Azumi, a married woman, is shaken by Kyoko's gaze but is forced into embarrassing poses and experiences the pleasure of shame. Kyoko uses oil not intended for massage to touch her, wetting Azumi's panties until the crotch becomes translucent, and Azumi's heightened sensitivity leads her to crave it herself. The sexual pleasure between the women escalates day by day, until they pursue each other to the point of foaming and losing consciousness.
