She turns herself into a superheroine

Miranda looks to her left.

You look in that direction to see what's caught her attention, but that's where your desk is. It's so piled up with stuff that she could be looking at anything.

The small girl puts down the mirror and goes to your desk. She picks up a comic book and holds it up for you to see. "Is this what you like?"

The superheroine on the cover is exaggerated in every way. Huge breasts, muscular, and tall, she's the total package of powerful and sexy wrapped in a tiny costume that shows off everything she's got. You smile shyly, not sure if saying 'yes' would get you in more trouble or less.

Miranda opens the comic book and lazily leafs through it. When she gets to the end she throws it on the bed next to the mirror and stares at it. Several seconds go by without her giving any hint of what she's thinking.

Suddenly, a puff of smokes bursts in the room, covering Miranda. When it clears, she's completely different. She's at least 6'2", not counting the heels on her boots. Her shoulders are just a bit wider, which goes with her newly muscular figure. She's not a body builder, but she is imposing. Her breasts are big again, not quite as big as before but still huge, even on her new, larger frame. Her skin is perfect and her raven hair flows around her, blown by an unknown wind that doesn't effect anything else in the room.

Anything else except her cape. The dark black fabric billows behind her. The rest of her costume is also black satin, what there is of it. Besides the black thigh-high boots and the black gloves, she's only wearing a black corset that pushes up her impressive breasts.

"Wow, you look incredible, Miranda."

"Don't call me Miranda," she says, still with a slightly pissed off tone. "When I'm dressed like this, I'm Mega-Woman!" She floats off the ground and flies up to where you're stuck against the wall. "If you want to live some crazy fantasy, fine. We'll do this one. I just need to figure out what role you play in it."
