Kirk/Spock

Kirk/Spock, also commonly abbreviated as "K/S" and referring to James T. Kirk and Spock from Star Trek, is a pairing popular in slash fiction, possibly the first slash pairing, according to Henry Jenkins. Early in the history of Star Trek fan fiction (which began very soon after the television show debuted in 1966), a few fan writers started writing about a sexual relationship between Kirk and Spock, adding a romantic or sexual elements to the friendship between the men. As of 1998, most academic studies on slash fiction focused on Kirk/Spock, as Star Trek was by that point one of the longest-lived and most popular subjects of slash fiction, while its mainstream popularity made it one of the most accessible titles for academics and their audience, As the first slash pairing, K/S was created and developed largely independently from the influence of other slash fiction, with most of the conventions of the slash genre seeing their debut first in K/S slash.
