The tease of his nipple followed by the firm tug of hair causes Finnick to moan deeply into John's mouth, a sound that comes from far in the back of his throat. The sensation on his scalp is amazing, and the dominant movement to open Finnick's body and mouth up more to him... It flicks some sort of switch, a switch that melts the rational part of his brain into goo and makes him incredibly pliable in his partner's hands.

"Fuck..." he exhales the curse against John's lips. His cock is now aching for more, so he starts to work on the buttons of his pants to free it. He then goes for John's buttons as well, so they can at least rub against each other with less layers between.
