Maybe he doesn't have to worry about being good enough, just good enough for her. That thought alone is enough to calm any anxieties he might be harboring about his lack of experience in the area. He almost can't put a description to what he experiences, resting a palm against her abdomen to feel her tense and shudder. It's a combination of being excited by her, very excited, and soothed by her very presence. Her words die in her throat and he murmurs her name, low and against her skin, before his fingers pick up the slack and he teases them into her, slow and rhythmic.
