Author's Note: More thorough smut for you this time, enjoy!

Jim entered Spock's quarters at Academy and the half-Vulcan arched an eyebrow. "I would ask how you were able to enter, however, I believe I would not like the answer."

"You're probably right," he replied as he leant casually against the wall. "So?" The brunet blinked. "You wanted to see me about something right? Shoot."

"I find myself dwelling on a phrase Dr McCoy said to me," he stated.

"Oh God, what southern colloquialism has he come out with this time?"

"'If you're riding in the Kentucky Derby-'"

"'Don't leave your prize stallion in the stables'," Jim finished. "I'll take that as the compliment it was intended as. Don't worry that you offended him with your response, he's that terse with everyone," he assured.

"Do you know what my response was Jim?" The blonde shook his head. "'A curious metaphor, Doctor, as a stallion must first be broken'," he stated.

"Okay, you might have pissed him off with that. The need to 'break' a stallion is a misconception," he stated. "If you do that, the horse will never trust you again. It might take more time, but it's a better method to coax a horse into trusting you, and then train them."

"Even with that, the phrase is still applicable to you, Jim," Spock stated. Jim's eyebrows rose. "It is my opinion that you have the makings of a great Captain, you simply need to reign in your worst impulses," he stated.

"Volunteering to be my First Officer, Spock?" he asked with a grin.

"Yes," he stated. "However, I was intending on using a specific method with you," he continued.

"Oh?" Jim asked, smile still in place.

"Punishment and reward," he stated. "When the risk of your plan or action outweighs the benefit, such as your fight upon the bridge, I will dispense a punishment. However, when one of your more lateral ideas 'pays off' as you would put it, then I will provide you with a reward."

"You mean, like with Nero?"

"Exactly," he replied.

Jim's head tilted as he regarded the half-Vulcan. "And what nature would these rewards or punishments be?"

"Sexual," he stated. Jim startled. "Given what I know of your character and exploits, I came to the conclusion that that would make the most impression upon your future actions. Also, given that your sexual partners have been from many non-human Races, including one which is a hermaphrodite, I determined that you would not be opposed to having me as a sexual partner."

"I wouldn't," he replied automatically. "But," he continued, holding up a hand, "you're in a relationship, and I don't help people to cheat."

"You allude to the kiss you witnessed between myself and Lieutenant Uhura?" Jim nodded. "After the events on Vulcan, she gave me a comforting touch, and as I did not react negatively to it, she took that as a sign of greater intent on my part. After the events with Nero were resolved, I discussed the matter with her. She is aware that while I respect her and her abilities, I have no intention of a relationship with her."

Jim licked his lips and blew out a breath. "What sort of thing did you have in mind?"

Spock's lips curved in an almost-smirk. "Given that you were ejected from the Enterprise, it is my opinion that you were suitably punished for that incident on the bridge, and my reaction on the subsequent occasion was also suitable punishment. Therefore, you are due a reward for your plan, and ultimate success against Nero," he stated.

Jim grinned wickedly. "Which would be?" he asked cockily.

Spock used the tip of two fingers to tilt the blonde's chin upward, and took his mouth in a heated, claiming kiss Jim instantly responded to. He pulled back only after he had made the human moan. He met Jim's gaze solidly. "In these moments, you are not in control," he spoke firmly. "I am." The blonde shivered. "It is my decision what punishment or reward your actions deserve." Jim licked his lips. "Ask," he ordered.

"We will share touch outside of that, won't we?" he asked breathily.

Spock's lips curved upward, and he cupped Jim's cheek gently. "Of course," he assured. "Once I touch you, I will not want to limit future instances any more than our duties demand."

Jim leant into the touch. "It won't stop me from asking for what I want," he stated with a wicked grin, "but I can accede to your control." He licked his lips. "About that reward?"

Spock gripped hold of his waist, and tossed him onto the bed. His lips curved at Jim's shiver. "Do you enjoy that I am stronger than you Jim?" he asked as he stalked to the end of the bed.

"Yes," he spoke breathily.

"Noted. Your clothing is unnecessary," he stated. Jim's hands went to the bottom of his top. "Did I order you to do that?" Jim's hands stilled and he shook his head slowly. "Remove it," he ordered and Jim instantly complied. Spock's lips curved again as he removed Jim's boots. The blonde's eyes filled with need as he watched Spock's movements intently. "Lift your hips," he ordered. Jim complied and Spock's long, elegant fingers tugged off his regulation trousers. An eyebrow arched as he found only bare skin beneath.

Jim grinned wickedly. "Not like you could tell, right?"

"How many others know of your preference?"

"Do you really want me to answer that?"

"All of your past partners?" he guessed, arching his eyebrow once more.

"Not all, and some might have thought it was out of convenience, given the timing," he answered honestly. He scraped his teeth over his bottom lip. "Please touch me Spock," he breathed.

"Are you eager for my touch Jim?" he asked before stripping with economic movements. The blonde nodded rapidly, his eyes flicking over every bared inch of Spock's toned form. "Do you like what you see?"

"I want to touch you," he responded instantly. He grinned. "But I can wait until you've delivered your planned reward."

"Keeping you in line will be a fulltime occupation," Spock remarked as he crawled onto the bed, settling between Jim's parted legs.

"You volunteered," he spoke breathily.

"I wonder what it will take to render you speechless?" he mused.

"You'll have to find out," Jim retorted with a grin.

"Indeed I will," he murmured and trailed two fingers down Jim's torso. The blonde shivered. "You are truly enjoying this," he murmured. "Interesting," he mused, as his fingers came to rest on his naval, "that one so determined to become Captain, would enjoy having control taken away from him."

"Spock," he breathed with a hint of whine. "Please."

The half-Vulcan wrapped a hand around Jim's turgid shaft, and the blonde cried out. "It is good that I have heard of your stamina," he murmured as he began to stroke, expertly touching the blonde as he preferred.

"Why?" Jim gasped.

"Because it means I can be as thorough as I wish with your reward," he stated, lips curved into an almost-smirk. "And with your future punishments," he purred.

Jim shuddered and came. A trace of a blush coated his cheeks as he panted hard. "If it wasn't for your touch-telepathy-"

"You would feel embarrassed about how quickly you attained orgasm?" he finished. Jim nodded. "Given how quickly you recover, Jim, surely it does not matter?"

Jim licked his lips. "What else did you have in mind?"

"Do you require a moment to prepare for sex?"

A light blush coated Jim's cheeks. "Not necessary."

"Explain," Spock ordered.

Jim licked his lips. "I've always been attracted to you Spock – even when you were trying to get me kicked out of Academy – so, I uh, took the edge off before I came to see you," he admitted.

"I find I am disappointed that I was unable to watch," the brunet remarked conversationally. Jim shivered. "I do not object to you ensuring you are clean, however, you do not object to my viewing other preparations in the future?"

"Not-" he cut off and cleared his throat. "Not at all," he breathed.

Spock stroked a hand down Jim's thigh. "You find the thought as alluring as I do," he murmured. "It seems we are well matched Jim." His eyes lit with wicked knowledge. "You have yet to be properly rewarded," he stated and Jim shivered. He thrust two fingers into Jim's entrance and the blonde cried out. "You are indeed loose and lubricated," he stated, voice slightly husky.

"You found that as enjoyable as me, didn't you?" Jim panted.

Spock inclined his head and settled so that the tip of his double-headed, green-tinted, cock rested against his entrance. Jim moaned at the sight. His companion paused. "Are you a xenophile?" he asked, head tilted in curiosity. Jim nodded. "Well-suited indeed," he murmured and shifted forward so that the first head of his cock entered Jim's entrance. They both moaned – though Spock was much quieter than Jim. Another shift and the second head breached the blonde. Spock took an even breath, fighting against the urge to plunge deep.

"Do it," Jim urged. Spock arched an eyebrow. "Thrust your long, thick cock into me," he urged. "I want all of you in me now, and I know you want it too. Please, Spock, do it." The half-Vulcan hesitated. "I know my body, I'll be fine," he reassured.

Holding him to his word, Spock thrust hard, sheathing himself in a single stroke. Jim cried out, fisting his hands in the covers as his pleasure ratcheted higher. Spock was forced to breathe deep once more, fighting for the control needed to give Jim the time he needed to adjust.

Jim shifted his legs, his intent to wrap them around Spock's waist clear, and the brunet stilled them with gentle pressure. The blonde blinked at him, and Spock hooked his elbows beneath Jim's knees, urging his legs up and out. The human moaned, looking up at him with beseeching, need-filled eyes.

Spock set a hard, fast pace, trusting that Jim could take it. Judging from the moans that spilled from his lips, he enjoyed it thoroughly regardless. He shifted his hips slightly, his shaft grazing a sensitive bundle of nerves, and Jim orgasmed, his walls tightening so completely, that Spock followed him a split-second later.

He carefully set down Jim's legs, gently rubbing them to encourage circulation, using the task as a focus to level his breathing.

"If all my rewards are going to be like that, I hope all my plans work out as well," Jim panted with a grin. Spock's lips curved upward. "What?"

"I am not finished with you yet Jim," he stated.

"Dear God," Jim breathed as he shivered violently.

"You have never been sated?" Spock demanded.

Jim licked his lips. "I've cum, obviously," he reassured quickly. "But I've never gotten to the point where I couldn't go another round," he stated, lifting a negligent shoulder. "None of my partners could match my stamina."

"Challenge accepted," Spock stated and leant down to claim his mouth in a heated kiss full of promise. He pulled back, smirking at Jim's blink. "Not only will I ensure you are sated before we finish today, Jim, but I will do my utmost to ensure it in the future – around our duties," he added.

"Don't worry, I expected the caveat," he murmured. He scraped his teeth over his bottom teeth. "Are you sure?"

"I think it is time you were as thoroughly satisfied as all your past lovers were," he stated fiercely.

Jim raised a tentative hand, and Spock leant his cheek against it. "Are we in a relationship?"

"Yes. Do you have a problem with that?" Jim shook his head rapidly. Spock's lips curved. "Tell me the thought that went with that?" he requested.

"You've got the most beautiful cock I've ever seen," he stated. "And if you follow through on your promises, then you'll ruin me for other men," he added breathily. "I really hope you don't get tired of me."

Spock laid his hand over Jim's. "I might get concerned, or angry when you risk your life, however, I doubt I could ever truly tire of you Jim," he spoke honestly. "Shall I deliver on my promise?"
