Hearing S/O's heartbeat with Black O.O
It took a lot to lure Black into resting with his skull against your chest. He'd been awake for far too long (again) and you had to use all your powers of persuasion to get him to even sit on the couch with you. After half an hour of coaxing, you finally got him where you wanted him. "Just close your eyes," you said, your hands already rubbing soft circles on his back.
"This is ridiculous," he muttered. "What is this going to do?"
"Do it for ten minutes and then I'll let you go wherever you want. Now close 'em!" You punctuated your words with a gentle tap on his spine.
"Fine." He huffed and closed his sockets. You focused on breathing slowly and rubbing circles on his back. At first, you felt him relaxing, just a little bit. Then he stiffened and tilted his skull to look up at you again.
"Oh! That's my heartbeat."
Black looked at you for another moment. "It just...makes that sound? All day?"
"Yup. Makes it all day. It's pretty soothing, huh? Sometimes parents give their babies toys that have a fake heartbeat in it, because the baby got used to hearing Mom's heartbeat in the womb, and it soothes them."
"Is that why you wanted me to rest just like this?" he asked, putting his head back against your chest. "So I could hear it? You thought it would soothe me?"
You blushed a little bit. "Good job, detective. You figured out my scheme."
"Well," he said, his usual smugness returning, "I am a very good detective." He laid his skull against your chest again. "I suppose I could rest here for a few minutes."
"You can rest here as long as you like," you told him, bending to kiss his skull. "I love you, Black."
"I love you too, dearest." He snuggled into your chest and you felt him relaxing against you until he finally drifted off to sleep, with the sound of your heartbeat echoing through his skull.
