Debut work of the idol Yui Koharu, who exudes a pure and innocent charm yet gives her all when serious! Her figure has evolved from a C cup to a stunning E cup in just half a year, showcasing a firm, shapely physique that looks as fresh and vibrant as ripe fruit. In her first bold poses, the soft tips of her breasts gently protrude, revealing a supple yet firm fullness. Her plump, round hips stand out with lush volume, powerfully facing the camera. The sight of this innocent girl running, her entire body trembling with motion, conveys both the excitement and nervousness of a first challenge. That very first step marks the unforgettable, eye-catching beginning of something intense!
