Kimijima Towa and other married women engage in the forbidden act of "gokkun" by shoving the semen of a man other than their husbands down their throats. These young wives, who have never even swallowed their husband's seed before, tremble with a sense of immorality, but their anticipation of the unknown taste and smell grows. They wait with their mouths open, desperately trying not to spill a single drop of the hot semen being released in front of them. The sight of them swallowing it down with a gurgle, and then showing us their empty mouths with satisfaction, is filled with the pleasure of having completed their betrayal of their husbands.
