Did...did Spock really just do what he thought he did? Since when did Vulcans...purr?

"Uh...Spock?" Jim cursed his life to hell when Spock cuddled up to him and made that noise again. Purred again. It was so hard to focus when Spock was like this. He was so lovable, so open and trusting.

Even being bond mates, Jim didn't get enough affection from his more than stoic bond mate. Not enough to be completely satisfied with their relationship. He wasn't Vulcan, and he wasn't about to gain their discipline. He wanted more, and goddamnit, he was going to get it.

"Babe, wake up. Hey, Spock." Nobody would have ever pinned Spock as a heavy sleeper. He didn't believe Uhura when she mentioned it. Alas, she hit the nail on the head. When Spock wanted to sleep, nothing could stop him from it.

"Jim..." He also wouldn't have guessed Spock talked in his sleep. He guessed it was the human side showing itself.

It was also incredibly endearing, some of the things Spock mumbled in his dream state. Jim would have recorded it earlier, to keep it for later...enjoyment, if he wasn't so sure Spock would not appreciate it.

"...Jim?" He blinked at the sight of his lover's worried expression he loved to see. The light caress on his cheek made him realize he was lost in thought again. Spock was awake now, so he had no time to waste. He wanted answers.

"Spock, babe. Do...you purr when you're happy or comfortable?" He couldn't resist the laugh that rose from his chest at the extremely uncomfortable look on his lover's face.

Spock sputtered and turned away in record time. Jim finally managed to stop laughing, but still wanted his answer, that Spock was clearly avoiding. He didn't see why it had to be such an uncomfortable subject for the Vulcan.

He thought about asking Uhura about it, but that would make him too jealous. So that wasn't an option. He couldn't kill his own Lieutenant.

"Jim, could we go to sleep? I am exhausted, Ashayam." Yeah, he wasn't getting an answer tonight. Oh well. It's not as if Spock would stop purring, seeing as it wasn't by choice he made the sound that was haunting his perverted mind.

He was right. Five minutes later, they were cuddling together and Spock was fast asleep. Just to make sure, Jim hit Spock's ultimate sweet spot. His most sensitive button for both arousal and relaxation, depending on how Jim did it.

So he took Spock's ear between his lips and hummed softly. He let his teeth graze, and his tongue drag.

Spock jerked and purred, loud and clear. It was a beautiful melody to Jim's ears, so he applied more pressure, and brought a hand to fondle Spock's growing erection through thin fabric.

He was rewarded with Spock's eyes snapping open, and a loud groan passing through his lips.

"J-Jim!" And fucking hell did he love it when Spock moaned his name in that shaking, desperate tone.

He licked the inside shell of Spock's ear, and at the same time increased the pressure between the Vulcan's legs. The silent scream of ecstasy was written on Spock's face, and Jim had never wished for a camera more than at that moment.

When Spock's orgasm-induced high was in full effect, Jim snuck a peck on the lips and curled into his lover's side.

The purr rumbling in Spock's chest had never made Jim happier.
