Johanna hates herself (or him) for it a little, but her body jumps with every nip, riding that edge of pain and pleasure. She hasn't relaxed even a little bit, too keyed up because of their proximity. It doesn't make it any less intense though - probably adds to it, if she's in an honest mood (she's never in an honest mood).

Finnick looks up at her like that, and even before he says no there's a wave of heat washing through her at the way he looks at her. A sound of frustration breaks past her lips, and she pulls her hand from between them to smack him in the shoulder. "Don't be an asshole!"
