It shouldn't have surprised her that he deepened the kiss, but it did. It seemed bold of him, and if there was anything she knew of that Chase tended not to be, it was bold. He was gentle. Unassuming. So it meant something to her, that he was leaning in, kissing her back, making her shiver as his hand smoothed up her spine to cradle her long neck in the palm of it. Her eyes fell closed and she couldn't help but whimper in pleasure. His lips were full and soft and she moaned against them quietly as her hands came up. She laid them to his face, tracing her fingertips over his cheekbones as she returned the kiss.
It was slow at first - hesitant, testing the proverbial waters as her tongue pressed forward to brush against his own. It was slow and sweet, until it wasn't, the kiss becoming more and more passionate the longer it went on. Just the once, she told herself. Just once, just for a few minutes, and then she'd stop.
He was, perhaps unfortunately for her good intentions, far better a kisser than his self doubt with imply. Nessie was trembling and she coaxed his tongue between her lips, sucking and nibbling, wanting him to like it, too.
