Then John is pulling his hair again, and teasing his neck, and he feels a big hand wrap gently around his cock, and Finnick cannot help the whimpering whine that escapes him. His submissive brain rears its head again, and for a moment he just melts into John, throwing an arm around his neck to hold himself up on weakening knees. He further makes a few humming whines of pleasure before reminding himself not to be a pillow princess, taking John's shaft in hand.

"It's good- it's really fucking good-" he murmurs breathlessly against John's lips. It's not like anything particularly mindblowing is happening, in the grand scheme of Finnick's sex life. It's hot and heavy, but nothing he hasn't done before. However, he's learned that having trust in a partner, feeling cared for as a person while in bed, trumps everything else. Feeling like someone values him for who he is and doesn't just want to use him is key to Finnick trusting them and having a good time. John is so sweet, so clearly caring, that it opens Finnick right up.

He feels as though he should check in too, though. He strokes John slowly as he asks:

"You okay? Slower, faster? Less, more?" It's important that John feels in control of the pace here, given his level of experience.
