Right after her debut, the job she accepted for the day was an "image AV shoot." However, an unexpected turn of events awaited her. As the camera obsessively focused on her buttocks, she would soon discover the reason why. The director's demands were far beyond mere filming—they led her hidden erogenous zones onto a new stage. Her previously untouched depths were stretched open by men's fingers and foreign objects, then penetrated by a male organ. At that moment, a new sexual desire within her blossomed. Still carrying the innocence of a newcomer, Yuu would begin walking a new path from this shoot onward. The shocking experience of her first anal deflowering would drastically change her life.
