[1] In the episode, unsatisfied with missionary sex, Francine finds out she has a spanking fetish when Stan tries to punish Steve.
Stan finally catches her tossing Steve's bicycle through the front window and decides to banish Francine to the woods as per a fake verse in his Bible as punishment.
Rob H. Dawson of TV Equals gave the episode a positive review, saying "It’s also nice to see an attempt at a multi-episode plot, the kind of thing American Dad usually doesn’t go for.
But that was a minor thread in "The Missing Kink," an episode that, barring one big, singing exception, kept up the funny for most of its running time.
Club gave the episode a B, saying "It’s still fun to laugh at Stan for his strict conservative ways, but I’m glad that American Dad doles this type of story out in smaller parcels than it used to.
"The Missing Kink" may end in an unsatisfying way, returning to the same boring Smith sex life, but with Francine indulging elsewhere, but it still contains enough laughs and outlandish visuals to outshine the rough patches.
