[JIBAKU-SYSTEM (Suzuki Amaharu)] The book is an incest story about a niece and an uncle.

An anxious schoolgirl in a tight uniform finds herself alone with her uncle in a cramped bedroom, her body trembling as she confesses a forbidden desire. The uncle, a looming figure, presses his hand against her thigh, promising a secret that will ruin her innocence while she gasps, her cheeks flushed and eyes wide with shock. The scene escalates with a sudden burst of pleasure, her body convulsing as the uncle's hand slides beneath her skirt, the tension between taboo and desire reaching a feverish climax.
