That was a fun little surprise. She'd been fighting for centuries, sure with some vampiric, supernatural power behind her but this was far from her first fight even if she'd never sparred with anyone who had anything like Jacob's skills. She probably had forgotten more than he would ever learn, and he enjoyed seeing hints of her prowess.
He didn't fight her when he found himself on his back, grinning up at her, "I hope so." As pleased as he was, it didn't mean he was just going to lie there and take it. His hands free from supporting himself found their way to her thighs and slowly up to her hips. He was clearly just enjoying touching her, not yet setting up his break. "I can't say I'm not delighted to be here."
Flat on his back was bad. He had no leverage in that position and even though she weighed so little she had the advantage keeling him pinned with just her body weight. She'd left his hands free though and that was a mistake on her part. He could distract her with them and work on his leverage. Normally he would have gone for the shoulder right away but instead he let one hand move to and squeeze as much of her butt as he could reach. During the squeeze he did two things surprisingly quickly. The first was getting an arm up, grabbing her opposite shoulder as the arm pressed across her collarbones. The second was rolling his hips from side to side, freeing him just enough for him to find leverage and turn them over again to pin her against the floor. This time he kept his body pressed too close to hers, his lips barely an inch from hers, holding her down with the one arm and getting one of his thighs between her legs so she couldn't wrap around him again. "Maybe I don't believe in playing fair."
