Spock's heartbeat sounded like a waltz.
Jim pressed his right ear more closely to Spock's right side, listening intently to the three-beat pulse of his friend's heart. (Six chambers, Jim thought absently.)
"Close call today," Jim slipped between pulse beats.
Jim wondered if Spock was holding back some comment about stating the obvious, but his reply came in a gentle baritone. "Indeed."
Jim was floating, grounded by the sound of Spock's heart and the feel of Spock's chest rising and falling beneath Jim's right hand.
After a few minutes, Spock pressed his palm to Jim's back, right over Jim's heart.
Jim smiled at their closed frame.
Gradually, he felt Spock's heartbeat speed up and realized the Vulcan had synchronized his own pulse to Jim's.
"You think we could dance a tango vals to this?" Jim mused.
Spock's chest rose, fell, rose… "If you refer to an Argentine tango of one, two, three, or no steps performed to any three beats of waltz music…"
Fell, rose…
"…then I believe so…"
Fell, rose…
"However, I would prefer to stay in our current positions."
Jim grinned. He brought his left hand to Spock's right hip.
One-two-three
One, two

Jim felt their heartbeats quicken together.
"Me, too."
A/N: I've always loved that Spock's heart is in his side, and I've wondered how his heartbeat might sound. Written for a friend of mine who is a cardiophile. Reviews are author food! :)
