"I wonder... Come closer, I want to try something, that might be... dangerous." And she didn't want to hurt him, she couldn't recall a time that she had ever. "It's new, but it... It's got to be more than decoration. But if it doesn't harm you." It had be be more than a show of her attraction to him.
And then it happened. She could feel it she took her hand away from him and began to wave both at her face, in attempt to stave off the sneeze. But when it didn't go, when she knew it was inevitable Shannon gave him a moments notice because she didn't know what was going to happen. "Duck!" Then her hands came together to cover her nose and her mouth. She held off a moment later. She hoped long enough that he could take cover. And the most comical high pitched sneeze was muffled in her hands.
And the end result was not one she could have predicted. As two white wings sprung from her shoulders. Too small to lift her, or to more than flap.
