With the number of times Kirk had asked him to tell why he loved him, the thought had never occurred to ask Kirk the same. Spock only found it logical, opposites attract, and Spock was opposite of Kirk. Spock was intelligent and attractive; he also was a good companion for the Captain who needed constant attention. Spock was only too happy to tell his love to shut up and Kirk was only too happy to ignore it. Spock slid back off of Kirk's heated body and against the cool sheets that covered Spock's bed. After a long time Spock looked over at Kirk who had his eyes shut and wore a content smile. "Captain." Spock said rousing the other from his reverie.

"Hm?" Kirk responded as his fingers danced across Spock's pale chest.

"When did you know you loved me?" Spock asked. He generally avoided such indefinable words as love. To him, love was chemicals.

"Why are you asking?" Kirk opened his eyes to give his mate a quizzical glance. Spock was silent. Why was he asking? He had just been thinking about how odd it was the thought had never occurred to him. It had never even seemed like a question, they simply were. They were together, it was simple and logical and Spock never had a reason to question it. So why was he suddenly asking? Kirk took his boyfriend's silence as a suggestion he just answer the question and to stop asking stupid questions of his own. "Well at first you were just an obnoxiously attractive ass. But then I realized there was something under that haughty stuck up teacher's pet." Kirk said musing on the long path he had traversed to fall in love with Spock. "You turned out to be a real good boyfriend."

"It is only logical we would be good together." Spock said looking up at the celling.

"What?" Kirk asked.

"We are opposites, and opposites attract." Spock said warily. Kirk thought about this idea for a moment. After a long time Kirk smiled broadly. "You are like a dog, and I am a cat." Spock said looking down at their hands, Kirk had interlocked their fingers.

"But enough of that, we should get up." Kirk said beaming. He'd never known Spock thought things like that, thought of them. Spock had never shown any signs to be thinking of Kirk but not the captain knew he did, Spock thought often of his beloved. And that pleased him.
