A/N: This is super long. I'm not even going to apologize because I write what the story needs so consider it a warning. If you want a short imagine you better go elsewhere. If you like them long, you're in the right place. :)

This one was requested by mateapejic. Hope you like it!

You had a unique role on the Enterprise. You had been trained in multiple areas so you could fill in as needed around the ship. As such, you had a much larger base of friends than most onboard as you'd worked with almost everyone. So you weren't that surprised when you stepped onto the lift to be greeted by a smiling Captain Kirk and Commander Spock.

"Y/N, nice to see you. Where do we have you working this week?"

"Engineering, Captain." Captain Kirk was an attractive man, but he wasn't the one that captured your attention. No, you'd been crushing on a certain Vulcan science officer since the academy. "Commander Spock, happy birthday."

He gave you a tight nod and an emotionless "Lieutenant," without meeting your eyes. 

"How many times have I told you to call me Jim, y/n?" the captain asked with a flirty grin.

"Captain, I believe Lieutenant y/l/n would be uncomfortable with that familiarity," Spock spoke before you could say anything. 

You glanced at him in surprise and your cheeks heated. 

"Since when do you know so much about y/n, Spock?" Kirk asked with amusement in his voice. 

The Vulcan cleared his throat and if you weren't mistaken there was a green tinge to the tips of his ears. "I have merely taken the opportunity to observe the lieutenant when we worked together and have found her to be observant of protocol without being overly severe."

Kirk hummed and looked between the two of you as the lift stopped. You stepped out with a nod and turned left. "Woah," Kirk said, stopping you. "Aren't you coming to the party, y/n?"

You took a breath before turning around. Kirk waited for an answer with lifted brows while Spock stood with his hands behind his back looking as cool and collected as always. You mirrored his position to keep yourself from fidgeting with your hands. "Please don't take offense Captain when I say that it seems rather illogical to have a party for someone who most  likely does not celebrate their birthday. I thought perhaps Commander Spock would be more comfortable with less people there."

Kirk looked between both of you again and grinned. You weren't sure what that look meant but you were quite certain you didn't trust it. Your captain was definitely up to something.

"I appreciate your consideration, Lieutenant y/l/n, but I assure you that your presence would not be disruptive in the least," Spock said.

Kirk clapped a hand on his first officer's shoulder. "What Spock here is trying to say is he would be devastated if you didn't come."

Spock turned to him and arched a brow which was fortunate because it meant he didn't see your cheeks flare red. "I do not recall having lost my capacity for speech, Captain. Nor do I recall asking for your assistance."

You stepped forward before they sniped at each other anymore. "I would be happy to attend. Thank you, sirs." You strode past them and headed down the hall without waiting for them. It only took a second for them to catch up and escort you to Spock's birthday party.

"y/n!" Uhura waved you over as soon as you stepped through the door. 

You smiled and made your way over to find her sitting with Chekov, Sulu and Dr. McCoy. "Hello, all." They all greeted you warmly and McCoy pulled out the empty chair on one side of him and motioned for you to sit.

"Lieutenant y/l/n, just the person I wanted to see," McCoy said.

"Why's that, Doc?" McCoy was one of your favorite people on the ship. It hadn't taken you long at all to break through his gruff exterior and become friends. Currently he sat with his hand protectively around the bottle of whiskey you'd given him for his birthday.

"Because, I intend to show these youngsters how to hold their liquor and require your assistance."

"Why do you always find it necessary to talk like an old man, Bones?" Kirk said, stepping up behind you and patting his friend on the shoulder.

"Can it, Jim," McCoy snapped. "Are you joining us or not?"

"Like you had to ask," he said and dropped into the chair on the other side of the doctor.

You glanced over your shoulder looking for Spock only to find him standing silently right behind you. "Would you like to join us, Commander? It is your party after all." You were extraordinarily proud of yourself for getting out two whole sentences without stuttering or blushing.

"I do not understand the joy humans find in drinking excessively, but yes, I will join you." He took the empty chair next to you. You smiled and turned to McCoy. "So what's the plan, Doc?"

"A drinking game obviously," the captain said and leaned across McCoy looking at you with narrowed eyes. "How come you'll call him Doc but won't call me Jim?"

You smirked. "Last I checked, Doctor was not, in fact, Dr. McCoy's first name."

Kirk's eyes lit up as if he'd just figured something out. "Then Kirk. Call me Kirk. That's an order."

"Captain--" Spock started but you laid a hand on his forearm cutting him off.

"It's fine, Commander. We are off duty. And Kirk is less of a mouthful than Captain."

"Yes," Kirk said and pumped his fist.

Everyone at the table laughed well aware of the fact Kirk and Spock were the only two on the ship you always called by their rank. You glanced around the room with a frown. "Where's Scotty?" you asked.

McCoy laughed. "Holed up with that bottle of Scotch you gave him last Christmas. He sends his regards, Spock."

"I spoke to Mr. Scott earlier today. I believe his regards were adequately conveyed at that time Doctor." Him speaking only served to remind you of his closeness and you took a deep breath to keep from blushing.

McCoy rolled his eyes and turned back to Kirk. "What sort of game?"

Kirk shrugged.

"It is not a game without rules, Ceptin," Chekov said.

Uhura nodded. "And a prize. What's the point of playing if there's nothing to win?"

"The next three days off. If you win this, you're going to need it to recover," Kirk said with a grin. 

Everyone enthusiastically agreed. Well, everyone except Spock who just looked at his captain with that arched brow. 

"Then I know just the game," you announced.

The game you suggested was called Drowning Liars. You went around the table and took turns stating something about yourself then everyone had to guess if it was a truth or a lie. If they were wrong they had to drink. If everyone guessed correctly, the teller had to drink. It was a fun game and you were all laughing loudly before long. You found it especially hilarious that Spock had to drink every time it was his turn because Vulcans don't lie so everyone always guessed truth.

It was several hours later and Chekov, Uhura and Sulu had long since given up and stumbled to their rooms. Kirk had his head laying on his arm on the table and was barely coherent. McCoy looked exhausted and grumpy, but he always looked grumpy so that was nothing new.

Sometime after the other three left, the four of you had devolved to just taking shots. Your face was mostly numb. In fact, you were pretty sure your teeth were numb. Was that even possible? But you were still coherent and so was Spock. In fact the only difference you saw in the Vulcan was that he looked relaxed. If anything, it only made him more attractive. You frowned at the thought. Drunk you could get in a lot of trouble with those kind of thoughts.

You swallowed another shot, enjoying the burn. McCoy slammed his glass down on the table and Kirk didn't even try drinking. "That's it. y/n and Spock win. I give up."

"Noooo," Kirk slurred and you bit your lip to keep from laughing at your captain. "I'm still good."

"Damn it, Jim. I'm a doctor, not a mortician. You drink any more and you're going to be a corpse," McCoy lectured as he got to his feet. With Spock's help, they got Kirk up and looped his arm over McCoy's shoulders. "I've got him, Spock. Happy birthday."

"Indeed, Doctor. Thank you." He resumed his seat and you both simply looked at each other for a long moment.

You got to your feet. "I'll be right back. " On a table along the side of the room were a few gifts for Spock. You found the box you had dropped off earlier in the day and carried it back to the table. 

He examined the box when you sat it in front of him as if unsure what to do with it. 

"Open it, Spock."

His eyes darted over to you then back to the present. He opened the package as methodically as he did everything else, carefully pulling the paper back. You made a mental note to use a gift bag next time. Once he finally got the paper off, he lifted the lid on the box then looked at you with lifted brows. He pulled out the bottle nestled inside with utmost care. It was a delicately cut bottle filled with a pale amber liquid. He took the lid off and smelled the contents. 

"Vulcan brandy," he breathed. There was no mistaking the surprise in his expression. That told you the alcohol had effected him more than anything else he'd done so far. "Where did you find this, Lieutenant?"

"I have my sources," you told him. You weren't about to mention the trouble you'd went to or how much it cost. Though he was probably already well aware.

His eyes studied you and your cheeks heated. At the same time his cheeks and ears turned a pale shade of green. After a moment he cleared his throat. "It seems only fitting that I share this with the one who went to such trouble to procure it." He gestured at your glass. "May I, Lieutenant?"

***

You woke with the pleasant taste of Vulcan brandy still coating your tongue. Your head hurt but not as bad as it should have considering the night before. For that you were grateful. Not wanting to get up yet, you kept your eyes sealed and nestled into the bed. Why was it so warm in here? And why was your pillow so firm? You started to move your hand to fluff it only to realize that something had your hand captured. 

Slowly you opened your eyes to be met with an expanse of pale, leanly muscled chest. You froze even as your breathing sped. A glance at your hand showed your fingers entwined with someone else's and laying on his stomach. Tilting your head back slowly so as not to disturb your bed partner, you were met with Spock's handsome features. 

Part of you was mortified, the rest of you wanted to run your fingers through his hair and kiss his lips. What the hell happened and why didn't you remember? It wasn't like you to blackout regardless of how much you drank. That Vulcan brandy must pack a serious punch.

You put your head back in its original position as you debated whether to attempt to sneak away or to just stay this way as long as possible. It wasn't as if you were ever going to get this opportunity again. At least you still wore your sports bra and underwear. You'd hate yourself if you actually had sex with your crush and couldn't remember it.

Suddenly you realized that the movement of Spock's chest had changed as he awoke. Rather than immediately kicking you out as you expected, his free hand played with your hair where it lay on your back and he ran his thumb across the skin of the hand holding his. That was when you remembered Vulcans kiss with their hands. Maybe he wanted this as much as you did? Your heart began to pound at the thought. "Lieutenant?" he sounded unsure, confused.

He hadn't even used your name. Of course he didn't want this. How stupid could you be to even consider it? You jerked your head back to meet his gaze and found him frowning at you. You quickly untangled yourself from him and hopped out of the bed. "I am so sorry, Commander. I don't know what happened. I never meant for this to happen. I just wanted you to have a good birthday and I really wanted those three days off and--"

"Lieutenant!" Spock said sharply as he sat up in the bed and swung his legs over the edge. 

You ignored him and kept looking for your clothes. Where the hell were your pants? "I probably threw myself at you. I should have known something like that would happen after trying to hide it for so long. I'm such an idiot--"

"Y/N!"

That got you to stop. Spock had never called you by your first name before. A strong hand wrapped around your wrist and pulled you back toward the bed. He turned you until you were facing him, though you found it impossible to meet his eyes.

"Am I to understand that you are not upset over finding yourself in my bed, but rather at the thought that you initiated whatever happened?" His voice rolled through you, calming you as it always did. He didn't sound angry. In fact, he sounded almost...hopeful?

You looked up to see his blank face waiting for an answer. You took a deep breath deciding you might as well tell the truth. It wasn't like you could make things any worse. "If I'm completely honest, Commander, I've been in love with you since the academy. I obviously drank enough that I wasn't fully aware and initiated romantic contact with you. I am sorry--"

He reached out and interlaced his fingers with yours. Your eyes widened in surprise and only grew wider when the Vulcan's mouth twitched in a semblance of a smile. "I believe it is time I told you that I have had similar feelings for you since you were assigned to the Enterprise. I refrained from mentioning before as I am your superior officer and did not want you to feel pressured into a relationship with me."

The weight that had been in your chest since you woke lightened with his words. He loved you back. You leaned forward and pressed your lips to his. It took him a second but eventually he kissed you back and pulled you closer to his body. You finally got the chance to run your fingers through his hair as you held his head to yours. "I love you, Spock," you said as you pulled away.

"And I am very fond of you, y/n."

You smiled and leaned your forehead against his. "Spock? How logical would it be to spend the next three days in bed?"

"That would not be logical at all, y/n." You heart sank a bit in disappointment at his words. "However, as you may recall, I am half human and your species tends to not be very logical at all." He scooted back into his bed and pulled you up with him.

You soon found yourself in much the same position as you had been when you woke. "Happy birthday, Spock."
