Newcomer Risa-chan makes her debut in Kupa! First, she greets everyone while shyly opening and closing her vagina with "kupa kupa." Risa-chan has an expression that seems like she's about to say, "I've never said anything like this before..." Despite this, she makes a concerted effort to "kupa kupa." As always, the camera directly below is also equipped, allowing for a thorough observation of Risa-chan's vagina. This is a work where you can enjoy two types of poses: standing and M-leg split.
