"What are you doing Captain?" Spock asked in concern as he entered Jim's quarters.

"Not a good time Spock," the blonde stated before draining his glass.

"Are you drinking alcohol?"

Jim huffed. "You might want to leave before I upset your Vulcan s-sen-sensibilities," he remarked as he got to his feet.

"You are drunk," the Vulcan stated. Jim waved that away. "You are to be on shift in less than ten hours, you will not be in optimal-"

"I'll be fine-" he started, then tripped over his own feet. Spock caught him. "You don't want to do that," he stated.

"I do not want you to injure yourself in your inebriated state," he said firmly as he steered the blonde to his bed.

"You need to leave."

"Not until-"

"Now," he stated, blinking as his knees hit the bed. "You know, you're really attractive," he murmured.

"Thank you. I will not remind you of that in the morning."

"I've always thought you were pretty," he stated, gripping the Vulcan when he attempted to straighten. He leant forward, pressing his nose against the brunet's neck. "You smell good too."

"Cap-" he cut off as Jim placed a kiss against his skin. "Jim, you are drunk-"

"You can feel how much I need," he remarked, "can't you?" The Vulcan nodded. "You're not going to leave me in this state, are you?"

"You favour-"

"I sleep with men too Spock," he stated, tracing eager fingers down the brunet's torso through his top. "And before you ask, never Bones." He tugged the brunet's top free of his waistband, venturing eager fingers over skin, but went no further than the Vulcan's waist. "Please," he breathed.

"Enough to sate you, no farther," he stated.

Jim grinned wickedly. "I hope you don't need much sleep."

Jim woke with a pleased hum; he hadn't felt this good since last shore leave. "Shit. Uhura," he cursed.

"Do you regret that she was not here last night instead?"

Jim blinked at the Vulcan. "You stayed?"

"I could not in good conscience leave, not when any number of afflictions could befall you in your drunken state. Please answer the question."

"Huh? Oh. No, I was happy with the company, it's just that I know she'll be pissed at me."

"Why will she be upset with you?"

"Because you're dating," he replied slowly.

"Lieutenant Uhura and I do not have a relationship," he stated.

"Does she know that?" The Vulcan nodded. "Bet that was a fun conversation," he muttered. He glanced down. "Sorry I came onto you so strong, Spock. I get especially horny when I drink, sorry again."

Spock tipped the blonde's chin up with gentle fingers. "Do you regret it?"

"The only reason I regret my actions, is that I know you do not invite touch, and only reciprocated out of a sense of obligation."

"That was not why," the brunet stated. "And I do not find your touch displeasing."

"Really?" he asked with a warm smile.

Spock nodded. "I would be willing for a repeat."

Jim grinned. "Don't worry, next time I won't be drinking," he stated. "In fact, fancy another round?" he asked with a wicked grin.

"Already?"

He nodded and shifted until he straddled the brunet's hips. "You're hot, and naked. That's enough for me to be ready," he stated.

Spock gripped the cheeks of his ass and spread them. Jim shivered with a needy moan. "I take it you do not require preparation?"

Jim reached between them and gripped hold of the Vulcan's thick, double-headed cock and pressed the head against his still-stretched hole. "Now, please, now," he panted.

"As you wish, Captain," he replied, lips curving in a small smirk at the blonde's shiver. "Release me Jim," he ordered. He did so and was rewarded with a hard thrust from the Vulcan, sheathing himself in a single stroke. Jim let out a wrecked moan. "You make such pleasing noises," the brunet purred. "I wonder how many more I can wring from you in the time before our shift?"

Jim shivered. "God, what you do to me," he murmured, gripping the brunet's shoulders tight. "Take me Spock, make me yours," he purred, inches away from his mouth.

The Vulcan took his mouth in a heated, claiming kiss, before he set a hard, fast rhythm, sliding deep with every stroke. Jim moaned into their kiss, tightening his grip as he surrendered to the Vulcan.

Spock pulled back, a protesting noise falling from Jim's kiss-darkened lips. "Cum for me Jim," he ordered. His human complied with another pretty, enticing sound.

"You're still hard," he breathed, licking his lips.

"Have you not realised Vulcan stamina yet Jim?"

"Wasn't sure if last night was a fluke," he teased with a grin. "I just enjoyed the ride." He licked his lips. "Spock?"

"Yes Jim?"

"What do you want from this?" he asked, releasing his grip of the Vulcan's shoulders.

"Do you require touch from females?"

"Not as long as my needs are met," he answered honestly.

Spock cupped his human's cheek, causing him to shiver. "Then I wish to have a relationship with you," he stated.

"Good," he replied, leaning into the brunet's touch, "because you've ruined me for other men."

"Oh?" the Vulcan purred.

Jim shivered again at the heated look in the brunet's eyes. "Yes," he breathed, licking his lips. "No one else was ever able to keep up with me, let alone sate me," he stated without ego. "Though, you haven't seen me at my best yet," he added with a wicked grin.

"I look forward to it," the brunet replied, lips curved upward at the corners. "Continue."

Jim's expression turned wicked as he leant temptingly close to the brunet's mouth. "In case you haven't figured it out yet, Spock," he spoke, breath fanning the brunet's lips, "I'm a cock slut." It was the brunet's turn to shiver. Jim licked his lips. "And your cock is perfect." The Vulcan's eyebrows arched. "By far the most beautiful cock I've ever seen," he stated. "I'm a bit of a xenophile too," he added with a shrug.

Spock tugged the blonde forward into another heated kiss his human gladly submitted to. "Our time is limited," he stated as he pulled back. "But I look forward to claiming you so thoroughly you never forget you belong to me," he purred hotly.

Jim shuddered, already hard. "That go both ways?" he panted.

"Of course Jim."

"Then please," he whimpered. "I need you, for as long as we have."

"My pleasure, t'hy'la," he murmured, more than happy to see to the needs of his human, already planning how he could deliver on his promise after their shift.
