Tell her all about your powers

"It's not just getting hard," you tell her. The risk of sharing your secret is a huge turn on. "I can make anything happen."

"Anything?" Sarah raises an eyebrow is disbelief.

"I'll prove it." With a wish the two of you appear on a beach on a deserted island in the pacific. Sarah is dressed in a yellow bikini.

"Fuck!" she yells. "You really can do anything! Oh, wow! How can you do all this?"

"I don't know. I just... well... I woke up this morning and I could."

"Can you even change people?"

You nod. Does she suspect the changes you've made to her?

Sarah looks over the beach thoughtfully. Then she looks down at her own body. "Give me a figure as good as Madison's."

"What?" You look over her wonderfully curvy body. "But you look awesome already!"

Sarah pulls you to your feet. She kisses you roughly, pressing herself against you. Then she nibbles on your ear and huskily says, "Don't make me get rough, young man."

Drool slips out the edge of your mouth. "Yes ma'am."

You make the wish. Her body changes, pushing against yours in different ways. You pull back and see that Sarah is taller and thinner, plus more tone. However, her large chest is now even larger, with perfectly shaped breasts that beg for release from her straining yellow bikini top.

Sarah examines herself again. "Ooo, nice. I always wanted G-cups. Let's test them out."

The brown haired girl pulls off her bikini top, freeing her terrific breasts. She pulls you into them, rubbing them all over your face. Your cock gets hard again as your realize that you shouldn't have doubted her about this wish.

"This is awesome," says Sarah. "I know exactly what I want next."
