Fact: Spock has boobs.

Fact: this is quite possibly the happiest day of Jim Kirk's life thus far.

(Fact: CRACK WARNING. Also, heterosexuality ahead.)

"Turnabout Intruder" AU. Jane Kirk isn't looking forward to her reunion with ex-girlfriend Janice Lester, but she doesn't expect Janice to swap their bodies in an attempt to take her place as captain. Now her only hope is to convince her friends – and girlfriend – of her true identity, and stop Janice before it's too late.

SEQUEL TO Captain's Woman. Captain James Kirk of the ISS Enterprise and Commander Spock have been dating for a year and are planning on bonding. However, things start to go wrong when they encounter Janice Lester and she tries to use Spock for her own enjoyment... What better way to ruin James Kirk than to ruin his soon-to-be wife and bondmate?

Like any woman, Spock is willing to be fierce...it didn't help that there was no such thing as Midol.

Aprés une mission épuisante, Kirk et son équipage rentre pour une permission bien méritée. Mais une nouvelle mission vient interrompre leur voyage, une bien plus difficile encore...Slash Spock / Kirk

A response to KrazieKat2009's challenge "And they fell in love".

I do not own almost anything here: the idea belongs to KrazieKat2009, and the STAR TREK is property of Paramount Pictures; only mistakes and typos are mine. And I have only recieved immaterial joy for writing this.

A fairly standard Amok Time story starring approximate female parallels of Kirk and Spock.  Vulcan Starfleet officer T'Vei struggles with her feelings of love and lust for her commanding officer when she goes into Pon Farr.

First story so please dont hate. Appreciate.

In the middle of their 5 year mission they get involved with a being named Q. He's the Q of all Q's. He is very powerful and just so happens to love the relationship that every Spock and Jim has in every universe. But when his favorite universe doesn't go the way he wants it he changes it to his liking. For instance giving Jim a new organ and a little time to confess to Spock about his new feelings for him. But if he doesn't when that time is up they might lose someone dear to them.

There are a few surprises in here so don't get too happy when you read about them. 

Jim and Spock get turned into women after the meddling members of a matriarchal society decide it's the only way to get them to acknowledge their feelings for one another. K/S slash. Rating may go up.

He's getting ahead of himself.
