This is the story of David, a timid foreign exchange student who becomes entranced by Akane, a dominating and alluring Japanese college girl. Despite his initial reluctance, David finds himself unable to resist Akane's magnetic presence and seductive power.

As she pressures him into making the life-altering decision, he finds himself agreeing to serve as her toilet slave. Within their secret arrangement, Akane's dominance pushes David to explore and embrace taboo desires, pushing the boundaries of his psyche.

As David struggles with his new life, he must come to terms with his new-found identity and what it means for his relationship with the enigmatic Akane. As the weeks go by, Akane further established her control over David, turning him into her personal toilet.

She delighted in watching his gradual transformation, firmly training him to serve her every need. Their encounters became more frequent and intimate, and David found it harder and harder to concentrate on anything else in his life.

As his entire existence now revolved around Akane, David started to lose touch with his friends and even his classes. Phone calls from his worried parents went unanswered, as each day he felt more enveloped by the dark world Akane had introduced him to.

David's devotion to Akane and her bodily wastes grew, driven by her insatiable dominance and a perverse desire to please her. She would degrade him in various ways, making him wear a collar and leash that only she was allowed to handle.

She would often skip meals and gorge on certain foods to ensure that her scents and substances would be even more pungent to David, testing his devotion further. .
