This debut work features newcomer actress Maiko Mizuki, completely inexperienced in front of the camera. In private, she has had minimal experience with men and comes across as shy and reserved, yet harbors a secretly perverted, lustful side deep within. In this video, she experiences deep throat for the first time—a fantasy she had only imagined until now—making this an especially compelling debut. Attempting to develop her virgin throat, even slight stimulation with a toy brings unprecedented dull pain, causing her to instinctively resist from sheer agony. Yet, as she desperately endures through tears and drool, her deeply buried female masochist side begins to awaken. This title captures the transformation of a deep-throat novice, showcasing her intense journey through her first experience, making it a standout debut release.
