In this fourth installment of "Bible Black The Infection," Peace, the busty, petite school nurse, finds herself ensnared in a web of taboo lust. Her innocent allure belies a hidden desire, awakened by the sinful visual novel she's been playing. As she delves deeper into the game's depraved world, her own inhibitions crumble. Her hands tremble as she tentatively touches herself, her moans echoing in her empty apartment. But guilt gnaws at her. She's a woman of faith, after all. Yet, her body yearns for more, craving the forbidden fruit she's been denying herself.
