"Fly"

The boy looked down at his brown-haired companion, and he could see the silvery star tattoo on her cheek glitter in the moonlight. He felt a surge of affection for his good friend in front of him, and he suddenly wanted to give her anything she asked for.
"If you could have any power you wanted, no strings attached, what would you choose?"
She thought for a second before a smile lit up her features. She spread her arms out and said, "Fly."
Of course, this amazing girl would have to choose the most difficult to teach. He was determined though, and soon thought of a way around the obstacles.
"Close your eyes," he commanded gently. She obeyed after giving him a questioning glance.
"Don't open them until I tell you."
He touched her star tattoo with one hand and held her hand with the other. He felt the weightlessness wash through him and into her. The girl's mouth widened in surprise, and she started to move her hand away. But the tall blond boy had firmly entwined his fingers with hers. After a moment, he removed his hands.
"Open your eyes."
The girl looked into the lake beside her and gasped at the sight. Two transparent, shimmery blue wings shaped like a butterfly's appeared behind her bare white shoulders.
"Can I...?"
She couldn't bring herself to voice the hope.
"Try it. Just jump."
She kicked off the ground, then brace herself for the inevitable impact. It never came. She looked at the beach in surprise. She was floating about a foot above the ground. She started laughing. It was an exhilarated, tinkling sound that sent a thrill through the boy.
