The tightened grip has him making another soft noise against Levi's neck, and though he was originally planning to move downward to explore his chest, the sensitive spot invites him to linger there and see what else he can coax out of Levi.

The stronger yank makes him gasp audibly, then melt completely into Levi as their lips meet again. Holy fuck. He moans into his mouth with feeling. Finnick is quickly becoming intoxicated by lust, and the tension that had been building in him before things had begun to escalate just makes this all the more intense. His tongue mingles with Levi's, tasting him, and his hips begin to grind his erection into the shorter man's thigh. His real hand scratches lightly down the center of his back, then puts hands on his waist to pull him in further. As their bodies fully press together, he feels the indication of Levi's arousal, which feels like a small accomplishment. The pressure between them now should provide Levi a little stimulation, without Finnick just up and grabbing his dick, in case Levi isn't ready for that yet.
