"God, Jim!" McCoy gasped after being thoroughly kissed by one James Tiberius Kirk, "Are you trying to kill by limiting my supply of oxygen?"
Jim smirked. He knew that was Bones' way of giving a compliment.
"Wanna get revenge on me?"
Then McCoy growled, actually growled low in his throat like he was an animal about to pounce on his prey. Jim's eyes grew rounder and his pupils grew right before his eyes.
"Well, that wiped the smirk off the smug bastard's face," thought McCoy.
Suddenly he felt himself being pinned to one of his office's walls. He felt a knee nudge his legs apart and come up to his crotch. Bones grabbed Kirk by the shoulders to get a better angle for friction and began thrusting against his friend's leg.
"Jim, it's been too long. You have no idea how badly I want this," he said in a choked whisper.
Jim reached up a hand to pull his face close enough to his to kiss him. This time the kiss was slower, but had the same amount of feeling go into it. It felt so good to be this close to Bones.
Against his neck he felt McCoy breathing heavily as his pace quickened, and he gripped Jim tighter, like if he didn't hold on, Jim would disappear.
"Easy Bones, I'll take care of you."
"Yeah, kid," he panted, "I know you will."
