NEO-930 Fetishism for the beautiful, flexible arching of women. The protagonist is Riria Hido.

Film Introduction

She's a tea-haired gal now, but she used to be a figure skating athlete, Riria-chan. Her signature pose is the Y-balance. Using her flexibility, she bends her body into various poses and shows off her arched neck. Plus, if you watch the video closely, you might notice that her lips look just like those of the beautiful entertainer Ishihara Yuumi.
