With the recent passage of Nichelle Nichols, "The Kiss" has gotten a lot of airplay, but what hasn't gotten even a mention in any forum I've heard is that the kiss was coerced. It was, in essence, a sexual assault, on both Uhura and Kirk, as he would not willingly engage in such conduct in such a circumstance. (Although, Kirk's behavior with the slave girl in "Bread and Circuses" was morally questionable.)
