Jim pressed in closer and slotted their mouths together the moment Bones parted his lips, tongue swiping past them and brushing against his own tongue. He let out a hum at both that sensation and the feeling of those fingers sifting through his hair, spreading a warm, soft shiver all across his body.

He shifted slightly on Bones's lap, but not too much or too suggestively. One hand moved up to brush through short dark strands, pads of his fingers dragging along the doctor's scalp, while his other hand curled into a fist into Bones's shirt. Jim had no intention of pushing for more just yet, but this was pretty nice. Just kissing and holding each other close.

Not something Jim was all that inclined to doing with anyone before. There was always a purpose or ultimate goal when he'd kissed someone in the past, but with Bones, the kissing was its own reward.
