Kirk/McCoy
Snow Country by
ayalesca (Kirk/McCoy, PG-13, 12,000 words)
Summary:Jim dies and arrives in the afterlife to find that "eternity" is a single memory that he must choose from his lifetime. He also meets McCoy -- who died before the first mission ended, and who won't tell Jim why he hasn't been able to move into the afterlife ...
Notes: If you need a good cry, this is your fic.
Sleeping in the Flowers by
janice_lester (Kirk/McCoy, R, 3,000 words)
Summary: Something in the local environment gets the landing party a wee bit high. Shenanigans ensue.
Notes: I often type "LOL" when I don't literally mean it, but this fic had me giggling from start to finish. Poor long-suffering Spock has to baby-sit Jim and Bones when they're high as kites off some foreign intoxicant. Comic brilliance.
Downshift by
thalialunacy (Kirk/McCoy, NC-17, 2,803 words)
Summary: Jim + Bones + Holodeck = shenanigans. Of the sexy kind.
Notes: This is a sweet getting-together fic and it's quite sexy too (though for my money the hottest image here comes before the actual porn -- it involves Bones and a car, and you'll know it when you see it).

The Big Four Oh by
skyblue_reverie (McCoy/Chekov, NC-17, ~3300)
Summary:It's McCoy's party, and he'll cry wallow in self-pity if he wants to.
Notes: McCoy's voice is spot on here. I also like how Chekov is still Chekov, but somehow matured. Plus lines like Now he was having the kid's mother procure shit that he could use to jerk off while thinking about her son contribute to this story being total win.
