Smile while choking in agony!!! Yua Nanami, a beautiful girl who seems to have stepped out of a fairy tale, finds herself in a humiliating predicament—forced to keep a smile on her face no matter what as she takes a cock deep into her mouth. Her innocent, pure smile and childlike expression gradually lose their radiance as her throat is relentlessly violated, until she can no longer hold back her tears, which begin to stream down her cheeks. Yet, obeying the cruel command to "keep smiling," she loses all sense of self, her emotions overwhelming her until she breaks completely. The stark contrast between her innocence and the brutal coercion intensifies the emotional torment on display.
