearing a woman's clothes before, but something inside of you, something strong, something hot, is driving you to try it.

Back in your room, you shout to your mother that you'll be heading to sleep, just to ensure that you won't be disturbed. It only takes a minute after you lock your door to get undressed, but getting dressed, while you have much less to don, takes you longer. You feel the soft silky material of the babydoll, first with your hands, then you rub your face in it, then you softly rub your now erect penis. The cups for the breasts are large, bigger than you thought your sister's breasts to be, although you don't really look to assess. They are are embellished with lacework and topped with small black bows on the straps.

Lifting the babydoll over your head, you slowly slide it down, enjoying the smooth feel of the material over every part of you. Once it as settled, you don't have a time to wonder what would happen. Taking only a moment, your torso from the neck down to your thighs, completely transforms into your copy sister's body. Your legs, above your dainty feet, are your normal, hairy feet, and your arms are still your own, but your ass, your breasts, your stomach, your vagina...

That's all you care about, really, and so, settling down on your inflatable mattress, you let your left hand slide down to your vagina to show it exactly how much you care.
