Hearing that sigh and feeling Levi's muscles shake beneath his hands makes Finnick rock hard, the reward chemicals pinging through his brain. Seeing, hearing, and feeling the proof of Levi's pleasure is pleasurable in and of itself, especially since the man is normally so reserved and his expression so flat. He makes note of those reactions, and immediately acts on one of those notes, going back to the spot that made Levi shudder and sucking on it a little harder, worrying skin ever so gently between his teeth.

He presses fingers into muscle a bit deeper, and one hand slides down to Levi's ass again and gropes it gently. As their bodies come together, Finnick feels pressure against his cock and fingers tugging on his hair, and he moans softly against Levi's wet skin, open-mouthed. Levi will soon find that Finnick is quite vocal about his own enjoyment, which is partially a learned response from years of being sexualized, and partially just... How he likes to be.

"You can pull," he utters quietly near Levi's ear, referring to his hair. Finnick's scalp is very sensitive, and he loves any kind of touch there.
