Bigger, then she finishes transforming herself

Miranda stands there, looking at her breasts in the mirror. They swell again, then some more. She pauses, then they grow significantly, up to the size of cantaloupes. She giggles and they shrink back a little bit. She's left with very large breasts, probably G-cups, but not out of proportion with her body.

She turns your way and catches you smiling, making her roll her eyes. "You're such a freak. I can't believe you made me drag those watermelons around. Isn't this better?"

You nod. They could always be bigger, but now is not the time to disagree with her. That time might never come again, now that she has the power. Besides, her boobs are pretty damn big!

There's another slight change, but at first it looks like it might just be a shifting of the light. It's hard to tell what's different, it's something that's all over but it's not her skin. Then you realize that her muscles are more tone now. It's subtle, so she didn't make herself into a she-hulk or anything. The extra definition looks great on her.

Miranda's hair shifts around, loosening her braids until it all falls free, flowing down her back like a glossy black waterfall. It's perfect, not too flashy a style, but very flattering to her delicate features.

Finally, clothes appear on her. She has on brand new, white tennis shoes that match her white pleated skirt. Her top is pink, sleeveless, and tight enough to show off her impressive chest.

"There," says the girl who is now probably the world's hottest Asian teen. "That's how you improve a girl's body. Hot, but not ridiculously proportioned."

"Un huh," you manage to mumble.

The mirror disappears and Miranda walks over to where you're pinned against the wall. Your rock hard cock twitches, pointing at her. She shakes her head at that. "Now I should figure out what I'm going to do about you."
