"Oh, I'm just not a math person, David. I've accepted it." She tossed the towel and reached for her t-shirt.

"Buggar that!" he growled, pulling her to him. "You are absolutely brilliant!

You are the smartest, most amazing woman I've ever met, and I'm going to prove it to you!"

Her breath caught and she stared at him, bemused. "Catherine, you've heard me talk about the universe having like a geometric blueprint, a cycle that repeats over and over…" She nodded, but shrugged. He'd talked and talked about it, but she'd never really understood it.

"It's in everything-the shape of a sunflower, in crystals, in the center of the Milky Way, in our very cells and DNA-we all have this sacred geometrical pattern." He sat on the futon was opened flat from earlier, pulling her into his lap.

"And it all starts with a basic angle, one simple equation."

He flipped her into the futon and she squealed, laughing, as she sprawled out before him. His excitement was catching, and she was admittedly curious.

"You, my little duck, are a hands-on kinda girl, hm?" He smiled down at her, rubbing her ankles with his thumbs. She shrugged, still smiling a little dreamily up at him, her body tingling like it always did when was displayed like this for him.

He opened her legs, and said, "Don't move." She raised her eyebrows, but she didn't.

"Let's start at the beginning… first define an angle," he said. "Tell me."

"When two lines intersect in a point, called a vertex, the circular span between the lines is called an angle," she quoted. She could have probably quoted the whole text, and yet she didn't have any real comprehension of it. The minute the pencil went to the paper, she was lost.

"Yes, such a good girl," he murmured. She saw his gaze fixed between her thighs, his eyes growing darker. "When two lines," he repeated, his hand starting at her ankles and sliding up the impossibly long, smooth length of her legs.
