Yuzu-chan, 18 years old, is active as an underground idol. She is usually in charge of the yellow color of the group and is active as an energetic character. This time, we filmed Yuzu-chan having sex for the first time*. Yuzu-chan, who is always cheerful, has a distorted expression due to embarrassment.
