The subtle reaction was more than Jim could ask for, and his lips curled into a crooked smirk, with just a hint of teeth to it. He canted his head and nibbled lightly along Bones's jaw, briefly brushing his lips down his neck. It was enough to make him want to flip them around on the bed and just go down on the doctor, and it took some amount of effort to stop himself from giving into that urge.

He unwound one arm from around Bones's neck instead, reaching for Bones's own hand and guiding it farther down, shivering slightly as he felt fingers brush across his stomach. He let go once he reached the navel, just a hint away from his groin, figuring that should be more than enough of a hint.

If not, then the way Jim's own hand moved to curl lightly around Bones's cock should more than do the trick.
