Former Kansai weather presenter Riho Matsumoto makes her first appearance with Black male partners. Her husband's acquaintance Mike, a world-famous photographer, chooses Riho as his model. As the shoot progresses she relaxes, but Mike demands increasingly explicit poses to break down her emotional barriers and produce world-class photographs. He then exposes her to his Black assistants' enormous cocks to draw out her sensual side; while her husband watches in distress, Riho is stunned by sizes he cannot match, and begins to succumb to them.
