Three years into their five year mission, Female Jim's biological clock starts ticking. As she is currently unattached and Spock is in a relationship with Uhura, she at first turns to Bones for help in making the ticking stop.

When he doesn't agree, it's purely by chance that Spock overhears a conversation regarding Jim's need for a child and logically deduces that as he is her other best friend he should do everything he can to help her. After all, there is no reason why copulation for breeding purposes should lead to any emotional investment from Jim or any jealousy from his intended.

Note to all readers: Uhura is a jealous cow, Jim is an jealous bitch and Spock is just clueless in most things relationship wise. If you want canon true-to- character-down-to-the-last-follicle readings of them... I'm afraid this story isnt for you. I take liberties with their personalities. I do not sadly own anything related to Star Trek.
