Chapter Text
The night prior to their arrival on Starbase 69, Leonard McCoy couldn't be more ecstatic. They were scheduled to arrive during a weeklong medical and science symposium. Doctors and researchers from all around the Federation were gathering to share and discuss their latest breakthrough research. It had been a long time since Leonard attended a medical conference, and Starfleet had granted them permission to stay for the entire duration. It was one of the largest conferences in the Federation. He used to dream of attending such events when he was younger.
"You have that look again," Jim’s voice traveled through their quarters. Leonard looked up from his PADD. He had a piece of chocolate with wasabi bean cookie topped with bacon and goat cheese in his mouth.
Leonard pulled the half eaten cookie from his mouth and held it between his fingers. "What you talkin’ about?"
"You look like an awestruck teenage girl going googly eyes for some hot movie star."
Leonard raised an eyebrow. "Have you been hanging out with the new ensigns or something?"
"No," Jim stated as if he was deeply offended.
Leonard was treated to a particularly delightful view as Jim dropped the towel from around his hip. He slid into bed next to Leonard. Jim took the cookie from his hand.
"You..." Leonard started.
He stopped when Jim bit into the cookie. He laughed when Jim made a pained face.
"What the hell are you eating?" Jim gasped out, his bright blue eyes looked watery.
"It's..." Leonard started.
"Wait!” Jim held up his hand. “Scratch that. I don't want to know."
Leonard laughed. The night before he had been eating watermelon soaked in Tabasco and strawberry syrup which seemed to have highly offended Jim.
Leonard took the cookie back. "Blame your kid." Leonard said offhandedly. Much to his annoyance, the baby kicked indignantly against his belly button.
Jim laughed out. "Right."
He pressed a kiss onto Leonard's belly. "Papa is just using you as an excuse to eat strange things, huh sweetie. Daddy knows." The baby kicked and performed a particularly spectacular somersault much to Jim's delight.
"Traitor," Leonard muttered.
"One point for Jim and zero for Bones," Jim cooed. He reached for a PADD and aimed it at Bones' swollen belly. "Come on sweetie. Do it again for Daddy," he cooed.
Leonard rolled his eyes and went back to his PADD. Of course he wasn't going to admit to occasionally... only occasionally looking up to watch Jim being adorable. The baby kicked and turned excitedly to Jim’s encouragement. He rolled his eyes when Jim set a piece of cookie against his belly. Jim let out a boyish cheer when the baby's kick caused it to go airborne.
"We have the universe's most awesome baby," Jim beamed. He covered his abdomen in kisses. Leonard's heart swelled from watching Jim. He had never imagined Jim to adjust to fatherhood so well. Jim gave his belly one final loving crease before nuzzling against Leonard's side.
He looked at his PADD before sighing. "You and Spock, I'm not sure which one of you two is more excited," Jim muttered.
"I take offense at being compared to that hobgoblin."
Jim laughed. He tapped his screen. "Any room for any downtime?"
"Downtime?"
"Uh huh," Jim nodded sagely, a sly smile formed on his lips. He rolled his fingers over Leonard's dark brown nipples. They hardened instantly to Jim’s touch. Jim smiled as he increased his rubbing. Leonard felt himself get wet. Jim smiled. He rubbed the back of his foot against Leonard's inner thigh.
"I'll have to see," Leonard managed to sputter out. He would call it a success that his voice didn't crack. He moaned when Jim kissed him. Blindly Leonard set his PADD down on the nightstand. Jim pulled him around. Due to much practice, he easily maneuvered his legs to straddle Jim’s broad chest. With a fluidity they had just recently developed, Jim's cock slipped easily inside of his almost leaking hole.
"God Bones, you're so wet." Jim muttered. His blue eyes dilating wide open.
"Who's fault is that."
He moaned as Jim rolled his hips in response. Jim’s cock hit a particularly sensitive spot causing Leonard’s back to arch backwards. Jim grinned as he rolled his hips again. He set his hands against Leonard’s thighs to prevent him from toppling backwards.
Leonard saw stars as Jim arched forward. "Come for me," Jim muttered, his voice going raspier.
"Jim," Leonard moaned. He rolled his hips with Jim, clamping down with his muscles.
"Fuck, Bones," Jim gasped out. "So tight.” His blue eyes diluted further. Jim managed to thrust forward one more time. The force took them both over edge. Jim's seed coated the inside of Leonard' already wet hole.
Satiated and completely debauched, Leonard wrapped himself against Jim. They fell asleep to the deep lull of the Enterprise as it sailed towards the starbase.
