Tanaka's monthly rent payment takes a variety of provocative forms as his landlady, Miyuri, engages him in "lessons" while dressed in formal attire and a lab coat. The excitement peaks when Miyuri dons a revealing, stretchable costume from a recent air show, leading to an intense and playful encounter. After their passionate exchange, Miyuri playfully suggests that Tanaka's rough behavior might lead to a rent increase next month.
