High Quality Content by WIKIPEDIA articles! Kirk/Spock, also commonly referred to 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 on, a few fan writers started speculating about the possibility of a sexual relationship between Kirk and Spock, adding a "sexual element" to the friendship between the men. As of 1998, "most" academic studies on slash focused on Kirk/Spock, as Star Trek was one of the most accessible titles for academics and their audience, and as the first slash pairing, K/S was developed independently from the influence of other slash fiction.
