Belly Button Torture Volume 3 Kumi Mitsuya

Art teacher Kumi Mitsuya is asked by her colleague and fellow art instructor Yamamoto to pose as a nude model for a sketching session. But as soon as sketching begins, Yamamoto freezes—unable to draw because Kumi keeps fidgeting, unable to keep still due to her sensitive belly button. Claiming it's for the sake of art, Yamamoto asks permission to touch her navel. Inspired by the sensation, he decides to make a plaster cast of Kumi's belly button. He then takes it further, using paint to create a bold artistic expression directly on the cast. In the second segment, Kumi returns home from school and steps into the shower to wash off the paint from her navel, when her boyfriend Susumu arrives, leading their relationship into uncharted, intimate territory.
