Smile while crying out in pain!!! A shy and extremely serious girl who had no friends as a child and always relied on her older sister to play with. On the morning of the shoot, arriving at the studio, she trembled her lips and whispered, "I'm really nervous..." But at that moment, she never imagined she would end up smiling while having a cock forced deep into her throat. This is the record of a deeply personal, masochistic AV in which the pure-looking actress Ena Yuzuriha endures having her throat drilled, maintaining a smile no matter how deep the penetration. Even as her throat is tortured, she desperately keeps smiling, obediently taking the cock in her mouth. Her broken yet compliant smile powerfully stirs something deep within the viewer.
