Jim hummed into the kiss before he pulled back slightly, a half smile on his lips, "I'm pretty s-sure there's something I was gonna do," he muttered and then with those words, he slipped off of the doctor's lap onto the floor between his knees and then he was leaning forward, his mouth brushing against the waistband of Bones' pants and then in an almost practiced motion, his lips and tongue deftly undid the button. He took the zipper between his teeth and pulled it down, his eyes on Bones'.
Bones was a little dizzy and a little light-headed, and so he raised his eyebrows when Jim spoke, unable to find his words. He gave a soft huff that (he would deny) sounded a little like a whine. He bit down on his bottom lip hard enough to make it bleed, watching Jim's expert skill and meeting his gaze. "Christ you're talented," He said, his accent broad and his voice low, as he ran a hand through Jim's hair.
