Navi could feel her pulse thudding in her ears, her neck. She was surprised it wasn't audible to him as well, and she sighed contentedly. He even smelled good, which should have been impossible. He should have smelled like sweat and exertion - which he did - but it was good. It made her feel at ease.
"Good. I - I'm glad." She felt honored to be someone special for him, and she was glad that she could do that for him. She wanted to for as long as he'd let her, and she let one of her hands stroke the hair on the back of his neck. It was soft, softer than she'd thought it would be, and that made her smile.
When she felt his teeth on her neck, she moaned faintly. She'd never done that before - she'd never had any cause to, until just then - and she felt her eyes close. "They're good surprises," she murmured. When he leaned back and looked into her eyes, she smiled back at him. She didn't want to move, but she wondered if they were about to get caught by anyone. She kissed him again, gently, then mimicked his gesture. She kissed his neck faintly, barely pressing her lips to it. She didn't want to use teeth - she wasn't experienced enough, and she didn't want to hurt him, but she did let her tongue touch his skin, tasting him. She made a happy noise in the back of her throat before sitting back up.
