Sometimes Jim's really annoyed at himself for being...himself. Like right now, when he enjoys this sight objectively but still can't fall into it the way he should. He surveys her from under half-lowered eyelids, pushing her harder, loving how hot and wet she is and anticipating the moment of release.

Her throat's open for for the taking though, so he leans in and licks a stripe up it anyway, letting salt explode on his tongue before biting down, leaving another mark where it'll be difficult to hide.
